From: Sexual size dimorphism in anurans fails to obey Rensch’s rule

Figure 2

The relationship between SSD (Log (female mean size) –Log (male mean size) ratio) and SAD (Log (female mean age)–Log (male mean age) difference) for 39 anurans species. Each dot represents a species. A: a significant correlation between SSD and SAD (r = 0.520, P = 0.001); B: a significant correlation between SSD contrasts and SAD contrasts calculated from the phylogenetic tree in Figure3, using the method of independent comparisons (Felsenstein[62]; Garland et al.[66]) (r = 0.339, P = 0.037).
