Aquatic Biology

biol 322 - Great lakes - Summer Session I

Ecology, identification, systematics, culture, and care of aquatic plants and animals, and adaptations to freshwater environments. Aquatic life is studied in the laboratory as well as in natural systems. Emphasis is placed on lakes, ponds, and streams, but wetlands (bogs, marshes, swamps) are also touched upon. The course assesses human impact on aquatic species and ecosystems, presents procedures for the stewardship of aquatic habitats with an emphasis on stream quality assessment, and introduces aquatic restoration ecology. Prerequisite: one year of general biology or one semester each of general zoology and general botany. (4 credits)
