The diet of woodland caribou populations in west-central Alberta

open access: diamondRangifer, 1996
The diet of woodland caribou (Rangifer tarandus caribou) populations in the foothills and Rocky Mountains of west-central Alberta was estimated by microhistological analyses of feces collected in winter and summer. In winter, terrestrial lichens averaged 60-83% of fecal fragment densities in both areas.

Woodland caribou: Facts for forest managers

open access: bronzeThe Forestry Chronicle, 1992
A literature review points to predation as the proximate factor controlling woodland caribou (Rangifer tarandus caribou) populations in most cases, but that finding does not obviate the need for caribou to be included in forest management. Managers must consider the indirect effects of forest operations on caribou through their impacts on caribou ...

The role of predation in the decline and extirpation of woodland caribou [PDF]

open access: greenOecologia, 2005
To select appropriate recovery strategies for endangered populations, we must understand the dynamics of small populations and distinguish between the possible causes that drive such populations to low numbers. It has been suggested that the pattern of population decline may be inversely density-dependent with population growth rates decreasing as ...

Estimation of arboreal lichen biomass available to woodland caribou in Hudson Bay lowland black spruce sites [PDF]

open access: yesRangifer, 2003
An arboreal lichen index to be utilized in assessing woodland caribou habitat throughout northeastern Ontario was developed. The "index" was comprised of 5 classes, which differentiated arboreal lichen biomass on black spruce trees, ranging from maximal ...
