Use of Sulfur and Nitrogen Stable Isotopes to Determine the Importance of Whitebark Pine Nuts to Yellowstone Grizzly Bears
Entry ID:
NRMSC_sulfurnitrogenstableisotopes
Summary
Abstract:
Whitebark pine (Pinus albicaulis) is a masting species that produces relatively
large, fat- and protein-rich nuts that are consumed by grizzly bears (Ursus arctos horribilis). Trees produce abundant nut crops in some years and poor crops in other years. Grizzly bear survivial in the Greater Yellowstone Ecosystem is strongly linked to variation in pine-nut availability. Because whitebark pine ... ![]()
