Posted March 31, 2016

Scientists have shown for the first time that common bird populations are responding to climate change in a similar pronounced way in both Europe and the USA.

Virus evolution differs by species of mosquito carrier

Posted

A new study on how the West Nile virus evolves in four species of mosquitos shows that viruses accumulate mutations in their insect carriers that reduce how well they reproduce when passed on to a bird host. Viruses carried by one of the tropical species were best able to maintain their reproductive fitness and thus spread. The study could help in the prediction of future viral outbreaks.
