Table 1 Site summary information for the six sites used in
isotope analysis broken up by early and late-dying trees. Range and
number of years used in isotope analysis per site/timing combination as
well as the number of trees and their range in death dates. Comparisons
of tree size (i.e., diameter at breast height, DBH), carbon isotope
discrimination (∆13C), and correlation between
inter-annual variation in ∆13C and climatic moisture
deficit (CMD) among sites, for trees that died early versus late in the
outbreak. Standard deviation is included in parenthesis for DBH and
∆13C. CMD was averaged for June, July and August for
inter-annual correlations of ∆13C versus CMD
correlations.
