In this brief video, a biologist talks about the macroinvertebrates (typically aquatic insects) that form the basis of food webs in healthy streams. In Kentucky, these macroinvertebrates include mayflies, stoneflies, and caddis flies, all of which lay eggs and spend the early stages of their development in the water. Macroinvertebrates provide food for minnows and other small fish, which in turn become food for larger fish. In streams affected by acid mine drainage, these essential members of the food web are absent, with catastrophic results for the ecosystem.

Nice video clip of macroinvertebrates, but the tags need to be fixed. There were no baboons in the creek!
