Does gene flow aggravate or alleviate maladaptation to environmental stress in small populations?

SW Fitzpatrick, BN Reid - Evolutionary Applications, 2019 - Wiley Online Library
Environmental change can expose populations to unfamiliar stressors, and maladaptive
responses to those stressors may result in population declines or extirpation. Although gene …

Locally adapted traits maintained in the face of high gene flow

SW Fitzpatrick, JC Gerberich, JA Kronenberger… - Ecology …, 2015 - Wiley Online Library
Gene flow between phenotypically divergent populations can disrupt local adaptation or,
alternatively, may stimulate adaptive evolution by increasing genetic variation. We …

Genomic architecture controls multivariate adaptation to climate change

DE Terasaki Hart, IJ Wang - Global Change Biology, 2024 - Wiley Online Library
