Validation of a Demographic Model for Woodland Caribou [PDF]

open access: possibleJournal 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.

The Role of Translocation in Recovery of Woodland Caribou Populations [PDF]

open access: possibleConservation Biology, 2010
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.

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.

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

Avoidance of Industrial Development by Woodland Caribou

The Journal of Wildlife Management, 2001
Rapid encroachment on woodland caribou (Rangifer tarandus caribou) habitat by resource extraction industries (oil, gas, forestry, and peat) is occurring throughout northern Alberta, Canada. The effect of this human development on the movement and distribution of threatened woodland caribou remains poorly understood.

A protostrongylid nematode (Strongylida: Protostrongylidae) in woodland caribou (Rangifer tarandus caribou)

Canadian Journal of Zoology, 1976
First-stage protostrongylid larvae found in faeces of woodland caribou (Rangifer tarandus caribou) in northwestern Ontario and Manitoba may be larvae of Elaphostrongylus sp., a well-known agent of neurologic disease in reindeer (Rangifer tarandus tarandus) of Eurasia.

Suckling, weaning, and growth in captive woodland caribou

Canadian Journal of Zoology, 1992
To delimit the different stages of the weaning process and to understand the relationship between suckling and growth, the evolution of suckling performance and mother–young interactions associated with milk transfer was closely monitored in a group of woodland caribou (Rangifer tarandus caribou) from birth up to 160 days.
