Description
Scope/Content: Abstract: Macroinvertebrates are commonly used to assess ecosystem health. Indices exist that evaluate habitat based on macroinvertebrate species and their occurrence in relation to water quality conditions. This study attempts to quantify a relationship between macroinvertebrate species composition (diversity and density) and geomorphologic changes (changes in habitat). The appearance of Diversity and Density, important measurement tools, of organisms indicate that an ecosystem is in a healthy, self-sustainable condition. It was found that geomorphologic change had a significant effect on macroinvertebrate diversity but not density. The study sets up the stage for future work that could create a macroinvertebrate index to evaluate ecosystem health based on changes in habitat.
