Global patterns of biodiversity are influenced by spatial and environmental variations in the rate at which new species form. We relate variations in speciation rates to six key patterns of ...

Spatial isolation is known to promote speciation - but researchers at Ludwig-Maximilians-Universitaet (LMU) in Munich have now shown that, at least in yeast, the opposite is also true. New ecological ...

A paper published by URI researchers reveals key mechanisms in speciation in corals. Critically threatened by climate change, a better understanding of coral biology will help efforts to conserve and ...

Two reproductive isolated morphs of Arctic charr (Salvelinus alpinus), termed profundal and littoral charr according to their different spawning habitats, co-occur in the postglacial lake ...

Four new, sexually reproducing hybrid species have originated in the British Isles during the past 100-400 years. Two of these are allopolyploids (Senecio cambrensis and Spartina anglica), one is a ...

Biologists drove the divergence of different-sized feather lice from a single population. In four years, the evolved lice had trouble mating with each other -- a sign of speciation. A few years ago, ...

It's a bit like a character in a movie going off and having adventures that change him so drastically that when he returns, the folks in his hometown no longer recognize the way he looks and behaves.

Clues from fish diversity suggest that interbreeding between species could be a major mechanism of fast speciation. To biologists eager to understand how one species can split into two, the apple ...
