    other environments, including those from gravel-bed rivers. None of the radar patterns observed in river channel environments were found on any of the alluvial fans surveyed. The objective of the second part of the thesis is the analysis of the large-scale, three dimensional internal architecture and depositional history of Cheekye Fan in southwestern British Columbia. The fan receives sediments from debris flows which represent a hazard for transportation and residential development on its surface. GPR proved to be an efficient technique for analysing the large-scale internal architecture of Cheekye Fan. Fan sediments overlie till and undulating bedrock in the northern and eastern fan sector. Two architectural components were defined: subaqueously-deposited fan-delta sediments and subaerial alluvial-fan sediments. Fan sediments were tentatively further divided into: (a) matrix-rich diamicton that appears predominant at the core of the fan and at lower stratigraphic horizons, suggesting bouldery rock-slide or debris flow origin, and (b) horizontally-bedded sheetflood sand and gravel dominating the upper 20--25 m of the stratigraphic column. Based on GPR data, radiocarbon dating and test-pit information, the post-glacial depositional history and evolution of Cheekye Fan is as follows. It is estimated that 90% of fan volume was deposited prior to 6000 years BP. Sediment availability declined after ca. 6000 yr. BP and fan growth slowed towards equilibrium. Although the last major debris flow which reached lower Cheekye Fan surface occurred at about 1300 yr. BP, Cheekye Fan is essentially a paraglacial fan, largely a product of the geological past. This fact should be taken into consideration when making future hazard estimates. Based on subsurface information there is little similarity between the early and late Holocene rates of deposition.

    Rivers flowing from glacier-clad Quaternary volcanoes in southwestern British Columbia have high sediment loads and anabranching and braided planforms. Their floodplains aggrade in response to recurrent large landslides on the volcanoes and to advance of glaciers during periods of climate cooling. In this paper, we document channel instability and aggradation during the last 200 years in lower Cheakamus River valley. Cheakamus River derives much of its flow and nearly all of its sediment from the Mount Garibaldi massif, which includes a number of volcanic centres dominated by Mount Garibaldi volcano. Stratigraphic analysis and radiocarbon and dendrochronological dating of recent floodplain sediments at North Vancouver Outdoor School in Cheakamus Valley show that Cheakamus River aggraded its floodplain about 1-2 m and buried a valley-floor forest in the early or mid 1800s. The aggradation was probably caused by a large (ca. 15-25×10 6 m 3) landslide from the flank of Mount Garibaldi, 15 km north of our study site, in 1855 or 1856. Examination of historical aerial photographs dating back to 1947 indicates that channel instability triggered by this event persisted until the river was dyked in the late 1950s. Our observations are consistent with data from many other mountain areas that suggest rivers with large, but highly variable sediment loads may rapidly aggrade their floodplains following a large spike in sediment supply. Channel instability may persist for decades to centuries after the triggering event.

    Four white sturgeon were collected from the upper Fraser River near Prince George, British Columbia, Canada, in the fall of 199a and 1992. Two additional fish were taken from the Fraser River near Williams Lake, some 250 km downstream of Prince George. Samples of white muscle, red muscle, liver, and roe were analyzed for metals, polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), non-ortho and mono-ortho polychlorinated biphenyls (PCBs), and chlorophenols to determine whether the tissues of this species were acceptable for human consumption. The concentrations of mercury in the white muscle and liver of several fish from the upper Fraser River exceeded the provincial tissue residue criteria for people who consumed low quantities of fish. The concentrations of PCDDs, PCDFs, and coplanar PCBs (expressed as 2,3,7,8-tetrachlorodibenzo-p-dioxin toxic equivalents) in red muscle and liver of these fish exceeded the Health Canada working guidelines for the protection of human health. By comparison, white sturgeon collected in the lower Fraser River had much lower concentrations of metals and organic contaminants. The differences in contaminant burdens in fish from the two widely separated reaches of the river reflect their proximity to or distance from known contaminant sources.

    Macroinvertebrate communities in Western European rivers have changed substantially in recent decades. Understanding the causes is challenging because improvements in water quality have coincided with climatic variations over this period. Using data covering >2300 rivers and 21 years (1991-2011) across England and Wales, we analysed family-level distributions and nationwide trends in prevalence (proportion of sampling locations where an organism was present) to diagnose the causes of ecological change. Our aims were to: (i) reveal the taxa driving assemblage-level trends; (ii) identify the main changes in family-level prevalence and distribution patterns; and (iii) test whether changes were accounted for by improving water quality, increasing temperatures or variations in discharge. While previous analyses revealed increasing richness among British river invertebrates, a partial turnover of taxa is now evident. Two distinct components of temporal trend have comprised: (i) overall increases or decreases in taxon prevalence over 21 years, which correlated with pollution sensitivity and discharge; and (ii) short-term variations in prevalence that correlated primarily with temperature and nutrient concentrations. The longer-term changes in prevalence were reflected in expansions or contractions in families' distributions linked to water quality, with little evidence of shifts consistent with increasing temperatures. Although these monitoring data had limitations (e.g., family-level data, few headwaters), they provide no clear evidence of long-term climate effects on invertebrates; the one feature consistent with climate warming - a small northward expansion of the range of many taxa - was accounted for by large improvements in water quality in northern England. Nevertheless, changes linked to discharge and temperature over the shorter-term (<2 years) point to the climatic sensitivity of invertebrate communities. It is therefore likely that any long-term climatic

    The aim of this study is to examine the annual regime of channel scour and fill by monitoring bed-elevation changes in a reach of Squamish River in southwestern British Columbia, Canada. Sonar surveys of 13 river cross-sections in a sandy gravel-bed single-channel study reach were repeated biweekly over a full hydrologic year (1995/6). The survey results show that bedload movement occurs as waves or pulses forming bedwaves that appear to maintain an overall coherence with movement downstream. These bedwaves propagate downstream by a mode here termed pulse scour and pulse fill, a process distinguished from the conventional mode of scour and fill commonly associated with flood events (here termed local scour and local fill). Bedwave celerity was estimated to be about 15.5 m d-1 corresponding to a bedwave residence time in the study reach of almost one hydrologic year. The total amount of local bed-elevation change ranged between 0.22 m and 2.41 m during the period of study. Analysis of the bed-elevation and flow data reveals that, because of the bedware phenomenon, there is no simple relation between the mean bed-elevation and discharge nor any strong linear correlation among cross-sectional behaviour. The bed-elevation data also suggest that complex changes to the bed within a cross-section are masked when the bed is viewed in one dimension, although no definitive trends in bed behaviour were found in the two-dimensional analysis. Although a weak seasonal effect is evident in this study, the bed-elevation regime is dominated by sediment supply-driven fluctuations in bedload transport occurring at timescales shorter than the seasonal fluctuation in discharge. The study also indicates that bed-elevation monitoring on Squamish River, and others like it, for purposes of detecting and measuring aggradation/degradation must take into account very considerable and normal channel-bed variability operating at timescales from hours to months.

    Phosphorus (P) concentration and flow data gathered during the 1990s for a range of British rivers were used to determine the relative contributions of point and diffuse inputs to the total P load, using the Load Apportionment Model (LAM). Heavily urbanised catchments were dominated by sewage inputs, but the majority of the study catchments received most of their annual phosphorus load from diffuse sources. Despite this, almost 80% of the study sites were dominated by point source inputs for the majority of the year, particularly during summer periods when eutrophication risk is greatest. This highlights the need to reduce sewage P inputs to improve the ecological status of British rivers. These modelled source apportionment estimates were validated against land-use data and boron load (a chemical marker for sewage). The LAM was applied to river flow data in subsequent years, to give predicted P concentrations (assuming no change in P source inputs), and these estimates were compared with observed concentration data. This showed that there had been significant reductions in P concentration in the River Thames, Aire and Ouse in the period 1999 to 2002, which were attributable to the introduction of P stripping at sewage treatment works (STW). The model was then used to forecast P concentrations resulting from the introduction of P removal at STW to a 2 or 1mgl(-1) consent limit. For the urbanised rivers in this study, the introduction of phosphorus stripping to a 1mgl(-1) consent level at all STW in the catchment would not reduce P concentrations in the rivers to potentially limiting concentrations. Therefore, further sewage P stripping will be required to comply with the Water Framework Directive. Diffuse P inputs may also need to be reduced before some of the highly nutrient-enriched rivers achieve good ecological status. PMID:20547413

    Synoptic weather patterns that enhance water vapour transport over North Pacific Ocean are common triggers for autumn flooding events in coastal British Columbia (BC). The bulk of this water vapor transport takes place through narrow corridors known as atmospheric rivers (ARs) that occur within the warm conveyor belt of extratropical cyclones. Global climate models (GCMs) simulate ARs to varying degrees, however, all GCMs can simulate the synoptic patterns that favor ARs development. Thus by looking into the synoptic patterns in GCMs one can indirectly investigate future changes in frequency and intensity of AR events, a goal that we have set for this study. First we evaluate the performance of five GCMs in simulating the synoptic patterns responsible for AR-extreme events (landfalling ARs in BC with extreme precipitation over the province). As reference data we used four reanalysis data-sets for the period 1979-2010. With the use of a clustering algorithm we identified characteristic daily patterns of integrated vapour transport (IVT) over the North Pacific Ocean, and further identified the IVT patterns linked to AR-extreme events. We find that for the period 1974-2005 all five GCMs are relatively unsuccessful in simulating the frequencies of these patterns, as well as total precipitation during the AR-extreme events. Despite the large range of projections and uncertainties, better performing GCMs agree in their projections for the end of the 21st century, simulating more frequent AR-extreme events, as well higher precipitation totals during these events. In the best performing model ensemble of three GCMs, the projections according to RCP4.5 emission scenario reveal an increase of AR-extreme events from 18% per extended fall season (Sep-Dec) in 1974-2005 to 22% in 2070-2100, while the seasonal (Sep-Dec) AR-extreme total precipitation averaged over BC increases by 44% between the two periods.

    Chemical and stable isotope compositions of natural gases are key parameters for characterizing gas and hydrocarbon reservoirs. Produced gases were obtained from eight wells at multi-well pad sites located in the Horn River Basin (HRB), NE British Columbia. Shale gas wells were drilled and completed in the Devonian Muskwa, Otter Park and Evie Formations of the HRB, and gases collected as time series over short term (~50 days) and long term periods (~ 1250 days). δ13C of gases from HRB formations confirm high thermal maturity and the shale gases frequently showed partial or full isotope reversals among hydrocarbon components. A 10‰ variation in δ13C values of methane was observed during production. In general, during early phases of production shale gases appear enriched in 12C compared to gases sampled at later stages and δ13Cmethane values were approximately between -38‰ and -35‰ during times up to 50 days. The majority of cases of carbon isotope reversals between methane and ethane components of gases (δ13Cmethane > δ13Cethane) were observed at times greater than 100 days, while ethane and propane reversals were common throughout production. Gas production rates differed significantly among the sampled wells from ~ 50 to 400 e3m3/d. Higher rates were frequently associated with gases showing 12Cmethane enrichment. Subsequent to periods of well 'shut in' a change in the carbon isotope composition was detected with enrichment in 13Cmethane of gases. Carbon isotope signatures of produced gases likely reflect a combination of both the in-situ shale gas isotope signature as well as effects of isotope fractionation which may occur during transport through pores and fractures of the shale.

    The declining population of Kootenai River white sturgeon, which was listed as an Endangered Species in 1994, has prompted a recovery team to assess the feasibility of various habitat enhancement scenarios to reestablish white sturgeon populations. As the first phase in this assessment, the U.S. Geological Survey collected stream channel cross-section and longitudinal data during 2002—03 at about 400 locations along the Kootenai River from Libby Dam near Libby, Montana, to where the river empties into Kootenay Lake near Creston, British Columbia, Canada. Survey control stations with a horizontal and vertical accuracy of less than 0.1 foot were established using a global positioning system (GPS) prior to collection of stream channel cross-section data along the Kootenai River. A total of 245 cross sections were surveyed. Six cross sections upstream from Kootenai Falls were surveyed using a total station where the river was too shallow or dangerous to navigate by vessel. The remaining 239 cross sections were surveyed by interfacing real-time GPS equipment with an echo sounder to obtain bathymetric data and with a laser range- finder to obtain streambank data. These data were merged, straightened, ordered, and reduced in size to be useful. Spacing between these cross sections ranged from about 600 feet in the valley flat near Deep Creek and Shorty Island and near bridges to as much as several miles in other areas. These stream channel cross sections will provide information that can be used to develop hydraulic flow models of the Kootenai River from Libby Dam, Montana, to Queens Bay on Kootenay Lake in British Columbia, Canada.

