The bank vole (Clethrionomys glareolus) is a small vole with red-brown fur and some grey patches, with a tail about half as long as its body. A rodent, it lives in woodland areas and is around 100 millimetres (3.9 in) in length. The bank vole is found in much of Europe and in northwestern Asia.
Vernalization (from Latin vernus 'of the spring') is the induction of a plant's flowering process by exposure to the prolonged cold of winter, or by an artificial equivalent. After vernalization, plants have acquired the ability to flower, but they may require additional seasonal cues or weeks of growth before they will actually do so.
Eyes and ears open by eight days. Weaning occurs from 12 to 14 days. Young born in spring and early summer attain adult weight in 12 weeks, but undergo a fall weight loss. Young born in late summer continue growing through the fall and maintain their weight through the winter. Maximum size is reached between two and 10 months. [5] [9]

In winter and early spring, the silver mountain vole feeds mainly on roots of plants and on seeds, these food materials form 87–92% of their stomach composition from November to February. In March, they begin to feed on green plant vegetation, and these fresh greens form 90–99% of their stomach composition from April to September.
Northern red-backed voles live in a variety of northern forest and shrubland habitats. [2] [4] They occur in every major forest type in central Alaska. [5]Plant species commonly found in areas occupied by northern red-backed voles include black spruce (Picea mariana), white spruce (Picea glauca), quaking aspen (Populus tremuloides), paper birch (Betula papyrifera), alder (Alnus spp.), willow ...
Soil biology is the study of microbial and faunal activity and ecology in soil. Soil life, soil biota, soil fauna, or edaphon is a collective term that encompasses all organisms that spend a significant portion of their life cycle within a soil profile, or at the soil-litter interface.
[citation needed] Some bulbs – such as tulips – need cold winters to bloom, while others – such as freesia – can survive a freezing winter. [citation needed] Many domestic plants are assigned a hardiness zone that specifies the climates in which they can survive. Winter gardens are dependent upon the cultivation of winter-hardy plants.
