The CoRE (Contractions or Range Expansions) database contains a library of published literature and data on species range shifts in response to climate change. Through a systematic review of publications returned from searches on Google Scholar, Web of Science, and Scopus, we selected primary research articles that documented or attempted to document species-level distribution shifts in animal or plant species in response to recent anthropogenic climate change. We extracted data in four broad categories: (i) basic study information (study duration, location, data quality and methodological factors); (ii) basic species information (scientific names and taxonomic groups); (iii) information on the observed range shifts...

This is an examination of the diet of a threatened snake, giant gartersnake (Thamnophis gigas). Prey preference, prey selection and prey availability (in the laboratory and the field) were measured to understand prey dynamics for better conservation of this snake. In the laboratory, olfactory trials were performed on neonate snakes and tongue-flicks, lounges and attacks were counted and calculated into 'tongue-flick attack scores', a measure of prey preference. Prey-choice trials were used to measure prey selection in the laboratory. In the field, we measured prey choice and prey availability to gain an understanding of prey choice in nature. These data support the following publication: Ersan, J.S., Halstead,...
Between 2004 and 2011 bighorn sheep were darted in Glacier National Park and in Dinosaur National Monument. Blood was drawn. These are the genotypes resulting from an Ovine HD array from the bighorns. The first 3 columns refers to bighorn sheep identifiers: 'Herd_Unit', 'IndID', and 'AgencyID'. IndID is the identifier assigned at Montana State University. Subsequent columns each represent a locus, with the values in the locus representing the allele.
The Willamette River Basin, Oregon, supports native fish species and non-native fish species introduced for sport fisheries or accidentally from aquarium releases and other sources. Based on fish surveys completed from 1998 to 2018 by Oregon State University and records from the Oregon State University Ichthyology Collection, the Willamette River Basin has 34 native fish species found upstream of the confluence of the Willamette and Columbia Rivers and 28 non-native fish species. Each native and non-native fish species has its own thermal tolerances and diet, spawning, and vertical preference traits. This means that distributions of native and non-native fishes along the river network are shaped by physical factors...
These data were compiled to assess the size, structure, and health of various populations of Actinemys pallida along the length of the Mojave River. Objective(s) of our study were to determine the extent of injuries and abnormalities within our Actinemys pallida populations (including statistical analyses comparing injuries with turtle sex and size) and estimate the cause(s) of the injuries and abnormalities. These data represent injuries and abnormalities from the effects of physical hazards encountered by turtles in their habitats. These data were collected in the Mojave Desert of California at three separate study sites along a length of the Mojave River in San Bernardino County between May 1998–October 1999...
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). After toxicant-mediated suppression of a brown treesnake population on Guam, we simultaneously used visual encounter surveys to estimate rodent abundance and radiotelemetry to document movement behavior of surviving snakes located in the Habitat Management Unit (HMU) in Northern Guam, Andersen Air Force Base. The impact...

This data release contains eight datasets that represent the entirety of the data collected for a study that examined breeding-bird densities in native mixed-grass prairie from 2003 to 2012 at and adjacent to wind facilities in North Dakota and South Dakota, USA. Data were collected to determine breeding-bird density per 100 hectares (ha) by distance bands from turbines and by excluding habitat that may not be considered suitable as breeding habitat for particular bird species. A subset of the data that included only one year prior to turbine construction and several years post-construction and that lent itself to a before-after-control-impact (BACI) assessment was published as its own data release and paper in...
We investigated habitat selection by 28 male greater sage-grouse during each of three years (2016-2018) after a 113,000-ha wildfire in a sagebrush steppe ecosystem in Idaho and Oregon. During the study period, seeding and herbicide treatments were applied for habitat restoration. This dataset includes pre-fire land cover, post-fire vegetation, and post-fire treatment data within 500-m buffers of sage-grouse telemetry locations and random locations within the perimeter of the wildfire. These data were used to analyze habitat selection by sage-grouse in each of the three years.
We collated existing quantitative data on avian dietary composition of 58 waterbird species that make use of the Chesapeake Bay. From this database, we quantified the relative importance of forage taxa to the diets of each waterbird species. This data will enable us to develop a comprehensive suite of forage taxa indicators whose abundance and distributions can be monitored as a proxy for Chesapeake Bay ecosystem health. These data support a paired USGS authored publication.
We present a tabular data set representing values to estimate apparent hatch-year survival to adulthood and natal dispersal probabilities between two breeding groups of the Northern Great Plains piping plover (Charadrius melodus) used in a multievent capture-mark-resight model from 2014-2019. Focusing on the Northern Missouri River and U.S. Alkali Wetlands breeding groups. In addition, several covariates were included representing habitat and social variables.
These raw survey data and associated explanatory covariates were used to model western bumble bee occupancy across the western conterminous United States from 1998 to 2020. These data underlie the analyses found in the publication of “Recent and future declines of a historically widespread pollinator linked to climate, land cover, and pesticides” by Janousek et al. 2023 in the Proceedings of the National Academy of Sciences vol. 120, issue 5. The covariate data are provided in a scaled format for use in the occupancy model, and the scaling parameters used to transform the data to the original (real) scale are provided in the scaling information file.
These data are the result of an intersection between a surface representing the delta-finite rate of population change and another surface representing Greater Sage-grouse abundance and space-use. It was used to rank candidate sites according to greatest potential impact to Greater Sage-grouse populations resulting from the presence of geothermal energy activity. In 2022, candidate geothermal sites were identified in Nevada and eastern California, then buffered by 10 kilometers. While the extent of the overall raster layer encompasses a very large swath of the western US, data values are limited to fall within these 10 kilometer buffers. These data support the following publications: Coates, P.S., Prochazka, B.G.,...

