In the last decades, several European carnivores such as the wolf have experienced a general numerical increase and geographical re-expansion, mainly due to favourable ecological conditions and protective legislation. However, human-wolf coexistence issues and threats to long-term wolf presence are still present. Conservation and management strateg...

Human persecution and habitat decline are global threats for the wildlife, especially for large animals. Despite this trend, in Europe several large carnivore populations are growing, due to species conservation laws and changes in human activity in rural areas. In Italy, the wolf has had a recent transition from threatened to locally abundant, aft...
Article
Full-text available
Large carnivores are making remarkable comebacks in Europe, but how this affects human-wildlife conflict remains unclear. Rebounding carnivore populations lead to increasing livestock depredation, which in turn leads to greater economic losses for farmers. However, returning carnivores could also influence the behavior of wild ungulates, which are...

Full-text available
Intra- and inter-specific gene flow are natural evolutionary processes. However, human-induced hybridization is a global conservation concern across taxa, and the development of discriminant genetic markers to differentiate among gene flow processes is essential. Wolves (Canis lupus) are affected by hybridization, particularly in southern Europe, w...

In the European Union, all bat species are strictly protected and member states must ensure their conservation. However, if populations are genetically structured, conservation units that correspond to whole countries may be too large, putting small populations with specific conservation requirements at risk. Geoffroy's bat (Myotis emarginatus) has...
Article
Full-text available
Human activities can globally modify natural ecosystems determining ecological, demographic and range perturbations for several animal species. These changes can jeopardize native gene pools in different ways, leading either to genetic homogenization, or conversely, to the split into genetically divergent demes. In the past decades, most European w...

Hybridisation between wild and domestic taxa raises complex questions for conservation. Genetic advances offer new methods for hybrid identification, yet social and cultural factors can influence study design, and the interpretation, application, and communication of results. A relevant illustration is hybridisation between domestic dogs (Canis lup...
Article
Full-text available
The canine adenovirus type 2 (CAdV-2) is associated with the infectious tracheobronchitis commonly called "kennel cough", cosmopolitan in dogs but little explored in gray wolves. Our goals were (i) to evaluate the presence and circulation of CAdV-2 in free-ranging Italian wolves (Canis lupus italicus), through the analysis of spleens and tongues co...
Article
Wolves (Canis lupus), like most wild carnivores, are elusive and usually live at low density; this makes it challenging to monitor specific individuals through time. Non-invasive genetic sampling, when protracted over a long period and a sufficiently large geographic scale, has revealed an effective tool to follow individual patterns in a populatio...
Article
Full-text available
Over the last 40 years the gray wolf (Canis lupus) re-colonized its historical range in Italy increasing human-predator interactions. However, temporal and spatial trends in wolf mortality, including direct and indirect persecution, were never summarized. This study aims to fill this gap by focusing on the situation of Tuscany and Emilia-Romagna re...

Marmora’s Warbler ( Curruca sarda ) and Balearic Warbler ( C. balearica ) are allopatric sibling species and were recently split mostly based on morphological and ethological characteristics. Here we provide the first phylogenetic and phylogeographic analyses of this species complex to support the taxonomic status of C. sarda and C. balearica in li...

Full-text available
Introgressive hybridization between domestic dogs and wolves (Canis lupus) represents an em-blematic case of anthropogenic hybridization and is increasingly threatening the genomic integrity of wolf populations expanding into human-modified landscapes. But studies formally estimating prevalence and accounting for imperfect detectability and uncerta...
Article
Full-text available
Dog domestication is still largely unresolved due to time-gaps in the sampling of regions. Ancient Italian canids are particularly understudied, currently represented by only a few specimens. In the present study, we sampled 27 canid remains from Northern Italy dated between the Late Pleistocene and Bronze Age to assess their genetic variability, a...

The grey wolf (Canis lupus) is one of the most widely distributed mammals in which a variety of distinct populations have been described. However, given their currently fragmented distribution and recent history of human-induced population decline, little is known about the events that led to their differentiation. Based on the analysis of whole ca...

This case report describes the rescue of an eight-month-old male Italian wolf (Canis lupus italicus), the victim of a car accident that caused it a pulmonary contusion, a fracture of the shaft of right femur, and a metaphyseal fracture of the left stifle. A lateral surgical approach was performed to treat the animal’s multiple contusions and fractu...

Anthropogenic hybridization is recognized as a major threat to the long-term survival of natural populations. While identifying F1 hybrids might be simple, the detection of older admixed individuals is far from trivial and it is still debated whether they should be targets of management. Examples of anthropogenic hybridization have been described b...

