New trends for eliminating land-based pollution in the Mediterranean Sea
2002
En este capítulo estudio todos los instrumentos para la protección del medio marino, tanto políticos como jurídicos, adoptados a escala mediterránea con motivo de la revisión llevada a cabo en el vigésimo aniversario del Plan de Acción para el Mediterráneo. El análisis lo centro en las disposiciones de todos estos instrumentos relativas a la eliminación de la contaminación de origen terrestre en el Mar Mediterráneo. In this chapter, I study all political and legal instruments for the protection of the marine environment, adopted at a Mediterranean level in the twenty anniversary of the Mediterranean Action Plan. In particular, I analysis the provisions of all these instruments concerning th…
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…

Automated Plankton Classification With a Dynamic Optimization and Adaptation Cycle
2022
With recent advances in Machine Learning techniques based on Deep Neural Networks (DNNs), automated plankton image classification is becoming increasingly popular within the marine ecological sciences. Yet, while the most advanced methods can achieve human-level performance on the classification of everyday images, plankton image data possess properties that frequently require a final manual validation step. On the one hand, this is due to morphological properties manifesting in high intra-class and low inter-class variability, and, on the other hand is due to spatial-temporal changes in the composition and structure of the plankton community. Composition changes enforce a frequent updating…
Unveiling the Relationship Between Sea Surface Hydrographic Patterns and Tuna Larval Distribution in the Central Mediterranean Sea
2021
Thunnus thynnus (Atlantic bluefin tuna, ABT) and other tuna species reproduce in the Mediterranean Sea during the summer period. Despite the Central Mediterranean Sea, the Strait of Sicily in particular, being a key spawning site for many tuna species, little is known on the effects of oceanographic variability on their larval distribution in this area. The abundance and presence-absence of larval specimens for three tuna species (ABT, bullet tuna and albacore) were modeled in order to examine their relationships with environmental factors, by analysing historical in situ information collected during seven annual surveys (2010–2016). The results revealed that most tuna larvae for the three …
