Individual variation in behavior and physiology is a widespread and ecologically functional
phenomenon in nature in virtually all vertebrate species. Due to domestication of laboratory …

Two population oscillations dominate terrestrial community dynamics in northern Canada. In
the boreal forest, the snowshoe hare (Lepus americanus) fluctuates in cycles with an 8–10 …

Predation, one of the most dramatic interactions in animals' lives, has long fascinated
ecologists. This volume presents carnivores, raptors and their prey in the complicated net of …

The hypothesis that the regular multiannual population oscillations of boreal and arctic small
rodents (voles and lemmings) are driven by predation is as old as the scientific study of …

Field naturalists have observed the activities of weasels for centuries. Their descriptions
were often accurate but sometimes misinterpreted the animals' behaviors and underlying …

The periodicity of mass occur-rence of some northern small rodents has been known from at
least the mid-sixteenth century, when Archbishop of Uppsala, Swew den;.'Olaus Magnus …

Cycles characterize the demography of many populations of microtine rodents and
snowshoe hares. A phase of low numbers often follows the decline and introduces a lag that …

A geographical gradient in the relative impact of generalist and specialist predators on small
rodent populations has been hypothesized to be responsible for the gradient in cyclicity …

Comprehensive analyses of long–term (1977–2003) small–mammal abundance data from
western Finland showed that populations of Microtus voles (field voles M. agrestis and …

The high‐arctic tundra ecosystem has the world's simplest vertebrate predator–prey
community, with only four predators preying upon one rodent species, the collared lemming …
