A species’ potential distribution can be modelled adequately only if no factor other than habitat availability affects its occurrences. Space use by stone marten Martes foina is likely to be affected by interspecific competition with the strictly related pine marten Martes martes , the latter being able to outcompete the first species in forested h...
Article
During spring migration, a few tens of thousands of European Honey-buzzards wintering in sub-Saharan Africa cross the central Mediterranean to reach their breeding grounds in central-eastern Europe. In so doing they concentrate passage through the Sicilian Channel but choose different flyways in response to different wind conditions. This study inv...

The Barbary partridge is one of the four species of Alectoris found in Mediterranean Basin. Its range is restricted to Sardinia, northwestern Africa, Gibraltar, and Canary Islands. It is classified as SPEC3 because its population is declining; nonetheless, its ecology is poorly known. Our aims were to define the habitat factors linked to the specie...
Article
The focal species approach claims that a landscape managed for the conservation of a set of focal species, each of which identified as the most threatened by specific processes, also protects all the other species. We investigated the effects of two practical issues of this approach: the problems with identifying the species most affected by threat...

During migration soaring birds select areas where they can successfully use atmospheric uplifts to gain altitude and reducing the amount of energy used for flapping flight. We analysed radar data collected on the Calabrian side of the Strait of Messina during three different spring seasons (2015-2017). This study aims to identify environmental ch...
Article
In temperate ecosystems, seasonality influences animal behaviour. Food availability, weather, photoperiod and endogenous factors relevant to the biological cycle of individuals have been shown as major drivers of temporal changes in activity rhythms and group size/structure of herbivorous species. We evaluated how diurnal female foraging activity a...
Article
Agroecosystems harbour common species besides farmland birds, which are often understudied because they are not appealing to researchers. However, common species are fundamental to the structure of most ecosystems, so if the preservation of an overall pattern of species richness is a valid conservation goal, we need to improve our knowledge of them...

To counteract the negative effects of forest fragmentation on wildlife it is crucial to maintain functional ecological networks. We identified the ecological networks for two mammals with very different degrees of forest specialization, the European badger Meles meles and the Roe deer Capreolus capreolus, by differentiating four agroforestry elemen...
Article
In recent decades, the establishment of plantations to produce biomass for energy, known as short rotation coppice (SRC), has been increasing in many countries in Europe. As with other tree plantations, these stands could enhance the structural diversity of intensively managed farmlands and consequently lead to an increase in animal diversity. In t...

We are carrying on a field research at the Strait of Messina (Southern Italy) using radar equipment and visual observations to collect data on bird migration both during day and night. The migration of birds at this site is relevant in spring as well as during autumn. During the day tens of thousands raptors are observed each season, while during the night the migratory flow of passerines is impressive. We are analysing the Influence of weather, time of the day, flock size and specie-specific differences on the migratory flow of birds.
