Among the Purdue courses that make extensive use of the Reserve every year are Ecology, Field Ecology and Conservation Biology. Student projects for these courses have investigated a wide variety of processes at the Reserve, using both experimental and observational approaches. These have included in vertebrate & invertebrate behavior, population dynamics, plant and animal community ecology, limnology, soils, climatology, biological diversity at several levels of organization, and conservation issues like invasion of natural communities by exotic species and pollution of aquatic habitats.
