In The Mismeasure of Man (1981) Stephen Jay Gould provides a typically readable history of one of our most vexatious intellectual enterprises: the scientific study of intelligence. Gould is successful, as always, in rendering the relevant scientific debates accessible to general readers. What Gould does less well is to carry through his attack on prior attempts to understand natural intelligence scientifically: attempting to muster all possible arguments against such science, he conjures up a variety of impossible arguments as well. One such argument urges that Gould's predecessors are not to be taken seriously because they are racists and have let their racism influence their scientific practice. Gould has no difficulty in demonstrating the influence of racism; where he goes astray is in his dismissal of such prior work as simply unscientific because the racist conclusions preceded the collection of data. Advancing hypotheses prior to experimentation is how all of science proceeds, and is no mark of inferior work. And no science is immune to influences--racist or otherwise--from the culture in which it is embedded, as Gould elsewhere readily acknowledges. Another failed argument claims that all of the factor analysts studying intelligence have committed the intellectual sin of reifying the factors uncovered in IQ tests--concluding that the factors are real solely on the basis of how a factor analysis summarizes IQ data. Gould concludes that factor analysis is worthless for the study of intelligence. However: (1) contrary to what Gould suggests, the factor analysts themselves warned against concluding that the factors "discovered" are physiologically real merely on the basis of a factor analysis; and (2) factor analysis nevertheless remains a strong candidate technique for developing causal models worth investigating subsequently by other means.

Stephen Jay Gould as a political theorist.  

PubMed

Before his death in 2002, paleontologist Stephen Jay Gould elaborated a large and inclusive theory of life's change. In this essay I concentrate on the aspects of Gould's vast theory that have the most direct political relevance. I briefly discuss his views on the philosophy of science. I examine the way he combined political values and methodology in a seamless, critical analysis of intelligence-testing and sociobiology. I concentrate most extensively on the impact his "punctuated equilibria" concept has made on contemporary political analysis, and I demonstrate that in their appropriation of this concept political scientists have violated the rules that Gould himself articulated for its use. In closing, I consider the possibility that a comprehensive theory of life, a theory that must include political values, might approach traditional questions of political thought more satisfyingly than has conventional philosophy.

This view of science: Stephen Jay Gould as historian of science and scientific historian, popular scientist and scientific popularizer.  

PubMed

Science historian Ronald Numbers once remarked that the two most influential historians of science of the 20th century were Thomas Kuhn and Stephen Jay Gould. All historians are deeply familiar with Kuhn's work and influence, and most know of the remarkable impact Gould has had on evolutionary theory through both his professional and popular works. But little attention has been paid to the depth, scope, and importance of Gould's rôle as historian and philosopher of science, and his use of popular science exposition to reinforce old knowledge and generate new. This paper presents the results of an extensive quantitative content analysis of Gould's 22 books, 101 book reviews, 479 scientific papers, and 300 Natural History essays, in terms of their subject matter (Evolutionary Theory, History and Philosophy of Science, Natural History, Paleontology/Geology, Social Science/Commentary), and thematic dichotomies (Theory-Data, Time's Arrow-Time's Cycle, Adaptationism- Nonadaptationalism, Punctuationism-Gradualism, Contingency-Necessity). Special emphasis is placed on the interaction between the subjects and themata, how Gould has used the history of science to reinforce his evolutionary theory (and vice versa), and how his philosophy of science has influenced both his evolutionary theory and his historiography. That philosophy can best be summed up in a quotation from Charles Darwin, frequently cited by Gould: 'All observation must be for or against some view if it is to be of any service'. Gould followed Darwin's advice throughout his career, including his extensive writings on the history and philosophy of science. PMID:12503565

Many ways of being human, the Stephen J. Gould's legacy to Palaeo-Anthropology (2002-2012).  

PubMed

As an invertebrate palaeontologist and evolutionary theorist, Stephen J. Gould did not publish any direct experimental results in palaeo-anthropology (with the exception of Pilbeam and Gould, 1974), but he did prepare the stage for many debates within the discipline. We argue here that his scientific legacy in the anthropological fields has a clear and coherent conceptual structure. It is based on four main pillars: (1) the famed deconstruction of the "ladder of progress" as an influential metaphor in human evolution; (2) Punctuated Equilibria and their significance in human macro-evolution viewed as a directionless "bushy tree" of species; (3) the trade-offs between functional and structural factors in evolution and the notion of exaptation; (4) delayed growth, or neoteny, as an evidence in human evolution. These keystones should be considered as consequences of the enduring theoretical legacy of the eminent Harvard evolutionist: the proposal of an extended and revised Darwinism, coherently outlined in the last twenty years of his life (1982-2002) and set out in 2002 in his final work, The Structure of Evolutionary Theory. It is in the light of his "Darwinian pluralism", able to integrate in a new frame the multiplicity of explanatory patterns emerging from different evolutionary fields, that we understand Stephen J. Gould's legacy in palaeo-anthropology today, both in terms of provocative shocks to comfortable visions of human evolution and, above all, in terms of specific scientific predictions about future research.

Stephen Jay Kline on systems, or physics, complex systems, and the gap between.  

SciTech Connect

At the end of his life, Stephen Jay Kline, longtime professor of mechanical engineering at Stanford University, completed a book on how to address complex systems. The title of the book is 'Conceptual Foundations of Multi-Disciplinary Thinking' (1995), but the topic of the book is systems. Kline first establishes certain limits that are characteristic of our conscious minds. Kline then establishes a complexity measure for systems and uses that complexity measure to develop a hierarchy of systems. Kline then argues that our minds, due to their characteristic limitations, are unable to model the complex systems in that hierarchy. Computers are of no help to us here. Our attempts at modeling these complex systems are based on the way we successfully model some simple systems, in particular, 'inert, naturally-occurring' objects and processes, such as what is the focus of physics. But complex systems overwhelm such attempts. As a result, the best we can do in working with these complex systems is to use a heuristic, what Kline calls the 'Guideline for Complex Systems.' Kline documents the problems that have developed due to 'oversimple' system models and from the inappropriate application of a system model from one domain to another. One prominent such problem is the Procrustean attempt to make the disciplines that deal with complex systems be 'physics-like.' Physics deals with simple systems, not complex ones, using Kline's complexity measure. The models that physics has developed are inappropriate for complex systems. Kline documents a number of the wasteful and dangerous fallacies of this type.

The rhetorical construction of Eldredge and Gould's article on the theory of punctuated equilibria in 1972.  

PubMed

This article seeks to show how several rhetorical tools were used and, in fact, played a central role in the argumentation advanced by Niles Eldredge and Stephen Jay Gould in their 1972 seminal article on the theory of Punctuated Equilibria. It is analyzed how Eldredge and Gould proceeded through three steps that, sequentially integrated, made their argument compelling. It is shown how they made use of analogies, metaphors and other rhetorical tools. It is sustained that they began by priming the reader to distrust the current interpretation of the fossil record offered by most paleontologists and then, in a second step, they used specific visual representations in order to suggest that the competitor theory was committed to the idea of an even and slow evolution at a constant rate, an image utilized by them as straw man. Finally, it is analyzed how, in their third step, Eldredge and Gould made use of several rhetorical arguments to present their theory as new for paleontology while, at the same time, placing it well inside the frame of the modern synthesis, and how they also managed to present their theory as more promising and capable of making predictions for future researches than the competitor theory.

Benjamin Apthorp Gould and the Founding of The Astronomical Journal  

NASA Astrophysics Data System (ADS)

The origin and vicissitudes of The Astronomical Journal are inextricably bound up with the extraordinary career of Benjamin Apthorp Gould (1824-1896), the first American to obtain a PhD in astronomy (at Gottingen). Returning to Cambridge in 1848, Gould joined an informal group known as the Lazzaroni, who were determined to bring professional standards to American science. Gould devoted much of his life to professionalizing American astronomy, and his founding of the AJ was part of this strategy. Beginning on 2 November 1849, Gould's AJ was issued at irregular intervals, seldom shorter than two weeks and occasionally much longer, such as the two-month gap in 1851 when Gould had gone to the solar eclipse in Europe. About 20% of the space was devoted to asteroids, then the hot topic in astronomy. The 11th issue announced the discovery of the 11th asteroid; by March of 1853, 23 asteroids were known, and Gould editorialized about the "threatened consumption of astronomical energies." In 1856 the trustees of the newly-founded Dudley Observatory agreed to support the financially struggling AJ, and volume 5 (1856-58) bore the Albany dateline though printing continued in Cambridge. Gould's ill-fated directorship of the Dudley Observatory lasted only a year in Albany itself, and volume 6 was again edited in Cambridge. The Civil War then brought a 25-year hiatus to Gould's journal. In 1870 Gould went to Argentina, where he founded the Argentine National Observatory in Cordoba; he returned to Cambridge in 1885, and very shortly thereafter resumed publication of the AJ (in November, 1886). He continued his editorship for a decade, producing volumes 7-16; his last issue, vol. 17, no. 4, is dated just two weeks before his death. As his successor, Seth Chandler wrote, "Of all the great enterprises of his life, this is the one which he has most cherished."

The discrete Gould transform and its applications  

NASA Astrophysics Data System (ADS)

We present a new discrete transform, the Gould transform (DGT). The transform has many interesting mathematical properties. For example, the forward and inverse transform matrices are both lower triangular, with constant diagonals and sub-diagonals and both can be factored into the product of binary matrices. The forward transform can be used to detect edges in digital images. If G is the forward transform matrix and y is the image, then the two dimensional DGT, GyGT can be used directly to detect edges. Ways to improve the edge detection technique is to use the "combination of forward and backward difference", GT(Gy) to better identify the edges. For images that tend to have vertical and horizontal edges, we can further improve the technique by shifting rows (or columns), and then use the technique to detect edges, essentially applying the transform in the diagonal directions.

Possibly most moving is Bruce Conner's film on DeFeo's most famous painting, "The Rose" (1958âÂÂ66). DeFeo worked on the painting for eight years, until it took up an entire room of the apartment she shared with her husband, Wally Hedrick (1928-2003) and weighed roughly a ton. Conner's short film documents the day when "The Rose" was removed, since DeFeo and Hedrick had been evicted. It was shown twice in California, in 1969. Another video, "The afterlife of Jay DeFeo's The Rose" documents the conservation of "The Rose" in June of 1995, after spending 25 years in storage. After conservation, "The Rose" travelled to New York City, where it was featured in the Whitney Museum's exhibition, "Beat Culture and the New America, 1950-1965."

Stephen FosterÂs Sketchbook  

NSDL National Science Digital Library

Raised in and around Pittsburgh during the 19th century, Stephen Foster grew up singing in an all-male secret club and receiving some modest musical training from a local German immigrant, Henry Kleber. He soon became intensely interested in song-writing, and his first published song, ÂOpen Thy Lattice LoveÂ, appeared when he was 18. Of course, he went on to write around 285 songs, including such old chestnuts as ÂBeautiful DreamerÂ, ÂCamptown RacesÂ, and of course ÂOh! SusannaÂ. The University of PittsburghÂs Digital Library has digitized his sketchbook and placed it online for the general web-browsing public. Visitors can search the sketchbook by song title, or simply browse the pages at their leisure. There are a number of real finds here, including drafts of ÂWhile the Bowl Goes Round and ÂThou Art the Queen of My SongÂ.

We examined the prevalence of antibodies to three mosquito-borne arboviruses in blue jays, Cyanocitta cristata, and Florida scrub-jays, Aphelocoma coerulescens, to identify the effects on host survival, the influence of sex and age on infection, and the temporal patterns of antibody prevalence. Blood samples from 306 blue jays and 219 Florida scrub-jays were collected at Archbold Biological Station (Lake Placid, FL) from April 1994 through December 1995. Sera were analyzed for hemagglutination-inhibition antibody to eastern equine encephalitis (EEE) and St. Louis encephalitis (SLE) viruses, and neutralizing antibodies to EEE, Highlands J (HJ), and SLE viruses. Overall, 31.4% of blue jay samples and 22.1% of scrub-jay samples had antibodies to EEE. Antibodies to HJ were detected in slightly >15% of samples in each jay species, and SLE was detected in <3% of the samples in each jay species. A single EEE virus isolation was made from the blood of an 11-d-old scrub-jay nestling. Survival of adult blue jays seropositive to EEE was significantly lower than that of seronegative birds based on resight rates, but infection did not seem to affect survival of adult or juvenile Florida scrub-jays.

Episodic-like memory during cache recovery by scrub jays.  

PubMed

The recollection of past experiences allows us to recall what a particular event was, and where and when it occurred, a form of memory that is thought to be unique to humans. It is known, however, that food-storing birds remember the spatial location and contents of their caches. Furthermore, food-storing animals adapt their caching and recovery strategies to the perishability of food stores, which suggests that they are sensitive to temporal factors. Here we show that scrub jays (Aphelocoma coerulescens) remember 'when' food items are stored by allowing them to recover perishable 'wax worms' (wax-moth larvae) and non-perishable peanuts which they had previously cached in visuospatially distinct sites. Jays searched preferentially for fresh wax worms, their favoured food, when allowed to recover them shortly after caching. However, they rapidly learned to avoid searching for worms after a longer interval during which the worms had decayed. The recovery preference of jays demonstrates memory of where and when particular food items were cached, thereby fulfilling the behavioural criteria for episodic-like memory in non-human animals.

Time Restored - The Harrison Timekeepers and R.T. Gould, the Man Who Knew (Almost) Everything  

NASA Astrophysics Data System (ADS)

This is the story of Rupert T. Gould (1890-1948), the polymath and horologist. A remarkable man, Lt Cmdr Gould made important contributions in an extraordinary range of subject areas throughout his relatively short and dramatically troubled life. From antique clocks to scientific mysteries, from typewriters to the first systematic study of the Loch Ness Monster, Gould studied and published on them all. With the title The Stargazer, Gould was an early broadcaster on the BBC's Children's Hour when, with his encyclopaedic knowledge, he became known as The Man Who Knew Everything. Not surprisingly, he was also part of that elite group on BBC radio who formed The Brains Trust, giving on-the-spot answers to all manner of wide ranging and difficult questions. With his wide learning and photographic memory, Gould awed a national audience, becoming one of the era's radio celebrities. During the 1920s Gould restored the complex and highly significant marine timekeepers constructed by John Harrison (1693-1776), and wrote the unsurpassed classic, The Marine Chronometer, its History and Development . Today he is virtually unknown, his horological contributions scarcely mentioned in Dava Sobel's bestseller Longitude. The TV version of Longitude, in which Jeremy Irons played Rupert Gould, did at least introduce Gould's name to a wider public. Gould suffered terrible bouts of depression, resulting in a number of nervous breakdowns. These, coupled with his obsessive and pedantic nature, led to a scandalously-reported separation from his wife and cost him his family, his home, his job, and his closest friends. In this first-ever biography of Rupert Gould, Jonathan Betts, the Royal Observatory Greenwich's Senior Horologist, has given us a compelling account of a talented but flawed individual. Using hitherto unknown personal journals, the family's extensive collection of photographs, and the polymath's surviving records and notes, Betts tells the story of how Gould's early life, his naval career, and his celebrity status came together as this talented Englishman restored part of Britain's--and the world's--most important technical heritage: John Harrison's marine timekeepers.

