Data
Our interdisciplinary, integrated science teams develop various data sets in support of the USGS mission areas. This information then aids natural resource managers in decision making and support of the complex issues they face in today's world. The data and tools listed here are official USGS data releases.

Occurrences of Apis mellifera filamentous virus (AmFV) sequences in public accessions of Apis mellifera and Varroa destructor
Honey bees (Apis mellifera), a critical agricultural pollinator in many areas, have a high rate of infection with a large DNA virus, Apis mellifera filamentous virus (AmFV), yet little is known about its ecology or impact on honey bee colonies, other than its ubiquity and apparent low virulence. This study scanned over 5,000 public data sets to detect AmFV sequences in honey bees as well as a para
Bibliography of hydrological and ecological research in the Great Basin terminal lakes, USA
This database contains literature citations and associated abstracts pertaining to the ecology and hydrology of terminal lakes in the Great Basin region of the western United States. This is not meant to be an exhaustive list, nor did we perform a systematic meta-analysis; rather, literature records were included based on topical relevance.
Vegetation and geomorphic surfaces in the Elwha River delta, Washington, after dam removal, derived from 2016 and 2018 aerial imagery and 2007, 2014, and 2018 field surveys
Removal of two large dams from the Elwha River, Washington USA, in 2011-2014 released ~20.5 metric tons (Mt) of impounded sediment, ~5.4 Mt of which was deposited in the river delta and estuary. This dataset presents measurements of geomorphic surfaces, vegetation colonization, and plant community development in the Elwha River delta and estuary after dam removal. Geomorphic surfaces and vegetatio
Capsaicin-treated bait trials for Argentine Black and White Tegu lizards in Georgia and Florida, USA 2020-2021
Invasive Argentine Black and White Tegu lizards (Salvator merianae) are trapped with chicken eggs when populations are discovered in the United States. Unfortunately, non-targeted mammals are trapped in tegu lizard traps which reduces trap efficacy. We evaluated if non-target mammal captures could be reduced by coating the chicken eggs with a known irritant to mammals (capsaicin) while maintaining
Sample collection information and microsatellite data for Northern Black Swifts in 6 colonies across Colorado, New Mexico and Idaho
This dataset contains sample collection information and microsatellite genotype data for Northern Black Swifts in 6 colonies across Colorado, New Mexico and Idaho. This data was collected to examine levels of genetic diversity and connectivity among Black Swift colonies and also to assess parentage at a subset of those sites. This study helps clarify the breeding system of the Black Swift and is t
Data on black-tailed prairie dog body mass, distance to nearest male and female black-footed ferret, distance to nearest American badger, and reencounter from early to late summer 2005 (Montana) and 2009 (South Dakota)
Our study was conducted in 2005 on 3 colonies of black-tailed prairie dogs on lands in Phillips County, Montana administered by the Bureau of Land Management and in 2009 on a colony of black-tailed prairie dogs on Buffalo Gap National Grassland, Pennington County, South Dakota managed by U.S. Forest Service. We live-trapped black-tailed prairie dogs in daylight with wire mesh traps and marked thei
Data on the effects of F1-V plague antigen vaccination and deltamethrin dust on black-tailed prairie dog annual survival and flea parasitism, South Dakota, 2007-2009
We studied black-tailed prairie dogs (Cynomys ludovicianus) on the Conata Basin, Buffalo Gap National Grassland, South Dakota, USA, 2007-2009. We live-trapped and sampled prairie dogs in 2007 (before known invasion of the plague bacterium Yersinia pestis), 2008 (the year of confirmed invasion), and 2009 (after invasion). Sampling was completed on three 9-ha plots treated annually with deltamethrin
Data on flea control using lufenuron and nitenpyram baits with black-tailed prairie dogs, South Dakota, 2021
We collected fleas from a colony of black-tailed prairie dogs on Buffalo Gap National Grassland, South Dakota, 2021. We collected flea data by combing prairie dogs and swabbing their burrows for fleas. Regarding combing, we anesthetized trapped prairie dogs (and their fleas) with isoflurane in induction chambers for processing. We combed each individual with a fine-tooth comb for 30 seconds to rem
North American Bat Monitoring Program (NABat) Integrated Summer Species Distribution Model: Predicted Tricolored Bat Occupancy Probabilities
These data contain the results from the North American Bat Monitoring Program's (NABat) integrated species distribution model (iSDM) for tricolored bats (Perimyotis subflavus). The provided tabular data include predictions (with uncertainty) for tricolored bat occupancy probabilities (i.e., probability of presence) based on data from the entire summer season (May 1–Aug 31), averaged from 2017-2022
North American Bat Monitoring Program (NABat) Bayesian Hierarchical Model for Winter Abundance: Predicted Population Estimates (2022 and 2023)
The dataset is comprised of historical observations and predictions of winter colony counts at known sites for three bat species (little brown bat, Myotis lucifugus; tricolored bat, Perimyotis subflavus; and big brown bat, Eptesicus fuscus). The dataset consists of two separate but related data files in tabular format (comma-separated values [.csv]). Each data set consists of predicted winter coun
Characteristics, presence of erosional features, and cover of vegetation and bare ground on fields formerly enrolled in grassland, wetland, and wildlife practices of the Conservation Reserve Program in the central and western United States from 2017 to 20
Data included in this data set are from edge-of-field surveys that recorded the presence of erosional features, cover of vegetation and bare ground, and management activities (e.g., haying) on 1092 fields that had expired from three types of conservation practices (grassland, wetland, and wildlife) in the Conservation Reserve Program. Field sampling data were recorded across six US Department of A
Data on separated and dead foals from Conger and Frisco Herd Management Areas, Utah, USA, between 2017 and 2020
We studied factors affecting separation of feral horse foals from their mothers and foal mortality, including variables such as group changes by the mother and behavior of the foal. We include data on feral horse foals that died or were separated, and their siblings. We conducted this study between 2017 and 2020 at two Herd Management Areas (HMAs) in western Utah, USA: Conger and Frisco. We conduc