    A field study to examine the statistical character of dune morphology and the correlation among dune morphology, discharge, and flow resistance was conducted in a meandering reach of Lillooet River, near Pemberton, British Columbia, Canada. The field season spanned the 1995/1996 hydrologic year with sample day discharge events ranging between 33 and 425 m 3 s -1. Surveys of the bed morphology along the thalweg in two dune fields (A and B) were completed using an echo sounder with chart recorder that enabled the measurement of more than 4000 dunes. Dune height ranged between 0.08 and 0.96 m, length between 2.01 and 20.99 m, and steepness between 0.02 and 0.10. Histograms of each dune shape (height, length, steepness) sample most often displayed positive skewness and non-Gaussian distributions (Gamma, Beta, and Weibull); median sample height and length histograms displayed positive skewness; and steepness was nearly Gaussian. Histograms of all dimensionless dunes (i.e., measurement divided by average measurement of sample) were Gaussian and slightly leptokurtic. Neither the height nor length of dunes measured in this investigation were successfully predicted by the empirical models of Allen [Allen, J.R.L., 1984. Developments in Sedimentology. Sedimentary Structures: Their Character and Physical Basis, 2nd edn. Elsevier, New York, vol. 30 (A and B), 1256 pp.], Fredsøe [J. Hydraul. Div., Am. Soc. Civ. Eng. 108(HY8) (1982) 932.], or Yalin [J. Hydraul. Div., Am. Soc. Civ. Eng. 90(HY5) (1964) 105.]. Least-squares regression models for dune-height relations produced here are similar to models published by other field researchers; regression models for dune length only conform to those developed elsewhere if the discharge of the study rivers was similar. The energy gradient in dune field A varied within a smaller range than in field B, enabling dune size to become more fully equilibrated with respect to flow environment. Although the average Froude numbers were much less

    Floods are a recurring natural hazard responsible for large socioeconomic losses globally. In mid-latitude locations, such as Western North America and Europe, heavy precipitation and floods, are connected to intense water vapor transport in extra-tropical cyclones called atmospheric rivers (ARs). This AR region is narrow (on the order of 300-500 km wide) and transports the majority of the poleward moisture flux. Given the strong link between ARs and floods on the west coast of North America, it is the aim of this research to determine if ARs are responsible for hydrohazards in British Columbia and Alaska.Using satellite measurements, atmospheric reanalyses, and in-situ observations we undertake a hydrometeorological analysis on two major flood events, namely the Bella Coola flood in British Columbia in September 2010 in which 10 inches (250mm) of rain fell in 36 hours, and an Alaskan event that produced over 50 inches (1250 mm) of precipitation in the month of September 2012 (mostly in two landfalling ARs), and led to record river stage heights. Furthermore, the Alaskan event resulted in one fatality and $35M in damages to buildings, homes, and infrastructure.Preliminary results suggest that AR conditions were present during these events, and are therefore likely to be important for hydrohazards more generally in British Columbia and Alaska. As the enhanced water vapor transport in the ARs encountered the steep terrain in these regions orographic enhancement of rainfall occurred resulting in record rainfall totals and floods. The occurrence of these events in September (earlier than noteworthy AR events in the U.S. West Coast farther south) may also relate to the earlier nascence of the winter circulation pattern in northern latitudes.

    Impacts of global climate change on water resources systems are assessed by downscaling coarse scale climate variables into regional scale hydro-climate variables. In this study, a new multisite statistical downscaling method based on beta regression (BR) is developed for generating synthetic precipitation series, which can preserve temporal and spatial dependence along with other historical statistics. The beta regression based downscaling method includes two main steps: (1) prediction of precipitation states for the study area using classification and regression trees, and (2) generation of precipitation at different stations in the study area conditioned on the precipitation states. Daily precipitation data for 53 years from the ANUSPLIN data set is used to predict precipitation states of the study area where predictor variables are extracted from the NCEP/NCAR reanalysis data set for the same interval. The proposed model is applied to downscaling daily precipitation at ten different stations in the Campbell River basin, British Columbia, Canada. Results show that the proposed downscaling model can capture spatial and temporal variability of local precipitation very well at various locations. The performance of the model is compared with a recently developed non-parametric kernel regression based downscaling model. The BR model performs better regarding extrapolation compared to the non-parametric kernel regression model. Future precipitation changes under different GHG (greenhouse gas) emission scenarios also projected with the developed downscaling model that reveals a significant amount of changes in future seasonal precipitation and number of wet days in the river basin.

    Semipermeable membrane devices (SPMD) are sampling devices comprised of thin wall polyethylene tubing that encloses a thin film of lipid, triolein. SPMDs have been used successfully to monitor non-polar industrial pollutants from air, water, and sediments. Chemical contaminants dissolved in water dialyze into the lipid mimicking bioconcentration mechanisms in aquatic organisms. The authors have deployed SPMDs at several sites in the water column of the lower Fraser River and the Harisson River, a control site, to assess bioavailability and to determine sources of polychlorinated dibenzo-p-dioxins (PCDD), dibenzofurans (PCDF), and mono-ortho and non-ortho substituted polychlorinated biphenyls (PCB). SPMD sampling was performed during similar time periods in the summers of 1992 and 1994. PCDDs/Fs and PCBs were extracted from the lipid of the SPMDs using in-house developed methodology and extracts were analyzed and quantitated by HRGC/HRMS. The analytical data were inter-compared for characteristic congener distribution patterns and concentration differences of prominent PCDD/Fs and PCBs congeners between sites and sampling years. River flow rates, as calculated from the IOS Ages/Woollard Fraser River model, were considered for the inter-site comparisons. Relative congener composition from each sample was similar from site to site within a sampling year. Overall levels of prominent contaminants, TCDF and PCB 118 and 105, dropped significantly from 1992 to 1994. Comparisons between the reference site and the Fraser river data differentiate between atmospheric and point source contamination of the river. PCDD/Fs and PCBs were detected in the tissues of two species of Fraser River resident fish, their relation to the SPMD data will be discussed.

    The possible effects of changing climate on a southern and a north-eastern English river (the Thames and the Yorkshire Ouse, respectively) were examined in relation to water and ecological quality throughout the food web. The CLASSIC hydrological model, driven by output from the Hadley Centre climate model (HadCM3), based on IPCC low and high CO(2) emission scenarios for 2080 were used as the basis for the analysis. Compared to current conditions, the CLASSIC model predicted lower flows for both rivers, in all seasons except winter. Such an outcome would lead to longer residence times (by up to a month in the Thames), with nutrient, organic and biological contaminant concentrations elevated by 70-100% pro-rata, assuming sewage treatment effectiveness remains unchanged. Greater opportunities for phytoplankton growth will arise, and this may be significant in the Thames. Warmer winters and milder springs will favour riverine birds and increase the recruitment of many coarse fish species. However, warm, slow-flowing, shallower water would increase the incidence of fish diseases. These changing conditions would make southern UK rivers in general a less favourable habitat for some species of fish, such as the Atlantic salmon (Salmo salar). Accidental or deliberate, introductions of alien macrophytes and fish may change the range of species in the rivers. In some areas, it is possible that a concurrence of different pressures may give rise to the temporary loss of ecosystem services, such as providing acceptable quality water for humans and industry. An increasing demand for water in southern England due to an expanding population, a possibly reduced flow due to climate change, together with the Water Framework Directive obligation to maintain water quality, will put extreme pressure on river ecosystems, such as the Thames.

    Permanent river training structures have stabilized the mouth of the Fraser River and largely isolated the Roberts Bank sector of the Fraser River delta from sandy sediment supply. In a study to determine the susceptibility to erosion of the delta nearshore and associated infrastucture, the entire delta front has been mapped using multibeam sonar. High-resolution morphological maps of the nearshore reveal a range of bedforms, dominated by the strong tidal currents that sweep the delta front. Certain sectors of the nearshore are, however, dominated by erosional features including outcropping beds. Numerical modeling, using the SEDTRANS96 program, indicates that wave motions influence sediment transport in water depths less than 15 m during the moderate fetch-limited winter storms typical of the region. Wave, current profile, suspended sediment and seabed imagery data were collected at a site in 10 m water depth as a calibration for further sediment transport modeling. Preliminary results indicate bedload and suspended sediment transport occurred in response to both tidal currents and combined wave- and current conditions.

    The Ice River Alkaline Complex is a late Paleozoic intrusion of mafic alkaline rocks, syenite, and carbonatite exposed in southeastern British Columbia, Canada. The complex intrudes Cambrian and Ordovician shales, slates, and limestones of the Chancellor and Ottertail Formations and the McKay Group. We examined the alkaline complex and adjacent country rocks using Airborne Visible-Infrared Imaging Spectrometer (AVIRIS) data. The data were first calibrated to relative reflectance and then used to spectrally map mineralogies in the study area by using a linear spectral unmixing program. This technique models each pixel spectrum in an AVIRIS image as a linear combination of unique endmember spectra. We selected endmember spectra from well-exposed and spectrally distinct mineralogic units, vegetation, and snow. Four of the endmembers reflect mineralogic variations within the McKay group in the study area, and may represent lateral and vertical variations of sedimentary or metamorphic facies. Otherwise, the resultant spatial distribution of endmembers shows generally close agreement with the published geologic map, although, in several places, our image-map is more accurate than the published map.

    A group of spinel peridotite xenoliths from West Kettle River, British Columbia, represents essentially undepleted to moderately depleted lithospheric mantle rocks in terms of major and compatible trace elements. Whole rock Sr isotopic composition for most of these xenoliths, and whole rock Sm-Nd isotopic composition and LREE contents for some of them, seem to have been perturbed by near-surface processes. Sr and Nd isotopic results for acid-cleaned clinopyroxenes separated from these spinel peridotites reveal an isotopically mid-ocean ridge basalt (MORB)-like mantle. Seven spinel lherzolites gave Nd model ages of 1.5-3.6 Ga, similar to MORB, and on a Sm-Nd isotope diagram plot close to a reference Nd isochron with an age of 0.7 Ga and an initial {var epsilon}{sub Nd} of +7. These features likely resulted from multiple mantle depletion. The isotopic similarities of these xenoliths with MORB suggest that this area is underlain by oceanic lithospheric mantle, possibly accreted to North America during the mid-Jurassic. The Nd isochron age could record the time when the oceanic lithosphere was isolated from the asthenosphere. Recent enrichment event may have acted on such a depleted mantle, as indicated by the low Sm/Nd ratios of two spinel harzburgites.

    A detailed record of channel profiles, slopes, and stream discharge on Lillooet River provides an opportunity to study the effects of natural and artificial channel changes that have occurred over the past century. We analyze the long-term effects of channel alterations that may affect flood hazard. In the mid 1940s several meanders were artificially severed, side channels blocked off, and the level of downstream Lillooet Lake was lowered. These measures were thought to increase hydrologic efficiency and decrease flood risk in the largely agricultural valley. Between 1947 and 1994 average channel width in the upper reaches decreased by 50%, most of which occurred by the late 1950s. Between 1945 and 1969 Lillooet River degraded its bed elevation by 3-4 m (12.5 to 16.7 cm a- 1) in the upper reaches and up to 2 m (8.3 cm a- 1) in the lower reaches. This sudden and profound degradation compares to average bed elevation increases of 2.4 cm a- 1 prior to the engineering works. Between 1969 and 1985 the cross section area increased by 22% in the upper reaches and 13% in the lower reaches and decreased to 12% and 8%, respectively, for the time period 1985 to 2000. The increased sediment supply that was caused by channel straightening accelerated delta advance in Lillooet Lake from 7 m a- 1 (1858 to 1948) to 30 m a- 1 for the five-year period following the 1948 channel works. These rates have decreased over time, but with a current advance rate of 10.5 m a- 1 (1986-2009) are still above the long-term average prior to the channel changes. This study demonstrates the time scale, direction, and magnitude of channel changes following significant artificial river alterations. While the initial goal of decreasing flood risk had been achieved in the short term, the lower river apparently is slowly returning to an overall aggradational phase. Ongoing delta advance will ultimately increase channel elevations in the lower reaches and lead to significant flood hazards for populated

    For several years Environment Canada (EC) has carried out a program of water sampling at four stations along the Fraser River and at one station on each of its two principal tributaries, the Thompson and the Nechako. Samples collected at bi-weekly intervals have been analyzed by EC for major and some trace components. Seasonal variation in water composition mainly relates to changes in discharge, this being low during winter and high during early summer snowmelt. Dissolved constituents, Mg, Si, K, Ca, Sr, HCO 3, SO 4 and (NO 3 + NO 2), show moderate variation, being least concentrated during maximum discharge, reflecting dilution of groundwater by melting snow. Factor analysis shows secondary seasonal variation for SO 4, that is related to the importance of deep groundwater as a source, and for (NO 3 + NO 2), precipitated with snow and released during snowmelt. Large amounts of Na and Cl are added in pulp mill effluent. A uniform flux of this effluent, superimposed on a highly variable river discharge, gives rise to greater seasonal variation for Na and Cl than other dissolved constituents. The trace constituents, Fe, Mn, Al, P and Sr, were analyzed by EC in unfiltered water samples by methods that extract the elements from suspended material. Except for Sr, these elements have a high partition factor in favor of suspended over dissolved phases; their results reflect seasonal changes in quantities of suspended material, which can vary by two orders of magnitude.

    The northern portion of the Pacific coastal temperate rainforest (PCTR) is one of the least anthropogenically modified regions on earth and remains in many respects a frontier area to science. Rivers crossing the northern PCTR, which is also an international boundary region between British Columbia, Canada and Alaska, USA, deliver large freshwater and biogeochemical fluxes to the Gulf of Alaska and establish linkages between coastal and continental ecosystems. We evaluate interannual flow variability in three transboundary PCTR watersheds in response to El Niño-Southern Oscillation (ENSO), Pacific Decadal Oscillation (PDO), Arctic Oscillation (AO), and North Pacific Gyre Oscillation (NPGO). Historical hydroclimatic datasets from both Canada and the USA are analyzed using an up-to-date methodological suite accommodating both seasonally transient and highly nonlinear teleconnections. We find that streamflow teleconnections occur over particular seasonal windows reflecting the intersection of specific atmospheric and terrestrial hydrologic processes. The strongest signal is a snowmelt-driven flow timing shift resulting from ENSO- and PDO-associated temperature anomalies. Autumn rainfall runoff is also modulated by these climate modes, and a glacier-mediated teleconnection contributes to a late-summer ENSO-flow association. Teleconnections between AO and freshet flows reflect corresponding temperature and precipitation anomalies. A coherent NPGO signal is not clearly evident in streamflow. Linear and monotonically nonlinear teleconnections were widely identified, with less evidence for the parabolic effects that can play an important role elsewhere. The streamflow teleconnections did not vary greatly between hydrometric stations, presumably reflecting broad similarities in watershed characteristics. These results establish a regional foundation for both transboundary water management and studies of long-term hydroclimatic and environmental change.

