Stephen Jay Gould as Historian of Science and Scientific Historian, Popular Scientist and Scientific Popularizer  

Microsoft Academic Search

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

Claiming Darwin: Stephen Jay Gould in contests over evolutionary orthodoxy and public perception, 1977-2002.  

PubMed

This article analyzes the impact of the resurgence of American creationism in the early 1980s on debates within post-synthesis evolutionary biology. During this period, many evolutionists criticized Harvard biologist Stephen Jay Gould for publicizing his revisions to traditional Darwinian theory and opening evolution to criticism by creationists. Gould's theory of punctuated equilibrium was a significant source of contention in these disputes. Both he and his critics, including Richard Dawkins, claimed to be carrying the mantle of Darwinian evolution. By the end of the 1990s, the debate over which evolutionary thinkers were the rightful heirs to Darwin's evolutionary theory was also a conversation over whether Darwinism could be defended against creationists in the broader cultural context. Gould and others' claims to Darwin shaped the contours of a political, religious and scientific controversy. PMID:24457049

Science, Intelligence, and Educational Policy: The Mismeasure of Frankenstein (with Apologies to Mary Shelley and Stephen Jay Gould).

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.

Gould's Belt  

E-print Network

The local velocity patterns of star forming regions, young OB stars, nearby OB associations, atomic and molecular gas are confronted with models of an expanding region. We test free expansion from a point or from a ring, expanding 2D shell, and expanding 3D belt with abrupt or gradual energy injection snow-plowing the ambient medium with or without the drag forces including fragmentation and porosity of the medium. There is no agreement on the expansion time, which varies from 30 - 100 Myr. The inclination of the Gould belt is not explained by the above models of expansion. An oblique impact of a high velocity cloud may explain it, but the observed velocity pattern is difficult to reproduce. The Gould's belt may be one of the many structures resulting from shell-shell collisions in the galactic plane. The origin of the Gould's belt may be connected to instabilities in the curling gas flows downstream from the Galaxy spiral arms, forming ISM clouds and star formation complexes.

The Gould's Belt Distances Survey  

E-print Network

Very Long Baseline Interferometry (VLBI) observations can provide the position of compact radio sources with an accuracy of order 50 micro-arcseconds. This is sufficient to measure the trigonometric parallax and proper motions of any object within 500 pc of the Sun to better than a few percent. Because they are magnetically active, young stars are often associated with compact radio emission detectable using VLBI techniques. Here we will show how VLBI observations have already constrained the distance to the most often studied nearby regions of star-formation (Taurus, Ophiuchus, Orion, etc.) and have started to provide information on their internal structure and kinematics. We will then briefly describe a large project (called The Gould's Belt Distances Survey) designed to provide a detailed view of star-formation in the Solar neighborhood using VLBI observations.

CO depletion in the Gould Belt clouds  

NASA Astrophysics Data System (ADS)

We present a statistical comparison of CO depletion in a set of local molecular clouds within the Gould Belt using Sub-millimetre Common User Bolometer Array (SCUBA) and Heterodyne Array Receiver Programme (HARP) data. This is the most wide-ranging study of depletion thus far within the Gould Belt. We estimate CO column densities assuming local thermodynamic equilibrium and, for a selection of sources, using the radiative transfer code RADEX in order to compare the two column density estimation methods. High levels of depletion are seen in the centres of several dust cores in all the clouds. We find that in the gas surrounding protostars, levels of depletion are somewhat lower than for starless cores with the exception of a few highly depleted protostellar cores in Serpens and NGC 2024. There is a tentative correlation between core mass and core depletion, particularly in Taurus and Serpens. Taurus has, on average, the highest levels of depletion. Ophiuchus has low average levels of depletion which could perhaps be related to the anomalous dust grain size distribution observed in this cloud. High levels of depletion are often seen around the edges of regions of optical emission (Orion) or in more evolved or less dynamic regions such as the bowl of L1495 in Taurus and the north-western region of Serpens.

Space cowboys odyssey: beyond the Gould Belt  

E-print Network

We present our new advanced model for population synthesis of close-by cooling NSs. Detailed treatment of the initial spatial distribution of NS progenitors and a detailed ISM structure up to 3 kpc give us an opportunity to discuss the strategy to look for new isolated cooling NSs. Our main results in this respect are the following: new candidates are expected to be identified behind the Gould Belt, in directions to rich OB associations, in particular in the Cygnus-Cepheus region; new candidates, on average, are expected to be hotter than the known population of cooling NS. Besides the usual approach (looking for soft X-ray sources), the search in 'empty' $\\gamma$-ray error boxes or among run-away OB stars may yield new X-ray thermally emitting NS candidates.

The San Francisco Museum of Modern Art (SGFMOMA) has mounted a retrospective exhibition of the work of Jay DeFeo (1929-1989), who was active in the Bay area from the 1950s to the 1980s. The show will be on view at SFMOMA until February 3, 2013; on the website, select the Related Multimedia tab to see a selection of audio and video resources on DeFeo. Possibly most moving is Bruce Conner's film on DeFeo's most famous painting, "The Rose" (1958ââ‰ÂÂ66). 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."

A Gould-Belt-like structure in M 83  

NASA Astrophysics Data System (ADS)

VLT archive observations of M 83 are used to study a complex in the disk of that galaxy that shows a remarkable similarity to the Gould Belt. The complex is clearly separated from the overall spiral pattern of the galaxy. It is several hundred parsecs across, and is resolved into several tens of point sources, thus looking much as the Gould Belt should if observed from above the galactic plane. The point sources are likely to be bright, Trapezium-like clusters, or compact OB associations. Many of them display H? emission, whose luminosity is estimated to be of the order of that of the Orion nebula. The integrated absolute B magnitude of this complex and the Gould Belt are found to be comparable. The blue colors of some of the members, the abundance of H? emission, and the lack of any apparent distortion of the shape of the complex due to galactic shear all argue for a very young age. The similarity in size, location with respect to the spiral pattern of the host galaxy, contents, age, and overall luminosity of the M 83 complex studied here strongly argue for a similarity between the two structures.

Beloit College: Jay "Ding" Darling Collection  

NSDL National Science Digital Library

Jay "Ding" Darling was a wildlife enthusiast who was perhaps better known for his Pulitzer Prize-winning political cartoons. Today, a National Wildlife Refuge in Florida bears his name and this fine digital collection pays tribute to his time as a Beloit College student. During his student years, Darling created illustrations for the student yearbook (the Codex) and newspapers like the Des Moines Register. The online collection has 78 items, including letters, cartoons, draft drawings, and so on. One of the most interesting items here is a letter written by Darling in 1959 that recounts the time he met Joseph Stalin. Also, his illustrations for the 1899 Codex are truly delightful. They include a creative illustration of the baseball team's schedule and a rather humorous illustration of the "college graveyard," complete with tombstones for past events, such as the junior prom.

Geographic variation in Mexican jays (Aphelocoma ultramarina): local differentiation, polyphyly or hybridization?  

PubMed

Studies of genetic variation within highly variable taxa can provide valuable insight into the factors influencing biological diversification. We examined six microsatellite loci, a nuclear intron and the mitochondrial control region to determine if the Mexican jay subspecies Aphelocoma ultramarina couchii and A. u. potosina have hybridized with western scrub-jays (A. californica). We suspected hybridization because these Mexican Jay populations resemble scrub-jays in several traits. We sampled six Mexican jay (N = 105) and four scrub-jay (N = 78) populations. Suspected hybrid Mexican Jay populations did not share any mitochondrial types or intron alleles with scrub-jays. All microsatellite alleles found in the suspected hybrid Mexican jay populations are also found in the control Mexican jay populations. Genetic distance-based trees from microsatellites supported reciprocal monophyly of Mexican jays and scrub-jays with bootstrap support > 80%. We randomized genotypes among populations to test scenarios consistent with hybridization. In some areas where Mexican jays and scrub-jays occur in sympatry or geographical proximity, randomization tests yield results expected under hybridization (100% support for seven of nine scenarios). However, these populations were not the primary candidates for hybridization based on phenotype. Even if low-level hybridization did occur, hybridization does not appear to be the main reason some Mexican jay populations resemble scrub-jays more than others. The scrub-jay-like traits in these populations may be due to drift, adaptation or plasticity. Alternatively, ancient hybridization, followed by selection for scrub-jay like traits in some Mexican jay populations, might have given rise to the observed variation. PMID:15315684

Western scrub jays (Aphelocoma californica) hide food and rely on spatial memory to recover their caches at a later date. To do this cache-and-recovery, they can use both spatial and site-specific cues. I examined these cues in an experimental setting. The experiment established that scrub jays, like other food storers, prefer to rely on the location of the caching tray

The Gould's Belt Molecular Clouds: Consequences of a Superbubble  

NASA Astrophysics Data System (ADS)

I present evidence that a large OB association (Cas-Tau), centered on ? Per open cluster, formed about 40 million years ago. The kinetic energy deposited by the massive stars of Cas-Tau generated gravitational instabilities in the Interstellar Medium (ISM). These instabilities became the Giant Molecular Clouds (GMCs) associated with the nearby (< 2 kiloparsecs) star forming regions in Orion, Scorpius-Centaurus, Perseus, Lacertae and the rest of the Gould's Belt stars. The creation of GMCs associated with star forming regions is a long standing, unsolved problem in modern astronomy. The popular theories (Jeans type instabilities in a rotating disk) produce condensations that are at least an order of magnitude too massive to be the seeds of the galactic Giant Molecular Cloud population, and on timescales far longer than the lifetimes of GMCs. Expanding superbubbles (kiloparsec scaled, multiple supernova remnants that form around large clusters) in the ISM sweep up 'supershells' of higher density material. These shells can theoretically become gravitationally unstable over appropriate timescales to GMC mass instabilities. Observational evidence in support of this theory has been lacking until now. The distribution and dynamics of molecular gas predicted by supershell instability theory is clearly evident in my study of local molecular gas using a galactic plane 12CO survey. Results demonstrate the earlier formation (compared to other nearby regions) of the oldest star forming region in Gould's Belt (Orion) is due to the interaction of the Gould's Belt Supershell with the recently discovered nearby supershell GSH238+00+09 (the Vela Supershell). I also discuss possible origins of the Taurus clouds, which are well inside the large low-density volume swept out by the Cas-Tau association superbubble. This work was supported in part by the Center for Astrophysics and Space Astronomy (CASA) at the University of Colorado.

