Cultural and socio-economic impacts of Mediterranean marine protected areas
2000
Marine protected areas (MPAs) may be important for protecting the marine environment, but they may also have substantial socio-cultural impacts about which very little is currently known, or acknowledged. In the Mediterranean, few data are available on the socio-economic consequences of MPAs. The present study reviews the existing data on MPAs in Spain, France, Italy and Greece. A general increase in tourist activities in Mediterranean MPAs is evident, as are increases in the abundances of larger fish species, although there are no data indicating yields for fisheries increase adjacent to MPAs. A large increase in the number of divers and vessels using MPAs has already had impacts on natura…
Connected Lands : new perspectives on Ecological Networks Planning
2017
The construction of an ecological network is a fairly complex operation, given that the components to be considered are strictly linked to the age-old problem of the relationship between man and the land, until now perhaps seen too much as a limiting relationship and not, as the use of this tool suggests, as a relationship to be safeguarded. It may represent the ideal way to reconcile human needs and the conservation of biodiversity for the sustainable management of land. This study on the ecological network represents a tool capable to contain habitat fragmentation trough a new perspective that integrates theoretical approaches and methods with planning models and experiences of local appl…
Dispersal of larval and juvenile seabream: Implications for Mediterranean marine protected areas
2015
International audience; In the marine context, information about dispersal is essential for the design of networks of marine protected areas (MPAs). Generally, most of the dispersal of demersal fishes is thought to be driven by the transport of eggs and larvae in currents, with the potential contribution of dispersal in later life stages relatively minimal.Using otolith chemistry analyses, we estimate dispersal patterns across a spatial scale of approximately 180 km at both propagule (i.e. eggs and larvae) and juvenile (i.e. between settlement and recruitment) stages of a Mediterranean coastal fishery species, the two-banded seabream Diplodus vulgaris. We detected three major natal sources …
Fire in Protected Areas - the Effect of Protection and Importance of Fire Management
2012
Fires are important but socially and economically unwanted disturbances of the ecosystems. They cannot be considered as a problem, they are global phenomena. Protected areas are created to protect biodiversity, and strict protection is often applied, forgetting that fire had shaped that that we aim to protect. This harsh protection is producing important changes in the protected habitats and is increasing their vulnerability to destructive wildfires. Thus, it is of major interest to incorporate fire management in the protected areas plan, including the (re)use of prescribed fire and traditional burning in order to reintroduce fire regimens, fundamental to the landscape sustainability. This …
IL CASO STUDIO DI ALCUNE PGM: IMPLICAZIONI PER LE SPECIE DI LEPIDOTTERI NON BERSAGLIO NELLE AREE PROTETTE SICILIANE
2012
La Sicilia è una delle regioni mediterranee con la maggior biodiversità faunistica e floristica la cui conservazione, potrà dipendere anche da un attento piano di valutazione del rischio derivante dall’introduzione di piante geneticamente modificate (PGM) sugli organismi non target. A tal fine sono state scelte due aree rappresentative di differenti habitat siciliani: il SIC “Raffo Rosso, Monte Cuccio e Vallone Sagana (ITA020023) e il SIC “Capo Gallo” (ITA020006). Sono stati individuati 5 habitat: Uliveto, Bosco misto, Ampelodesmeto, Macchia mediterranea e Macchia mediterranea costiera per valutare il potenziale rischio di introduzione di PGM Bt. La maggior parte della bibliografia sugli ef…
Improving marine protected area governance through collaboration and co-production.
2020
Marine protected areas (MPAs) socio-ecological effectiveness depends on a number of management and governance elements, among which stakeholder engagement and community support play key roles. Collaborative conservation initiatives that engage stakeholders in action research and knowledge co-production processes can enhance management and governance of MPAs. To design effective strategies aimed at reconciling biodiversity conservation and management of sustainable human uses, it is key to assess how local communities respond to such initiatives and identify the set of contextual factors, institutional, local and individual, potentially affecting these responses. This paper presents the appr…
Biodiversity conservation and protected areas in the Mediterranean region
2018
This chapter provides an overview of current biodiversity knowledge in Mediterranean forest ecosystems across all levels (genetic diversity, species diversity, landscape diversity) and endemism, ecological peculiarities that make Mediterranean forest ecosystems different. It also outlines the importance of biodiversity for functional forest ecosystems and illustrates some examples of conservation efforts in the region.
Monitoring of alien aquatic plants in the inland waters of Sicily (Italy)
2020
Updated and reliable data on the presence and distribution of alien aquatic plant species in Sicily are lacking, and there is a need to fill this gap for a proper and efficient management of freshwater ecosystems and biodiversity. This paper reviews the available knowledge about alien aquatic vascular plants in the inland waters of Sicily (Italy). The aim is to provide an updated checklist, as a first step in the study of the impact of those plants on the native species and ecosystems of this Mediterranean island. The paper focuses on the strictly aquatic species (hydrophytes), excluding emergent macrophytes. Four species were listed, all of them free-floating and with American origin. Most…
Hotspots of species richness, threat and endemism for terrestrial vertebrates in SW Europe
2011
The Mediterranean basin, and the Iberian Peninsula in particular, represent an outstanding “hotspot” of biological diversity with a long history of integration between natural ecosystems and human activities. Using deductive distribution models, and considering both Spain and Portugal, we downscaled traditional range maps for terrestrial vertebrates (amphibians, breeding birds, mammals and reptiles) to the finest possible resolution with the data at hand, and we identified hotspots based on three criteria: i) species richness; ii) vulnerability, and iii) endemism. We also provided a first evaluation of the conservation status of biodiversity hotspots based on these three criteria considerin…
