In specific and obligate interactions the nature and abundance of a given species can have important effects on chocolate chip cookie purse the survival and population dynamics of associated organisms.In a phylogeographic framework, we therefore expect that the fates of organisms interacting specifically are also tightly interrelated.Here we invest