Initial Highlights from the Herschel Gould Belt Survey  

NASA Astrophysics Data System (ADS)

The Herschel Space Observatory provides a unique opportunity to improve our global un-derstanding of the earliest phases of star formation. I will present an overview of the first results from the Gould Belt survey (cf. http://gouldbelt-herschel.cea.fr/), one of the largest key projects with Herschel. The immediate objective of this SPIRE/PACS imaging survey is to obtain complete samples of nearby prestellar cores and Class 0 protostars with well char-acterized luminosities, temperatures, and density profiles, as well as robust core mass func-tions and protostar luminosity functions, in a variety of star-forming environments. Thanks to its high sensitivity and large spatial dynamic range, this survey can also probe, for the first time, the link between diffuse cirrus-like structures and compact self-gravitating cores. The main scientific goal is to elucidate the physical mechanisms responsible for the formation of prestellar cores out of the diffuse interstellar medium, crucial for understanding the origin of the stellar initial mass function. The first results, obtained toward the Aquila Rift and Polaris Flare regions during the 'Science Demonstration Phase' (SDP), are very promising (cf. http://herschel.esac.esa.int/SDPw kshops/presentations/IR/25A ndreG ouldBeltS DP 2009.pdf ).Basedonth

Direct Detection of Trivelpiece-Gould Modes in Helicon Discharges  

NASA Astrophysics Data System (ADS)

It has been suggested^1 that Trivelpiece-Gould (TG) modes near the plasma surface are essential for the absorption of rf energy in helicon (H) discharges. At high fields B_0, TG modes are damped in a thin layer and are difficult to resolve with probes. At low B_0, however, TG modes have longer radial wavelengths and interfere with the H waves, changing the radial wave amplitude profiles. This change was barely detectable when the wave Bz was measured with B-dot probes. However, theory suggests that the current Jz would emphasize the TG mode over the H mode by a factor ? _TG/? _H. We have constructed and carefully calibrated an rf J-dot probe to measure the Jz profiles. Measurements were made in a narrow window of n-B0 space where the coupled H-TG wave has a distinctive profile AND have ? _TG/? H > 2. The Jz profiles clearly show the secondary amplitude peaks due to the TG mode, in agreement with numerical calculations. ^1 D. Arnush, Phys. Plasmas 7, 3042 (2000).

Pathogenicity of Haemoproteus danilewskyi, Kruse, 1890, in blue jays (Cyanocitta cristata).

Although the impact of blood parasite infections on passerine birds is potentially great, little is known of their pathologic effects. We studied Haemoproteus danilewskyi in experimentally infected captive and naturally infected free-ranging blue jays (Cyanocitta cristata) to determine patterns of infection and examine the pathologic effects of the parasite on the host. Physiologic changes, such as elevated numbers of lymphocytes, heterophils, basophils, eosinophils, and monocytes and decreased packed cell volume in the peripheral blood were associated with the erythrocytic phase of experimental infections of captive juvenile jays. Sublethal pathologic changes associated with the pre-erythrocytic phase of infections were observed in the liver, lung, and spleen. Schizonts were observed in the pulmonary capillaries of a 1 yr old jay necropsied 31 days post-inoculation, but not in 20 juvenile jays necropsied 57 days post-inoculation. In free-ranging naturally infected jays plasma protein concentration increased with density of natural infections. PMID:12685080

New Burgess shale type fauna in the Middle Cambrian Stephen Formation on Mt. Stephen, British Columbia  

SciTech Connect

Excavation of a fossil locality discovered in 1981 on Mount Stephen, 5 km south of the Burgess shale site on Mount Wapta, has yielded about 1000 specimens of a new soft-bodied and lightly-sclerotized fauna. The fauna includes the trilobite, Glossopleura, which is characteristic of the lower part of the Stephen Formation, 100 m or more stratigraphically below the level of the Burgess shale fauna. The arthropod, Alalcomenaeus, a genus extremely rare in the Burgess shale, is by far the most numerous, followed by a new, fishlike arthropod with prominent eyes, and Branchiocaris, another extremely rare Burgess shale arthropod. Many Burgess shale animals are present, although the most common, Marrella, is absent. They include the arthropods Canadaspis, Naraoia, Plenocaris and Tuzoia, the worms Ottoia and Burgessochaeta, the onychophoran Aysheaia, the sponge Leptomitus, Wiwaxia of unknown affinities, and Fasciculus, a possible ctenophore. The Glossopleura fauna thus adds extant and extinct invertebrate groups to those already known in the Middle Cambrian epoch, mostly from the Burgess shale. It also demonstrates that the animals preserved in the Stephen Formation are evolutionarily stable.

Careful cachers and prying pilferers: Eurasian jays (Garrulus glandarius) limit auditory information available to competitors.  

PubMed

Food-storing corvids use many cache-protection and pilfering strategies. We tested whether Eurasian jays (Garrulus glandarius) reduce the transfer of auditory information to a competitor when caching and pilfering. We gave jays a noisy and a quiet substrate to cache in. Compared with when alone, birds cached less in the noisy substrate when with a conspecific that could hear but could not see them caching. By contrast, jays did not change the amount cached in the noisy substrate when they were with a competitor that could see and hear them caching compared with when they were alone. Together, these results suggest that jays reduce auditory information during caching as a cache-protection strategy. By contrast, as pilferers, jays did not attempt to conceal their presence from a cacher and did not prefer a silent viewing perch over a noisy one when observing caching. However, birds vocalized less when watching caching compared with when they were alone, when they were watching a non-caching conspecific or when they were watching their own caches being pilfered. Pilfering jays may therefore attempt to suppress some types of auditory information. Our results raise the possibility that jays both understand and can attribute auditory perception to another individual. PMID:23222444

Stephen's Guide to the Logical Fallacies  

NSDL National Science Digital Library

Stephen Downes, an information architect with a background in philosophy, created this site with the aim of identifying, indexing, and describing "all known logical fallacies." A logical fallacy can be defined as an error in reasoning in which a conclusion appears to follow from a set of premises but in reality does not. Downes groups the fallacies into thirteen categories, such as Fallacies of Distraction, Inductive Fallacies, and Syllogistic Errors. Each fallacy (over 50 in all) is described with its name, definition, examples of how it might be used in an argument, and how the argument can be proven fallacious. The How to Use this Guide section of the site provides a helpful introduction, and a robust bibliography offers possibilities for further study of logic. In addition, users may register at the site (no fee) to gain access to discussion boards on the topic. The author notes that his Guide "is intended to help you in your own thinking, not to help you demolish someone else's argument." Regardless of how a reader uses the information, however, the site remains an interesting and fun investigation of how logical arguments are constructed.

Re-caching by Western Scrub-Jays (Aphelocoma californica) Cannot Be Attributed to Stress  

PubMed Central

Western scrub-jays (Aphelocoma californica) live double lives, storing food for the future while raiding the stores of other birds. One tactic scrub-jays employ to protect stores is “re-caching”—relocating caches out of sight of would-be thieves. Recent computational modelling work suggests that re-caching might be mediated not by complex cognition, but by a combination of memory failure and stress. The “Stress Model” asserts that re-caching is a manifestation of a general drive to cache, rather than a desire to protect existing stores. Here, we present evidence strongly contradicting the central assumption of these models: that stress drives caching, irrespective of social context. In Experiment (i), we replicate the finding that scrub-jays preferentially relocate food they were watched hiding. In Experiment (ii) we find no evidence that stress increases caching. In light of our results, we argue that the Stress Model cannot account for scrub-jay re-caching.

Thoughts after reading Robert Jay Lifton's 'The Nazi Doctors'.  

PubMed

Robert Jay Lifton's remarkable book The Nazi Doctors and its tragic subject matter provided an opportunity to try and place the complicity of doctors in such barbarity in historical perspective. Massive episodes of killing of human beings by other human beings have been an ongoing saga for centuries. Misguided belief and misguided science, and the abuse of constantly advancing technology in the name of one or other nation-state, have made possible the acceleration of megadeath. The Nazi concentration and death camps were a particularly vicious manifestation within the spectrum of killing. Modern weaponry makes omnicide quite feasible. Our urgent need is to learn the lesson and to cultivate and promote planetary patriotism as promptly as possible. Adherence to an international code of human ethics is a compelling requirement. The origin of the International Committee of the Red Cross in 1863 was an inspiring and promising beginning. The formulation of the Declaration of Geneva by the World Medical Association in 1947 profoundly enhanced the value of the Hippocratic Oath and provides a sound ethical basis for the national and international guidance of the medical profession today. The International Physicians for the Prevention of Nuclear War establishes another firm step in the right direction. PMID:2695805

Stephen Jay Gould presented his position on science and religion - Non-Overlapping Magisteria (NOMA) - without justification. A detailed justification of the NOMA position can be found in the earlier work of scientist and philosopher Yishayahu Leibowitz; his work is especially interesting because it comes from a religious person. This paper summarizes Leibowitz's philosophical and theological position, and claims that his version of NOMA, and by implication similar versions of NOMA, are not applicable in science education.

Contrasting genetic structures in sister species of North American scrub-jays  

PubMed Central

Threatened Florida scrub-jays (Aphelocoma coerulescens breed communally, are restricted to xeric sandy scrub habitat, generally disperse fewer than three territory diameters. Closely related Western scrub-jays (A. californica) do not breed communally, have a broader habitat range, disperse greater distances, and are not threatened. We compared the genetic structure of 445 individuals in 11 populations in Florida with 157 individuals in eight populations of Western scrub-jays. At ten microsatellite loci, Florida had 24 out of 47 total alleles, while Western scrub-jays had 44. The Florida populations were more differentiated (GST = 0.048) than were a set of five California populations (GST = 0.015). A randomization extension of a Mantel test showed a stronger correlation between geographic and Cavalli-Sforza genetic distances among Western than Florida populations. Neighbour-joining trees clustered Florida populations from the same sandy ridge systems, suggesting that habitat continuity is more important than geographic proximity in allowing gene flow and preventing differentiation. For Western populations, isolation by distance appears to be the major determinant of genetic structure. Our results suggest that contrasting genetic structures may arise between closely related species, as a result of differences in ecology and social system. Conserving extant genetic variation in Florida jays will require maintaining viable populations in each of the major sandy ridge systems.

Interacting Cache memories: evidence for flexible memory use by Western Scrub-Jays (Aphelocoma californica).  

PubMed

When Western Scrub-Jays (Aphelocoma californica) cached and recovered perishable crickets, N. S. Clayton, K. S. Yu, and A. Dickinson (2001) reported that the jays rapidly learned to search for fresh crickets after a 1-day retention interval (RI) between caching and recovery but to avoid searching for perished crickets after a 4-day RI. In the present experiments, the jays generalized their search preference for crickets to intermediate RIs and used novel information about the rate of decay of crickets presented during the RI to reverse these search preferences at recovery. The authors interpret this reversal as evidence that the birds can integrate information about the caching episode with new information presented during the RI. PMID:12561130

Does multiple seed loading in Blue Jays result in selective dispersal of smaller acorns?  

PubMed

Studies from both tropical and temperate systems show that scatter-hoarding rodents selectively disperse larger seeds farther from their source than smaller seeds, potentially increasing seedling establishment in larger-seeded plants. Size-biased dispersal is evident in many oaks (Quercus) and is true both across and within species. Here, we predict that intraspecifc variation in seed size also influences acorn dispersal by the Blue Jay (Cyanocitta cristata Linnaeus), but in an opposite manner. Blue Jays are gape-limited and selectively disperse smaller acorn species (e.g. pin oaks [Quercus palustris Münchh]), but often carry several acorns in their crop during a single dispersal event. We predict that jays foraging on smaller acorns will load more seeds per trip and disperse seeds to greater distances than when single acorns are carried in the bill. To test this, we presented free-ranging Blue Jays with pin oak acorns of different sizes over a 2-year period. In each of 16 experimental trials, we monitored the birds at a feeding station with remote cameras and determined the number of acorns removed and the distance acorns were dispersed when cached. Jays were significantly more likely to engage in multiple seed loading with smaller seeds in both years of the study. During the second year, these smaller acorns were dispersed farther than larger acorns, and during the first year, larger acorns were dispersed farther, revealing an inconsistent response to seed size during our study. We suggest that in some circumstances, multiple seed loading by Blue Jays may favor dispersal in some plant species. PMID:21910843

A review of the experience gained in 10 years operation of Gould's solar industrial process heat system  

NASA Astrophysics Data System (ADS)

For nearly 10 years, the Gould Electronics, Incorporated manufacturing plant in Chandler, Arizona, has been a model of how medium-temperature solar thermal energy systems can produce economical industrial process heat (IPH). In 1982, a solar IPH system was designed and built on the site by Solar Kinetics, Inc. The system has remained in operation and continues to provide economical process heat for Gould's copper foil manufacturing operation. System performance and availability has fluctuated over the years, reaching a low point in early 1990 when the system was nearly inoperative because of equipment reliability problems. Gould teamed with engineers from Sandia National Laboratories' (Sandia) Solar Thermal Design Assistance Center to develop a plan to solve the technical problems and refurbish the field. The IPH system is currently operating at over 90-percent equipment availability, returning to Gould a net energy cost savings on the order of $7,500 per month. This paper presents the history and operation of the system from the perspective of the end user and describes the phased upgrade program undertaken with Sandia to refurbish the system.

Propagation of axisymmetric Trivelpiece-Gould mode along vortex columns generated by diocotron instability  

SciTech Connect

A high-frequency (HF) oscillation has been observed to propagate along magnetic field lines with an axisymmetric profile extending over multiple columns of magnetized pure electron plasma which undergo two-dimensional vortex motions. The observed frequency is a few hundred times higher than the rotation frequency of the vortices and varies in time as the density distribution of electrons deforms from an unstable hollow profile into vortex columns and approaches a single-peaked distribution. Experimental examinations reveal that the HF oscillation is excited by the gate pulse applied to prepare the initial profile and that the oscillation does not influence the subsequent dynamics of vortex columns. Further examinations including detailed observations and theoretical analyses indicate that the HF oscillation represents a profile-dependent eigenfunction of the Trivelpiece-Gould mode wave that consists of a dominant axisymmetric component and small fractions of higher azimuthal modes associated with the density distribution separated into columns.

Habitat-specific breeder survival of Florida Scrub-Jays: inferences from multistate models.  

PubMed

Quantifying habitat-specific survival and changes in habitat quality within disturbance-prone habitats is critical for understanding population dynamics and variation in fitness, and for managing degraded ecosystems. We used 18 years of color-banding data and multistate capture-recapture models to test whether habitat quality within territories influences survival and detection probability of breeding Florida Scrub-Jays (Aphelocoma coerulescens) and to estimate bird transition probabilities from one territory quality state to another. Our study sites were along central Florida's Atlantic coast and included two of the four largest metapopulations within the species range. We developed Markov models for habitat transitions and compared these to bird transition probabilities. Florida Scrub-Jay detection probabilities ranged from 0.88 in the tall territory state to 0.99 in the optimal state; detection probabilities were intermediate in the short state. Transition probabilities were similar for birds and habitat in grid cells mapped independently of birds. Thus, bird transitions resulted primarily from habitat transitions between states over time and not from bird movement. Survival ranged from 0.71 in the short state to 0.82 in the optimal state, with tall states being intermediate. We conclude that average Florida Scrub-Jay survival will remain at levels that lead to continued population declines because most current habitat quality is only marginally suitable across most of the species range. Improvements in habitat are likely to be slow and difficult because tall states are resistant to change and the optimal state represents an intermediate transitional stage. The multistate modeling approach to quantifying survival and habitat transition probabilities is useful for quantifying habitat transition probabilities and comparing them to bird transition probabilities to test for habitat selection in dynamic environments.

