Hart and Wart (2023) investigate the role of genomic architecture in adaptive gene flow and in-situ adaption. This is often overlooked in the context of climate change. Using simulation techniques, they were able to model microevolutionary responses of two independent traits to environmental change. Climate-tracking gene flow was constrained in genetic scenarios with high polygenicity (the number of loci underlying a trait) and low linkage (the rate of recombination between these loci). Further evaluating the genetic conditions that allow for microevolution to climate change will be an important step in understanding climate vulnerability and may be informative in future management efforts.
