How important is geographical isolation in speciation?
— 30 Apr 2010 09:40 | BiologyA genetic study of island lizards shows that even those that have been geographically isolated for many millions of years have not evolved into separate species as predicted by conventional…
Successful genome sequencing of pea aphid is a breakthrough for ecology and agricultural research
— 24 Feb 2010 13:05 | EnvironmentA special issue of Insect Molecular Biology reports the detailed analyses of specific aspects of the genome of the important plant pest, the Pea Aphid. The analyses are based on the…
Evolutionary game of rock-paper-scissors may lead to new species
— 22 Feb 2010 17:01 | BiologyNew research on lizards supports an old idea about how species can originate. Morphologically distinct types are often found within species, and biologists have speculated that these…
By feeding the birds, you could change their evolutionary fate
— 4 Dec 2009 08:52 | BiologyFeeding birds in winter is a most innocent human activity, but it can nonetheless have profound effects on the evolutionary future of a species, and those changes can be seen in the…
Inconspicuous leaf beetles reveal environment's role in formation of new species
— 31 Oct 2009 14:05 | BiologyUnnoticed by the nearby residents of St. Johnsbury, Vermont, tiny leaf beetles that flit among the maple and willow trees in the area have just provided some of the clearest evidence…
Museum specimens aid conservation effort in Madagascar
— 17 Apr 2009 13:17 | BiologyThere is a new tool for those developing conservation strategies for threatened species and landscapes: museum specimens. Richard Pearson and Christopher Raxworthy of the American Museum…
Biodiversity itself begets a species cascade, researchers say
— 12 Feb 2009 11:50 | EnvironmentBiodiversity feeds on itself, researchers found, as evolving animals open niches for other new species. Such is the case, says a Michigan State University researcher, with a parasite…
'Great speciators' explained: It's intrinsic
— 27 Jan 2009 17:56 | BiologyNew molecular research shows that birds within the family Zosteropidae - named white eyes for the feathers that frame their eyes - form new species at a faster rate than any other known…
Crimson rosella research could re-write 'ring theory'
— 30 Jul 2008 14:28 | BiologyNew research has uncovered how different crimson rosella populations are related to each other - a discovery which has important implications for research into how climate change may…
