Maintaining Local Adaptation Is Key for Evolutionary Rescue and Long-Term Persistence of Populations Experiencing Habitat Loss and a Changing Environment.

ABSTRACT: The Anthropocene is marked by increased population extirpations and redistributions driven primarily by human-induced climate change and habitat loss. Habitat loss affects populations by removing occupiable area, which reduces carrying capacity through a reduction in resources, and fragmenting the landscape, which can reduce gene flow with potential consequences for adaptation to changing environmental conditions. Real patterns of habitat loss are non-random, often clustered in space and within a subset of environmental conditions (e.g., primarily in the valleys of a mountain-valley region). Spatial clustering of habitat loss can alter population connectivity, and environmental clustering can shift the mean as well as decrease the variance in environmental conditions available to populatio