    The highly diverse shifting-mosaic of forest patches of an alluvial forest within the Carmanah River valley on the west coast of Vancouver Island, British Columbia was studied to examine the hydrogeomorphic disturbance regime that structures it. We used a landscape-scale analysis to quantify historical channel migrations and changes in the extent of specific forest types. This GIS-based analysis using a 70-year aerial photographic record was complemented by field-based research. Thirty-eight plots containing 4509 trees were sampled for forest structure, age, and elevation above the contemporary channel. These data, including a vegetation chronosequence spanning over 500 years, were used to examine channel and landscape dynamics. Our findings support a general conceptual model that describes cycles of patch development and destruction in unconfined alluvial forests of the Pacific Coastal Ecoregion. Over the past century, Carmanah River has eroded nearly 30% of the alluvial forest in this study area, and approximately 65% over the past 500 years. At least 80% of the 2007 channel was forested area within the past 70 years. Younger landforms were disturbed more frequently than mature forest patches, which suggest that as biogeomorphic succession progresses the likelihood of future disturbance decreases. Estimated half lives of landforms ranged from 24 years for pioneer bars to over 1500 years for old growth terraces. Years of regional high magnitude floods resulted in a net loss of floodplain forest area indicating that disturbance was climate driven in this pluvial watershed, whereby rain events result in flood disturbance that converted forests to channel. These events initiate a subsequent course of vegetation succession and geomorphic development, and often result in the deposition of large wood that modifies the channel environment and contributes to channel avulsion and further hydrogeomorphic disturbance. The composition of the landscape is a reflection of the

    The Yukon River basin is the fourth largest watershed in North America at 831,400 square kilometers (km2). Approximately 126,000 people live within the basin and depend on the Yukon River and its tributaries for drinking water, commerce, subsistence, and recreational fish and game resources. Climate warming in the Arctic and Subarctic regions encompassing the Yukon basin has recently become a concern because of possible far-reaching effects on the ecosystem. Large amounts of carbon and nutrients are stored in permafrost and have potential for release in response to this warming. These changes in carbon and nutrient cycling may result in changes in stream chemistry and productivity, including salmon populations, and ultimately changes in the chemistry and productivity of the Bearing Sea. To address these concerns, the U.S. Geological Survey (USGS) conducted a 5-year comprehensive water-quality study of the Yukon River and its major tributaries starting in 2000. The study included frequent water-quality sampling at a fixed site network as well as intensive sampling along the Yukon River and its major tributaries. This report contains observations of water and sediment quantity and quality of the Yukon River and its tributaries in Canada during 2004. Chemical, biological, physical, and discharge data are presented for the reach of river between Atlin, British Columbia, Canada, and Eagle, Alaska, USA.

    Stomach contents were collected and analysed from 22 bull trout Salvelinus confluentus at the edge of the Chilko Lake and Chilko River in British Columbia, Canada, during spring outmigration of sockeye salmon Oncorhynchus nerka smolts. Twenty of the 22 (>90%) stomachs contained prey items, virtually all identifiable prey items were outmigrant O. nerka smolts and stomach contents represented a large portion (0·0-12·6%) of estimated S. confluentus mass. The results demonstrate nearly exclusive and intense feeding by S. confluentus on outmigrant smolts, and support recent telemetry observations of high disappearance rates of O. nerka smolts leaving large natural lake systems prior to entering high-order unregulated river systems.

    We compare alternative models of sockeye salmon (Oncorhynchus nerka) productivity (returns per spawner) using more than 30 years of catch and escapement data for Bristol Bay, Alaska, and the Fraser River, British Columbia. The models examined include several alternative forms of models that incorporate climatic influences as well as models not based on climate. For most stocks, a stationary stock-recruitment relationship explains very little of the interannual variation in productivity. In Bristol Bay, productivity co-varies among stocks and appears to be strongly related to fluctuations in climate. The best model for Bristol Bay sockeye involved a change in the 1970s in the parameters of the Ricker stock-recruitment curve; the stocks generally became more productive. In contrast, none of the models of Fraser River stocks that we examined explained much of the variability in their productivity.

    Data for selected water quality variables were evaluated for trends at two sampling stations--Flathead River at Flathead, British Columbia (Flathead station) and Flathead River at Columbia Falls, Montana (Columbia Falls station). The results were compared between stations. The analyses included data from water years 1975-86 at the Flathead station and water years 1979-86 at the Columbia Falls station. The seasonal Kendall test was applied to adjusted concentrations for variables related to discharge and to unadjusted concentrations for the remaining variables. Slope estimates were made for variables with significant trends unless data were reported as less than the detection limit. At the Flathead station, concentrations of dissolved solids, calcium, magnesium, sodium, dissolved nitrite plus nitrate nitrogen, ammonia nitrogen (total and dissolved), total organic nitrogen, and total phosphorus increased during the study period. Concentrations of total nitrite plus nitrate nitrogen and dissolved iron decreased during the same period. At the Columbia Falls station, concentrations increased for calcium and magnesium and decreased for sulfate and dissolved phosphorus. No trends were detected for 10 other variables tested at each station. Data for the Flathead station were reanalyzed for water years 1979-86. Trends in the data increased for magnesium and dissolved nitrite plus nitrate nitrogen and decreased for dissolved iron. Magnesium was the only variable that displayed a trend (increasing) at both stations. The increasing trends that were detected probably will not adversely affect the water quality of the Flathead River in the near future. (USGS)

    The Elk River is a mountain watershed located along the eastern border of British Columbia, Canada. The Elk River is confined by railway bridges, roads, and urban areas. Flooding has been a concern in the valley for more than a century. The most recent major flood event occurred in 2013 affecting several communities. River modifications such as riprapped dykes, channelization, and dredging have occurred in an attempt to reduce inundation, with limited success. Significant changes in land cover/land use (LCLU) such as natural state to urban, forestry practices, and mining from underground to mountaintop/valley fill have changed terrain and ground surfaces thereby altering water infiltration and runoff processes in the watershed. Future climate change in this region is expected to alter air temperature and precipitation as well as produce an earlier seasonal spring freshet potentially impacting future flood events. The objective of this research is to model historical and future hydrological conditions to identify flood frequency and risk under a range of climate and LCLU change scenarios in the Elk River watershed. Historic remote sensing data, forest management plans, and mining industry production/post-mining reclamation plans will be used to create a predictive past and future LCLU time series. A range of future air temperature and precipitation scenarios will be developed based on accepted Global Climate Modelling (GCM) research to examine how the hydrometeorological conditions may be altered under a range of future climate scenarios. The GENESYS (GENerate Earth SYstems Science input) hydrometeorological model will be used to simulate climate and LCLU to assess historic and potential future flood frequency and magnitude. Results will be used to create innovative flood mitigation, adaptation, and management strategies for the Elk River with the intent of being wildlife friendly and non-destructive to ecosystems and habitats for native species.

    The Kettle River Basin in South central British Columbia (Canada) is under increasing anthropogenic pressures affecting both water quantity and quality of surface waters and aquifers. We investigated water quality and sources and processes influencing NO3- and SO42- in the Kettle River Basin using a combination of chemical and isotopic techniques. The dominant water type in the Kettle River Basin is Ca-HCO3 with surface waters having total dissolved solids (TDS) concentrations of < 115 mg/L and groundwaters having TDS values of up to 572 mg/L. Based on δ15NNO3andδ18ONO3 values and concentration data, NO3- in surface waters originates primarily from natural soil nitrification processes, with additional influences from anthropogenic activities, such as waste water effluents at sampling locations downstream from population centres. The source of NO3- in groundwater was predominantly nitrification of soil organic matter, although nitrate in a few groundwater samples originated from anthropogenic sources, including manure or septic systems. The dominant source of SO42- in surface water and groundwater samples was the natural oxidation of sulfide minerals. With increasing distance downstream, surface water δ18OSO4 values increase beyond the range of oxidation of sulfide minerals and into the range of soil and atmospheric-derived SO42- that is in part derived from anthropogenic emissions. Hence, we conclude that recent anthropogenic impacts have affected water quality only marginally at only few sites in the Kettle River Basin. The presented data will serve as an excellent baseline against which future impacts can be assessed.

    Over 30 dropsonde transects were performed across atmospheric rivers (ARs) over the eastern Pacific during CalWater 2015. An event in late January allowed first-of-its-kind coordinated dropsonde transects of an AR using the NOAA G-IV aircraft in tandem with the NOAA Ronald H. Brown (RHB), which observed the marine boundary layer during the passage of this major AR. Dropsonde data collected on 22 January 2015 sampled the early stages of the AR, when the AR began making landfall near Vancouver Island, British Columbia. At the same time the RHB collected precipitation and oceanic moisture flux measurements on the warm side of the AR. A second flight on 24 January 2015 sampled the later stages of the AR, again passing over the RHB stationed beneath the AR. During this later period, the AR axis of moisture shifted north-northeast and fanned out along the coast, affecting regions from Northern Washington to Southern Alaska. Multi-day landfalling AR conditions led to flooding in British Columbia and northern Washington. The influence of the coastal orography combined with the shift in AR orientation is examined to understand the orographic control of precipitation that triggered the flooding. In addition, cross section analysis of the AR using dropsonde and reanalysis data are used to better understand the synoptic influences, water vapor transport, and moisture evolution during the lifecycle of the AR. To gain greater insight into AR development and prolonged AR conditions that led to enhanced flooding, a comparison of aircraft and ship data from CalWater 2015 and NOAA Unique CrIS/ATMS Processing System (NUCAPS) retrievals (integrated water vapor, vertical temperature and moisture profiles, and an experimental ATMS-only rain rate product) will be compared for the 22-24 January period.

    Eulachons return to the Fraser River each spring and migrate through the estuary to spawn in freshwater. During this migration they may be subjected to varying water quality conditions due to the discharge of domestic and industrial wastes and land drainage. Fish were captured at five estuarine stations in April 1986 and again at three stations in April/May 1988. The locations were from Steveston, at the river mouth, to Port Mann bridge, 31.0 km upstream, just above saltwater influence. Water samples, whole fish, gonads and pooled livers of both sexes were analyzed separately for selected organochlorine contaminants. Water and tissue samples contained chlorophenols from wood preservation operations and chloroguaiacols from pulp bleaching. Whole fish also contained DDE and DDD, while PCBs were present in some fish gonads in 1986, but not in 1988. With the exception of whole body concentrations of 2,3,4,6-tetrachlorophenol (TeCP), concentrations of pentachlorophenol (PCP), 3,4,5-trichloroguaiacol (3,4,5-TCG), tetrachloroguaiacol (TeCG), DDE and DDD in whole bodies, livers and gonads revealed an increasing trend with distance of the eulachon capture site upstream from the Fraser River mouth. Marked differences occurred in the concentration of contaminants in eulachon livers (for example, levels of 50.8 +/- 42.2 ng g-1 3,4,5-TCG at Steveston, and 446.4 +/- 222.5 ng g-1 at Port Mann). The relatively high lipid content of eulachons suggests them to be potential integrators of low-level contaminants in the Fraser River system. This, and their anadromous life history, recommend them as suitable annual monitors of selected organic compounds. PMID:2084844

    Electromyogram (EMG) radio telemetry was used in conjunction with physiological biopsy to relate prior physiological condition and subsequent swimming energetics and behaviours to passage success of 13 wild adult sockeye salmon Oncorhynchus nerka at a vertical-slot fishway on the Seton River, British Columbia. At the time of capture, plasma lactate, glucose and cortisol levels indicated that fish were not exhibiting unusually high levels of physiological stress. Very few differences existed between successful and unsuccessful fish in body size, initial plasma physiology and energy state and mean swim speed and energy use during passage. Generally, fish did not employ burst swimming during successful or failed attempts at passage, indicating that failure was probably not related to metabolic acidosis. Plasma Na(+) concentration was significantly lower in unsuccessful fish (P < 0.05), which is suggestive of a depressed ionic state or a possible stress component, although values in all fish were within an expected range for migrant adult O. nerka. Nevertheless, six of 13 fish failed to reascend the fishway and remained in the tailrace of the dam for more than a day on average before moving downstream and away from the dam. During this time, fish were observed actively seeking a means of passage, suggesting that there may have been other, undetermined causes of passage failure. PMID:20735634

    Sharp-crested moraines, up to 120 m high and 9 km beyond Little Ice Age glacier limits, record a late Pleistocene advance of alpine glaciers in the Finlay River area in northern British Columbia. The moraines are regional in extent and record climatic deterioration near the end of the last glaciation. Several lateral moraines are crosscut by meltwater channels that record downwasting of trunk valley ice of the northern Cordilleran ice sheet. Other lateral moraines merge with ice-stagnation deposits in trunk valleys. These relationships confirm the interaction of advancing alpine glaciers with the regionally decaying Cordilleran ice sheet and verify a late-glacial age for the moraines. Sediment cores were collected from eight lakes dammed by the moraines. Two tephras occur in basal sediments of five lakes, demonstrating that the moraines are the same age. Plant macrofossils from sediment cores provide a minimum limiting age of 10,550-10,250 cal yr BP (9230 ± 50 14C yr BP) for abandonment of the moraines. The advance that left the moraines may date to the Younger Dryas period. The Finlay moraines demonstrate that the timing and style of regional deglaciation was important in determining the magnitude of late-glacial glacier advances.