Concomitant mycotic and verminous pneumonia in a blue jay from Georgia.  

PubMed

An emaciated, moribund, male blue jay (Cyanocitta cristata) was collected in Georgia (USA) and died shortly after capture. Necropsy revealed nine large nematodes identified as Diplotriaena tricuspis in the thoracic and abdominal air sacs and within the pericardial sac. Multiple mycotic granulomas also were observed in the lungs and air sacs, and fungal culture of these lesions yielded pure growth of Aspergillus fumigatus. Histologic examination of the lungs revealed disseminated granulomatous inflammation containing both larvated nematode eggs and abundant fungal hyphae. This is the first description of concomitant A. fumigatus and D. tricuspis infection in a bird. PMID:9706574

Western scrub-jays (Aphelocoma californica) have been shown to overcome present satiety to cache food they will desire in the future. Here, we show that another corvid, the Eurasian jay (Garrulus glandarius), can distinguish between two distinct future desires and plan for each appropriately, despite experiencing a conflicting current motivation. We argue that these data address the criticisms of previous work, and suggest a way in which associative learning processes and future-oriented cognition may combine to allow prospective behaviour.

Historical biogeography and speciation in the neotropical highlands: molecular phylogenetics of the jay genus Cyanolyca.  

PubMed

Phylogenetic relationships were studied in the genus Cyanolyca, an assemblage of jays distributed from Mexico south to Bolivia. Given its fragmented distribution along the humid forests of the Neotropics, the genus Cyanolyca is a model group for exploring hypotheses on biogeography and speciation. Phylogenetic analyses were based on two mitochondrial and three nuclear loci; taxon sampling includes all species in the genus and most subspecies. Maximum parsimony, maximum likelihood, and Bayesian analyses produced trees that were congruent and highly robust at both terminal and deep nodes of the phylogeny. Cyanolyca comprises two major clades: one contains the Mesoamerican "dwarf" jays, and the other consists of two main groups--C. cucullata+C. pulchra and the "core" South American species. Prior hypotheses of relationships were explored statistically using Maximum Likelihood and Bayesian approaches. Dispersal-Vicariance analysis revealed the importance of the Northern Andes as a major center for biological diversification, and the effects of dispersal across the Panamanian Land Bridge in the composition of South American and Mesoamerican avifaunas. Phylogenetic patterns are highly congruent with an allopatric mode of speciation. Implications of these results are discussed in the context of the biogeography of Neotropical montane forests.

Neurogenesis in the mossy chiton, Mopalia muscosa (Gould) (Polyplacophora): evidence against molluscan metamerism.  

PubMed

Neurogenesis in the chiton Mopalia muscosa (Gould, 1846) was investigated by applying differential interference contrast microscopy, semithin serial sectioning combined with reconstruction techniques, as well as confocal laser scanning microscopy for the detection of fluorescence-conjugated antibodies against serotonin and FMRFamide. The ontogeny of serotonergic nervous structures starts with cells of the apical organ followed by those of the cerebral commissure, whereas the serotonergic prototroch innervation, pedal system, and the lateral cords develop later. In addition, there are eight symmetrically arranged serotonergic sensory cells in the dorsal pretrochal area of the larva. FMRFamide-positive neural elements include the cerebral commissure, specific "ampullary" sensory cells in the pretrochal region, as well as the larval lateral and pedal system. In the early juvenile the cerebral system no longer stains with either of the two antibodies and the pedal system lacks anti-FMRFamide immunoreactivity. Outgroup comparison with all other molluscan classes and related phyla suggests that the cord-like, nonganglionized cerebral system in the Polyplacophora is a reduced condition rather than a primitive molluscan condition. The immunosensitivity of the pedal commissures develops from posterior to anterior, suggesting independent serial repetition rather than annelid-like conditions and there is no trace of true segmentation during nervous system development. Polyplacophoran neurogenesis and all other available data on the subject contradict the idea of a segmented molluscan stem species. PMID:12112126

Who Invented the Word Asteroid: William Herschel or Stephen Weston?

William Herschel made the first serious study of 1 Ceres and 2 Pallas in the year 1802. He was moved by their dissimilarities to the other planets to coin a new term to distinguish them. For this purpose he enlisted the aid of his good friends William Watson and Sir Joseph Banks. Watson gave him a long list of possible names, most of which sound quite ludicrous. With a lifetime of experience classifying and naming newly found objects in nature, Banks became the man both Erasmus Darwin (in 1781) and William Herschel (in 1802) turned to for sage advice in developing a new descriptive language. In the case of Ceres and Pallas, Banks turned the task over to his friend, the noted philologist Stephen Weston FRS. It has recently been stated by a noted British historian that it was Weston- not Herschel- who coined the term "asteroid" to collectively describe Ceres and Pallas. This claim is investigated, and parallels are drawn in the use of neologism in astronomy and botany.

Efficacy of Three Vaccines in Protecting Western Scrub-Jays (Aphelocoma californica) from Experimental Infection with West Nile Virus: Implications for Vaccination of Island Scrub-Jays (Aphelocoma insularis)  

PubMed Central

Abstract The devastating effect of West Nile virus (WNV) on the avifauna of North America has led zoo managers and conservationists to attempt to protect vulnerable species through vaccination. The Island Scrub-Jay (Aphelocoma insularis) is one such species, being a corvid with a highly restricted insular range. Herein, we used congeneric Western Scrub-Jays (Aphelocoma californica) to test the efficacy of three WNV vaccines in protecting jays from an experimental challenge with WNV: (1) the Fort Dodge West Nile-Innovator® DNA equine vaccine, (2) an experimental DNA plasmid vaccine, pCBWN, and (3) the Merial Recombitek® equine vaccine. Vaccine efficacy after challenge was compared with naïve and nonvaccinated positive controls and a group of naturally immune jays. Overall, vaccination lowered peak viremia compared with nonvaccinated positive controls, but some WNV-related pathology persisted and the viremia was sufficient to possibly infect susceptible vector mosquitoes. The Fort Dodge West Nile-Innovator DNA equine vaccine and the pCBWN vaccine provided humoral immune priming and limited side effects. Five of the six birds vaccinated with the Merial Recombitek vaccine, including a vaccinated, non-WNV challenged control, developed extensive necrotic lesions in the pectoral muscle at the vaccine inoculation sites, which were attributed to the Merial vaccine. In light of the well-documented devastating effects of high morbidity and mortality associated with WNV infection in corvids, vaccination of Island Scrub-Jays with either the Fort Dodge West Nile-Innovator DNA vaccine or the pCBWN vaccine may increase the numbers of birds that would survive an epizootic should WNV become established on Santa Cruz Island.

Patterns of West Nile virus infection in Ohio blue jays: implications for initiation of the annual cycle.  

PubMed

West Nile virus (WNV) was first detected in North America in New York City in 1999 and rapidly moved westward. Understanding the mechanisms by which the amplification cycle is reinitiated each year increases our ability to predict epizootics and geographic expansion of the disease. Such understanding is enhanced by knowledge of the patterns of infection in the vertebrate reservoir hosts. Blue jays (Cyanocitta cristata) may serve as reservoir hosts for WNV. We examined the influence of age and date on the prevalence of WNV in jay carcasses in Ohio during May-August 2002. Percent of carcasses that were infected increased significantly with time from 3% in May to more than 90% by August. We found no difference in prevalence between juvenile (nestlings and fledglings) and adult jays early in the season, which contradicts the expected pattern if the majority of the adults sampled in 2002 had been exposed to the virus in 2001. Therefore, jays infected in 2001 were unlikely to have been important in initiating the 2002 virus cycle in Ohio. PMID:15155993

The effects of low levels of light at night upon the endocrine physiology of western scrub-jays (Aphelocoma californica).  

PubMed

Florida scrub-jays (Aphelocoma coerulescens) in the suburbs breed earlier than jays in native habitat. Amongst the possible factors that influence this advance (e.g., food availability, microclimate, predator regime, etc.), is exposure to artificial lights at night (LAN). LAN could stimulate the reproductive axis of the suburban jays. Alternatively, LAN could inhibit pineal melatonin (MEL), thus removing its inhibitory influence on the reproductive axis. Because Florida scrub-jays are a threatened species, we used western scrub-jays (Aphelocoma californica) to investigate the effects of LAN upon reproductive hormones and melatonin. Jays were held under conditions in which the dark-phase of the light:dark cycle was without illumination and then under low levels of LAN. Under both conditions, birds were exposed first to short-days (9.5L:14.5D) that were gradually increased to long-days (14.5L:9.5D). At various times, blood samples were collected during the light part of the cycle to measure reproductive hormones (luteinizing hormone, LH; testosterone, T; and estradiol, E2 ). Similarly, samples to assess melatonin were collected during the dark. In males, LAN caused a depression in LH levels and levels were ?4× greater under long- than short-days. In females, there was no effect of LAN or photoperiod upon LH. LAN resulted in depressed T levels in females, although there was no effect on T in males. E2 levels in both sexes were lower under LAN than under an unlighted dark-phase. Paradoxically, MEL was higher in jays under LAN, and under long-days. MEL did not differ by sex. LAN disrupted the extraordinarily strong correlation between T and E2 that existed under unlighted nocturnal conditions. Overall, our findings fail to support the hypothesis that LAN stimulates the reproductive axis. Rather, the data demonstrate that LAN tends to inhibit reproductive hormone secretion, although not in a consistent fashion between the sexes. J. Exp.

Increased lifetime reproductive success for Siberian jay (Perisoreus infaustus) males with delayed dispersal  

PubMed Central

In a crowded environment the natal territory could serve as a haven for young and inexperienced offspring until a breeding vacancy emerges. Delayed dispersal and association with kin could then offer adaptive benefits through an individual fitness gain. Here we report that delayed dispersal is associated with a higher lifetime individual fitness in Siberian jay (Perisoreus infaustus) males. Sons bred more successfully and had more reproductive events in life when they delayed dispersal. The higher lifetime reproductive success when sons disperse later in life is sufficient to promote postponement of natal dispersal, suggesting that dispersal is delayed due to ecological constraints on access to high-quality habitats. We argue that the maintenance of this variation in the timing of dispersal and reproductive success can be reconciled with non-genetic mechanisms driving dispersal. Social dominance within broods reflecting environmental conditions during growth is such a mechanism.

The Effect of Modified Brostrom-Gould Repair for Lateral Ankle Instability on In Vivo Tibiotalar Kinematics  

PubMed Central

Background Lateral ankle instability leads to an increased risk of tibiotalar joint osteoarthritis. Previous studies have found abnormal tibiotalar joint motions with lateral ankle instability that may contribute to this increased incidence of osteoarthritis, including increased anterior translation and internal rotation of the talus under weight-bearing loading. Surgical repairs for lateral ankle instability have shown good clinical results, but the effects of repair on in vivo ankle motion are not well understood. Hypothesis The modified Broström-Gould lateral ligament reconstruction decreases anterior translation and internal rotation of the talus under in vivo weight-bearing loading conditions. Study Design Controlled laboratory study. Methods Seven patients underwent modified Brostöm-Gould repair for unilateral lateral ankle instability. Ankle joint kinematics as a function of increasing body weight were studied with magnetic resonance imaging and biplanar fluoroscopy. Tibiotalar kinematics were measured in unstable ankles preoperatively and postoperatively at a mean follow-up of 12 months, as well as in the uninjured contralateral ankles of the same individuals. Results Surgical repair resulted in statistically significant decreases in anterior translation of the talus (0.9±0.3mm, p=0.018) at 100% bodyweight and internal rotation of the talus at 75% (2.6±0.8°, p=0.019) and 100% (2.7±0.8°, p=0.013) bodyweight compared to ankle kinematics measured before repair. No statistically significant differences were detected between repaired ankles and contralateral normal ankles. Conclusion The modified Broström-Gould repair improved the abnormal joint motion observed in patients with lateral ankle instability, decreasing anterior translation and internal rotation of the talus. Clinical Relevance Altered kinematics may contribute to the tibiotalar joint degeneration that occurs with chronic lateral ankle instability. The findings of the current study support the efficacy of this repair in improving the abnormal ankle motion observed in these patients.

The Frenkel Kontorova Model

In the preface to his monograph on the structure of Evolutionary Theory [1], the late professor Stephen Jay Gould attributes to the philosopher Immanuel Kant the following aphorism in Science Philosophy: "Percepts without concepts are blind; concepts without percepts are empty". Using with a bit of freedom these Kantian terms, one would say that a scientific model is a framework (or network) of interrelated concepts and percepts where experts build up scientific consistent explanations of a given set of observations. Good models are those which are both, conceptually simple and universal in their perceptions. Let us illustrate with examples the meaning of this statement.

Dynamics and phylogenetic implications of MtDNA control region sequences in New World Jays (Aves: Corvidae).  

PubMed

To study the evolution of mtDNA and the intergeneric relationships of New World Jays (Aves: Corvidae), we sequenced the entire mitochondrial DNA control region (CR) from 21 species representing all genera of New World jays, an Old World jay, crows, and a magpie. Using maximum likelihood methods, we found that both the transition/transversion ratio (kappa) and among site rate variation (alpha) were higher in flanking domains I and II than in the conserved central domain and that the frequency of indels was highest in domain II. Estimates of kappa and alpha were much more influenced by the density of taxon sampling than by alternative optimal tree topologies. We implemented a successive approximation method incorporating these parameters into phylogenetic analysis. In addition we compared our study in detail to a previous study using cytochrome b and morphology to examine the effect of taxon sampling, evolutionary rates of genes, and combined data on tree resolution. We found that the particular weighting scheme used had no effect on tree topology and little effect on tree robustness. Taxon sampling had a significant effect on tree robustness but little effect on the topology of the best tree. The CR data set differed nonsignificantly from the tree derived from the cytochrome b/morphological data set primarily in the placement of the genus Gymnorhinus, which is near the base of the CR tree. However, contrary to conventional taxonomy, the CR data set suggested that blue and black jays (Cyanocorax sensu lato) might be paraphyletic and that the brown jay Psilorhinus (=Cyanocorax) morio is the sister group to magpie jays (Calocitta), a phylogenetic hypothesis that is likely as parsimonious with regard to nonmolecular characters as monophyly of Cyanocorax. The CR tree also suggests that the common ancestor of NWJs was likely a cooperative breeder. Consistent with recent systematic theory, our data suggest that DNA sequences with high substitution rates such as the CR may nonetheless be useful in reconstructing relatively deep phylogenetic nodes in avian groups.

Mind the gap: genetic distance increases with habitat gap size in Florida scrub jays.  

PubMed

Habitat gap size has been negatively linked to movement probability in several species occupying fragmented landscapes. How these effects on movement behaviour in turn affect the genetic structure of fragmented populations at local scales is less well known. We tested, and confirmed, the hypothesis that genetic differentiation among adjacent populations of Florida scrub jays--an endangered bird species with poor dispersal abilities and a high degree of habitat specialization--increases with the width of habitat gaps separating them. This relationship was not an artefact of simple isolation-by-distance, as genetic distance was not correlated with the Euclidean distance between geographical centroids of the adjacent populations. Our results suggest that gap size affects movement behaviour even at remarkably local spatial scales, producing direct consequences on the genetic structure of fragmented populations. This finding shows that conserving genetic continuity for specialist species within fragmented habitat requires maintenance or restoration of preserve networks in which habitat gaps do not exceed a species-specific threshold distance.

