Biology 3061F/5261F Communities and Ecosystems

Summary: 1
Biology 3061F/5261F
Communities and Ecosystems
Professor Pat Lane
3 Hours of Lecture/Week

Class Description

Ecosystems are communities of living organisms and their physicalchemical environments
that interact together within the biosphere. With few exceptions, all life, including human
life, exists within ecosystems. The class is divided into two parts. In the first part of the
course, there is an introduction to ecosystems including their definition, history, and the
theory of community structure and stability. Topics include: complex systems, general
systems theory, pairwise and multiple species interactions, the community matrix,
descriptors of natural communities, ecological stability theory, food webs and systems
theory. Several types of modeling approaches to ecosystems will be explored and compared
including conceptual, mathematical and statistical examples. Emphasis will also be given to
the community structure controversy and recent evidence for and against the notion that
communities are highly structured.
