White-tailed deer and sharp-tailed grouse data used in constrained generalized additive models to enhance survival analyses and incorporate ecological theory

Grouse: These data on sharp-tailed grouse survival times are provided for individuals wanting to run an age-period survival analysis. Entry and exit times are expressed in integer days from the start of the study. Entry age and exit age expressed in integer days are also included. Data are structured to implement survival analysis. White-tailed Deer: These data on white-tailed deer survival times

Expert assessments of hypotheses concerning the etiological agent(s) of Stony Coral Tissue Loss Disease collected during a rapid prototyping project

This dataset is from expert elicitation of a panel of 15 experts with knowledge of stony coral tissue loss disease (SCTLD) and its impacts on coral reefs. We gathered this group of 15 participants with diverse expertise who had previously studied SCTLD including at universities and various government agencies as microbiologists, pathologists, disease ecologists, population ecologists, and coral ex

Movement and tag evaluation of two prairie fishes in Oklahoma, USA, October-June (2018-2020)

The first portion of this dataset provides the survival, retention, and growth of Emerald Shiner Notropis atherinoides (EMS) tagged with passive integrated transponder (PIT) tags and Arkansas River Shiner Notropis girardi (ARS) tagged with visible implant elastomer (VIE), PIT, and micro transponder p-Chip tags. Experiments were undertaken in the laboratory at Oklahoma State University, Stillwater,

Isotopic Data for Fishes in Wyoming, USA

Trophic studies can provide valuable information on the risk an invader poses to native species. Brook Stickleback Culaea inconstans is an invasive fish species in Wyoming whose effect on native fish assemblages is poorly understood. Our goal was to understand the potential for competitive interactions between Brook Stickleback and native fishes. We used stable isotopes of carbon (ẟ13C) and nitrog

Sample locations 2022 SARS-CoV-2 testing in little brown bats

The potential introduction of SARS-CoV-2, the virus responsible for the COVID-19 pandemic, into North American bat populations is of interest to wildlife managers due to recent declines of several species. Populations of little brown bats (Myotis lucifugus) have collapsed due to white-nose syndrome (WNS), a disease caused by the introduction and spread of the fungal pathogen Pseudogymnoascus destr

Real-time quaking-induced conversion assay data for membrane-fed ticks and wild-fed tick and deer tissues from hunter harvested white-tailed deer from Wisconsin, 2021

Real-time quaking induced conversion assay data from artificial membrane feeding assays of ticks and of engorged tick, ear tissue and lymph node samples from hunter harvested white-tailed deer heads from Wisconsin that were harvested during the 2021 hunting season.

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

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
