Relationship between mean tree δ15N values (1975-1980) and trunk dbh (cm) at breast height at Bag Harbour, Haida Gwaii. Circles represent individuals trees with salmon carcasses present (closed circle) and absent (open circle). Numbers above symbols represent tree age, as determined by coring. Standardized regression coefficients shown for salmon carcass trees and control trees. Statistical probabilities (P < 0.01 & NS) shown for two regression slopes.
