Biodiversity Of Oceans And Seas

In Biodiversity of Oceans and Seas, you will discover: Oceans and seas cover about 70 percent of the Earth's surface, and are home to hundreds of thousands of marine species Oceans and seas are threatened by overfishing, pollution from oil and plastics, and climate change The Red Sea, in between Africa and Asia, is home to more than 1,600 animal species, and human activities are the greatest threat to its biodiversity. Greg Pyers worked as an educator in zoos and as a school teacher before becoming a full-time writer. He has written many conservation themed children's book and has won several environmental literature awards. Book jacket.

Ecosystems and Biodiversity in Deep Waters and High Seas outlines a number of options for the conservation and sustainable management of the deep seas and open oceans, including actions and measures that reflect an integrated approach to oceans management based on "ecological boundaries" rather than just political ones, giving higher levels of protection to vulnerable species like deep sea fish as well as to biologically and ecologically significant ecosystems such as cold water corals and hydrothermal vent communities.

'Marine Conservation Biology' brings together leading experts from around the world to apply the lessons and thinking of conservation biology to marine issues. The contributors cover what is threatening marine biodiversity and what humans can do to recover the biological integrity of the world's oceans.

This volume examines the deep sea ecosystem from a variety of perspectives. The initial chapters examine the deep-sea floor, the deep pelagic environment and the more specialised chemosynthetic environments of hydrothermal vents and cold seeps. These environments are examined from the perspective of the relationship of deep-sea animals to their physico-chemical environment. Later chapters examine the biogeography of the main deep oceans (Atlantic, Pacific and Indian) with particular attention to the downward flux of surface-derived organic matter and how this drives the processes within the deep-sea ecosystem. The peripheral deep seas including the polar seas and the marginal deep seas (inter alia the Mediterranean, Red, Caribbean and Okhotsk seas) are explored in the same context. The final chapters examine the processes occurring in the deep sea and include an analysis of why the deep sea has high species diversity, how the fauna respond to organic input and how species have adapted reproductive activity in the deep sea. The volume concludes with an analysis of the anthropogenic impact on the deep sea.

The Southern Ocean surrounding the Antarctic continent is vast, in particular, its history, its isolation, and climate, making it a unique "laboratory case" for experimental evolution, adaptation and ecology. Its evolutionary history of adaptation provide a wealth of information on the functioning of the biosphere and its potential. The Southern Ocean is the result of a history of nearly 40 million years marked by the opening of the Straits south of Australia and South America and intense cooling. The violence of its weather, its very low temperatures, the formation of huge ice-covered areas, as its isolation makes the Southern Ocean a world apart. This book discusses the consequences for the evolution, ecology and biodiversity of the region, including endemism, slowed metabolism, longevity, gigantism, and its larval stages; features which make this vast ocean a "natural laboratory" for exploring the ecological adaptive processes, scalable to work in extreme environmental conditions. Today, biodiversity of the Southern Ocean is facing global change, particularly in regional warming and acidification of water bodies. Unable to migrate further south, how will she cope, if any, to visitors from the North? Designed for curious readers to discover the immense ocean surrounding the most isolated and most inhospitable continent on the planet. Describes the Southern Ocean facing biodiversification due to global change Authored by scientists with experience of expeditions to the Southern Ocean

The first edition of The Living Ocean, published in 1991 by Island Press in association with Friends of the Earth, was widely praised by scientists, policymakers, instructors, and general readers as a useful and accessible introduction to the science and policy of biological diversity in marine environments. Since that time, much new research has been conducted and numerous national and international policy initiatives have been undertaken.With 1998 designated by the United Nations as the International Year of the Ocean, this new, revised and expanded, edition is a welcome and much-needed addition to the literature.This edition brings the volume up-to-date, and re-establishes it as an essential primer for anyone wishing to gain an understanding of marine biodiversity and how it can be protected. It provides an overview of basic concepts and principles and a review of relevant policy issues and existing instruments. The author:defines biological diversity and discusses the importance of threats to marine biodiversity reviews the current status of scientific knowledge describes the major coastal and oceanic ecosystem types and addresses the major threats in each presents a general discussion of the ways in which government and the public can protect marine biological diversity provides specific examples of national and international policies, legal instruments, programs, and institutions addresses how social, economic, political, and ethical considerations affect decisions to conserve marine biological diversity considers the involvement of citizens in developing ocean policy The book also includes a useful glossary that provides information about basic biological concepts, and a comprehensive bibliography. Throughout, the author emphasizes the relationship of human societies and governments to the living ocean, and the need to implement programs that will protect ecosystems and species.

Marine Biodiversity of Areas beyond National Jurisdiction (BBNJ) identifies the major issues at stake in the BBNJ negotiations and examines the conservation and sustainable use of marine biological diversity of areas beyond national jurisdiction. This timely volume offers cutting edge contributions from leading global experts on access and benefit sharing of marine genetic resources; environmental impact assessments; capacity building and transfer of technology as well as Arctic environmental issues including security and shipping. Cross-cutting themes including the potential impact on existing legal frameworks and instruments are also explored.
