Relationship of Temperature and Light Ring Formation at Subarctic Treeline and Implications for Climate Reconstruction
Abstract During the past 8 centuries, light rings (LRs) have occasionally formed in black spruce ( Picea mariana ) at treeline near Bush Lake, northern Quebec (L. Filion, S. Payette, L. Gauthier, and Y. Boutin, 1986, Quaternary Research 26, 272-279; A. Delwaide, L. Filion, and S. Fayette, 1991, Cana...
