Table 1.
Summary of G-tests on data from 23 collection sites throughout New Caledonia. (The ‘edge’ columns give G-values for the goodness-of-fit tests and, in brackets, the edge bias in the site data at the 0.05 probability level: R, right edge; L, left edge; none, no edge bias. The ‘direction’ columns give results of the independence tests for any effect of leaf spiral direction: T, trailing edge bias; none, no spiral direction effect. Summary totals appear at the bottom of the table: A, anticlockwise-spiralling; C, clockwise-spiralling. ID numbers can be used to locate respective sites in figure 1. *p<0.05; *p<0.01; ***p<0.0001.)
