Summer programs in field biology were taught for many years at the station. The first director of the station, Dr. Walter F. Morofsky, was an entomologist with MSU. The library has a strong historical entomology collection. Early Bird Sanctuary research and teaching led to a good waterfowl collection. Once the year round research station was established in 1965, and the branch library was established, a strong research program in limnology was begun, which continues to this day. Currently, there are strong research programs in limnology, microbial ecology, plant ecology, agricultural ecology, fish ecology and vertebrate behavioral ecology.
The Gull Lake Library contains over 12,00 volumes, many of which are bound journal volumes. Nearly 150 current serial titles are received. The collection supports the research interests of KBS faculty, staff, students and visiting scientists in aquatic and terrestrial ecology, evolution, behavior and agro-ecology.