Evidence suggesting that desire-state attribution may govern food sharing in Eurasian jays  

PubMed Central

State-attribution is the ability to ascribe to others an internal life like one’s own and to understand that internal, psychological states such as desire, hope, belief, and knowledge underlie others’ actions. Despite extensive research, comparative studies struggle to adequately integrate key factors of state-attribution that have been identified by evolutionary and developmental psychology as well as research on empathy. Here, we develop a behavioral paradigm to address these issues and investigate whether male Eurasian jays respond to the changing desire-state of their female partners when sharing food. We demonstrate that males feed their mates flexibly according to the female’s current food preference. Critically, we show that the males need to see what the female has previously eaten to know what food she will currently want. Consequently, the males’ sharing pattern was not simply a response to their mate’s behavior indicating her preference as to what he should share, nor was it a response to the males’ own desire-state. Our results raise the possibility that these birds may be capable of ascribing desire to their mates.

Signaling for food and sex? Begging by reproductive female white-throated magpie-jays  

PubMed Central

Food begging is common in nutritionally dependent young of many animals, but structurally homologous calls recur in adult signal repertoires of many species. We propose eight functional hypotheses for begging in adults; these stem from observations in birds but apply broadly to other taxa in which begging occurs. Adult cooperatively-breeding white-throated magpie-jays (Calocitta formosa) use loud begging vocalizations, particularly near the nest site during reproduction. We analysed the social context and behavioural phenology of loud calling and allofeeding in this species and compared these with predictions from each functional hypothesis. We found that reproductive females are the primary producers of beg calls, and their begging peaks during the fertile period when reproductive conflict among males and females was highest. Loud begging rates correlated positively with provisioning rates, but females called more in the pre-incubation fertile period than after they initiated incubation. Based on the context, phenology and active space of the signal, we conclude that female loud begging vocalizations function to signal nutritional need to group members, but also have been evolutionarily co-opted to advertise fertility to potential extra-pair partners. The location of calling is likely a consequence of nest guarding by breeding females to prevent intraspecific brood parasitism.

Using data on breeding birds from a 35-year study of Florida scrub-jays Aphelocoma coerulescens (Bosc 1795), we show that survival probabilities are structured by age, birth cohort, and maternal family, but not by sex. Using both accelerated failure time (AFT) and Cox proportional hazard models, the data are best described by models incorporating variation among birth cohorts and greater mortality hazard with increasing age. AFT models using Weibull distributions with the shape parameter > 1 were always the best-fitting models. 2. Shared frailty models allowing for family structure greatly reduce model deviance. The best-fitting models included a term for frailty shared by maternal families. 3. To ask how long a data set must be to reach qualitatively the same conclusions, we repeated the analyses for all possible truncated data sets of 2 years in length or greater. Length of the data set affects the parameter estimates, but not the qualitative conclusions. In all but three of 337 truncated data sets the best-fitting models pointed to same conclusions as the full data set. Shared frailty models appear to be quite robust. 4. The data are not adequate for testing hypotheses as to whether variation in frailty is heritable. 5. Substantial structured heterogeneity for survival exists in this population. Such structured heterogeneity has been shown to have substantial effects in reducing demographic stochasticity. PMID:17009755

Calibrating divergence times on species trees versus gene trees: implications for speciation history of Aphelocoma jays.  

PubMed

Estimates of the timing of divergence are central to testing the underlying causes of speciation. Relaxed molecular clocks and fossil calibration have improved these estimates; however, these advances are implemented in the context of gene trees, which can overestimate divergence times. Here we couple recent innovations for dating speciation events with the analytical power of species trees, where multilocus data are considered in a coalescent context. Divergence times are estimated in the bird genus Aphelocoma to test whether speciation in these jays coincided with mountain uplift or glacial cycles. Gene trees and species trees show general agreement that diversification began in the Miocene amid mountain uplift. However, dates from the multilocus species tree are more recent, occurring predominately in the Pleistocene, consistent with theory that divergence times can be significantly overestimated with gene-tree based approaches that do not correct for genetic divergence that predates speciation. In addition to coalescent stochasticity, Haldane's rule could account for some differences in timing estimates between mitochondrial DNA and nuclear genes. By incorporating a fossil calibration applied to the species tree, in addition to the process of gene lineage coalescence, the present approach provides a more biologically realistic framework for dating speciation events, and hence for testing the links between diversification and specific biogeographic and geologic events.

Nutritional quality of prebreeding diet influences breeding performance of the Florida scrub-jay.  

PubMed

Food supplementation studies of breeding birds have traditionally concentrated on energetic constraints on breeding performance. It is only recently that the nutritional quality of the prebreeding diet has also been considered influential. We examined the importance of specific nutrients in the prebreeding diet of the Florida scrub-jay ( Aphelocoma coerulescens). Birds were provided with one of two supplements (rich in protein and fat or rich in fat only) prior to breeding in 2000 and 2001 and their breeding performance, in relation to unsupplemented (control) birds, was examined. Birds receiving both supplements significantly advanced laying in both years, and increased clutch size in 2000 but not in 2001. Laying date explained variation in clutch size in birds on dietary supplements. Egg mass and volume declined with laying order, irrespective of dietary treatment, but birds on the high fat, high protein diet laid heavier third eggs than controls and this was independent of laying date. Laboratory analysis of 14 abandoned and unhatched eggs revealed that as egg mass increased so did the absolute amount of protein and water while fat content remained relatively fixed. Using these relationships between the masses of egg components and fresh egg mass, we calculated that heavier third eggs laid by birds on high fat and high protein, compared with those laid by controls, contained more water that may be fundamental to chick growth and survival. This is the first demonstration for an avian species that nutritional quality of prebreeding diet can simultaneously influence laying date, clutch size, and egg size and composition. PMID:12647137

THE SPITZER SURVEY OF INTERSTELLAR CLOUDS IN THE GOULD BELT. IV. LUPUS V AND VI OBSERVED WITH IRAC AND MIPS  

SciTech Connect

We present Gould's Belt (GB) Spitzer IRAC and MIPS observations of the Lupus V and VI clouds and discuss them in combination with near-infrared (2MASS) data. Our observations complement those obtained for other Lupus clouds within the frame of the Spitzer 'Core to Disk' (c2d) Legacy Survey. We found 43 young stellar object (YSO) candidates in Lupus V and 45 in Lupus VI, including two transition disks, using the standard c2d/GB selection method. None of these sources was classified as a pre-main-sequence star from previous optical, near-IR, and X-ray surveys. A large majority of these YSO candidates appear to be surrounded by thin disks (Class III; {approx}79% in Lupus V and {approx}87% in Lupus VI). These Class III abundances differ significantly from those observed for the other Lupus clouds and c2d/GB surveyed star-forming regions, where objects with optically thick disks (Class II) dominate the young population. We investigate various scenarios that can explain this discrepancy. In particular, we show that disk photoevaporation due to nearby OB stars is not responsible for the high fraction of Class III objects. The gas surface densities measured for Lupus V and VI lie below the star formation threshold (A{sub V} {approx} 8.6 mag), while this is not the case for other Lupus clouds. Thus, few Myr older age for the YSOs in Lupus V and VI with respect to other Lupus clouds is the most likely explanation of the high fraction of Class III objects in these clouds, while a higher characteristic stellar mass might be a contributing factor. Better constraints on the age and binary fraction of the Lupus clouds might solve the puzzle but require further observations.

A Tribute to Stephen Schneider, and an Example of "Setting the Scientific Record Straight"  

NASA Astrophysics Data System (ADS)

Stephen Henry Schneider made a difference in our world. His science, his words, and his actions forever changed the way we think about human influences on climate. Stephen Schneider helped us to realize that we are not just innocent bystanders - we are now active agents of change in the climate system. This lecture has two parts. The first part provides a personal tribute to Steve Schneider. The second part addresses an issue that was of considerable concern to him - the issue of "setting the scientific record straight". As scientists, do we have the professional, ethical, and moral responsibility to respond to inaccurate Congressional testimony regarding the nature and causes of climate change? If so, what are appropriate response strategies? The specific example discussed here arises from a Congressional hearing held on May 20, 2010. At this hearing, one expert witness claimed that climate models are incapable of simulating the relatively muted warming we have observed over the past 10 years. This claim is demonstrably incorrect. Because of the pronounced effects of interannual noise on decadal trends, a multi-model ensemble of anthropogenically-forced simulations displays many 10-year periods with little warming. A single decade of observational temperature data is therefore inadequate for identifying a slowly evolving anthropogenic warming signal. As will be shown, knowledge of signal-to-noise behavior as a function of timescale is key to any meaningful discussion of the causes of recent temperature changes.

Significance of a basal melanin layer to production of non-iridescent structural plumage color: evidence from an amelanotic Steller's jay (Cyanocitta stelleri).  

PubMed

Non-iridescent structural plumage color is typically produced by coherent scattering of light within a matrix of keratin and air (a ;spongy layer') in feather barbs. It remains unclear what role, if any, the basal melanin layer underlying this spongy layer plays in the production of coloration. Amelanism in birds with structural color is a ;natural experiment' in which melanin pigmentation is lost, allowing us to identify the effects of the loss of melanin on structural color production. Here we use full-spectrum spectrometry, transmission electron microscopy and Fourier analysis to compare the color and nanostructure of an amelanotic Steller's jay (Cyanocitta stelleri Gmelin) feather with a normal blue Steller's jay feather. As a control, we also examined a white domestic chicken (Gallus gallus Linnaeus) feather. The pale amelanotic jay feather had a broad reflectance curve with a blue/green peak, while the typical blue feather had a typical distinct bell-shaped blue curve with a UV/violet peak. The white chicken feather had a typical white reflectance curve with no discrete peaks. Electron microscopy revealed that both the amelanotic and blue feather barbs contained well-formed spongy layers that were of the correct size and arrangement to produce their measured peak reflectance values, whereas the chicken feather had no spongy layer. The washed-out color of the amelanotic jay feather was thus most probably caused by the loss of the basal melanin layer, suggesting that melanin functions to absorb incoherently scattered white light from the feather barb thereby increasing the purity of the color produced by the spongy layer.

Probably Girard's most heroic gestures were his gallant fight against the yellow fever epidemic in 1793 and his loan to the U.S. government during the War of 1812, which allowed the bankrupt country to continue the conflict and ultimately to win the war.

The Development of Caching and Object Permanence in Western Scrub-Jays (Aphelocoma californica): Which Emerges First?  

PubMed Central

Recent studies on the food-caching behavior of corvids have revealed complex physical and social skills, yet little is known about the ontogeny of food caching in relation to the development of cognitive capacities. Piagetian object permanence is the understanding that objects continue to exist even when they are no longer visible. Here, the authors focus on Piagetian Stages 3 and 4, because they are hallmarks in the cognitive development of both young children and animals. Our aim is to determine in a food-caching corvid, the Western scrub-jay, whether (1) Piagetian Stage 4 competence and tentative caching (i.e., hiding an item invisibly and retrieving it without delay), emerge concomitantly or consecutively; (2) whether experiencing the reappearance of hidden objects enhances the timing of the appearance of object permanence; and (3) discuss how the development of object permanence is related to behavioral development and sensorimotor intelligence. Our findings suggest that object permanence Stage 4 emerges before tentative caching, and independent of environmental influences, but that once the birds have developed simple object-permanence, then social learning might advance the interval after which tentative caching commences.

Model study of St. Stephen powerhouse fish passage facilities, Cooper River rediversion project, South Carolina. Final report  

SciTech Connect

This report documents a model study of the St. Stephen Power Plant, located in Berkely County, South Carolina. A previous model study revealed that the fish lift at the powerhouse could be improved by providing auxiliary attraction flows to the fish entrances. An auxiliary attraction flow (AAF) system was proposed that uses a siphon to obtain the auxiliary attraction water from the reservoir. The model investigations reported herein address the flow conditions at the discharge end of the siphon; the hydraulic aspects of the siphon are not addressed. Three different models were used to evaluate flow conditions at the discharge end of the AAF system. A 1:25-scale model of the St. Stephen powerhouse was used to improve the fish entrance conditions and to evaluate the outlet conditions for the initial AAF system. As the investigations progressed, the design of the siphon discharge system was modified to include downstream fish migration and debris passage.

Abraham Lincoln loses a medical malpractice case, debates Stephen A. Douglas, and secures two murder acquittals.  

PubMed

An improperly healed fracture was the most common reason for the medical malpractice crisis between the 1830s and 1860s in the United States. As a practicing lawyer in Illinois, Abraham Lincoln defended physicians in medical malpractice law suits. One of these was Dr. Powers Ritchey, who was sued for malpractice in 1855. Lincoln agreed to represent Dr. Ritchey in 1858 as the case was appealed to the supreme court of Illinois. In the interim, Lincoln defended two indicted murderers and won acquittals for both. Between the two murder trials, Lincoln debated Stephen A. Douglas while running for U.S. Senator from Illinois. Lincoln believed that Ritchey's case was poorly represented in the lower court. Ritchey's prior attorneys did not file a bill of exceptions to the testimony of the plaintiff's expert medical witnesses. Lincoln attempted to rebut the allegation of a lack of reasonable medical care and diligence by Ritchey, and he sought to secure a new trial for his client. In its decision, the supreme court of Illinois did not find any error and affirmed the lower court's judgment. PMID:14768936

Influence of azadirachtin, a botanical insecticide, on Chrysoperla carnea (Stephens) reproduction: toxicity and ultrastructural approach.  

PubMed

A commercial formulation of azadirachtin (Align) was tested on Chrysoperla carnea (Stephens) (Neuroptera: Chrysopidae) adults to determine its effects on reproduction. Three methods of exposure were carried out in the laboratory (residual, direct contact and ingestion) with concentrations close to the maximum field recommended concentration in Spain (48 mg AI/liter). Align proved to be harmless to newly emerged adults irrespective of the mode of exposure. Nevertheless, fecundity was reduced in a reversible way in females that have ingested azadiracthin after the onset of oviposition. Fertility was not different from that of controls in all treatments. Additional tests showed that males were not involved in the reduction of oviposition. Electron microscopy studies pointed out that Align interfered with vitellogenin synthesis and/or its uptake by developing oocytes; thus, growing follicles in treated females were significantly smaller that those of the controls. The role of azadirachtin as a compound that may influence several hormonal and protein titers involved in reproduction is also discussed. PMID:14998126

Congruent population structure inferred from dispersal behaviour and intensive genetic surveys of the threatened Florida scrub-jay (Aphelocoma c??rulescens)  

USGS Publications Warehouse

The delimitation of populations, defined as groups of individuals linked by gene flow, is possible by the analysis of genetic markers and also by spatial models based on dispersal probabilities across a landscape. We combined these two complimentary methods to define the spatial pattern of genetic structure among remaining populations of the threatened Florida scrub-jay, a species for which dispersal ability is unusually well-characterized. The range-wide population was intensively censused in the 1990s, and a metapopulation model defined population boundaries based on predicted dispersal-mediated demographic connectivity. We subjected genotypes from more than 1000 individual jays screened at 20 microsatellite loci to two Bayesian clustering methods. We describe a consensus method for identifying common features across many replicated clustering runs. Ten genetically differentiated groups exist across the present-day range of the Florida scrub-jay. These groups are largely consistent with the dispersal-defined metapopulations, which assume very limited dispersal ability. Some genetic groups comprise more than one metapopulation, likely because these genetically similar metapopulations were sundered only recently by habitat alteration. The combined reconstructions of population structure based on genetics and dispersal-mediated demographic connectivity provide a robust depiction of the current genetic and demographic organization of this species, reflecting past and present levels of dispersal among occupied habitat patches. The differentiation of populations into 10 genetic groups adds urgency to management efforts aimed at preserving what remains of genetic variation in this dwindling species, by maintaining viable populations of all genetically differentiated and geographically isolated populations. ?? 2008 The Authors.

