How does proximity to roadways impact water quality and invertebrates in Arctic lakes?
chercheur principal: Gray, Derek K
Année(s) de permis: 2021
Résumé: This licence has been issued for the scientific research application No.4966. The purpose of the proposed project is to improve the understanding of the effects of road development on lakes in Canada’s north. To achieve this purpose, the research team will pursue two objectives: 1) to determine if changes in water quality caused by road dust affects invertebrate communities (bugs and waterfleas...

A monitoring program for Frame Lake
chercheur principal: Gray, Derek K
Année(s) de permis: 2020 2019
Résumé: This licence has been issued for the scientific research application No.4640. The research team is planning to establish a long-term monitoring program in Frame Lake to monitor water quality, zooplankton and benthic invertebrates. Water quality probes will be set up at a central monitoring point on the lake. A buoy will be anchored to the lake bottom and the probes will be attached to the bu...

Impact of ferry landings on water quality and traditional fish harvesting in the Mackenzie and Peel Rivers
chercheur principal: Gray, Derek K
Année(s) de permis: 2019 2018
Résumé: Fishing is an important part of the Gwich’in way of life. Concerns in the Gwich’in communities of Fort McPherson and Tsiigehtchic have arisen with regards to the use of granular material in ferry landings. Anthropogenic sediment from ferry landings has the potential to alter river ecology downstream thus impacting valuable fish habitat. The objectives of this research project are to determine ...

How will fish communities in Gwich’in and Inuvialuit lakes respond to climate change?
chercheur principal: Gray, Derek K
Année(s) de permis: 2019 2018 2017
Résumé: The purpose of this project is to obtain baseline data for fish communities in Gwich’in Settlement Area (GSA) lakes and use these data to predict future changes in fish communities caused by climate change. Specific objectives are to: 1) develop a baseline data set for fish populations, fish habitat, water quality, and water temperature for small and medium sized lakes within the Mackenzie ...

Predicting climate-driven changes in water quality and biological communities in Gwich'in lakes
chercheur principal: Gray, Derek K
Année(s) de permis: 2017
Résumé: Zooplankton play a key role in aquatic food webs, providing a conduit for the movement of energy between primary producers (algae) and larger organisms such as macroinvertebrates and fish. Therefore, elucidating the impact of permafrost melting on zooplankton is key to gaining a broader understanding of climate change on aquatic ecosystems in Canada’s north. Objectives of this proposed researc...
