This course surveys the environmental factors, historical processes and ecological interactions that influence the distribution and abundance of plant species in the landscape. The class examines how plant communities are assembled and what processes influence their structure and diversity, including past and present human activities. We focus in particular on plant communities of the Northeast, using examples from the local landscape to illustrate key ecological concepts. Prerequisite: a course in plant biology, ecology or environmental science; statistics is recommended (e.g., MTH 220). BIO 365 must be taken concurrently. Enrollment limited to 20.
