The 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.

In this book, the editors present a view of the socioecology of primates and cetaceans in a comparative perspective to elucidate the social evolution of highly intellectual mammals in terrestrial and aquatic environments. Despite obvious differences in morphology and eco-physiology, there are many cases of comparable, sometimes strikingly similar patterns of sociobehavioral complexity. A number of long-term field studies have accumulated a substantial amount of data on the life history of various taxa, foraging ecology, social and sexual relationships, demography, and various patterns of behavior: from dynamic fission–fusion to long-term stable societies; from male-bonded to bisexually bonded to matrilineal groups. Primatologists and cetologists have come together to provide four evolutionary themes: (1) social complexity and behavioral plasticity, (2) life history strategies and social evolution, (3) the interface between behavior, demography, and conservation, and (4) selected topics in comparative behavior. These comparisons of taxa that are evolutionarily distant but live in comparable complex sociocognitive environments boost our appreciation of their sophisticated mammalian societies and can advance our understanding of the ecological factors that have shaped their social evolution. This knowledge also facilitates a better understanding of the day-to-day challenges these animals face in the human-dominated world and may improve the capacity and effectiveness of our conservation efforts.

Stewarding the Sound uses different perspectives to build awareness of the wealth and fragility of this ecosystem by balancing economic and social needs with conservation. This book, the first ever compilation of the ecological importance of the Sound, demonstrates the cumulative stresses that are now occurring within the Sound and the impact that these stresses are having on the ecosystem. This contributed volume will provide the means of reaching a wide audience to spread awareness of how ecologically important this region is and that it requires a sound management plan so that its ecosystem and the services that ecosystem provides are not compromised.

The Dusky Dolphin: Master Acrobat Off Different Shores covers various topics about the dusky dolphin, including its taxonomy, history and demography, ecology, and behavior. After introducing the dusky dolphin as a member of the genus Lagenorhynchus under the family Delphinidae, the book continues by describing its life history, its demographic patterns, and its role in the food web considering predation, parasitism, and competition. The book also includes chapters that discuss the interaction of the dusky dolphin with its habitats, such as the dusky dolphin's sound production, its foraging at night and in daylight, its survival strategies in response to predator threats, the mating habits of New Zealand duskies, calf rearing, sexual segregation, and genetic relationships. Other chapters address the interaction of dusky dolphins with humans. This book offers information about dusky dolphins off Southern Africa and discussions about the patterns of sympatry in Lagenorhynchus and Cephalorhynchus. Finally, comparisons between dusky dolphins and great apes as large-brained mammals are also reviewed in this book. - Only book fully devoted to the southern hemisphere "dusky" dolphin - Heavily illustrated with charts, figures, tables, and all color photos - Written by a cadre of experts intimately familiar with dolphin field work - Written in an accurate yet accessible style for the scientist and natural historian alike

In Listening to Whales, Alexandra Morton shares spellbinding stories about her career in whale and dolphin research and what she has learned from and about these magnificent mammals. In the late 1970s, while working at Marineland in California, Alexandra pioneered the recording of orca sounds by dropping a hydrophone into the tank of two killer whales. She recorded the varied language of mating, childbirth, and even grief after the birth of a stillborn calf. At the same time she made the startling observation that the whales were inventing wonderful synchronized movements, a behavior that was soon recognized as a defining characteristic of orca society. In 1984, Alexandra moved to a remote bay in British Columbia to continue her research with wild orcas. Her recordings of the whales have led her to a deeper understanding of the mystery of whale echolocation, the vocal communication that enables the mammals to find their way in the dark sea. A fascinating study of the profound communion between humans and whales, this book will open your eyes anew to the wonders of the natural world.
