THE MORPHOLOGY AND PATHOLOGY OF BESNOITIA SP. IN REINDEER (RANGIFER TARANDUS TARANDUS)
Journal of Wildlife Diseases, 1995Four of five reindeer (Rangifer tarandus tarandus) obtained from a Besnoitia sp.- infected herd at the Assiniboine Park Zoo in Winnipeg, Manitoba, Canada, in October 1989, had evidence of mild dermatitis over the articular surfaces of carpal and tarsal joints.

Digital Necrobacillosis in Norwegian Wild Tundra Reindeer (Rangifer tarandus tarandus)
Journal of Comparative Pathology, 2010Outbreaks of digital necrobacillosis in Norwegian wild tundra reindeer (Rangifer tarandus tarandus) are described. The outbreaks occurred in late summer and autumn 2007 and 2008, subsequent to periods with an unusually high number of days with precipitation and high air temperature.

Pestivirus and alphaherpesvirus infections in Swedish reindeer (Rangifer tarandus tarandus L.)
Veterinary Microbiology, 2012Herding semi-domesticated reindeer has economic and social value for Sami people in the northern territories of Fennoscandia. However, with the intensification of reindeer husbandry, interspecies transmission of pathogens between reindeer and domestic animals may become a problem, especially for countries such as Sweden, Norway, and Finland where ...

Transplacental toxoplasmosis in a reindeer (Rangifer tarandus) fetus
Veterinary Parasitology, 2002Toxoplasma gondii infection was diagnosed in a full term stillborn reindeer (Rangifer tarandus) fetus. The fetus had encephalitis and placentitis associated with T. gondii. Tissue cysts were identified histologically in sections of brain and tachyzoites were present in placenta and the myocardium.

Some aspects of thermoregulation in newborn reindeer calves (Rangifer tarandus tarandus)
Acta Physiologica Scandinavica, 1985At birth reindeer calves often are exposed to sub‐zero ambient temperatures (Ta) sometimes even combined with wind and precipitation. The resting metabolism was measured in three different age groups (1, 7 and 14 days old) at Ta's of –20, –5, 10 and 20oC.

Defining the anatomy of the Rangifer tarandus sex chromosomes
Chromosoma, 1998A comprehensive cytogenetic characterization of the unusally large reindeer (Rangifer tarandus) sex chromosomes is presented for the purpose of studying the evolution of these atypical gonosomes. Sex chromosome idiograms were constructed from G-banded and C-banded chromosomes to illustrate the relative amounts and locations of euchromatin and ...

Variation in gestation length among captive reindeer (Rangifer tarandus tarandus)
Theriogenology, 2009An estimated 90% of reindeer females are mated in a 10- to 21-d interval and give birth in an equally synchronized manner. Reported gestation length in reindeer is highly variable (range, 203 to 240 d), almost twice the reindeer estrous cycle length. Previously, we identified a significant, negative relationship between gestation length and conception ...

Ossification of the antler in the Lapland reindeer (Rangifer tarandus tarandus).
Acta anatomica, 1990A histological and histochemical study of biopsy specimens from the Lapland reindeer antler indicated that the intercellular matrix of the cartilage that forms the partitions of longitudinal channels becomes calcified at virtually the initial stage of formation.
