Using experimentation to understand the 10‐year snowshoe hare cycle in the boreal forest of North America
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 …

Moving forward in circles: challenges and opportunities in modelling population cycles
Population cycling is a widespread phenomenon, observed across a multitude of taxa in
both laboratory and natural conditions. Historically, the theory associated with population …

Bistability and limit cycles in generalist predator–prey dynamics
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 …

Phase tip**: how cyclic ecosystems respond to contemporary climate
We identify the phase of a cycle as a new critical factor for tip** points (critical transitions)
in cyclic systems subject to time-varying external conditions. As an example, we consider …

Seal body condition and atmospheric circulation patterns influence polar bear body condition, recruitment, and feeding ecology in the Chukchi Sea
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 …

Linking climate change to population cycles of hares and lynx
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 …

Seasonally varying predation behavior and climate shifts are predicted to affect predator-prey cycles
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 …

The hidden history of the snowshoe hare, Lepus americanus: extensive mitochondrial DNA introgression inferred from multilocus genetic variation
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 …

Stochastic resonance in climate reddening increases the risk of cyclic ecosystem extinction via phase‐tip**
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 potential and flux landscape theory of ecology
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 …
