These reindeer were almost hunted to extinction in the early 1900s, but dedicated recovery programs helped them repopulate. Here we investigate the extent to which selection has led to similar life-history strategies in the 3 most numerous trichostrongyle species. Svalbard reindeer can reach speeds of up to 80 km (50 mph) at a sprint. The Svalbard reindeer is adapted to survive the variable climatic conditions and the high degree of seasonality in Svalbard. The vegetation is lush by the foot of bird cliffs and other breeding places for birds. Seven national parks and twenty-three nature reserves cover two-thirds of the archipelago, protecting the largely untouched, yet fragile, natural environment. On the other hand, female reindeer grow antlers beginning in June and keep them for an entire year. The animals sometimes travel in huge herds over long distances and are good swimmers. Male reindeer develop antlers from April through July, shedding the velvet covering in late summer. Compared to other reindeer, they are short-legged and have a small, rounded head.

Management of the Svalbard reindeer, which is only found in Svalbard, is an all-Norwegian responsibility. The main adaptations between the two were height and weight, the svalbard reindeers are without a natural predator so live in small groups without … Svalbard reindeer are isolated on the high-arctic archipelago of Svalbard under austere nutritional conditions, while the semi-domesticated Norwegian reindeer migrate between lush coastal summer pastures and inland taiga and boreal forest habitats with ground lichens in winter on mainland Norway. They are very sedentary and thus have low energy demands, and they have an outstanding ability to use their own body reserves (both fat and muscle tissue) when access to food is limited in the winter. physiological adaptations of Svalbard reindeer to the High Arctic environment and counter-intuitive impacts of climate change on its population dynamics. The pads on the bottom of the hooves change their features in summer and in winter in order to provide the best traction. Male reindeer develop antlers from April through July, shedding the velvet covering in late summer. The expected lifespan of a Svalbard reindeer is about ten years, but the oldest animal recorded is 17 years of age. 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. This is energetically very advantageous, because even a moderate trotting speed of 7 km h −1 increases energy expenditure four times on solid ground in treadmill experiments ( Nilssen et al., 1984b ). In summer they feed on lush vegetation where ever it is available, particularly in valleys and lowland plains and they spend most of their time feeding to accumulate fat. The Svalbard reindeer has a varied diet and eats almost all types of vegetation with a few exceptions (such as arctic white-heather). Reindeer also spent more time resting during the winter and less time foraging for food than in the summer. At the end of a long Arctic winter, spring is starting to awaken. Rangifer tarandus platyrhynchus. ) The Svalbard reindeer is a sub-species of reindeer that only lives in Svalbard. They are relatively sedentary, and are thus highly vulnerable to changes in local conditions. Males lose their antlers in early winter. In the Nordic countries the semi-wild reindeer are known to feed mainly on Caldonia spp. 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.

At the end of a long Arctic winter, spring is starting to awaken. Males are larger than females. “This is a group that’s had a whole lot of opportunity to adapt to some of the harshest climate that we’ve had,” Welker said. 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 fur is brown on the back and light on the belly and varies between the seasons. The males develop large antlers during the period from April to July and shed the velvet during August-September. The harvest was banned, except for scientific sampling, between 1925 and 1983. These smaller groups may also gather during the winter due to limited feeding grounds. In winter the reindeer feed along ridges, mountain slopes, plateaus and other areas where little snow accumulation occurs. For example, the proportion of mature females that give birth to a calf in a given summer can vary from 10 to 90%. The working group for the Conservation of Arctic Flora and Fauna (CAFF) also prioritizes reindeer monitoring.
