We explored age-related parameters and growth patterns in a population of Dermatonotus muelleri inhabiting the Arid Chaco, at the southern limit of the species' distribution range using skeletochronology. In addition, we ...

In amphibians from tropical or subtropical regions well-expressed growth marks in bone could be expected because of the existence of strong dry/wet seasons, but little evidence is available. Additionally, temporal patterns ...

In this study we analysed the body size, age structure, age at maturity, longevity and growth pattern of Argenteohyla siemersi pederseni in north-eastern Argentina using skeletochronological methods. Body size was sexually ...

For ectotherms, like lizards, the temperature plays a key role in shaping life history traits such as age and size at sexual maturity, longevity and growth rates. In cold temperate habitats, like Patagonia, lizards must ...

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 breeding seasons, in 2000 and 2008 by using ...

Individuals devote energy intake to growth, maintenance and reproduction, so knowing the way in which they allocate this energy between competing demands is essential to understand their relationship with the environment. ...

In the toad Bufo calamita, among-population variation of size follows roughly a converse Bergmann cline, but populations exist that do not fit this pattern. We propose that latitudinal body size variation is a byproduct ...

We present the first data on age structure, growth pattern, and lines of arrested growth (LAG) for Leptodactylus latrans in temperate wetlands. Based on these data, we estimate LAG periodicity, age, size at sexual maturity ...

We used skeletochronology to assess the age structure, body size and sexual maturity in two populations of Liolaemus pictus argentinus from San Carlos de Bariloche, Argentina. The species occupies a wide Altitudinal range ...

Recent studies predict that several lineages of tropical animals are at particular risk given current estimates of global climate change. Yet, much uncertainty exists on the effects of climate shifts in ectothermic species ...
