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 …

The age and growth of individuals in a population of the water frog Rana epeirotica, from
northwestern Greece, were studied in 1998 and 1999 using skeletochronology. Analysis of …

Determining the age of individual animals is extremcy important for demographic, population
dynamics, or life history studies of amphibians (Castanet and Smirina 1990; Hemelaar and …

To determine how climate factors influence age, body size and sexual size dimorphism
(SSD) in the Mediterranean region, we generated data on age and body size of the …

We investigated lines of arrested growth (LAG) of long bone tissues in a total of 157
salamanders of Hynobius kimurae from Tokyo and Kyoto, Japan. The number of LAGs did …

In 2003 and 2004, we surveyed different populations of Taipei grass frog (Rana taipehensis)
living at Sanchih and Yangmei, Taiwan, using waist-band and toe-clipping methods. Sex …

Body size and age structure were studied for two breeding populations of the salamander,
Hynobius tokyoensis, in the southern Kanto plain of Honshu, Japan. The mean snout-vent …

A long-standing challenge for amphibian population ecologists is the reliable estimation of
age in individuals without known recapture history. The development and widespread …

Background The tendency for organisms to be larger in cooler climates, the so-called
Bergmann's rule, has been widely observed in endotherms, but it is debatable in ectothermic …

Many amphibian species in western North America have been studied to the extent that their
general natural history can be broadly defined (Storer 1925; Stebbins 1951, 2003; Grismer …
