DOWNLOAD EBOOKOcean currents, winds, and rainfall all work together to create a marine oasis around the Hawaiian Islands, providing a home for many species of dolphins and whales normally found in the deep oceans of the world. The Lives of Hawai`i’s Dolphins and Whales opens a window into the world of these mysterious creatures with stories and observations from author Robin W. Baird’s work over the last seventeen years. The book includes exceptional full-color photographs of each species, life history descriptions, conservation threats, and maps showing sighting locations and movements of tagged individuals among the islands and offshore. While the well-known resident spinner dolphins and visiting humpback whales are covered, the ten species of lesser-known open-ocean dolphins and whales that are resident to the marine slopes of the islands are highlighted as well. Among these are endangered false killer whales, deep-diving Cuvier’s and Blainville’s beaked whales, abundant spotted dolphins, coastal bottlenose dolphins, cryptic dwarf sperm whales, family units of short-finned pilot whales, and social melon-headed whales. Baird also describes thirteen species of dolphins and whales that are found in offshore waters or are seasonal or occasional visitors to Hawaiian waters, including killer whales, the iconic sperm whale, and even blue whales and North Pacific right whales. More is known about the social organization and natural history of many of these marine mammals in Hawai`i than anywhere else in the world. For all of the species discussed, Baird presents data obtained from long-term photo-identification studies, with distinctive individuals tracked through time and space; for many of them, he includes findings from studies using genetics and satellite tagging. He also provides information on predators and prey, social organization, diving, and night-time behavior, along with suggestions on how to tell some of the more difficult to identify species apart. The book closes by focusing on conservation issues, both success stories and challenges, engaging readers to consider ways to protect Hawai`i’s unique assemblage of resident dolphins and whales.

The Arabian Seas: Biodiversity, Environmental Challenges and Conservation Measures

DOWNLOAD EBOOKThe Arabian Seas Marine Region encompasses marine areas from Djibouti to Pakistan, including the northern part of Somalia, the Red Sea, the Arabian/Persian Gulf, and parts of the Arabian Sea. Human pressures on the coastal and marine environments are evident throughout the region, and have resulted in harmful environmental effects. Oil and domestic, urban and industrial pollutants in several areas of this part of the world have caused local habitat degradation, eutrophication and algal blooms. Further, coastal landfill, dredging, and sedimentation, as well as nutrient and sediment runoff from phosphate mining, agriculture and grazing, and reduction in freshwater seepage due to groundwater extraction are all contributing to the degradation of coastal environments. This book discusses aspects not covered in other books on the region, which largely focus on marine biodiversity, and examines several environmental challenges that are often ignored, but which have a significant impact on the environment. Evaluating the status quo, it also recommends conservation measures and examines the abiotic factors that play a major main role in the environmental changes. Lastly, the book addresses the biodiversity of the area, providing a general context for the conservation and management measures discussed.
Identifying and Comparing Important Areas for Marine Sustainable Use and Conservation

DOWNLOAD EBOOKThe ocean is under increasing threat from the expansion of human activities. The combined impacts of these threats as well as the potential impacts of climate change and ocean acidification have placed thousands of species at risk of extinction, and have impaired the structure, function, productivity and resilience of marine ecosystems. Currently, some parts of the world's oceans are significantly impacted, yet are without any form of effective management. Only a small proportion of the oceans are within protected area systems. Globally, measures are being taken to increase protection and sustainable management, but application is uncoordinated and not always effective. In order to support effective policy action by countries and competent international and regional organizations, it is critical to build a sound understanding of the most ecologically and biologically important ocean areas that support healthy marine ecosystems so that the necessary steps to ensure the long-term function and resilience of these systems can be taken.

DOWNLOAD EBOOKThe tropics and subtropics are home to about 75% of the global human population. Cultural, economic, and political circumstances vary enormously across this vast geography of some 170 countries and territories. The regions not only harbor the world's poorest countries but their human populations are growing disproportionally faster than in temperate zones. Some countries are developing rapidly -- Brazil, China, India, and Mexico being obvious examples, while others still remain in the poverty trap. This region contains an astonishing proportion of global biodiversity; some 90% of plant and animal species by some measures. Its contribution to human well-being is astounding. It was the birthplace for our species; and it hosts a myriad of plant and animal species which products feed us, keep us healthy, and supply us with a variety of material goods. The tropics and subtropics are also a natural laboratory where some of humanity's most important scientific discoveries have been made. Such biodiversity has enormous implications for research priorities, capacity building, and policy to address the challenges of conserving this region. Tropical Conservation: Perspectives on Local and Global Priorities drew the majority of its contributors from this growing pool of scientists and practitioners working in Latin America, Africa, and Asia. It introduces important conservation concepts and illustrates their application as the authors directly capture real world experiences in their home countries in preventing biodiversity loss and sustaining ecological health. Today, no part of the world can be viewed in isolation, and we further codify and integrate a range of approaches for addressing global threats to nature and environmental sustainability, including climate change and emerging diseases. Five sections structure the major themes.
Small Cetaceans of Japan

DOWNLOAD EBOOKThis book summarizes and analyzes the biology, ecology, exploitation and management of small cetaceans in Japan. It describes the various types of cetacean fisheries in Japan and their historical development, the life histories and ecologies of the main species involved, and the history and problems of conservation and management. The data show that in some cases the number of small cetaceans harvested exceed sustainable limits and have led to depletion of populations. The book provides a case study of what can go wrong when the needs of industry and conservation collide. The descriptions of life history and ecology are relevant to issues of conservation and management, not just for cetaceans, but for all fisheries around the world.
Marine Mammal Welfare

DOWNLOAD EBOOKMarine mammals attract human interest – sometimes this interest is benign or positive – whale watching, conservation programmes for whales, seals, otters, and efforts to clear beaches of marine debris are seen as proactive steps to support these animals. However, there are many forces operating to affect adversely the lives of whales, seals, manatees, otters and polar bears – and this book explores how the welfare of marine mammals has been affected and how they have adapted, moved, responded and sometimes suffered as a result of the changing marine and human world around them. Marine mammal welfare addresses the welfare effects of marine debris, of human traffic in the oceans, of noise, of hunting, of whale watching and tourism, and of some of the less obvious impacts on marine mammals – on their social structures, on their behaviours and migration, and also of the effects on captivity for animals kept in zoos and aquaria. There is much to think and talk about – how marine mammals respond in a world dramatically influenced by man, how are their social structures affected and how is their welfare impacted?
