Major Drainages Tennessee Drainage -Toccoa River -Brasstown Cr. Oconee Drainage -Ben Burton ? Mobile Bay Basin Mississippi River

Biogeography -distributional histories of lineages and possible causal factors Vicariant event- ancestor had continuous distribution; subsequent isolation resulting in speciation Dispersal event- ancestor occupied one drainage; entered another through temporary connection where it subsequently speciates

Collection Questions Comparing Oconee drainage to Tennessee drainage collections, are the fish assemblages similar? What fish orders and families are notably present/absent? Why?

Based on our collections, what fish species might we expect to collect in the upper Coosa drainage? Draft a species list without using range maps in Fishes of Alabama. - habitat requirements

IBI, or Index of Biotic Integrity, is a method of calculating a numerical index of biological health for a particular stream site. IBI integrates scores for several indicators of ecosystem health, including: Diversity: numbers and kinds of fish present Community Structure: primarily based on feeding habits Fish Health: disease, parasites, presence of sensitive species Index of Biotic Integrity- Karr 1981
