Dispersal evolution in the presence of Allee effects can speed up or slow down invasions

Shaw, Allison; Kokko, Hanna


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]
