Gray Wolf - Wikipedia, the free encyclopedia |
 | | The Gray Wolf, being a keystone predator, is an integral component of the ecosystems to which it typically belongs. |
 | | Wolf growls have a distinct, deep, bass-like quality, and are used much of the time as a threat, though they are not always necessarily used for defense. |
 | | In brief, the gray wolf, which, at one point, could be found in any ecosystem on every continent in the Northern Hemisphere, was persistently one of the first species to go once a significant population of humans settled in a given area. |
