Prof. Bill Fagan - River Ecology: How Branching Geometry Influences Connectivity, Extinction Risk and Biogeography
Description:
Riverine landscapes differ in fundamental ways from terrestrial ones. Intrinsic effects of configuration, directional biases, transient connectivity, and opportunities for 'out of network' movement may all lead to inherently asymmetrical opportunities for connections among parts of a riverine landscape thereby influencing ecological processes and biogeographic patterns. This 'alternative geometry' of riverine networks provides excellent opportunities for scientists to explore how network connectivity shapes habitat occupancy, metacommunity dynamics, and biogeographic patterns. I will discuss here how human modifications to the spatial characteristics of river systems influence ecological dynamics and biogeographic patterns.
