Circadian organization in reindeer
Nature, 2005The light/dark cycle of day and night synchronizes an internal 'biological clock' that governs daily rhythms in behaviour, but this form of regulation is denied to polar animals for most of the year. Here we demonstrate that the continuous lighting conditions of summer and of winter at high latitudes cause a loss in daily rhythmic activity in reindeer ...

Recent developments in physical activity assessment of reindeer offer a possibility to identify reindeer activity in the archaeological record. These include species-specific muscle attachment site scoring, identification of activity-related pathologies, and bone biomechanical properties.

Pulmonary circulation in the reindeer
Basic Research in Cardiology, 1978Right heart catheterizations were performed in 56 sessions on 25 reindeer with determinations of blood pressure and oxygen saturation. Cardiac output was calculated from cineangiocardiograms. When the animals were placed in prone position, heart rate was about 50/min, mixed venous blood oxygen saturation 68 to 72%, right ventricular systolic pressure ...

I have been receiving an increasing number of referred cases of illthrift and death in reindeer recently imported into England from Scandinavia. I don't have much knowledge of this species, but it would seem that having evolved as migratory deer they have little innate ability to cope with ...

Reproduction in female reindeer
Animal Reproduction Science, 2000Reindeer are either wild or kept under very extensive farming systems. They are seasonal breeders, with mating coinciding with the decreasing photoperiod in the autumn, and with calving in the spring. Little is known regarding the factors that influence reproduction in reindeer or of their reproductive physiology.

Epidemiology of reindeer parasites
Parasitology Today, 1986Every Christmas we sing about Rudolph the red-nosed Reindeer, but do we give much thought to why his nose is red? The general consensus is that Rudolf has caught a cold, but as far as I know no proper diagnosis has been made of his abnormal condition.
