The science of Ecology investigates the distribution and abundance of organisms and their interactions with biotic and abiotic environments. This course will serve as an introduction to major areas of ecological study: population, community, and ecosystem ecology. Topics will include how populations are distributed in and limited by their environments, how organisms interact, how niches are determined, how ecosystems are structured, and how energy and nutrients flow through the biotic environment. A basic text in ecology as well as primary literature will guide lectures and discussions. We will include direct investigations of ecological phenomena in natural environments, and participants should be prepared for working in field conditions. Students will present their work in written and oral form.
