Learning Activities

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.

Course Description
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.

Learning Outcomes

Upon completion of this course, the student will:

  1. Be able to describe the biotic and abiotic components of terrestrial, marine and fresh water environments.
  2. Be able to describe the flow of energy through ecosystems with reference to trophic levels and ecological efficiency.
  3. Understand the cycling of nutrients through ecosystems.
  4. Be able to demonstrate how an evolutionary ecology approach can be used to analyze life histories, sexual reproduction, sex ratios, mate choice, and social and altruistic behaviour.
  5. Be able to describe population structures, growth and the factors that limit the distribution and abundance of populations.
  6. Understand the various interspecific interactions including competition, predation, and mutualism and related evolutionary responses.
  7. Be able to describe community structure and the dynamics of community organization and change including the process of ecological succession.
  8. Be able to use general principles of ecology to analyze human impacts on ecosystems.
  9. Understand the principles of field sampling and be able to conduct field research using a variety of sampling techniques.
  10. Be able to interpret field results, perform simple statistics and write reports.
  11. Research and write a major report on an ecological topic, and communicate the results in an oral presentation and/or poster.
