Major areas of research in the quantitative plant ecology laboratory:

  • Forest ecology: biodiversity and stand dynamics of boreal and temperate rain forest.
  • Statistical ecology: application of fractals and multivariate analysis in biology.
  • Ethnobotany: studies of food, medicinal, and psychoactive plants.

Forestry research in west-central Manitoba focuses on stand dynamics and management of mixed-wood (hardwood-softwood) boreal forest. Research projects include: long-term dynamics of boreal mixed-wood stands; dynamics of post-harvest mortality along cut-block edges; growth and yield models for mixed-wood forest stands; and patterns and mechanisms of trembling aspen colonization. Forest research in coastal British Columbia focuses on biodiversity and the structural-compositional dynamics of old-growth temperate rain forest. Research in statistical ecology includes theoretical and practical approaches to multivariate data analysis in ecology, and the application of fractal theory to biological patterns and processes. Ethnobotanical research focuses on changes in the perception and utilization of food, medicinal and psychoactive plants over time, and on the ecology of medicinal plants native to Canada.

The quantitative plant ecology laboratory takes an integrative approach to higher learning, exposing students to a wide range of sub-disciplines within the ecological sciences. Particular emphasis is placed on the acquisition of strong numerical, statistical, computational and data analytic skills, from both theoretical and practical perspectives. Students also acquire skills in experimental design, field sampling methods, plant identification, geographical information systems, and the use of field and laboratory equipment. Our laboratory is a dynamic learning environment, emphasizing a cooperative approach to scholarly research based on sharing new ideas and challenging established paradigms.
