Wolves, moose and biodiversity: An unexpected connection http://apocadocs.com/s.pl?1257164940
Moose eat plants; wolves kill moose. What difference does this classic predator-prey interaction make to biodiversity?
A large and unexpected one, say wildlife biologists from Michigan Technological University. Joseph Bump, Rolf Peterson and John Vucetich report in the November 2009 issue of the journal Ecology that the carcasses of moose killed by wolves at Isle Royale National Park enrich the soil in "hot spots" of forest fertility around the kills, causing rapid microbial and fungal growth that provide increased nutrients for plants in the area.
"This study demonstrates an unforeseen link between the hunting behavior of a top predator -- the wolf -- and biochemical hot spots on the landscape," said Bump.... And he adds that on the Arctic tundra, where soil nutrients are limited, others have found that the impact of a muskox carcass on surrounding vegetation is dramatic even after 10 years.
