Genomic Determination of Hoary Bat Population History and Trend Observing and counting bats is extremely difficult. Bats hide during the day, fly in darkness, and most species in the United States (US) become inactive and inaccessible in cryptic hibernation sites for 7-8 months each year. More than 40 different species of bats occur year-round in the US, yet reasonable population estimates exist for very few. Populations of US bats face new and unprecedented threats from white-nose syndrome (WNS) and industrial wind turbines. Like WNS, wind energy development might adversely affect entire populations of bats. Species of bats dying at wind turbines in the greatest numbers rank among the most cryptic, elusive, and poorly understood. Hoary bats (Lasiurus cinereus) compose approximately...

In support of binational Great Lakes fishery management the objectives of this survey were to: provide estimates of densities of key forage and predator species in the western basin of Lake Erie, to assess seasonal and spatial distributions of fishes, and to assess year class strength. A systematic grid sampling approach with 41 stations was sampled during June (Spring) and September (Autumn), starting in 2013. This data release adds 2017 data to the set – making it five years of continuous observation.

Ontario, Population dynamics, biota, inlandWaters, Fewer tags Final Report: Using light-level geolocators to measure breeding propensity of mottled ducks in the Western Gulf Coast The Western Gulf Coast (WGC) is home to approximately 90% of the worldwide population of mottled ducks (Anas fulvigula), a non-migratory species that must satisfy its annual cycle needs within a small geographic range. Available population data suggest the WGC mottled duck population has experienced a slight to moderate decline across its range since 1985 (Gulf Coast Joint Venture [GCJV] Mottled Duck Working Group, Unpublished report). Because of its population status and reliance on a restricted geography, the mottled duck has been identified as a focal species for the U.S. Fish and Wildlife Service, a priority species in Texas and Louisiana Comprehensive Wildlife Conservation Plans, and the subject of targeted...

Synopsis: To date, there is a lack of well-controlled field experiments that disentangle the effects of the intervening matrix from other landscape variables (e.g., patch geography or quality) that might influence animal dispersal among patches. We performed a field experiment to investigate how the movement of a delphacid planthopper (Prokelisia crocea) among discrete patches of prairie cordgrass (Spartina pectinata) is affected by the composition of the matrix (mudflat, native nonhost grasses, and the introduced grass smooth brome [Bromus inermis]). Within each matrix type, marked planthoppers were released onto experimental cordgrass patches that were made identical in size, isolation, and host plant quality....

The Lake Erie survey examined the food web across a nearshore to offshore gradient, matching the sampling design the preceding USGS studies of the other four Great Lakes (2010-2013). We sampled all trophic levels in all three lake basins across multiple seasons in order to determine nutrient availability...

Data collection began in 2008 and continued until 2013, and the prescribed fire was applied in the fall of 2010. These data support the following paper: Halstead, B. J., Thompson, M.

The tabular data set consists of measurements of annuli widths from Walleye dorsal spine thin sections. Walleye spines were sampled non-lethally from fish that were selected for acoustic telemetry tag implantation in several interrelated investigations. The telemetry work was coordinated through the Great Lakes Acoustic Telemetry Observation System (GLATOS, https://glatos.glos.us/). Measurements were obtained from digital images of spine thin sections within the zipped file provided, and can be used to understand the age and growth characteristics of tagged Walleye. These data can be cross-referenced with biological and tagging data...

Sampling was conducted using a backpack electrofishing unit at two reference sites including Cane Creek and Sugar Creek, and at three mine impact sites including Sugar Creek and Cinnabar Creek. Juvenile Bull Trout (Salvelinus confluentus) were present at all five sites and were the primary species targeted during our sampling effort. Additional tissue samples of Sculpin, and amphibians were taken when available. Where possible, a two pass (quantitative depletion) electrofishing survey was conducted at each site for non-USGS stakeholders (Nez Perce Tribe and Idaho Department of Fish and...

In addition, data on streamflow, stream temperature, and surrounding land cover for each stream were compiled from existing sources.
