These include mountain slopes, ridgelines, and plateaus. The Svalbard reindeer is endemic to Svalbard. ... Another important winter adaptations is hibernation. Starvation is the most significant factor keeping the population of this species in check. They have thick coats of fur to protect them from the very cold temperatures. The Svalbard reindeer is a small subspecies of Rangifer tarandus. Svalbard, Name: Svalbard Reindeer (Rangifer tarandus platyrhynchus), Length: 1.5 to 1.6 metres (4.9 - 5.3 feet), Weight: 50 to 90 kg (110 - 198 pounds), males being larger, Appearance: White with darker coloring along their backs and faces. // Get post type (debug) The vegetation is lush by the foot of bird cliffs and other breeding places for birds.

The Svalbard reindeer is short-legged and has a relatively small, rounded head. At the end of a long Arctic winter, spring is starting to awaken. In this study, we investigated if the cold-adapted Svalbard reindeer (Rangifer tarandus platyrhynchus (Vrolik, 1829)) used cool bed sites as a thermoregulatory behaviour in the summer. Yet, many aspects of the species’ biology, impact on the wider ecosystem and susceptibility to various environmental changes remain not well understood. Start your North Spitsbergen cruise with a trek around historic Longyearbyen, then join our expedition to the north of the island to take in the fanta, RVR20-21 The decline was due to a combination of high mortality and migration to other areas.

A Svalbard reindeer, may, owing to the lack of predators, spend 80% of its day lying down or standing and <2% walking and trotting in winter (Tyler, 1987). However, data from many parts of the archipelago and long-term monitoring data from a few specific locations, suggest an increase in the number of Svalbard reindeer during recent decades.

(1979) reported that hind-gut length was relatively larger in Svalbard reindeer than mainland reindeer, and suggested that this was an adaptation to the low-quality, graminoid-dominated forage that characterized their diet in winter. In non-lactating female Svalbard reindeer the mean combined mass of parotid glands was 82.7, s = 4.5, g in September and 58.8, s = 8.7, g in April (P Discover the world's research 17+ million members In winter the reindeer feed along ridges, mountain slopes, plateaus and other areas where little snow accumulation occurs. Reindeer / caribou Adaptations: Low surface area to volume ratio (anatomical) - Being large means it is easier to stay warm by retaining heat generated by the metabolism, adult … Renntier (German) physiological adaptations of Svalbard reindeer to the High Arctic environment and counter-intuitive impacts of climate change on its population dynamics. The Svalbard reindeer has a varied diet and eats almost all types of vegetation with a few exceptions (such as arctic white-heather). Svalbard reindeers are widely distributed in Svalbard in areas with sufficient vegetation. The activity of the grazing animals also naturally affects the plants. Arctic, Destinations: Saved from the brink of extinction by dedicated recovery programs, these small reindeer have a dramatically variable birth rate, Region: For example, the proportion of mature females that give birth to a calf in a given summer can vary from 10 to 90%. The expected lifespan of a Svalbard reindeer is about ten years, but the oldest animal recorded is 17 years of age.

The males develop large antlers during the period from April to July and shed the velvet during August-September. Rangifer tarandus platyrhynchus. ) Svalbard reindeer fur grows lighter in color during winter.

Large populations of Arctic foxes (Alopex lagopus), Svalbard reindeer (Rangifer tarandus platyrhynchus) and marine mammals like polar bears, various species of seals (including walrus) and whales (11) are found. The thickness of the coat contributes to the short-legged appearance and makes even starved animals appear fat in the winter. The body mass of males is approximately 65 kg in spring and 90 kg in autumn, while female body mass is approximately 53 kg in spring and 70 kg in autumn.

The Svalbard reindeer is adapted to survive the variable climatic conditions and the high degree of seasonality in Svalbard. In winter the fur is lighter in colour than in summer, often appearing light grey or yellow-white. Starvation is the most common cause of mortality. Annual monitoring of the reindeer population in Adventdalen (1979–2013) has shown that the population size varies between 400 to 1200 individuals. This harvest is believed to have only minor impacts on the reindeer populations in the area and is managed to be sustainable in the long term. Food items. The reindeer (Rangifer tarandus), also known as the caribou in North America, is a species of deer with circumpolar distribution, native to Arctic, sub-Arctic, tundra, boreal, and mountainous regions of northern Europe, Siberia, and North America.
