Article
Full-text available
Late Pleistocene climate changes have deeply impacted the range dynamics of temperate species. While the genetic legacy of these dynamics has been widely investigated, little is known about their phenotypic consequences. Anti-predatory strategies offer intriguing opportunities to study phenotypic evolution in response to dispersal dynamics since th...
Article
Full-text available
Background Hotspots of intraspecific genetic diversity represent invaluable resources for species to cope with environmental changes, and their identification is increasingly recognized as a major goal of conservation ecology research. However, even for iconic and endangered species, conservation strategies are often planned without thorough inform...
Article
Full-text available
Understanding the genomic underpinnings of antipredatory behaviors is a hot topic in eco-evolutionary research. Yellow-bellied toad of the genus Bombina are textbook examples of the deimatic display, a time-structured behavior aimed at startling predators. Here, we generated the first de novo brain transcriptome of the Apennine yellow-bellied toad...
Article
Full-text available
Amphibian biodiversity loss in recent years has exceeded that of all other groups of vertebrates. In this context, biodiversity hotspots represent priority targets for conservation in amphibian populations. However, little information is available on the distribution and conservation status of amphibian species within most biodiversity hotspots. He...
Article
Full-text available
Assigning individuals to their source populations is crucial for conservation research, especially for endangered species threatened by illegal trade and translocations. Genetic assignment can be achieved with different types of molecular markers, but technical advantages and cost saving are recently promoting the shift from short tandem repeats (S...
Article
Full-text available
Recent empirical and theoretical studies suggest that personality and locomotory performance traits linked to dispersal abilities are crucial components of the dispersal syndromes, and that they can evolve during range expansions and colonization processes. Island colonization is one of the best characterised processes in dispersal biogeography, an...

Patterns of mito-nuclear discordance across secondary contact zones have been reported in a wide range of animal and plant organisms. They consist of a spatial mismatch between nuclear and mitochondrial genomes, in terms of the geographic location and/or extension of the secondary contact zone between distinct evolutionary lineages. Several theoret...

Dispersal is a key process in ecology and evolution as it contributes to shaping the spatial patterns of biological diversity at all its levels of organization. Growing evidence is unveiling the role of phenotypic trait variation in affecting dispersal dynamics of populations, and that substantial, rapid, and directional changes in the phenotypic m...

Inter-individual variation in antipredatory strategies has long attracted curiosity among scientists. Deimatisms is a complex and time-structured antipredatory strategy consisting in prey suddenly unleashing unexpected defences to frighten predators and stop their attack. Being deimatism traditionally considered as a stereotyped antipredatory respo...

The field of molecular phylogenetics is being revolutionized with next‐generation sequencing technologies making it possible to sequence large numbers of genomes for non‐model organisms ushering us into the era of phylogenomics. The current challenge is no longer how to get enough data, but rather how to analyse the data and how to assess the suppo...

Article
Full-text available
Objective Athletic performances are dynamic movements that are physically challenging and often predict individual success in ecological contexts. They stem from a complex integration of multiple phenotypic traits— e.g ., morphological, physiological and behavioural—that dictate animal survival and individual fitness. However, directly quantifying...

Article
The Tyrrhenian tree frog, Hyla sarda, is an amphibian endemic to the Tyrrhenian islands (Western Mediterranean). Previous investigations of its Pleistocene evolutionary history suggested that it colonised the northern portion of its current range, through a spatial diffusion process from the Sardinia island, during the last glaciation. However, sou...
Article
Full-text available
Genetic diversity feeds the evolutionary process and allows populations to adapt to environmental changes. However, we still lack a thorough understanding of why hotspots of genetic diversity are so 'hot'. Here, we analysed the relative contribution of bioclimatic stability and genetic admixture between divergent lineages in shaping spatial pattern...
Article
Full-text available
Accurate species delimitation is of primary importance in biodiversity assessments and in reconstructing patterns and processes in the diversification of life. However, the discovery of cryptic species in virtually all taxonomic groups unveiled significant gaps in our knowledge of biodiversity. Mimicry complexes are good candidates to source for cr...

Article
Full-text available
Unprecedented rates of biodiversity loss raise the urgency for preserving species ability to cope with ongoing global changes. An approach in this direction is to target intra-specific hotspots of genetic diversity as conservation priorities. However, these hotspots are often identified by sampling at a spatial resolution too coarse to be useful in...
Article
It is now well established that Southern European peninsulas have been major glacial refugia for temperate species during Pleistocene climatic oscillations. However, substantial environmental changes occurred also within these peninsulas throughout the Pleistocene, raising questions about the role and interplay of various microevolutionary processe...
Article
Full-text available
Alien marsh frogs were found during bioacoustic surveys in the Aspromonte National Park, southern Italy, during spring 2015. This is to date the southernmost finding of non-native water frogs in the Italian Peninsula. Subsequent genetic characterization clearly identified these non-native frogs as belonging to Pelophylax kurtmuelleri, a species of...

The Forest Dormouse (Dryomys nitedula) is a small rodent with a wide, albeit severely fragmented distribution, ranging from central Europe to central Asia. Within the Italian region, D. nitedula populations are restricted to forested mountain areas of two largely disconnected regions, the eastern Alps and the Calabria region, where two distinct sub...

Mediterranean peninsulas are major biodiversity hotspots, and cold-adapted species are an important component of this biodiversity. However, cold-adapted species contributed surprisingly little to our knowledge of the intimate links between Quaternary environmental changes, species’ responses to these changes, and current patterns of intraspecific...

Full-text available
Rare hybridisations between deeply divergent animal species have been reported for decades in a wide range of taxa, but have often remained unexplained, mainly considered chance events and reported as anecdotal. Here, we combine field observations with long-term data concerning natural hybridisations, climate, land-use, and field-validated species...

The amphibian chytrid pathogen Batrachochytrium dendrobatidis (Bd) is considered a major cause of amphibian population declines, particularly in montane areas. Here, we investigated the presence and distribution of Bd among populations of 3 mid- to high-altitude species spanning the entire Italian peninsula (486 individuals from 39 sites overall):...

Faunistics and ecological profile of the macromoths of Parco Regionale di Veio (Latium, Central Italy) (Macrolepidoptera). Data on the macromoth communities of Parco Regionale di Veio (Latium, Central Italy) are given. 226 species of 11 families were inventored as a whole from ten study sites corresponding to three major environmental types: ripar...