The Scala naturae revisited: evolutionary scales and anagenesis in comparative psychology.  

PubMed

Recent suggestions that evolutionary scales have a place in theorization about the evolution of behavior have been based on the concept of anagenesis, formerly associated with notions of biological progress. An associated concept is that of grades, often used as units of anagenetic advance. Advocates of anagenetic analysis in comparative psychology cite the writings of biologists Bernard Rensch, Julian Huxley, George Gaylord Simpson, and Stephen Jay Gould to support the usefulness of anagenesis but treat the positions of each of these theorists as if they were the same. In fact, they differ considerably in their definition of anagenesis and in its application to specific issues in evolution. The anagenetic approach is criticized as axiological and frequently anthropocentric. Although the formation of grades can be useful, a sequence of grades must not be assumed to represent historical stages in the evolution of specific structures or behaviors. PMID:1935002

Self-organized criticality and punctuated equilibria  

NASA Astrophysics Data System (ADS)

Many natural phenomena evolve intermittently, with periods of tranquillity interrupted by bursts of activity, rather than following a smooth gradual path. Examples include earthquakes, volcanic eruptions, solar flares, gamma-ray bursts, and biological evolution. Stephen Jay Gould and Niles Eldredge have coined the term ``punctuated equilibria'' for this behavior. We argue that punctuated equilibria reflects the tendency of dynamical systems to evolve towards a critical state, and review recent work on simple models. A good metaphoric picture is one where the systems are temporarily trapped in valleys of deformable, interacting landscapes. Similarities with spin glasses are pointed out. Punctuated equilibria are essential for the emergence of complex phenomena. The periods of stasis allow the system to remember its past history; yet the intermittent events permit further change.

[Interactions between genetics and environment].  

PubMed

From a scientific point of view, the idea that genes exert an important role in explaining human pathology has gained much popularity in recent decades. However, according to Stephen Jay Gould, the "genetic fallacy" has been repeatedly used to avoid environmental action. In the case of occupational cancer, genetic screening of workers for their susceptibility to the action of chemical carcinogens, on the basis of "metabolic polymorphisms", would be unacceptable because of racial discrimination, related to uneven racial distribution of most polymorphisms, for example, 90% of Africans and 10% of Asians have the "slow" acetylator genotype. Therefore, not only technical and scientific aspects of genetic susceptibility to cancer, but also ethical and social implication have to be considered. PMID:9673101

Geologic characterization of Caddo Limestone Reservoir, Curry Unit, Stephens County, north-central Texas  

SciTech Connect

Three classic carbonate models (carbonate bank, oolitic shoal, and tidal flat) are applied to interpret the depositional environments and diagenesis of the Caddo limestone (Middle Pennsylvanian). The study area is located in west-central Stephens County, approximately 4 mi southwest of Breckenridge, Texas. Phylloid algal mounds developed on a lower Caddo ramp, along the transition of the Concho platform and Fort Worth basin. Within the area defined as the Curry unit, phylloid algal mounds and intermound facies aggraded to sea level. This led to the development of an areally restricted carbonate bank. Some phylloid algal buildups underwent subaerial exposure, and fresh water leached unstable carbonate minerals, creating minor secondary porosity (<10%). An oolitic shoal (0-9.2 m thick) overlies and partially intergrades with the phylloid algal bank. Ooids were deposited along the margin of the preexisting bank, whereas fine-grained oolitic and peloidal packstone were deposited on the bank. The bank margin oolite exhibits oomoldic porosity in excess of 15%. The uppermost 6.1-24.4 m of the Caddo represents intertidal deposition. Sediment, primarily algal remains and carbonate mud, was deposited on a preexisting surface of ooids and peloids. Fenestral fabric. rhizoliths, brecciated zones, and small-scale channels are common features. A wide variety of pore types are present in the intertidal zone; intraskeletal, framework, biomoldic, and vuggy pores are most important. Throughout this zone, porosity exceeds 10% and permeability averages 12 md. The Curry unit has produced approximately 28 million bbl of oil (primary and secondary) from the upper Caddo. Depositional environments and diagenesis of the Caddo are complex. A greater understanding of these complexities may enable geoscientists to evaluate remaining future potential within the Caddo and in other similar carbonate accumulations.

Cultural Heritage Documentation by Combining Near-Range Photogrammetry and Terrestrial Laser Scanning: St. Stephen's Cathedral, Vienna  

NASA Astrophysics Data System (ADS)

A powerful sensor system providing both high-resolution textures and highly accurate 3D geometry information is created by combining near-range photogrammetry and terrestrial laser scanning. As both sensors are integrated closely into a single system, the textures can be applied to the 3D data automatically and with high precision. These sensors have proven as extremely valuable tools in applications of cultural heritage, architecture, and archaeology. We demonstrate the capabilities of the RIEGL LMS-Z420i system with an integrated high-resolution camera by presenting the work flow of data acquisition and postprocessing performed for modeling St. Stephen's Cathedral in Vienna, Austria, with an emphasis on the construction of CAD models.

From weird wonders to stem lineages: the second reclassification of the Burgess Shale fauna.  

PubMed

The Burgess Shale, a set of fossil beds containing the exquisitely preserved remains of marine invertebrate organisms from shortly after the Cambrian explosion, was discovered in 1909, and first brought to widespread popular attention by Stephen Jay Gould in his 1989 bestseller Wonderful life: The Burgess Shale and the nature of history. Gould contrasted the initial interpretation of these fossils, in which they were 'shoehorned' into modern groups, with the first major reexamination begun in the 1960s, when the creatures were perceived as 'weird wonders', possessing unique body plans and unrelated to modern organisms. More recently, a third phase of Burgess Shale studies has arisen, which has not yet been historically examined. This third phase represents a revolutionary new understanding, brought about, I believe, by a change in taxonomic methodology that led to a new perception of the Burgess creatures, and a new way to comprehend their relationships with modern organisms. The adoption of cladistics, and its corollary, the stem group concept, has forged a new understanding of the Burgess Shale ... but has it also changed the questions we are allowed to ask about evolution?

Why don't zebras have machine guns? Adaptation, selection, and constraints in evolutionary theory.  

PubMed

In an influential paper, Stephen Jay Gould and Richard Lewontin (1979) contrasted selection-driven adaptation with phylogenetic, architectural, and developmental constraints as distinct causes of phenotypic evolution. In subsequent publications Gould (e.g., 1997a,b, 2002) has elaborated this distinction into one between a narrow "Darwinian Fundamentalist" emphasis on "external functionalist" processes, and a more inclusive "pluralist" emphasis on "internal structuralist" principles. Although theoretical integration of functionalist and structuralist explanations is the ultimate aim, natural selection and internal constraints are treated as distinct causes of evolutionary change. This distinction is now routinely taken for granted in the literature in evolutionary biology. I argue that this distinction is problematic because the effects attributed to non-selective constraints are more parsimoniously explained as the ordinary effects of selection itself. Although it may still be a useful shorthand to speak of phylogenetic, architectural, and developmental constraints on phenotypic evolution, it is important to understand that such "constraints" do not constitute an alternative set of causes of evolutionary change. The result of this analysis is a clearer understanding of the relationship between adaptation, selection and constraints as explanatory concepts in evolutionary theory. PMID:18331960

PubMed

The aim of the present study was to assess the effect of six different temperatures on the development of Acarophenax lacunatus (Cross & Krantz) using eggs of Tribolium castaneum (Herbst) and Cryptolestes ferrugineus (Stephens) as hosts. The temperature affected the development of A. lacunatus. The largest values for the progeny (19 mites in T. castaneum and 15 mites in C. ferrugineus) were obtained at about 30 degrees C, as also observed for the net reproductive rate (Ro), which revealed that the A. lacunatus population increased 18 times in T. castaneum and 14 times in C. ferrugineus in a generation. The intrinsic rate of increase (r m) gradually increased with temperature, reaching the maximum value at 35 degrees C in T. castaneum (1,608) and C. ferrugineus (1,289). The generation time was negatively correlated with temperature, ranging from 1,60 to 4,85 days in T. castaneum and from 1,96 to 5,34 days in C. ferrugineus. These results suggest that the mite A. lacunatus may be used in programs of biological control of T. castaneum and C. ferrugineus in the tropics. PMID:17710330

High-current hunt for Bardeen-Stephen flux motion in A15 superconductor V3Si at high fields  

NASA Astrophysics Data System (ADS)

The motion of flux lines -- quantized supercurrent vortices -- is observed in a high-quality superconducting single crystal of V3Si with very little flux ``pinning''. Consequently flux lines are more free to move under a Lorentz force when a transport current is applied. This opens up the possibility of Bardeen-Stephen flux flow (BSFF), wherein flux lines move in an orderly fashion. BSFF is clearly recognizable by a linear dependence of its dissipation resistivity on applied field H and can be observed in voltage vs. current (VI) curves. Since this requires both pinning-free samples and currents in the tens to hundreds of amperes, BSFF is difficult to attain especially because of current-induced heating. In this study, heating is significantly reduced via ultrasonically soldered contacts, pulsed currents, and submerging the sample in liquid helium. Measuring from fields of 6 T up to 20 T, dissipation levels characteristic of ordered flux flow are clearly distinguishable, along with other interesting features such as the ``peak'' effect in critical current Jc(H) seen only when pinning energy density is comparable to the elasticity of the flux medium. The data and their interesting ramifications will be discussed.

Cytotoxic effects of Jay Amin hydroxamic acid (JAHA), a ferrocene-based class I histone deacetylase inhibitor, on triple-negative MDA-MB231 breast cancer cells.  

PubMed

The histone deacetylase inhibitors (HDACis) are a class of chemically heterogeneous anticancer agents of which suberoylanilide hydroxamic acid (SAHA) is a prototypical member. SAHA derivatives may be obtained by three-dimensional manipulation of SAHA aryl cap, such as the incorporation of a ferrocene unit like that present in Jay Amin hydroxamic acid (JAHA) and homo-JAHA [ Spencer , et al. ( 2011 ) ACS Med. Chem. Lett. 2 , 358 - 362 ]. These metal-based SAHA analogues have been tested for their cytotoxic activity toward triple-negative MDA-MB231 breast cancer cells. The results obtained indicate that of the two compounds tested, only JAHA was prominently active on breast cancer cells with an IC(50) of 8.45 ?M at 72 h of treatment. Biological assays showed that exposure of MDA-MB231 cells to the HDACi resulted in cell cycle perturbation with an alteration of S phase entry and a delay at G(2)/M transition and in an early reactive oxygen species production followed by mitochondrial membrane potential (MMP) dissipation and autophagy inhibition. No annexin binding was observed after short- (5 h) and longer (24 and 48 h) term incubation with JAHA, thereby excluding the promotion of apoptosis by the HDACi. Although caution must be exercised in extrapolation of in vitro results to the in vivo situation for which research on animals and human trials are needed, nevertheless JAHA treatment possesses the potential for its development as an agent for prevention and/or therapy of "aggressive" breast carcinoma, thus prompting us to get more insight into the molecular basis of its antibreast cancer activity.

Ecology and dynamics of the blood parasite, Hepatozoon tuatarae (Apicomplexa), in tuatara (Sphenodon punctatus) on Stephens Island, New Zealand.  

PubMed

We explored infection patterns and temporal dynamics of the protozoan blood parasite Hepatozoon tuatarae (Apicomplexa) infecting the tuatara (Sphenodon punctatus), a protected reptile living on Stephens Island, New Zealand. In March 2006, we surveyed tuatara in five study sites to examine spatial variation in infection prevalence, and four times, from May 2005 to November 2006, we recaptured marked individuals within three study sites to examine the temporal dynamics of infection. We also examined how blood-parasite infection patterns were influenced by host sex, body size, and host infestation with ticks (Amblyomma sphenodonti) and mites (Neotrombicula spp.), which are potential vectors of the blood parasite. Infection prevalence (16.9-24% infected) and intensity (<0.01-0.1% blood cells infected) were low in all samples. Infection intensity varied among the five sampled sites in March 2006, but prevalence did not. Neither infection prevalence nor intensity varied with time, and infections were detected in consecutive samples from recaptured individuals for up to 18 mo. Neither survey showed an influence of host sex on infection, but both surveys showed infection intensity declined with increasing host body size, as did infection prevalence in the spatial survey. In the temporal survey, we found a positive relationship between the tick numbers on hosts and blood-parasite infection intensity, which were stronger in two of the sampling periods and among larger hosts. These data suggest that exposure and susceptibility to infection decreases with host size and that ticks, but not mites, are probably the vectors in this ancient host-parasite association of a long-lived (>50 yr) host.

Effects of mating status, sex ratio, and population density on longevity and offspring production of Cryptolestes ferrugineus (Stephens) (Coleoptera: Cucujidae).  

PubMed

The life span and reproductive rate of the rusty grain beetle, Cryptolestes ferrugineus (Stephens), were determined at different adult densities and sex ratios at 30 +/- 1 degree C, 75 +/- 5% relative humidity (RH), and with feed consisting of ground wheat plus wheat germ (4:1, w/w). The mean life spans of adult beetles were 32 weeks for adults individually isolated in separate vials, 22 to 25 weeks for adults of different strains kept one male and one female per vial, 24 weeks for a group of 30 virgin females together in one vial, 13 weeks for a group of 30 virgin males together in one vial, 14 weeks for groups with 10 males and 20 females per vial, 13 weeks for groups with 15 males and 15 females per vial, and 12 weeks for groups with 20 males and 10 females per vial. When kept one adult per vial, males and females had similar life spans; when kept one male and one female per vial, males lived longer; when kept in groups of 30 per vial females lived longer, except in the group which had a sex ratio of two males to one female; in this group life spans of males and females were the same. Females in separate vials with one male produced mean numbers of of offspring ranging from 389 for an inbred homozygous malathion-resistant strain to 514 for an outbred strain (genetically variable: GV). GV strain females in vials which had 10 males and 20 females produced a mean of 97 offspring, GV strain females in vials which had 15 males and 15 females produced a mean of 146 offspring, and GV strain females in vials which had 20 males and 10 females produced a mean of 216 offspring. The results of this study and similar studies on other insect species suggest that the life span of this insect is inversely related to the rate at which it expends energy and to injury incurred during copulation, and that oviposition rate decreases as the density of larvae and female adults increases.

Local knowledge, environmental politics, and the founding of ecology in the United States. Stephen Forbes and "The Lake as a Microcosm" (1887).  

