This book provides an introduction to population dynamics, exploring rules that govern
change in any dynamic system and applying these general principles to populations of living …

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 …

The collared lemming in the high-Arctic tundra in Greenland is preyed upon by four species
of predators that show marked differences in the numbers of lemmings each consumes and …

Ecologists working on population cycles of arvicoline (microtine) rodents consider three
ecological mechanisms as the most likely explanations of this long‐standing puzzle in …

Hypotheses on trophic dynamics in terrestrial ecosystems fall into two major categories:
those in which plants are assumed to be invulnerable to their consumers and those in which …

The high Arctic has the world's simplest terrestrial vertebrate predator–prey community, with
the collared lemming being the single main prey of four predators, the snowy owl, the Arctic …

The history of the idea that predation rates are functions of the ratio of prey density to
predator density, known as ratio dependence, is reviewed and updated. When the term was …

Ecologists and environmental managers rely on mathematical models, both to understand
ecological systems and to predict future system behavior. In turn, models rely on appropriate …

Coyotes and lynx are the two most important mammalian predators of snowshoe hares
throughout much of the boreal forest. Populations of hares cycle in abundance, with peaks in …
