Definitions of Marine protected areas (MPAs) vary from exclusionary to inclusionary. A recently revised IUCN definition of what constitutes a protected area (PA) emphasizes the conservation purpose of geographical space. ‘‘Conservation’’ is defined as the in situ maintenance of ecosystems and natural and semi-natural habitats and of viable populations of species in their natural surroundings. Prohibition or restriction of activities within a PA is usually part of the in situ maintenance. For marine sites this engenders unique management opportunities and challenges.
Temporal trends indicate that overexploitation and habitat loss have been the main human drivers of historical changes in Mediterranean biodiversity. At present, habitat loss and degradation, followed by fishing impacts, pollution, climate change, eutrophication, and the establishment of alien species are the most important threats and affect the greatest number of taxonomic groups. All these impacts are expected to grow in importance in the future, especially climate change and habitat degradation. Marine experts and conservationists see great hope in the opportunities provided by MPAs to counter threats to marine ecosystems. In this book, the effects of the MPAs are illustrated based on detailed analyses of the recent case studies of Mediterranean charismatic species, like monk seal, dolphins, groupers, seagrass meadows and birds. This book examines the use of MPAs as a way to restore and maintain healthy marine environments by contributing to the overall protection of critical marine habitats and resources in Mediterranean. It suggest the best way to manage the existing ones after providing case studies showing the actual situation of them and how to establish the future MPAs in the Mediterranean. This book is the precious instrument, full of conservation strategies based on MPA networks aimed at enhancing resilience and it may be the most effective tool to limit the negative impacts of the complex suites of threats on marine ecosystems under future scenarios of frequent and/or persistent disturbance.

- The impact of environmental gradients and human activities on marine biodiversity.
- The effectiveness of varying degrees of protection in MPAs on fish biomass and habitat stability.
- Connectivity patterns in MPAs and their role in the recruitment of exploited species like the dusky grouper.
- Social and economic impacts of marine park establishment on coastal human populations.
- Conservation challenges and strategies regarding transboundary endangered species.
Auszug aus dem Buch
Introduction to Mare mediterraneum
The Mare mediterraneum (in Latin) describes the Mediterranean as a ‘‘sea in the middle of the land.’’ This basin is the largest (2,969,000 km2) and deepest (average 1,460 m, maximum 5,267 m) enclosed sea on Earth (Figure 1a). Situated at the crossroads of Africa, Europe, and Asia, the Mediterranean coasts have witnessed the flourishing and decline of many civilizations. The region was an important route for merchants and travelers of ancient times, allowing for trade and cultural exchange, and today it is notable for contributions to global economy and trade. Its coasts support a high density of inhabitants, distributed in 21 modern states, and it is one of the top tourist destinations in the world, with 200 million tourists per year (National Oceanic and Atmospheric Administration, 2009).
The Mediterranean Sea connects through the Strait of Gibraltar to the Atlantic Ocean in the west and through the Dardanelles to the Sea of Marmara and the Black Sea in the northeast. In the southeast, the Suez Canal links the Mediterranean to the Red Sea and the Indian Ocean (Figure 1a).
Summary of Chapters
Chapter 1 Mediterranean Sea Biodiversity: An overview of the Mediterranean as a biodiversity hotspot, detailing species estimates, threats like pollution and alien species, and spatial patterns of richness.
Chapter 2 The Perspective for Marine Conservation in the Mediterranean Sea: Examines the taxonomy of 117 Mediterranean MPAs and their relationship with cumulative human impacts.
Chapter 3 Mediterranean Conservation Implications based on Environmental and Human Gradients: Establishes a baseline for rocky reef ecosystem structure and evaluates the effectiveness of different MPA management levels.
Chapter 4 MPAs Posidonia oceanica Meadows Health Indicate that Legal Protection is not Enough: Analyzes the health of Posidonia oceanica meadows in relation to anthropization, concluding that legal protection is insufficient without broader management.
Chapter 5 Evidences from a Mediterranean MPA Show that Protection Enhances Community and Habitat Stability: Demonstrates that protection increases resistance and resilience in coastal assemblages, reducing temporal variability.
Chapter 6 Fish Biodiversity and Fisheries in Mediterranean MPAs: Explores the spatial congruence between fish biodiversity hotspots, fishing pressure, and existing MPAs.
Chapter 7 The Recent Case Study about Dusky Grouper (Epinephelus marginatus) Indicate Low Connectivity between Mediterranean MPAs: Uses a biophysical model to assess connectivity and larval dispersal for the dusky grouper, highlighting a lack of a well-connected network.
Chapter 8 Response of Rocky Reef Top Predators (Serranidae: Epinephelinae) in and Around MPAs: Evaluates the response of grouper populations to protection and the presence of biomass gradients across reserve boundaries.
Chapter 9 Species-Specific Export of Fish Naïveté from a No-Take Marine Protected Area in a Coastal Recreational Hook and Line Fishery: Investigates the behavioral differences in fish vulnerability to fishing gear in and around MPAs.
Chapter 10 Marine Protected Area or marine polluted area? The case study of the striped dolphin (Stenella coeruleoalba): Applies a multidisciplinary tool to assess toxicological stress in striped dolphins within the Pelagos Sanctuary.
Chapter 11 Transboundary Conservation Efforts Are Needed for the Critically Endangered Species like Balearic Shearwater: Details the distribution and conservation needs of the critically endangered Balearic shearwater, emphasizing the necessity of transboundary efforts.