Level II scour analysis for Bridge 22 (JAY-TH00400022) on Town Highway 40, crossing Jay Branch, Jay, Vermont  

USGS Publications Warehouse

8). A Level II study is a basic engineering analysis of the site, including a quantitative analysis of stream stability and scour (U.S. Department of Transportation, 1993). Results of a Level I scour investigation also are included in Appendix E of this report. A Level I investigation provides a qualitative geomorphic characterization of the study site. Information on the bridge, gleaned from Vermont Agency of Transportation (VTAOT) files, was compiled prior to conducting Level I and Level II analyses and is found in Appendix D. The site is in the Green Mountain section of the New England physiographic province in northern Vermont. The 2.15-mi2 drainage area is in a predominantly rural and forested basin. In the vicinity of the study site, the surface cover is primarily pasture on the upstream and downstream left overbank while the immediate banks have dense woody vegetation. The downstream right overbank of the bridge is forested. In the study area, Jay Branch Tributary has an incised, sinuous channel with a slope of approximately 0.02 ft/ft, an average channel top width of 26 ft and an average bank height of 3 ft. The channel bed material ranges from gravel to cobble with a median grain size (D50) of 40.5 mm (0.133 ft). The geomorphic assessment at the time of the Level I and Level II site visit on June 7, 1995, indicated that the reach was stable. The Town Highway 40 crossing of Jay Branch Tributary is a 27-ft-long, two-lane bridge consisting of one 25-foot steel-beam span (Vermont Agency of Transportation, written communication, March 6, 1995). The opening length of the structure parallel to the bridge face is 23.5 ft. The bridge is supported by vertical, concrete abutments with wingwalls. The channel skew and the opening-skew-to-roadway are zero degrees. The scour counter-measures at the site included type-2 stone fill (less than 36 inches diameter) at the upstream end of the left and right abutments, at the upstream right wingwall, and at the downstream left wingwall. There was also type-3 stone fill (less than 48 inches diameter) at the upstream left and downstream right wingwall. Additional details describing conditions at the site are included in the Level II Summary and Appendices D and E. Scour depths and recommended rock rip-rap sizes were computed using the general guidelines described in Hydraulic Engineering Circular 18 (Richardson and others, 1995). Total scour at a highway crossing is comprised of three components: 1) long-term streambed degradation; 2) contraction scour (due to accelerated flow caused by a reduction in flow area at a bridge) and; 3) local scour (caused by accelerated flow around piers and abutments). Total scour is the sum of the three components. Equations are available to compute depths for contraction and local scour and a summary of the results of these computations follows. Contraction scour for all modelled flows ranged from 0.7 to 1.1 ft. The worst-case contraction scour occurred at the 500-year discharge. Left abutment scour ranged from 4.6 to 4.9 ft. The worst-case left abutment scour occurred at the 100-year discharge. Right abutment scour ranged from 4.0 to 5.0 ft. The worst-case right abutment scour occurred at the 500-year discharge. Additional information on scour depths and depths to armoring are included in the section titled “Scour Results”. Scoured-streambed elevations, based on the calculated scour depths, are presented in tables 1 and 2. A cross-section of the scour computed at the bridge is presented in figure 8. Scour depths were calculated assuming an infinite depth of erosive material and a homogeneous particle-size distribution. It is generally accepted that the Froehlich equation (abutment scour) gives “excessively conservative estimates of scour depths” (Richardson and others, 1995, p. 47). Usually, computed scour depths are evaluated in combination with other information i

Remeasuring man.  

PubMed

Samuel George Morton (1799-1851) was the most highly regarded American scientist of the early and middle 19th century. Thanks largely to Stephen Jay Gould's book The Mismeasure of Man, Morton's cranial capacity measurements of different races is now held up as a prime example of and cautionary tale against scientific racism. A team of anthropologists recently reevaluated Morton's work and argued that it was Gould, not Morton, who was biased in his analysis. This article is a reexamination of the Morton and Gould controversy. It argues that most of Gould's arguments against Morton are sound. Although Gould made some errors and overstated his case in a number of places, he provided prima facia evidence, as yet unrefuted, that Morton did indeed mismeasure his skulls in ways that conformed to 19th century racial biases. Gould's critique of Morton ought to remain as an illustration of implicit bias in science. PMID:24761929

Testosterone and social and reproductive behaviour in Aphelocoma jays.  

PubMed

When there is a direct relationship between testosterone level and payoff in reproductive success through aggression, testosterone levels should be elevated. Elevated testosterone, however, has fitness costs, particularly a decreased tendency to display parental care. Thus the pattern of testosterone secretion in males should vary with the social and mating system. Western scrub-jays, Aphelocoma californica woodhouseii, form monogamous pairs on territories during the breeding season. Mexican jays, A. ultramarina, live in large, stable groups and up to five females within a group attempt nesting each spring. In both species, testosterone levels rose rapidly in March and peak levels did not differ. Elevated testosterone levels were only observed for about 3 weeks in the monogamous western scrub-jay, but were observed into May in Mexican jays, a reflection of prolonged opportunity for males to mate with multiple females and continual interaction with other competing males. In Mexican jays, nonbreeding yearlings had lower testosterone levels than all other age groups. Testosterone in males owning nests did not differ from that in other adult males, many of whom engage in extrapair fertilizations. Testosterone was elevated throughout the incubation phase, but was significantly lower when chicks were present in any nest in the group. Nearly all birds in the group fed all chicks. These observations support the hypothesis that testosterone is elevated when male-male competition is frequent and mating opportunities depend on the outcome of that competition, and testosterone is decreased when the necessity for parental or alloparental care would make its effects deleterious.

Crossing the Gould Belt in the Orion vicinity  

NASA Astrophysics Data System (ADS)

Context. The recent star formation history in the solar vicinity is not yet well constrained, and the real nature of the so-called Gould Belt is still unclear. Aims: We present a study of the large-scale spatial distribution of 6482 ROSAT All-Sky Survey (RASS) X-ray sources in approximately 5000 deg2 in the general direction of Orion. We examine the astrophysical properties of a sub-sample of ~100 optical counterparts, using optical spectroscopy. This sub-sample is then used to investigate the space density of the RASS young star candidates by comparing X-ray number counts with Galactic model predictions. Methods: The young star candidates were selected from the RASS using X-ray criteria. We characterize the observed sub-sample in terms of spectral type, lithium content, radial and rotational velocities, and iron abundance. A population synthesis model is then applied to analyze the stellar content of the RASS in the studied area. Results: We find that stars associated with the Orion star-forming region, as expected, do show a high lithium content. As in previous RASS studies, a population of late-type stars with lithium equivalent widths larger than that of the Pleiades stars of the same spectral type (hence younger than ~70-100 Myr) is found widely spread over the studied area. Two new young stellar aggregates, namely "X-ray Clump 0534+22" (age ~ 2-10 Myr) and "X-ray Clump 0430-08" (age ~ 2-20 Myr), are also identified. Conclusions: The spectroscopic follow-up and comparison with Galactic model predictions reveal that the X-ray selected stellar population in the general direction of Orion is characterized by three distinct components, namely the clustered, the young dispersed, and the widespread field populations. The clustered population is mainly associated with regions of recent or ongoing star formation and correlates spatially with molecular clouds. The dispersed young population follows a broad lane that apparently coincides spatially with the Gould Belt, while the widespread population consists primarily of active field stars older than 100 Myr. We expect the still "bi-dimensional" picture emerging from this study to grow in depth as soon as the distance and the kinematics of the studied sources will become available from the future Gaia mission. Based on ROSAT All-Sky Survey data, low-resolution spectroscopic observations performed at the European Southern Observatory (Chile; Program 05.E-0566) and at the Observatorio Astronómico Nacional de San Pedro Mártir (Mexico), and high-resolution spectroscopic observations carried out at the Calar Alto Astronomical Observatory (Spain).Table 4 and Appendix A are only available in electronic form at http://www.aanda.org

Pilfering Eurasian jays use visual and acoustic information to locate caches.  

PubMed

Pilfering corvids use observational spatial memory to accurately locate caches that they have seen another individual make. Accordingly, many corvid cache-protection strategies limit the transfer of visual information to potential thieves. Eurasian jays (Garrulus glandarius) employ strategies that reduce the amount of visual and auditory information that is available to competitors. Here, we test whether or not the jays recall and use both visual and auditory information when pilfering other birds' caches. When jays had no visual or acoustic information about cache locations, the proportion of available caches that they found did not differ from the proportion expected if jays were searching at random. By contrast, after observing and listening to a conspecific caching in gravel or sand, jays located a greater proportion of caches, searched more frequently in the correct substrate type and searched in fewer empty locations to find the first cache than expected. After only listening to caching in gravel and sand, jays also found a larger proportion of caches and searched in the substrate type where they had heard caching take place more frequently than expected. These experiments demonstrate that Eurasian jays possess observational spatial memory and indicate that pilfering jays may gain information about cache location merely by listening to caching. This is the first evidence that a corvid may use recalled acoustic information to locate and pilfer caches. PMID:24889656

Planning for the future by western scrub-jays.  

PubMed

Knowledge of and planning for the future is a complex skill that is considered by many to be uniquely human. We are not born with it; children develop a sense of the future at around the age of two and some planning ability by only the age of four to five. According to the Bischof-Köhler hypothesis, only humans can dissociate themselves from their current motivation and take action for future needs: other animals are incapable of anticipating future needs, and any future-oriented behaviours they exhibit are either fixed action patterns or cued by their current motivational state. The experiments described here test whether a member of the corvid family, the western scrub-jay (Aphelocoma californica), plans for the future. We show that the jays make provision for a future need, both by preferentially caching food in a place in which they have learned that they will be hungry the following morning and by differentially storing a particular food in a place in which that type of food will not be available the next morning. Previous studies have shown that, in accord with the Bischof-Köhler hypothesis, rats and pigeons may solve tasks by encoding the future but only over very short time scales. Although some primates and corvids take actions now that are based on their future consequences, these have not been shown to be selected with reference to future motivational states, or without extensive reinforcement of the anticipatory act. The results described here suggest that the jays can spontaneously plan for tomorrow without reference to their current motivational state, thereby challenging the idea that this is a uniquely human ability.

Western scrub-jays conceal auditory information when competitors can hear but cannot see.  

PubMed

Western scrub-jays (Aphelocoma californica) engage in a variety of cache-protection strategies to reduce the chances of cache theft by conspecifics. Many of these strategies revolve around reducing visual information to potential thieves. This study aimed to determine whether the jays also reduce auditory information during caching. Each jay was given the opportunity to cache food in two trays, one of which was filled with small pebbles that made considerable noise when cached in ('noisy' tray), whereas the other one contained soil that made little detectable noise when cached in ('quiet' tray). When the jays could be heard, but not seen, by a competitor, they cached proportionally less food items in the 'noisy' substrate than when they cached alone in the room, or when they could be seen and heard by competitors. These results suggest that western scrub-jays know when to conceal auditory information, namely when a competitor cannot see but can hear the caching event. PMID:19605383

However, when the jays had the choice of caching items in 2 different locations or during 2 successive episodes, and only 1 of each was always rewarded at recovery, they rapidly learned to cache in the rewarded location or episode. When the jays had learned during training trials that their caches were always moved to 1 of 2 locations they did not cache in, then on the test trial they cached in the location that had been previously rewarded. To test whether these jays avoided the location in which their caches had been pilfered or chose the rewarded location, the procedure was repeated to include a 3rd location that was never rewarded. The jays avoided the pilfered location but cached equally in the rewarded and nonrewarded locations. PMID:17924785

Food caching by western scrub-jays (Aphelocoma californica) is sensitive to the conditions at recovery.  