    A retrospective carbon (C ) budget for the Fluxnet-Canada coastal BC Station (5 x 5 km Oyster River Area) for the period 1920 to 2005 was developed using the spatially-explicit version of the Carbon Budget Model of the Canadian Forest Sector (CBM-CFS3). CBM-CFS3 is an inventory-based C budget modeling tool that has been used to simulate forest C dynamics at national, regional, and operational scales. A current (circa 2000) forest inventory map for the Oyster River Area was compiled using data provided by forest companies (TimberWest and Island Timberlands). This inventory was overlaid with historic disturbance maps and orthophotographs to generate a coverage of forest cover polygons with unique disturbance histories. A 1920 timber cruise map was then used to help estimate the volume, cover type, and age of the forest in each polygon in 1920. Data were loaded into the CBM-CFS3 initialization routine and the model was then used to simulate the forest dynamics and C budget for the 85-year period. The C budget of the Oyster River Area is strongly tied to its disturbance history. In 1920, old-growth forest covered the majority of the study area and net C flux was neutral or small. In the 1930's and 40's, ground fires, clear-cut harvesting (using railroad logging), and slash burning resulted in a significant loss of biomass C and a substantial flux of C into dead organic matter, the atmosphere, and wood product pools (area net average C loss 5 - 20 Mg C/ha/yr). A gradual recovery of ecosystem C stocks followed this period of high disturbance activity but the area remained a significant C source, and did not become a net C sink until well into the 1950's. From 1960 through 1987 disturbance was minimal and the area remained a C sink (area average net uptake 2 - 6 Mg C/ha/yr). As harvesting of the second-growth forest began in the late 1980's, the C budget of the area was once again dominated by disturbances, albeit buffered by ongoing C uptake by living biomass in the

    The health and physiological condition of anadromous salmon is of concern as their upriver migration requires navigation of human-impacted waterways and metabolism of stored energy reserves containing anthropogenic contaminants. Such factors may affect reproductive success of fish stocks. This study investigates chemical contaminant burdens and select gene expression profiles in Pacific Sockeye (Oncorhynchus nerka) and Chinook (Oncorhynchus tshawytscha) salmon which traverse the Fraser River watershed during their spawning migration. Chemical analyses of muscle tissue and eggs of salmon collected from the lower Fraser River (pre-migration) and from upstream spawning grounds (post-migration) during the 2007 migration revealed the presence of numerous chemical contaminants, including PCBs, dioxins/furans, pesticides, and heavy metals. However, muscle tissue residue concentrations were well below human health consumption guidelines and 2,3,7,8 TCDD toxic equivalents (SigmaTEQs) in salmon eggs, calculated using WHO toxic equivalency factors (WHO-TEFs) for fish health, did not exceed the 0.3pgg(-1) wet weight toxicological threshold level previously associated with 30% egg mortality in salmon populations. Quantitative real-time PCR probes were generated and used to assess differences in abundance of key mRNA transcripts encoding nine gene products associated with reproduction, stress, metal toxicity, and exposure to environmental contaminants. Gene expression profiles were characterized in liver and muscle tissue of pre- and post-migration Sockeye and Chinook salmon. The results of stock-matched animals indicate that dynamic changes in mRNA levels occur for a number of genes in both species during migration and suggest that Sockeye salmon exhibit a greater level of biological stress compared to the Chinook salmon population. Using a male-specific genotypic marker, we found that out of the 154 animals examined, one Sockeye was genotypically male but phenotypically female

    The impact of agriculture, forestry and metal mining on the quality of fine-grained sediment (<63 μm) was investigated in the Quesnel River Basin (QRB) (~11,500 km(2)) in British Columbia, Canada. Samples of fine-grained sediment were collected monthly during the snow-free season in 2008 using time-integrated samplers at replicate sites representative of agriculture, forestry and mining activities in the basin (i.e. "impacted" sites). Samples were also collected from replicate reference sites and also from the main stem of the Quesnel River at the downstream confluence with the Fraser River. Generally, metal(loid) and phosphorus (P) concentrations for "impacted" sites were greater than for reference sites. Furthermore, concentrations of copper (forestry and mining sites), manganese (agriculture and forestry sites) and selenium (agriculture, forestry and mining sites) exceeded upper sediment quality guideline (SQG) thresholds. These results suggest that agriculture, forestry and metal mining activities are having an influence on the concentrations of sediment-associated metal(loid)s and P in the Quesnel basin. Metal(loid) and P concentrations of sediment collected from the downstream site were not significantly greater than values for the reference sites, and were typically lower than the values for the impacted sites. This suggests that the cumulative effects of agriculture, forestry and mining activities in the QRB are presently not having a measureable effect at the river basin-scale. The lack of a cumulative effect at the basin-scale is thought to reflect: (i) the relatively recent occurrence of land use disturbances in this basin; (ii) the dominance of sediment contributions from natural forest and agriculture; and (iii) the potential for storage of contaminants on floodplains and other storage elements between the locations of disturbance activities and the downstream sampling site, which may be attenuating the disturbance signal.

    In British Guiana, the successful eradication of Anopheles darlingi and malaria from the coastal areas has caused a very rapid increase in the population and has favoured a considerable social and economic improvement and expansion of both agriculture and industry. Housing and industrial developments and the constantly expanding rice cultivation have taken over most of the accessible pasture-lands, displacing the livestock which previously abounded around villages and settlements. Mechanization on the roads and in the fields increases daily, and the horse, the mule, the donkey and the ploughing oxen are gradually becoming obsolete.In some areas these changes have already caused such an upset in the balance between the human and the livestock population that A. aquasalis, a very abundant species all along the coast, but until recently entirely "fixed" by the livestock population, is now shifting its attention from livestock to man. On the Demerara river estuary, an area where malaria transmission was interrupted sixteen years ago and where eradication has been continually maintained, this mosquito has been responsible for a sharp, but localized, outbreak of P. vivax malaria. An entirely new epidemiological problem thus presents itself.Environmental changes, introduced and fostered by successful malaria eradication, may thus cause an anopheline species, potentially capable of malaria transmission, but originally inactive and harmless as a vector, to alter its feeding habits and thereby renew transmission. The immediate and long-term significance of some secondary and potential vectors may therefore require renewed evaluation in the planning of malaria eradication campaigns. PMID:14056265

    A range of carbonates exist in terrestrial and freshwater environments that may act as the basis for palaeo-temperature estimation. In many regions, such as Europe, the potential of using freshwater molluscs as a basis for reconstructing Quaternary environments is highly desirable because; 1) they are abundant in a wide range of deposits (interglacial, interstadial and stadial), and 2) isotopic analysis may allow climates to be reconstructed from a small number of individuals rather than extensive assemblages. Work in southern England in monitored river systems has shown that the shells of modern molluscs (Valavata piscinalis, Bithynia tentaculata) form in isotopic equilibrium with river waters during the summer months. This is true for both large river systems such as the Thames and smaller tributary systems and suggests that this proxy could allow the reconstruction of past summer temperatures. The potential of this technique for reconstructing relative temperatures is investigated by studying fossil shell assemblages from 6 of the last 8 interglacials over the last 800,000 years. Analysed samples all come from riverine deposits in southern and eastern England and are chosen from deposits which have known quantified estimates of summer temperatures from a number of biological proxies (beetles, plant macrofossils, vertebrates). There is a general consistency of 18O values from shell assemblages from all the interglacial sites, however, a large deviation from modern shell 18O values is found within assemblages from interglacial deposits which record summer temperatures that are significantly higher (3-6oC warmer) than temperatures in southern day England. The technique, therefore, allows a potential method of identifying periods of enhanced warmth in the Quaternary record. The relationship between shell 18O and water temperature is discussed and methods of quantification are proposed.

    This paper presents results of determinations of polychlorinated dibenzodioxin (PCDD) and polychlorinated dibenzofuran (PCDF) levels in the prey of great blue herons foraging on the Fraser River estuary tidal flats. Observations of herons foraging at Iona and Westham Islands showed that starry flounder (Platichthys stellatus) and Pacific staghorn sculpin (Leptocottus armatus) were the major prey species throughout the year. The paper includes measurements of PCDD/PCDF levels in those two species and others such as redside shiner (Richardsonius balteatus), peamouth chub (Mylocheilus caurinum), and shiner perch (Cymatogaster aggregata). The paper concludes with a discussion of the role of contaminated inshore fish on the entry of PCDD/PCDF into herons.The purpose of the Ecological Monitoring and Assessment Network is to provide information and understanding needed for the sustainable management of Canada`s resources and resource-based industries. This document presents the proceedings of the first meeting of the Network. It includes presentations by federal government representatives on ecological monitoring and research programs in federal departments, reviews of progress in establishing Ecological Science Cooperatives for ecological monitoring and research, presentations on topical workshops, and workshop summaries. The workshops were arranged by ecological issue (biodiversity, climate change, ultraviolet radiation, toxic chemicals, and cumulative effects). They discussed and recommended local and national goals, objectives, and deliverables for ongoing research, monitoring, and synthesis related to the ecological effects of each issue.

    1988-08-01

    Two species of Schizotrypanum, T. (S.) dionisii and T. (S.) vespertilionis, were identified from British bats. Laboratory studies on stocks of isolated trypanosomes from 5 species of bat (Pipistrellus pipistrellus, Nyctalus leisleri, N. noctula, Eptesicus serotinus and Myotis brandti) indicated that the predominant species was T. d. dionisii. Collections and dissection of the bat bug Cimex pipistrelli from bat roosts revealed flagellate infection in a total of 12 out of 20 bugs; 7 of these bugs had metacyclic trypanosomes present. C. pipistrelli and the human bed bug, C. lectularius were reared in the laboratory and allowed to feed on wild-caught bats known to be infected with T. d. dionisii. Development occurred in both species of Cimex. Cimex spp. could be used to detect subpatent Schizotrypanum infections by xenodiagnosis. This technique was used to test the parasitological status of bats collected in the wild or reared in captivity. On a single occasion an apparent transmission of T. d. dionisii to an uninfected (by xenodiagnosis) laboratory reared bat was achieved. A stock of Schizotrypanum isolated from a wild-caught C. pipistrelli collected in a N. leisteri roost was identified by DNA buoyant density centrifugation as T. (S.) vespertilionis. A P. pipistrellus known to be infected with T. d. dionisii was found to have cyst-like structures in thoracic skeletal muscle containing amastigotes. The study provided the strongest evidence yet that C. pipistrelli is the vector of Schizotrypanum in British bats. PMID:3174237

  8. Understanding British addiction statistics.

    PubMed

    Johnson, B D

    1975-01-01

    The statistical data issued by the Home Office and Department of Health and Social Security are quite detailed and generally valid measures of hard core addiction in Great Britain (Judson, 1973). Since 1968, the main basis of these high quality British statistics is the routine reports filed by Drug Treatment Centres. The well-trained, experienced staff of these clinics make knowledgeable dicsions about a cleint's addiction, efficiently regulate dosage, and otherwise exert some degree of control over addicts (Judson, 1973; Johnson, 1974). The co-operation of police, courts, prison physicians, and general practitioners is also valuable in collecting data on drug addiction and convictions. Information presented in the tables above indicates that a rising problem of herion addiction between 1962 and 1967 were arrested by the introduction of the treatment clinics in 1968. Further, legally maintained heroin addiction has been reduced by almost one-third since 1968, since many herion addicts have been transferred to injectable methadone. The decline in herion prescribing and the relatively steady number of narcotics addicts has apparently occurred in the face of a continuing, and perhaps increasing, demand for heroin and other opiates. With few exceptions of a minor nature analysis of various tables suggests that the official statistics are internally consistent. There are apparently few "hidden" addicts, since few unknown addicts die of overdoses or are arrested by police (Lewis, 1973), although Blumberg (1974) indicates that some unknown users may exist. In addition, may opitate usersnot officially notified are known by clinic doctors as friends of addicts receiving prescriptions (Judson, 1973; Home Office, 1974). In brief, offical British drug statistics seem to be generally valid and demonstrate that heroin and perhaps methadone addiction has been well contained by the treatment clinics. PMID:1039283

  19. British psychiatry and its discontents

    PubMed Central

    Cooper, Brian

    2010-01-01

    Summary Psychiatry in the UK is currently faced with serious difficulties arising from failure in recruiting British doctors and a high rate of early retirement from the specialty. To diagnose the underlying causes, account must be taken of government policies affecting the NHS in general and mental health services in particular. The latter include an excessive run-down of acute hospital beds, as well as projects aimed at changing the clinical role of psychiatrists and promoting mass treatment of milder mental disorders by non-medical personnel. Psychiatrists have reacted to these developments with anger and dismay, but have as yet reached no consensus with regard to either causal factors or appropriate response. Their uncertainty reflects the need for a firmer grasp of the historical background. Modern British psychiatry was effectively created and moulded as an integral part of the NHS. It flourished as long as the public service framework remained intact, but has suffered a decline since the whole structure began to buckle under the pressure of sustained political assaults. A clearer understanding of this vital connection would help to raise psychiatrists' morale and encourage them to establish common ground with medical colleagues and other healthcare professionals.

