The largest species in North America is the water vole, which grows as large as eight or nine inches. (1998). "Chemical cues are necessary but insufficient for reproductive activation of female pine voles (, "Behavioral suppression of female pine voles after replacement of the breeding male", https://en.wikipedia.org/w/index.php?title=Woodland_vole&oldid=984085685, Fauna of the Plains-Midwest (United States), Articles with unsourced statements from October 2014, Creative Commons Attribution-ShareAlike License, Musser, G. G. and M. D. Carleton. Size/Life Cycle. [6] As such farmers see them as pests. Range territory size 700 to 2800 m^2; Home Range. They are chunky rodents with chestnut-brown fur. Its short tail makes up less than 20% of the length. Superfamily Muroidea. The Woodland Vole (Microtus pinetorum) is a small vole with an average body mass of 26 g and a length of about 120 mm. When sensing danger or when surprised, woodland voles make … 894–1531, This page was last edited on 18 October 2020, at 02:24. [6] Staying in a group as a non-breeding individual is beneficial as burrow systems are major investments and a limited resource. The soft, silky fur is glossy brown or chestnut and is darker in the winter than in the summer. Woodland voles are one of the smallest species, usually measuring less than four inches in length. Well adapted for a life of underground burrowing, the pest has small eyes … [4] In order to enter estrus, a female must sense chemosignals in a male and have physical contact. The woodland vole (Microtus pinetorum) is a small vole found in eastern North America. It is also known as the pine vole. The bank vole lives in woodland, hedgerows, parks and gardens. One of the smallest species of voles in North America, woodland voles grow between 4 and 5 inches long and weigh little more than an ounce. Size comparison between a six-foot-tall man, a masked shrew, a jumping mouse, and a woodland vole. [4], Voles prefer to live in soils ranging from loam/peat moss mixtures, to gravel or stone soils, but not very dry soils. pp. It eats fruit, nuts and small insects, but is particularly keen on hazelnuts and blackberries. [9] Females are fiercely loyal to their partners and are highly aggressive towards unfamiliar males. [6] Family groups of the vole are made of a breeding female, a breeding male, their 1–4 offspring and sometimes a few other members that serve as helpers. (2005). [7] A young female vole usually first conceives around 105 days but can conceive as early as 77 days. It has a brown (light or dark) dorsal region with a whitish or silvery underside. The red-backed vole and rock vole are primarily restricted to mountainous areas, and it is the meadow vole and woodland vole that are most often responsible in damage situations. [9], Woodland voles create high economic loss through the damage they cause to apple orchards. [4] Other predators of voles include snakes, weasels and mountain lions. Most anything, given the rare opportunity (Whitaker) Habitat. [4] Alfisol and Ultisol soil types are particularly favored due to being favorable to the vole's burrowing system. This results in a conflict between the surviving parent and its offspring of the same sexes for mating opportunities. They are also susceptible to ectoparasites like lice, fleas, mites, and chiggers. The woodland vole has a head and body length ranging between 3.25–4.75 in (83–121 mm) with a 0.5–1.5 in (13–38 mm) short tail. Its weight ranges between 0.5–1.3 oz (14–37 g). Voles prefer wooded areas with high vertical vegetative stratification but also evergreen shrubs, ground cover, and old fallen logs. [2] They inhabit deciduous forests, dry fields, and apple orchards. [4] Gestation lasts 20–24 days with 1–4 litters produced per year, each with 1–5 young. Woodland Voles are adapted for fossorial (underground) living; they have thick short fur and their eyes, ears and tails are relatively small. However, they can also be found in other habitats from dry fields to the edges of coastal bays. Its short tail makes up less than 20% of the length. [9] A new male in a group gives a non-breeding female a chance to breed although the resident breeding female is still an obstacle. Woodland voles spend their entire lives within the same home range of 700 to 2800 square meters. Its weight ranges between 0.5–1.3 oz (14–37 g). [4] When a vole's partner dies, it is replaced by an unrelated individual. Whitaker, J. O., and Hamilton, W. J. A female will develop a vaginal plug after copulation which lasts for three days. (Kurta, 