Global warming might shrink ant workers by as much as a third, says Michael Kaspari at the University of Oklahoma, US, and the Smithsonian Tropical Research Institute in Panama, who carried out the study: 'And since ant species with small workers appear to be particularly successful at invading, ant invasions - already destructive - may become more common in a warming world.'Gil's probably right that this will be ridiculed by those who question the science of climate change. I have to wonder, though, if this couldn't be a really big problem for less developed countries.
