High Resolution Mapping of Tundra Ecosystems on Victoria Island, Nunavut – Application of a Standardized Terrestrial Ecosystem Classification
Published 2019-09-01“…Here we develop and assess a process for obtaining a high-resolution ecosystem map of terrestrial ecological communities for the Intensive Monitoring Area (IMA) of the Canadian High Arctic Research Station (CHARS) in Cambridge Bay, Nunavut. The methodology is based on a standardized classification of tundra ecosystems, and will provide an ecological template for designing and implementing ecosystem research, long-term monitoring experiments, and for linking local scale research to regional scales using remote sensing tools and models. …”

The Effect of Freeze-Thaw Conditions on Arctic Soil Bacterial Communities
Published 2013-02-01“…Soil samples from three distinct sites, representing Canadian geographical low arctic, mid-arctic and high arctic soils were collected from Daring Lake, Alexandra Fjord and Cambridge Bay sampling sites, respectively. Laboratory-based experiments subjected the soils to multiple freeze-thaw cycles for 14 days based on field observations (0 °C to −10 °C for 12 h and −10 °C to 0 °C for 12 h) and the impact on the communities was assessed by phospholipid fatty acid (PLFA) methyl ester analysis and 16S ribosomal RNA gene sequencing. …”

Content, composition, and transfer of polyunsaturated fatty acids in an Arctic lake food web
Published 2022-01-01“…Here, we aimed to identify the main trophic pathways that support PUFA content in different fish species (mean 39.7 mg/g dry weight) used in the subsistence fishery of the Inuit community in Greiner Lake near Cambridge Bay (Nunavut, Canada). We used stable isotope and taxon‐specific PUFA stocks, to show that the lake food web was divided into distinctive pelagic and littoral benthic food webs and that different fish species obtained their PUFA from different sources within those food webs. …”
