Background Sexual size dimorphism (SSD) is related to ecology, behaviour and life history
of organisms. Rensch's rule states that SSD increases with overall body size in species …

Rensch's rule claims that sexual size dimorphism (SSD) increases with body size when
males are larger but decreases with body size when males are smaller. Chinese wood frog …

Environmental variation can promote differentiation in life-history traits in species of anurans.
Increased environmental stress usually results in larger age at sexual maturity, older mean …

Aim Longevity is a critical life‐history trait of organisms. Multiple abiotic and biotic factors are
thought to exert different selection pressures, resulting in a great variation in species …

If this compensation is correct, the mass of the left testis should be positively correlated with
degree of testes asymmetry, and the degree of directional testes asymmetry of the males in …
