Natural selection in house mice (Mus musculus) from South Georgia (South Atlantic Ocean)
Mice living in tussock grass on a remote headland of the South Atlantic island of South Georgia (54°S) where the mean temperature is less than 2°C and the monthly average below 0°C for four months each year have been studied. They are big animals (although not as large as those on some North Atlanti...
