This book explores the ethnobiology of corals by examining the various ways in which humans, past and present, have exploited and taken care of coral and coralline habitats. This book will bring the educated general audience closer to corals by exploring the various circumstances of human-coral coexistence by providing scientifically sound and jargon-free perspectives and experiences from across the globe. Corals are a vital part of the marine environment since they promote and sustain marine and global biodiversity while providing numerous other environmental and cultural services. Countless valuable coral conservation efforts are published in academic and general audience venues on a daily basis. However relevant, few of these reports show a direct, deeper understanding of the intimate relationship between people and corals throughout the world’s societies. Ethnobiology of Corals and Coral Reefs establishes an intimate bond between the audience and the wonder of corals and their importance to humankind.
This document has been prepared by the Food and Agriculture Organization of the United Nations (FAO), in accordance with a request from CITES (CoP Decision 17.191 on Precious corals, for consideration at the 30th meeting of the Animals Committee). The report concerns precious (red, pink, white and black) coral species within the hexacoral order Antipatharia, and the octocoral family Coralliidae. According to the requirements of CITES Decision 17.191, the study considers all available data and information on the biology, population status, use and trade in each species, including the identification of gaps in such data and information. It contains information on the management and harvest regulation schemes for these coral species, with the aim of considering the effectiveness of their management and conservation. The report intends to inform the CITES parties of the status of the management and trade of precious corals, in order to provide guidance on the actions needed to enhance the conservation and sustainable use of precious corals.
Global Trade and Cultural Authentication, edited by Joanne Eicher, showcases the complexity and enduring aesthetic and ingenuity of Kalabari artisans. The Kalabari people, most of whom make their homes in the eastern Niger Delta region of western Africa, are renowned for the artistry in working with globally imported textiles and dress for centuries. The 22 essays in this edited volume feature the work of leading Nigerian and American scholars and offer an in-depth, nuanced understanding of Kalabari textiles, aesthetics, and engagement with past and present global trade networks. Using dress and textiles as a lens, Global Trade and Cultural Authentication explores the Kalabari people's centuries-long role in the global trade arena. Their economic interconnectedness demonstrates that Africa was never a "dark continent" but, rather, critically involved in a global trade built around Kalabari resourcefulness and imagination.
Law plays an essential part in the conservation of wildlife and ecosystems. The study of wildlife and nature conservation law is an important component of a wide range of programmes of study including wildlife conservation, environmental management and environmental law. This book has been produced in a convenient format so that it can be used at any time, in any place. It allows the reader to learn and revise the meaning of terms used in wildlife and nature conservation law and study the role of legislation at national, European Union (EU) and international level in the protection of individual species, habitats and landscapes. It uses examples from a wide variety of taxa, habitats and protected areas selected from a range of jurisdictions from the United Kingdom, the United States and Australia to Antarctica and the High Seas. Topics include the control of hunting, the conservation of trees and forests, the protection of National Parks and wilderness areas, wildlife trade and the organisations involved in the enforcement of wildlife laws. The structure of the book allows the study of one topic area at a time, progressing through simple questions to those that are more demanding. Some of the questions require students to use their knowledge to interpret information provided in the form of photographs and legal texts.
This circular stems from a study carried out for FAO projects “Sustainable Fisheries Management and Biodiversity Conservation of Deep-Sea Living Marine Resources and Ecosystems in the Areas Beyond National Jurisdiction” (GCP/GLO/366/GFF) and “Deep-Sea Sponge Grounds Ecosystems of the North Atlantic: An Integrated Approach Towards their Preservation and Sustainable Exploitation” (GCP/GLO/679/EC). These projects included outputs related to the economic valuation of goods and services provided by the deep seas in areas beyond national jurisdiction. This study compiled an estimate of the total economic value (TEV) of the deep seas, which considered the provision of deep-water fish, the harvest of precious corals, the use of substances of marine origin as pharmaceuticals, the extraction of deep and ultra-deep oil and the potential mining of mineral resources from the seafloor, carbon sequestration carried out by the deep seas, the importance of scientific research in the deep seas, and touristic activities with submersibles to visit sites such as the Titanic shipwreck. Comprehensively, the TEV assessed for the deep-sea ecosystem as a whole is estimated at USD 267 billion per year. Ninety two percent of the economic value originates from abiotic resources (oil and minerals), 5 percent from biotic resources (fish, corals and pharmaceuticals of marine origin), 2 percent from cultural services (scientific research and tourism/recreation), and 1 percent from carbon sequestration.

Corals comprise a wide variety of colonial marine invertebrates belonging to the Phylum Cnidaria. Their polyps form the most colorful, complete, and diverse communities on the Earth resembling underwater cities, commonly called coral reefs, which host a wide variety of invertebrates and fish species. They are highly productive ecosystems, contribute to the health of the biosphere, and offer a good number of economic and ecological services to coastal populations and to many people around the world. However, due to a diverse number of natural and anthropogenic stressors, corals have shown a severe decline over the past few decades. Being aware of the importance and relevance of the facts described, the book "Corals in a Changing World" offers new scientific information regarding the actual status and, in some cases, the resilience state of coral reef systems. Timely information is critical for managers and decision makers to implement sustainable management measures according to the ecological condition of coral reefs. In addition, the book also discusses the use of well-maintained coral microcosms to provide a good basis for performing experiments with natural fluctuations and to present studies dedicated to the coral diversity characterization and to their importance as a source of important biological compounds, which could be converted into industrial products.
Explores emerging monitoring strategies and presents adaptive management techniques to anticipate and mitigate coral bleaching, with emphasis upon identification and promotion of resilience in coral reef ecosystems. Includes coverage of strategic use of marine protected areas.
