The Role of Translocation in Recovery of Woodland Caribou Populations

Conservation Biology, 2010
Abstract:  Maintenance of viable populations of many endangered species will require conservation action in perpetuity. Efforts to conserve these species are more likely to be successful if their reliance on conservation actions is assessed at the population level. Woodland caribou ( Rangifer

Fire, lichens, and woodland caribou (Rangifer tarandus caribou) in Canada's Boreal Shield

, 2020
Threatened woodland caribou (Rangifer tarandus caribou) have experienced large range recessions and population declines across much of Canada’s boreal forest in the last century and have become a major focus of conservation efforts in the region.

Anthropogenic Disturbance and Population Viability of Woodland Caribou in Ontario

Journal of Wildlife Management, 2020
One of the most challenging tasks in wildlife conservation and management is to clarify how spatial variation in land cover due to anthropogenic disturbance influences wildlife demography and long‐term viability.

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 ...

Invasive Adenocarcinoma of the Head of a Boreal Woodland Caribou (Rangifer tarandus caribou), Alberta, Canada

Journal of Wildlife Diseases, 2022
An emaciated, 14-yr-old female boreal woodland caribou (Rangifer tarandus caribou) was found dead with an ulcerated wound on the left side of the head. Radiographs documented osteolysis of portions of the mandible and cranium. Histopathology revealed an invasive adenocarcinoma infiltrating the soft tissues and bones of the head.

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.

Simulation of conservation and management of woodland caribou

Ecological Modelling, 2004
Abstract The decline in woodland caribou (Rangifer tarandus caribou) populations in Alberta lead to classification as a threatened species. Rapid industrial development continues to affect caribou habitat. Natural and anthropogenic factors, which affect population dynamics, act cumulatively. We developed an interactive cumulative effects model, which

Validation of a Demographic Model for Woodland Caribou

Journal of Wildlife Management, 2010
Abstract: Wildlife population models are potentially valuable for conservation planning. Validation is necessary to ensure that models are sufficiently robust for predicting management outcomes consistent with conservation objectives. Sorensen et al. (2008) produced a model of woodland caribou (
