The effect of habitat choice on evolutionary rescue in subdivided populations

Abstract: Evolutionary rescue is the process by which a declining population successfully adapts genetically to avoid extinction. In a structured environment that deteriorates patch by patch, dispersal can substantially alter the chances of evolutionary rescue of a wild-type population not viable in deteriorated patches. Here, we investigate the effect of different dispersal schemes and intensities on the probability of successful establishment of a mutant population adapted to the deteriorated environment. We find that… Show more

“…The case of not-too-large populations is practically very important because real populations tend to have complex structures ( van Marle et al 2007 ), and competition is local, which decreases their effective size, at least on timescales shorter than those of large-scale migrations and/or mixing. Accordingly, an exciting extension would be to consider the impact of spatial structure ( Bitbol and Schwab 2014 ; Cooper et al 2015 ; Nahum et al 2015 ) on evolutionary rescue ( Uecker et al 2014 ; Czuppon et al 2019 ) in a gradually deteriorating environment. In cases where one aims to avoid rescue, our results entail that environment changes should be made as fast as possible.…”

“…We take the same point of inflection θ for W and S, as it marks the midst of the environmental transition. Conversely, 72 we allow different Hill coefficients n and m, reflecting a different sensitivity of W and S individuals to environmental 73 change (see Fig. 1A).…”
