Product Details

Lanner details for the first time this fascinating relationship between pine trees and Corvids (nutcrackers and jays), showing how mutualism can drive not only each others' evolution, but affect the ecology of many other members of the surrounding ecosystem as well. Lanner explains that many of the world's pines have seeds not adapted to wind dispersal. Fortunately, their seeds are harvested from the cone and scattered over many miles by seed-eating jays and nutcrackers who bury millions of seeds in the soil as a winter food source. Remarkably, these 'pine nut' dependent birds can find their caches even through deep snow. Seeds left in the soil germinate, perpetuating the pines and guarantee future seeds for future birds. Moreover, the newly 'planted' whitebark pine groves encourage further tree growth, such as Engelmann spruce, and eventually the patches of open-grown woodland coalesce, forming a continuous forest.
