Description :
This study investigates the nature and strength of the climate signals that characterize an alpine dwarf-shrub, Cassiope mertensiana (mountain bell heather). The AA. present 6 new C. mertensiana chronologies (2 growth, 2 reproduction, 1963-2004; δ13 C, δ18 O, 1975-2005) based on Mount Rainier, Washington, USA. Correlation, factor, and multivariate regression analyses revealed that multiple and different climate factors control the chronologies.
