Thank you Henrik. That was helpful. Since your paper was linked to a large news depository site, you probably received larger exposure than you might normally for such a specialized field. Perhaps the term is quite common among your specialty area, but since mine is outside of that, it is helpful to understand some of the graphs that simply display a number (in meters).

However, although I am biologist my curiosity was tied more into my hunting interests. Now that I understand the term a bit better, I can contemplate the implications of your methodology and the ramifications of elk hunter/prey relationships.

In any case, it is a fascinating study and the results are quite remarkable, particularly with respect to hunting season and harvesting methods.
