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.

Serpentoviruses in free-ranging invasive pythons and native colubrids in southern Florida, United States, 2018-2020
The presence of serpentoviruses in Burmese pythons (Python bivittatus) and native snakes were collected and compiled to characterize serpentovirus in wild free-ranging pythons and free-ranging native snakes within the invasive range of the pythons in southern Florida. Virus presence was tested in 318 pythons and 219 Native snakes, primarily within the Greater Everglades Ecosystem of south Florida.
State-and-Transition Simulation Models to explore post-fire habitat restoration in three greater sage-grouse (Centrocercus urophasianus) Priority Areas for Conservation, USA (2018-2068)
Wildfires are increasingly modifying wildlife habitat in the western United States and managers need ways to scope the pace and degree to which post-fire restoration actions can re-create habitat in dynamic landscapes. We simulated post-fire revegetation and greater sage-grouse (Centrocercus urophasianus) habitat restoration using a spatially explicit state-transition simulation model (STSM) devel
Voucher and metagenetic sequencing of DNA barcodes of wild-collected bees (Apoidea) from Iowa, USA
High-throughput methods for identification of pollinator taxa are desirable to improve our understanding of pollinator distributions, population trends, and ecology. Genetic sequencing of taxonomically informative 'barcode' loci is one high-throughput strategy, which can be applied to individual specimens using Sanger technology and to complex mixtures using metabarcoding technology. This study ge
Sagebrush projections for greater sage-grouse core areas in Wyoming, USA, 2018-2100
Sagebrush (Artemisia spp.) ecosystems provide critical habitat for the near-threatened Greater sage-grouse (Centrocercus urophasianus), and future loss of sagebrush habitat because of land use change and global climate change is of concern. We used a dynamic additive spatio-temporal model to estimate effects of climate (spring-summer temperatures and precipitation) on sagebrush cover dynamics at 3
Paleoecological data from sediment collected in 2020 from Santa Fe Lake, New Mexico
This dataset contains carbon and nitrogen stable isotope values, percent carbon and percent nitrogen, algal pigment data, and diatom taxonomy from lake sediment layers dating back to 1749 Common Era (CE) for Santa Fe lake, New Mexico. Subalpine and alpine lakes are typically sensitive indicators of anthropogenically driven global change. Lake sediment records in the western United States have docu
A neutral landscape approach to evaluating the umbrella species concept for greater sage-grouse in northeast Wyoming, USA
Greater sage-grouse (Centrocercus urophasianus) has been identified as a potential umbrella species with the assumption that conservation of their habitats in sagebrush ecosystems may benefit multiple other wildlife species, but co-occurrence with an umbrella species does not necessarily guarantee species will respond positively to management for sage-grouse. This may be particularly true for ecot
Percent vegetation cover, bare ground and presence of erosional features on managed Conservation Reserve Program fields across central and western United States, 2016-2019
Data included in this data set are from edge-of-field surveys of managed fields that recorded the presence of erosional features and cover of vegetation and bare ground on 320 Conservation Reserve Program (CRP) fields across central and western United States. Field sampling data was recorded across six US Department of Agriculture Farm Production Regions (Corn belt, Lake states, Mountain, Northern
Gunnison sage-grouse predicted gene flow (conductance) surfaces, Colorado, United States
Habitat fragmentation and degradation impacts an organism's ability to navigate the landscape, ultimately resulting in decreased gene flow and increased extinction risk. Understanding how landscape composition impacts gene flow (i.e., connectivity) and interacts with scale is essential to conservation decision-making. We used a landscape genetics approach implementing a recently developed statisti
Circuit-based potential fire connectivity and relative flow patterns in the Great Basin, United States, 270 meters
The rasters in this dataset represent modeled outputs of potential fire connectivity and relative flow patterns in the Great Basin. We define ‘fire connectivity’ as the landscape’s capacity to facilitate fire transmission from one point on the landscape to another. We applied an omnidirectional circuit theory algorithm (Omniscape) to model fire connectivity in the Great Basin of the western United
Attributed North American Grid-Based Offshore Sampling Frames
This sampling frame is a set of grid-based, finite-area frames spanning the offshore areas surrounding Canada, the United States, and Mexico, and is intended for use with the North American Bat Monitoring Program (NABat). A Generalized Random-Tessellation Stratified (GRTS) Survey Design draw was added to the sample units from the raw sampling grids (https://doi.org/10.5066/P9XBOCVV). The GRTS surv
Brown treesnake movement following snake suppression in the Habitat Management Unit on Northern Guam from 2015
Animals move to locate important resources such as food, water, and mates. Therefore, movement patterns can reflect temporal and spatial availability of resources as well as when, where, and how individuals access such resources. To test these relationships for a predatory reptile, we quantified the effects of prey abundance on the spatial ecology of invasive brown treesnakes (Boiga irregularis).
Genotypes and cluster definitions for a range-wide greater sage-grouse dataset collected 2005-2017 (ver 1.1, January 2023)
Monitoring change in genetic diversity in wildlife populations across multiple scales could facilitate prioritization of conservation efforts. We used microsatellite genotypes from 7,080 previously collected genetic samples from across the greater sage-grouse (Centrocercus urophasianus) range to develop a modelling framework for estimating genetic diversity within a recently developed hierarchical
