Eligible studies had to assess the effects of herbivores on tundra ecosystems (e.g., grazing, browsing, trampling, and other effects, such as fertilizing, digging, or grubbing) or experimental simulations of these effects. Herbivores are considered here as multicellular, terrestrial organisms, and s...
Are Arctic Foxes Carnivores, Herbivores, or Omnivores? Arctic foxes are omnivores, meaning they eat both meat and plants. Are Arctic Foxes Dangerous to Humans? Arctic foxes are small and fast — but not a massive threat to humans. However, always be cautious around wild animals and keep your...
Selecting the right location for a nest or den during the breeding season is one type of habitat selection that is likely to affect reproductive success (Doligez and Boulinier 2008). The breeding period is a critical time for many animals, because of the need to shelter their vulnerable and...
Permafrost does for instance limit the opportunities for Arctic animal to dig out dens and burrows, and it favours plants that do not require a deep root system. On the tundra you can encounter fairly large grazing Arctic animals like caribou and muskox, as well as smaller herbivores like ...
Diet and feeding: A wide variety of food sources, the majority is of large herbivores such as moose, caribou, deer, elk, etc. Also smaller prey animals are eaten along with livestock, carrion, and garbage, arctic wolves are opportunistic as are many predators. Conservation status: Least ...
As the frozen ground warms much faster than expected, it’s reshaping the landscape—and releasing carbon gases that fuel global warming.
For free-ranging animals living in seasonal environments, hypometabolism (lowered metabolic rate) and hypothermia (lowered body temperature) can be effective physiological strategies to conserve energy when forage resources are low. To what extent such strategies are adopted by large mammals living under...

the appetite response at lowTa, provision of warm water did not affect intake. Thus, whereas adult reindeer restrict intake by mobilization of endogenous reserves the calf thermogenic response was an increase in appetite that indicated the importance of access to a food base for calves in winter....
ruminants evolved into a variety of species that could use a relatively narrow range of ecological conditions more efficiently than other less-specialized animals. Among the ruminants, the bovids were singularly adept at tailoring their size, shape, feedingapparatus, digestive system, dispersion pattern...
