As climate warms, mice morph

Lakes Environmental Research Inc., Receives Landmark Patent

New research by McGill University biologists shows that milder winters have led to physical alterations in two species of mice in southern Quebec in the past 50 years – providing a textbook example of the consequences of climate change for small mammals.

The findings also reveal a stark reversal in the proportions of the two mice populations present in the area, adding to evidence that warming temperatures are driving wildlife north.  

At McGill’s Gault Nature Reserve, about 40 kilometres east of Montreal in the St. Lawrence valley, biologist Virginie Millien for the past 10 years has been studying two similar, coexisting species: the deer mouse and the white-footed mouse. Both are common in eastern North America. But while the deer mouse can be found in Canada’s northern reaches, the white-footed mouse is a more southerly species, rarely found north of the St Lawrence River.
