Based on actual data of Soviet whaling, and reliable methodologies that existed at the time when this monograph was written, it examines the distribution and migration patterns of whales of the Southern Ocean. It defines distinct populations on the basis of phenes, as well as whale breeding zones, which are located in the adjacent to the Southern Ocean waters at lower latitudes. The book records the presence of a new species of killer whale in the Southern Ocean - Orcinus nana. Prenatal growth patterns, pregnancy and lactation duration, mean sizes of new-born whales are determined. Methods for the graphic recording of registering structures are described, and an original method for their decoding is proposed to determine animal age. The age of sexual and physical maturity, life expectancy is determined. Earlier unknown “pair formations” on the lower jaw of baleen whales and sperm whales are described, together with their macro, histological and electronic microscopic structure. The impact of the extermination of whales on the Southern Ocean ecosystem is examined, recommendations for control of the current state of whale populations are given, and perspectives of whale population recovery are estimated. Regions that could be used as testing areas for whale registration method are defined. The book is intended for biologist-cytologists, ecologists and other specialists interested in cetaceans, and for biology students.

Whales and dolphins are icons for the conservation movement. They are the most conspicuous ambassadors for entire marine ecosystems and possibly even for the biosphere as a whole. Concurrent with our realisation of impending threats to their environment is a growing scientific understanding of the social and cognitive complexity of many of these species. This book brings together experts in the relevant diverse fields of cetacean research, to provide authoritative descriptions of our current knowledge of the complex behaviour and social organization of whales and dolphins. The authors consider this new information in the context of how different human cultures from around the world view cetaceans and their protection, including attitudes to whaling. They show how new information on issues such as cetacean intelligence, culture and the ability to suffer, warrants a significant shift in global perceptions of this group of animals and how these changes might be facilitated to improve conservation and welfare approaches.

[A] fascinating volume, which establishes marine environmental history as a major new discipline for academics as well as an exciting way to bring history and the natural world alive for the public. ANDREW A. ROSENBERG, UNIVERSITY OF NEW HAMPSHIRE The HMAP project is to be congratulated on this book, which presents vivid, evidence-based reconstructions of historical fisheries and the prolific ecosystems in which they were embedded. TONY J. PITCHER, UNIVERSITY OF BRITISH COLUMBIA The ingenuity and scholarship of the authors allow us to see ... how human societies have depended on and influenced marine living resources from periwinkles to whales. MIKE SINCLAIR, BEDFORD INSTITUTE OF OCEANOGRAPHY This book exalts the surprisingly fruitful marriage of historians and marine scientists - a union that has proven to be one of the most exciting developments in ocean research in recent years. KATHERINE RICHARDSON, UNIVERSITY OF COPENHAGEN For centuries the seas appeared to offer limitless supplies of food and other resources, their waters a cornucopia never to be exhausted. In more recent times, episodes such as the extreme exploitation and subsequent collapse of cod populations of the Grand Banks off Newfoundland have highlighted the fallaciousness of this view. Yet all too often the lessons from our historical interactions with marine animals are little known, let alone learned. Based on research for the History of Marine Animal Populations project, Oceans Past examines the complex relationship our forebears had with the sea and the animals that inhabit it. It presents eleven studies ranging from fisheries and invasive species to offshore technology and the study of marine environmental history, bringing together the perspectives of historians and marine scientists to enhance understanding of ocean management of the past, present and future. In doing so, it also highlights the influence that changes in marine ecosystems have upon the politics, welfare and culture of human societies.

This book explores the lives of the world's largest living mammals. Drawing on the latest scientific research, Whales describes these incredible animals' evolution from terrestrial to marine mammals, their life cycle, diversity and distribution, and the ecosystems of which they are a part. Whales highlights the many extraordinary aspects of these intelligent and social creatures, including the complex vocalizations they use to communicate over vast distances. Philip Hammond, Sonja Heinrich, Sascha Hooker, and Peter Tyack investigate the role of whales in human culture, from whaling to whale watching, and emphasize how scientists monitor the current threats to whales and the methods they use to conserve their future. Spectacular photographs of whales in the wild reveal the private lives of these fascinating and majestic ocean giants.

International Marine Mammal Law is a comprehensive, introductory volume on the legal regimes governing the conservation and utilisation of marine mammals. Written as a textbook, it provides basic overviews of international conservation law, which enable the reader to understand the greater implications of governance of a specific group of species. Paired with biological information on some marine mammal species, the international regimes for whales, seals and polar bears are explored — either as part of global regimes of international environmental governance or as regimes that were specifically designed for them. The book concludes with outlooks on the future of international marine mammal law, particularly in light of Japan’s withdrawal from the International Convention for the Regulation of Whaling in July 2019.

Winner of the 2020 Andrew Carnegie Medal for Excellence in Nonfiction * Finalist for the 2020 Kirkus Prize for Nonfiction * Finalist for the PEN/E.O. Wilson Literary Science Writing Award A “delving, haunted, and poetic debut” (The New York Times Book Review) about the awe-inspiring lives of whales, revealing what they can teach us about ourselves, our planet, and our relationship with other species. When writer Rebecca Giggs encountered a humpback whale stranded on her local beachfront in Australia, she began to wonder how the lives of whales reflect the condition of our oceans. Fathoms: The World in the Whale is “a work of bright and careful genius” (Robert Moor, New York Times bestselling author of On Trails), one that blends natural history, philosophy, and science to explore: How do whales experience ecological change? How has whale culture been both understood and changed by human technology? What can observing whales teach us about the complexity, splendor, and fragility of life on earth? In Fathoms, we learn about whales so rare they have never been named, whale songs that sweep across hemispheres in annual waves of popularity, and whales that have modified the chemical composition of our planet’s atmosphere. We travel to Japan to board the ships that hunt whales and delve into the deepest seas to discover how plastic pollution pervades our earth’s undersea environment. With the immediacy of Rachel Carson and the lush prose of Annie Dillard, Giggs gives us a “masterly” (The New Yorker) exploration of the natural world even as she addresses what it means to write about nature at a time of environmental crisis. With depth and clarity, she outlines the challenges we face as we attempt to understand the perspectives of other living beings, and our own place on an evolving planet. Evocative and inspiring, Fathoms “immediately earns its place in the pantheon of classics of the new golden age of environmental writing” (Literary Hub).

"Marine scientist Michael J. Moore says we are all whalers, but we don't have to be. Eating fish leads to North Atlantic right whales' entanglement and death. Buying goods made around the world requires global shipping routes, which do not accurately consider right whale breeding and feeding sites, leading to collision. To explain this, Moore conveys to readers scenes from over thirty years' worth of fieldwork, performing whale necropsies for animals stranded on beaches, working as an independent researcher alongside whalers using explosive harpoons, and tracking injured pregnant whales to deliver antibiotics. Despite these sometimes disturbing experiences, Moore has written a hopeful book. He uses these stories to show we can change and to tell us how; the technology for rope-less fishing and tracking whale migrations already exist to protect both right whales and the people who depend on shipping and fishing for their livelihoods"--
