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 ...

Researchers have demonstrated that the consumption of prey by predators can stimulate a cyclical increase and decrease in chlorovirus populations. The authors of the study in the Proceedings of the ...

Evolution can alter the ecological dynamics of communities, but the effects depend on the magnitudes of standing genetic variation in the evolving species. Using an eco-coevolutionary predator–prey ...

On land or sea, when the zebras, gazelles or even plankton fruitfully multiply, their predators’ abundance doesn’t increase quite as much, a new analysis proposes. This predator-prey relationship— ...

The world is filled with different environments and ecosystems where plants, animals, and even microbes are constantly competing for survival. Sometimes this type of competition is conducted in pretty ...

A new study highlights the potential harm that climate change may have on a number of predator and prey relationships. The new work looks into predator and prey relationships, how they change ...
