In 1978 after about 100 years of absence, 15 Svalbard reindeer, Rangifer tarandus platyrhynchus were reintroduced to Brøggerhalvøya, a peninsula on the north-western coast of Svalbard. This stock had increased to about 200 animals in 1989.

High seasonal overlap in habitat suitability in a non-migratory High Arctic ungulate
Understanding drivers of space use and habitat selection is essential for management and conservation, especially under rapid environmental change. Here, we develop summer and winter habitat suitability models for the endemic wild Svalbard reindeer ...

Sustainable tourism: a valid remedy against climate change impact in every context. The Svalbard and Kiribati archipelagos [PDF]
: Climate change, with relevant global warming, has a deep and global impact on environment but the consequences on local populations and respective economic activity may differ in a significant way depending on the dissimilar socio-economic conditions.

Spatiotemporal distribution of Arctic herbivores in spring: Potential for competition?
Biotic interactions are important to the structure and dynamics of food webs and may affect the spatial and temporal distribution of species. In the Arctic, spring snow-cover limits food availability at a critical time for herbivores, potentially leading

Impact of Tusk Anomalies on the Long-Term Foraging Ecology of Narwhals. [PDF]
We combined stable δ13C and δ15N isotope analysis and genetic sexing to investigate whether narwhals with dental anomalies have a distinct long‐term foraging ecology. Our results showed no difference in stable isotope signature of two‐tusked male and one‐tusked female narwhals relative to normal‐tusked narwhals, indicating that an extra tusk does not ...

Why don't Svalbard reindeer migrate?
Reindeer and caribou are best known as migratory, seasonally nomadic animals; many continental populations, for example, travel between distinct summer and winter ranges which may lie hundreds of km apart. Much less is known about the movements of animals belonging to island populations.

When the sun never sets: diverse activity rhythms under continuous daylight in free-living arctic-breeding birds [PDF]
Circadian clocks are centrally involved in the regulation of daily behavioural and physiological processes. These clocks are synchronized to the 24-hour day by external cues (Zeitgeber), the most important of which is the light-dark cycle.

Estimating the daily dry matter intake of Svalbard reindeer in late winter
Svalbard reindeer (Rangifer tarandus platyrhynchus) store large reserves of subcutaneous fat during summer and autumn which, it has been suggested, might be sufficient to meet a substantial part of their energy requirements during winter.
