Introduction
I had a Ph.D. at the Polytechnic University of Marche in "Marine ecology and biology". My Ph.D. has been co-funded by the Cattolica Aquarium (Cattolica, RN, Italy). I'm working on sharks conservation in the Mediterranean Sea. Sharks seem to be at present time one of the rarest and elusive species in the area and new strategies need to take place. In that view, my project uses both historical ecology and genetics, and Citizen Science as tools for supporting data collection.

Article
In the last 50 yr, shark populations showed steep declines in the Mediterranean Sea. The IUCN lists most Mediterranean species as Endangered (55%), while considering 27.5% of them Data Deficient. Here, sharks are currently one of the rarest and more elusive groups of animals, and data from fisheries and scientific monitoring still insufficiently su...
Article
Sharks are threatened by several human activities that impact their distribution and abundance. A great proportion of shark captures happen as incidental capture (bycatch) by fisheries and in beach nets. Recent studies have focused on reducing these captures by exploiting technologies that target the sharks’ electrosensory system, obtaining contras...
Article

Species diversity assessments are an important step to evaluate the conservation status of a community, both in marine and terrestrial ecosystems. These assessments are pivotal if related to both, the constant increase of human pressure on ecosystems and the anthropogenic climate change occurring nowadays. Sharks and rays are globally threatened, a...
Article
Shark diving tourism is an activity that can contribute significantly to coastal economies, while also offering tremendous help to shark conservation efforts. Nevertheless, like any form of wildlife-based tourism, shark diving poses management challenges revolving around ethical and safety considerations. Safety in shark diving normally focuses on...
Article
Full-text available
The Mediterranean Large Elasmobranchs Monitoring (MEDLEM) database contains over 3000 records (more than 4000 individuals) of large elasmobranch species from 20 different countries around the Mediterranean and Black seas, observed from 1666 to 2017. The main species included in the archive are the devil fish (1 813 individuals), the basking shark (...
Article
1. Sharks are globally exposed to several anthropogenic threats, which, in many cases, have severely reduced their distribution and have impacted populations. In the Mediterranean Sea, because of its long history of exploitation and the relatively short span of scientific monitoring, reconstructing shark baselines is challenging. Many vulnerable sp...
Article
Full-text available
The Mediterranean Sea is a hotspot for shark conservation. A decline in large pelagic shark populations has been observed in this vast region over the last 50 years and a lack of data on the local population status of various species has been pointed out. Throughout history, the relation between people and sharks has been revolving around a mixture...
Article
1. The sand tiger shark (Carcharias taurus) is a coastal species distributed in temperate and sub-tropical waters, classified as “Vulnerable” at global level and “Critically endangered” in Eastern Australia, Southwestern Atlantic Ocean and Mediterranean Sea. Six populations (Northwestern Atlantic, Brazil, South Africa, Japan, Eastern Australia and...
Poster
Full-text available
Sharks represent one of the globally most endangered groups of fish, particularly in the Mediterranean Sea where 57% of the species are considered threatened by the IUCN. Occurrence sightings are increasingly scarcer in the area and targeted surveys are rare and limited to specific sectors. However new opportunities are emerging to exploit unconven...
Presentation
Full-text available
In the Mediterranean Sea, sharks are currently one of the less frequently observed groups of animals. Scientific surveys do not provide enough observation effort to collect relevant data on the presence and distribution of the species, and fisheries data have been historically scattered and rarely adequate in terms of taxonomic resolution. Followin...

Sharks are one of the most wanted group of animals that scuba divers would like to see underwater. Shark diving is an important part of the scuba diving market, with a relevant number of people travelling every year to have an underwater shark encounter. Southern Africa offers a wide number of opportunities to meet several shark species in the wild...

Nel poster sono descritti i comportamenti di uno squalo bamboo (Chiloscyllium punctatum) in presenza di campi elettromagnetici indotti. Le immagini mostrano la vasca per la sperimentazione, le fonti che generano campi elettromagnetici di differente intensità (un magnete e un trasformatore) e i percorsi che lo squalo effettua in presenza di queste f...
Presentation
Full-text available
Sharks are among the most endangered group of animals in the world, and in the Mediterranean Sea they have shown steep declines both in coastal and pelagic ecosystems. Of the 40 species of sharks occurring in the Mediterranean Sea, 57% are classified by the IUCN as threatened (vulnerable, endangered and critically endangered), of which 30% are crit...
Article
The green alga Dunaliella salina is a common inhabitant of crystallizers in solar saltworks. Although its presence has been associated with low salt quality, little is known about the mechanism through which Dunaliella causes such effect. It has been suggested that the release of organic matter from healthy D. salina cells interferes with NaCl crys...
