Summary: The goal of this research over the next five years is to substantially advance the understanding of how Canadian arctic tundra ecosystems function, and therefore how they are likely to be affected by perturbations such as climate change, resource development and extraction, and atmospheric pollution. Specifically, the research team will focus on the impacts on vegetation due to warmer summer tempe...

Summary: We seek to better understand how ecosystems develop in the high arctic following retreat of ice caps. This includes studies of soil development and the influence that rocks play in this as well as studying the development of block crusts of organisms that form on the soil surface. We will also try to understand the role these crusts play in fixing nitrogen and influencing the development of flower...

Principal Investigator: Graham, Mark S
Licensed Year(s): 1992
Summary: The researcher and his team will use several species of planktonic and benthic invertebrates from Lancaster Sound region to evaluate the metabolic cost of making a living in the Arctic. Oxygen consumption techniques will be used as a metabolic indicy. Trophic status of specimens will be evaluated later by stable isotope analysis....

Principal Investigator: Cummins, W. Raymond
Licensed Year(s): 1991 1990 1989
Summary: The Researcher and team will continue to collect information about repiration rates and growth rates in Arctic plants. They will confirm that Arctic plants have low rates of nitrate reductase activity and will determine if relationships exist between rates of respiration, photosynthesis and nitrogen reduction in these plants....

Principal Investigator: Lewis, Martin
Licensed Year(s): 1982
Summary: To undertake a study of the rate which some Arctic plants acquire nitrogen. Plants will be collected and analyzed for the amount of nitrogen they contain....

Principal Investigator: Nosko, Peter
Licensed Year(s): 1980
Summary: To undertake a study of the nitrogen decomposition ability of a large quantity of bacteria located around the roots of High Arctic plants. This phenomenon may explain plant growth in polar desert regions....
