The ecosystem approach to ecology treats organisms and the physical aspects of their environment as components of a single integrated system. Terrestrial ecosystem functioning is governed by interactions amongst animals, plants, and soil organisms, as well as exchanges of energy and resources with the atmosphere, soils, rocks, and aquatic environments. This advanced undergraduate level ecology course is focused on plant-soil interactions as being a fundamental determinant of the structure and functioning of terrestrial ecosystems around the world. As a group, we will attempt to synthesize recent advances arising from the ecosystem approach with established ecological theory to describe and explain ecosystem-level patterns and processes in the terrestrial environment. Since human activities are now having increasingly pervasive and dominant effects on natural ecosystems, the course will include an examination of global change issues in the context of landscape-level dynamics in space and time, and whole Earth biogeochemistry. In that context, the course content for 2014/15 in particular will be centered around the following thematic question:  What are the problems associated with current farm management practices in agroecosystems, and how can they be realistically and sustainably addressed?

Learning outcomes:
By the end of this course, the student should be able to
:

  1. Explain and evaluate the major concepts underlying terrestrial ecosystem ecology
  2. Describe and contrast the major processes and features that distinguish local terrestrial ecosystem-types
  3. Present a synthetic, logical and individualistic seminar on a fundamental issue in terrestrial ecosystem ecology
  4. Develop, conduct, analyse, and write a lab/field research study that addresses a student-inspired question in terrestrial ecosystem ecology.
