Wolves and grizzly
bears<http://animals.nationalgeographic.com/animals/mammals/grizzly-bear/>would
seem to be archenemies, but a new study shows how wolves are actually
helping grizzly bears to obtain tasty, nutritious berries in Yellowstone
National Park <http://www.nps.gov/yell/index.htm>...

The situation began to unfold back in the early 1900s...[with] “predator
control.” By the 1970’s, scientists found no evidence of a wolf population
in Yellowstone, a verdant place that had previously been home to wolves for
ages.  In October 1991, Congress provided funds to the U.S. Fish & Wildlife
Service to start wolf restoration efforts at
Yellowstone<http://www.nps.gov/yell/naturescience/wolfrest.htm>
...

“Wild fruit is typically an important part of grizzly bear diet, especially
in late summer when they are trying to gain weight as rapidly as possible
before winter hibernation,” Ripple said in a press release...with wolves
hunting elk again, there are more berries.