PubMed

Western scrub-jays (Aphelocoma californica) cached perishable and nonperishable food items, which they could recover after both short and long retention intervals. When perishable items were always degraded at recovery, jays decreased the number of perishable items cached and increased their caching of nonperishable items, relative to a control group whose caches were always fresh at recovery. Jays reduced the number of nonperishable items cached, however, when highly preferred food items were degraded only after the long retention intervals. The findings are discussed in terms of the role of retrospective and prospective processes in the control of caching. PMID:15839770

We detected 374 and 354 sources at 4.5 and 7.5 GHz, respectively. Of these, 148 are associated with previously known young stellar objects (YSOs). Another 86 sources previously unclassified at either optical or infrared wavelengths exhibit radio properties that are consistent with those of young stars. The overall properties of our sources at radio wavelengths such as their variability and radio to X-ray luminosity relation are consistent with previous results from the Gould's Belt Survey. Our detections provide target lists for follow-up Very Long Baseline Array radio observations to determine their distances as YSOs are located in regions of high nebulosity and extinction, making it difficult to measure optical parallaxes.

Habitat model for the Florida Scrub Jay on John F. Kennedy Space Center  

NASA Technical Reports Server (NTRS)

The Florida Scrub Jay is endemic to Florida. The John F. Kennedy Space Center (KSC) provides habitat for one of the three largest populations of the Florida Scrub Jay. This threatened bird occupies scrub, slash pine flatwoods, disturbed scrub, and coastal strand on KSC. Densities of Florida Scrub Jays were shown to vary with habitat characteristics but not necessarily with vegetation type. Relationships between Florida Scrub Jay densities and habitat characteristics were used to develop a habitat model to provide a tool to compare alternative sites for new facilities and to quantify environmental impacts. This model is being tested using long term demographic studies of colorbanded Florida Scrub Jays. Optimal habitat predicted by the model has greater than or equal to 50 percent of the shrub canopy comprised of scrub oaks, 20-50 percent open space or scrub oak vegetation within 100 m of a ruderal edge, less than or equal to 15 percent pine canopy cover, a shrub height of 120-170 cm, and is greater than or equal to 100 m from a forest. This document reviews life history, social behavior, food, foraging habitat, cover requirements, characteristics of habitat on KSC, and habitat preferences of the Florida Scrub Jay. Construction of the model and its limitations are discussed.

They also learn that one of the best indicators of evolution is not the examples of perfect adaptations, but of the relatively imperfect contrivances, structures modified and used for functions quite different than the ancestral functions of those same structures.

Apparent predation by Gray Jays, Perisoreus canadensis, on Long-toed Salamanders, Ambystoma macrodactylum, in the Oregon Cascade Range  

USGS Publications Warehouse

We report observations of Gray Jays (Perisoreus canadensis) appearing to consume larval Long-toed Salamanders (Ambystoma macrodactylum) in a drying subalpine pond in Oregon, USA. Corvids are known to prey upon a variety of anuran amphibians, but to our knowledge, this is the first report of predation by any corvid on aquatic salamanders. Long-toed Salamanders appear palatable to Gray Jays, and may provide a food resource to Gray Jays when salamander larvae are concentrated in drying temporary ponds.

Radio-Loud and Radio-Quiet Gamma-Ray Pulsars from the Galaxy and the Gould Belt  

NASA Astrophysics Data System (ADS)

We present results of a population synthesis study of radio-loud and radio-quiet ?-ray pulsars from the Galactic plane and the Gould Belt. The simulation includes the Parkes multibeam pulsar survey, realistic beam geometries for radio and ?-ray emission from neutron stars and the new electron density model of Cordes and Lazio. Normalizing to the number of radio pulsars observed by a set of nine radio surveys, the simulation suggests a neutron star birth rate of 1.4 neutron stars per century in the Galactic plane. In addition, the simulation predicts 19 radio-loud and 7 radio-quiet ?-ray pulsars from the plane that EGRET should have observed as point sources. Assuming that during the last 5 Myr the Gould Belt produced 100 neutron stars, only 10 of these would be observed as radio pulsars with three radio-loud and four radio-quiet ?-ray pulsars observed by EGRET. These results are in general agreement with the recent number of about 25 EGRET error boxes that contain Parkes radio pulsars. Since the Gould Belt pulsars are relatively close by, the selection of EGRET radio-quiet ?-ray pulsars strongly favors large impact angles, ?, in the viewing geometry where the off-beam emission from curvature radiation provides the ?-ray flux. Therefore, the simulated EGRET radioquiet ?-ray pulsars, being young and nearby, most closely reflect the current shape of the Gould Belt suggesting that such sources may significantly contribute to the EGRET unidentified ?-ray sources correlated with the Gould Belt.

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

The imprint of Gould's Belt on the local cosmic-ray electron spectrum  

NASA Astrophysics Data System (ADS)

Recent analyses have shown that if the sources of cosmic-rays are discrete, as are supernova remnants, then the spectra of cosmic-ray electrons vary greatly with location and time and the locally measured electron spectrum may be not representative of the electron spectra elsewhere in the Galaxy. We have continued the earlier studies by investigating the impact of the star forming region Gould's Belt on the local electron spectrum at GeV to TeV energies. Our results indicate that if the electron sources in Gould's Belt are continous, the local electron spectrum would be slightly hardened with a spectral index increase of Delta s~ 0.07 due to the higher SN rate in the Belt. If the electron sources are discrete, which is the more probable case, the local electron spectrum above ~ 30 GeV is variable with similar amplitude as without Gould's Belt. By the method of Monte Carlo, we have also studied the correlation of the local electron flux with that in nearby molecular cloud complexes. The high energy electron flux above 30 GeV near the Orion, Monoceros, Cassiopeia, Cepheus, and Perseus clouds does not vary in coordination with the local flux, but a correlation between the electron flux in the Taurus and Ophiuchus clouds and that in solar vicinity is indicated by our study, implying that the spatial correlation length is of the order of 200 pc at electron energies of 100 GeV and higher. This would permit hard gamma -ray spectra from inverse Compton scattering to be produced in the more distant clouds, in agreement with the GeV excess observed towards Orion and Monoceros, without affecting the emissivity spectra of the very nearby clouds as in Taurus and Ophiuchus.

Isolation and characterization of microsatellite loci in the western pearlshell mussel, Margaritifera falcata (Gould).  

PubMed

Ten microsatellite loci were isolated from the western pearlshell, Margaritifera falcata (Gould, 1850) and characterized in populations from Washington and Montana, USA. We also assessed eight microsatellite loci developed in M. margaritifera, two of which showed utility. Both of our test populations showed significant heterozygote deficiencies at most loci, consistent with a hermaphroditic life history. Populations differed markedly with respect to allelic richness, allele frequencies and numbers of identical multilocus genotypes. This panel of loci should prove useful in describing gene flow and genetic diversity patterns among M. falcata populations, information that should aid future conservation efforts. PMID:21564817

Cache protection strategies by western scrub-jays (Aphelocoma californica): hiding food in the shade.  

PubMed

In the presence of conspecifics, food-caching western scrub-jays (Aphelocoma californica) implement a variety of strategies to reduce the chances of cache theft. This experiment aimed to determine whether the jays could exploit an environmental variable, the level of ambient light, to reduce the transfer of visual information to potential pilferers. Each jay was allowed to cache non-degradable food in two trays, one of which was well lit, whereas the other was in shadow. In some trials the birds cached in private and in others they were observed; however, they always recovered their caches in private. When observed the jays preferentially cached in the shaded tray, whereas both trays were used equally when caching in private. By caching in shaded sites, the quality and transfer of visual information available to the observer may be reduced, thereby making the location of cache sites less certain. These results suggest that western scrub-jays may selectively cache in the shade as a strategy to reduce the chance of cache theft by observing conspecifics. PMID:15801583

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.

No evidence of temporal preferences in caching by Western scrub-jays (Aphelocoma californica)?  

PubMed Central

Humans and other animals often favour immediate gratification over long-term gain. Primates, including humans, appear more willing to wait for rewards than other animals, such as rats or pigeons. Another group displaying impressive patience are the corvids, which possess large brains and show sophisticated cognitive abilities. Here, we assess intertemporal choice in one corvid species, the Western scrub-jay (Aphelocoma californica). These birds cache food for future consumption and respond flexibly to future needs. Cache-theft and cache-degradation are time-dependent processes in scrub-jay ecology that might necessitate sensitivity to delays between caching and retrieval. We adopt a caching paradigm with delays of up to 49 h. Across two experiments we find no evidence of a preference for earlier recovery. We highlight the possibility that, although scrub-jays can discriminate between the present and the future, they may not understand how far into the future an event will occur. PMID:24378212

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

Off-Beam Gamma-Ray Pulsars and Unidentified EGRET Sources in the Gould Belt  

E-print Network

We investigate whether gamma-ray pulsars viewed at a large angle to the neutron star magnetic pole could contribute to the new population of galactic unidentified EGRET sources associated with the Gould Belt. The faint, soft nature of these sources is distinctly different from both the properties of unidentified EGRET sources along the galactic plane and of the known gamma-ray pulsars. We explore the possibility, within the polar cap model, that some of these sources are emission from pulsars seen at lines of sight that miss both the bright gamma-ray cone beams and the radio beam. The off-beam gamma-rays come from high-altitude curvature emission of primary particles, are radiated over a large solid angle and have a much softer spectrum than that of the main beams. We estimate that the detectability of such off-beam emission is about a factor of 4-5 higher than that of the on-beam emission. At least some of the radio-quiet Gould Belt sources detected by EGRET could therefore be such off-beam gamma-ray pulsars. GLAST should be able to detect pulsations in most of these sources.

Not only size matters: Acorn selection by the European jay ( Garrulus glandarius)  

NASA Astrophysics Data System (ADS)

A strong selection for acorn characteristics is expected to have evolved in the mutualistic relationship between the European jay ( Garrulus glandarius) and the oak ( Quercus spp.). Bossema's pioneer work suggested that jays do not select acorns randomly, but rather they preferentially select some size and species. Preference for some seeds over others may have implications on plant community dynamics by conferring advantages (or disadvantages) on the selected (avoided) seed characteristics. In this paper we test to what extent jays select acorns by species and/or by size and the relation between these two traits in Mediterranean oak species. The experiments consist of a set of field tests in which acorns from four different coexisting Mediterranean oak species ( Quercus ilex, Quercus faginea, Quercus suber, and Quercus coccifera) were placed in artificial feeders accessible to wild jays. The acorns were previously measured to control individual acorn characteristics. Using video-recording techniques, we followed jay activity and the fate of each acorn (sequence of acorn selection and method of transport). Q. ilex acorns were preferred over other acorns, and Q. coccifera acorns were avoided when other acorns were available. Preference for Q. faginea and Q. suber acorns was intermediate, that is, they were preferred over Q. coccifera acorns but not over Q. ilex acorns. Large acorns were also preferred although acorn species selection was stronger than size selection. Jays selected species and size both by visual means and by using acorn area as an indicator of size. Acorns wider than 17-19 mm were carried in the bill because of throat limitation. Our results confirm Bossema's study on temperate oaks and extend it to Mediterranean oak species, revealing implications on mixed oak forest dynamics.

Re-caching by Western scrub-jays (Aphelocoma californica) cannot be attributed to stress.  

