USGS research into environmental stressors (e.g., climate, drought, floods, wildland fire) and anthropogenic stressors (e.g., energy production, urban encroachment, water abatement) provides managers with information to reduce or eliminate impacts from stressors to fish and wildlife populations and advances our understanding of the efficacy of conservation and adaptation actions to mitigate land-use and climate change impacts on sensitive species.

Ungulate Migrations of the Western United States, Volume 1 Ungulate Migrations of the Western United States, Volume 1
This is the data archive for the publication Ungulate Migrations of the Western United States, Volume 1 (Kauffman et al. 2020) 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...

Hawaii Island, Hawaiian hoary bat roosting ecology and detection 2018-2019 Hawaii Island, Hawaiian hoary bat roosting ecology and detection 2018-2019
The Hawaiian hoary bat (Lasiurus cinereus semotus), a federally and state listed endangered subspecies, is the only extant native terrestrial mammal in the Hawaiian archipelago. It is an insectivorous, solitary and foliage-roosting species that generally roosts alone or in mother-pup family groups. A total of 58 bats (17 female; 41 male; 56 adult; 2 juvenile) were captured at multiple...
Lanai habitat and ecological associations of two non-native ungulate species 2011 Lanai habitat and ecological associations of two non-native ungulate species 2011
This series of five raster datasets includes three input rasters developed to model habitat suitability for two ungulate species on the island of Lanai; the two habitat suitability model raster datasets are also part of this data release. Input datasets were derived from WorldView-2 data to create vegetation (hereafter, NDVI) and bare ground indices, and from a Digital Elevation Model...

Wolf Hematology in the Superior National Forest, 1989-1993 Wolf Hematology in the Superior National Forest, 1989-1993
Hematology and body mass were studied in nine female and five male free-ranging wolves in the Superior National Forest handled 4-17 times during 1989-1993. The dataset includes the following data for each wolf studied: wolf identifier, dates caught, sex, age, body mass in kg, adjusted body mass in kg, and values of hemoglobin (Hb), red blood cells (RBC), mean corpuscular hemoglobin (MCH)

Energetic and health effects of protein overconsumption constrain dietary adaptation in an apex predator Energetic and health effects of protein overconsumption constrain dietary adaptation in an apex predator
Studies of predator feeding ecology commonly focus on energy intake. However, captive predators have been documented to selectively feed to optimize macronutrient intake. As many apex predators experience environmental changes that affect prey availability, limitations on selective feeding can affect energetics and health. We estimated the protein:fat ratio of diets consumed by wild...

Comparison of aerial thermal infrared imagery and helicopter surveys of bison (Bison bison) in Grand Canyon National Park, USA Comparison of aerial thermal infrared imagery and helicopter surveys of bison (Bison bison) in Grand Canyon National Park, USA
Aerial thermal infrared (TIR) surveys are an attractive option for estimating abundances of large mammals inhabiting extensive and heterogenous terrain. Compared to standard helicopter or fixed-wing aerial surveys, TIR flights can be conducted at higher altitudes translating into greater spatial coverage and increased observer safety; however, monetary costs are much greater. Further...

Body size and digestive system shape resource selection by ungulates: A cross-taxa test of the forage maturation hypothesis Body size and digestive system shape resource selection by ungulates: A cross-taxa test of the forage maturation hypothesis
The forage maturation hypothesis (FMH) states that energy intake for ungulates is maximised when forage biomass is at intermediate levels. Nevertheless, metabolic allometry and different digestive systems suggest that resource selection should vary across ungulate species. By combining GPS relocations with remotely sensed data on forage characteristics and surface water, we quantified...

Predicted distribution of a rare and understudied forest carnivore: Humboldt marten (Martes caurina humboldtensis) Predicted distribution of a rare and understudied forest carnivore: Humboldt marten (Martes caurina humboldtensis)
Many mammalian species have experienced range contractions. Following a reduction in distribution that has resulted in apparently small and disjunct populations, the Humboldt marten (Martes caurina humboldtensis) was recently designated as federally Threatened and state Endangered. This subspecies of Pacific marten occurring in coastal Oregon and northern California, also known as...

Be a wolf researcher! Wolf pup ethogram Be a wolf researcher! Wolf pup ethogram
Ethology is the study of behavior, and an ethogram is a list of behaviors, typically of a single species. For this ethogram we have selected a few representative behaviors that pups will exhibit during various growth phases, and therefore, this ethogram is not exhaustive. You will likely observe behaviors not detailed in this booklet (be sure to keep notes of your observations on the...
