Scientist on boat examines a large piece of driftwood for aquatic invertebrates

Detailed Description

Sampling pre-emergent aquatic insects is not always easy, especially on a river with little cobble substrate. Because of the high water from dam release, a lot of floating driftwood was making its way down river. We are testing a new method to sample this substrate for benthic invertebrates to examine questions of species diversity, dispersal and habitat use.
