The introduction of reindeer to Brøggerhalvøya, Svalbard: grazing preference and effect on vegetation

open access: yesRangifer, 1993
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

open access: yesGlobal Ecology and Conservation, 2023
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]

open access: yes, 2020
: 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.

Seasonal variations and responses to normal activity of the deep body temperature in the Svalbard reindeer (Rangifer tarandus platyrhynchus)

open access: yesRangifer, 1986
Deep body temperature was recorded in two female Svalbard reindeer during summer and winter. The reindeer were subjected to naturally occurring weather, photoperiod and stimuli in outdoor pens on Svalbard.

Spatiotemporal distribution of Arctic herbivores in spring: Potential for competition?

open access: yesGlobal Ecology and Conservation, 2023
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]

open access: yesEcol Evol
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?

open access: yesEcography, 1989
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]

open access: yes, 2013
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

open access: yesRangifer, 1987
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.
