This dataset represents a species known range extent for Wolverine (Gulo gulo) within the conterminous United States (CONUS) based on 2001 ground conditions. This range map was created by attributing sub-watershed polygons with information of a species' presence, origin, seasonal and reproductive use. See Gap Analysis Project Species Range Maps for more information regarding data creation and user constraints. For species specific range information, see the attached Range data.

Anthropogenic impacts such as habitat conversion and fragmentation, in combination with predator control and fur trapping, are responsible for substantial reductions in the ranges of many carnivores worldwide. The wolverine (Gulo gulo) is classified as vulnerable throughout the Holarctic Region by the International Union for Conservation of Nature and Natural Resources, is designated as endangered in eastern Canada, and has been petitioned twice for listing with the United States Fish and Wildlife Service. We examined genetic structure across populations in northwestern North America by using mtDNA sequences of the left domain of control region and the complete cytochrome-b gene (Cytb). Nucleotide diversity (π)...

Context: Wolverines (Gulo gulo) are harvested for fur in northern Canada; however, the impacts of harvest are poorly known. Additionally, wolverine population data are largely absent for much of their northern range. Demographic data collected from harvested wolverines provide information on the vulnerability and variability of different sex and age cohorts to harvest, which, in turn, may have implications for harvest sustainability.Aims: We examined the temporal variability of different sex and age cohorts in wolverine harvest among years, and within the harvest season, in Yukon, Canada. We also examined the pregnancy status of female wolverines in relation to the harvest date, so as to evaluate the impact of the...
The wolverine (Gulo gulo), largest terrestrial member of the weasel family, is perhaps one of the rarest and least-studied carnivores in North America. Resembling a short, stocky bear, this animal sports a distinctive bushy tail, small ears and eyes, and semi-retractable claws for climbing and digging. Adult females weigh in the range of 8-12 kg, and males weigh some 50% more. Although they are active during the day, wolverines are primarily nocturnal. Their average lifespan is ten years and they have been known to live as long as 18.
The Crown of the Continent Landscape Analysis/Ecological Indicators Project is focused on issues of (i) landscape-scale transboundary GIS data acquisition, integration, and synthesis across the Crown of the Continent Ecosystem; (ii) the production of large-area habitat and connectivity models for select wildlife species that are key indicators of terrestrial and aquatic integrity; and (iii) the dissemination of knowledge, data products, and geospatial tools to managers and collaborators through data portals and outreach programs designed to support effective conservation delivery. Specific activities this year will involve (i) the development of CCE-wide models of grizzly bear (Ursus arctos), wolverine (Gulo gulo),...

The transboundary region of Washington and British Columbia (Fig. 1) is important for the conservation of many wildlife species. Some species of conservation concern, such as wolverine (Gulo gulo) and Canada lynx (Lynx canadensis), have home ranges that span the international border. Other species depend on the region for seasonal habitat. All regional wildlife species will require a connected network of habitats spanning the border as they adjust their ranges to meet life history requirements under future changes to climate and land-use. Previous analyses have identified numerous areas within the region where habitat connectivity has been disrupted by human activities (Gaines et al. 2001; Singleton et al. 2002,...
The Crown Managers Partnership (CMP) proposes to utilize our Landscape Analysis data, corresponding geospatial ecological metrics, and our collaborative management constituency to address invasive species, land use change, and subsequent impacts to targeted transboundary species within the Crown of the Continent Ecosystem (CCE)1. In the coming year, we propose to take a crucial step with our Landscape Analysis and utilize the synthesized geo-spatial data for two distinct objectives; i) Develop coordinated cross-jurisdictional management outcomes for a suite of transboundary species using occupancy and abundance models for grizzly bear (Ursus arctos), wolverine (Gulo gulo), cutthroat trout (Salmo clarki), and bull...

Understanding a species’ behavioral response to rapid environmental change is an ongoing challenge in modern conservation. Anthropogenic landscape modification, or “human footprint,” is well documented as a central cause of large mammal decline and range contractions where the proximal mechanisms of decline are often contentious. Direct mortality is an obvious cause; alternatively, human‐modified landscapes perceived as unsuitable by some species may contribute to shifts in space use through preferential habitat selection. A useful approach to tease these effects apart is to determine whether behaviors potentially associated with risk vary with human footprint. We hypothesized wolverine (Gulo gulo) behaviors vary...

Interglacial-glacial cycles of the Quaternary are widely recognized in shaping phylogeographic structure. Patterns from cold adapted species can be especially informative - in particular, uncovering additional glacial refugia, identifying likely recolonization patterns, and increasing our understanding of species' responses to climate change. We investigated phylogenetic structure of the wolverine, a wide-ranging cold adapted carnivore, using a 318 bp of the mitochondrial DNA control region for 983 wolverines (n = 209 this study, n = 774 from GenBank) from across their full Holarctic distribution. Bayesian phylogenetic tree reconstruction and the distribution of observed pairwise haplotype differences (mismatch...
