Capitalizing on long-term experimental manipulations to understand and predict arctic terrestrial ecosystem responses to climate warming
chercheur principal: Grogan, Paul
Année(s) de permis: 2024 2023 2022 2021 2019
Résumé: The objectives of this research project are: 1) to determine the biogeochemical and ecological significance of our discovery that mesic tundra plant growth can be co-limited by nitrogen (N) and phosphorus (P); 2) to predict the likely impacts of not just climate change, but also declining caribou and other mammalian herbivory, on tundra deciduous and evergreen shrub abundances; and, 3) to evaluate...

Biogeochemical controls on the structure and functioning of low arctic ecosystems
chercheur principal: Grogan, Paul
Année(s) de permis: 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008
Résumé: The long-term goal of this research over the next 15-20 years is to substantially advance the understanding of how Canadian arctic tundra ecosystems function, and therefore how they are likely to be affected by these perturbations including climate change, and resource development and extraction. This research will work to answer the following questions: 1) Apart from birch, which other spec...
