ScienceDaily (2009-08-14) -- A switch from annual to multiyear colonies and a willingness to feed just about any prey to their young have allowed invasive yellowjacket wasps to disrupt native populations of insects and spiders on two Hawaiian islands, a new study has found."They're consuming anything from geckos to shearwater to tree lice to more juicy items that you would expect them to eat,

Invasion, stress, and spinal arthritis in cane toadsAbstract.-- The impact of invasive species on biodiversity has attracted considerable study, but impacts of the invasion process on the invaders themselves remain less clear. Invading species encounter conditions different from those in their ancestral habitats and are subject to intense selection for rapid dispersal. The end result may be

Underestimation of Species Richness in Neotropical Frogs Revealed by mtDNA AnalysesAbstract.-- Background. Amphibians are rapidly vanishing. At the same time, it is most likely that the number of amphibian species is highly underestimated.
