Description

The watershed of southern Minnesota contains a variety of invertebrate species, some common and some endanger. It is important to identify these species, because their diversity could play a role in ecological stability and aid in the identification of changes in our environment. The purpose of this study was to begin a photographic catalog of invertebrates in the watershed. A dissecting light microscope was used to take initial micrographs of the organisms and their anatomy. The organisms were then identified. Smaller species were critical point dried, sputter coated, and viewed using scanning electron microscopy. With the aid of light and scanning electron microscopy, these invertebrates were identified and cataloged, which will provide a basis for future research.
