Ecology, EES-152, 4 credits
**Offered Every Fall Semester**
Course description
The study of relationships among organisms and their physical environment. Ecology of individual organisms, populations, communities, ecosystems, landscapes, and the biosphere. Topics include organism adaptations and natural selection, life histories, population growth and dynamics, species interactions, energy flow, nutrient cycling, and ecological impacts of human activities. Field-based laboratories focus on the quantitative study of biological populations and communities. Lectures, field-based laboratories, and applied activities.
Course objectives
- Gain an appreciation of relationships between organisms and their environment at the individual, population, community, and ecosystem levels.
- Understand the various approaches and methods that ecologists use to study these relationships at a variety of spatial and temporal scales, including spatial scales ranging from individual organisms to the biosphere, and temporal scales ranging from hours to millennia.
- Become familiar with the application of ecological principles to the management and restoration of ecosystems.
Course structure
The course uses a combination of traditional lectures, discussions, and case-study activities utilizing figures and datasets culled from the primary literature. The lab portion is dominated by field exercises, including a multi-week investigation of forest communities, population ecology utilizing a range of sampling techniques, bioindication using river macroinvertebrate communities, and a tree demography project. Several shorter projects and one weekend trip expose students to the structure and function of a range of ecosystems (e.g., coastal dunes, rivers, wetlands). Both the field and laboratory activities in the course are designed to develop analytical and quantitative skills (e.g., regression, basic statistics, mathematical modeling) as well as collaborative learning.