    1994-01-01

    The purpose of this study was to audit the outcome in terms of change in practice of the published research from one volume of the British Medical Journal. All original papers and short reports from one Volume 296 of the British Medical Journal (BMJ) 1988 were read and classified into theoretical only, practical and theoretical and practical. Those papers with any practical message were reviewed by one of a panel of specialists in the subject of the paper to assess if the recommendation made by the paper had become common clinical practice. The results show that most papers originated from teaching centres and research institutes in the UK. Only 8% of main papers and 6% of short reports had a solely practical application, although a further 18% and 22% had practical elements. The majority of the recommendations aimed at changing practice were of relevance to hospital specialists rather than general practitioners (GPs). Of the papers with any practical implications 48% (12% of the total) of main papers and 41% (11% of the total) of short reports were considered to be current practice. The reasons why the papers failed to change practice are discussed. In conclusion, the majority of the original research papers published in the BMJ in 1988 were of a theoretical nature and only about 20% of papers made recommendations for a change in practice. About 50% of the recommendations are now current practice. PMID:7837183

    We studied the mortality experience of all pilots who died in the province of British Columbia between 1950 and 1984, using proportional mortality ratios (PMR) and proportional cancer mortality ratios (PCMR). There were 341 deaths during that time in males whose usual occupation was listed as pilot. The PMR for aircraft accidents was significantly elevated (PMR = 3196, 95% C.I. 2810, 3634), and the PMR for atherosclerotic heart disease was significantly depressed (PMR = 47, 95% C.I. 30, 70). Although based on small numbers of deaths, and not statistically significant, elevated PCMRs were seen for cancers of the colon, brain, and nervous system, as well as for Hodgkin's disease. These findings suggest the need for further epidemiologic studies of commercial airline pilots. PMID:2031640

    Clark, Hilda M.

    1965-01-01

    Since the Second World War, Britain has established or rehabilitated medical schools in eight territories for which she has some responsibility, and, through the British Council, she is making medical library services available in many other countries. Official organizations and professional bodies provide abstract and review journals which enable medical men overseas to keep abreast of modern knowledge, while the Library Association Medical Section and the British National Book Centre have established flourishing exchange services, whose facilities are offered to medical libraries abroad. The most pressing need in developing countries at the present time is for professional medical librarians. Opportunities for training in Britain are open to librarians through at least six official sources besides the British Council and World Health Organization, but so far only two trainees have presented themselves on such grants. Less experienced librarians in the developing countries also need the continuing support of their senior colleagues overseas. PMID:14223737

  1. Ambient Noise Tomography of the British Isles

    NASA Astrophysics Data System (ADS)

    Nicolson, H. J.; Curtis, A.; Baptie, B.

    2009-12-01

    In recent years, surface wave tomography using empirical Green’s functions computed via the ambient noise interferometry method has become an established approach to lithospheric imaging problems. To date, ambient noise tomography has been successfully applied to seismometer arrays in the United States, Australia, Iceland, China, South Africa, Europe and the Tibetan Plateau. The basis of the ambient seismic interferometry method is that, by cross-correlating noise data between two seismic stations and stacking over a long enough time period, one can approximate the Green’s Function that would have been recorded at one of the stations if the other had actually been a source. Consequently, one of the main advantages of ambient noise interferometry is that traditional seismic sources such as earthquakes or ballistics are not required; therefore it is ideal for application to seismically quiescent areas such as the British Isles. The British Isles are an archipelago located adjacent to the Eurasian continental shelf in a typically intra-plate setting, formed by a complex amalgamation of several terranes. These range from Laurentian north of the Highland Boundary fault to Avalonian south of the Iapetus Suture and evidence of the regions turbulent geological past can be inferred from its lithospheric structure. Previous studies of the structure of the British Isles considered relatively few seismic stations and/or were limited to using offshore shots, quarry blasts or teleseismic earthquakes as seismic energy sources. We have applied the ambient noise tomography method to noise data recorded on approximately 100 broadband and short period seismometers, including many new stations, in the British Isles and mainland Europe. This dense coverage of the British Isles allows us to image the crust and upper mantle velocity structure with a horizontal resolution in the region of 100km across the North Sea and 30km in the mainland United Kingdom. Here we present the first

  3. The British Lower Palaeolithic of the early Middle Pleistocene

    NASA Astrophysics Data System (ADS)

    Hosfield, Robert

    2011-06-01

    The archaeology of Britain during the early Middle Pleistocene (MIS 19-12) is represented by a number of key sites across eastern and southern England. These sites include Pakefield, Happisburgh 1, High Lodge, Warren Hill, Waverley Wood, Boxgrove, Kent's Cavern, and Westbury-sub-Mendip, alongside a 'background scatter' lithic record associated with the principal river systems (Bytham, pre-diversion Thames, and Solent) and raised beaches (Westbourne-Arundel). Hominin behaviour can be characterised in terms of: preferences for temperate or cool temperate climates and open/woodland mosaic habitats (indicated by mammalian fauna, mollusca, insects, and sediments); a biface-dominated material culture characterised by technological diversity, although with accompanying evidence for distinctive core and flake (Pakefield) and flake tool (High Lodge) assemblages; probable direct hunting-based subsistence strategies (with a focus upon large mammal fauna); and generally locally-focused spatial and landscape behaviours (principally indicated by raw material sources data), although with some evidence of dynamic, mobile and structured technological systems. The British data continues to support a 'modified short chronology' to the north of the Alps and the Pyrenees, with highly sporadic evidence for a hominin presence prior to 500-600 ka, although the ages of key assemblages are subject to ongoing debates regarding the chronology of the Bytham river terraces and the early Middle Pleistocene glaciations of East Anglia.

    PubMed

    Berch, Shannon M; Bonito, Gregory

    2016-08-01

    To improve baseline data for the developing truffle industry in British Columbia, we compiled existing Tuber species sequences from published and unpublished studies and generated new ITS sequences for truffles belonging to Tuber collected in the province. In doing so, we obtained evidence that 13 species of Tuber occur in the province, including six introduced and seven native species, two of which are putative undescribed species. Of the native species, the Tuber anniae species complex is widely distributed in the province while Tuber beyerlei appears to be much more restricted in distribution. Four of the introduced species have commercial value (Tuber melanosporum, Tuber aestivum, Tuber brumale, and Tuber borchii) as do two of the native species (Tuber gibbosum and Tuber oregonense). Focused sampling on likely tree hosts, both hardwood and Pinaceae species, as well as in currently unexplored parts of the province seems likely to expand our knowledge of the diversity and distribution of Tuber species in British Columbia.

  7. Accidental Deaths Among British Columbia Indians

    PubMed Central

    Schmitt, N.; Hole, L. W.; Barclay, W. S.

    1966-01-01

    A statistical and epidemiological review of British Columbia native Indian and non-Indian mortality revealed that accidents were the leading cause of death among Indians but ranked only fourth among non-Indians. Comparison of accidental death rates by age and sex showed that, without exception, the rates among Indians were considerably higher than the corressponding rates for non-Indians. While the Indians represented some 2% of the total population of British Columbia, they accounted for over 10% of the total accident fatalities, 29% of drownings, and 21% of fatal burns. Socioeconomic, environmental and psychosocial factors and excessive drinking are considered the chief causes responsible for this rather unusual epidemiological phenomenon. This study revealed certain hazardous conditions which are specific to the Indian's present way of life. In the authors' opinion the recognition of these specific hazards is imperative for the planning of effective preventive campaigns. PMID:5902238

    1996-12-31

    British Steel has four integrated steel works, i.e., Llanwern, Port Talbot, Scunthorpe, Teesside, with a total of ten blast furnaces, nine of which are currently operating. The furnaces range in size from the 14 meters (45 feet 11 inches) hearth diameter Redcar No. 1 furnace at Teesside (a single furnace works) to the 8.33 meters (27 feet 4 inches) hearth Queen Mary and Queen Bess furnaces at Schunthorpe, with a total of four furnaces at that works. All have injection systems installed, those at Scunthorpe being equipped with granular coal injection and all others currently working with oil injection. The driving force behind the development of blast furnace injection has been as a means for introducing reducing agents (British Steel now refers to coke plus hydrocarbon injectants as total reductants) into the process as a part substitute/supplement for top charged coke and the technology is still being developed and used for that purpose. By utilizing practical experience and observing the work of others, British Steel has been assessing blast furnace injection technology experimentally for purposes other than the introduction of reducing agents.

  9. Sustainable development in British land use regulation

    SciTech Connect

    Basiago, A.D.

    1995-12-01

    Sustainable development is a new international theory of development founded on principles of futurity, environment, equity and participation. It is the legacy of twenty years of international environmental law that has established a doctrine of global trusteeship. Sustainable development has entered British land use regulation through the Maastricth Treaty; the EU`s Fifth Environmental Action Program; as well as the British government`s Planning Policy Guidance notes on land use principles, local plans, transport and historic preservation, and its white papers. The Earth Summit accord Agenda 21 is a blueprint on how to make development socially, economically and environmentally sustainable. Under its terms, Britain has prepared a national sustainable development strategy for the UN`s Commission on Sustainable Development. It features Local Agenda 21 strategies in which local authorities develop policies for sustainable development and establish partnerships with other sectors. In this paper, the Local Agenda 21 strategies of seven local authorities are evaluated according to the paradigm introduced in Agenda 21 and elaborated by Kahn that describes sustainable development as a dynamic system of integrated and interlinked economic, social and environmental sustainability. The author concludes that sustainable development in British land use regulation is guided by notions of economic development, social justice and environmental planning and not by the dynamic, integrated model of Agenda 21. 46 refs., 3 figs.

    faculty and students from the University of the Fraser Valley have conducted the time series sampling of water chemistry of the Fraser River at Fort Langley and five Fraser Valley tributaries as a member of the Global Rivers Observatory (GRO, www.globalrivers.org) organized by Woods Hole Oceanographic Institution and Woods Hole Research Center. Clayburn Creek and Willband Creek in Abbotsford, British Columbiahave been part of this project and have been sampled for nutrient and major ion concentrations and parameters such as water temperature, dissolved oxygen, conductivity, pH and turbidity. This watershed is being threatened by increasing anthropogenic activity (agricultural, industrial and residential development) that may threaten the salmon that spawn in this watershed. Documenting the change in the water chemistry in this watershed as the seasons progress from a dry summer to a wet fall will yield a greater understanding of our impact on this watershed and may assist our attempts to protect this watershed.

    1994-12-31

    Between February 29 and March 15, 1992, 30 trumpeter swans (Cygnus buccinator) were found dead or debilitated at Judson Lake in the lower Fraser valley of southwestern British Columbia. Autopsies of 17 swans revealed the cause of death as lead poisoning from ingestion of lead shot. Lead shot was present in the gizzards of 20 of the swans examined; average number of pellets was nine. Lead was detected in all liver and kidney samples tested. Liver lead concentrations ranged from 21 to 166 ug/g dry wt., with a mean of 64 ug/g d.w. Lead levels in kidneys ranged from 212 to 303 ug/g d.w., with a mean of 120 ug/g d.w. The amount of lead shot in the gizzard was not well correlated with lead levels in the liver and kidney; correlation coefficients of 0.20 and 0.54 were attained, respectively. High iron levels were noted in livers. Other elements (Se, Co, Zn, Mn, Cd, Ca, Mg) were not elevated in either the liver or kidney. The incident prompted the authors to review lead poisoning of swans in British Columbia; data from published and unpublished sources are analyzed, presented and discussed.

    PubMed

    Kyriakides, Christopher; Virdee, Satnam

    2003-11-01

    This study explores the dynamics of racism, specifically its generation and reproduction as an ideology, and its role in affecting the reception and occupational location of migrant medical labour in Britain. It is argued that the treatment of 'overseas doctors' in Britain draws on a complex interplay between racism and nationalism underpinned by the historical construction of 'welfarism' as a moral legitimator of 'Britishness'. Through an exploration of internal and external immigration controls introduced with the aim of regulating migrant labour, we demonstrate how British social policy and elite discourses of 'race' combine to construct moral prescriptions of threat such that migrants and British-born 'non-whites' entering the British medical profession are forced to negotiate 'saviour/pariah' ascriptions indicative of discriminatory but contradictory processes specific to the operation of the British National Health Service as a normative institution.

    2014-01-01

    GM2 gangliosidosis (Tay-Sachs disease) was diagnosed in 6- to 8-month-old pedigree Jacob lambs from two unrelated flocks presenting clinically with progressive neurological dysfunction of 10 day's to 8 week's duration. Clinical signs included hindlimb ataxia and weakness, recumbency and proprioceptive defects. Histopathological examination of the nervous system identified extensive neuronal cytoplasmic accumulation of material that stained with periodic acid--Schiff and Luxol fast blue. Electron microscopy identified membranous cytoplasmic bodies within the nervous system. Serum biochemistry detected a marked decrease in hexosaminidase A activity in the one lamb tested, when compared with the concentration in age matched controls and genetic analysis identified a mutation in the sheep hexa allele G444R consistent with Tay-Sachs disease in Jacob sheep in North America. The identification of Tay-Sachs disease in British Jacob sheep supports previous evidence that the mutation in North American Jacob sheep originated from imported UK stock. PMID:24309906

    1986-12-01

    Otters (subfamily Lutrinae), at the top of the food chain and feeding largely on fish, are likely to be especially vulnerable to the effects of bioaccumulating pollutants, while their aquatic habitat is often a sink for such chemicals derived from agricultural, industrial and domestic sources. The European otter (Lutra lutra) has shown substantial declines through much of its range over the past 30 years, which have been attributed to pollution by organochlorines. There are few published data on metals in tissues of European otters and these refer only to mercury. The present paper reports on burdens of mercury, cadmium and lead in tissues of a sample of British otters collected between 1982 and 1984.

