2016 Ecology Lecture 4

HHMI's Holiday Lectures on Science show

Summary: Many rivers of the world have vast seasonal changes in flow rates. Dr. Mary Power leads us in an exploration of Northern California’s Eel River and how the community of herbivores and predators is affected by changes in river flow. Drought years with no winter floods generate a very different ecosystem compared to years with floods. Human-induced water shortage will also have a drastic detrimental effect on river ecology.
