Micro‐habitat selection by boreal woodland caribou improves access to food

Wildlife Biology, EarlyView.
Bio‐logging sensors attached to radiotelemetry receivers have great potential to transform our understanding of the ecological, physiological, and energetic constraints that shape patterns of wildlife movement under field conditions.

Inferring the rules of social interaction in migrating caribou [PDF]

Philosophical Transactions of the Royal Society B: Biological Sciences, 2018
Social interactions are a significant factor that influence the decision-making of species ranging from humans to bacteria. In the context of animal migration, social interactions may lead to improved decision-making, greater ability to respond to ...

Uncertainty during migration: the role of predictable resources in unpredictable conditions in determining movement in Woodland Caribou (Rangifer tarandus)

Journal of Mammalogy, 2023
Environmental and climatic variation drive animal migration. Animals must adjust their behavioral strategies, for example, habitat selection, to match best variation in resources whose value likely varies with conditions such as weather.

TRYPANOSOMIASIS IN WOODLAND CARIBOU OF NORTHERN ALBERTA

Journal of Wildlife Diseases, 1997
Blood was collected from 49 adult woodland caribou (Rangifer tarandus caribou) captured in northern Alberta, Canada, from October to February, 1991 to 1992 and 1992 to 1993. Smears of the buffy coat layer and of whole blood were examined microscopically for Trypanosoma sp., and blood was cultured for latent parasites.

Declines in Populations of Woodland Caribou

The Journal of Wildlife Management, 2003
We summarize the demography of woodland caribou (Rangifer tarandus caribou) inhabiting 6 ranges in northeast Alberta, Canada, from 1993 to 2002. Among ranges, mean annual survival of radiomarked adult females averaged 0.88 (range: 0.86-0.93). Predation by wolves (Canis lupus) and other predators was implicated as the most common cause of death for ...

BESNOITIOSIS IN A WOODLAND CARIBOU

Journal of Wildlife Diseases, 1976
Besnoitiosis was diagnosed in an adult male woodland caribou found dead in northern Saskatchewan. The lesions present were comparable to those of chronic besnoitiosis in cattle, and were much more severe than those previously described in domestic reindeer and barren-ground caribou.
