Long-tailed voles are most commonly found in rocky situations on mountainsides but are also found in a wide range of habitats from low, wet, spruce woodland to high mountains (Youngman 1975). Annales Zoologici Fennici, 31(3): 343-345. Intrinsic and climatic determinants of population demography: the winter dynamics of tundra voles. (Bondrup-Nielsen and Ims, 1990; Gromov and Polyakov, 1992; Hall, 1981; Lance and Cook, 1998; MacDonald, 2003; Nagorsen, 2002; Ringens, et al., 1977; Wilson and Ruff, 1999), Microtus oeconomus maintains a relatively high basal metabolic rate (compared to most rodents) of 12.5 mL O2 per gram of body mass per hour. having more than one female as a mate at one time, communicates by producing scents from special gland(s) and placing them on a surface whether others can smell or taste them, breeding is confined to a particular season, reproduction that includes combining the genetic contribution of two individuals, a male and a female. Baltimore, Maryland: Johns Hopkins University Press. It can also be found in orchards. Bergman, C., C. Krebs. Accessed November 27, 2020 at https://animaldiversity.org/accounts/Microtus_oeconomus/. Cold acclimation in the tundra vole. Woodland voles have a combined head and body length between 83 and 120 mm; the tail ranges from 15 to 40 mm in length. living in the Nearctic biogeographic province, the northern part of the New World. Help us improve the site by taking our survey. They weigh between 14 and 37 g. There is almost no sexual dimorphism within the species. ADW doesn't cover all species in the world, nor does it include all the latest scientific information about organisms we describe. "Microtus oeconomus" (On-line), Animal Diversity Web. animals that use metabolically generated heat to regulate body temperature independently of ambient temperature. The American Naturalist, 130(4): 475-484. Aars, J., R. Ims. 2002. living in the northern part of the Old World. The mammals of North America. Influence of the root vole, Microtus oeconomus (Pallas), upon the habitat selection of the field vole, Microtus agrestis (L.), in northern Finland. Vole Facts. Journal of Animal Ecology, 64(4): 459-472. Walker's Mammals of the World. Microtus oeconomus (pronounced e-KON-uh-mus), commonly known as the tundra or root vole, is one of only four Holarctic rodents and the only species of Microtus that is found on all northern continents. ), and trematodes (Quinqueserialis nassalli). However, facultative monogamy is adopted in isolated territories or patchy habitats with low densities and can be relatively long-lasting. These burrows are primarily used as traveling corridors along with well-developed runways created above ground and in natural features such as permafrost cracks. Evolutionary Ecology, 4: 261-272. Tundra voles are active throughout the year and do not hibernate or engage in bouts of torpor. The long-tailed vole (Microtus longicaudus) is a common resident of the herbaceous understory of many forests. Contributor Galleries Journal of Animal Ecology, 73(1): 167-178. Hall, R. 1981. In addition, insular subspecies are generally larger than continental counterparts. 2004. Though we edit our accounts for accuracy, we cannot guarantee all information in those accounts. associates with others of its species; forms social groups. Litters produced by northern populations of tundra voles are more female biased than those of southern populations. offspring are produced in more than one group (litters, clutches, etc.) Activity levels also increase with decreases in temperature and are relatively unaffected by humidity and wind due to the protectiveness of preferred habitat types. (Ims, 1997), There is insufficient research on Microtus oeconomus for a definitive lifespan to be established. Postnatal development of thermoregulation in root vole and some comments on the index of homeothermy ability. The dental formula for M. oeconomus follows the basic pattern for all Microtus: incisors 1/1, canines 0/0, premolars 0/0, molars 3/3. 1993.
