Jacquelyn Duke confirmed as plenary speaker.  Duke, Senior Lecturer in Biology at Baylor university, has focused her research on the hydrologic connections among streams (aquatic zone), stream bed and banks (hyporheic zone), and stream bank vegetation (riparian zone).  Duke’s research interests cover intermittent stream and forest ecology, and the highly productive and ecologically important riparian and hyporheic stream zones where much biogeochemical cycling takes place.  Duke’s life-long fascination with streams and the “dynamic” essence that allows them to go fro bone-dry creek beds to raging torrents overnight, translates to an enthusiasm for exploring biology and stream dynamics through the fresh eyes of her students.
