Objective(s): to measure nitrate reductase activity, and alternative pathway activity in plants growing along a natural nitrate-ammonium gradient in Truelove Lowland, Devon Island

Project Description: Professor Cummins and his team will estimate potential productivity of plants in northern ecosystems and will investigate further the exceptionally high rate of respiration and alternative pathway respiration which they have discovered in arctic plants. They will use nitrate and ammonium electrodes to survey the levels of available nitrogen in wet and dry meadows on Devon
