PREDATORS -- Wolf research in the news includes a report on a study revealing indications that wolves suffer stress when heavily hunted.

OK....

I wonder if moose and elk are stressed when wolves are in the neighborhood?  Some research indicates yes.

My English setter is stressed when I leave home in the morning if I don't invite him along to go pheasant hunting -- however, I'm sure some pheasants and quail are stressed when I let my dog loose on Palouse farm ground.

Seriously, I don't discount any research that might have evolutionary implications in wildlife.

On the other hand, maybe we could conclude that a little stress in our increasingly crowded world is unavoidable, and move on from there.
