Controls on carbon and nutrient cycling in arctic tundra
Principal Investigator: Grogan, Paul
Licensed Year(s): 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008
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...


Constraints To Ecosystem Development in High Arctic Polar Deserts
Principal Investigator: Bliss, Lawrence
Licensed Year(s): 1994
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...


To Study Control of Metabolic Rates in Arctic Plants
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....


Licence #1791
Principal Investigator: Schulten, R.