Globally, large carnivore livestock predations are major causes of conflicts with humans, thus identifying hotspots of carnivore attacks is fundamental to reduce the impact of these, and hence promote coexistence with humans. Species distribution models combining predictor variables with locations of predation events instead of species occurrences...

The survival of indigenous European wildcat (Felis silvestris silvestris) populations can be locally threatened by introgressive hybridization with free-ranging domestic cats. Identifying pure wildcats and investigating the ancestry of admixed individuals becomes thus a conservation priority. We analyzed 63k cat Single Nucleotide Polymorphisms (SNP...

Full-text available
Faecal non-invasive genetic sampling is one of the most practicable, ethical and applied tools to investigate the biology and the ecology of elusive or endangered mammal populations. However, the reliability, accuracy and effectiveness of this technique may be deeply conditioned by several factors such as climate, habitat characteristics, seasonali...
Article
Full-text available
Anthropogenic hybridization is widely perceived as a threat to the conservation of biodiversity. Nevertheless, to date, relevant policy and management interventions are unresolved and highly convoluted. While this is due to the inherent complexity of the issue, we hereby hypothesize that a lack of agreement concerning management goals and approache...

Background: The contemporary Italian wolf (Canis lupus italicus) represents a case of morphological and genetic uniqueness. Today, Italian wolves are also the only documented population to fall exclusively within the mitochondrial haplogroup 2, which was the most diffused across Eurasian and North American wolves during the Late Pleistocene. Howeve...

During historical times many local grey wolf (Canis lupus) populations underwent a substantial reduction of their sizes or became extinct. Among these, the wolf population once living in Sicily, the biggest island of the Mediterranean Sea, was completely eradicated by human persecution in the early decades of the XX century. In order to understand...

1. Estimating the relative abundance (prevalence) of different population segments is a key step in addressing fundamental research questions in ecology, evolution and conservation. The raw percentage of individuals in the sample (naive prevalence) is generally used for this purpose, but it is likely to be subject to two main sources of bias. First...

The distribution of intraspecific genetic variation and how it relates to environmental factors is of increasing interest to researchers in macroecology and biogeography. Recent studies investigated the relationships between the environment and patterns of intraspecific genetic variation across species ranges but only few rigorously tested the rela...
Article
The origin and the genetic uniqueness of the Italian grey wolf (Canis lupus italicus) have been the subject of several stud- ies. Recent works describe the spatial-temporal distribution of 2 ecomorphs, one of which (HG2), associated to Pleistocene megafauna, was dominant in Europe and America during the last glacial maximum (LGM). After the followi...

Background Genomic methods can provide extraordinary tools to explore the genetic background of wild species and domestic breeds, optimize breeding practices, monitor and limit the spread of recessive diseases, and discourage illegal crossings. In this study we analysed a panel of 170k Single Nucleotide Polymorphisms with a combination of multivari...
Conference Paper
Introduction - Anthropogenic hybridization is increasingly studied as serious conservation threat for the genetic integrity of local populations although the detection of hybrids or backcrosses is often far from trivial. We developed an effective workflow to detect different levels of genetic introgression, by using empirical and simulated data fro...
Article
Full-text available
Wolf-dog hybridization is considered as one of the main threats for wolf conservation since the admixture and introgression of domestic genes may disrupt local adaptations and threaten the long term survival of wild wolf populations. We investigated the occurrence of wolf-dog hybridization in Croatia by analyzing a panel of 12 autosomal microsatell...

Full-text available
The Italian wolf population, close to extinction in the mid-19th century, now counts about 1800 individuals. Its ongoing expansion raises social conflicts, especially in agricultural and semi-urbanized areas. Thus, monitoring wolf distribution, abundance and impact on the farming economy is a priority for conservation. We analysed canid DNA from 57...
Conference Paper
Camera trapping (CT) and non-invasive genetic sampling (NGS) are tools commonly used to obtain missing information on wild populations of rare/elusive carnivores while minimizing disturbance. These approaches are usually implemented separately, but their integration can become very useful when the achievement of both genetic and morphological data...
Article
Full-text available
Through thousands of years of breeding and strong human selection, the dog (Canis lupus familiaris) exists today within hundreds of closed populations throughout the world, each with defined phenotypes. A singular geographic region with broad diversity in dog breeds presents an interesting opportunity to observe potential mechanisms of breed format...

We investigated the structure and livestock predation patterns of a wolf population living in a portion of the Molise region. Although in the study area livestock damages have been well documented, data on wolf abundance and population dynamics are scarce and mostly indirectly extrapolated. We applied a multidisciplinary approach based on camera-tr...
