Community composition and Biogeography of northern Canadian Ephemeroptera, Plecoptera and Trichoptera
Climate change has a disproportionately effect on northern ecosystems. To measure this impact we need to understand the structure of northern communities and the influence of current and historical climate events. Insect of the orders Ephemeroptera, Plecoptera and Trichoptera (EPTs) are excellent su...
