Marine Genetic Resources 1
Advances in research and development reveal the immense diversity and potential of marine genetic resources. Under international law, no specific regime applies to these complex and paradoxical objects of use. The Law of the Sea Convention sets a framework that is partly inadequate for this new category of resources. The Biodiversity Convention and the Nagoya Protocol only address the genetic resources of national areas. Patents allow their holder to exercise a monopoly on exploiting biotechnological creations to extensive claims, questioning the common nature of biodiversity and related knowledge. They hinder research and the objectives of biodiversity law. The legal and practical rules of physical and functional access vary in geometry. They focus on the valorization of research results, crystallizing conflicts of interest between suppliers and users. Sustainable research and development is essential to the knowledge and protection of marine biodiversity. The qualification of marine genetic resources in common, standard contractual tools, distributed research and development infrastructures, negotiation of an agreement on sustainable use and conservation of biodiversity beyond the limits of national jurisdiction, would To remove these inconsistencies.
Fishes in Lagoons and Estuaries in the Mediterranean. Diversity, Bioecology and Exploitation
Lagoons and estuaries are transition spaces between earth and sea. Beyond their expanse, geographic repartition, geomorphological, hydroclimatic and ecobiological diversity and biodiversity, they play an important role in regional economies and are some of the ecosystems most vulnerable to global change. Reinforced by numerous references, this book studies Mediterranean lagoonal and estuarine fishes whose diversity largely depends on the composition of neighboring marine and continental ichtyofauna. The authors describe their morphological, biological, ecological and behavioral characteristics by evoking their distinctive features and differences with their marine or freshwater homologues. Their adaptation strategies, elucidated thanks to recent advances in morphology, genetics and molecular biology, are recognized as a major advantage in the context of climate change. This book is for natural environment managers, engineers, teachers, students and researchers.
