University of Manitoba. Winnipeg, MB. Canada. Research InterestsMy broad area of interest is on the distribution of primary production in lakes, energy flow through aquatic foodwebs, and disruptions of established energy pathways by exotic species introductions. Much of my recent research has focused on modeling the growth dynamics of the common nuisance alga Cladophora glomerata, and determining the role of exotic dreissenid mussels in causing widespread Cladophora blooms throughout the lower Laurentian Great Lakes. I am currently conducting a meta-analysis investigating the implications of dreissenid invasions on the biogeochemistry, flora, and fauna of lakes and rivers. The analysis compares dreissenid effect sizes within lakes zones (littoral, pelagic, profundal), and between lakes, large rivers, and experiments (micro and mesocosms). ThesesHiggins, S. N. 2005.
