How are global patterns of faunal turnover expressed at regional scales? Evidence from the Upper Mississippian (Chesterian), Illinois Basin, USA
Linking biotic patterns across spatiotemporal scales provides a greater understanding of the processes that drive ecological and evolutionary change. Here, we examine how global patterns of biotic turnover are expressed in the structure of regional biotic gradients from the Illinois Basin (USA) during the late Paleozoic ice age (LPIA)— an interval noted for low global rates of taxonomic turnover.
