Bitsy beetle warms Canada: study http://apocadocs.com/s.pl?1353978198
An army of rice-grain-sized beetles, attracted by warming weather, has moved into Canada's western forests, where its tree massacre is causing the mercury to rise yet further, a study said Sunday.
The voracious horde of mountain pine beetles has invaded about 170,000 square kilometres (65,000 square miles) -- a fifth of the forest area of British Columbia, Canada's western-most province, a research team wrote in the journal Nature Geoscience.
The beetles lay their eggs under the bark of pine trees, at the same time injecting a fungus that protects their offspring but kills the trees with the help of the larvae eating their insides.
As trees are felled, the cooling effect of their transpiration, similar to human sweating, is also lost.
