THE ECOLOGY OF ENDANGERED BRANCHIOPODA IN ROCK POOL METACOMMUNITIES
Metacommunity ecology is a framework addressing interacting species that occur in a set of local communities linked by dispersal. Few studies have assessed endangered species distribution and abundance in this context. Endangered branchiopods, Branchinecta longiantenna and Branchinecta lynchi, are found throughout California in temporary ponds and wetlands, including rock pools. Little is known of their ecology and especially as it relates to their interactions with habitat features, water chemistry, and other species. We evaluated species’ patterns using three years of abiotic and biotic survey data of rock pools in Contra Costa and Alameda Counties, CA. Branchinecta lynchi was ubiquitous after inundation, while Branchinecta longiantenna emerged later and in fewer pools. Both populations were associated with pool volume, biodiversity (competitors and predators), and various water variables, and the relationships changed with time. Distribution patterns suggested B. lynchi was not limited by dispersal, while B. longiantenna was more limited by dispersal and environmental factors. These results highlight the importance of local and metacommunity dynamics for endangered species ecology.
