To what extent will nitrogen limit Canadian boreal forest growth and the terrestrial carbon sink under global change?
chercheur principal: Kou-Giesbrecht, Sian
Année(s) de permis: 2025 2024
Résumé: This licence has been issued for the scientific research application No. 6084. The overarching objective of this research is to understand the extent to which nutrients will limit forest growth and terrestrial carbon sequestration in Canadian boreal forests and to improve how this is represented in climate change models. These climate change models can then be used to understand the impacts of ...


Controls on carbon and nutrient cycling in arctic tundra
chercheur principal: Grogan, Paul
Année(s) de permis: 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008
Résumé: 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
chercheur principal: Bliss, Lawrence
Année(s) de permis: 1994
Résumé: 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
chercheur principal: Cummins, W. Raymond
Année(s) de permis: 1991 1990 1989
Résumé: 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....
