Waterlogging of soil induces diverging rates of senescence in Svalbard reindeer forage plants

Arctic, Antarctic, and Alpine Research
As climate change is unfolding faster in the Arctic than in any other biome, thermal and hydrological changes are predicted to reshape Arctic ecosystems. Water availability is expected to affect the end of the plant growth season, a time period essential

Comparison of the genetic variation in Svalbard and Norwegian reindeer

Canadian Journal of Zoology, 1985
Polyacrylamide gel electrophoresis was used to score for genetic variation in 35 loci in Svalbard reindeer, Rangifer tarandus platyrhynchus, and in reindeer, Rangifer tarandus tarandus, from two localities in northern Norway. In R. t. platyrhynchus the proportion of polymorphic loci was 0.114 and the average heterozygosite was 0.030. In R. t. tarandus

Immigration and Regional Distribution of Abomasal Nematodes of Svalbard Reindeer

Journal of Biogeography, 1987
Sixty-three adult (>1 year) Svalbard reindeer (Rangifer tarandus platyrhynchus) from the Arctic island Spitsbergen were all parasitized by abomasal nematodes of the family Trichostrongylidae. Seven species of nematodes were recorded. Of these, Grosspiculaqia occidentalis was found only in reindeer from inner parts of Nordenskiold Land, and specimens of

Svalbard reindeer and its interaction with extreme polar environment

2022
Two distinct populations of Svalbard reindeer are compared based on their antler parameters. Relative antler size and number of tines are supposed to reflect well environmental conditions of the sedentary population within the growing season. Both studied populations are well spatially isolated due to high mountain ridges, glaciers and fjords.

Heart rate and energy expenditure in resting and running Svalbard and Norwegian reindeer

American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1984
The purpose of this study was to determine whether a convenient relationship could be found between heart rate (HR) and energy expenditure at rest and during running in the high arctic Svalbard reindeer (SR) and the subarctic Norwegian reindeer (NR). Measurements of HR and energy expenditure (O2 consumption) were made at different ambient temperatures,

Seasonal changes in the adherent microflora of the rumen in high-arctic Svalbard reindeer

Canadian Journal of Microbiology, 1993
Seasonal changes in bacterial colonization of the epithelial tissue were examined in the rumen of high-arctic Svalbard reindeer. Samples of tissue were collected from eight sites in the rumen of reindeer during summer and winter and bacterial colonization was examined using scanning and transmission electron microscopy.
