Hearing in Reindeer (Rangifer tarandus)
Journal of Comparative Physiology A: Neuroethology, Sensory, Neural, and Behavioral Physiology, 2001The audiogram of two yearling male reindeer (Rangifer tarandus tarandus) were determined using a conditioned suppression/avoidance procedure. During testing, the animal was drinking from a metal bowl while pure tone signals were played at random intervals and followed by an electric shock in the bowl. By breaking contact with the bowl at sound signals,

Journal of Wildlife Diseases, 1990 Besnoitia sp. was diagnosed in two caribou (Rangifer tarandus caribou) which died of pneumonia at the Assiniboine Park Zoo (Winnipeg, Manitoba, Canada) in 1983. During the following 3 yr besnoitiosis spread to an isolated herd of caribou, to mule deer (Odocoileus hemionus hemionus) and to reindeer (Rangifer tarandus tarandus).

Panting in reindeer (Rangifer tarandus)
American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 2000 Two winter-insulated Norwegian reindeer ( Rangifer tarandus tarandus) were exposed to air temperatures of 10, 20, 30, and 38°C while standing at rest in a climatic chamber. The direction of airflow through nose and mouth, and the total and the nasal minute volumes, respectively, were determined during both closed- and open-mouth panting.

Electrocardiogram of the reindeer, Rangifer tarandus tarandus
Laboratory Animals, 1979Summary Electrocardiograms were recorded for 50 Finnish reindeer of age 1 day to 9 years, using standard and unipolar extremity leads in the frontal plane. The range of heart rate was 40–250 beats per minute. Atrial and ventricular depolarization times were 5–10 ms shorter in newborn calves than in older reindeer, and showed only ...

Dental Anomalies in Caribou, Rangifer tarandus
Journal of Mammalogy, 1971The dentitions of 43 of 1226 caribou (Rangifer tarandus) skulls examined had anomalies. Of the 43, 13 had supernumerary teeth, 25 had missing teeth, and five had extreme variations in root development and abnormal dentary patterns. These anomalies appear to be genetically produced and further study from the standpoint of evolutionary origin might be ...

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.

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 ...

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 ...

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.
