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 …

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 …

Darevskia rudis (BEDRIAGA, 1886) occupies a wide range of altitudes in the Black Sea
region of Turkey. A total of 62 individuals of this lizard from three populations/locations at …

We used skeletochronology to determine the ages of 249 (93 females, 108 males and 48
juveniles) odorous frogs (Odorrana grahami) from four locations covering an altitudinal span …

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 …

Brain size varies dramatically between vertebrate species. Two prominent adaptive
hypotheses–the Cognitive Buffer Hypothesis (CBH) and the Expensive Brain Hypothesis …

Most anurans exhibit sexual size dimorphism (SSD). This morphological variation between
the sexes may be attributed to different ages at maturity, growth rate, or longevity. We …

Horticulture poses a significant ecological risk, as agrochemicals are applied more
frequently and in larger quantities per unit of production compared to extensive crop fields …
