New study targets long antelope migration in western Wyoming


Biologists have begun the most detailed study yet of an antelope herd that makes the longest big-game migration in the lower 48 states.

Scientists recently put tracking collars on 30 antelope in the herd, a larger sample using more sophisticated devices than in any previous study. The scientists plan to spend three years studying what affects the animals' health, survival and migration.

The scientists want to find out whether wolves, fences and gas drilling might be affecting the roughly 400 antelope, also known as pronghorn.