PubMed

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. PMID:23326366

Western scrub-jays anticipate future needs independently of their current motivational state.  

PubMed

Planning for the future has been considered to be a uniquely human trait [1-3]. However, recent studies challenge this hypothesis by showing that food-caching Western scrub-jays (Aphelocoma californica) can relate their previous experience as thieves to the possibility of future cache theft by another bird [4], are sensitive to the state of their caches at recovery ([5] and S. De Kort, S.P.C.C., D. Alexis, A.D., and N.S.C., unpublished data), and can plan for tomorrow's breakfast [6]. Although these results suggest that scrub-jays are capable of future planning, the degree to which these birds act independently of their current motivational state is a matter of contention. The Bischof-Köhler hypothesis [1] holds that nonhuman animals cannot anticipate and act toward the satisfaction of a future need not currently experienced or cued by their present motivational state. Using specific satiety to control for the jays' current and future motivational states, here we specifically test this hypothesis by dissociating current and future motivational states. We report that Western scrub-jays anticipate the recovery of their caches, as well as their own future needs, by acting independently of their current motivational state and immediate needs. The fact that the birds act in favor of a future need as opposed to the current one challenges the hypothesis that this ability is unique to humans. PMID:17462894

Comparing alternative models to empirical data: cognitive models of western scrub-jay foraging behavior.

Animals often select one item from a set of candidates, as when choosing a foraging site or mate, and are expected to possess accurate and efficient rules for acquiring information and making decisions. Little is known, however, about the decision rules animals use. We compare patterns of information sampling by western scrub-jays (Aphelocoma californica) when choosing a nut with three decision rules: best of n (BN), flexible threshold (FT), and comparative Bayes (CB). First, we use a null hypothesis testing approach and find that the CB decision rule, in which individuals use past experiences to make nonrandom assessment and choice decisions, produces patterns of behavior that more closely correspond to observed patterns of nut sampling in scrub-jays than the other two rules. This approach does not allow us to quantify how much better CB is at predicting scrub-jay behavior than the other decision rules. Second, we use a model selection approach that uses Akaike Information Criteria to quantify how well alternative models approximate observed data. We find that the CB rule is much more likely to produce the observed patterns of scrub-jay behavior than the other rules. This result provides some of the best empirical evidence of the use of Bayesian information updating by a nonhuman animal. PMID:14970927

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. PMID:23326366

Food caching birds hide food and recover the caches when supplies are less abundant. There is, however, a risk to this strategy because the caches are susceptible to pilfering by others. Corvids use a number of different strategies to reduce possible cache theft. Scrub-jays with previous experience of pilfering other's caches cached worms in two visuospatially distinct caching trays either in private or in the presence of a conspecific. When these storers had cached in private, they subsequently observed both trays out of reach of a conspecific. When these storers had cached in the presence of a conspecific, they subsequently watched the observer pilfering from one of the trays while the other tray was placed in full view, but out of reach. The storers were then allowed to recover the remaining caches 3 h later. Jays cached more worms when they were observed during caching. At the time of recovery, they re-cached more than if they had cached in private, selectively re-caching outside of the trays in sites unbeknown to potential thieves. In addition, after a single pilfering trial, the jays switched their recovery strategy from predominantly checking their caches (i.e. returning to a cache site to see whether the food remained there) to predominantly eating them. Re-caching remained constant across the three trials. These results suggest that scrub-jays use flexible, cognitive caching and recovery strategies to aid in reducing potential future pilfering of caches by conspecifics. PMID:12827547

Visual coverage and scanning behavior in two corvid species: American crow and Western scrub jay.  

PubMed

Inter-specific differences in the configuration of avian visual fields and degree of eye/head movements have been associated with foraging and anti-predator behaviors. Our goal was to study visual fields, eye movements, and head movements in two species of corvids: American crow (Corvus brachyrhynchos) and Western scrub jay (Aphelocoma californica). American crows had wider binocular overlap, longer vertical binocular fields, narrower blind areas, and higher amplitude of eye movement than Western scrub jays. American crows can converge their eyes and see their own bill tip, which may facilitate using different foraging techniques (e.g., pecking, probing) and manufacturing and handing rudimentary tools. Western scrub jays had a higher head movement rate than American crows while on the ground, and the opposite between-species difference was found when individuals were perching. Faster head movements may enhance the ability to scan the environment, which may be related to a higher perceived risk of predation of Western scrub jays when on the ground, and American crows when perching. The visual field configuration of these species appears influenced mostly by foraging techniques while their scaning behavior, by predation risk. PMID:20803204

Interruptions improve choice performance in gray jays: prolonged information processing versus minimization of costly errors.  

PubMed

Under the assumption that selection favors minimization of costly errors, erroneous choice may be common when its fitness cost is low. According to an adaptive-choice model, this cost depends on the rate at which an animal encounters the choice: the higher this rate, the smaller the cost of choosing a less valuable option. Errors should thus be more common when interruptions to foraging are shorter. A previous experiment supported this prediction: gray jays, Perisoreus canadensis, were more error prone when subjected to shorter delays to access to food rewards. This pattern, though, is also predicted by an attentional-constraints model. Because the subjects were able to inspect the rewards during delays, their improved performance when subjected to longer delays could have been a byproduct of the experimentally prolonged opportunity for information processing. To evaluate this possibility, a follow-up experiment manipulated both delay to access and whether rewards could be inspected during delays. Depriving jays of the opportunity to inspect rewards (using opaque lids) induced only a small, nonsignificant increase in error rate. This effect was independent of length of delay and so the jays' improved performance when subjected to longer delays was not simply a byproduct of prolonged information processing. More definitively, even when the jays were prevented from inspecting rewards during delays, their performance improved when subjected to longer delays. The findings are thus consistent with the adaptive-choice model. PMID:12461598

The JCMT Legacy Survey of the Gould Belt: a first look at Serpens with HARP  

NASA Astrophysics Data System (ADS)

The Gould Belt Legacy Survey on the James Clerk Maxwell Telescope's has observed a region of 260 arcmin2 in 12CO J= 3 ? 2 emission, and a 190 arcmin2 subset of this in 13CO and C18O towards the Serpens molecular cloud. We examine the global velocity structure of the non-outflowing gas, and calculate excitation temperatures and opacities. The large-scale mass and energetics of the region are evaluated, with special consideration for high-velocity gas. We find the cloud to have a mass of 203 M?, and to be gravitationally bound, and that the kinetic energy of the outflowing gas is approximately 70 per cent of the turbulent kinetic energy of the cloud. We identify compact outflows towards some of the submillimetre Class 0/I sources in the region.

The JCMT Gould Belt Survey: SCUBA-2 observations of radiative feedback in NGC 1333  

NASA Astrophysics Data System (ADS)

We present observations of NGC 1333 from SCUBA-2 on the James Clerk Maxwell Telescope (JCMT), observed as a JCMT Gould Belt Survey pilot project during the shared risk campaign when the first of four arrays was installed at each of 450 and 850 ?m. Temperature maps are derived from 450 and 850 ?m ratios under the assumption of constant dust opacity spectral index ? = 1.8. Temperatures indicate that the dust in the northern (IRAS 6/8) region of NGC 1333 is hot, 20-40 K, due to heating by the B star SVS3, other young stars in the IR/optically visible cluster and embedded protostars. Other luminous protostars are also identified by temperature rises at the 17 arcsec resolution of the ratio maps (0.02 pc assuming a distance of 250 pc for Perseus). The extensive heating raises the possibility that the radiative feedback may lead to increased masses for the next generation of stars.

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.

Rapid divergence and postglacial colonization in western North American Steller's jays (Cyanocitta stelleri).  

PubMed

Post-Pleistocene avian colonization of deglaciated North America occurred from multiple refugia, including a coastal refugium in the northwest. The location of a Pacific Coastal refugium is controversial; however, multiple lines of evidence suggest that it was located near the Queen Charlotte Islands (also known as Haida Gwaii). The Queen Charlotte Islands contain a disproportionately large number of endemic plants and animals including the Steller's jay Cyanocitta stelleri carlottae. Using five highly variable microsatellite markers, we studied population structure among eight populations of Steller's jay (N = 150) from geographical areas representing three subspecies in western North America: C. s. carlottae, C. s. stelleri and C. s. annectens. Microsatellite analyses revealed genetic differentiation between each of the three subspecies, although more extensive sampling of additional C. s. annectens populations is needed to clarify the level of subspecies differentiation. High levels of population structure were found among C. s. stelleri populations with significant differences in all but two pairwise comparisons. A significant isolation by distance pattern was observed amongst populations in the Pacific Northwest and Alaska. In the C. s. carlottae population, there was evidence of reduced genetic variation, higher number of private alleles than northern C. s. stelleri populations and higher levels of divergence between Queen Charlotte Island and other populations. We were unable to reject the hypothesis that the Queen Charlotte Islands served as a refugium during the Pleistocene. Steller's jay may have colonized the Queen Charlotte Islands near the end of the last glaciation or persisted throughout the Pleistocene, and this subspecies may thus represent a glacial relic. The larger number of private alleles, despite reduced genetic variation, morphological distinctiveness and high divergence from other populations suggests that the Queen Charlotte Island colonization pre-dates that of the mainland. Furthermore, our results show rapid divergence in Steller's jay populations on the mainland following the retreat of the ice sheets. PMID:16202093

Based on masers with measured trigonometric parallaxes, we have redetermined the spatial orientation parameters of the Local (Orion) arm. Using 23 sources (the Gould Belt objects were excluded), we have found that their spatial distribution can be approximated by a very narrow ellipsoid elongated in the direction L_1=77.1+/-2.9^o whose symmetry plane is inclined to the Galactic plane at an angle of 5.6+/-0.2^o. The longitude of the ascending node of the symmetry plane is l_\\Omega=70+/-3^o. A new estimate for the pitch angle of the Local spiral arm has been obtained by an independent method: i=12.9+/-2.9^o. Previously, a belt of young B stars, the de Vaucouleurs.Dolidze belt, was pointed out on the celestial sphere with parameters close to such an orientation. We have refined the spatial orientation parameters of this belt based on a homogeneous sample of protostars. The de Vaucouleurs.Dolidze belt can be identified with the Local arm, with the belt proper as a continuous band on the celestial sphere like the ...

