A study of the descriptive and theoretical aspects of ecology and evolutionary biology. Lecture topics include the following: the process of evolution, ecosystem concepts, ecology of populations, physiological ecology, community ecology, and energy flow in ecosystems. Current ideas of evolutionary ecology will be integrated with the above topics to represent the unifying nature of these two major areas of biology. Laboratory periods will involve primarily field work in local communities. Emphasis will be on sampling of biological communities and analysis of ecological data. Prerequisite: BIOL 121. Counts on the biology major in the ecology group.