    Analysis of the makeup and contributions of the British contingents to the first two Solvay Councils can elucidate the character of British mathematical physics and its internal dynamics at a critical time in its development. The paper provides this analysis, outlines the process of selection of the participants, parses the meaning of "international" in the Solvay context, and offers an explanation of the differential attendance of the British at the two Councils. Most of those invited to the first refused whereas all but one of those invited to the second accepted. The unusual social and scientific views of Ernest Solvay help to explain this divergence.

    Multi-decadal records of monthly sea surface temperature (SST) and sea surface salinity (SSS) collected at a set of lighthouse stations are used to examine climatic variability and trends in the coastal waters of British Columbia. Particular attention is given to relations between the water property anomalies and variability in coastal freshwater discharge and alongshore wind stress. Within the Strait of Georgia, SSS anomalies are closely related to Fraser River discharge anomalies. Along the Pacific coast, anomalies in alongshore wind stress and freshwater runoff have the characteristics of white noise processes. A cross-correlation analysis demonstrates that SST and SSS variability along the open west coast is consistent with the response of a first-order autoregressive process driven by anomalous alongshore wind stress and coastal freshwater discharge, respectively. Thus climatic variability of SST and SSS along the Pacific coast of British Columbia occurs, in part, through the integration of noisy atmospheric forcing and coastal precipitation. Seasonal correlations show that SST is strongly related to wind stress during winter and fall. Conversely, SSS is relatively weakly related to the alongshore wind during spring, suggesting that variability in upwelling makes only a modest contribution to variability of SSS in the nearshore environment. Consistent with previous studies, secular trends indicate long-term warming and freshening of the coastal ocean at most stations. It is shown that long-term SST trends can be obscured by the pronounced climatic variability of these waters, requiring that time series extend for several decades to be reliably detected.

    Pavilion Lake is a slightly alkaline, freshwater lake located in British Columbia, Canada (50°51'N, 121°44'W). It is known for unusual organosedimentary structures, called microbialites that are found along the lake basin. These deposits are complex associations of fossilized microbial communities and detrital- or chemical-sedimentary rocks. During the summer, a sediment sample was collected from near the lake's shore, approximately 25–50 cm below the water surface. Magnetotactic bacteria (MTB) were isolated from this sample using a simple magnetic enrichment protocol. The MTB isolated from Pavilion Lake belonged to the Alphaproteobacteria class as determined by nucleotide sequences of 16S rRNA genes. Transmission electron microscopy (TEM) revealed that the bacteria were spirillum-shaped and contained a single chain of cuboctahedral-shaped magnetite (Fe3O4) crystals that were approximately 40 nm in diameter. This discovery of MTB in Pavilion Lake offers an opportunity to better understand the diversity of MTB habitats, the geobiological function of MTB in unique freshwater ecosystems, and search for magnetofossils contained within the lake's microbialites.

  20. The Planetary Consciousness of British Travel Writers

    Henry, H.

    2013-04-01

    Global travel, advanced in the early 20th century by trains, automobiles, and airplanes, transformed modernist thought and experience. Stephen Kern has commented that in the modern period “a series of sweeping changes in technology and culture created distinctive new modes of thinking about and experiencing of time and space. Technological innovations including the telephone, wireless telegraph, x-ray, cinema, bicycle, automobile, and airplane established the material foundation for this reorientation.” (1983, pp. 1-2). Emerging travel technologies not only hurled passengers through multiple time zones in a day but also brought to the fore a global awareness regarding Earth as a globe in space and one's position on it. As early as 1909, while traveling in Florence, Virginia Woolf had noted in her diary, “It is strange how one begins to hold a globe in one's head: I can travel from Florence to Fitzroy Square on solid land all the time” (1984, p. 399). This paper traces the ways modernist British travel writers challenged England's geographical and geopolitical imagination at the turn of the 20th century through their travel narratives.

  1. ASPIRE - the first British student rocket programme

    NASA Astrophysics Data System (ADS)

    Baker, Adam M.; Murray, J.; Osborne, R.; Macfarlane, J.

    ASPIRE is the first British programme aiming to create and develop a small scale, hybrid engine powered launch vehicle. The project is also unique because it is a wholly amateur effort, volunteer team members having little or no professional experience in launch vehicle design, manufacture and operations; and being a mix of students and young professionals. Participants have the opportunity to develop their experience in the engineering/scientific, operational and management areas which ASPIRE encompasses. This experience will then be validated through the launching of a series of test vehicles, culminating in a demonstration of the orbital insertion of a payload by the year 2000. ASPIRE aims to eventually return an independent orbital launch capability to Britain, for the first time since 1971. This paper outlines the technical details of the ASPIRE rockets, including: airframe design and manufacture, hybrid motor design and testing, avionics development, guidance and recovery techniques, range safety practise and marketing and fund-raising. It will also cover the organisation and ethos of the programme in general. A timeline for the ASPIRE programme will be detailed, from the original ASPIRE 1 construction and launch in 1991/1992, evolving through the current series of ASPIRE Development Vehicles (ADVs), to ASPIRE 2 and 3, where the hybrid motor and other engineering subsystems are to be integrated on an increasing scale. The proposed union of an ASPIRE 3 vehicle with an Australian AUSROC launcher to achieve the 2000 orbital goal will also be covered.

  3. Utopianism in the British evolutionary synthesis.

    Esposito, Maurizio

    2011-03-01

    In this paper I propose a new interpretation of the British evolutionary synthesis. The synthetic work of J. B. S. Haldane, R. A. Fisher and J. S. Huxley was characterized by both an integration of Mendelism and Darwinism and the unification of different biological subdisciplines within a coherent framework. But it must also be seen as a bold and synthetic Darwinian program in which the biosciences served as a utopian blueprint for the progress of civilization. Describing the futuristic visions of these three scientists in their synthetic heydays, I show that, despite a number of important divergences, their biopolitical ideals could be biased toward a controlled and regimented utopian society. Their common ideals entailed a social order where liberal and democratic principles were partially or totally suspended in favor of bioscientific control and planning for the future. Finally, I will argue that the original redefinition of Darwinism that modern synthesizers proposed is a significant historical example of how Darwinism has been used and adapted in different contexts. The lesson I draw from this account is a venerable one: that, whenever we wish to define Darwinism, we need to recognize not only its scientific content and achievements but expose the other traditions and ideologies it may have supported.

    Although it is over 30 years since an excess of bladder cancer was first identified in British rubber workers, the fear has persisted that this hazard could still be affecting men working in the industry today. Furthermore, suspicions have also arisen that other and hitherto unsuspected excesses of cancer might be occurring. For these reasons 33 815 men, who first started work in the industry between 1 January 1946 and 31 December 1960, have been followed up to 31 December 1975 to ascertain the number of deaths attributable to malignant disease and to compare these with the expected number calculated from the published mortality rates applicable to the male population of England and Wales and Scotland. The findings confirm the absence of any excess mortality from bladder cancer among men entering the industry after 1 January 1951 (the presumed bladder carcinogens were withdrawn from production processes in July 1949), but they confirm also a statistically significant excess of both lung and stomach cancer mortality. A small excess of oesophageal cancer was also observed in both the tyre and general rubber goods manufacturing sectors. American reports of an excess of leukaemia among rubber workers receive only limited support from the present study, where a small numerical excess of deaths from leukaemia is not statistically significant. A special feature of the study is the adoption of an analytical method that permits taking into account the long latent period of induction of occupational cancer. PMID:7093147

    1994-01-01

    Aspergillus nidulans is a holomorphic fungus, capable of producing both meiotically and mitotically derived spores. Meiosis may be an evolutionary relic in this species because it is potentially capable of mitotic recombination and because most Aspergilli lack the ability to produce meiotic spores. We tested the null hypothesis that meiosis has been a major factor in the origin of strains of A. nidulans from Great Britain by estimating linkage disequilibrium among restriction fragment length polymorphisms. These strains belong to different heterokaryon compatibility groups and are thus incapable of undergoing mitotic recombination with one another, so any recombination evidenced by linkage equilibrium is assumed to be the result of meiosis. Eleven cosmid clones of known chromosomal origin were used to generate multilocus genotypes based on restriction-pattern differences for each heterokaryon compatibility group. Low levels of genetic variation and little linkage disequilibrium were found, indicating that the heterokaryon compatibility groups represent recently diverged lineages that arose via meiotic recombination. The null hypothesis that loci are independent could not be rejected. Additionally, low levels of electrophoretic karyotype variation were indicative of meiosis. We conclude that although A. nidulans probably propagates in a primarily clonal fashion, recombination events are frequent enough to disrupt the stable maintenance of clonal genotypes. We further conclude that the British heterokaryon compatibility groups arose via recombination and not through novel mutation. Images PMID:7907796

  11. The history of British gynaecological pathology.

    PubMed

    Young, Robert H

    2009-01-01

    The venerable tradition of British gynaecological pathology is honoured by brief comments on those who have pioneered work in this arena, using as the starting point the remarkable Scottish physician Dr Matthew Baillie who, with his uncles, the legendary William and John Hunter, can arguably be considered the founders of medicine in Great Britain. The impact of Baillie's great work 'The Morbid Anatomy of Some of the Most Important Parts of the Human Body' is noted. Because of the fame they achieved in working in other areas, the contributions to gynaecological pathology of Thomas Hodgkin and Richard Bright, particularly the former, are often overlooked and are noted herein as is a remarkable book on the ovary by Charles G. Ritchie, published in 1865. The middle years of the 19th century were notable because of the activities of pioneering surgeons such as Sir Spencer Wells and Lawson Tait which gradually led to a greater emphasis on pathologic examination of specimens removed at operation, as opposed to autopsy evaluation. The closing years of the 19th century and early years of the 20th century were dominated by five individuals, Alban Doran, John Bland-Sutton, Cuthbert Lockyer, Elizabeth Hurdon and John Hammond Teacher. Doran wrote an early study of tubal carcinoma and a book on that organ and the ovary. Bland-Sutton was a remarkably influential surgeon with a significant interest in pathology and also contributed a book on the ovary and fallopian tube as well as one of the early good papers on metastatic tumours to the ovary. Lockyer wrote an outstanding book on uterine fibroids and established, and funded, a museum at Charing Cross Hospital. Hurdon can be considered the first female gynaecological pathologist. She spent much of her active career in the United States working at Johns Hopkins Hospital. She co-authored a monumental book on the appendix, likely never to be equalled. Teacher worked in Glasgow for many years and was almost single-handedly responsible

    Faculty and students from the University of the Fraser Valley participate in the time series sampling of the Fraser River and Fraser River tributaries as part of the Global Rivers Observatory (GRO, www.globalrivers.org) which is coordinated by Woods Hole Oceanographic Institution and Woods Hole Research Center. Clayburn and Willband Creeks in Abbotsford, British Columbia are part of this project and are being threatened by increasing anthropogenic activity (agricultural, industrial and residential development) within the watershed. Undergraduate students from the Geography and Biology departments have been instructed in the sampling protocols and the collection of thw water chemistry data. Each student that has been involved in this sampling project will gain a greater understanding of the seasonal variation of the water chemistry of the Clayburn watershed. Through this involvement in this portion of the Global Rivers Observatory our students become more aware of the threats to our streams and the methods utilized to monitor water chemistry.

  13. Low Temperature Paleogene Thermal Evolution of the British Mountains using Apatite U-Th/He Dating, Northern Yukon, Canada

    The age and rate of exhumation of the British Mountains is tied to the timing of deformation in the Beaufort Sea, an active site for hydrocarbon exploration. This region contains a large portion of North America's oil and gas reserves. The British Mountains, the eastern extent of the Brooks Range in Alaska, include Paleogene structures that are the onshore portion of the Beaufort fold belt. In the Beaufort Sea, deformation is dominated by thin-skinned folding and thrusting of Paleocene to Oligocene sediments that is sourced from the British Mountains. Onshore, Paleogene deformation overprints multiple older structural events. The low temperature time history of the onshore Paleogene structures will be determined through U-Th/He dating of apatites (AHe). The results will contribute to better understanding of the timing of the maturation and migration of hydrocarbons in the Beaufort Sea. Previous work on the thermal history of northern Yukon and the North Slope of Alaska provides a regional framework for the region's low temperature-time history. These regional studies of the northern Yukon and Alaska yielded Paleocene to Eocene (60Ma - 40Ma) apatite fission track (AFT) cooling ages that progressively young to the north, consistent with geological evidence for northward propagating deformation. The British Mountains consist of Neoproterozoic to early Paleozoic marine sediments that are intruded by scattered Devonian plutons; both rock types will be included in the study. This study aims to improve the understanding of the Paleogene tectonic activity of the British Mountains and the deformation history of the Beaufort fold belt. The two data sets, existing AFT and new AHe results, will be both be included in the interpretation of the study area. We will present AHe data to better constrain the onshore exhumation and deformation rates at low temperatures (~60-90°C). A sampled transect through the British mountains, along the Firth River valley will provide good

    Recently a number of new and/or updated sources for estimates of vertical land movements for the British Isles have become available allowing the relative and average changes in sea levels for this region to be revisited. The geodetic data set stems from a combination of re-processed continuous Global Positioning System (GPS) measurements from stations in the British Isles and from a global reference frame network, and absolute gravity (AG) measurements from two stations in the British Isles. The geologic data set of late Holocene sea level indicators has recently been updated, now applying corrections for the 20th century sea level rise, syphoning effect and late Holocene global ice melt, and expanded to Northern Ireland and Ireland. Several new model predictions of the glacial isostatic adjustment (GIA) process active in this region form the modelling data set of vertical land movements for the British Isles. Correcting the updated revised local reference (RLR) trends from the Permanent Service for Mean Sea Level (PSMSL) with these vertical land movement data sets, regional and averaged changes in sea levels around the British Isles have been investigated. Special focus is thereby also given to the coastal areas that have recently been identified within the UK Climate Projections 2009.

