Eastern meadow voles dig shallow burrows, [9] and in burrows, nests are constructed in enlarged chambers. In winter, nests are often constructed on the ground surface under a covering of snow, usually against some natural formation such as a rock or log. [8] [9] Eastern meadow voles form runways or paths in dense grasses. [8] [9]
However the most marked effect on mating system is population density and these effects can take place both inter and intra-specifically. [21] Male voles are territorial and tend to include territories of several female voles when possible. Under these conditions polygyny exists and males offer little parental care. [23]
Voles are seldom seen outside these runways, which enable a faster and safer locomotion and easier orientation. The climbing ability of the common vole is very poor. Underground nests are dug 30–40 cm (12–16 in) deep into the ground and are used for food storage, offspring raising, and as a place for rest and sleep.
Northern red-backed voles use surface runways through the vegetation as travel corridors. Nests are built in short burrows or under some protective object such as a rock or root. [2] Northern red-backed voles are active all winter and construct long tunnels under the snow. Winter nests typically are placed on the ground among thick moss.
The short-tailed field vole is a small, dark brown rodent with a short tail, distinguishable from the closely related common vole (Microtus arvalis) by its darker, longer and shaggier hair and by its more densely haired ears. The head and body length varies between 8 and 13 centimetres (3.1 and 5.1 in) and the tail between 3 and 4 centimetres ...
Dr. Jenna Podjasek, MD, a board-certified immunologist, allergist and author, explains that the reason why adults older than 65 are at an increased risk for RSV is because the functionality of the ...
New RSV vaccines are now available to help prevent serious infection in people over 60. Doctors explain the RSV vaccine and its side effects in older adults.
The North American water vole or just water vole (Microtus richardsoni) is the largest North American vole. It is found in the northwestern United States and southern parts of western Canada . This animal has been historically considered a member of genus Arvicola , but molecular evidence demonstrates that it is more closely related to North ...
