Dispersal evolution in the presence of Allee effects can speed up or slow down invasions
Successful invasions by sexually reproducing species depend on the ability of individuals to mate. Finding mates can be particularly challenging at low densities (a mate-finding Allee effect), a factor that is only implicitly accounted for by most invasion models, which typically assume asexual populations. Existing theory on singlesex populations suggests that dispersal evolution in the presence of amate-finding Allee effect slows invasions. Here we develop a two-sex model to determine how...[Show more]
