Wolves in areas where the animals are heavily hunted have higher stress and reproductive hormones compared with those under lower hunting pressure, suggests a new study involving scientists from British Columbia, Alberta and Israel.

They compared steroid hormone levels in hair of wolves living in Canada’s tundra-taiga region, which has heavy rates of hunting, with those in the northern boreal forest, where hunting rates are lower.
