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