A new study attributes the regular disappearance of white-lipped peccaries in South America to natural population cycles. White-lipped peccaries are a keystone species and ecosystem engineers whose ...

Wildlife populations in the northern reaches of the globe have long been observed to fluctuate or cycle periodically, with dramatic increases followed by catastrophic crashes. Focusing on the early ...

Climate change could trigger "boom and bust" population cycles that make animal species more vulnerable to extinction. Dramatic population fluctuations make species more vulnerable to extinction due ...

Multi-annual population cycles can be generated by life history responses to density dependent changes in adult and pre-reproductive survival. The proximate mechanism linking population dynamics and ...

How can predators coexist with their prey over long periods without the predators completely depleting the resource that keeps them alive? Experiments performed over a period of 10 years have now ...

Populations grow at geometric or exponential rates in the presence of unlimited resources. Geometric populations grow through pulsed reproduction (e.g., the annual reproduction of deer, which have a ...

In our experiments, parthenogenetic planktonic rotifers, Brachionus calyciflorus, consumed unicellular, obligately asexual 12 green algae, Chlorella vulgaris. These were cultured in continuous ...

Bunny booms and bunny busts have deeper roots than bunny lusts. When dark spots obscure the sun, the clock runs out on bunny fun. The snowshoe hare of northern Canada and Alaska offers a lesson in ...