A Markov decision process for managing habitat for Florida scrub-jays  

USGS Publications Warehouse

Florida scrub-jays Aphelocoma coerulescens are listed as threatened under the Endangered Species Act due to loss and degradation of scrub habitat. This study concerned the development of an optimal strategy for the restoration and management of scrub habitat at Merritt Island National Wildlife Refuge, which contains one of the few remaining large populations of scrub-jays in Florida. There are documented differences in the reproductive and survival rates of scrubjays among discrete classes of scrub height (<120 cm or "short"; 120-170 cm or "optimal"; .170 cm or "tall"; and a combination of tall and optimal or "mixed"), and our objective was to calculate a state-dependent management strategy that would maximize the long-term growth rate of the resident scrub-jay population. We used aerial imagery with multistate Markov models to estimate annual transition probabilities among the four scrub-height classes under three possible management actions: scrub restoration (mechanical cutting followed by burning), a prescribed burn, or no intervention. A strategy prescribing the optimal management action for management units exhibiting different proportions of scrub-height classes was derived using dynamic programming. Scrub restoration was the optimal management action only in units dominated by mixed and tall scrub, and burning tended to be the optimal action for intermediate levels of short scrub. The optimal action was to do nothing when the amount of short scrub was greater than 30%, because short scrub mostly transitions to optimal height scrub (i.e., that state with the highest demographic success of scrub-jays) in the absence of intervention. Monte Carlo simulation of the optimal policy suggested that some form of management would be required every year. We note, however, that estimates of scrub-height transition probabilities were subject to several sources of uncertainty, and so we explored the management implications of alternative sets of transition probabilities. Generally, our analysis demonstrated the difficulty of managing for a species that requires midsuccessional habitat, and suggests that innovative management tools may be needed to help ensure the persistence of scrub-jays at Merritt Island National Wildlife Refuge. The development of a tailored monitoring program as a component of adaptive management could help reduce uncertainty about controlled and uncontrolled variation in transition probabilities of scrub-height and thus lead to improved decision making.

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. PMID:23970442

The JCMT Legacy Survey of the Gould Belt: a first look at Taurus with HARP  

NASA Astrophysics Data System (ADS)

As part of a James Clerk Maxwell Telescope (JCMT) Legacy Survey of star formation in the Gould Belt, we present early science results for Taurus. CO J = 3 -2 maps have been secured along the north-west ridge and bowl, collectively known as L 1495, along with deep 13CO and C18O J = 3 -2 maps in two subregions. With these data, we search for molecular outflows, and use the distribution of flows, Herbig-Haro (HH) objects and shocked H2 line-emission features, together with the population of young stars, protostellar cores and starless condensations to map star formation across this extensive region. In total, 21 outflows are identified. It is clear that the bowl is more evolved than the ridge, harbouring a greater population of T Tauri stars and a more diffuse, more turbulent ambient medium. By comparison, the ridge contains a much younger, less widely distributed population of protostars which, in turn, is associated with a greater number of molecular outflows. We estimate the ratio of the numbers of pre-stellar to protostellar cores in L 1495 to be ~1.3-2.3, and of gravitationally unbound starless cores to (gravitationally bound) pre-stellar cores to be ~1. If we take previous estimates of the protostellar lifetime of ~5 × 105 yr, this indicates a pre-stellar lifetime of 9(+/-3) × 105 yr. From the number of outflows, we also crudely estimate the star formation efficiency in L 1495, finding it to be compatible with a canonical value of 10-15 per cent. We note that molecular outflow-driving sources have redder near-infrared colours than their HH jet-driving counterparts. We also find that the smaller, denser cores are associated with the more massive outflows, as one might expect if mass build-up in the flow increases with the collapse and contraction of the protostellar envelope.

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.

Temporal predictability in food availability: effects upon the reproductive axis in Scrub-Jays.  

PubMed

Florida Scrub-Jays (Aphelocoma coerulescens) in a suburban environment with year-round access to multiple sources of abundant, human-source foods consistently breed earlier each year and have lower baseline levels of circulating corticosterone (CORT) than jays in a nearby wildland setting. These findings suggest that food supplies influence CORT levels, which in turn may partially determine the timing of reproduction. However, wildland birds with access to high-quality supplemental foods did not advance breeding or lower CORT levels to the degree observed in the suburbs. Therefore, rather than quality or quantity of food consumed, the perception of a reliable and predictable food supply may be an important factor in determining laying dates. If a predictable food supply accelerates the reproductive process, it follows that food provided on an unpredictable schedule may slow reproduction. We subjected captive Western Scrub-Jays (A. californica) to a 30-day photoperiod transition from short- to long-days and tested whether birds with access to food on an unpredictable schedule exhibited delayed or reduced production of reproductive hormones compared with birds given food on a predictable schedule. Baseline CORT concentrations increased slightly during the experiment, but did not differ between treatment groups. Birds with unpredictable food had slightly lower testosterone levels relative to controls, but there was no effect on estradiol or luteinizing hormone. Our findings offer weak support for the hypothesis that an unpredictable food supply will delay the onset of reproduction; however, the artificial lab environment may limit the application of these findings to free-living populations.

Experimental West Nile virus infection in blue jays (Cyanocitta cristata) and crows (Corvus brachyrhynchos).  

PubMed

Ten crows (Corvus brachyrhynchos) and three blue jays (Cyanocitta cristata), species indigenous to North America, were intravenously inoculated with 10(3) PFU of West Nile virus (WNV) strain NY99 for production of positive tissues for Canadian surveillance. Both species developed clinical signs 4 days postinoculation (dpi). Virus was detected in blood, cloacal and tracheal swabs, and in a number of organs by reverse transcriptase-polymerase chain reaction (RT-PCR) and virus isolation (titers reaching over 10(7) PFU/0.1 g). Virus appeared as early as 1 dpi in blood (10(2)-10(3) PFU/ml) and spleen (10(3)-10(4) PFU/0.1 g of tissue), whereas kidney, liver, intestine, gonads, heart, skeletal muscle, and lung tested positive for WNV in a later stage of the infection. Immunostaining (IHC) using heterologous rabbit anti-WNV polyclonal antiserum detected viral antigen in a wide range of organs, starting at 2 dpi. Detection of WNV antigen in the brain of blue jays and crows by IHC was laborious as only few cells, not present in all sections, would stain positive. Mononuclear cells appeared to be an important target for virus replication, contributing to virus spread throughout tissues during the infection. This conclusion was based on the positive IHC staining of these cells in organs before virus antigen detection in parenchymal cells and supported by virus isolation and RT-PCR-positive results in white blood cells. The inability of blue jays and crows to perch and fly may reflect weakness due to generalized infection and marked skeletal muscle involvement, although involvement of the central nervous system cannot be excluded.

Sociality and social learning in two species of corvids: the pinyon jay (Gymnorhinus cyanocephalus) and the Clark's nutcracker (Nucifraga columbiana).  

PubMed

The hypothesis that social learning is an adaptive specialization for social living predicts that social species should learn better socially than they do individually, but that nonsocial species should not exhibit a similar enhancement of performance under social learning conditions. The authors compared individual and social learning abilities in 2 corvid species: the highly social pinyon jay (Gymnorhinus cyanocephalus) and the less social Clark's nutcracker (Nucifraga columbiana). The birds were tested on 2 different tasks under individual and social learning conditions. Half learned a motor task individually and a discrimination task socially; the other half learned the motor task socially and the discrimination task individually. Pinyon jays learned faster socially than they did individually, but nutcrackers performed equally well under both learning conditions. Results support the hypothesis that social learning is an adaptive specialization for social living in pinyon jays. PMID:10608569

Age-related differences in baseline and stress-induced corticosterone in Florida scrub-jays.  

PubMed

In physiological studies of free-living species, it is essential to consider the context of the life history stage at which an individual was observed in order to link measures of physiology with ecological parameters. One such measure that is important to consider is the age of an individual. We tested whether baseline or stress-induced corticosterone levels vary with age in free-living Florida scrub-jays (Aphelocoma coerulescens) during the pre-breeding period. Corticosterone (CORT), the primary avian stress hormone, is released in response to stressful stimuli, and stimulates gluconeogenesis; however, it also serves as a chemical messenger that can influence other physiological processes, reproduction, and behavior. We monitored both baseline CORT levels longitudinally throughout a five-year period and stress-induced CORT responses over a shorter two-year period. We predicted that older jays would have lower baseline CORT levels and a dampened stress response compared to younger birds, as has been shown in other avian species. We found no significant differences in baseline CORT levels with age. We found a decrease in total corticosterone responses to a stressor with age, however, the oldest birds in the population showed greater total corticosterone responses to a stressor. These results may be a product of age-related changes in physiological processes related to the stress response or a result of selection acting on the population, resulting in only the most responsive individuals surviving to old age.

Ixodes dammini (Acari: Ixodidae) infestation on medium-sized mammals and blue jays in northwestern Illinois.  

PubMed

High prevalence of infestation of five species of medium-sized mammals and blue jays, Cyanocitta cristata (L.), by immature Ixodes dammini Spielman, Clifford, Piesman and Corwin was found in Castle Rock State Park in northwestern Illinois during May-August 1991. Raccoons, Procyon lotor L., and opossums, Didelphis virginiana Kerr, were infested with the highest larval densities and were trapped primarily in bottomland forest and ecotone habitats. All species had similar nymphal densities, except the eastern cottontails, Sylvilagus floridanus Allen, which were infested with fewer nymphs. Infestation by I. dammini is reported for the first time for fox squirrels, Sciurus niger E. G. St. Hilaire, and for the first time in the midwestern United States for blue jays, C. cristata. These two species were hosts for nymphs in upland forest habitat. Molting rates varied among ticks that fed on different host species and among larvae that fed on individuals of the same species. Molting rate is proposed as an important factor in determining the relative importance of a host species to I. dammini population dynamics. PMID:8254647

Hierarchical star formation: stars and stellar clusters in the Gould Belt  

NASA Astrophysics Data System (ADS)

We perform a study of the spatial and kinematical distribution of young open clusters in the solar neighbourhood, discerning between bound clusters and transient stellar condensations within our sample. Then, we discriminate between Gould Belt (GB) and local Galactic disc (LGD) members, using our previous estimate of the structural parameters of both systems obtained from a sample of O-B6 Hipparcos stars. Single membership probabilities of the clusters are also calculated in the separation process. Using this classified sample, we analyse the spatial structure and the kinematic behaviour of the cluster system in the GB. The two star formation regions that dominate and give the GB its characteristic-inclined shape show a striking difference in their content of star clusters: while Ori OB1 is richly populated by open clusters, not a single one can be found within the boundaries of Sco OB2. This is mirrored in the velocity space, translating again into an abundance of clusters in the region of the kinematic space populated by the members of Ori OB1, and a marginal number of them associated with Sco OB2. We interpret all these differences by characterizing the Orion region as a cluster complex typically surrounded by a stellar halo, and the Sco-Cen region as an OB association in the outskirts of the complex. In the light of these results, we study the nature of the GB with respect to the optical segment of the Orion Arm, and we propose that the different content of star clusters, the different heights over the Galactic plane and the different residual velocities of Ori OB1 and Sco OB2 can be explained in terms of their relative position to the density maximum of the Local Arm in the solar neighbourhood. Although morphologically intriguing, the GB appears to be the result of our local and biased view of a larger star cluster complex in the Local Arm, that could be explained by the internal dynamics of the Galactic disc.

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

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.

Psychopathic characters on the stage of Stephen Sondheim.  

PubMed

Many of the characters in Stephen Sondheim's musical theater are burdened with a character pathology which results in their inability to establish intimate relationships. Drawing on Freud's "Psychopathic characters on the stage" and psychoanalytic theory, this article suggests that developmental, biological, and environmental factors from Sondheim's childhood contribute to his characters' social and interpersonal alienation. Sondheim's art is a partially successful attempt to re-assert connections and repair narcissistic injuries, introjecting the absent mother as part of the superego. The resistance to dramatizing character pathology through biography is both an expression of society's postmodern fragmentation and resistance to Oedipal drama. PMID:17370466

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.

