Areas of Teaching and Research Interest: Aquatic ecology, Community ecology, Ichthyology, Biogeography, Evolution, and SystematicsThe general goal of Dr. Geheber's research is to build a better understanding of how and why patterns of organismal diversity arise and persist (or do not). Most of his time is spent working with fishes in aquatic systems, but he still tries to come up for a breath every now and again. Using freshwater fish communities as a study system, his aim is to uncover the mechanisms that govern community assembly (e.g., habitat filters, competition, predation, dispersal limitation). Furthermore, he has a long-standing interest in stream fish community structure dynamics across space, and through time.
