Using Aquatic Macroinvertebrates in Stream Bioassessment
out of 5 stars

Bioassessment is an evaluation of the biological condition of a waterbody using biological surveys and other direct measurements of resident living organisms. Aquatic macroinvertebrates are important indicators of stream health: they are relatively long-lived, differentially sensitive to...
Microhabitats and macroinvertebrates: Logjam influences on stream morphology and macroinvertebrate traits
01 Jan 2024 | Contributor(s): Carolyn Cummins, Adriana E. Martinez | doi:10.25334/ZVG7-2F67
Logjams are important hydrologic features that shape stream channel morphology and create habitat for organisms. In this lesson, students learn about and measure logjams in a wadeable stream and predict how logjams affect macroinvertebrate communities. This lesson is geared toward undergraduates,...
