Population oscillations of boreal rodents: regulation by mustelid predators leads to chaos.

TL;DR: The results suggest that the multiannual oscillations of rodent populations in Fennoscandia are due to delayed density dependence imposed by mustelid predators, and are chaotic.
Journal ArticleDOI

Small‐rodent dynamics and predation

TL;DR: The predation hypothesis is reviewed and it is considered it unlikely that the phenotypic and genotypic composition of pop- ulations would be instrumental for generating the broad patterns in rodent oscillations, which may have some population-dynamic consequences.
Journal ArticleDOI

Linking climate change to lemming cycles

TL;DR: It is shown that winter weather and snow conditions, together with density dependence in the net population growth rate, account for the observed population dynamics of the rodent community dominated by lemmings in an alpine Norwegian core habitat between 1970 and 1997, and predict the observed absence of rodent peak years after 1994.
Journal ArticleDOI

The island syndrome in rodent populations.

TL;DR: It is suggested that the intensity or absense of density-depressing factors is primarily responsible for the area effect and serves as a principal factor differentiating island from mainland populations of rodents.
Journal ArticleDOI

Reality as the leading cause of stress: rethinking the impact of chronic stress in nature

TL;DR: It is proposed that chronic stress evolves in a species only if it is adaptive, with the key factors being lifespan and life history.

Gradients in density variations of small rodents: the importance of latitude and snow cover

TL;DR: The gradients observed and differences between continents are interpreted as due to microtine-vegetation interactions in northern European areas poor in generalist predators but with important small mustelid predation, and to similar snowshoe hare-ve getters in mainly Canada-Alaska, where small rodents may serve as alternative prey for numerically fluctuating hare predators, at least in the forests.
Journal ArticleDOI

The importance of a relative shortage of food in animal ecology

TL;DR: The hypothesis proposes that animals live in a variably inadequate environment wherein many are born but few survive, and leads to a concept of populations being “limited from below” rather than “controlled from above”.
Journal ArticleDOI

Microtus Population Biology: Demographic Changes in Fluctuating Populations of M. Ochrogaster and M. Pennsylvanicus in Southern Indiana

TL;DR: The demography of these Microtus species in southern Indiana is similar to that of other cycle voles and lemmings in temperate and arctic areas, since fenced populations seem unable to regulate their density below the limit set by starvation.
Journal ArticleDOI

The Regulation of Plant Communities by the Food Chains Exploiting Them

TL;DR: In 1960, three ecologists at the University of Michigan proposed a "balance of nature" hypothesis, which concluded that the predators, as a group, were limited in abundance by the amount of food they could find and capture.
Journal ArticleDOI

Offensive-Defensive Interactions between Herbivores and Plants: Their Relevance in Herbivore Population Dynamics and Ecological Theory

TL;DR: It is suggested that interactions within and among species of herbivores are better understood in terms of interference and facilitation than in termsof competition.
