Download and read online ebook Whales of the Southern Ocean write by Yuri Mikhalev. This book was released on 2020-01-28. Whales of the Southern Ocean available in PDF, EPUB and Kindle. 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.

This book was released on 2012. Oceans Past available in PDF, EPUB and Kindle. �[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 COPENHAGENFor 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.

Download and read online ebook The Breath of a Whale write by Leigh Calvez. This book was released on 2019-02-26. The Breath of a Whale available in PDF, EPUB and Kindle. An ode to marine life and the natural world, from the New York Times–bestselling author of The Hidden Life of Owls This “intimate and spirited” essay collection “offers us the whale watch most of us can only dream of” as they reveal the elusive lives of whales in the Pacific Ocean—home to orcas, humpbacks, blue, gray, and sperm whales (Sy Montgomery, author of The Soul of an Octopus). Leigh Calvez has spent a dozen years researching, observing, and probing the lives of the giants of the deep. Here, she relates the stories of nature's most remarkable creatures, including the familial orcas in the waters of Washington State and British Columbia; the migratory humpbacks; the ancient, deep-diving blue whales, the largest animals on the planet. The lives of these whales are conveyed through the work of dedicated researchers who have spent decades tracking them along their secretive routes that extend for thousands of miles, gleaning their habits and sounds and distinguishing peculiarities. Calvez author invites the reader onto a small research catamaran maneuvering among 100-foot long blue whales off the coast of California; or to join the task of monitoring patterns of humpback whale movements at the ocean surface: tail throw, flipper slap, fluke up, or blow. To experience whales is breathtaking. To understand their lives deepens our connection with the natural world.

This book was released on 2020-07-28. Fathoms available in PDF, EPUB and Kindle. 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).
