La tordeuse fait la vie dure au caribou forestier sentinelle nord

The budworm makes life difficult for woodland caribou

A team from Université Laval, the University of Saskatchewan and the University of Montana has shown that the spruce budworm is harming the recovery efforts of woodland caribou in Quebec by increasing their risk of being preyed upon by wolves in ecosystems that have been ravaged by the insect.