Lifespan of salt marshes in Massachusetts (MA) are calculated using conceptual marsh units defined by Ackerman and others (2022). The lifespan calculation is based on estimated sediment supply and sea-level rise (SLR) predictions after Ganju and others (2020). Sea level predictions are local estimates which correspond to the 0.3, 0.5, and 1.0 meter increase in Global Mean Sea Level (GMSL) scenarios by 2100 from Sweet and others (2022). The U.S. Geological Survey has been expanding national assessment of coastal change hazards and forecast products to coastal wetlands, including Massachusetts salt marshes, with the intent of providing Federal, State, and local managers with tools to estimate the vulnerability and...

Output of analysis describing habitat selection, the location of contacts and the intersection of the two. Based on GPS collar data from 2002 to 2011.
We present a tabular data set representing values used to evaluate hypotheses of breeding habitat selection for immigrants and returning Northern Great Plains piping plovers (Charadrius melodus) from 2014 – 2019. The associated manuscript uses network analysis approach to evaluate five hypotheses of habitat selection. In this approach breeding locations were nodes and successive year breeding attempts form the edges (immigration) and self-loops (fidelity). Included in the dataset are covariates of habitat amount, conspecific density, and habitat quality, as well as other fields used in the analysis. In addition, we include descriptive breeding location-specific metrics from the network graphs.
We outfitted nine condors in a flight pen with patagial tags, each with a unique ID, and a proprietary solar powered Global Positioning System-Global System for Mobile Communications (GPS-GSM) telemetry device weighing 50 g (Cellular Tracking Technologies, LLC, Rio Grande, NJ). The units collected tri-axial acceleration data at a rate of 20 Hz. Data were transmitted once daily over cellular networks and then downloaded to a server.

Accessing the Data The BBS releases its data on an annual basis. The “Child Items” section below provides links to the most recent as well as historic data releases. Each annual release includes all previously released data, plus all subsequent taxonomic...
Wildfire events are becoming more frequent and severe on a global scale. Rising temperatures, prolonged drought, and the presence of pyrophytic invasive grasses are contributing to the degradation of native vegetation communities. Within the Great Basin region of the Western United States, increasing wildfire frequency is transforming the ecosystem toward a higher degree of homogeneity, one dominated by invasive annual grasses and declining landscape productivity. Greater sage-grouse (Centrocercus urophasianus; hereafter sage-grouse) are a species of conservation concern that rely on large tracts of structurally and functionally diverse sagebrush (Artemisia spp.) communities. Using a 12-year (2008-2019) telemetry...
Remote cameras (“trail cameras”) are a popular tool for non-invasive, continuous wildlife monitoring, and as they become more prevalent in wildlife research, machine learning (ML) is increasingly used to automate or accelerate the labor-intensive process of labelling (i.e., tagging) photos. Human-machine hybrid tagging approaches have been shown to greatly increase tagging efficiency (i.e., time to tag a single image). However, those potential increases hinge on the extent to which an ML model makes correct vs. incorrect predictions. We performed an experiment using a ML model that produces bounding boxes around animals, people, and vehicles in remote camera imagery (MegaDetector), to consider the impact of a ML...
