Climate Change and Habitat

Ecologists have long been interested in how patterns of species distribution and diversity shift with changing climates, a concern that has spiked as the reality of rapid global climate change becomes increasingly apparent. Knowing whether certain species are threatened by shifting climate patterns is important for planning management activities and predicting how ecosystem functions can change in the future.

Effect of latitude and Maxent threshold on projected percent climatic habitat loss by 2020, 2050, and 2080 for 35 plethodontid species currently found in the southern Appalachian region of the Coweeta LTER. Presented are percent suitable climatic habitat losses relative to current climate distribution model for two Maxent thresholds (‘strict’ = solid points with a solid regression line and dark grey 95% confidence bands; ‘liberal’ = hollow points with a dashed regression line and light grey 95% confidence bands). Darkest shading indicates regions of overlap between ‘strict’ and ‘liberal’ confidence bands
