The relationship between the fat content of Svalbard reindeer in autumn and their death from starvation in winter

open access: yesRangifer, 1986
The relationship between body fat reserves in autumn and age-specific mortality in winter were examined in Svalbard reindeer (Rangifer tarandus platyrhynchus Vrolik).

Mortality in Svalbard reindeer

open access: yesEcography, 1983
Mortality rates in Svalbard reindeer followed the “U”‐shaped pattern, with higher mortality rate among calves and old animals than in middle aged individuals. Assuming a stable population size, the mortality data predict a 16.2% annual mortality and recruitment rate among 6 months and older animals, and a male:female sex ratio of 48.5:51.5 among 1‐yr ...

Transferrin variation and evolution of Alaskan reindeer and caribou, Rangifer tarandus L.

open access: yesRangifer, 1986
Polyacrylamide gel electrophoresis was used to analyse transferrin variation in wild caribou (Rangifer tarandus granti) and domestic reindeer (R.t. tarandus) from Alaska. Eighteen alleles were detected in caribou and ten alleles were detected in reindeer.

Lichen bleaching as a response to long‐term experimental warming in the High Arctic

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Lichens are an important component of Arctic ecosystems. Studies have indicated a decline in the abundance of Arctic lichens during recent decades, which is often attributed to competitive pressure from vascular plants.
