Status and trends of Rangifer tarandus and Ovibos moschatus populations in Canada
We identified 97 Rangifer tarandus and 17 Ovibos moschatus populations in Canada. In July 1991, the Canadian populations totalled 1.9 to 2.6 million caribou, 13 600 reindeer and 108 600 muskoxen.

Beginning with a single step: A social theory of change for managing chronic wasting disease
Following opinions of chronic wasting disease management experts, we identified and prioritized critical interventions to address the disease. We developed a theory of change for the most prioritized intervention that supports the implementation of engagement or social marketing strategies to increase support for management.

Transferrin variation and evolution of Alaskan reindeer and caribou, Rangifer tarandus L.
Polyacrylamide gel electrophoresis was used to analyse transferrin variation in wild caribou (Rangifer tarandus granti) and domestic reindeer (R.t. tarandus) from Alaska. Eighteen alleles were detected in caribou and ten alleles were detected in reindeer.

Caribou forage lichens were present in post‐burn lodgepole pine stands multiple decades before stem‐density was likely open enough to attract wintering caribou. We posit that the prolonged self‐thinning of lodgepole pine after fire may be a greater limiting factor than lichen abundance for habitat recovery in lodgepole pine forests.

Two caribou mortality events in Northwest Alaska: possible causes and management implications
During fall and winter 1994—1995 and winter 1999—2000, caribou (Rangifer tarandus granti) from the Western Arctic Herd experienced high, localized mortality in northwest Alaska near Cape Thompson.

ABSTRACT This study examines faunal assemblages from paired semisubterranean houses and middens at 10 Early Inuit sites spanning the North American Arctic (ca. 1200–1500 ce) to evaluate whether local resource bases or other factors primarily structure zooarchaeological variability.

Reindeer grazing induces spatial and functional shifts in root systems of boreal pine forests
The spatial distribution of roots, laterally and vertically, is critical for nutrient and water uptake and for driving root‐associated carbon inputs and turnover. Large herbivores, such as reindeer, influence ecosystems belowground by altering aboveground vegetation composition and soil microclimate.