    The most developed and widely used fixed bed pressure gasification systems are based on the Lurgi Gasification Process. The British Gas/Lurgi Slagging Gasifier results from the joing together of British Gas Corporation and Lurgi Company technology. The British Gas Slagging Gasification technology offers significant advantages over dry bottom Lurgi and other fixed bed gasification systems. The slagging gasifier has more advantages than disadvantages when compared with entrained flow gasifiers and these advantages are sufficient to give it an economic advnatage in most process situations. The processing of crude Slagging Gasifier gas and the multifarious uses of the resulting clean gas in the chemicals, power generation and fuel gas fields are described. The environmental impact of the process is also discussed and plans for commercialization are considered. 21 refs.

  16. On the impartiality of early British clinical trials.

    PubMed

    Teira, David

    2013-09-01

    Did the impartiality of clinical trials play any role in their acceptance as regulatory standards for the safety and efficacy of drugs? According to the standard account of early British trials in the 1930s and 1940s, their impartiality was just rhetorical: the public demanded fair tests and statistical devices such as randomization created an appearance of neutrality. In fact, the design of the experiment was difficult to understand and the British authorities took advantage of it to promote their own particular interests. I claim that this account is based on a poorly defined concept of experimental fairness (derived from T. Porter's ideas). I present an alternative approach in which a test would be impartial if it incorporates warrants of non-manipulability. With this concept, I reconstruct the history of British trials showing that they were indeed fair and this fairness played a role in their acceptance as regulatory yardsticks. PMID:23743210

    The Munro-Adams Love Attitude Scale was administered to 133 randomly chosen final-year undergraduate White South African and British university students in this examination of their attitudes toward love, courtship, and marriage in relation to the observation that, although South African tertiary educational institutions exist within the authoritarian and restrictive culture of apartheid, they nevertheless are modeled on the British educational system, which has its roots deeply embedded within a politically democratic context. Results indicated that the South African sample's endorsement of the love attitude items was weaker, except for those pertaining to the power of love, than that of their British counterparts. In addition, the South African scores were lower than those previously reported in other similar cross-cultural research, and there was a differential ranking of the three love styles by the male and female subjects.

    Decision Support Aids (DSAs) have been widely used throughout industry and one (known as Table 7) is available to support British Army Medical Officers (MOs) grade soldiers against the Joint Medical Employment Standards. It is unknown how useful this DSA is in practice. An electronic questionnaire was distributed to British Army MOs working within Defence Primary Care facilities enquiring about MOs views on the usefulness of the DSA. Although the response rate was low, informative data were obtained. Between a half and a third of respondents felt that their judgement was affected in the application of the grading system when there were career implications to the grading MOs felt that the DSA allowed subjectivity in the grading. The results of this research suggest that although minor changes to Table 7 may improve service provision, an improvement in training in the application of Table 7 would be of greater benefit to the quality of occupational health service provision in the British Army.

    Bonneville Power Administration (BPA) is responding to the need to prevent the extinction of the Kootenai River white sturgeon (Acipenser transmontanus) between Libby Dam in Montana and Corra Linn Dam in British Columbia. Construction and operation of Libby Dam altered the natural flow of the Kootenai River, especially the normal May-to-July flows needed for natural reproduction and recruitment. It also affected the river`s biological productivity and the quality of spawning and rearing habitat. As part of its responsibilities under the Northwest Power Act (Pacific Northwest Electric Power Planning and Conservation Act of 1980), BPA must mitigate for losses of fish and wildlife (including related spawning grounds and habitat) that are attributable to power production at federal hydroelectric dams on the Columbia River and its tributaries.

  20. Towards Space Tourism - The Challenge for British Space Policy

    NASA Astrophysics Data System (ADS)

    Collins, P.

    In recent years it has become increasingly widely accepted, including within NASA, that the largest commercial opportunity in space is the development of passenger space travel, or `space tourism'. However, to date, the British government has provided no support whatever for work in this field. In 2000 the parliamentary Trade and Industry Select Committee criticized this unsatisfactory situation, but their comments have been disregarded to date. This paper reviews the current situation and discusses measures that must be implemented in order for British taxpayers to obtain the greatest economic benefit from the government's space expenditure.

    From 1983 to 1986, John Moore served in the Thatcher government in Britain, launching that country's privatization program. In "British Privatization--Taking Capitalism to the People, " he describes the thinking behind privatization, the objections raised against it, and the actual measures taken to implement it. With privatization, corporate performance has improved and the government has been able to focus on regulation, not ownership. But in the end, says Moore, the greatest success of British privatization was that it transformed the public's attitude toward ownership and economic responsibility. PMID:10119711

    We exploit migration patterns from the UK to Australia and the US to investigate whether a person's decision to smoke is determined by culture. For each country, we use retrospective data to describe individual smoking trajectories over the life-course. For the UK, we use these trajectories to measure culture by cohort and cohort-age, and more accurately relative to the extant literature. Our proxy predicts smoking participation of second-generation British immigrants but not that of non-British immigrants and natives. Researchers can apply our strategy to estimate culture effects on other outcomes when retrospective or longitudinal data are available. PMID:25620826

    The University of the Fraser Valley has undertaken the time series sampling of water chemistry of the Fraser River at Fort Langley, British Columbia and five Fraser Valley tributary creeks as a member of the Global Rivers Observatory (GRO, www.globalrivers.org) which is coordinated by Woods Hole Oceanographic Institutionand Woods Hole Research Center. Kanaka Creek (Maple Ridge), Silverdale Creek (Mission), Clayburn Creek, Willband Creek and Nathan Creek (Abbotsford) have been sampled as part of the GRO. The creeks have been sampled for nutrient concentrations (silicate, phosphate, nitrate/nitrite, and ammonium), major ions and water chemistry parameters, such as dissolved oxygen, temperature, conductivity, pH, and turbidity monthly over the past four years. Each of these salmon bearing creeks is being threatened by anthropogenic activity (agricultural, industrial and residential development) that is occurring in the watersheds. Nathan and Willband Creeks are being threatened by agricultural activity, while Kanaka, Clayburn and Silverdale Creeks are being threatened by residential developments. Understanding these changes and their seasonal variations is crucial in assisting in protecting the natural habitat of these watersheds and streams.

  5. The O and H stable isotope composition of freshwaters in the British Isles. 2. Surface waters and groundwater

    NASA Astrophysics Data System (ADS)

    Darling, W. G.; Bath, A. H.; Talbot, J. C.

    The utility of stable isotopes as tracers of the water molecule has a long pedigree. The study reported here is part of an attempt to establish a comprehensive isotopic "baseline" for the British Isles as background data for a range of applications. Part 1 of this study (Darling and Talbot, 2003) considered the isotopic composition of rainfall in Britain and Ireland. The present paper is concerned with the composition of surface waters and groundwater. In isotopic terms, surface waters (other than some upland streams) are poorly characterised in the British Isles; their potential variability has yet to be widely used as an aid in hydrological research. In what may be the first study of a major British river, a monthly isotopic record of the upper River Thames during 1998 was obtained. This shows high damping of the isotopic variation compared to that in rainfall over most of the year, though significant fluctuations were seen for the autumn months. Smaller rivers such as the Stour and Darent show a more subdued response to the balance between runoff and baseflow. The relationship between the isotopic composition of rainfall and groundwater is also considered. From a limited database, it appears that whereas Chalk groundwater is a representative mixture of weighted average annual rainfall, for Triassic sandstone groundwater there is a seasonal selection of rainfall biased towards isotopically-depleted winter recharge. This may be primarily the result of physical differences between the infiltration characteristics of rock types, though other factors (vegetation, glacial history) could be involved. In the main, however, groundwaters appear to be representative of bulk rainfall within an error band of 0.5‰ δ18O. Contour maps of the δ18O and δ2H content of recent groundwaters in the British Isles show a fundamental SW-NE depletion effect modified by topography. The range of measured values, while much smaller than those for rainfall, still covers some ‰ for δ18

    The Wigwam River bull trout (Salvelinus confluentus) and fish habitat monitoring program is a trans-boundary initiative implemented by the British Columbia Ministry of Environment, Lands and Parks (MOE), in cooperation with Bonneville Power Administration (BPA). The Wigwam River is an important fisheries stream located in southeastern British Columbia that supports healthy populations of both bull trout and Westslope cutthroat trout (Figure 1.1). This river has been characterized as the single most important bull trout spawning stream in the Kootenay Region (Baxter and Westover 2000, Cope 1998). In addition, the Wigwam River supports some of the largest Westslope cutthroat trout (Oncorhynchus clarki lewisi) in the Kootenay Region. These fish are highly sought after by anglers (Westover 1999a, 1999b). Bull trout populations have declined in many areas of their range within Montana and throughout the northwest including British Columbia. Bull trout were blue listed as vulnerable in British Columbia by the B.C. Conservation Data Center (Cannings 1993) and although there are many healthy populations of bull trout in the East Kootenays they remain a species of special concern. Bull trout in the United States portion of the Columbia River were listed as threatened in 1998 under the Endangered Species Act by the U.S. Fish and Wildlife Service. The upper Kootenay River is within the Kootenai sub-basin of the Mountain Columbia Province, one of the eleven Eco-provinces that make up the Columbia River Basin. MOE applied for and received funding from BPA to assess and monitor the status of wild, native stocks of bull trout in tributaries to Lake Koocanusa (Libby Reservoir) and the upper Kootenay River. This task is one of many that was undertaken to ''Monitor and Protect Bull Trout for Koocanusa Reservoir'' (BPA Project Number 2000-04-00).

  7. Wigwam River Juvenile Bull Trout and Fish Habitat Monitoring Program : 2002 Data Report.

    SciTech Connect

    Cope, R.S.

    2003-03-01

    The Wigwam River bull trout (Salvelinus confluentus) and fish habitat monitoring program is a trans-boundary initiative implemented by the British Columbia Ministry of Water, Land, and Air Protection (MWLAP), in cooperation with Bonneville Power Administration (BPA). The Wigwam River is an important fisheries stream located in southeastern British Columbia that supports healthy populations of both bull trout and Westslope cutthroat trout (Figure 1). This river has been characterized as the single most important bull trout spawning stream in the Kootenay Region (Baxter and Westover 2000, Cope 1998). In addition, the Wigwam River supports some of the largest Westslope cutthroat trout (Oncorhynchus clarki lewisi) in the Kootenay Region. These fish are highly sought after by anglers (Westover 1999a, 1999b). Bull trout populations have declined in many areas of their range within Montana and throughout the northwest including British Columbia. Bull trout were blue listed as vulnerable in British Columbia by the B.C. Conservation Data Center (Cannings 1993) and although there are many healthy populations of bull trout in the East Kootenay they remain a species of special concern. Bull trout in the United States portion of the Columbia River were listed as threatened in 1998 under the Endangered Species Act by the U.S. Fish and Wildlife Service. The upper Kootenay River is within the Kootenai sub-basin of the Mountain Columbia Province, one of the eleven Eco-provinces that make up the Columbia River Basin.

