A functional analysis of freshwater ecosystems, with emphasis on lakes. Lectures cover water chemistry; the physical structure of lakes; the different ways that algae, zooplankton, benthic invertebrates, and fish have evolved to succeed in these habitats and interact with one another; and the impact of humans on freshwater systems. Students must be available to participate in a 1-day field trip to visit aquatic habitats further from campus on a weekend in either late September or early October. Students not available for a 1-day weekend trip should not register for this course. Ancillary fees for the course apply. Please check the Departmental website for full details.
