Peary caribou (Rangifer tarandus pearyi)

A stochastic modelling framework to accommodate the inter-annual variability of habitat conditions for Peary caribou (Rangifer tarandus pearyi) populations. Kaluskar S, Johnson CA, Blukacz-Richards EA, Ouellet F, Kim DK, Arhonditsis G. Ecological Informatics. 2020 Mar

(Study period: 2000-2013 (July–October) . Study area: CAA – six distinct geographic island clusters (Banks, Axel Heiberg, Bathurst, Boothia, Melville and Mackenzie King), Study purpose: To assess the effects of climate change (increasing temperatures at 2x global trend, warming permafrost, reduction in summer sea-ice extent and in snow-cover extent and duration, thinning of ice shelves, higher rates of precipitation and more frequent extreme weather events causing excessive ice or deep/hard snowpack) on Peary caribou populations.
Spatiotemporal shifts in floral and faunal phenology, species overlap, and potential trophic mismatch are considered. Variables used are meteorological (surface snow melt (increased ice from fast melt making forage harder), precipitation (avoidance of wet habitats to forage), temperature (declines in sea ice affecting migration), wind speed (avoidance of areas where surface wind speeds are above 6.0 m s−1)), landscape features (fraction of rockland), and resource competition with muskoxen (Ovibos moschatus) (Muskox-supported wolf populations could increase predation rates on Peary caribou which also avoid muskox). A stochastic algorithm is used to recreate the population growth rates and identify locations, where Peary caribou could experience >10%, 25%, or 50% decrease relative to yr. 2000 population levels.)
