The age structure of amphibian populations plays an essential role in understanding population dynamics, potential impacts of environmental change, and conservation status. The Marsh frog Pelopyhlax ridibundus has become a subject of various studies to investigate age structure and body size variation. However, the populations living at high altitudes were paid less attention to while describing life history traits. Leer más.
Age and size variation in widespread amphibians are often related to latitudinal or altitudinal temperature gradients. Species with toxic skin secretions, such as the fire salamander Salamandra salamandra, are an exception to the rule because their survival rates are relatively unaffected by predation, the major source of amphibian mortality.

In this work, we provide an overview of the age determination methods of amphibians and reptiles, critically evaluating their methodological principles, utility (including range of applicability), as well as experimental and biological limitations. Leer más.
