Table 4.  Correlation matrix for major palynological taxa from the Bruneau, Idaho, core.  The original percentage data were transformed by the log-ratio method (Kovach, 1990) prior to analysis.

Key to taxa:
PIN = Pinus
ABI = Abies
CON = other conifers
TCT = Taxaceae-Cupressaceae-Taxodiaceae
QUE = Quercus
TRE = other trees and shrubs
ART = Artemisia
TUB = Tubuliflorae
CHE = Chenopodiineae
SAR = Sarcobatus
POA = Poaceae
HER = herbs and forbs
IND = Indeterminate

Critical values for correlation coefficients for 70 degrees of freedom (df here = 76) are .232 for a = .05 and .302 for a = .01 (Rohlf and Sokal, 1969).  Correlation coefficients in bold are significant at the .01 level and those in italics are significant at the .05 level.