PubMed

Stephen Forbes's "The Lake as a Microcosm" is one of the founding documents of the science of ecology in the United States. By tracing the connections between scientists and local fishermen underlying the research on floodplain lakes presented in "The Lake as a Microcosm," this essay shows how the birth of ecology was tied to local knowledge and the local politics of environmental transformation. Forbes and the other scientists of the Illinois Natural History Survey relied on fishermen for manual labor, expertise in catching fish, and knowledge of the natural history of the fishes. As Forbes and his colleagues worked in close contact with fishermen, they also adopted many of their political concerns over the privatization of the floodplain and became politically active in supporting their interests. The close connection between scientists and local knowledge forced the ecologists to reframe the boundaries of ecology as objective or political, pure or applied, local or scientific. PMID:11284229

Topical toxicity of two acetonic fractions of Trichilia havanensis Jacq. and four insecticides to larvae and adults of Chrysoperla carnea (Stephens) (Neuroptera: Chrysopidae).  

PubMed

The toxicity of botanical origin compounds such as two acetonic fractions of the seed kernels of the Meliacea Trichilia havanensis Jacq with insecticide properties (azadirone (F12) and the mixture F18 [1,7+3,7-di-O-acethylhavanensin (4:1)], three insecticides commercially available (imidacloprid, natural pyrethrins+PBO, triflumuron) and phloxine B, were tested in the laboratory. Topical bioassays using third instar and newly emerged adults of the lacewing Chrysoperla carnea (Stephens) at the maximum field recommended rate in Spain for commercials and at 1,000 ppm of active ingredient for T. havanensis acetone fractions and phloxine-B, were carried out. Imidacloprid and triflumuron were very toxic to third instar larvae inhibiting adult emergence, being the rest of insecticides harmless. Fecundity and fertility were not affected by the non-toxic compounds. Concerning adults, only imidacloprid and natural pyrethrins killed them significantly 24 hours after treatment. Phloxine B, triflumuron and T. havanensis fractions were harmless and did not cause any effect on fecundity and fertility with the exception of triflumuron, which reduced considerably the egg hatch. It can be concluded that T. havanensis acetonic fractions and phloxine B were non-toxic to larvae and adults of C. carnea when treated topically, whereas triflumuron, natural pyrethrins and imidacloprid affected one or more of the evaluated parameters under our conditions.

My Most Memorable AAS Meeting, or How Stephen Hawking's Chauffeur and Chubby Wise's Fiddle Are Related to the Hubble Deep Field (At Least In My Mind and Experience!)  

NASA Astrophysics Data System (ADS)

Sometimes, in the most extraordinary conditions and times, strange things happen which remind us of just how small a world we really inhabit, and how so many varied things may suddenly be juxtaposed in our lives, and in the lives of others. My most memorable AAS meeting involves not only the meeting but events while getting there. It was January 1996, and we had just finished our observations and initial data reduction of the Hubble Deep Field, the members of the HDF working group doggedly coming in to the STScI by various means over the December holidays and the New Year, in the midst of several blizzards which even closed STScI for a number of days. Not surprisingly, work on the HDF AAS presentations was ongoing until the last minute, until people left snowy Baltimore for sunny San Antonio. My street was plowed for the first time in a week a few hours before my 6AM flight, so after digging out my car, with no time for sleep, between 3AM and 6AM on the morning I left, I soon discovered my own surprising connections between Stephen Hawking's chauffeur, Chubby Wise's fiddle, and the Hubble Deep Field. I'll elaborate in this paper if you're curious!

Synthetic biology: a challenge to mechanical explanations in biology?  

PubMed

In their plans to modify organisms, synthetic biologists have contrasted engineering and tinkering. By drawing this contrast between their endeavors and what has happened during the evolution of organisms by natural selection, they underline the novelty of their projects and justify their ambitions. Synthetic biologists are at odds with a long tradition that has considered organisms as "perfect machines." This tradition had already been questioned by Stephen Jay Gould in the 1970s and received a major blow with the comparison made by François Jacob between organisms and the results of "bricolage" (tinkering). These contrasts between engineering and tinkering, synthetic biology and evolution, have no raison d'être. Machines built by humans are increasingly inspired by observations made on organisms. This is not a simple reversal of the previous trend-the mechanical conception of organisms-in which the characteristics of the latter were explained by comparison with human-built machines. Relations between organisms and machines have always been complex and ambiguous. PMID:23502563

French tradition and the rise of Evo-devo.  

PubMed

The limited value most French biologists attributed to Darwinism and Mendelism in the first half of the twentieth century, and their conviction that these theories were at best insufficient to explain evolution and development, probably created conditions propitious to the development of Evo-devo at the end of the century. The separation between embryology and evolution did not exist in French biology as it did in American genetics: explanations for these two phenomena were sought equally in the "organization" of the egg. The major contribution of French biologists to Evo-devo was clearly the invention of the notion of the regulatory gene by Jacob and Monod; not the operon model per se, but the introduction of a hierarchy between two different kinds of genes. The consequence, the rise of the developmental gene concept, was not immediate, and required the active role of other biologists such as Antonio Garcia-Bellido, Allan Wilson and Stephen Jay Gould. Various obstacles had to be overcome for this concept of developmental gene to be fully accepted. PMID:17990019

Toward a general theory of adaptive radiation: insights from microbial experimental evolution.  

PubMed

The history of life has been punctuated by unusually spectacular periods of evolutionary diversification called adaptive radiation. Darwin's finches in the Galapagos, cichlid fishes in African Rift and Nicaraguan crater lakes, and the emergence of mammals at the end of the Cretaceous are hallmark examples. Although we have learned much from these and other case studies about the mechanisms thought to drive adaptive radiations, convincing experimental tests of theory are often lacking for the simple reason that it is usually impossible to "rewind the tape of life," as Stephen Jay Gould was fond of saying, and run it again. This situation has changed dramatically in recent years with the increasing emphasis on the use of microbial populations which, because of their small size and rapid generation times, make possible the construction of replicated, manipulative experiments to study evolution in the laboratory. Here I review the contributions that microbial experimental evolution has made to our understanding of the ecological and genetic mechanisms underlying adaptive radiation. I focus on three major gaps in the theory of adaptive radiation--the paucity of direct tests of mechanism, the genetics of diversification, and the limits and constraints on the progress of radiations--with the aim of pointing the way toward the development of a more general theory of adaptive radiation.

Antievolutionism in the Antipodes: from protesting evolution to promoting creationism in New Zealand.  

PubMed

Like other English-speaking peoples around the world, New Zealanders began debating Darwinism in the early 1860s, shortly after the publication of Charles Darwin's Origin of Species. Despite the opposition of some religious and political leaders - and even the odd scientist - biological evolution made deep inroads in a culture that increasingly identified itself as secular. The introduction of pro-evolution curricula and radio broadcasts provoked occasional antievolution outbursts, but creationism remained more an object of ridicule than a threat until the last decades of the twentieth century, when first American and then Australian creationists began fomenting antievolutionism among New Zealanders. Although Stephen Jay Gould assured them in 1986 that they had little to fear from so-called scientific creationism, because it was a 'peculiarly American' phenomenon, scientific creationism by the mid-1990s had captured the allegiance of an estimated five per cent of the country and proved especially attractive to Maori and Pacific Islanders. In 1992 New Zealand creationists formed their own antievolution society, Creation Science (NZ). PMID:11624666

Use of organic petrology in sequence stratigraphic interpretations: Example from the Eocene-Oligocene boundary section, St. Stephens Quarry, Washington County, Alabama  

SciTech Connect

The type and preservation of organic matter is related to the depositional systems tract in which the sediments were deposited. Shelf sediments in the transgressive systems tract contain sparse, highly degraded phytoclasts whereas organic matter in the highstand systems tract is dominated by well-preserved phytoclasts introduced to the shelf during progradation. Because of this relationship, integration of data from organic petrology with sedimentologic and biostratigraphic results provides greater resolution in locating critical surfaces (sequence boundaries, transgressive surfaces, and surfaces of maximum starvation) that bound depositional systems tracts within the depositional sequence. The Eocene Oligocene shelf sediments exposed in St. Stephens Quarry provide an excellent example of the relationship between depositional systems tract and organic matter deposition. Deposition of the Shubuta Clay in the transgressive systems tract terminated with the surface of maximum starvation. This surface is marked by a thin (<2 cm), laterally extensive, phosphate-rich shell lag that contains only minor amounts of highly degraded phytoclasts. Graphic correlation of biostratigraphic data reveals a marine hiatus (120,000 years) within the shell lag. Deposition in the subsequent highstand systems tract resulted in an increase in well-preserved phytoclasts in the overlying Bumpnose Limestone and Red Bluff Clay. A transgressive surface forms the contact between the Red Bluff Clay and the Mint Springs Marl. Phytoclasts are less common and more degraded in the Mint Springs above the transgressive surface than in the Red Bluff below. No hiatus is observed at this surface, suggesting that the type 2 sequence boundary is conformable at this section and may exist in the Red Bluff below the transgressive surface. This integrated approach confirms and refines previous sequence stratigraphic work performed on this important Gulf Coast section.

Jay Carter Enterprises, Incorporated steam engine  

NASA Astrophysics Data System (ADS)

The Small Community Solar Thermal Power Experiment (SCSE) selected an organic rankine cycle (ORC) engine driving a high speed permanent magnet alternator (PMA) as the baseline power conversion subsystem (PCS) design. The back-up conceptual PCS design is a steam engine driving an induction alternator delivering power directly to the grid. The development of the automotive reciprocating simple rankine cycle steam engine and how an engine of similar design might be incorporated into the SCSE is discussed. A description of the third generation automotive engine is included along with some preliminary test data. Tests were conducted with the third generation engine driving an induction alternator delivering power directly to the grid. The purpose of these tests is to further verify the effects of expander inlet temperature, input thermal power level, expansion ratio, and other parameters affecting engine performance to aid in the development of an SCSE PCS.

'Primum non nocere': A review of Taking America off Drugs: Why Behavioral Therapy is More Effective for Treating ADHD, OCD, Depression and Other Psychological Problems by Stephen Ray Flora  

PubMed Central

Taking America off Drugs by Stephen Ray Flora provides an overview of effective behavioral interventions to treat a variety of mental health concerns, including depression and phobias. These disorders are better treated with behavioral than psychopharmacological interventions. Yet, the latter prevail in today's society. Taking America off Drugs provides the background to help us understand why, as it puts the treatment of behavioral disorders in the context of modern psychiatry and its relationship with the pharmaceutical industry. This review provides an overview and critical evaluation of the book, but it also extends its context by discussing the history of the treatment of mental illness and practices of the pharmaceutical-medical complex and by offering an optimistic scenario by which psychopharmacological agents will ultimately be replaced by interventions based on the principles of applied behavior analysis.

Spanish Flu and Early 20th-Century Expansion of a Coronary Heart Disease-Prone Subpopulation  

PubMed Central

According to Stephen Jay Gould, “we have a strong preference for seeing trends as entities moving somewhere.” However, trends may instead be the product of relative expansions and contractions of different subpopulations constituting the system. Variation in attributes of coronary heart disease cases during the decline in coronary heart disease mortality suggests a change in the primary source-subpopulation of cases over time. It is proposed that an early 20th-century expansion of a coronary heart disease–prone subpopulation, characterized by high serum-cholesterol phenotype and high case-fatality—which contributed to most of the coronary heart disease cases and deaths during the 1960s—may have been a late result of the 1918 influenza pandemic. The same unusual immune response to infection that in 1918 killed preferentially men, whites, and those born from 1880 to 1900 (20–40 years old) may have “primed” survivors of those birth cohorts to late coronary heart disease mortality. Ecologic evidence in favor of a birth cohort and geographic association between both epidemics is presented. Cross-reactive auto-immune response upon reinfection could explain the excess coronary heart disease deaths reported during influenza epidemics from the late 1920s onward. Mimicry between the viral hemagglutinin and the apolipoprotein B or the low-density lipoprotein receptor could be the link between infection and hypercholesterolemia. The extinction of those birth cohorts would result in a relative increase in cases coming from a 2nd subpopulation, which was characterized by insulin resistance and chronic expression of low-grade inflammation markers and was comparatively less vulnerable to die acutely from coronary heart disease.

Goethe's phenomenology of nature: a juvenilization of science.  

PubMed

Empirical science is not a mere collection of facts. It builds theories and frames hypotheses within those theories. Empirical theories are stated as plausible answers to questions we pose to nature. According to the Galilean-Baconian tradition within science, these questions should basically explore the causes of observed phenomena, and further be restricted to the measurable and quantitative realm. Thus, the answers are generally expected to explain the effective causes behind the actual phenomena. By framing falsifiable hypotheses, the theories are tested against the empirical foundation on which they rest. In this way we try to relieve science from false theories. Thus, we have two epistemological levels: First, the theoretical level; the scientific theory explaining the phenomena, and second, the empirical level; the phenomena or facts verifying or falsifying those theories. According to the poet and multi-scientist Johann Wolfgang von Goethe (1749-1832), there is however another way of science, namely an approach where these two levels fuse and become one. Goethe intended this approach to be a complementation of the Galilean-Baconian method, more than an alternative. He considered his "hypothesis-free method" to be a more comprehensive and secure way to understand nature. Whereas the Galilean-Baconian method aimed at explaining the effective causes of natural phenomena, in order to control and exploit nature for technical and industrial purposes, Goethe aimed at an exposition of the inherent meaning of the phenomena.We will explore, exemplify and discuss this approach with reference to the inherently Goethean phenomenology of evolution credited to the Dutch anatomist Louis Bolk (1866-1930), later commented and complemented by Stephen Jay Gould (1941-2002) and Jos Verhulst (1949 ). In the course of this presentation we will outline the Goethean approach as a method representing a juvenilization or in Bolk's terms, a fetalization of science. PMID:20077388

USGS Publications Warehouse

While encamped for the winter of 1819?1820 at Engineer Cantonment along the Missouri River in present-day eastern Nebraska, members of Major Stephen Harriman Long?s Expedition to the Rocky Mountains collected a number of animals that were previously unknown. Among the mammals were two soricids that were subsequently described by Thomas Say as Sorex brevicaudus (Northern Short-tailed Shrew, Blarina brevicauda) and Sorex parvus (Least Shrew, Cryptotis parvus). The holotypes of these species were deposited and placed on public exhibit in the Philadelphia Museum, the predominant North American systematic collection of the early nineteenth century. Like most private museums of that era, the Philadelphia Museum eventually went out of business, and its collections were dispersed and, for the most part, lost. Fortunately, Titian R. Peale made a detailed field sketch of the two specimens soon after their capture and subsequently executed a watercolor based on that sketch. In addition, an engraving of the holotypes was published in the decade following the discovery of the two species. Illustrations of holotypes are taxonomically useful when they depict diagnostic characters of species. They take on added taxonomic significance in the absence of the holotypes. In the cases of Sorex brevicaudus and Sorex parvus, pictures provide strong confirmation of the taxonomic identities of these two species, as well as recording the early history of the specimens.

Stephen C. Woods: a precocious scientist.  