Is the western scrub-jay (Aphelocoma californica) really an underdog among food-caching corvids when it comes to hippocampal volume and food caching propensity?  

PubMed

Food caching has been linked to better performance on spatial memory tasks and enlarged hippocampal volume in both birds and mammals. Within food-caching birds, it has also been predicted that species less reliant on stored food should have inferior spatial memory and a smaller hippocampus compared to species that depend heavily on food caches. Several comparisons suggest that North American corvids have a significantly smaller hippocampus and overall brain volume compared to the Eurasian corvid species and that western scrub-jays (Aphelocoma californica) have a smaller hippocampus compared to the more specialized Clark's nutcracker. Here we present the largest data set of scrub-jay brains and, in contrast to previous reports, show that relative to body mass western scrub-jays have a brain size similar to the largest brain size of Eurasian corvids. The relative hippocampal volume of scrub-jays is also among the largest of all investigated corvids. These findings may not be surprising considering that scrub-jays have been reported to have remarkable cognitive capacities such as episodic-like memory and experience projection. Our data suggest that many previously made assumptions about western scrub-jays as less specialized food hoarders might be an oversimplification and that simple categorization of species into specialized and non-specialized hoarders might not provide useful insights into the evolution of memory and the hippocampus.

Can male Eurasian jays disengage from their own current desire to feed the female what she wants?  

PubMed

Humans' predictions of another person's behaviour are regularly influenced by what they themselves might know or want. In a previous study, we found that male Eurasian jays (Garrulus glandarius) could cater for their female partner's current desire when sharing food with her. Here, we tested the extent to which the males' decisions are influenced by their own current desire. When the males' and female's desires matched, males correctly shared the food that was desired by both. When the female's desire differed from their own, the males' decisions were not entirely driven by their own desires, suggesting that males also took the female's desire into account. Thus, the male jays' decisions about their mates' desires are partially biased by their own desire and might be based upon similar processes as those found in humans. PMID:24671829

[Stephens-Fowler in two times: results 14 years later].  

PubMed

The management of intra-abdominal testis can be challenging, as evidenced by the multiple methods suggested for its assessment and treatment. In this paper, we report our long-term results for our 14-year surgical experience with laparoscopic management. Methods. Retrospective study of laparoscopic interventions performed at our department for nonpalpable testes between 1996 and 2009. In 174 procedures, we found 72 intra-abdominal testes (5 bilateral) and 25 direct orchiopexies (3 bilateral) were performed. One-stage Fowler-Stephens orchiopexies (FSO) were performed in 5 children. 40 boys underwent the two-stage FSO technique (2 bilateral) in those that reached the contralateral inguinal ring. The second stage was performed in 4 cases with a laparoscopic approach, the rest of them underwent an inguinal procedure exclusively. Mean age for the first intervention was 3.7 yrs, and the second stage was performed on average after 10.9 months. Of 42 undescended testes, 22 were on the right side and 20 on the left side. Median followup was 24 months. Results. Of 42 two-stage FSOs performed, 27 surgeries were very successful, with a testis size equivalent to the contralateral mate; 7 had good results, with a smaller testis (volume up to 50% of contralateral); and 7 resulted in atrophic testis. No complications were encountered during surgery. Conclusions. There is no doubt about the usefulness of laparoscopy for intra-abdominal testes with short spermatic vessels, and the two-stage Fowler-Stephens technique should be the procedure of choice given its high success rate.

Uncertainty-based grade modelling of kimberlite: A case study of the Jay kimberlite pipe, EKATI Diamond Mine, Canada  

NASA Astrophysics Data System (ADS)

Understanding uncertainty in resource models is a significant requirement of mineral resource evaluation. Geostatistical simulation is one method that can be used to quantify uncertainty and Sequential Gaussian Simulation (SGS) is one of the easiest techniques to understand and implement. Using SGS provides both a spatial model of a given variable and the ranges around that variable at any number of scales. The Jay kimberlite pipe is located in the southeastern quadrant of the EKATI property. Drilling to date has identified three kimberlitic domains characterized by varying lithological properties. These domains are not separated by hard contacts, but rather by boundaries that are transitional. Within these domains, vertical trends exist; in particular, diamond grade increases with depth. For these reasons, Jay required an in-depth investigation of the best uncertainty-based grade modelling method to use. Grade was modelled by organic SGS and by using the stepwise conditional transform (SCT) to incorporate a trend into the simulation routine. Although the SGS results were valid, they did not fully reproduce the trend and therefore, the results did not fully match the geological interpretation of the deposit. The SCT results reproduced the trend, however, did not correspond to the variability of the data and therefore under-represented the actual uncertainty in the model. This was confirmed through detailed uncertainty calculation and probabilistic resource classification. Therefore, the SGS model was chosen as the preferred uncertainty-based grade model for the Jay pipe.

Development of the adrenal stress response in the Florida scrub-jay (Aphelocoma coerulescens).  

PubMed

Nestlings of altricial species undergo a period of substantial growth and development in the nest after hatching. The hypothalamic-pituitary-adrenal axis regulates the release of stress hormones such as corticosterone, which in adults is critical in allowing an animal to respond to a stressor. However, activation of this axis in young birds may be detrimental to growth and possibly survival. The developmental hypothesis predicts that altricial nestlings should display a dampened corticosterone response to stress as a means of protection against the potentially harmful effects of elevated corticosterone. We examined this hypothesis in Florida scrub-jays, a cooperatively breeding species with altricial young. Blood samples were collected from nestlings, nutritionally independent young, and yearlings for measurement of corticosterone levels. Baseline corticosterone levels did not differ between age-classes; however, stress-induced corticosterone levels were highest in yearlings, intermediate in independent young, and lowest in nestlings. The nestling stress response was also of a shorter duration than the response in independent young and yearlings. This variation in stress responsiveness across ages may be an adaptive mechanism to protect the developing bird from the negative effects of corticosterone on growth and cognitive development.

Geographic variation in the community structure of lice on western scrub-jays.  

PubMed

Parasites are incredibly diverse. An important factor in the evolution of this diversity is the fact that many parasite species are restricted to 1, or just a few, host species. In addition, some parasites exhibit geographic specificity that is nested within their specificity to a particular species of host. The environmental factors that restrict parasites to particular regions within the host's range are poorly understood, and it is often difficult to know whether such patterns of geographic specificity are real, or merely artifacts of uneven host sampling. For over a decade, we sampled communities of ectoparasitic lice (Phthiraptera) from western scrub-jays (Aphelocoma californica) throughout their range in the United States, and found 3 common species of lice. Philopterus crassipes was found throughout the host range, whereas the other 2 species of lice had more restricted distributions. Brueelia deficiens was found only on the woodhouseii host subspecies group, and Myrsidea sp. was found largely on the californica host subspecies group. We suggest that differential tolerance to arid conditions and interspecific competition has led to the restricted geographic distributions of these 2 species of lice. PMID:18576864

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. PMID:23382187

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. PMID:23293376

The JCMT Legacy Survey of the Gould Belt: mapping 13CO and C18O in Orion A  

E-print Network

The Gould Belt Legacy Survey will map star-forming regions within 500 pc, using HARP (Heterodyne Array Receiver Programme), SCUBA-2 (Submillimetre Common-User Bolometer Array 2) and POL-2 (Polarimeter 2) on the James Clerk Maxwell Telescope (JCMT). This paper describes HARP observations of the J = 3-2 transitions of 13CO and C18O towards Orion A. The 1500-resolution observations cover 5 pc of the Orion filament, including OMC1 (inc. BN-KL and Orion Bar), OMC 2/3 and OMC 4, and allow a comparative study of the molecular gas properties throughout the star-forming cloud. The filament shows a velocity gradient of ~1 km/s /pc between OMC 1, 2 and 3, and high velocity emission is detected in both isotopologues. The Orion Nebula and Bar have the largest masses and line widths, and dominate the mass and energetics of the high velocity material. Compact, spatially resolved emission from CH3CN, 13CH3OH, SO, HCOOCH3, C2H5OH, CH3CHO and CH3OCHO is detected towards the Orion Hot Core. The cloud is warm, with a median exci...

The James Clerk Maxwell Telescope Legacy Survey of Nearby Star-forming Regions in the Gould Belt  

NASA Astrophysics Data System (ADS)

This paper describes a James Clerk Maxwell Telescope (JCMT) legacy survey that has been awarded roughly 500 hr of observing time to be carried out from 2007 to 2009. In this survey, we will map with SCUBA-2 (Submillimetre Common-User Bolometer Array 2) almost all of the well-known low-mass and intermediate-mass star-forming regions within 0.5 kpc that are accessible from the JCMT. Most of these locations are associated with the Gould Belt. From these observations, we will produce a flux-limited snapshot of star formation near the Sun, providing a legacy of images, as well as point-source and extended-source catalogs, over almost 700 deg2 of sky. The resulting images will yield the first catalog of prestellar and protostellar sources selected by submillimeter continuum emission, and should increase the number of known sources by more than an order of magnitude. We will also obtain with the array receiver HARP (Heterodyne Array Receiver Program) CO maps, in three CO isotopologues, of a large typical sample of prestellar and protostellar sources. We will then map the brightest hundred sources with the SCUBA-2 polarimeter (POL-2), producing the first statistically significant set of polarization maps in the submillimeter. The images and source catalogs will be a powerful reference set for astronomers, providing a detailed legacy archive for future telescopes, including ALMA, Herschel, and JWST.

Road load simulator tests of the Gould phase 1 functional model silicon controlled rectifier ac motor controller for electric vehicles  

NASA Technical Reports Server (NTRS)

The test results for a functional model ac motor controller for electric vehicles and a three-phase induction motor which were dynamically tested on the Lewis Research Center road load simulator are presented. Results show that the controller has the capability to meet the SAE-J227a D cycle test schedule and to accelerate a 1576-kg (3456-lb) simulated vehicle to a cruise speed of 88.5 km/hr (55 mph). Combined motor controller efficiency is 72 percent and the power inverter efficiency alone is 89 percent for the cruise region of the D cycle. Steady state test results for motoring, regeneration, and thermal data obtained by operating the simulator as a conventional dynamometer are in agreement with the contractor's previously reported data. The regeneration test results indicate that a reduction in energy requirements for urban driving cycles is attainable with regenerative braking. Test results and data in this report serve as a data base for further development of ac motor controllers and propulsion systems for electric vehicles. The controller uses state-of-the-art silicon controlled rectifier (SCR) power semiconductors and microprocessor-based logic and control circuitry. The controller was developed by Gould Laboratories under a Lewis contract for the Department of Energy's Electric and Hybrid Vehicle program.

