Keystone species play an outsized role in the ecosystem, affecting the natural balance in ways that cannot easily be replaced.

How do new species form? Like most areas of Evolutionary Biology, research related to the formation of new species - 'speciation ' - is rich in historical and current debate. Here, we review both ...

When species interact with each other, they do not evolve separately, but do so together. This process is called coevolution. Natural selection favors predators that are better at capturing prey, and ...

No need for niches? Neutral theory explains biodiversity when species are identical. Niche differences, or the unique ways that each species “makes its living” in nature, are the classical explanation ...

Over the years, we’ve turned research, anecdotes and everyday experiences into a whole constellation of stories about the way we impact our world. Still, some voices may be missing from the ...

Imagine looking up at a sky so full of birds, they block out light from the sun. Passenger pigeons (Ectopistes migratorius) used to fly in flocks of hundreds of millions, maybe even billions, of birds ...

When a species comes off the Endangered Species Act list, is that the end of the story? No. While a win is a win, it’s never the end; responsibility for these species often shifts to states, Tribes, ...

The Coleopterists Bulletin, Vol. 33, No. 2 (Jun., 1979), pp. 151-166 (16 pages) The methods pioneered by Steyskal and White for using trend curves of rates of species descriptions to estimate the ...

A species is a distinct group of organisms and the most basic unit used to measure life on Earth. However, there’s no single definition of a species, meaning this vital concept in biology can be ...

Bacterial species, and even specific strains can be differentiated using a number of molecular techniques such as PCR, quantitative PCR, genome sequencing and mass spectrometry. But even without ...
