A study of the interaction of living organisms with biotic and abiotic aspects of their environment. Population, community and ecosystem ecology are examined along with a consideration of topics in evolutionary ecology like life history theory, mating systems and social behaviour. The course also investigates conservation of biological diversity and the impact of human activities on natural systems.

- Global warming
14. Ecological field and lab techniques
- Design of manipulative field and lab experiments
- Habitat characterization (e.g. stream, forest, meadow, salt marsh)
- Plant/animal identification
Techniques may include:
- Quadrat/point quarter sampling
- Transect sampling
- Random/systematic sampling
Methods of Instruction
This course involves 4 hours per week of classroom instruction and four hours per week of laboratory activity or field trip. Classroom work will include lectures and tutorials, and is integrated with textbook and scientific journal readings. Field trips and laboratory activities complement and enhance understanding of the theory content of the course.
Means of Assessment
Evaluation will be carried out in accordance with Douglas College policy. The instructor will present a written course outline with specific evaluation criteria at the beginning of the semester. Evaluation will be based on the following:
|Class Tests & Assignments
|Lab & Field Trip Reports
Upon completion of this course, the student wil be able to:
- Characterize and distinguish biotic and abiotic components of terrestrial, marine and fresh water environments.
- Employ an evolutionary ecology approach to analyze life histories, sexual reproduction, sex ratios, mate choice, and social and altruistic behaviour.
- Describe population structures and growth, and identify the factors that limit the distribution and abundance of populations.
- Describe community structure and the dynamics of community organization and change including the process of ecological succession.
- Illustrate the flow of energy through ecosystems with reference to trophic levels and ecological efficiency.
- Illustrate the cycling of nutrients through ecosystems, then compare and contrast ecosystem energy flow with nutrient flow.
- Compare and contrast the effects of competition, predation, and mutualism on individual life histories and behaviour, population growth, community structure and ecosystem function.
- Analyze human impacts on ecosystems using the general principles of ecology.
- Describe the principles of field sampling and conduct field research using a variety of sampling techniques.
- Interpret field results, perform simple statistics and write reports.
- Research an ecological topic and communicate the results in a written report, oral presentation and/or poster.
