This course has a mandatory, four-day supervised lab component in Athabasca. See BIOL 345 lab resources on the Science and Technology website.
Overview
Ecology, as a branch of biology, is the study of the interactions of organisms with their environments. This course covers experimentation and models, relationships between organisms and their abiotic environments, population ecology and various symbiotic relationships, community ecology, ecosystem energetics and biogeochemical cycles, as well as aquatic and terrestrial biomes.

Learning outcomes
Upon completion of BIOL 345, you will be able to
explain how the physical environment (water, climate, soils, light and nutrients) shapes ecological processes.
describe the fundamental role of plant and animal adaptations for ecology.
define and apply the population concept when describing population growth and life history.
describe the concepts of competition, predation, parasitism and mutualism in the context of community ecology.
define, with examples, major aspects of both community structure and community dynamics.
explain the concept of landscapes in ecology.
describe major aspects of ecosystem ecology, including energetics, decomposition and biogeochemical cycles.
describe the earth’s major aquatic and terrestrial biomes.
explain the major concepts of climate change ecology.
Evaluation
To receive credit for BIOL 345, you must obtain a course composite grade of at least D (50 percent) as well as 50 percent on the examination, and 50 percent on the lab assignment. The weighting of the composite grade is as follows:

The final examination for this course must be requested in advance and written under the supervision of an AU-approved exam invigilator. Invigilators include either ProctorU or an approved in-person invigilation centre that can accommodate online exams. Students are responsible for payment of any invigilation fees. Information on exam request deadlines, invigilators, and other exam-related questions, can be found at the Exams and grades section of the Calendar.
To learn more about assignments and examinations, please refer to Athabasca University’s online Calendar.
Materials
Smith, T. M. and Smith, R. L. 2015. Elements of Ecology, 9th ed. San Francisco: Pearson Education. (eText)
The first three home labs require some materials that you must supply. If you do not own these materials already, these materials should cost less than $30. The assignments and examination must be completed within your registration period (normally six months). However, the Field Ecology Workshop can be done up to 14 months after your initial registration. The Field Ecology Workshop (FEW) is compulsory. It consists of four days of field and laboratory work. It will be held in the summer at Athabasca University's headquarters in Athabasca, Alberta.
For up-to-date information regarding the Field Ecology Workshop dates, see lab schedule or contact the science lab coordinator at fst_success@athabascau.ca.
Athabasca University reserves the right to amend course outlines occasionally and without notice. Courses offered by other delivery methods may vary from their individualized study counterparts.
