Citizen science: a successful tool for monitoring biodiversity in Marine Protected Areas
2018
In the last few decades, anthopogenic activities, introduction of Non-Indigenous Species (NIS, i.e. organisms introduced outside of their natural range), and climate changes, have significantly affected Mediterranean marine biodiversity and ecosystem functioning (Coll et al., 2010). All that is also true for Marine Protected Areas (MPAs), whose major aim is biodiversity conservation. Therefore, monitoring and surveillance plans are strongly needed, and the creation of public awareness campaigns might be effective tool to plan effective management and conservation strategies in MPAs. Since intensive monitoring programs could be very expensive, citizen science, the involvement of citizens in …
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…
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 …
Integrating natural capital assessment and marine spatial planning: A case study in the Mediterranean sea
2017
Abstract Marine and coastal ecosystems are among the most productive environments in the world and their stocks of natural capital offer a bundle of vital ecosystem services. Anthropogenic pressure seriously threatens health and long-term sustainability of marine environments. For these reasons, integrated approaches capable of combining ecological and socio-economic aspects are needed to achieve nature conservation and sustainability targets. In this study, the value of natural capital of the Egadi Islands Marine Protected Area (EI-MPA) was assessed through a biophysical and trophodynamic environmental accounting model. The emergy value of both autotrophic and heterotrophic natural capital…
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.
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…
