Available in PDF, EPUB and Kindle. Book excerpt: Interest in marine mammals has increased dramatically in the last few decades, as evidenced by the number of books, scientific papers, and conferences devoted to these animals. Nowadays, a conference on marine mammals can attract between one and two thousand scientists from around the world. This upsurge of interest has resulted in a body of knowledge which, in many cases, has identified major conservation problems facing particular species. At the same time, this knowledge and the associated activities of environmental organisations have served to introduce marine mammals to a receptive public, to the extent that they are now perceived by many as the living icons of biodiversity conservation. Much of the impetus for the current interest in marine mammal conservation comes from "Save the Whale" campaigns started in the 1960s by environmental groups around the world, in response to declining whale populations after over-exploitation by humans. This public pressure led to an international moratorium on whaling recommended in 1972 by the United Nations Conference on the Human Environment in Stockholm, Sweden, and eventually adopted by the International Whaling Commission ten years later. This moratorium largely holds sway to this day, and further protective measures have included the delimitation of extensive areas of the Indian Ocean (1979) and Southern Ocean (1994) as whale sanctuaries.
Download or read book Ethology and Behavioral Ecology of Odontocetes written by Bernd Würsig and published by Springer. This book was released on 2019-08-02 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book concentrates on the marine mammalian group of Odontocetes, the toothed whales, dolphins, and porpoises. In 23 chapters, a total of 40 authors describe general patterns of ethological concepts of odontocetes in their natural environments, with a strong bent towards behavioral ecology. Examples are given of particularly well-studied species and species groups for which enough data exist, especially from the past 15 years. The aim is to give a modern flavor of present knowledge of ethology and behavior of generally large-brained behaviorally flexible mammals that have evolved quite separately from social mammals on land. As well, the plight of populations and species due to humans is described in multiple chapters, with the goal that an understanding of behavior can help to solve or alleviate at least some human-made problems.
Download or read book Puget Sound Whales for Sale written by Sandra Pollard and published by Arcadia Publishing. This book was released on 2014-06-24 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: A look at the history of the commercial capturing of orcas in Washington’s Puget Sound, the whales taken, and the efforts to save them. In November, 2005, Washington’s iconic killer whales, known as Southern Resident orcas, were placed on the endangered species list. It was a victory long overdue for a fragile population of fewer than one hundred whales. Author and certified marine naturalist Sandra Pollard traces the story and destinies of the many Southern Resident orcas captured for commercial purposes in or near the Puget Sound between 1964 and 1976. During this time, these highly intelligent members of the dolphin family lost nearly one-third of their population. Drawing on original archive material, this important volume outlines the history of orca captivity while also recounting the harrowing struggle—and ultimate triumph—for the Puget Sound orcas’ freedom. “Making liberal use of interviews, correspondence and newspaper accounts, as well as less intensive use of legislative, governmental, and nonprofit records, Pollard constructs an easily digestible narrative for lay individuals curious about the hunting of Puget Sound’s Northern and Southern Resident killer whale groups between 1965 and 1976. Puget Sound Whales for Sale significantly succeeds the former (Blackfish) in breadth and depth.” —Pacific Northwest Quarterly

Download or read book Of Orcas and Men written by David Neiwert and published by Abrams. This book was released on 2015-06-16 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: A journalist “convincingly spells out the threats to their survival, their misery in captivity, and what scientists can learn by studying them” (Kirkus). The orca—otherwise known as the killer whale—is one of earth’s most intelligent animals. Remarkably sophisticated, orcas have languages and cultures and even long-term memories, and their capacity for echolocation is nothing short of a sixth sense. They are also benign and gentle, which makes the story of the captive-orca industry—and the endangerment of their population in Puget Sound—that much more damning. In Of Orcas and Men, a marvelously compelling mix of cultural history, environmental reporting, and scientific research, David Neiwert explores an extraordinary species and its occasionally fraught relationship with human beings. Beginning with their role in myth and contemporary culture, Neiwert shows how killer whales came to capture our imaginations, and brings to life the often catastrophic environmental consequences of that appeal. In