Zebra anthrax carcass site pathogen and soil data from Namibia, 2010-2021

Datasets collected from monitored zebra anthrax carcass sites in Etosha National Park, Namibia, 2010-2021. One data file describes the anthrax mortality, soil characterization of the carcass sites and details on the types and timing of different sampling efforts at these sites. The other data file is counts of Bacillus anthracis spores in surface soils collected annually at these carcass sites.

Ungulate Migrations of the Western United States, Volume 3

This is the data archive for the publication Ungulate Migrations of the Western United States, Volume 3 (Kauffman et al. 2022) and includes the collection of GIS map files that are mapped and described in the report. These map files are meant to provide a common spatial representation of the mapped migrations. This data release provides the means for ungulate migrations to be mapped and planned fo

Daily ages of young-of-year Silver Chub from western Lake Erie, 2017-2018

Daily ages of young-of-year Silver Chub were estimated from counts of rings in lapilli otoliths. Lapilli were mounted to glass slides with thermoplastic cement and sanded to the core with 2000 grit sandpaper to expose daily rings. To improve clarity, sanded otoliths were polished with 0.3 μm alumina powder and a polishing cloth prior to viewing. To estimate daily age, counts of rings in otoliths w

Biogeochemical data from microcosm experiments to evaluate treatment of acid-rock drainage in selected counties in Tennessee

The U.S. Geological Survey, in cooperation with the Tennessee Department of Transportation, conducted an investigation of acid-rock drainage from road cuts in Tennessee during 2014-2015. The Devonian Chattanooga Shale contains disseminated pyrite and is a primary producer of acid-rock drainage (ARD) in Tennessee. One objective of the overall investigation was to attenuate ARD by manipulating the i

Stream Temperature and Dissolved Oxygen Responses to Small Dams and Dam Removal in Massachusetts

Small, surface-release dams are ubiquitous across the U.S. and have the potential to alter stream flow, impede sediment and nutrient transport, and fragment biotic assemblages. To mitigate these and other ecological impacts and reduce public safety hazards, dam removal has become an increasingly prevalent method of stream restoration. However, few streams have been consistently monitored before an

Movement Data of Partially Migratory Brown Pelicans from the South Atlantic Bight

This dataset contains locations acquired from GPS-tagged Brown Pelicans in the South Atlantic Bight. Locations correspond to the movements of pelicans tracked during the autumn migratory period (post-breed to the following spring, with length of deployment varying individually) from 2017-2020. Additional metrics include intrinsic and extrinsic variables both measured and acquired which may influen

American alligator demographic and harvest data from Georgetown County, South Carolina, 1979-2017

The American alligator (Alligator mississippiensis) is a species of ecological and economic importance in the southeastern United States. Within South Carolina, alligators are subject to private and public harvest programs, as well as nuisance removal. These management activities can have different impacts across alligator size classes that may not be apparent through widely-used monitoring techni

Ungulate Migrations of the Western United States, Volume 2

In-vitro Propagation and Fish Assessments to Inform Restoration of Dwarf Wedgemussel (Alasmidonta Heterodon)

The dwarf wedgemussel (Alasmidonta heterodon) is a federally endangered freshwater mussel that once ranged from New Brunswick to North Carolina, but now only exists in isolated populations throughout its diminished range. Laboratory propagation in conjunction with augmentation or reintroduction is considered a critical component of dwarf wedgemussel restoration. The presented data aimed to I) deve

Population genetic analysis of three aquatic macroinvertebrate species from samples in Grand Canyon (Arizona, USA) tributaries and nearby reference streams, 2016-2021

This dataset contains single nucleotide polymorphism (SNP) information for aquatic insect species collected in tributaries of the Colorado River in Grand Canyon (Arizona, USA), as well as SNP information for individuals collected from reference reaches of the Upper Colorado River Basin in Utah. This dataset focuses specifically on three species that were common and widely distributed throughout tr

White-tailed deer necropsy data from Wisconsin, 2017-2021

Necropsy data collected from naturally-occurring white-tailed deer mortalities in southwestern Wisconsin from 2017-2021. Hunter-harvest mortalities are not included.

Concentrations of Perfluoroalkyl Substances in the Eggs of Brown Pelicans from Charleston, SC (2019)

This dataset contains concentrations of perfluoroalkyl substances (PFAS) measured in the eggs of brown pelicans nesting near Charleston, SC, USA, as well as movements of brown pelicans tracked with GPS-Platform Terminal transmitters. In total, 36 eggs were measured from three breeding colonies of brown pelicans for the presence of 24 PFAS analytes using LC-MS/MS. Concentrations were then analyzed
