Quantifying the probability of evolutionary rescue doi.org/10.32942/X2T...
Conceptual challenges in determining the probability of evolutionary rescue. Panels a and b: Population size trajectories of replicate populations exposed to environmental change (red lines – with evolution: grey lines – without evolution). If the environment does not improve (i.e., the mean fitness of the non-evolving ancestral population, w¯0, remains below 1), all populations go extinct without evolution (panel a). By contrast, if the environment improves after some time, lifting w¯0 above 1, some populations may survive even without evolution (panel b). However, adaptive evolution increases the chance of survival, and more populations persist. Panel c: Fraction of populations extinct at time t with and without evolution over time. Following the first environmental change (blue triangle), all evolving and non-evolving populations persist initially but eventually all non-evolving populations inevitably go extinct, while some evolving populations survive the change. However, the environment does not stay constant indefinitely and at the next environmental change (yellow triangle), more of the evolving populations go extinct. The figure is purely illustrative and not based on an actual model.
