Biotic interactions govern the distribution of coexisting ungulates in the Arctic Archipelago – A case for conservation planning by Deborah A. Jenkins, Nicolas Lecomte, Geoffrey Andrews, Glenn Yannic, James A. Schaefer

“…To test these ideas, we built distribution models for two large herbivores, muskoxen (Ovibos muschatus) and Peary caribou (Rangifer tarandus pearyi), systematically observed across a vast spatial extent – 65 islands spanning 800,000 km2 in the Canadian High Arctic. To test the ENH we fit SDMs with two sets of predictors: (1) abiotic only (i.e. topographic, climatic) and (2) abiotic + biotic (i.e. vegetation communities, distance-to-heterospecifics). …”

Biogeochemical evolution of ponded meltwater in a High Arctic subglacial tunnel by A. J. Dubnick, A. J. Dubnick, R. L. Spietz, B. D. Danielson, M. L. Skidmore, E. S. Boyd, D. Burgess, C. Dhoonmoon, M. Sharp

“…In this study, we extend our understanding of subglacial biogeochemistry and microbiology to include observations of a slushy pond of water that occupied a remnant meltwater channel beneath a polythermal glacier in the Canadian High Arctic over winter. The hydraulics and geochemistry of the system suggest that the pond water originated as late-season, ice-marginal runoff with less than <span class="inline-formula">∼15 <i>%</i></span> solute contribution from subglacial sources. …”
