Is Citizen Science a valid tool for monitoring alien species in Marine Protected Areas?
2020
We report on our experience of NIS monitoring within the Egadi Islands MPA and at Pianosa Island National Park of Tuscan Archipelago through Citizen Science projects The Projects Caea cdacea Egadi Islands and Aliens in the Sea allowed to gather useful information on the distribution and colonisation strategies of NIS and cryptogenic species within the Egadi Islands MPA The project Percorsi nel bluBlue Paths allowed to register the first record of two cryptogenic species, Aa dacea Rang, and Pec gbbe H Milne Edwards, , at Pianosa Island As in MPAs the protection does not hinder the introduction and spreading of NIS, we expect they are likely to continue to arrive and expand in the absence of …
Social equity and marine protected areas: Perceptions of small-scale fishermen in the Mediterranean Sea
2020
Abstract Global conservation policy requires the scaling up of effectively and equitably managed networks of marine protected areas (MPAs). While progress has been made on spatial coverage, the fundamental aspects of effectiveness and equity are falling short. Past research has focused on management effectiveness in MPAs, but less attention has been given to social equity though it is an ethical imperative and instrumental to conservation. This study assessed the perceptions of SSF regarding recognitional, procedural and distributional dimensions of social equity using quantitative surveys in 11 MPAs across 6 countries on the Mediterranean Sea. To do so, we developed individual indicators f…

ARE MARINE PROTECTED AREAS (MPAs) EFFECTIVE IN PROTECTING FROM INVASIVE SPECIES? THE CASE STUDY OF CAULERPA CYLINDRACEA SONDER (CAULERPALES, CHLOROPH…
2019
The main purpose of Marine Protected Areas (MPAs) is biodiversity conservation. The effects that invasive species have on MPAs, and vice versa, are still not completely known, even though their assessment is crucial for MPA management and conservation purposes. In this respect, monitoring plans are essential and the involvement of citizen scientists may be fundamental. Our experience of Caulerpa cylindracea Sonder 1845 monitoring within the Egadi Islands MPA highlighted that the alga is widespread within the MPA, mainly at Favignana Island, also threatening valuable habitats such as vermetid reef and coralligenous formations. Moreover, Favignana is the island of the Aegadian archipelago mos…
A review of methods to assess connectivity and dispersal between fish populations in the Mediterranean Sea
2013
Fish populations are linked to each other via dispersal of individuals as eggs, larvae, juveniles or adults. The understanding of this process, known as connectivity, has a pivotal role for the management of overexploited fish stocks and the development of accurate conservation strategies. Knowledge on connectivity and fish movements is considered fundamental toward the correct design of marine protected area (MPA) networks for the achievement of the benefits of protection. Connectivity patterns are still largely unknown worldwide. A general lack of knowledge is particularly evident for the Mediterranean Sea where few studies dealing with this topic have been carried out and some methods, c…
Marine protected areas overall success evaluation (MOSE): A novel integrated framework for assessing management performance and social-ecological ben…
2020
International audience; Characterized by interlinked social, economic, and ecological dynamics, Marine Protected Areas (MPAs) are a management tool for achieving sustainability goals in social-ecological systems. The recent increase in their establishment worldwide, fostered by international policies, highlights the need for comprehensive and integrated assessment frameworks able to address the evaluation of their social-ecological effectiveness and management performance, which is of fundamental importance for their adaptive management and decision making processes. Although several indicators and methodologies exist to assess MPAs ecological or social performances, no comprehensive assess…
First record of the invasive crab Percnon gibbesi (H. Milne Edwards) at Pianosa Island: the second goal reached by the innovative Marine Citizen Scie…
2020
This study represents the second scientific goal reached by the operating Project Team and the first record of the cryptogenic species Pec gbbe H Milne Edwards, at Pianosa Island October During a Scuba survey, almost specimens of P gbbe were recorded up to a depth of m and analyzed, according to some indicators such as health state, sex, morphology, and parameters such as temperature, covering of algal species, type of rocky bottom This tropical Atlantic grapsid crab is considered as the most invasive decapod currently expanding its distribution in the Mediterranean Sea.
Non-Indigenous Species (NIS) within Marine Protected Areas (MPAs). The case study of the Aegadian Islands MPA (Sicily, Tyrrhenian Sea) and the Dwejra…
2018
The introduction of non-indigenous species (NIS) has been pointed out as a major threat to biodiversity. NIS may become invasive alien species (IAS) and may cause biodiversity loss and ecosystem service changes. In the Mediterranean Sea, Sicily and surrounding islands, also including a high number of Marine Protected Area (MPAs), as a consequence of their geographic position and the intense maritime traffic, is a region particularly vulnerable and prone to NIS invasions. Since frontiers do not exist in the sea, biological invasions may severely affect MPAs, whose major aim is biodiversity conservation. Among the Sicilian MPAs, the Aegadian Islands MPA report the highest number of NIS (19). M…
Native predators control the population of an invasive crab in no-take marine protected areas
2018
1. The resistance of an ecosystem to species invasion is considered to be related to the abundance and diversity of native species i.e. biotic resistance hypothesis). Theory predicts that the high native diversity in pristine systems can hinder the establishment and/or the spread of non‐native species through direct and indirect mechanisms (e.g. through competitive and/or predatory interactions). 2. Here we tested whether predation provides higher resistance to invasion by the Percnidae crab Percnon gibbesi (H. Milne Edwards, 1853) in protected native communities, compared with exploited ones. Specifically, this study aimed to compare: (i) the abundance and diversity of potential predator a…
