The Secret Life of Rivers

Loading Events

Fans of fly fishing know that there are fish in the river… and that they eat “flies” that we dangle in front of them. Beyond fishing, we all need water for agriculture and for life itself. Obviously, we should care about the life of the river. So, what goes on in there? In fact, the ecology of rivers is complex, concealed, eye-opening, and will likely surprise you. This program by Dr. Jerry Freilich will explain how rivers work. How many organisms actually make up the riverine ecosystem? Where do they get their energy? And how many of them have you actually heard of? With an awareness of riverine ecology, you will understand why we have to protect running waters, and it will make you think about the effects of humans on the critters we love. Dr. Freilich is an aquatic ecologist who spent 25 years working for the National Park Service in six parks nationwide. Join the Sisters Science Club for this presentation of the Frontiers in Science lecture series. Social hour begins at 6 p.m. with light fare, beer, and wine available for purchase.
