| Special Session - Metacommunities in Riverine Ecosystems | |||
| Substantial variation in dispersal exists between organisms that contribute to the structuring of ecological communities in space and time. The explicit incorporation of space into community ecology has been an important recent advance in our understanding of natural systems. Rather than view communities as isolated entities, we have begun to conceptualize them as assemblages determined by the relative strengths of stochastic regional effects (primarily dispersal-driven) and local environmental factors. Riverine ecosystems are common spatial features on the landscape, and the dendritic nature provides an ecologically interesting foundation to understand local versus regional effects on local community structure. In this session, our goal is to highlight ongoing research in riverine metacommunities, with special emphasis on riverine network structure. We will encourage submissions by researchers working across taxa (i.e., invertebrates, amphibians, fish) and in both natural and disturbed ecosystems. This broad perspective has the potential to highlight new questions in community ecology, in both basic and applied fields. | |||
