Variation in sexual size dimorphism (SSD) is a widespread phenomenon and is commonly
attributed to variation in sex-specific patterns of selection. According to Rensch's rule, SSD …

Brain sizes vary substantially across vertebrate taxa, yet, the evolution of brain size appears
tightly linked to the evolution of life histories. For example, larger brained species generally …

Identifying variations in morphology and age across geographical gradients may help us to
understand the evolution of life-history of animals. In view of this, we studied variation in …

Identifying the patterns of body size and age in relation to altitudes may help us to
understand the evolution of life history of organisms. With this view, we compared the …

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 …

The central area of Argentina has been greatly affected mainly due to urbanization and
intensive agriculture (corn, soybean and cattle). Age, longevity and growth were determined …

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 …

Age structure, growth and longevity was determined in the common toad, Rhinella
arenarum, from a suburban pond located in the Pampa plains, central Argentina during two …

We studied demographic traits of a subtropical frog, Rana nigromaculata, in two populations
from different altitudes (300 and 800 m) in southwestern China over two successive years …

Age determination in amphibians is crucial to the investigation of life-history traits. In this
context, we studied, for the first time, the life-history traits of Boana pulchella from a sample …
