Available in PDF, EPUB and Kindle. Book excerpt: Les modes de déplacement des organismes et de connexion des populations sont déterminants dans la démographie et la survie des espèces. Cependant, chez les organismes marins, les événements de dispersion s'effectuent souvent lorsqu'ils sont dans une phase microscopique, difficile à observer directement. De nombreuses méthodes ont été développées pour les suivre ou les estimer à différentes échelles de temps et d'espace sans perturber l'écosystème. Elles ont été élaborées dans des domaines de recherches divers, allant de l'océanographie physique à la biogéochimie, en passant par la génétique des populations, le radio tracking, etc. Toutefois, aucune méthode ne réunit à elle seule les informations nécessaires à une vision d'ensemble de ces "mouvements du vivant". Il convient donc d'intégrer ces approches pour mieux prendre en compte la connectivité dans la gestion des aires marines protégées ou des ressources exploitées. Destiné aux gestionnaires et aux décideurs, cet ouvrage examine la puissance, les limites et les complémentarités de ces différentes techniques, afin d'optimiser leur mise en oeuvre pour la protection de la biodiversité marine.

Book Synopsis La protection de la biodiversité marine en droit international by : Karolina Zakovska
Download or read book La protection de la biodiversité marine en droit international written by Karolina Zakovska and published by . This book was released on 2015 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les océans représentent à eux seuls plus de 90% de la biosphère; la vie y foisonne sous d'innombrables formes interagissant les unes avec les autres. Cette diversité est essentielle pour l'intégrité des écosystèmes marins qui, à leur tour, fournissent des services fondamentaux à l'humanité. Or, la diversité de la vie dans les océans est menacée par le comportement irresponsable de l'Homme entraînant la pollution du milieu marin, la destruction des habitats et la surexploitation des ressources marines vivantes. Vu la discordance entre les caractéristiques naturelles des océans (notamment l'homogénéité relative du milieu marin) et leur régime juridique fragmenté, une action au niveau international prenant en compte la complexité des écosystèmes marins est nécessaire pour faire face aux dangers encourus par la biodiversité marine. Une telle action est toutefois compliquée par le caractère disparate du droit international dans ce domaine. Évoluant de façon ad hoc en réaction aux problèmes particuliers identifiés par les scientifiques, le droit international perçoit les divers organismes marins soit comme des ressources naturelles, soit comme des composantes menacées de la nature, et les soumet ainsi à des règles et institutions différentes. Cette disparité n'empêche pas une action efficace au profit de la biodiversité marine à condition toutefois que les acteurs compétents respectent les principes généraux du droit de l'environnement. Ces derniers permettent en effet de surmonter le caractère disparate du droit international en créant un cadre général d'harmonisation au sein duquel le rôle de toutes les institutions existantes serait respecté et leurs efforts au profit de la biodiversité marine se renforceraient mutuellement.

Available in PDF, EPUB and Kindle. Book excerpt: Écrit par un grand connaisseur des fonds marins, ce livre bouscule bien des idées reçues sur les atteintes à la biodiversité marine et sur sa protection. En prenant pour exemple la Méditerranée, une évaluation assez révolutionnaire des impacts est présentée. L’originalité de cette approche repose sur la distinction des atteintes à la biodiversité de celles préjudiciables pour l’Homme. Cela conduit à mettre en évidence les plus nocives pour la vie marine afin d’en améliorer les dispositifs de protection. Cet essai révèle aussi à quel point les outils juridiques déployés pour défendre les espèces menacées et les espaces naturels doivent être réformés. Il est fort probable qu’au cours des décennies à venir les effets du changement climatique global et les introductions d’espèces bouleverseront la biodiversité. Cependant la Méditerranée, les mers et les océans de la planète reste-ront bien vivants, mais différents. Alexandre Meinesz est un biologiste marin, plongeur et naturaliste, professeur émérite à l’université Côte d’Azur-laboratoire CNRS « Ecoseas » . Spécialiste de la végétation sous-marine, il a été le lanceur d’alerte sur l’invasion de l’algue Caulerpa taxifolia qui a défrayé la chronique dans les années 1990. Il est l’auteur du Roman noir de l’algue tueuse et de How Life Began : Evolution’s Three Geneses (Comment la vie a commencé : les trois genèses du vivant).

