RBC researchers evaluate role of physiography in shaping stream fish metapopulation dynamics

Broadly distributed freshwater biota may face distinct conservation challenges because of physiographic gradients that elicit different responses to drivers of population dynamics across their range.  Working under this premise, RBC researchers Kit Wheeler, Mary Freeman, and Seth Wenger presented their preliminary findings at the recent annual meeting of the Southeastern Fishes Council in Jackson, MS.  The presentation, which serves as the basis for a forthcoming manuscript, identified apparent differences in stream fish colonization rates above and below the Fall Line that separates the Coastal Plain and upland physiographic regions, thereby illustrating the potential need for spatially variable freshwater conservation strategies.