1995) Communication and Perception. [4][6][7] Helpers are immigrants from other groups. Range and Habitat: The range is most of the eastern U.S., extreme southeastern Ontario, and Southwestern Quebec. This makes them safe from hawks and owls. [3] Deciduous forests with moist, friable soils are suitable for burrowing and voles are most abundant in these habitats. Average measurements: 121 mm (total length), 14-37 g (total weight) (Smithsonian) Predators. The woodland vole has a head and body length ranging between 3.25–4.75 in (83–121 mm) with a 0.5–1.5 in (13–38 mm) short tail. Bank voles are very active and agile animals, and are frequently seen - they even visit bird tables. Group emigration is uncommon and dependent on whether there are available positions in other groups. It measures 11 to 14 cm (4.3 to 5.5 inches) long, including the short tail (1 to 3 cm). [3] Voles cache food, primarily during the winter. They are adept swimmers and are found near streams and alpine meadows in the Northwest. Woodland voles are approximately 118-130 mm (4.6-5.1 in) in total length, and weigh 20-35 g (0.7-1.4 oz). Meadow vole: Water & Prairie Voles. [8] Because females are dispersed with little overlap of different colonies, polygamy is rare among voles. Woodland Vole home range size and dispersal distances are thought to be small in comparison to other species of voles. Urban environments have little impact on vole habitat selection.[3]. Females deliver several litters a year in underground nests built of dead grasses, leaves, and rootlets lined with fine pieces of grass. The woodland vole is one of the smallest members of its genus, weighing 14 to 37 grams (0.5 to 1.3 ounces). Adult voles are larger than shrews or mice. Additionally, voles have short tails, while mice have long tails. Woodland Voles are adapted for fossorial (underground) living; they have thick short fur and their eyes, ears and tails are relatively small. It has a brown (light or dark) dorsal region with a whitish or silvery underside. [4] In addition, apple orchards are a favorite habitat. [6], In the north, the breeding season lasts from March to sometime between November and January. [6] The size and location of the home range and dispersal of groups are limited by neighboring family groups. Females have only four mammae, compared to six in meadow voles, and young attach firmly to their mothers after birth (Hamilton 1938). [5] Voles spend most of their time underground in their burrow systems and seldom venture into the surface. The eyes,external ears and tail are reduced to adapt to their partially subterranean lifestyle. [7] Vole feeding costs apple growers annual losses of nearly $50 million. Highly variable; Deciduous forest in moist, friable soils in which they can burrow easily (Whitaker) Number of pups born in captivity ranged from one to six (Schadler and Butterstein 1979). Gestation lasts from 21-24 days. [4] The burrows are exclusive to the family groups, however a group usually does not need to defend its burrows as other voles usually will not invade them. [citation needed], The woodland vole lives throughout the eastern United States, ranging as far as Nebraska, Kansas, Oklahoma, and Texas. A study on Woodland Voles conducted in New York state reported that calculated mean home range values are 41.7 and 44.7 m2 for females and males respectively (Fitzgerald and … The Woodland Vole (Microtus pinetorum) is a small vole with an average body mass of 26 g and a length of about 120 mm. Breeding information: Woodland Voles breed nearly year round with the peak occurring in early spring. The root systems of trees are an important food source for vole and thus tree spacing affects the density of vole populations. [4], Woodland voles live in family groups in burrow systems in home ranges around 14.75-17.75 in (40–45 cm). In addition, the breeding female in a family group will stress the reproduction of female helpers. In the south, the breeding season continues throughout the year. [4] Because they feed on roots and tubers, voles do not need to drink water much. Litters range in size from 1-8 (usually 2-4) young. Woodland vole litter size is smaller than that of other voles, and averages two to three pups (Paul 1966, Hamilton 1938). [2] Voles feed on both the roots and stem system and the vegetation of plants, as well as fruits, seeds, bark, subterranean fungus and insects. General Biology The meadow vole is most often found in extensive grassy or weedy areas such as old fields and moist hillsides with heavy ground cover.