Available in PDF, EPUB and Kindle. Book excerpt: Narratology has been conceived from its earliest days as a project that transcends disciplines and media. The essays gathered here address the question of how narrative migrates, mutates, and creates meaning as it is expressed across various media. Dividing the inquiry into five areas: face-to-face narrative, still pictures, moving pictures, music, and digital media, Narrative across Media investigates how the intrinsic properties of the supporting medium shape the form of narrative and affect the narrative experience. Unlike other interdisciplinary approaches to narrative studies, all of which have tended to concentrate on narrative across language-supported fields, this unique collection provides a much-needed analysis of how narrative operates when expressed through visual, gestural, electronic, and musical means. In doing so, the collection redefines the act of storytelling. Although the fields of media and narrative studies have been invigorated by a variety of theoretical approaches, this volume seeks to avoid a dominant theoretical bias by providing instead a collection of concrete studies that inspire a direct look at texts rather than relying on a particular theory of interpretation. A contribution to both narrative and media studies, Narrative across Media is the first attempt to bridge the two disciplines.

Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Coastal and Estuarine Studies, Volume 61. The effects of increased atmospheric carbon dioxide and related climate change on shallow coral reefs are gaining considerable attention for scientific and economic reasons worldwide. Although increased scientific research has improved our understanding of the response of coral reefs to climate change, we still lack key information that can help guide reef management. Research and monitoring of coral reef ecosystems over the past few decades have documented two major threats related to increasing concentrations of atmospheric CO2: (1) increased sea surface temperatures and (2) increased seawater acidity (lower pH). Higher atmospheric CO2 levels have resulted in rising sea surface temperatures and proven to be an acute threat to corals and other reef-dwelling organisms. Short periods (days) of elevated sea surface temperatures by as little as 1–2°C above the normal maximum temperature has led to more frequent and more widespread episodes of coral bleaching-the expulsion of symbiotic algae. A more chronic consequence of increasing atmospheric CO2 is the lowering of pH of surface waters, which affects the rate at which corals and other reef organisms secrete and build their calcium carbonate skeletons. Average pH of the surface ocean has already decreased by an estimated 0.1 unit since preindustrial times, and will continue to decline in concert with rising atmospheric CO2. These climate-related Stressors combined with other direct anthropogenic assaults, such as overfishing and pollution, weaken reef organisms and increase their susceptibility to disease.

Book Synopsis The Role of Integrity in the Governance of the Commons by : Laura Westra
Download or read book The Role of Integrity in the Governance of the Commons written by Laura Westra and published by Springer. This book was released on 2017-05-29 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the impact of disintegrity on various aspects of governance, as the disregard of ecological conditions produce grave direct effects to human rights (to water or food) and, indirectly, also to human security in several ways. International legal regimes need to be reconsidered and perhaps re-interpreted, in order to correct these situations that affect the commons today. Some believe that our starting point should acknowledge the impact we already have on the natural world, and accept that we now live in the "anthropocene". Others think that the present emphasis on sustainable development needs to be re-defined. Finally, many believe that reconnecting with moral principles both in professional life and in governance in general represents a necessary first step.
Book Synopsis Marine Animal Forests by : Sergio Rossi
Download or read book Marine Animal Forests written by Sergio Rossi and published by Springer. This book was released on 2017-08-15 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last decades there has been an increasing evidence of drastic changes in marine ecosystems due to human-induced impacts, especially on benthic ecosystems. The so called “animal forests” are currently showing a dramatic loss of biomass and biodiversity all over the world. These communities are dominated by sessile suspension feeder organisms (such as sponges, corals, gorgonians, bivalves, etc.) that generate three-dimensional structures, similar to the trees in the terrestrial forest. The animal forest provide several ecosystem services such as food, protection and nursery to the associated fauna, playing an important role in the local hydrodynamic and biogeochemical cycles near the sea floor and acting also as carbon sinks. The present book focus its attention on these three dimensional animal structures including, for the first time, all the different types of animal forests of the world in a single volume.
