Diet and landscape characteristics drive spatial patterns of mercury accumulation in a high-latitude terrestrial carnivore. by Inés Peraza, John Chételat, Murray Richardson, Thomas S Jung, Malik Awan, Steve Baryluk, Ashu Dastoor, William Harrower, Piia M Kukka, Christine McClelland, Garth Mowat, Nicolas Pelletier, Christine Rodford, Andrei Ryjkov

“…Total mercury concentrations in wolverine muscle ranged >2 orders of magnitude from 0.01 to 5.72 μg/g dry weight and varied geographically, with the highest concentrations in the Northwest Territories followed by Nunavut and Yukon. Regression models at both spatial scales indicated diet (based on nitrogen stable isotope ratios) was the strongest explanatory variable of mercury concentrations in wolverine, with smaller though statistically significant contributions from landscape variables (soil organic carbon, percent cover of wet area, percent cover of perennial snow-ice) and distance to the Arctic Ocean coast. …”

Genetic Diversity and Dispersal of <i>Aspergillus fumigatus</i> in Arctic Soils by Gregory A. Korfanty, Mykaelah Dixon, Haoran Jia, Heather Yoell, Jianping Xu

“…In this study, we isolated 32 and 52 <i>A. fumigatus</i> strains from soils in Iceland and the Northwest Territories of Canada (NWT), respectively. These isolates were genotyped at nine microsatellite loci and the genotypes were compared with each other and with those in other parts of the world. …”

Permafrost thaw induced drying of wetlands at Scotty Creek, NWT, Canada by K M Haynes, R F Connon, W L Quinton

“…Water levels on a permafrost plateau, channel fen, and isolated and connected bogs were monitored from 2003–2017 in the Scotty Creek watershed, Northwest Territories. The water level in the channel fen did not significantly change over the period of study, sustained by inputs from the increasingly-connected network of bogs as permafrost barriers thawed. …”

Using TLS-Measured Tree Attributes to Estimate Aboveground Biomass in Small Black Spruce Trees by Steven Wagers, Guillermo Castilla, Michelle Filiatrault, G. Arturo Sanchez-Azofeifa

“…<i>Materials and Methods</i>: The study focusses on small black spruce trees (<5 m) located in peatland ecosystems of the Taiga Plains Ecozone in the Northwest Territories, Canada. Black spruce growing in peatlands are often stunted when compared to upland black spruce and having models specific to them would allow for more precise biomass estimates. …”

Feather isotopes ( δ 2 H f ) and morphometrics reveal population-specific migration patterns of the Blackpoll Warbler ( Setophaga striata ) by Erica H Dunn, Kevin J Kardynal, Kristen M Covino, Sara R Morris, Rebecca L Holberton, Keith A. Hobson

“…These birds travel northward from the eastern Gulf of Mexico to Canada east of the Great Lakes before turning westward to reach their final destination between northwestern Ontario and eastern portions of the Northwest Territories. Many birds sampled at Great Lakes sites prior to 2010, but not thereafter, had δ 2 H f and wing-length characteristics expected of breeding range in eastern Canada, suggesting differential rates of population change among regions. …”

Application of GNSS Interferometric Reflectometry for the Estimation of Lake Ice Thickness by Yusof Ghiasi, Claude R. Duguay, Justin Murfitt, Joost J. van der Sanden, Aaron Thompson, Hugo Drouin, Christian Prévost

“…The proof of concept is demonstrated through the analysis of Signal-to-Noise Ratio (SNR) time series extracted from Global Positioning System (GPS) constellation L1 band raw data acquired between 8 and 22 March (2017 and 2019) at 14 lake ice sites located in the Northwest Territories, Canada. Dominant frequencies are extracted using Least Squares Harmonic Estimation (LS-HE) for the retrieval of ice thickness. …”

Investigation of incidence and geographic distribution of gliomas in Canada from 1992 to 2010: a national population-based study highlighting the importance of exposure to airport... by Xinyu Ji, Akram Alakel, Feras M. Ghazawi, Matthew Tsang, Andrei Zubarev, Oliver J. Lasry, Ivan V. Litvinov, Ivan V. Litvinov, Ivan V. Litvinov

“…Significantly lower crude incidence of glioma was found in Nunavut, Northwest Territories, Ontario, and Alberta. A putative regional clustering of gliomas was observed, with higher incidence rates in postal code areas correlating with industrial activity related to airport operations.ConclusionThis study describes the geographic distribution of the glioma disease burden and, potentially, identifies industrial activity related to airport operations as potentially being associated with higher incidence of this cancer.…”
