Article
Full-text available
The Wall Gecko shows heterogeneous colour pattern, which may vary among individuals, depending on the time of day and on the habitat segregation. Nocturnal pale geckos live exclusively on walls. Diurnal dark geckos preferentially live on olive tree trunks, demonstrating an ability to change skin colour that is superior to that of the pale gecko and...

Identification of the species is a crucial step in many ecological studies. Sometimes, this could become a challenge, because of animal elusive behavior, low density population or for sympatric species leaving similar signs that are impossible to discriminate based only on their morphology. Here, we set up non-invasive molecular method to discern b...

The Italian hare (Lepus corsicanus) is endemic to Central-Southern Italy and Sicily, classified as vulnerable due to habitat alterations, low density and fragmented populations and ecological competition with the sympatric European hare (Lepus europaeus). Despite this status, only few and local studies have explored its ecological features. We prov...

Full-text available
We characterized the genetic structure of the Eurasian otter (Lutra lutra) meta-population living in the core of its Italian distribution range providing results from 191 fresh spraints, collected from 24 watercourses included in Southern Italy. Furthermore, according to ecological corridors and barriers, we discuss the likely ways of movement and...
Article
Full-text available
Animals living on small islands are more drastically exposed to environmental changes, such as food or water starvation, and rapid temperature shifts. Facing such conditions, and probably thank to adaptive plasticity mechanisms, some animals display a Reversed Island Syndrome (RIS), a suite of traits, including skin pigmentation, voracity, sexual d...
Article
Full-text available
Domestication is an intriguing evolutionary process. Many domestic populations are subjected to strong human‐mediated selection, and when some individuals return to the wild, they are again subjected to selective forces associated with new environments. Generally, these feral populations evolve into something different from their wild predecessors...
Article
Full-text available
This study has two main objectives: to define the presence of an alien species, the coypu (Myocastor coypus), in the Campania region and to develop a demographic projection in the absence of management plans. It was possible to highlight the areas in which the species is currently present on the territory and, once the biological and ecological asp...
Article
Full-text available
Mediterranean mountain landscapes are undergoing a widespread phenomenon of abandonment. This brings, as a consequence, the loss of traditional land use practices, such as transhumant pastoralism, as well as shrub and wood encroachment, with repercussions on the biodiversity associated with semi-open, human-managed landscapes. In this study, we foc...
Article
The Apennine wolf (Canis lupus italicus, Altobello, 1921) is currently experiencing a period of great population change. Any information that helps to understand this transformation will be valuable for managing it. Here we provide, for the first time, quantitative data (habitat suitability, segregation, seasonal activity, daily time budget, social...
Article
Full-text available
Background: The Eurasian otter (Lutra lutra) underwent a strong decline in large areas of the Central-Western part of its distribution range, during the second half of the twentieth century. In Italy, only residual fragmented nuclei survive in the Central-Southern part of the peninsula. Nowadays, the otter is one of the most endangered mammals in...
Article
Full-text available
The Italian hare (Lepus corsicanus) is an endemic species of the Central-Southern Italy and Sicily, classified as vulnerable by the International Union for Conservation of Nature because of the impact of human habitat alterations, the low density and fragmentation of sub-populations and the ecological competition with the European hare (Lepus europ...
Article
Full-text available
The ecological theory of island biogeography suggests that mainland populations should be more genetically divergent from those on large and distant islands rather than from those on small and close islets. Some island populations do not evolve in a linear way, but the process of divergence occurs more rapidly because they undergo a series of pheno...

Article
Full-text available
Some insular lizards show a high degree of differentiation from their conspecific mainland populations, like Licosa island lizards, which are described as affected by Reversed Island Syndrome (RIS). In previous works, we demonstrated that some traits of RIS, as melani-zation, depend on a differential expression of gene encoding melanocortin recepto...

Full-text available
Artificial selection affects phenotypes differently by natural selection. Domestic traits, which pass into the wild, are usually negatively selected. Yet, exceptionally, this axiom may fail to apply if genes, from the domestic animals, increase fertility in the wild. We studied a rare case of a wild boar population under the framework of Wright's i...
Poster
Global climate change will alter plant communities in mountain grazing. As a consequence, browsing animals could suffer change in food availability especially when they are highly specialized. Here, we analyzed this issue for two sympatric Lepus species living in Southern Italy, the endemic Italian hare (Lepus corsicanus) and global widespread Euro...

Project
Populations of organisms confined to islands often evolve extensive morphological and behavioral changes often over a short time. We hypothesize that adaptations to island life depend on a regulatory solution rather than genomic mutation, summarizing in a different use of the genome by the insular populations.
Project
in this project we place all the works that can serve as useful tools for management and conservation biology.
Project
Several time-based and ecological factors promote speciation, although divergent selection often initiates the process of speciation, it often fails to complete it.
