Quantification of carbon fluxes and ecosystem characteristics in permafrost regions with a special focus on the impact of degradation processes
chercheur principal: Goeckede, Mathias
Année(s) de permis: 2023
Résumé: This licence has been issued for the scientific research application No. 5609. As part of the ERC-synergy project Q-Arctic, the research team plans to investigate biogeochemical and biogeophysical processes along transects following landscape gradients. Such gradients include natural variability within heterogeneous permafrost landscapes, such as: a transect from dry upload tundra into a lower ...


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: 2023 2022 2021 2019
Résumé: This licence has been issued for the scientific research application No. 5660. The objectives of this research project are: 1) To determine the biogeochemical and ecological significance of the discovery that mesic tundra plant growth can be co-limited by nitrogen and phosphorus. 2) To predict the likely impacts of not just climate change, but also declining caribou and other mammalian herbivor...


Carving out Climate Testimony: Inuit Youth, Wellness & Environmental Stewardship
chercheur principal: Bagelman, Jennifer
Année(s) de permis: 2024 2023 2022
Résumé: This licence has been issued for the scientific research application No.5433. This project addresses Arctic Ecosystems and their Impact on Inuit Communities. This project asks the two-fold question: how does climate change impact Inuit youth and what are the resilience factors that enhance well-being? The project is especially interested in innovative forms of adaptation key to continued surviv...


Community-led pilot project: Grizzly bear impact on large herbivore populations around Ulukhaktok
chercheur principal: Mavrot, Fabien PS
Année(s) de permis: 2022
Résumé: This licence has been issued for the scientific research application No.5353. This project aims at analyzing available archived Grizzly bear samples and collecting new Grizzly fecal samples as well as samples of animal and plant species that are possibly part of the diet of Grizzly bears around Ulukhaktok to create baseline knowledge on the number of resident Grizzly bear around Ulukhaktok and ...


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 Arctic is undoubtedly experiencing several major perturbations including climate change, and resource development and extraction (e.g. mining and pipeline construction) that are very likely to substantially affect the structure and functioning of its ecosystems. As a terrestrial ecosystem ecologist, the long-term goal of this research over the next 15-20 years is to substantially advance the u...


Soil microarthropod community responses to climate change
chercheur principal: Turnbull, Matthew S
Année(s) de permis: 2013
Résumé: The goal of the principal investigator is to assess the diversity of species and functional traits of microarthropods in the Canadian arctic. The Canada Tundra Ecosystem Carbon Study (CTECS) was selected as a research site because there have been running temperature, moisture, and nutrient addition treatments since 2004 with the goal of simulating climate change and predicting its effects on plant...


eSpace - Emergency Spatial Pre-SCAT for Arctic Coastal Ecosystems
chercheur principal: Duffe, Jason A
Année(s) de permis: 2012 2011 2010
Résumé: The objectives of this study are to: (1) Fly oblique helicopter videography for two study sites (i.e. the outer Mackenzie River Delta and Kugmallit Bay) and collect field data at various locations, as identified in the map provided. (2) Interpret helicopter videography and create an Environmental Sensitivity Index map. This will consist of a vector file of shoreline types, which will be drawn on...


Climate Change Impacts on Canadian Arctic Tundra Ecosystems - Metis Traditional Knowledge Study
chercheur principal: Grieve, Sheryl
Année(s) de permis: 2010 2009 2008 2007
Résumé: This project is part of a larger IPY study, CiCAT, that is looking at the effect of climate change on arctic tundra ecosystems. The researchers will be collecting Métis traditional knowledge on vegetation and terrain changes in the North Slave region. In addition, they will be collecting and commenting on the scientific methodology for the larger CiCAT project. They hope to provide an integral c...


Dall’s Sheep, Grizzly Bears and Wolves interactions in the Gwich’in Settlement Area: Traditional Knowledge and Climate Monitoring
chercheur principal: Lambert Koizumi, Catherine
Année(s) de permis: 2010 2008 2006
Résumé: The proposed project aims to: 1) update and expand important baseline information on Dall’s sheep, grizzly bears, and wolves, which will contribute to the revision of grizzly and Dall's sheep management plan; 2) understand the interactions between those species; 3) evaluate the effect of habitat features and climate on those interactions; and 4) document traditional knowledge about Dall's sheep, g...


ArcticNet Theme 1: Integrated Regional Impact Study of the Coastal Western Canadian Arctic
chercheur principal: Fortier, Martin
Année(s) de permis: 2013 2012 2011 2010 2009 2007 2006 2005 2004
Résumé: Warming of the Arctic is resulting in changes in sea ice formation, decay, and distribution which operate differently in the Eastern and Western Canadian Arctic. Short term sampling has been conducted, but this research is a long-term observation of the ocean, sea ice, atmosphere coupling. Sampling will be conducted at mooring stations, along the ship track, and at specific sampling stations, ...
