Course Description: BIOL 427 introduces the fundamental principles of how ecological systems function and how they are structured at organism, population and community levels. Concurrent enrolment in BIOL 427L (lab) and BIOL 492H (field) is required. These components are designed to introduce the scientific method of ecology through observation of patterns in nature, developing and testing hypotheses, synthesis and presentation of ecological research. The course provides exposure and experience in using the tools and techniques that ecologists use to gather and analyze data collected in the field.

Major Topics Covered
  • Physiological Ecology - the physiological mechanisms that plants and animals use in responding to their environment

  • Behavioral Ecology - the behavioral responses of animals to social and ecological factors
  • Ecology of Evolution - the role of the ecological environment in the evolution of traits of organisms
  • Demography and Life History - the lifetime patterns of growth, development and reproduction
  • Competition - the interactions among species sharing similar resources
  • Predation - the ecology of the interactions between predators and their prey
  • Plant-Herbivore Interactions - the ecolgy of the interactions between herbivores and their prey - plants
