This model was used in Camouflage mismatch in seasonal coat color due to decreased snow duration (Mills et al. 2013, PNAS). Information about this model and analysis can be found at: http://www.pnas.org/content/110/18/7360.abstract.

This map contains projected habitat suitability for the greater sage-grouse (centrocercus urophasianus) under the Third Generation Coupled Global Climate Model (CGCM 3.1). In support of the Pacific Northwest Climate Change Vulnerability Assessment (www.climatevulnerability.org), we developed a method to model habitat suitability in which we built correlative climate suitability models for 366 terrestrial animal species at a relatively coarse spatial resolution for the entire North American continent using species range maps and 23 bioclimatic variables. We then applied the models to both current and projected future climate data downscaled to a moderately fine resolution for western North America. We refined the...

This dataset contains the result of the bioclimatic-envelope modeling of the six mammal species -- (a) New Mexican Jumping Mouse (Zapus hudsonius luteus), (b) Northern Pygmy Mouse (Baiomys taylori), (c) Gunnison's Prairie Dog (Cynomys gunnisoni), (d) Black-tailed Prairie Dog (Cynomys ludovicianus), (e) American Pika (Ochotona princeps), and (e) Swift Fox (Vulpes velox) -- in the South Central US using the downscaled data provided by WorldClim. We used five species distribution models (SDM) including Generalized Linear Model, Random Forest, Boosted Regression Tree, Maxent, and Multivariate Adaptive Regression Splines (MARS) and ensembles to develop the present day distributions of the species based on climate-driven...

Climate often drives ungulate population dynamics, and as climates change, some areas may become unsuitable for species persistence. Unraveling the relationships between climate and population dynamics, and projecting them across time, advances ecological understanding that informs and steers sustainable conservation for species. Using pronghorn (Antilocapra americana) as an ecological model, we used a Bayesian approach to analyze long-term population, precipitation, and temperature data from 18 subpopulations in the southwestern United States. We determined which long-term (12 and 24 months) or short-term (gestation trimester and lactation period) climatic conditions best predicted annual rate of population growth...

Dataset includes weekly individual snowshoe hare observations on coat color molt phenology collected in field study site near Seeley Lake MT, USA. Data were analyzed and results published at: Mills L.S., Zimova M., Oyler J., Running S., Abatzoglou J.T., Lukacs P.M. 2013 Camouflage mismatch in seasonal coat color due to decreased snow duration. Proceedings of the National Academy of Sciences of the United States of America 110(18), 7360-7365. (doi:10.1073/pnas.1222724110).

In partnership with South Atlantic Landscape Conservation Cooperative members, we assessed current and projected connectivity for three species that inhabit bottomland hardwoods throughout the southeastern US: black bear (Ursus americanus), Rafinesque’s big-eared bat (Corynorhinus rafinesquii), and timber rattlesnake (Crotalus horridus). For each species, we mapped important habitat connections between core patches of habitat using three different modeling approaches (Connectivity Analysis Toolkit (CAT), Circuitscape, and Linkage Mapper) that incorporated three types of resistance layers (expert opinion, niche modeling, and empirical data for the black bear only). The result was 21 sets of important connections,...

This map contains historical habitat suitability for the greater sage-grouse (centrocercus urophasianus). In support of the Pacific Northwest Climate Change Vulnerability Assessment (www.climatevulnerability.org), we developed a method to model habitat suitability in which we built correlative climate suitability models for 366 terrestrial animal species at a relatively coarse spatial resolution for the entire North American continent, using species range maps and 23 bioclimatic variables. We then applied the models to both current and projected future climate data downscaled to a moderately fine resolution for western North America. We refined the resulting climate suitability projections by applying a filter that...

We systematically surveyed federal and state wildlife biologists, hydrological specialists, non-profit organizations, and working groups focused on beaver or wetland restoration in the western U.S. We focused primarily on contacting land managers from states containing some portion of the Great Basin, although many of the projects described in surveys fell outside of this watershed. Some land managers suggested colleagues who might be interested in participating in our study and these individuals were added to our list of contacts. We also performed a literature search using Google Scholar. We included only articles that were focused on primary research performed in the arid or semi-arid western US. We compiled...

Establishing connections among natural landscapes is the most frequently recommended strategy for adapting management of natural resources in response to climate change. The U.S. Northern Rockies still support a full suite of native wildlife, and survival of these populations depends on connected landscapes. Connected landscapes support current migration and dispersal as well as future shifts in species ranges that will be necessary for species to adapt to our changing climate. Working in partnership with state and federal resource managers and private land trusts, we sought to: 1) understand how future climate change may alter habitat composition of landscapes expected to serve as important connections for wildlife,...
