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.

The social and spatial behaviour of caribou Rangifer tarandus
2021All animals are social at some point in their life. The causes and consequences of animal social behaviour are widely studied, but the integration of space use and spatial features of the landscape within our understanding of social behaviour is not widely studied. My thesis broadly addresses the role of spatial features of the landscape and individual-

A Babesia species isolated from a captive caribou (Rangifer tarandus caribou) with clinical signs of babesiosis and a circulating parasitemia was cultured in vitro. Normal adult caribou erythrocytes supported the growth of the Babesia sp., as did erythrocytes from white-tailed deer (Odocoileus virginianus).

Energy metabolism of barren ground caribou (Rangifer tarandus)
Canadian Journal of Zoology, 1970The heat production of two caribou, during fasting, 91 kcal and 102 kcal/W0.75 per 24 h, was 20 to 30% higher than the quoted interspecific mean of 70 kcal/W0.75 per 24 h. The mean heat production values of two female caribou at the maintenance level of feeding were 107.0 kcal and 124.5 kcal/W0.75 per 24 h.

Caribou kidney is a major source of cadmium (Cd) in the traditional diets of many aboriginal communities in the Arctic. In order to characterize the risk of Cd exposure, we studied the speciation of Cd in caribou kidneys and how, it can be affected by food preparation.

Over the past centuries the native caribou ofWest Greenland has gone through extensive population size fluctuations, with reductionsas great as 90% in less than 20 years.Norwegian semi-domestic reindeer wereintroduced to the Nuuk area in 1952 because ofthe small number of caribou in Greenland.Although the reindeer and caribou wereinitially kept ...

Consequences of travel in the rutting of reindeer and caribou (Rangifer tarandus)
Animal Behaviour, 1970Summary Observations of rutting reindeer indicate that during herding, breeding is greatly intensified and that the general pattern of courtship behaviour exhibited in stationary groups does not occur. This may be explained by concepts which illustrate movement, high density of animals, high excitement and antler contact as possible erotic stimuli ...

Sarcocystis in caribou (Rangifer tarandus terraenorae) in Newfoundland.
The Southeast Asian journal of tropical medicine and public health, 1992Prevalence of species of Sarcocystis in muscle of 36 caribou, Rangifer tarandus terraenorae, shot in Newfoundland, Canada, was 53%. A greater percentage of infected animals were obtained from the central part of the island. The highest concentration of microscopic sarcocysts, 1/mm2 of tissue, was observed in a 5-year old animal.

Serum samples from 1692 reindeer slaughtered in the Mackenzie River Delta in the last decade and from 320 Kaminuriak barren-ground caribou killed between June 1966 and July 1968 were tested for brucellosis. All sera yielding titers of 1:25 or higher were considered to be positive.

Fire, lichens, and woodland caribou (Rangifer tarandus caribou) in Canada's Boreal Shield
2020Threatened 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.
