Linkage Mapper uses GIS maps of core habitat areas and resistances to identify and map linkages between core areas. Each cell in a resistance map is attributed with a value reflecting the energetic cost, difficulty, or mortality risk of moving across that cell. Resistance values are typically determined by cell characteristics, such as land cover or housing density, combined with species-specific landscape resistance models. As animals move away from specific core areas, cost-weighted distance analyses produce maps of total movement resistance accumulated.The tool identifies adjacent (neighboring) core areas and create maps of least-cost corridors between them. It then mosaics the individual corridors to create...

288 adult and yearling female elk were captured on 22 Wyoming winter supplemental elk feedgrounds and monitored with GPS collars during the brucellosis risk period (February – July) from 2007 to 2015. There were 4 to 64 individual elk per feedground and each elk was monitored for 1 to 2 years. Here we provide the unique identifier for each individual elk, the GPS location of the elk, the date/time stamp of the GPS location, and the feedground the elk was captured on in Wyoming.

This dataset consists of point features identifying indices for potential passage rate at intersections with major transportation corridors for grizzly bear movements between the Greater Yellowstone Ecosystem (GYE) and Northern Continental Divide Ecosystem (NCDE) in the northwestern United States. Points are spaced at 300-meter intervals along major road corridors (interstates and U.S. highways) and are populated with values from Randomized Shortest Path (RSP) predictive raster models of potential male grizzly bear movement between the two ecosystems as described in Peck et al. 2016 (Potential paths for male-mediated gene flow to and from an isolated grizzly bear population, Ecosphere 8(10):e01969). RSP scores extracted...

The role of lynx dispersal in maintaining their populations at the landscape scale is unclear. A large proportion of local lynx populations are known to disperse following a snowshoe hare population crash, but whether these dispersal events contribute to the cyclic dynamics of neighboring populations is not well understood. If lynx dispersal does play an important role in lynx population dynamics then the conservation of dispersal corridors is critical to maintaining those dynamics. However, we currently have no information on the habitat requirements of dispersing lynx in relation to human land use, such as housing developments, road building, timber harvest, and mining, all of which could have a substantial impact...

Using data from 288 adult and yearling female elk that were captured on 22 winter supplemental elk feedgrounds in Wyoming and monitored with GPS collars from 2007 - 2015, we fit Step Selection Functions (SSFs) during the spring abortion season and then implemented a master equation approach to translate SSFs into predictions of daily elk distribution for five plausible winter weather scenarios (from a heavy snow, to an extreme winter drought year). We predicted elk abortion events by combining elk distributions with empirical estimates of daily abortion rates, spatially varying elk seroprevalence, and elk population counts. Here we provide 1) the adult and yearling female elk GPS collar data used to fit SSFs, 2)...