PubMed

To investigate the early scientific development of Steve Woods, I reviewed his research during the first decade after he received his doctoral degree in 1970. The main parts of his research program were conditioned insulin secretion and hypoglycemia, Pavlovian conditioning of insulin secretion before a scheduled access to food, and basal insulin as a negative-feedback signal from fat mass to the brain. These topics were pursued with experimental ingenuity; the resulting publications were interesting, clear, and rhetorically effective. Although the theoretical framework for his experiments with insulin was homeostatic, by the end of the decade he suggested that classic negative-feedback homeostasis needed to be revised to include learning acquired by lifestyle. Thus, Woods functioned as a mature scientist from the beginning of his research-he was very precocious. This precocity also characterized his teaching and mentoring as recalled by two of his students during that time, Joseph Vasselli and Paul Kulkosky. The most unusual and exemplary aspect of his precocity is that the outstanding performance of his first decade was maintained during the subsequent 30years. PMID:21232549

Einstein had curved space, Hawking will curve time. Hawking's universe is a closed model, a 4-sphere, which encloses its own space and its own time. Nothing exists outside and without any time overlapping this 4-sphere, it cannot have a beginning, an evolution or an end. It only is. But such an absolute existence of this type of universe implies that its 3-dimensional sclices - which are our physical space - cannot have the same absolute state of being. Thus, they are necessarily transitory, with a beginning and an end, in time which is the 4th remaining dimension of the 4-sphere. Hawking absolute universe is the cause of time.

Larval biology of the crab Rhithropanopeus harrisii (Gould): a synthesis.  

PubMed

This synthesis reviews the physiological ecology and behavior of larvae of the benthic crab Rhithropanopeus harrisii, which occurs in low-salinity areas of estuaries. Larvae are released rhythmically around the time of high tide in tidal estuaries and in the 2-h interval after sunset in nontidal estuaries. As in most subtidal crustaceans, the timing of larval release is controlled by the developing embryos, which release peptide pheromones that stimulate larval release behavior by the female to synchronize the time of egg hatching. Larvae pass through four zoeal stages and a postlarval or megalopal stage that are planktonic before metamorphosis. They are retained near the adult population by means of an endogenous tidal rhythm in vertical migration. Larvae have several safeguards against predation: they undergo nocturnal diel vertical migration (DVM) and have a shadow response to avoid encountering predators, and they bear long spines as a deterrent. Photoresponses during DVM and the shadow response are enhanced by exposure to chemical cues from the mucus of predator fishes and ctenophores. The primary visual pigment has a spectral sensitivity maximum at about 500 nm, which is typical for zooplankton and matches the ambient spectrum at twilight. Larvae can detect vertical gradients in temperature, salinity, and hydrostatic pressure, which are used for depth regulation and avoidance of adverse environmental conditions. Characteristics that are related to the larval habitat and are common to other crab larval species are considered. PMID:19556592

Electroantennogram responses of Chrysoperla carnea (Stephens) to volatiles.  

PubMed

Electrophysiological responses of adult males and females of C. carnea to commonly occurring plant volatiles were recorded using the electroantennogram technique. Responses to 28 volatiles evaluated indicate that both depolarization and recovery to the baseline were rapid in females compared to males. Normalized EAG responses relative to the standard, trans-caryophyllene reveal significant differences between the chemicals as also between the sexes. The response of males to several of the compounds, particularly the terpenoids was higher than females. The pooled averages to the different classes of chemical compounds reveal greater response for fatty acid derivatives and terpenoids, particularly the oxygenated monoterpenes and the sesquiterpenes. These findings are discussed in relation to volatiles released in the cotton ecosystem. PMID:15623237

St. Stephen powerhouse tailrace velocity measurement. Final report  

SciTech Connect

Tests were conducted to provide a prototype evaluation of the operating conditions of the project and to evaluate the adequacy of the repairs and remedial work performed in the channel downstream of the tailrace. Prototype measurements were made to define the relative magnitudes of velocities and the surface flow patterns in the channel downstream of the tailrace and the displacement, if any, of the stone protection material resulting from various turbine operations and tailwater conditions. Results of the data collection included determination of (a) velocity distribution at various ranges across the channel; (b) velocity profiles at the toe of the slope and at the observed location of highest velocity; and (c) unusual surface flow patterns that are produced by different combinations of turbine operations. Recommendations for start-up and shut-down procedures for the turbine operations that would produce the most acceptable. The depth soundings revealed that the stone protection material was quite stable (District surveys reveal that no appreciable displacement has occurred during the subsequent months of operation of the powerhouse.) The flow velocities were found to concentrate along the right side of the channel as a result of uneven flow distribution from the draft tube bays and the asymmetrical geometry along the left side of the tailrace. Return flows were observed and found to concentrate along the left side of the channel except when all three turbines were operating. Operating recommendations for the turbines are made based on tailwater conditions, length of time of nonoperation of the powerhouse, and the velocity data obtained from the tests.

The Gould's Belt Very Large Array Survey. I. The Ophiuchus Complex  

NASA Astrophysics Data System (ADS)

We present large-scale (~2000 arcmin2), deep (~20 ?Jy), high-resolution (~1'') radio observations of the Ophiuchus star-forming complex obtained with the Karl G. Jansky Very Large Array at ? = 4 and 6 cm. In total, 189 sources were detected, 56 of them associated with known young stellar sources, and 4 with known extragalactic objects; the other 129 remain unclassified, but most of them are most probably background quasars. The vast majority of the young stars detected at radio wavelengths have spectral types K or M, although we also detect four objects of A/F/B types and two brown dwarf candidates. At least half of these young stars are non-thermal (gyrosynchrotron) sources, with active coronas characterized by high levels of variability, negative spectral indices, and (in some cases) significant circular polarization. As expected, there is a clear tendency for the fraction of non-thermal sources to increase from the younger (Class 0/I or flat spectrum) to the more evolved (Class III or weak line T Tauri) stars. The young stars detected both in X-rays and at radio wavelengths broadly follow a Güdel-Benz relation, but with a different normalization than the most radioactive types of stars. Finally, we detect a ~70 mJy compact extragalactic source near the center of the Ophiuchus core, which should be used as gain calibrator for any future radio observations of this region.

1. The effects of a sudden decrease in salinity and exposure to sublethal concentrations of the herbicide, alachlor, on osmoregulation and respiration of the crab, Rithropanopeus harrisii, were studied. 2. Crabs were hyperosmotic regulators at salinities below 24 ppt and became hypoosmotic at higher salinities. Upon a salinity decrease from 20 to 1 ppt, crabs adjusted their haemolymph osmolality to a stable hyperosmotic level in 8 hr. Alachlor concentrations to 50 ppm did not affect this adjustment. 3. A salinity decrease from 10 to 0 ppt elevated VO2 and the critical oxygen tension. This response was unaffected by alachlor concentrations as high as 25 ppm. PMID:2573450

The insulin-like growth factor-binding protein (IGFBP) superfamily.  

PubMed

Over the last decade, the concept of an IGFBP family has been well accepted, based on structural similarities and on functional abilities to bind IGFs with high affinities. The existence of other potential IGFBPs was left open. The discovery of proteins with N-terminal domains bearing striking structural similarities to the N terminus of the IGFBPs, and with reduced, but demonstrable, affinity for IGFs, raised the question of whether these proteins were "new" IGFBPs (22, 23, 217). The N-terminal domain had been uniquely associated with the IGFBPs and has long been considered to be critical for IGF binding. No other function has been confirmed for this domain to date. Thus, the presence of this important IGFBP domain in the N terminus of other proteins must be considered significant. Although these other proteins appear capable of binding IGF, their relatively low affinity and the fact that their major biological actions are likely to not directly involve the IGF peptides suggest that they probably should not be classified within the IGFBP family as provisionally proposed (22, 23). The conservation of this single domain, so critical to high-affinity binding of IGF by the six IGFBPs, in all of the IGFBP-rPs, as well, speaks to its biological importance. Historically, and perhaps, functionally, this has led to the designation of an "IGFBP superfamily". The classification and nomenclature for the IGFBP superfamily, are, of course, arbitrary; what is ultimately relevant is the underlying biology, much of which still remains to be deciphered. The nomenclature for the IGFBP related proteins was derived from a consensus of researchers working in the IGFBP field (52). Obviously, a more general consensus on nomenclature, involving all groups working on each IGFBP-rP, has yet to be reached. Further understanding of the biological functions of each protein should help resolve the nomenclature dilemma. For the present, redesignating these proteins IGFBP-rPs simplifies the multiple names already associated with each IGFBP related protein, and reinforces the concept of a relationship with the IGFBPs. Beyond the N-terminal domain, there is a lack of structural similarity between the IGFBP-rPs and IGFBPs. The C-terminal domains do share similarities to other internal domains found in numerous other proteins. For example, the similarity of the IGFBP C terminus to the thyroglobulin type-I domain shows that the IGFBPs are also structurally related to numerous other proteins carrying the same domain (87). Interestingly, the functions of the different C-terminal domains in members of the IGFBP superfamily include interactions with the cell surface or ECM, suggesting that, even if they share little sequence similarities, the C-terminal domains may be functionally related. The evolutionary conservation of the N-terminal domain and functional studies support the notion that IGFBPs and IGFBP-rPs together form an IGFBP superfamily. A superfamily delineates between closely related (classified as a family) and distantly related proteins. The IGFBP superfamily is therefore composed of distantly related families. The modular nature of the constituents of the IGFBP superfamily, particularly their preservation of an highly conserved N-terminal domain, seems best explained by the process of exon shuffling of an ancestral gene encoding this domain. Over the course of evolution, some members evolved into high-affinity IGF binders and others into low-affinity IGF binders, thereby conferring on the IGFBP superfamily the ability to influence cell growth by both IGF-dependent and IGF-independent means (Fig. 10). A final word, from Stephen Jay Gould (218): "But classifications are not passive ordering devices in a world objectively divided into obvious categories. Taxonomies are human decisions imposed upon nature--theories about the causes of nature's order. The chronicle of historical changes in classification provides our finest insight into conceptual revolutions PMID:10605625

At Home in the Universe - The Search for the Laws of Self-Organization and Complexity  

NASA Astrophysics Data System (ADS)

A major scientific revolution has begun, a new paradigm that rivals Darwin's theory in importance. At its heart is the discovery of the order that lies deep within the most complex of systems, from the origin of life, to the workings of giant corporations, to the rise and fall of great civilizations. And more than anyone else, this revolution is the work of one man, Stuart Kauffman, a MacArthur Fellow and visionary pioneer of the new science of complexity. Now, in At Home in the Universe , Kauffman brilliantly weaves together the excitement of intellectual discovery and a fertile mix of insights to give the general reader a fascinating look at this new science--and at the forces for order that lie at the edge of chaos.We all know of instances of spontaneous order in nature--an oil droplet in water forms a sphere, snowflakes have a six-fold symmetry. What we are only now discovering, Kauffman says, is that the range of spontaneous order is enormously greater than we had supposed. Indeed, self-organization is a great undiscovered principle of nature. But how does this spontaneous order arise? Kauffman contends that complexity itself triggers self-organization, or what he calls "order for free," that if enough different molecules pass a certain threshold of complexity, they begin to self-organize into a new entity--a living cell. Kauffman uses the analogy of a thousand buttons on a rug--join two buttons randomly with thread, then another two, and so on. At first, you have isolated pairs; later, small clusters; but suddenly at around the 500th repetition, a remarkable transformation occurs--much like the phase transition when water abruptly turns to ice--and the buttons link up in one giant network. Likewise, life may have originated when the mix of different molecules in the primordial soup passed a certain level of complexity and self-organized into living entities (if so, then life is not a highly improbable chance event, but almost inevitable). Kauffman uses the basic insight of "order for free" to illuminate a staggering range of phenomena. We see how a single-celled embryo can grow to a highly complex organism with over two hundred different cell types. We learn how the science of complexity extends Darwin's theory of evolution by natural selection: that self-organization, selection, and chance are the engines of the biosphere. And we gain insights into biotechnology, the stunning magic of the new frontier of genetic engineering--generating trillions of novel molecules to find new drugs, vaccines, enzymes, biosensors, and more. Indeed, Kauffman shows that ecosystems, economic systems, and even cultural systems may all evolve according to similar general laws, that tissues and terra cotta evolve in similar ways. And finally, there is a profoundly spiritual element to Kauffman's thought. If, as he argues, life were bound to arise, not as an incalculably improbable accident, but as an expected fulfillment of the natural order, then we truly are at home in the universe. Kauffman's earlier volume, The Origins of Order , written for specialists, received lavish praise. Stephen Jay Gould called it "a landmark and a classic." And Nobel Laureate Philip Anderson wrote that "there are few people in this world who ever ask the right questions of science, and they are the ones who affect its future most profoundly. Stuart Kauffman is one of these." In At Home in the Universe , this visionary thinker takes you along as he explores new insights into the nature of life.

What is Radical Behaviorism? A Review of Jay Moore's Conceptual Foundations of Radical Behaviorism  

PubMed Central

B. F. Skinner founded both radical behaviorism and behavior analysis. His founding innovations included: a versatile preparation for studying behavior; explicating the generic nature of stimulus and response; a pragmatic criterion for defining behavioral units; response rate as a datum; the concept of stimulus control; the concept of verbal behavior; and explicating the explanatory power of contingencies. Besides these achievements, however, Skinner also made some mistakes. Subsequent developments in radical behaviorist thought have attempted to remedy these mistakes. Moore's book presents a “party line” version of radical behaviorism. It focuses narrowly on a few of Skinner's concepts (mostly mentalism and verbal behavior) and contains no criticism of his mistakes. In fact, Moore adds a few mistakes of his own manufacture; for example, he insists that the mental realm does not exist—an unprovable and distracting assertion. The book's portrayal of behavior analysis would have been current around 1960; it mentions almost none of the developments since then. It also includes almost no developments in radical behaviorism since Skinner. Moore's book would give an unwary reader a highly distorted picture of contemporary behavior analysis and radical behaviorism.

Dementia and Alzheimer's disease: A new direction. The 2010 Jay L. Foster Memorial Lecture  

PubMed Central

Background The modern era of Alzheimer’s disease (AD) research began in the early 1980s with the establishment of AD research centers and expanded research programs at the National Institute on Aging. Methods Over the past 30 years, there has been success in defining criteria for AD and dementia, association of important genetic disorders related to premature dementia in families, the association of apolipoprotein-E4, and measurement of incidence and prevalence and selected risk factors. However, prevention and treatment have been elusive. Results The development of new technologies, especially magnetic resonance imaging, positron emission tomography to measure amyloid in vivo in the brain and glucose metabolism, cerebrospinal fluid examination, better genetic markers, large-scale longitudinal epidemiology studies, and preventive clinical trials has rapidly begun a new era of research that offers opportunities to better understand etiology, that is, determinants of amyloid biology in the brain, neurofibrillary tangles, synaptic loss, and dementia. Conclusions There are three major hypotheses related to dementia: amyloid deposition and secondary synaptic loss as a unique disease, vascular injury, and “aging.” New research must be hypothesis-driven and lead to testable approaches for treatment and prevention.

Ultrastructure of the abdominal sense organ of the scallop Mizuchopecten yessoensis (Jay).  

