It appears that it’s not just the bees, frogs, and other reptiles that are at risk of dying off.

Moose in the northern US are dying in what could be the start of a huge climate shock to the world’s boreal forests.
The die-off is most dire in Minnesota, where ecologists say moose could be gone within a decade. But it extends across the southern edge of the animal’s global range – populations are falling as far away as Sweden.
“It’s broader than I thought when I started looking into it,” says Ron Moen of the University of Minnesota Duluth, who will present a survey of North American moose populations at the Moose Health conference in Uppsala, Sweden, this week.
No single cause seems to be responsible across all regions. In Minnesota, many moose seem to be dying of parasitic worms called liver flukes; in Wyoming, some researchers are pointing to a worm that blocks the moose’s carotid arteries; in New Hampshire, massive tick infections seem to be the culprit.
