Sexual dichromatism in animals is usually associated with mating displays and is linked to strong sexual selection. Among amphibians, it has mostly been reported in anurans and only in a few caudates. Here, we investigated sexual dichromatism in the only two extant species of the genus Salamandrina, testing for its possible role in intraspecific co...

Monitoring wild populations is an essential tool to assess the conservation status and the ecological requirements of a species. Capture–mark–recapture (CMR), based on individual recognition, is the most commonly used and most effective technique. However, in cases of species with no individual color pattern, tracing the encounter history of indivi...

In vertebrates, the main tissue devoted to energy storage is the adipose tissue. In salamanders, energy reserves can also be stored in the adipose tissues of the tail. Therefore, we evaluated if energy storage in salamanders' tails is related to individual body condition, life cycle and environmental constraints. We calculated a scaled measure of t...
Article
Ecological networks, usually depicting interactions among species, have been recently down‐scaled to the individual level, permitting description of patterns of inter‐individual resource variation, that are usually hindered at the species level. Optimal diet theory (ODT) models, applied to prey‐predator systems, predict different patterns of nested...

Information on population abundance is important to correctly plan conservation and management of animal populations. In general, capture-mark-recapture (CMR) is considered the most robust technique to estimate population abundance, but it is costly in terms of time and effort. Recently, binomial N-mixture models, based on counts of unmarked indivi...

The canonical model of sex-chromosome evolution predicts that, as recombination is suppressed along sex chromosomes, gametologs will progressively differentiate, eventually becoming heteromorphic. However, there are numerous examples of homomorphic sex chromosomes across the tree of life. This homomorphy has been suggested to result from frequent s...

Amphibians are declining worldwide and one of the major causes of such decline is habitat loss. Forestry practices have a primary role in causing habitat loss and fragmentation, detrimental to amphibians. We studied the ecological requirements of a fully terrestrial and threatened amphibian, the Golden Alpine Salamander Salamandra atra aurorae, whi...

Clay models are frequently used in ecological studies to estimate potential predation rates on small and cryptic vertebrates (Bateman et al. 2016). These models are easy to shape and they retain predator marks, allowing the identification of the body part attacked and of the predator. In herpetological studies, prey models are used to evaluate colo...

The study of trophic ecology of terrestrial salamanders is central for a better understanding of their adaptability and dispersal, in particular in Mediterranean ecosystems where their feeding activity is reduced because of prolonged arid periods. Terrestrial salamanders are generalist predators that feed on a large array of invertebrate prey group...
Article
Recent studies suggest that many organisms actively colonize the subterranean environment to avoid climatic stress, exploit new ecological opportunities and reduce competition and predation. Terrestrial salamanders are known to colonize the more stable subterranean habitats mainly to escape external climatic extremes, while the role of predation av...