PubMed

The sensory epithelium of the abdominal sense organ (ASO) of the scallop Mizuchopecten yessoensis is composed of three cell types, sensory cells, mucous cells, and multiciliated cells. Sensory cells bear a single long (up to 250 microm) cilium surrounded by an inner ring of nine modified microvilli and an outer ring of ordinary microvilli paired with modified microvilli. Sensory cells make up about 90% of the total number of cells in the sensory epithelium. Mucous cells, which are much wider than sensory cells, bear only ordinary microvilli on their apical surface. Rare multiciliated cells with short (4-6 microm) cilia are scattered in the periphery of the sensory epithelium sheet. All hairs, cilium, and microvilli of each sensory cell are interconnected by a fibrous network. Nine modified microvilli of a single cell are interconnected by prominent laterally running fibrous links. Membrane-associated electron-dense material of modified microvilli is connected to the ciliary membrane-associated electron-dense material by fine string-like links. These links mechanically bridge the space between the cilium and modified microvilli, as do mechanical links, described for the stereocilia and kinocilium of vertebrate vestibular and cochlear hair cells. The proximal portion of a sensory cilium is about 100 microm long and has a typical 9 x 2+2 axoneme arrangement. The distal portion of a cilium is approximately 2 times thinner than the proximal one and is filled with homogeneous electron-dense material. Along the distal portion, diffuse material associated with the external surface of the membrane is found. The rigidity of distal portion of a cilium is much less than that of the proximal one.

We present Spitzer Space Telescope IRAC and MIPS observations of a 0.85 deg{sup 2} field including the Corona Australis (CrA) star-forming region. At a distance of 130 pc, CrA is one of the closest regions known to be actively forming stars, particularly within its embedded association, the Coronet. Using the Spitzer data, we identify 51 young stellar objects (YSOs) in CrA which include sources in the well-studied Coronet cluster as well as sources distributed throughout the molecular cloud. Twelve of the YSOs discussed are new candidates, one of which is located in the Coronet. Known YSOs retrieved from the literature are also added to the list, and a total of 116 candidate YSOs in CrA are compiled. Based on these YSO candidates, the star formation rate is computed to be 12 M{sub sun} Myr{sup -1}, similar to that of the Lupus clouds. A clustering analysis was also performed, finding that the main cluster core, consisting of 68 members, is elongated (having an aspect ratio of 2.36), with a circular radius of 0.59 pc and mean surface density of 150 pc{sup -2}. In addition, we analyze outflows and jets in CrA by means of new CO and H{sub 2} data. We present 1.3 mm interferometric continuum observations made with the Submillimeter Array (SMA) covering R CrA, IRS 5, IRS 7, and IRAS 18595-3712 (IRAS 32). We also present multi-epoch H{sub 2} maps and detect jets and outflows, study their proper motions, and identify exciting sources. The Spitzer and ISAAC/VLT observations of IRAS 32 show a bipolar precessing jet, which drives a CO(2-1) outflow detected in the SMA observations. There is also clear evidence for a parsec-scale precessing outflow, which is east-west oriented and originates in the SMA 2 region and likely driven by SMA 2 or IRS 7A.

We developed a red-shelled family line and used suppression subtractive hybridization (SSH) to screen for differentially expressed genes in red- and non-red-shelled pearl oysters. We constructed forward and reverse cDNA subtractive libraries consisting of 2 506 and 797 clones, respectively. Among 343 randomly selected clones in the forward library, 304 sequences were identified in GenBank using BLASTx and BLASTn. Of the 304 sequences, 13 showed no similarity to known sequences and 291 were matched with known genes of the pearl oyster, including shematrin-1, shematrin-2, shematrin-6, shematrin-7, nacrein, nacrein-like protein, aspein for shell matrix protein, glycine-rich protein, mantle gene 5, 28S, EST00031, EST00036, 16S, and COI. In the reverse library, 7 clones were sequenced and analyzed by BLAST. Two sequences shared similarity with EST00036 from the P. fucata subtraction cDNA library, four with the P. fucata mitochondrial gene for 16S rRNA and 1 with P. fucata shematrin-2. We evaluated the expression of 12 genes from the forward library using RT PCR. Two sequences matched with 16S and COI so were considered to be false positives. The remaining 10 sequences were differentially expression in the red-shelled pearl oysters. Our results suggest that differential expression of these genes may be related to color variation in the red-shelled family line of the pearl oyster.

Such long-term profitability of short-sighted behavior cannot be evidenced when using a self-control paradigm (one which contrasts in a binary way sooner smaller and later larger payoffs) but becomes apparent when ecological patch-paradigms (replicating economic situations in which the main trade-off consists in staying on a food patch or leaving for another patch) are implemented.

Geographic patterns of genetic differentiation within the restricted range of the endangered Stephens' kangaroo rat Dipodomys stephensi.  

PubMed

Using mtDNA variation in the kangaroo rat Dipodomys stephensi, we found no support for the hypothesis that a species with an historically restricted range will exhibit low levels of genetic polymorphism and little genetic structure. Dipodomys stephensi has long been restricted to a few interior coastal valleys in southern California encompassing an area of approximately 70 x 40 km; however, we found high levels of genetic variation over much of its range and significant genetic structure both within and between regions. We also found evidence for a recent range expansion. Dipodomys stephensi is a federally endangered species that is separated from D. panamintinus, its presumed sister taxon, by a mountain range to the north. We assessed genetic variation by sequencing 645 bases of the mitochondrial d-loop from 61 individuals sampled from 16 locations across the species range and rooted their relationship using two D. panamintinus individuals. Despite its limited geographic range, the level of mtDNA variation in D. stephensi is comparable to that of other rodents, including that of the more widely distributed D. panamintinus. This variation revealed significant regional differentiation. The northern, central, and southern regions of the range differ in both the level and the distribution of genetic variation. Phylogenetic analysis revealed that the center of the range contains the most diversity of lineages, including the most basal. In this region and in the north, most haplotypes were found at only a single location (25/29), or at a pair of nearby locations (3/29). In addition, related haplotypes clustered geographically. These results are consistent with long-term demographic stability characterized by limited dispersal and high local effective population size. Further support for this conclusion is the finding of unique diversity in two northern peripheral populations, Norco and Potrero Creek (PC). However, in sharp contrast, one haplotype (CC) was found at five of 11 central and northern locations and comprised 18% of individuals sampled. The atypical distribution of the CC haplotype reflected a pattern seen more strongly in the southern region. Here the CC haplotype comprised 69% of the sample and was found at all five sampling locations. Consequently, the southern region had very low genetic variability. We propose that this dominance of CC was probably due to a local population bottleneck that occurred during a recent range expansion into the southern region. PMID:11475059

Bacillus thuringiensis toxin (Cry1Ab) has no direct effect on larvae of the green lacewing Chrysoperla carnea (Stephens) (Neuroptera: Chrysopidae).  

PubMed

Earlier studies have shown that larvae of the green lacewing predator Chrysoperla carnea are negatively affected when preying on lepidopteran larvae that had been fed with transgenic maize expressing the cry1Ab gene from Bacillus thuringiensis. To test whether the observed effects were directly caused by the Cry1Ab toxin, we have developed a bioassay which allows us to feed high concentrations of the toxin directly to the predator. The results of these feeding studies show no direct toxic effect of Cry1Ab on C. carnea larvae. The amount of toxin ingested by first instar C. carnea in the present study was found to be a factor 10,000 higher than the concentration ingested when feeding on Bt-reared lepidopteran larvae, a treatment that was previously shown to have a negative impact on the predator. In addition, feeding first instar C. carnea with the Cry1Ab toxin did not affect the utilisation of subsequently provided prey. Furthermore, the quality of the prey provided to first instars did not affect the sensitivity of second and third instar C. carnea to the Bt-toxin. The presented results strongly suggest that C. carnea larvae are not sensitive to Cry1Ab and that earlier reported negative effects of Bt-maize were prey-quality mediated rather than direct toxic effects. These results, together with the fact that lepidopteran larvae are not regarded as an important prey for C. carnea in the field, led us to conclude that transgenic maize expressing Cry1Ab poses a negligible risk for this predator.

Wrongful death claims. Harriton v Stephens. [2002] NSWSC 461. Edwards v Blomeley. [2002] NSWSC 460. Waller v James [2002] NSWSC 462.  

PubMed

Studdert J in all three cases went to great length to summarise the global judicial position of "wrongful life" claims. He did not, however, examine in great length how or whether "wrongful life" claims or "wrongful birth" claims are reconcilable with tort and common law principles. Although the cases identify the difficulty in assessing and quantifying damages, they do not directly address the strict legal principles which apply in the assessment of damages. The main conclusion of the three judgments was that no duty of care is owed to the plaintiff in these circumstances and, even if a duty could be established, the impossibility of quantifying damages and public policy considerations warrant the rejection of such a claim: "thus conscience does make cowards of us all." The significance of the decisions cannot be understand. The decisions deny recognition of "wrongful life" claims in circumstances where a disabled person has incurred injuries en ventre sa mere (in the mother's womb) as a result of infections contracted by a plaintiff's mother or genetic material passed on by a plaintiff's parents. Some countries have now legislated for the abolition of "wrongful life and birth" suits. In January 2002 the French legislature passed a Bill overturning the "wrongful life" decision of the Cour de Cassation in Perruche (17 November 2000). As the issue now falls for ultimate determination by the French Senate, the French pro-life movement continues to lobby for the prohibition of "wrongful birth" suits as well. Furthermore, eight States in the United States have prohibited either one or both actions and the State of Michigan prohibited both actions in 2001. It is likely that all three cases will be appealed. The appeal in Harriton will re-examine the viability of a "wrongful life" claim in Australia whereas the cases of Edwards and Waller still need to determine the "wrongful birth" claims brought by the plaintiffs' parents. It is likely that the latter two cases will not be determined until the High Court has considered the Queensland "wrongful birth" case of Melchior v Cattanach, expected to be late in 2002.

The whelk Nucella lapillus is the most abundant predator of intertidal mussels (Mytilus trossulus and M. edulis) on rocky shores along the Atlantic coast of Nova Scotia, Canada. Environmental differences among intertidal habitats, such as tidepools and emergent rock, may influence the intensity of predation and its effect on community structure.

A comment on: `TitaniQ under pressure: the effect of pressure and temperature on the solubility of Ti in quartz', by Jay B. Thomas, E. Bruce Watson, Frank S. Spear, Philip T. Shemella, Saroj K. Nayak and Antonio Lanzirotti  

NASA Astrophysics Data System (ADS)

Trace concentrations of Ti in quartz are used to indicate the pressure and temperature conditions of crystallization in the `TitaniQ' geothermobarometer of Thomas et al. (Contrib Miner Petrol 160:743-759, 2010). It utilises the partitioning of Ti into quartz as an indicator of the pressures and/or temperatures of crystal growth. For a given value of TiO2 activity in the system, if temperatures are inferred to ±20 °C, pressure is constrained to ±1 kbar and vice versa. There are significant contrasts, however, between the conclusions from TitaniQ and those for natural quartz (as well as other mineral phases) in volcanic rocks. Application of the TitaniQ model to quartz from the 27 ka Oruanui and 760 ka Bishop high-silica rhyolites, where the values of T, P and TiO2 activity are constrained by other means (Fe-Ti oxide equilibria, melt inclusion entrapment pressures in gas-saturated melts, melt and amphibole compositions), yields inconsistent results. If realistic values are given to any two of these three parameters, then the value of the third is wholly unrealistic. The model yields growth temperatures at or below the granite solidus, pressures in the lower crust or upper mantle, or TiO2 activities inconsistent with the mineralogical and chemical compositions of the magmas. CL imagery and measurements of Ti (and other elements) in quartz are of great value in showing the growth histories and changes in conditions experienced by crystals, but direct linkages to P, T conditions during crystal growth cannot be achieved.

A Review of Self-Help Skills for People with Autism: A Systematic Teaching Approach, by Stephen R. Anderson, Amy L. Jablonski, Marcus L. Thomeer, and Vicki Madaus Knapp  

PubMed Central

An overriding goal for all children on the autism spectrum is for them to function independently in their completion of daily routine skills, such as getting dressed, eating, and using the toilet. Unfortunately, most published curricula and teaching guidelines have focused on communication and academic skills rather than on self-help skills. The book, Self-help skills for people with autism: A systematic teaching approach, by Anderson and colleagues, provides parents and professionals with a systematic method for planning and teaching these valuable skills using scientifically proven methods of applied behavior analysis (ABA). This book is reviewed in terms of the strengths and limitations of the content, as well as its importance as a practical educational tool for assisting those who train individuals with autism.

Monozygotic twins concordant for autism and hyperlexia.  

PubMed

The authors describe male monozygotic twins, Jon and Jay, who are concordant for autism and hyperlexia. Autism and mental retardation were diagnosed at the age of 2 years 5 months. Jay was the more advanced twin in motor co-ordination, attention span and receptive abilities, but had frequent tantrums. When psychologically assessed at 7 years 2 months, Jon showed borderline/severe mental retardation on the measure of non-verbal intelligence and Jay was moderately retarded. Their receptive language age was greater than their expressive language age: Jon's speech was less mature but more communicative and Jay's was perseverative and ritualistic. Even though Jon was the more mentally retarded twin, Jay was the more autistic in some behavioral aspects. These twins highlight the relationship between autism and hyperlexia. PMID:3169393

Ring Around the Sky  

NASA Astrophysics Data System (ADS)

Gould's Belt, the most prominent starry feature in the Sun's neighborhood, is a zone of large supergiant stars including the Orion constellation; the bright stars of Canis Major, the Southern Cross, Centaurus, and Lupus; and the brightest stars of the Pupis, Vela, and Carina constellations. Its most prominent feature is its 20-degree tilt to the plane of the Milky Way. Gould's Belt was first noticed in 1847 by Englishman John F. W. Herschel while observing from the Cape of Good Hope in South Africa. Later, Benjamin A. Gould, the first American to earn a doctoral degree in astronomy and the founder of The Astronomical Journal, traced the belt around the entire sky. More recent studies of Gould's Belt show evidence of more than just superstars. When massive stars like those in Gould's Belt explode, they leave behind pulsars and black holes. In the 1990's several dozen gamma-ray sources were discovered to track along the path of Gould's Belt around the sky, possible evidence of the explosion of brilliant stars at an earlier time. X-ray studies suggest that the belt may actually be a disk.

Skeletal muscle gene expression after myostatin knockout in mature mice Address for reprint requests and other correspondence: S. Welle, Univ. of Rochester Medical Center, 601 Elmwood Ave., Box 693, Rochester, NY 14642 (e-mail: stephen_welle@urmc.rochester.edu).  

PubMed Central

There is much interest in developing anti-myostatin agents to reverse or prevent muscle atrophy in adults, so it is important to characterize the effects of reducing myostatin activity after normal muscle development. For assessment of the effect of loss of myostatin signaling on gene expression in muscle, RNA from mice with postdevelopmental myostatin knockout was analyzed with oligonucleotide microarrays. Myostatin was undetectable in muscle within 2 wk after Cre recombinase activation in 4-month-old male mice with floxed myostatin genes. Three months after myostatin depletion, muscle mass had increased 26% (vs. 2% after induction of Cre activity in mice with normal myostatin genes), at which time the expression of several hundred genes differed in knockout and control mice at nominal P < 0.01. In contrast to previously reported effects of constitutive myostatin knockout, postdevelopmental knockout did not downregulate expression of genes encoding slow isoforms of contractile proteins or genes encoding proteins involved in energy metabolism. Several collagen genes were expressed at 20–50% lower levels in the myostatin-deficient muscles, which had ?25% less collagen than normal muscles as reflected by hydroxyproline content. Most of the other genes affected by myostatin depletion have not been previously linked to myostatin signaling. Gene set enrichment analysis suggested that Smads are not the only transcription factors with reduced activity after myostatin depletion. These data reinforce other evidence that myostatin regulates collagen production in muscle and demonstrate that many of the previously reported effects of constitutive myostatin deficiency do not occur when myostatin is knocked out in mature muscles.
