The role of heterogenous bedrock in shaping topography and freshwater biodiversity of eastern North America
The mountain ranges of the central and southern United States have long been considered enigmatic, both for their sustained topographic relief and exceptional levels of freshwater biodiversity. In my talk, I will propose that the erosion through heterogeneous bedrock is an important mechanism for explaining the topography and freshwater biodiversity of these post-orogenic landscapes. As ancient geologic structures are exhumed through erosion, rocks with different chemical and physical properties are exposed at the surface of the landscape. This process does not only influence landscape dynamics, but also generates opportunities for speciation in freshwater fishes.
