Book Description
MARINE BIOLOGY Marine Biology: Comparative Ecology of Planet Ocean provides a learning tool to those who love the ocean to help them understand and learn about the life that populates it, the extraordinary adaptations of marine organisms to their environment, and the spectacular variety of marine life forms that inhabit the many marine habitats and contribute to the life support system of Planet Ocean. The book introduces marine biology by seeing the ocean through the eyes of its inhabitants, describing the properties of sea water, the surface waters and its currents, and the characteristics of the seabed according to how marine organisms perceive, exploit, and shape them. This book explains to the reader and those who love the ocean not only how to recognize the most common marine organisms and habitats, from the coast to great depths, but it also explains their complex life cycles and the environmental factors controlling their distribution, reproduction, and growth. Finally, the book evaluates the role that living biota play in how different marine ecosystems function in order to understand better their characteristics, peculiarities, and threats. This book offers an up-to-date and comprehensive text on the study of marine biology, presenting insights into the methodologies scientists have adopted for the study of marine ecosystems. It also includes chapters about human impacts on marine biodiversity, from overfishing to climate change, from pollution (including microplastics), to alien-species invasions, from conservation of marine resources to the restoration of degraded marine habitats. The authors developed this text for Bachelor and Master’s level students taking classes on marine biology and marine ecology, but it will also interest high-school students and marine enthusiasts (dive masters, tour guides) who wish to deepen their knowledge of marine biology.

Book Description
Between 1995 and 1997, FAO in cooperation with fisheries research institutions and administrations in selected countries in Asia, Africa, Latin America and Europe, carried out studies on the economic and financial viability of the most common fishing craft and gear combinations. Information on the level of exploitation of fisheries resources as well as government policies on fisheries management, financial services, etc., was also collected. The countries covered by the studies include Peru, Argentina, Senegal, Ghana, China, Republic of Korea, Taiwan Province of China, Indonesia, Malaysia, Thailand, India, France, Spain and Germany. Together, they accounted for about 48 per cent of the total marine capture fisheries production in South America, Europe, Africa and Asia which again accounted for 84 per cent of the global marine capture fisheries production in 1995. The findings of the studies were presented and discussed at an interregional workshop which was held in Kuala Lumpur, Malaysia, from 15 to 18 December 1997. They suggest that - in spite of fully and sometimes over-exploited fisheries resources - in most cases, marine capture fisheries is an economically and financially viable undertaking which generates sufficient revenue to cover the cost of depreciation as well as the opportunity cost of capital to generate funds for reinvestment in addition to employment, income and foreign exchange earnings.

Book Description
World Seas: An Environmental Evaluation, Second Edition, Volume Three: Ecological Issues and Environmental Impacts covers global issues relating to our seas, including a biological description of the coast and continental shelf waters, the development and use of the coast, landfills and their effects, pollutant discharges over time, the effects of over-fishing, and the management methods and techniques used to ensure continued ecosystem functioning. The relative importance of water-borne and airborne routes differ in different parts of the world is explored, along with extensive coverage of major habitats and species groups, governmental, education and legal issues, fisheries effects, remote sensing, climate change and management. This book is an invaluable, worldwide reference source for students and researchers concerned with marine environmental science, fisheries, oceanography and engineering and coastal zone development. - Provides scientific reviews of regional issues, empowering managers and policymakers to make progress in under-resourced countries and regions - Covers environmental issues arising from the human use of both the sea and its watershed - Presents informed commentary on major trends, problems and successes, and recommendations for the future
