Summary

Projected current and future potential distribution for the following vertebrate species: American Black Bear (Ursus americanus), American Marten (Martes americana), Canadian Lynx (Lynx canadensis), Lewis's Woodpecker (Melanerpes lewis), Mule Deer (Odocoileus hemionus), Tiger Salamander (Ambystoma tigrinum), Wolverine (Gulo gulo), based on correlative bioclimatic models and projected changes in vegetation biomes. Bioclimatic models were built using the Random Forest algorithm. Projected changes in vegetation were also modeled using the Random Forest algorithm but were produced by Rehfeldt et al. (2012). Projected current distribution is based on the average climate conditions for the years 1961-1990. Projected future distributions [...]

Purpose

Here, I combine species distribution models based on climate variables with simple biome-level habitat associations to produce models that can project future impacts on species distributions based on projected changes in climate and vegetation, with a reasonable level of accuracy. I then examine how refining the climate suitability models with these biomes associations affects the current suitability for each study species, and also compare differences in mean expansion and contraction of future species habitat suitability as simulated by two global circulation model projections and one emission scenario.