Young stellar kinematic groups and their relation with young open clusters, star forming regions and the Gould Belt  

E-print Network

Stellar kinematic groups (SKG) are kinematically coherent groups of stars that share a common origin. We have compiled (Montes et al. 1999; 2000) a sample of late-type stars of previously established members and possible new candidates to different young SKG (Local Association (20 - 150 Myr), Ursa Mayor group (300 Myr), Hyades supercluster (600 Myr), IC 2391 supercluster (35 Myr) and Castor Moving Group (200 Myr)). In order to better understand the origin of these young SKG, and to be able to identify late-type stars members of the classical and the recently identified SKG, we also need to study the kinematic properties of nearby young open clusters and star forming regions. With this aim we have taken the most recent data available in the literature (including astrometric data from Hipparcos Catalogue) of the nearby young open clusters, OB associations, T associations, and other associations of young stars as TW Hya. We use these data to calculate their Galactic space motions (U, V, W) and space coordinates (X, Y, Z) and study their possible association with the different SKG as well as with the young flattened and inclined Galactic structure known as the Gould Belt.

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

NASA Astrophysics Data System (ADS)

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, which Herschel rejected. 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.

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

Effects of fouling on the Japanese scallop Mizuhopecten yessoensis (Jay) in Peter the Great Bay (Sea of Japan)  

NASA Astrophysics Data System (ADS)

A valuable mariculture object, the Japanese scallop Mizuhopecten (= Patinopevten) yessoensis (Jay), after six hours long transportation by air and sowing on the bottom is fouled greater by epi- and endolythical organisms than the members of the native population. It is likely that the fouling negatively affects the specimens, those that were the largest before the sowing at the bottom were not found among those that reached puberty. The results of the effects of the endolythic polychaete Polydora brevipalpa and the barnacle Hesperibalanus hesperius on the growth rate of the Japanese scallop cultivated on the bottom of Peter the Great Bay (Sea of Japan) are provided in this paper.

High latitudes and high genetic diversity: phylogeography of a widespread boreal bird, the gray jay (Perisoreus canadensis).  

PubMed

We describe range-wide phylogeographic variation in gray jays (Perisoreus canadensis), a boreal Nearctic corvid that occurs today primarily in recently glaciated regions. Phylogenetic analysis of mitochondrial DNA (1041 base pairs ND2 gene; N=205, 50 localities) revealed four reciprocally monophyletic groups. One widespread clade occurs across the North American boreal zone, from Newfoundland to Alaska and southwest into Utah. Three other clades occur at lower latitudes in the montane West in Colorado, the northern Rocky Mountains, and the Pacific Northwest respectively. The geographic distribution of clades in gray jays corresponds with a general pattern that is emerging for boreal taxa, having one widespread northern clade and one or more geographically restricted southwestern clades. Population genetic analyses indicate that the larger boreal clade is genetically structured and harbors significantly more genetic diversity than those clades occurring at lower latitudes. Species distribution modeling (SDM) revealed multiple putative Pleistocene refugia including several occurring at higher latitudes. We suggest that multiple post-glacial colonization routes, some of which originate from these northern refugia, are responsible for the relatively high genetic diversity at high latitudes. Conversely, lower latitude clades show little variation, probably as a result of historical restriction to smaller geographical areas with smaller long-term population sizes. This 'upside-down' pattern of genetic diversity contrasts with the conventional view that populations of north-temperate species occupying previously glaciated habitats should possess lower levels of diversity than their southern counterparts.

Speciation in Western Scrub-Jays, Haldane's rule, and genetic clines in secondary contact  

PubMed Central

Background Haldane’s Rule, the tendency for the heterogametic sex to show reduced fertility in hybrid crosses, can obscure the signal of gene flow in mtDNA between species where females are heterogametic. Therefore, it is important when studying speciation and species limits in female-heterogametic species like birds to assess the signature of gene flow in the nuclear genome as well. We studied introgression of microsatellites and mtDNA across a secondary contact zone between coastal and interior lineages of Western Scrub-Jays (Aphelocoma californica) to test for a signature of Haldane’s Rule: a narrower cline of introgression in mtDNA compared to nuclear markers. Results Our initial phylogeographic analysis revealed that there is only one major area of contact between coastal and interior lineages and identified five genetic clusters with strong spatial structuring: Pacific Slope, Interior US, Edwards Plateau (Texas), Northern Mexico, and Southern Mexico. Consistent with predictions from Haldane’s Rule, mtDNA showed a narrower cline than nuclear markers across a transect through the hybrid zone. This result is not being driven by female-biased dispersal because neutral diffusion analysis, which included estimates of sex-specific dispersal rates, also showed less diffusion of mtDNA. Lineage-specific plumage traits were associated with nuclear genetic profiles for individuals in the hybrid zone, indicating that these differences are under genetic control. Conclusions This study adds to a growing list of studies that support predictions of Haldane’s Rule using cline analysis of multiple loci of differing inheritance modes, although alternate hypotheses like selection on different mtDNA types cannot be ruled out. That Haldane’s Rule appears to be operating in this system suggests a measure of reproductive isolation between the Pacific Slope and interior lineages. Based on a variety of evidence from the phenotype, ecology, and genetics, we recommend elevating three lineages to species level: A. californica (Pacific Slope); A. woodhouseii (Interior US plus Edwards Plateau plus Northern Mexico); A. sumichrasti (Southern Mexico). The distinctive Edwards Plateau population in Texas, which was monophyletic in mtDNA except for one individual, should be studied in greater detail given habitat threat. PMID:24938753

The Spitzer Survey of Interstellar Clouds in the Gould Belt. VI. The Auriga-California Molecular Cloud observed with IRAC and MIPS  

E-print Network

We present observations of the Auriga-California Molecular Cloud (AMC) at 3.6, 4.5, 5.8, 8.0, 24, 70 and 160 micron observed with the IRAC and MIPS detectors as part of the Spitzer Gould Belt Legacy Survey. The total mapped areas are 2.5 sq-deg with IRAC and 10.47 sq-deg with MIPS. This giant molecular cloud is one of two in the nearby Gould Belt of star-forming regions, the other being the Orion A Molecular Cloud (OMC). We compare source counts, colors and magnitudes in our observed region to a subset of the SWIRE data that was processed through our pipeline. Using color-magnitude and color-color diagrams, we find evidence for a substantial population of 166 young stellar objects (YSOs) in the cloud, many of which were previously unknown. Most of this population is concentrated around the LkHalpha 101 cluster and the filament extending from it. We present a quantitative description of the degree of clustering and discuss the fraction of YSOs in the region with disks relative to an estimate of the diskless YS...

THE HERSCHEL AND JCMT GOULD BELT SURVEYS: CONSTRAINING DUST PROPERTIES IN THE PERSEUS B1 CLUMP WITH PACS, SPIRE, AND SCUBA-2  

SciTech Connect

We present Herschel observations from the Herschel Gould Belt Survey and SCUBA-2 science verification observations from the JCMT Gould Belt Survey of the B1 clump in the Perseus molecular cloud. We determined the dust emissivity index using four different techniques to combine the Herschel PACS+SPIRE data at 160-500 {mu}m with the SCUBA-2 data at 450 {mu}m and 850 {mu}m. Of our four techniques, we found that the most robust method was filtering out the large-scale emission in the Herschel bands to match the spatial scales recovered by the SCUBA-2 reduction pipeline. Using this method, we find {beta} Almost-Equal-To 2 toward the filament region and moderately dense material and lower {beta} values ({beta} {approx}> 1.6) toward the dense protostellar cores, possibly due to dust grain growth. We find that {beta} and temperature are more robust with the inclusion of the SCUBA-2 data, improving estimates from Herschel data alone by factors of {approx}2 for {beta} and by {approx}40% for temperature. Furthermore, we find core mass differences of {approx}< 30% compared to Herschel-only estimates with an adopted {beta} = 2, highlighting the necessity of long-wavelength submillimeter data for deriving accurate masses of prestellar and protostellar cores.

A Conservation Strategy for the Florida Scrub-Jay on John F. Kennedy Space Center/Merritt Island National Wildlife Refuge: An Initial Scientific Basis for Recovery  

NASA Technical Reports Server (NTRS)

The Florida Scrub-Jay (Aphelocoma coerulescens) is an indicator of ecosystem integrity of Florida scrub, an endangered ecosystem that requires frequent fire. One of the largest populations of this federally threatened species occurs on John F. Kennedy Space Center/Merritt Island National Wildlife Refuge. Population trends were predicted using population modeling and field data on reproduction and survival of Florida Scrub-Jays collected from 1988 - 1995. Analyses of historical photography indicated that habitat suitability has been declining for 30 years. Field data and computer simulations suggested that the population declined by at least 40% and will decline by another 40% in 1 0 years, if habitat management is not greatly intensified. Data and computer simulations suggest that habitat suitability cannot deviate greatly from optimal for the jay population to persist. Landscape trajectories of vegetation structure, responsible for declining habitat suitability, are associated with the disruption of natural fire regimes. Prescribed fire alone can not reverse the trajectories. A recovery strategy was developed, based on studies of Florida Scrub-Jays and scrub vegetation. A reserve design was formulated based on conservation science principles for scrub ecosystems. The strategy emphasizes frequent fire to restore habitat, but includes mechanical tree cutting for severely degraded areas. Pine thinning across large areas can produce rapid increases in habitat quality. Site-specific strategies will need to be developed, monitored, and modified to achieve conditions suitable for population persistence.

The JCMT Legacy Survey of the Gould Belt: mapping 13CO and C18O in Orion A  

NASA Astrophysics Data System (ADS)

The Gould Belt Legacy Survey will map star-forming regions within 500 pc, using Heterodyne Array Receiver Programme (HARP), Submillimetre Common-User Bolometer Array 2 (SCUBA-2) and Polarimeter 2 (POL-2) on the James Clerk Maxwell Telescope (JCMT). This paper describes HARP observations of the J= 3 ? 2 transitions of 13CO and C18O towards Orion A. The 15 arcsec resolution observations cover 5 pc of the Orion filament, including OMC 1 (including BN-KL and Orion bar), OMC 2/3 and OMC 4, and allow a comparative study of the molecular gas properties throughout the star-forming cloud. The filament shows a velocity gradient of ˜1 km s-1 pc-1 between OMC 1, 2 and 3, and high-velocity emission is detected in both isotopologues. The Orion Nebula and Bar have the largest masses and linewidths, and dominate the mass and energetics of the high-velocity material. Compact, spatially resolved emission from CH3CN, 13CH3OH, SO, HCOOCH3, CH3CHO and CH3OCHO is detected towards the Orion Hot Core. The cloud is warm, with a median excitation temperature of ˜24 K; the Orion Bar has the highest excitation temperature gas, at >80 K. The C18O excitation temperature correlates well with the dust temperature (to within 40 per cent). The C18O emission is optically thin, and the 13CO emission is marginally optically thick; despite its high mass, OMC 1 shows the lowest opacities. A virial analysis indicates that Orion A is too massive for thermal or turbulent support, but is consistent with a model of a filamentary cloud that is threaded by helical magnetic fields. The variation of physical conditions across the cloud is reflected in the physical characteristics of the dust cores. We find similar core properties between starless and protostellar cores, but variations in core properties with position in the filament. The OMC 1 cores have the highest velocity dispersions and masses, followed by OMC 2/3 and OMC 4. The differing fragmentation of these cores may explain why OMC 1 has formed clusters of high-mass stars, whereas OMC 4 produces fewer, predominantly low-mass stars.

Effects of nutritional restrictions during post-hatching development on adrenocortical function in western scrub-jays (Aphelocoma californica).  

