B23A:
How Do Species Interactions, Connectivity, and the Environment Drive the Biodiversity and Assembly of Marine Metacommunities? I


Session ID#: 36913

Session Description:
Recent advances in our understanding of community assembly and biodiversity have been catalyzed by a recognition of the interplay between local and regional processes that contribute to metacommunity dynamics. We encourage studies that explore this interplay between environmental factors (resource availability and physical/chemical parameters), species interactions (e.g., competition, predation, symbiosis), and population connectivity (e.g., larval dispersal, spawning behavior, migration) in the context of biogeographic factors (microscale, mesoscale or basin-scale oceanographic features and/or dispersal barriers).

These processes are expected to influence community assembly, food web complexity, local diversity, and biogeography across a broad spectrum of communities (e.g., microbes to megafauna) and habitats (intertidal to deep sea). This session will showcase investigations of metacommunity dynamics across a range of spatial and temporal scales using a variety of experimental, observational, and modeling techniques. This approach has applications to predicting the effects of disturbance (natural or human-caused), identifying locations for protection (MPAs), and providing input to management of ocean resources (fisheries, mineral extraction).
