Regional changes in Cladocera (Branchiopoda, Crustacea) assemblages in subarctic (Yellowknife, Northwest Territories, Canada) lakes impacted by historic gold mining activities

Seasons of Change: Ecological Recovery From Legacy Arsenic Pollution in Rapidly Warming Subarctic Lakes

“…I am particularly interested in determining whether lakes closer to the Giant Mine site exhibit more significant plankton community assemblage changes compared to lakes which are farther away, and to compare community assemblages between the pre-mining, during, and post-mining time periods. Building from studies by Thienpont et al (2016) and Persaud et al (2021), I have been investigating the impacts of arsenic, specifically on Cladocera (Branchiopoda) communities. Cladocera are a group of crustacean zooplankton that preserve well in lake sediments and can be identified to species-level under compound microscopes.…”

Algal responses to metal(loid) pollution, urbanization, and climatic changes in subarctic lakes around Yellowknife, Canada

“…The sub-Arctic lakes around the City of Yellowknife (Northwest Territories, Canada; Figure 1) provide an important opportunity to assess the long-term biological responses to multiple environmental stressors, as this region: 1) has warmed by ~2. 7°C between 1942 and 2016; 2) was impacted for more than 50 years by one of the largest gold mining operations in Canada's North; and 3) has experienced major land-use changes in response to urban development (Jamieson 2014;Nasser et al 2016;Stewart et al 2018;Cheney et al 2020;Persaud et al 2021).…”
