Publication Date



Rotifera; Itasca, Lake (Minn.); Microorganisms--Identification


Rotifers were collected from both the Littoral and Limnetic zones in Lake Itasca, Clearwater County, Minnesota, during two weeks in midsummer. In total, 82 species of rotifers were found, and 69 were identified to species. The littoral zone produced 67 species of rotifers, primarily associated with the aquatic macrophytes. While 35 species were collected in the limnetic zone, only 13 of them were restricted to that habitat. Species are listed by habitat and by type of plant on which they occurred.
