Reindeer must build up body mass during the short (6-8 weeks) and cool ( < 10 °C) summer (Halvorsen and Bye 1999 ); doing this depends on plant biomass production and the availability of preferred forage species such as graminoids, both of which are influenced by July temperatures (van der Wal and Stien 2014 ). The arctic archipelago of Svalbard is already experiencing dramatic effects from climate change. The Svalbard reindeer has a varied diet and eats almost all types of vegetation with a few exceptions (such as arctic white-heather). Percentages of species/species groups 6 SD across individuals in the late winter diet in 2000 (n = 8), 2001 (n = 8), and 2002 (n = 8) based on rumen samples from female Svalbard reindeer (Rangifer . Male reindeer grow to 28 to 53 inches (70 to 135 centimeters) tall from hooves to shoulder, and around 5.9 to 6.8 f (1.8 to 2.1 m) long. We investigated dietary variation during three winters in female Svalbard reindeer (Rangifer tarandus platyrhynchus) on the basis of rumen samples from animals culled in early and late winter during 2000-2002. RUMEN SAMPLES For the winter diet, rumen content was sampled in October and April/May from 50 female Svalbard reindeer that were culled Naturalists look through the skat onshore to get a better idea as to what the animal eats, analyzing items such as hairs. A polar bear chases a reindeer into the water, drags it ashore and devours it, in a striking scene caught on film for the first time. During the winter, Svalbard reindeer forage in areas where snow has less chance to accumulate. Arctic Cod 5. The little arctic shrub that is an important component of the diet of Svalbard reindeer. During the summer and when access to food is easier, these reindeer spend most of their time feeding in order to accumulate enough fat to survive the next winter. During the growing season the availability of plants with high biomass and/or quality is high. whilst grass species are still significant components of the svalbard originally characterised on starch, sus-like puls encoded in reindeer diet accounting for 14-26% of daily feed intake [17]. Lily Z. Zhao, Albert S. Colman, R. Justin Irvine, Stein Rune Karlsen, Gerard Olack, Erik A.

On Svalbard, reindeer remains account for 27.3% in polar bear scats, suggesting they "may be a significant part of the polar bear's diet in that area". the study area supports one of the largest populations of Svalbard reindeer, with a population size that fluctuated between 300 and 665 animals during the period 1979-1999 (Solberg et al., 2001). While high-fat, high-calorie ringed and bearded seals make up their main diet, polar bears are also known to feed on eggs, birds, rodents and even dolphins. One study found that lichen makes up just 2 per cent of the diets of Svalbard reindeer, she said. All of these are readily available and high in energy and protein.

The diet of polar bears. Unlike the caribou in Alaska, Svalbard reindeer don't have to live in fear of predators such as wolves or bears. The presence of lichen secondary compounds in faeces from Svalbard reindeer shows that lichens are indeed included in their diet, although probably in small amounts because of depleted pastures. Svalbarði Polar Iceberg Water 6. Weighing between 70 and 90 kilos (155. As the northernmost reindeer population on the planet, they are thick and round, which makes it easier for them to tolerate the cold. Table of Contents * The Evolution of Food Culture in Svalbard 1. During both winter and summer, Svalbard reindeer selectively feed on different types of vegetation that are not only a source of nutritional value, but also a place of heavy metal accumulation. Their observations are the first detailed account of a complete and successful polar bear hunt of a Svalbard reindeer. While high-fat, high-calorie ringed and bearded seals make up their main diet, polar bears are also known to feed on eggs, birds, rodents and even dolphins. Agriculture in Svalbard - the archipelago containing the world's northernmost permanently inhabited settlements - has a short history, and remains a minor economic factor, but has nonetheless had a culturally and socially significant role, as well as an ecologic impact.Svalbard is home to the Global Seed Vault, which serves to protect the world's biological and agricultural diversity. The Svalbard reindeer (R. t. platyrhynchus) from Svalbard Island is very small compared to other subspecies (a phenomenon known as insular dwarfism) and is the smallest of all the subspecies, with females having a length of approximately 150 cm (59 in), and a weight around 53 kg (117 lb) in the spring and 70 kg (150 lb) in the autumn.

In this article we focus on the winter diet of female Svalbard reindeer by analyzing rumen samples from culled animals. In summer, the sea ice retreats and takes with it the seals that make up the polar bear's main . barbatus) and birds seemed to be minor components in the diet, while Svalbard reindeer (Rangifer tarandus platyrhynchus), considering its size and the frequency with which it occurred in the scats (9.2 %), likely plays a more important role in the diet than previously reported. Description: The Arctic tern is the only tern that breeds in Spitsbergen, and it is thus unmistakable.

In order to survive on changing diet the reindeer has to be able to conserve energy and protein in the winter and accumulate body reserves during the summer. Because of specific climate conditions of the archipelago, the diet of Svalbard reindeer is divided into a summer diet, dominated by the green parts and flowers of vascular plants and graminoids, and a winter diet, consisting of cryptogams and woody parts of dwarf-shrubs, which are the only source of food available to reindeer after removing .
