Closely related species often have similar traits and sometimes interact with the same species. A crucial problem in evolutionary ecology is therefore to understand how coevolving species diverge when
Antagonistic coevolution between hosts and parasites can lead to local adaptation (LA), such that parasite fitness is greatest in sympatric hosts (or vice versa). The magnitude of LA typically increas
Host traits, such as migratory behavior, could facilitate the dispersal of disease causing parasites, potentially leading to the transfer of infections both across geographic areas and between host sp
Social parasites exploit societies, rather than organisms, and rear their brood in social insect colonies at the expense of their hosts, triggering a coevolutionary process that may affect host social
One of the best known outcomes of coevolution between species is the rejection of mimetic parasite eggs by avian hosts, which has evolved to reduce costly cuckoo parasitism. How this behavioral adapta
