“…The skulls were obtained from licensed fur trappers during the 2005-2006 to 2011-2012 fur trapping seasons (Oakley et al 2016), and held by the Yukon Department of Environment. Sex was determined by external examination (Robitaille et al 2012, Kukka andJung 2015).…”

Dental anomalies suggest an evolutionary trend in the dentition of wolverine (Gulo gulo)

In mammals, congenital dental anomalies likely represent an evolutionary trend in the reduction of teeth (oligodonty) from the primitive dental formula. We quantified variation in the number of teeth from 421 wolverine (Gulo gulo) from northwestern Canada, focusing on polydonty (additional teeth), congenital oligodonty, and tooth rotation (misalignment). We predicted that oligodonty may be an evolutionary consequence of a previously reported increase in size of carnassial teeth since the Pleistocene. We also predicted that wolverine with missing or rotated teeth had smaller dental arcades than those without these anomalies. Oligodonty was observed in 42 wolverines (10 %), with the most cases involving the P 1 or P 1 (56 %) and P 2 or P 2 (32 %). We observed rotated teeth in 43 % of wolverines; virtually all of the rotated teeth we observed were P 2 or P 2 . The frequency of oligodonty or rotated teeth was strikingly similar between the sexes. Both oligodonty and rotated teeth were observed more frequently in the mandibular than the maxillary toothrows. Most wolverine (67 %) with oligodonty were missing teeth unilaterally; in contrast, most animals with rotated teeth exhibited bilateralism (86 %). Condylobasal length and most measures of the dental arcade did not differ between wolverine with or without missing or rotated teeth; however, we found that skulls with missing or rotated teeth had narrower palate breadth ratios. Our data suggest that there may be an evolutionary trend in the loss of teeth at the anterior of the toothrows of wolverines, which may be a result of narrower dental arcades and larger carnassial teeth. Wolverine have a hypercarnivorous diet, and selection may be toward optimizing those teeth that contribute to securing and processing food (i.e., canine and carnassial teeth), and against those that likely do not contribute substantially to increasing fitness and survival, such as the P 1 /P 1 and P 2 /P 2 .

“…Information regarding pathogen and parasite disease potential to wolverines in the Arctic is insufficient to predict the possible impacts of such changes to the species. We therefore recommend continued monitoring of wolverine health using community-based initiatives in collaboration with hunters and trappers (Oakley et al 2016 ; Sharma et al 2019 ; Watson et al 2020 ) and study of physiological response to potential disease vectors. The connection between human and animal health in the Arctic and subarctic is increasingly recognized under the “One Health” framework (Ruscio et al 2015 ), yielding successful longitudinal monitoring efforts of wildlife health across diverse taxa (e.g., caribou, muskoxen, and ringed seal ( Phoca hispida ); Brook et al 2009 ; Tomaselli et al 2018 ; Harwood et al 2020 ); we advocate development of similar long-term efforts for wolverines.…”

Wolverines ( Gulo gulo ) occupy most of the globe’s Arctic tundra. Given the rapidly warming climate and expanding human activity in this biome, understanding wolverine ecology, and therefore the species’ vulnerability to such changes, is increasingly important for developing research priorities and effective management strategies. Here, we review and synthesize knowledge of wolverines in the Arctic using both Western science sources and available Indigenous Knowledge (IK) to improve our understanding of wolverine ecology in the Arctic and better predict the species’ susceptibility to change. To accomplish this, we update the pan-Arctic distribution map of wolverines to account for recent observations and then discuss resulting inference and uncertainties. We use these patterns to contextualize and discuss potential underlying drivers of distribution and population dynamics, drawing upon knowledge of food habits, habitat associations, and harvest, as well as studies of wolverine ecology elsewhere. We then identify four broad areas to prioritize conservation and research efforts: (1) Monitoring trends in population abundance, demographics, and distribution and the drivers thereof, (2) Evaluating and predicting wolverines’ responses to ongoing climate change, particularly the consequences of reduced snow and sea ice, and shifts in prey availability, (3) Understanding wolverines’ response to human development, including the possible impact of wintertime over-snow travel and seismic testing to reproductive denning, as well as vulnerability to hunting and trapping associated with increased human access, and (4) Ensuring that current and future harvest are sustainable.