  13. Hepatitis C virus infection in the asymptomatic British blood donor.

    1995-01-01

    Blood donor screening for hepatitis C virus (HCV) antibodies is now routine. Most blood transfusion services recommend that seropositive donors are referred for further investigation. Southern European studies suggest that many asymptomatic seropositive donors have clinically significant liver disease. Seropositive donors in areas of high prevalence may not, however, be representative of British donors. We have prospectively examined the prevalence and severity of HCV infection in a British volunteer blood donor population. During a 14 month period, only 0.35% (999/287,332) of all donors in the West Midlands were anti-HCV (screening assay) positive. Only 5% (52/999) of these were confirmed true seropositive. Nearly 80% (41/52) of seropositive donors were referred to the Queen Elizabeth Hospital Liver Unit for further investigation. Most underwent complete investigation, including liver biopsy. Forty of forty-one donors had biochemical, histological, or virological evidence of persistent viral infection. Histological changes were generally mild and none was cirrhotic. Covertly infected patients had less severe disease than those with an overt risk factor for HCV exposure. In the British Midlands, the prevalence of blood donor seropositivity is low. In contrast with seropositive Southern European donors, the British donor is more likely to belong to an at-risk group for parenteral exposure and is less likely to have severe histological changes. This study highlights the importance of developing locally relevant guidelines for the counselling and investigation of anti-HCV-positive blood donors. PMID:7493294

  11. A comparison of physical activity and sedentary behaviour in 9–11 year old British Pakistani and White British girls: a mixed methods study

    PubMed Central

    2014-01-01

    Background Previous studies suggest that British children of South Asian origin are less active and more sedentary than White British children. However, little is known about the behaviours underlying low activity levels, nor the familial contexts of active and sedentary behaviours in these groups. Our aim was to test hypotheses about differences between British Pakistani and White British girls using accelerometry and self-reports of key active and sedentary behaviours, and to obtain an understanding of factors affecting these behaviours using parental interviews. Methods Participants were 145 girls (70 White British and 75 British Pakistani) aged 9–11 years and parents of 19 of the girls. Accelerometry data were collected over 4 days and girls provided 24-hour physical activity interviews on 3 of these days. Multilevel linear regression models and generalised linear mixed models tested for ethnic differences in activity, sedentary time, and behaviours. Semi-structured interviews were conducted with parents. Results Compared to White British girls, British Pakistani girls accumulated 102 (95% CI 59, 145) fewer counts per minute and 14 minutes (95% CI 8, 20) less time in moderate to vigorous physical activity per day. British Pakistani girls spent more time (28 minutes per day, 95% CI 14, 42) sedentary. Fewer British Pakistani than White British girls reported participation in organised sports and exercise (OR 0.22 95% CI 0.08, 0.64) or in outdoor play (OR 0.42 95% CI 0.20, 0.91). Fewer British Pakistani girls travelled actively to school (OR 0.26 95% CI 0.10, 0.71). There was no significant difference in reported screen time (OR 0.88 95% CI 0.45, 1.73). Parental interviews suggested that structural constraints (e.g. busy family schedules) and parental concerns about safety were important influences on activity levels. Conclusions British Pakistani girls were less active than White British girls and were less likely to participate in key active behaviours

    The last two decades have witnessed some of the most severe droughts experienced within living memory in the UK, but have these droughts really been exceptional? Relatively few instrumental river flow, groundwater or reservoir series extend beyond 50 years in length, with few precipitation series currently available extending over 100 years. These relatively short series present considerable challenges in determining current and future drought risk, with the results affecting society and the economy. This study uses long instrumental precipitation series coupled with the SPI and scPDSi drought indices to reconstruct drought histories from different parts of the British Isles. Existing long precipitation series have been reassessed and several new precipitation series reconstructed (e.g. Carlisle 1757), with eight series now over 200 years in length, and a further thirteen over 150 years, with further sites currently being developed (e.g. Norwich, 1749-; Exeter, 1724-). This study will focuses on the eight longest series, with shorter series used to help explore spatial and temporal variability across British Isles. We show how historical series have improved understanding of severe droughts, by examining past spatial and temporal variability and exploring the climatic drivers responsible. It shows that recent well documented droughts (e.g. 1976; 1996 and 2010) which have shaped both public and water resource managers' perceptions of risk, have historically been exceeded in both severity (e.g. 1781) and duration (e.g. 1798-1810); with the largest droughts often transcending single catchments and affecting regions. Recent droughts are not exceptional when considered within a multi-centennial timescale, with improved understanding of historical events raising concerns in contemporary water resource management.

    Surveys have confirmed the survival of both the giant Columbia River spire snail Fluminicola columbiana and the great Columbia River limpet Fisherola nuttalli in the Hanford Reach of the Columbia River, Washington State, as well as other sites in Washington, Oregon, and Idaho. A review of historical collection records suggests that both species exist in still other sites of the Columbia River Basin. At present, there is insufficient information to allow adequate appraisal of either species relative to possible federal or state listing as endangered or threatened species. The results of our studies suggest that additional undiscovered populations of both species exist. There is a relatively good chance that pristine habitat required by spire snails and limpets remains in 37 streams or portions of streams in Washington, Oregon, Idaho, and Montana (British Columbia was considered outside the project scope). For a thorough survey, visits to more than 600 sites will be required. 20 refs., 5 figs., 7 tabs.

    The 2007 Chehalis Lake tsunami in the southern Coast Mountains of British Columbia is one of the most comprehensively described landslide-generated tsunamis in the world. We use field observations and remotely sensed data collected during the two years following the tsunami to characterize its geomorphic impact and propose a suite of geomorphic features characteristic of tsunamis generated by subaerial landslides. On December 4, 2007, a highly fragmented 3 Mm3 rockslide entered the north end of Chehalis Lake and generated a tsunami that drastically altered much of the shore of the 8.5-km-long lake, with local run-up exceeding 35 m. The tsunami continued as a surge down lower Chehalis River, at the south end of the lake. We characterized geomorphic features produced by the tsunami by collecting multi-scale data, starting immediately after the event. Data included reconnaissance helicopter and ground observations, low-altitude aerial digital photography and aerial LiDAR survey, detailed GPS-controlled field traverses, and an underwater survey using side-scan sonar and swath bathymetric sounding. The impact of the tsunami was greatest on low-gradient shores and the shoreline nearest the landslide. Erosional features include wave-cut scarps, soil erosion, and complete removal of forest, leaving sharp trimlines. Debris transported by the tsunami stripped bark from standing trees, left impact marks on them, and embedded gravel in them. Depositional features include imbricated cobbles and boulders, ripples in sand and gravel, pebble lags, rip-up clasts of glaciolacustrine silt, and trash lines of woody debris in forest at and near the limit of tsunami run-up. Similar features have been reported at sites of landslide-triggered tsunamis, notably in Alaska, Chile, Norway, and elsewhere in Canada. We grouped geomorphic features at Chehalis Lake on the basis of their areal distribution and their inferred formative energy. The geomorphic groups form a continuum, reflecting

    We describe the genetic divergence among 10 populations of redband trout Oncorhynchus mykiss gairdneri from the upper Columbia River drainage. Resident redband trout from two watersheds in the Kootenai River drainage and hatchery stocks of migratory Kamloops redband trout from Kootenay Lake, British Columbia, were analyzed using allele frequency data from microsatellite and allozyme loci. The Kamloops populations have significantly different allele frequencies from those of the Kootenai River drainage. Of the total genetic variation detected in the resident redband trout, 40.7% (microsatellites) and 15.5% (allozymes) were due to differences between populations from the two Kootenai River watersheds. The divergence among populations within each watershed, however, was less than 3.5% with both techniques. Our data indicate that watershed-specific broodstocks of redband trout are needed by fisheries managers for reintroduction or the supplementation of populations at risk of extinction.

    The Salmonid Rivers Observatory River Project (SaRON) is a multi-year, multi-disciplinary project which has been assessing the state of intact, pristine salmon rivers around the Pacific Rim. The goal of this research is to illuminate the natural ecological functions of these dynamic and diverse systems as well as use the information to describe targets for restoration of impacted rivers. Our research has shown that the Shifting Habitat Mosaic (SHM) of unconstrained floodplain reaches is important in structuring the freshwater and riparian components of salmon ecosystems. The amount and productivity of available habitat in flood plains is a primary control on salmon abundance. Our research around the Pacific Rim has found that channel complexity is correlated with salmon abundance. Juvenile fish density linearly increased, R2=0.95, with a greater number of channel separations and returns. Some rivers with high habitat values had low salmon abundances. For example, the Kitlope River in British Columbia has channel complexity, 0.09 nodes per square km of watershed area, showing high habitat availability. Thus, our model predicted 3.48 fish per square meter but measured values 0.56 fishes per square meter. Paleolimnological study demonstrated a legacy over-harvest in this system, explaining the discrepancy between the actual and reference value. These results will be establishing reference values and ranges in natural variation.

  19. The Hypersensitivity of Horses to Culicoides Bites in British Columbia

    Culicoides hypersensitivity is a chronic, recurrent, seasonal dermatitis of horses that has a worldwide distribution, but has only recently been reported in Canada. It is characterized by intense pruritus resulting in lesions associated with self-induced trauma. A survey of veterinarians and horse-owners in British Columbia showed no differences in susceptibility due to the sex, color, breed, or height of the horses. The prevalence of the disease in the 209 horses surveyed was 26%. Horses sharing the same pasture could be unaffected. The disease was reported primarily from southwestern British Columbia; it occurred between April and October and usually affected the ventral midline, mane, and tail. Horses were generally less than nine years old when the clinical signs first appeared ([unk]=5.9 yr). Culicoides hypersensitivity was common in the lineage of several affected horses, possibly indicating a genetic susceptibility. Most cases were severe enough to require veterinary attention and some horses were euthanized. PMID:17423117

    2005-05-01

    Sydenham's chorea (SC) became a well defined nosological entity only during the second half of the nineteenth century. Such progress was promoted by the availability of large clinical series provided by newly founded paediatric hospitals. This paper analyses the demographic and clinical features of patients with chorea admitted to the first British paediatric hospital (the Hospital for Sick Children, Great Ormond Street, London) between 1852 and 1936. The seasonal and demographic characteristics of SC during this time appear strikingly similar to those observed today, and witness the introduction of modern "statistically averaging" techniques in the approach to complex paediatric syndromes. Great Ormond Street (GOS) hospital case notes provide detailed descriptions of the "typical cases" of SC, and show that British physicians working in the early age of paediatric hospitals succeeded in recognising the most distinctive clinical features of this fascinating condition.

    The Annual Congress of the British Society for Immunology was well attended with over 1000 British scientists converging on the small Yorkshire town of Harrogate. Wide-ranging and varied, the topics covered included the biochemistry of signaling as well as sessions examining dietary influences upon mucosal immunity. The plenary session on the morning of Wednesday 6 December focused on immunology at the cell surface, where many speakers discussed the role of lipid rafts in immune cell signaling. A session of particular interest followed the plenary session, hosted by the Vaccine Immunology Group. Discussion centered around a number of novel vaccines currently under development, with the emphasis on finding alternatives to the use of hypodermic needles. A number of interesting posters affiliated to this session reflected the high quality of the research presented at the meeting in general. PMID:16025384

  2. Medicare financing and redistribution in british columbia, 1992 and 2002.

    Equity in healthcare in British Columbia is defined as the provision of services based on need rather than ability to pay and a separation of contributions to financing from the use of services. Physician and hospital services in Canada are financed mainly through general tax revenues, and there is a perception that this financing is progressive. This paper uses Gini coefficients, concentration indexes and Kakwani indexes of progressivity to assess the progressivity of medicare financing in British Columbia in 1992 and 2002. It also measures the overall redistributive effect of medicare services, considering both contributions to financing and use of hospital and physician services. The conclusion is that medicare does redistribute across income groups, but this redistribution is the result solely of the positive correlation between health status and income; financing is nearly proportionate across income groups, but use is higher among lower-income groups. Informed public debate requires a better understanding of these concepts of equity. PMID:19305738

    Seagrass ecosystems face widespread threat from reduced water quality, coastal development and poor land use. In recent decades, their distribution has declined rapidly, and in the British Isles, this loss is thought to have been extensive. Given increasing knowledge of how these ecosystems support fisheries production, the understanding of their potential rapid loss, and the difficulty in restoring them, it is vital we develop an understanding of the risks they are under, so that management actions can be developed accordingly. Developing an understanding of their environmental status and condition is therefore critical to their long-term management. This study provided, to our knowledge, the first examination of the environmental health of seagrass meadows around the British Isles. This study used a bioindicator approach and involved collecting data on seagrass density and morphology alongside analysis of leaf biochemistry. Our study provides, to the best of our knowledge, the first strong quantitative evidence that seagrass meadows of the British Isles are mostly in poor condition in comparison with global averages, with tissue nitrogen levels 75% higher than global values. Such poor status places their long-term resilience in doubt. Elemental nutrient concentrations and morphological change suggest conditions of excess nitrogen and probable low light, placing many of the meadows sampled in a perilous state, although others, situated away from human populations were perceived to be healthy. Although some sites were of a high environmental health, all sites were considered at risk from anthropogenic impacts, particularly poor water quality and boating-based disturbances. The findings of this study provide a warning of the need to take action, with respect to water quality and disturbance, to prevent the further loss and degradation of these systems across the British Isles.

    An extensional duplex consisting of fault-bounded blocks (horses) located between how-angle normal faults is exposed in Proterozoic strata in the Purcell Mountains of British Columbia, Canada. This is one of the first documented extensional duplexes, and it is geometrically and kinematically analogous to duplexes developed in contractional and strike-slip fault systems. The duplex formed within an extensional fault with a ramp and flat geometry when horses were sliced from the ramp and transported within the fault system.

    If travel has been one of the leitmotifs of Western imagination, Robinson Crusoe has certainly been one of its foremost incarnations. This British Ulysses foretold the global village, but also its problems. He predicted the end of distance, but also the triumph of isolation and anaesthetized loneliness. This paper provides an overview of the connections between Defoe's narrative and the new science and explores two versions of the story by two contemporary writers, Julio Cortazar and John Maxwell Coetzee.

    In late August last year the St George's Healthcare NHS Trust in south-west London signed what the Trust's Estates and Facilities team described as 'a historic partnership' with British Gas for a £12 m Energy Performance Contract energy reduction scheme--via which the energy company has guaranteed to deliver £1.1 m in annual savings over the next 15 years. The agreement will see British Gas replace four 35-year-old gas-powered steam boilers and an ageing CHP plant in the boiler house at the Trust's main acute facility, the StGeorge's Hospital in Tooting, and upgrade some of the associated infrastructure. British Gas will also maintain the new plant to ensure that the projected savings are achieved while the Trust owns the new assets. The Trust should gain financially--via lower energy costs and carbon emissions, while estates personnel will be better able to complete the many other estate maintenance issues that would otherwise be contracted out at one of London's biggest acute hospitals.
