We studied field voles in grassy clear-felled sites in Kielder Forest, northern England. Weighing less than 50 grams (1.8 ounces), this stout vole is 15 to 20 cm (5.9 to 7.9 inches) long, including its short tail (3 to 6 cm). Population ecologists have a long and continuing fascination with factors that shape stable, outbreak, and cyclic population dynamics. In some parts of the world, field-vole populations can fluctuate widely over 3 to 4-year cycles, with numbers rising and falling dramatically. Abstract. To investigate the role of seasonality in the generation of population cycles, we decompose the annual (fall-to-fall) density dependence, as well as the density-

Grazing . time series from 84 populations of the gray-sided vole [Clethri-onomys rufocanus (Sundevall, 1846)] from Hokkaido, Japan (Fig. 1995). Field voles are primarily found in open areas with plenty of long grass. Vole population cycles: Kin-selection or familiarity? Meadow vole, (Microtus pennsylvanicus), one of the most common and prolific small mammals in North America. Where do field voles live? Populations fluctuate cyclically between approximately 20 and 700 voles ha −1 in optimal habitats with a 3–5-year period (see Lambin et al. These have been particularly well studied for voles (Clethrionomys and Microtus) in Europe, Fennoscandia, and Japan.In Europe, stable populations of the bank vole (C. glareolus) have relatively constant densities across years in forests with few mast …

'The role of colonization in patchy population dynamics of a cyclic vole species' (manuscript). population cycles ignore the geographically widespread cycles of common voles: indeed, we could only find two mentions of common vole cycles (one of which without any reference to a paper) in the eight most recent reviews of cyclic dynamics of small rodents (Table 1). in grasses may drive field vole population cycles. Typically, the puzzle of rodent population cycles is reframed as that of the ‘ (2000) for details).

Population cycles driven by weasel–vole interactions are said to be dampened by the stabilizing impact of generalist predators in southern Fennoscandia.
In some parts of the world, field-vole populations can fluctuate widely over 3 to 4-year cycles, with numbers rising and falling dramatically. Kin selection, as evidenced by aggression between individuals with a low coefficient of relation, may be a significant contributing factor in vole population cycles.
