Arctic wolf spider6/22/2023 Stable isotope analyses and a laboratory experiment confirmed mosquito consumption by P. However, females near ponds produced about 20% more eggs per egg sac. glacialis abundances, sizes, and the proportion of females with an egg sac were similar throughout the season both near and far from ponds. Nearly 90% of the wolf spiders collected in our study were Pardosa glacialis, the species that subsequently became the focus of our analyses. We used pitfall trapping to compare the abundance, size, and fecundity of wolf spiders collected near (< 1 m) versus far (75–100 m) from the margins of three tundra ponds before, during, and after mosquito emergence. In this study, we investigated emerging mosquitoes (Diptera: Culicidae) as a resource subsidy for wolf spiders (Araneae: Lycosidae) in western Greenland, an area where significant pond drying has occurred in recent decades. However, this aquatic-terrestrial linkage may be disrupted by rapid warming that is causing a decrease in freshwater habitats across large areas of the Arctic. The average population of wolves in the sanctuary is 8 – 10 over 40 acres, of which some are rescued wolves who were injured, unwanted or abandoned.Aquatic insects are often consumed by terrestrial predators in Arctic tundra. The White Wolf Sanctuary is a refuge for Arctic wolves located in Tidewater, Oregon. The Arctic Wolf is classed as ‘Least Concern’. Though extremely unusual, it is possible for an adult wolf to retain its blue-colored irises.Īrctic Wolves have achieved life spans of over 18 years in captivity however, in the wild, the average life span is only 7 – 10 years. The wolf pups stay with their mother for 2 years.Īt birth, wolf pups tend to have darker fur and their eyes have blue irises that will change to a yellow-gold or orange color when the pups are between 8 and 16 weeks old. Female Arctic wolves have a gestation period of about 63 days. It is generally thought that the lower number of pups compared to the average of 4 to 5 among Grey Wolves is due to the lack of prey in the Arctic. The mother gives birth to 2 or 3 pups in late May to early June, about a month later than Grey Wolves. Due to the Arctics permafrost soil and the difficulty it poses for digging dens, Arctic Wolves often use rock outcroppings, caves or even shallow depressions as dens instead. Normally, only the alpha male and female Arctic wolves breed, however, in large packs others may mate as well. Moose are also common prey, their long legs may render them slow and at times, stuck, in thick snow, leaving them vulnerable to attacks by wolf packs.Īs grazing plants are scarce, they roam large areas to find prey up to and beyond 2600 kilometres squared (1000 square miles) and they will follow migrating caribou during the winter. They mostly prey on Caribou and musk oxen, however, they will also kill a number of Arctic Hares, seals, ptarmigan and lemmings, as well as other smaller animals. Arctic wolves can be black, grey or white.Īrctic wolves, like all wolves, hunt in packs. The alpha male is always the largest and will continue growing after other wolves had stopped. Weights of up to 175 pounds (80 kilograms) have been observed in full-grown males.Īrctic Wolves usually have small ears, which help the wolf maintain body heat. Their shoulder heights vary from 25 to 31 inches (63 to 79 centimetres).Īrctic Wolves are bulkier than Grey Wolves, often weighing over 100 pounds (45 kilograms). Male Arctic Wolves are larger than female Arctic Wolves. The Arctic Wolf and the Timber Wolf are the only subspecies of the Grey Wolf that still can be found over the whole of its original range, largely because in their natural habitat they rarely encounter humans.Īrctic Wolves generally are smaller than Grey Wolves, measuring around 3 to 6 feet (0.9 to 1.8 metres) long including the tail. The Arctic Wolf (Canis lupus arctos), also called Polar Wolf or White Wolf, is a mammal of the Canidae family and a subspecies of the Grey Wolf.Īrctic Wolves inhabit the Canadian Arctic and the northern parts of Greenland.