the tradition of Barry Lopez’s classic Of Wolves and Men, David Neiwert’s book is a triumph of reporting, observation, and research, and a powerful tribute to one of the animal kingdom’s most remarkable members. Praise for Of Orcas and Men “Human beings need to learn from and understand the cooperative nature of orca society. Everyone who is interested in both animal and human behavior should read this remarkable book.” —Temple Grandin, New York Times–bestselling author of Animals in Translation and Animals Make Us Human “Powerful and beautifully written.” —Jane Goodall “Humans and killer whales have a long and complicated history, one that David Neiwert describes forcefully and eloquently in this fascinating and highly readable book.” —David Kirby, New York Times–bestselling author of Death at SeaWorld “[A] breathtaking survey of orca science, folklore, and mystery.” —The Stranger

Download or read book Exploring the Mechanisms and Functions Underpinning the Social Networks of an Endangered Population of Killer Whales Orcinus Orca written by Emma Anne Foster and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: For the majority of social species, group composition is dynamic, and individuals are interconnected in a heterogeneous social network. In this study I investigate the mechanisms underpinning social structure in the endangered southern resident killer whale (Orcinus Orca) population using a long term dataset, and explore the consequences of these. My results demonstrate that resource availability may be an important determinant of social network structure. A significant relationship between the connectivity of the social network and salmon abundance occurred, with a more interconnected network in years of high salmon abundance. As networks are non-random, highly connected individuals may play a key role in population processes such as information and disease transmission. While associations occurred both within and between matrilines, females had a significantly higher number of associates than males, as did older individuals of both sexes. Older males played a more important role in interconnecting the network. The attributes of group leadership were then investigated in matrilines and in individuals. Leadership was not a factor of size or mean age of matriline. However, there was a significant relationship between leadership score and the matriline sex ratio. Individually, females had higher leadership scores than males, and there was a positive correlation between leadership score and age in both sexes. I suggest that the oldest females have the highest 4 leadership scores due to increased ecological knowledge that comes with a prolonged lifespan. Using multi-generational records for two populations of killer whales, I show that both reproductive and post-reproductive mothers increase the survival of offspring, particularly in older male offspring. This is consistent with theoretical predictions, and may explain why female killer-whales have evolved the longest post-reproductive lifespan of all non-human animals. Given the role that individuals of high network centrality can play in population processes, understanding the driving forces behind social network structure is vital when designing effective conservation and management plans.
Download or read book Puget Sound Orca in Captivity A The Fight To Bring Lolita Home written by Sandra Pollard and published by Arcadia Publishing. This book was released on 2019 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: On August 8, 1970, the Southern Resident orcas of Puget Sound were herded into Penn Cove on Whidbey Island by explosives, spotter planes and speedboats in a coordinated effort to capture seven young whales. Between 1964 and 1976, dozens of these now-endangered orcas were torn from their home and sent to marine parks around the globe. Just over a decade later, all but one had died. This lone survivor is Tokitae, also known as Lolita, and she's spent most of her life performing at the Miami Seaquarium. For twenty years, the Orca Network has called for her release, and now the indigenous Lummi Nation, People of the Sea, have joined the fight. Author Sandra Pollard chronicles the extraordinary effort to bring Tokitae home.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Transients written by John K.B. Ford and published by UBC Press. This book was released on 2011-11-01 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on transient killer whales. Enigmatic and elusive, these mammal-hunting whales are difficult animals to study. They travel in small groups, often moving unpredictably, which makes them less conspicuous than the larger resident pods. For these and other reasons, our understanding of the life history and ecology of transient killer whales has lagged behind that of residents. Transients contains the latest information on the natural history of transient killer whales, including their feeding habits, social lives, and distribution patterns. The catalogue section contains photographs of and notes on over 200 individual whales. Numerous sidebars contain interesting observations on encounters with transients as well as information on how and where to best watch them.
