^*See bottom of Table 4 for taxa used. 

^†SE were calculated according to the binomial law. 

^‡In parentheses, number of pairwise comparisons (data points) available to calculate correlations. 

^§Correlations significant at P < 0.001; other correlations were unsignificant (P > 0.05). 

^¶SE were calculated according to described methods (1). 

NA, not available.
