Glacier National Park alpine aquatic invertebrates, 2011-2013 This data release incorporates high-resolution geospatial and biological data and accompanies a peer-reviewed manuscript “Specialized meltwater biodiversity persists despite widespread deglaciation”. In this study, we tested the prediction that glacier retreat reduces biodiversity in mountain ecosystems through the loss of uniquely adapted meltwater stream species in Glacier National Park, USA. This dataset, “Glacier National Park alpine aquatic invertebrates, 2011-2013”, includes location and landscape data, as well as quantitative aquatic macroinvertebrate community data for 129 collection sites within Glacier National Park. Additionally, this dataset includes watershed drainage area, area of ice and perennial...

Two summit sites were established in 2003 on Dancing Lady and Bison Mountain, east of the continental divide. Two additional summit sites were established in 2004 on Pitamakin and Mt. Seward, also east of the continental divide. These four summit sites comprise a target region set up in accordance with the Global Observation Research Initiative in Alpine Environments (GLORIA). GLORIA was initiated by the University of Vienna in 2000 and protocols for operating target regions have been refined and...

In the Great Lakes, metals have sometimes been identified as limiting the acquisition of macronutrients, mostly in off-shore waters that are relatively isolated from tributary inputs and sediment interactions. We hypothesized that another area where metals might be important was within harmful algal blooms (HABs). Harmful algal blooms are more likely to occur where N and P loads are elevated due to human activities, but short-term growth assays still often find summer bloom communities are...

Lost River suckers (LRS; Deltistes luxatus) and shortnose suckers (SNS; Chasmistes brevirostris) have been captured and tagged with passive integrated transponder (PIT) tags during their spawning migrations in each year since 1995.PIT tagged species were encountered in netting efforts, remote transceivers, and active scanning on bird colonies across the Upper Klamath River...

The samples were processed at the Utah Water Science Center and geochemical analysis was performed at the University of Utah's ICP-MS Metals and Strontium Isotope Facility (Salt Lake City, Utah).

These datasets, for the Klamath Oregon/California, USA (KLAM) sage-grouse population, include: 1) a set of 78 categorical raster layers illustrating a time series (decade intervals) of potential future habitat, and 2) a set of 15 uncategorized raster layers illustrating potential change in habitat classification across space, after simulating...

The impact of this mortality on species census size is not understood, due in part to the difficulty of estimating population size for this highly migratory and elusive species. Genetic effective population size (Ne) could provide an index of census population size if other factors affecting Ne are stable. In support of this and other population-genetic studies, we analyzed two temporally spaced cohorts: 96 hoary bats collected in 2009-2010 and an additional 96 collected in 2017-2018. Samples consisted of wing clips removed from archived carcasses and were obtained by agreement from the U.S. Fish and Wildlife...

They include maps of soil pH, electrical conductivity, soil organic matter, and soil summed fine and very fine sand contents that were created using both 2D and 3D modeling strategies.

(2023; IP-156006). In this study a Dynamic Energy Budget (DEB) model for the eastern oyster, Crassostrea virginica, was run under different scenarios of current (2014–2020) and future (2041–2050) temperature and salinity conditions across six key Texas and Louisiana estuaries to derive an aquaculture index, based on survival and time to market size, and a restoration index, based on survival and reproductive output.

Shellfish, USGS Science Data Catalog (SDC), Fewer tags Greater sage-grouse genetic data and R code for evaluating conservation translocations in the northwestern United States, 1992–2021 Conservation translocations are a common wildlife management tool that can be difficult to implement and evaluate for effectiveness. Genetic information can provide unique insight regarding local impact of translocations (e.g., presence and retention of introduced genetic variation) and identifying suitable source and recipient populations (e.g., adaptive similarity). We developed two genetic data sets and wrote statistical code to evaluate conservation translocation effectiveness into the isolated northwestern region of the greater sage-grouse (Centrocercus urophasianus) distribution and to retrospectively evaluate adaptive divergence among source and recipient populations. Our first data set was microsatellite-based... Tags: Centrocercus urophasianus, Ecology, Genetics, Idaho, Nevada, All tags...

Over the period of the data collection, we had 29 mountain lions equipped with telemetry collars and we investigated clusters of locations when GPS collar locations were in the same area for three nights -- we used this criteria to identify potential predation events by mountain lions, and then hiked to the GPS cluster location on foot to search for a kill site and to identify the species consumed. Collared mountain lions were both males and females, and species consumed included mule deer, feral horses, bighorn sheep, coyotes, other mountain lions, badgers, beaver,...

Natural VEN epizootics and observations studies in wild populations suggest that temperature may be an important disease cofactor. Here, a controlled laboratory exposure study provides evidence for a direct relationship between temperature and the progression of viral erythrocytic necrosis (VEN) in Pacific herring. Waterborne exposure of Pacific herring to kidney homogenates containing ENV resulted in the establishment of infections, characterized by high infection prevalence (89%; 40/45) and mean viral...

Snakes were fitted with radio-transmitters and teams of 2-4 biologist listened for signals from transmitters every seven days to determine if snakes were alive or dead. Survival data was then modeled in Program MARK to assess the effect of aerially applied toxic baits on snake mortality, including the effect of snake size covariates. In addition, this dataset contains snake capture information from reference sites on Guam that was used to demonstrate that our sample was representative of the size distribution in limestone forest habitat on...

The APEX site is managed by the Bonanza Creek LTER (Long Term Ecological Research). Nine instrument monitoring sites (APEX1-APEX9) were established in April 2018. To quantify permafrost and thaw zone characteristics along the instrumented gradient, electrical resistivity tomography (ERT) data were collected in August 2018 along four 82 meter (m)-long transects between select sites: APEX1-3, APEX5-3, APEX5-7, and APEX6-8.
