An understanding of population dynamics requires explanations for both the patterns of
fluctuations and the densities at which they occur. To identify the causal mechanisms …

I. The regular multiannual oscillations of small mammals at northern latitudes have been a
subject of intensive study from the beginning of this century. The existence of a subjective …

Periodic fluctuations or cycles in populations of small mammals have been widely studied,
but much controversy still exists about their causes. Cycles of voles and lemmings are …

We studied responses of stoats and least weasels to fluctuating vole abundances during
seven winters in western Finland. Density indices of mustelids were derived from snow …

The cause of population cycles in microtines (voles and lemmings) remains an enigma. I
propose a new solution to this problem based on a crucial feature of microtine biology, shifts …

In 1929, a group of scientists, working at Oxford University, began" the pursuit of the
ecological Holy Grail," an endeavor devoted to the search for the secret mechanisms behind …

Patterns of population dynamics are determined by the interaction between density—
dependent and density—independent processes. To examine the responsiveness of various …

Current ecological information on periodically fluctuating microtine populations are
demonstrated to support a hypothesis involving both predation and intrinsic self-regulation …

Based on evidence from a series of recent studies linking behaviour to demography in
experimental vole populations we propose how intrinsic and extrinsic factors interact …

Home range size can vary within a species due to differences in the quality of habitat,
distribution and abundance of food, or population density (Hixon 1980, Ostfeld 1985, Wolff …
