Book Description
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.

Book Description
“This bracing history charts the myths, the exploration, and the inhabitants of the all-too-real and wild circumpolar ocean to our south.” —The Sydney Morning Herald, Pick of the Week Unlike the Pacific, Atlantic, Indian, and Arctic Oceans with their long maritime histories, little is known about the Southern Ocean. This book takes readers beyond the familiar heroic narratives of polar exploration to explore the nature of this stormy circumpolar ocean and its place in Western and Indigenous histories. Drawing from a vast archive of charts and maps, sea captains’ journals, whalers’ log books, missionaries’ correspondence, voyagers’ letters, scientific reports, stories, myths, and her own experiences, Joy McCann embarks on a voyage of discovery across its surfaces and into its depths, revealing its distinctive physical and biological processes as well as the people, species, events, and ideas that have shaped our perceptions of it. The result is both a global story of changing scientific knowledge about oceans and their vulnerability to human actions and a local one, showing how the Southern Ocean has defined and sustained southern environments and people over time. Beautifully and powerfully written, Wild Sea will raise a broader awareness and appreciation of the natural and cultural history of this little-known ocean and its emerging importance as a barometer of planetary climate change. “A sensitive portrait of a complex ecosystem, from krill to blue whales, and of the ice, winds, and currents that are critical to the circulation of the world’s oceans.” —Harper’s “Wilderness seekers will rejoice in this stirring portrait . . . McCann deftly navigates both natural glories and archival complexities.” —Nature

Book Description
"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"--

Book Description
Recounts mankind's dramatic history from Magellan through the first years of the twenty-first century in the part of the Antarctic regions below South America and the Atlantic Ocean. This part of the world, by far the most visited portion of the south polar regions, is not only a place of staggering scenic beauty and amazing wildlife, but also a locale with a long and fascinating human history.

Book Description
A rat will go out of its way to help a stranger in need. Lions have adopted the calves of their prey. Ants farm fungus in cooperatives. Why do we continue to believe that life in the animal kingdom is ruled by competition? In The Social Lives of Animals, biologist Ashley Ward takes us on a wild tour across the globe as he searches for a more accurate picture of how animals build societies. Ward drops in on a termite mating ritual (while his guides snack on the subjects), visits freelance baboon goatherds, and swims with a mixed family of whales and dolphins. Along the way, Ward shows that the social impulses we’ve long thought separated humans from other animals might actually be our strongest connection to them. Insightful, engaging, and often hilarious, The Social Lives of Animals demonstrates that you can learn more about animals by studying how they work together than by how they compete.

Book Description
This book is the first stand-alone and definitive account of the cetaceans of the oceanic region from the equator to Antarctica, and between the longitudes of 20° W and 80° E - a region that includes almost two-thirds of the world's marine cetacean species. In the fascinating accounts of 51 species of whales and dolphins (and one porpoise), information for this region is comprehensively summarised, allowing Peter Best to give us the benefit of his extensive knowledge and of the wealth of unpublished information he has accumulated during his 40 years of studying these creatures. Approximately 100 illustrations have been created in colour for this book by world-renowned marine mammal illustrator Pieter Folkens. Colour photographs of the living animal portray the 'jizz' of each species and specific coloration or behavioural features.
