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 …

Rensch's rule refers to a pattern in sexual size dimorphism (SSD) in which SSD increases
with body size when males are the larger sex and decreases with body size when females …

According to Bergmann's rule, in endothermic species, body sizes of individuals tend to be
larger in colder climates compared to those in warmer climates. Some ectotherms, including …

The development of appropriate management and recovery plans requires a better
understanding of the demography of endangered amphibians. In this study longevity, age at …

Bergmann's rule states that, within species of endotherms, individuals tend to be larger in
cooler environments, and has been reputed to apply to some ectotherms including …

Theory predicts that sexual dimorphism evolves as a consequence of sexual selection. I
studied sexual dimorphism in ten forelimb muscles used in the amplexus of Bufo …

In this study, we validated a scale-reading method estimating age and growth in brown trout
Salmo trutta in wild, landlocked, stream-dwelling populations from mountain headwaters in …
