Land use and life history constrain adaptive genetic variation and reduce the capacity for climate change adaptation in turtles

Abstract Background Rapid anthropogenic climate change will require species to adapt to shifting environmental conditions, with successful adaptation dependent upon current patterns of genetic variation. While landscape genomic approaches allow for exploration of local adaptation in non-model system...
