Population cycles have long fascinated ecologists from the time of Charles Elton in the
1920s. The discovery of large population fluctuations in undisturbed ecosystems challenged …

Population cycling is a widespread phenomenon, observed across a multitude of taxa in
both laboratory and natural conditions. Historically, the theory associated with population …

We identify the phase of a cycle as a new critical factor for tipping points (critical transitions)
in cyclic systems subject to time-varying external conditions. As an example, we consider …

Since generalist predators feed on a variety of prey species they tend to persist in an
ecosystem even if one particular prey species is absent. Predation by generalist predators is …

Polar bears (Ursus maritimus) are experiencing loss of sea ice habitats used to access their
marine mammal prey. Simultaneously, ocean warming is changing ecosystems that support …

The classic 10‐year population cycle of snowshoe hares (Lepus americanus, Erxleben
1777) and Canada lynx (Lynx canadensis, Kerr 1792) in the boreal forests of N orth America …

Human activity is leading to changes in the mean and variability of climatic parameters in
most locations around the world. The changing mean has received considerable attention …

The functional response of some predator species changes from a pattern characteristic for
a generalist to that for a specialist according to seasonally varying prey availability. Current …

Hybridization drives the evolutionary trajectory of many species or local populations, and
assessing the geographic extent and genetic impact of interspecific gene flow may provide …

The species in ecosystems are mutually interacting and self sustainable stable for a certain
period. Stability and dynamics are crucial for understanding the structure and the function of …
