Available in PDF, EPUB and Kindle. Book excerpt: Twenty years in the making by a distinguished dolphin expert and his associates, The Hawaiian Spinner Dolphin is the first comprehensive scientific natural history of a dolphin species ever written. From their research camp at Kealakeakua Bay in Hawaii, these scientists followed a population of wild spinner dolphins by radiotracking their movements and, with the use of a windowed underwater vessel, observing the details of their underwater social life. The authors begin with a description of the spinner dolphin species, its morphology and systematics, and then examine the ocean environment, the organization of dolphin populations, and the way this school-based society of mammals uses shorelines for rest and instruction of the young. The dolphins' reproductive cycle, their vision, vocalization, hearing, breathing, and feeding, and the integration of the school are carefully analyzed. The authors conclude with a comprehensive evolutionary analysis of this marine cultural system, with its behavioral flexibility and high levels of cooperation. This absorbing book is the richest source available of new scientific insights about the lives of wild dophins and how their societies evolved at sea.

Available in PDF, EPUB and Kindle. Book excerpt: Marine environments are known for their dynamic, unpredictable nature. Therefore, search behaviour is particularly important for marine animals. Despite this, movement patterns and search behaviour of marine animals, and particularly fish, are poorly known. Here I investigate some unanswered questions relating to the search behaviour of a predatory marine fish, the small-spotted catshark (Scyliorhinus canicula). This research uses a combination of field-based tracking and laboratory investigations to evaluate the development of search behaviour. In the wild both male and female adults exhibited movements resembling central place foraging. These movements were characterised by preferential use of core areas from which discrete excursions were made at particular times prior to return to the core area. Despite this, sex differences in movements were found. Females undertook relatively infrequent, mainly nocturnal, long range excursions whereas males made more frequent excursions of variable duration and extent throughout both the day and night. In the laboratory, movement patterns of juveniles were consistent with a simple random walk model of movement, regardless of prey distribution or density. The resulting foraging efficiencies were also similar irrespective of treatment. The movements of males in the wild also appeared to be consistent with a random walk model, although a truncated-power law was found to be a good fit to some of the step length data, with exponent values indicative of optimal L?vy-like behaviour. Behaviour switching between different movement patterns in relation to complex changes in prey availability and distribution appears likely. In contrast, the movements of adult females in the field showed some degree of determinism, resulting in poor agreement with random walk models. The results of learning experiments with juveniles in the laboratory suggest that small-spotted catsharks may be capable of developing spatial memory, and such learning may be important for the development of efficient search tactics. Given these findings, the importance of learning with regards to search behaviour in catsharks warrants further investigation.

Available in PDF, EPUB and Kindle. Book excerpt: "Part review, part testament to extraordinary dedication, and part call to get involved, Cetacean Societies highlights the achievements of behavioral ecologists inspired by the challenges of cetaceans and committed to the exploration of a new world."—from the preface by Richard Wrangham Long-lived, slow to reproduce, and often hidden beneath the water's surface, whales and dolphins (cetaceans) have remained elusive subjects for scientific study even though they have fascinated humans for centuries. Until recently, much of what we knew about cetaceans came from commercial sources such as whalers and trainers for dolphin acts. Innovative research methods and persistent efforts, however, have begun to penetrate the depths to reveal tantalizing glimpses of the lives of these mammals in their natural habitats. Cetacean Societies presents the first comprehensive synthesis and review of these new studies. Groups of chapters focus on the history of cetacean behavioral research and methodology; state-of-the-art reviews of information on four of the most-studied species: bottlenose dolphins, killer whales, sperm whales, and humpback whales; and summaries of major topics, including group living, male and female reproductive strategies, communication, and conservation drawn from comparative research on a wide range of species. Written by some of the world's leading cetacean scientists, this landmark volume will benefit not just students of cetology but also researchers in other areas of behavioral and conservation ecology as well as anyone with a serious interest in the world of whales and dolphins. Contributors are Robin Baird, Phillip Clapham, Jenny Christal, Richard Connor, Janet Mann, Andrew Read, Randall Reeves, Amy Samuels, Peter Tyack, Linda Weilgart, Hal Whitehead, Randall S. Wells, and Richard Wrangham.

Book excerpt: This book provides an introduction to ocean sciences that is engaging, evocative and accessible to non-experts interested in marine geoscience, while sparking readers' interest in important unsolved mysteries in marine science. The scope of the book is quite broad, but focuses on the physical ocean and its geological evolution, including the author's experiences working as an oceanographer over the last thirty years. Across ten chapters, the book traces the origins of the ocean from its formation 4 billion years ago, reviews the discoveries of the theory of plate tectonics, the ice ages and the great ocean conveyor, and discusses seafloor features (canyons, seamounts, trenches, abyssal plains, etc.), how they formed and their current environmental issues. The book concludes with a prognosis for the future ocean we might expect with global climate change and other human impacts.

This book was released on 2009-06-10 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 2nd international tagging and tracking symposium was held in San Sebastian, Spain, in October 2007, seven years after the first symposium was held in Hawaii in 2000 (Sibert and Nielsen 2001). In the intervening seven years, there have been major advances in both the capability and reliability of electronic tags and analytical approaches for geolocation of tagged animals in marine habitats. Advances such as increased data storage capacity, sensor development, and tag miniaturization have allowed researchers to track a much wider array of marine animals, not just large and charismatic species. Importantly, data returned by these tags are now being used in population analyses and movement simulations that can be directly utilized in stock assessments and other management applications. Papers in this volume are divided into three sections, the first describing insights into behavior achieved using acoustic, archival, and novel tags, the second reporting on advances in methods of geolocation, while the final section includes contributions where tag data have been used in management of marine species. Accurate documentation of animal movements and behaviors in critical marine habitats are impossible to obtain with other technologies. The management and conservation of marine species are critical in today’s changing ocean environment and as electronic tags become more accurate and functional for a diversity of organisms their application continues to grow, setting new standards in science and technology.
