1997 Response of Northern Red-Backed Voles to a Major Spruce Beetle Infestation study
Reid ME, Reid ME, Reid M. 1997 Response of Northern Red-Backed Voles to a Major Spruce Beetle Infestation study
A significant cause of natural mortality of mature spruce forests in Alaska and other regions of North America is the spruce bark beetle. The impact of beetle-induced habitat changes on small mammals is largely unknown. A mark/recapture effort was conducted on voles for 2 field seasons in the Copper River basin of Alaska where infestations are widespread. Estimates of vole abundance, survival, and recruitment were produced in 3 locations that varied in their degree of beetle-induced spruce mortality. Evidence from vole abundance and recruitment estimates suggest that beetle impact on red-backed voles may be negative, but the lack of a large vole survival response to infestations limits conclusive evidence.