PubMed

Altricial birds grow rapidly during post-hatching period and are developmentally sensitive to variations in food supply. Limited food results in elevated corticosterone levels in chicks of semi-precocial birds but it is not clear whether altricial songbirds show similar adrenocortical stress response to nutritional restrictions during early development. It is also unknown how nutritional stress during early development affects the adrenocortical function later in life in altricial birds which show tremendous variation in the magnitude of adrenocortical stress response. Using western scrub-jays (Aphelocoma californica), we experimentally demonstrated that moderate food restrictions (65% of ad libitum) during post-hatching development caused significant elevation of baseline corticosterone levels in nest-bound chicks. Compared to controls, 1-year-old scrub-jays that experienced nutritional deficits during post-hatching development also showed a marginally significant trend to have stronger adrenocortical stress response and significantly greater degree of fluctuating asymmetry in bone and feather measurements. Thus, our results demonstrated that developing altricial birds show adrenocortical response to nutritional deficits, which might produce long-term changes in responsiveness of the adrenal system. Our study suggests that baseline corticosterone levels are a good indicator of physiological conditions of developing birds and that individual variance in adrenocortical stress response commonly observed in many species might, at least in part, be explained by environmental conditions during early development. Considering that nutritional restrictions during early development are linked to many permanent changes including impaired cognitive abilities, corticosterone levels in developing young might be a reliable predictor of their future fitness.

The motion of OB stars closer than 2 kpc from the Sun is analysed. It shows that the local system of young stars lags behind the LSR by 4-5 km s^-1, and that its motion may be explained as local nearly rigid-body rotation in the same direction as the overall galactocentric rotation. The residual velocities reveal local expansions in the Scorpius-Centaurus and Orion regions and a motion of these two regions away from each other. The computed orbits show that 10-12 Myr ago the progenitors of Scorpius-Centaurus OB associations were concentrated within a minimum volume. They were also closer to the progenitors of the OB association in Orion, residing all together within a sheet-like region elongated in the l = 20-200° direction. Free expansion, supershells related to OB associations and a supershell related to a hypernova event have been examined as possible models. No agreement with observation has been reached yet; more variants should be tested in the future.

Behaviour and stability of Trivelpiece-Gould modes in non-neutral plasma containing small density fraction of background gas ions  

SciTech Connect

It is shown that the frequencies of Trivelpiece-Gould (TG) modes in non-neutral plasma can get into the low-frequency range due to the Doppler shift caused by plasma rotation in crossed fields. TG modes interact with the ion modes that leads to plasma instability. In paper the frequency spectrum of 'cold' electron plasma completely filling a waveguide and containing small density fraction of ions of background gas is determined numerically. For ions the kinetic description is used. Oscillations having azimuthal number m= 2 are considered. In this case both low- and upper-hybrid TG modes get into the low-frequency range. The spectrum consists of families of 'modified' ion cyclotron (MIC) modes and electron TG modes with the frequencies equal to hybrid frequencies with the Doppler shift. The growth rates of upper-hybrid modes are much faster than the growth rates of low-hybrid and MIC modes.

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.

Repeatability of baseline and stress-induced corticosterone levels across early life stages in the Florida scrub-jay (Aphelocoma coerulescens).  

PubMed

Recent studies have posited that the pattern of glucocorticoid secretion within an individual represents a stable, fixed physiological trait. To test this hypothesis, we assessed the repeatability of baseline and stress-induced corticosterone (CORT) secretion across developmental stages and years in Florida scrub-jays. We sampled individuals from multiple cohorts repeatedly from the age of 11 days post-hatch up to 4 years of age. We found a significant degree of repeatability within individuals in stress-induced corticosterone levels, i.e., the amount of hormone secreted during a standardized stress protocol (corrected integrated corticosterone). However, baseline corticosterone levels were not statistically repeatable, although there was some indication that nestling levels predicted levels at 1 year of age. The results of this study indicate that stress-induced CORT levels are consistent within individual scrub-jays, and the degree to which a young jay mounts an acute stress response appears to be somewhat "set" by the age of nutritional independence. Thus stress-induced corticosterone secretion appears to be a stable, repeatable trait within individuals and as such may be subject to natural selection. PMID:21295036

Conservation as virtue: a scientific and social process for conservation ethics.  

PubMed

Most scientists take ethical arguments for conservation as given and focus on scientific or economic questions. Although nature conservation is often considered a just cause, it is given little further consideration. A lack of attention to ethical theory raises serious concerns for how conservation scientists conceive and practice ethics. I contrast two common ways scientists approach ethics, as demonstrated in the writings of Stephen Jay Gould and E. O. Wilson. Gould casts severe doubt as to whether any ethics are possible from science, whereas Wilson proposes science as the only path to ethics. I argue these two methods ultimately limit popular support for conservation and offer Alasdair MacIntyre's "virtue ethics" as an alternative. Unlike Gould and Wilson, MacIntyre provides an ethical theory that reconciles scientific inquiry and social traditions. Recent studies of the Civil Rights Movement in the United States affirm MacIntyre's claims and provide important insights for conservation today. These accounts argue that social solidarity and political success against segregation were possible only as rooted in the particular language, logic, and practices of a robust cultural tradition. If correct, conservation science should attend to several questions. On what basis can conservation achieve widespread cultural legitimacy? What are the particular social currencies for a conservation ethic? What role does science play in such a scheme? MacIntyre's careful positioning of scientific and social traditions provides a hopeful ethical direction for conservation. PMID:17002754

The development of caching and object permanence in Western scrub-jays (Aphelocoma californica): which emerges first?  

PubMed

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.

Out of Gondwanaland; the evolutionary history of cooperative breeding and social behaviour among crows, magpies, jays and allies  

PubMed Central

Cooperative breeding is comparatively rare among birds in the mainly temperate and boreal Northern Hemisphere. Here we test if the distribution of breeding systems reflects a response to latitude by means of a phylogenetic analysis using correlates with geographical range among the corvids (crows, jays, magpies and allied groups). The corvids trace their ancestry to the predominantly cooperative ‘Corvida’ branch of oscine passerines from the Australo-Papuan region on the ancient Gondwanaland supercontinent, but we could not confirm the ancestral state of the breeding system within the family, while family cohesion may be ancestral. Initial diversification among pair-breeding taxa that are basal in the corvid phylogeny, represented by genera such as Pyrrhocorax and Dendrocitta, indicates that the corvid family in its current form could have evolved from pair-breeding ancestors only after they had escaped the Australo-Papuan shield. Within the family, cooperative breeding (alloparental care/family cohesion) is strongly correlated to latitude and its predominance in species maintaining a southerly distribution indicates a secondary evolution of cooperative breeding in the lineage leading away from the basal corvids. Multiple transitions show plasticity in the breeding system, indicating a response to latitude rather than evolutionary inertia. The evolutionary background to the loss of cooperative breeding among species with a northerly distribution is complex and differs between species, indicating a response to a variety of selection forces. Family cohesion where the offspring provide alloparental care is a main route to cooperatively breeding groups among corvids. Some corvid species lost only alloparental care, while maintaining coherent family groups. Other species lost family cohesion and, as a corollary, they also lost the behaviour where retained offspring provide alloparental care. PMID:16600890

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.

Estuarine foraminiferal biofacies pattern compared to the brackish ichnofacies model: Port Stephens, southeast Australia  

NASA Astrophysics Data System (ADS)

Port Stephens, located in SE Australia, is a shallow estuary with an outer and inner basin separated by a narrow channel. Foraminiferal biofacies distribution reveals this complex physical environment. The flood-tide delta forms a transition between the wave-dominated open coast and the microtide-dominated estuary. Sand wave dynamics cause a shifting substrate, resulting in allochthonous assemblages of calcareous shelf species transported into the bay through a wide entrance. The muddy central basin is heavily bioturbated, and allows for an in-situ, mixed calcareous and agglutinated assemblage of a progressively more estuarine character. Burial of organic matter and increased bioturbation permits infaunal species to increase in abundance, but promotes calcium carbonate dissolution. The bayhead delta of the Karuah River is characterized by lithic-rich substrates that are associated with robust calcareous species. Tidal cycles, combined with low river-flux, provide nearly fully marine conditions far upstream into the Karuah River. Marginal regions, from sandy/muddy tidal flats to marsh, show distinct assemblages of opportunistic species that respond to tidal exposure, substrate variations, organic matter flux and salinities. Early diagenetic taphonomic loss, closely linked with bioturbation, needs to be considered in interpretations of microfossil assemblages. Foraminiferal biofacies analysis, in combination with the brackish-water ichnology model, is a powerful tool for recognizing Mesozoic marginal marine environments. Port Stephens, with its environmental complexity, offers a valuable modern analogue for estuarine deposits of the geological past.

A first-generation microsatellite-based genetic linkage map of the Siberian jay (Perisoreus infaustus): insights into avian genome evolution  

PubMed Central

Background Genomic resources for the majority of free-living vertebrates of ecological and evolutionary importance are scarce. Therefore, linkage maps with high-density genome coverage are needed for progress in genomics of wild species. The Siberian jay (Perisoreus infaustus; Corvidae) is a passerine bird which has been subject to lots of research in the areas of ecology and evolutionary biology. Knowledge of its genome structure and organization is required to advance our understanding of the genetic basis of ecologically important traits in this species, as well as to provide insights into avian genome evolution. Results We describe the first genetic linkage map of Siberian jay constructed using 117 microsatellites and a mapping pedigree of 349 animals representing five families from a natural population breeding in western Finland from the years 1975 to 2006. Markers were resolved into nine autosomal and a Z-chromosome-specific linkage group, 10 markers remaining unlinked. The best-position map with the most likely positions of all significantly linked loci had a total sex-average size of 862.8 cM, with an average interval distance of 9.69 cM. The female map covered 988.4 cM, whereas the male map covered only 774 cM. The Z-chromosome linkage group comprised six markers, three pseudoautosomal and three sex-specific loci, and spanned 10.6 cM in females and 48.9 cM in males. Eighty-one of the mapped loci could be ordered on a framework map with odds of >1000:1 covering a total size of 809.6 cM in females and 694.2 cM in males. Significant sex specific distortions towards reduced male recombination rates were revealed in the entire best-position map as well as within two autosomal linkage groups. Comparative mapping between Siberian jay and chicken anchored 22 homologous loci on 6 different linkage groups corresponding to chicken chromosomes Gga1, 2, 3, 4, 5, and Z. Quite a few cases of intra-chromosomal rearrangements within the autosomes and three cases of inter-chromosomal rearrangement between the Siberian jay autosomal linkage groups (LG1, LG2 and LG3) and the chicken sex chromosome GgaZ were observed, suggesting a conserved synteny, but changes in marker order, within autosomes during about 100 million years of avian evolution. Conclusion The constructed linkage map represents a valuable resource for intraspecific genomics of Siberian jay, as well as for avian comparative genomic studies. Apart from providing novel insights into sex-specific recombination rates and patterns, the described maps – from a previously genomically uncharacterized superfamily (Corvidae) of passerine birds – provide new insights into avian genome evolution. In combination with high-resolution data on quantitative trait variability from the study population, they also provide a foundation for QTL-mapping studies. PMID:19121221
