Perspectives on the design and execution of DNA-based inventories for bears using hair sampling

Garth Mowat

I review 3 decades of experience involving DNA-based sampling for bear (Ursus spp.) inventories and provide some considerations for future users. Some of the less obvious suggestions follow. (1) Do not set baited sites in closed forest; rather, put them in places …

Testing the use of remote cameras to index body condition in brown and black bears

Garth Mowat, Troy Malish, Laura Smit, Kelly L. Forrester et autres

Body condition of large mammals is a highly labile parameter that is influenced by recent nutrition, the seasonal hormonal cycle, intrinsic traits such as age and reproductive status, and extrinsic stress factors such as predation risk, social dominance, or human disturbance. Body …

Grizzly Bear Diet in British Columbia at 1km resolution

Jonathan Van Elslander, Garth Mowat, Mathieu L. Bourbonnais, Oliver Holt et autres

Output maps of the proportion of different foods in the diet of male and female grizzly bears from Van Elslander et al. 2026. We estimated the proportion of vegetation, terrestrial meat, anadromous salmon, and non-anadromous kokanee salmon (“kokanee”) in individual bears’ diet …

Spatial variation in grizzly bear ( Ursus arctos ) dietary niche across British Columbia

Jonathan Van Elslander, Garth Mowat, Oliver Holt, Shelley Marshall et autres

Dietary niche variation can be a key driver of spatial variation in animals’ behaviour, population dynamics, and sensitivity to threats. Grizzly bears ( Ursus arctos Linnaeus, 1758) are a wide-ranging omnivorous mammal with enormous dietary flexibility. We used the stable isotope composition …

First known observations of migratory Army Cutworm Moth (Euxoa auxiliaris) in the southern Canadian Rocky Mountains

Erik J Peterson, Garth Mowat

Army Cutworm Moth (Euxoa auxiliaris) migrates long distances to mountain talus slopes where they aggregate in prodigious numbers over summer. Composed of ~70% lipid and ~25% protein at the height of summer, the moths attract Grizzly Bear (Ursus arctos horribilis) to talus …

Genetic connectivity of wolverines in western North America

Casey C. Day, Erin L. Landguth, Michael A. Sawaya, Anthony Paul Clevenger et autres

Abstract Wolverine distribution contracted along the southern periphery of its range in North America during the 19th and 20th centuries due primarily to human influences. This history, along with low densities, sensitivity to climate change, and concerns about connectivity among fragmented habitats …

Tissue Distribution and Toxicological Risk Assessment of Mercury and Other Elements in Northern Populations of Wolverine (Gulo gulo)

John Chételat, Thomas S. Jung, Malik Awan, Steven Baryluk et autres

Wolverines are facultative scavengers that feed near the top of terrestrial food chains. We characterized concentrations of mercury and other trace elements in tissues of wolverine from a broad geographic area, representing much of their contemporary distribution in northwestern North America. We …

How to find a wolverine: Factors affecting detection at wolverine (Gulo gulo) bait stations in western Canada

Andrea Kortello, Doris Hausleitner, Garth Mowat, Mirjam Barrueto et autres

Abstract High individual detection success enables precise estimates of density and the ability to monitor trends in abundance for wolverine and other low‐density species, information that is critical for the implementation and assessment of conservation measures. We evaluated a dataset that included …

Unsecured attractants, collisions, and high mortality strain coexistence between grizzly bears and people in the Elk Valley , southeast British Columbia

Clayton T. Lamb, Laura Smit, Garth Mowat, Bruce N. McLellan et autres

Abstract Historical persecution of grizzly bears in North America reduced the species range by 55%. Today, dedicated recovery efforts and shifting societal perceptions have supported the recovery and expansion of grizzly bear populations in many areas. With increasing overlap between people and …
