Most small rodent populations in the world have fascinating population dynamics. In the
northern hemisphere, voles and lemmings tend to show population cycles with regular …

Both biotic interactions and abiotic random forcing are crucial influences on population
dynamics. This frequently leads to roughly equal importance of deterministic and stochastic …

Why do organisms become extremely abundant one year and then seem to disappear a few
years later? Why do population outbreaks in particular species happen more or less …

Individual-based models are an exciting and widely used new tool for ecology. These
computational models allow scientists to explore the mechanisms through which population …

Trophic cascades—the top-down regulation of ecosystems by predators—are an essential
aspect of ecosystem function and well-being. Trophic cascades are often drastically …

Suggestions of collapse in small herbivore cycles since the 1980s have raised concerns
about the loss of essential ecosystem functions. Whether such phenomena are general and …

Can physics be an appropriate framework for the understanding of ecological science? Most
ecologists would probably agree that there is little relation between the complexity of natural …

Hurlbert divides experimental ecologist into 'those who do not see any need for dispersion
(of replicated treatments and controls), and those who do recognize its importance and take …

Mountain areas often hold special species communities, and they are high on the list of
conservation concern. Global warming and changes in human land use, such as grazing …

While population cycles are geographically widespread, it is on arctic tundra that such
cycles appear to be most influential for the functioning of the whole ecosystem. We give an …
