Download or read book Wild Blue written by Dan Bortolotti and published by Macmillan. This book was released on 2008-10-14 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: The blue whale holds the title of largest creature that has ever lived, and it may also be the most mysterious. The biggest blue whales can outweigh every player in Major League Baseball and the National Hockey League combined. Their mouths can gulp more than thirteen thousand gallons of seawater. A newborn can be over twenty feet long and gain nearly twenty tons in seven months—about eight pounds per hour. Blue whales emit more powerful sounds than any other animal on earth, though many of their vocalizations are beyond the range of human hearing. Yet nearly everything that we have learned about blue whales has come after humans almost wiped them out from the oceans. A century ago, some three hundred thousand roamed the seas. But in the first decades of the twentieth century, humans hunted and killed 99.9% of them. Their numbers decimated, the species seemed destined for extinction. Only in recent years has the number slowly begun to increase, along with hope for the blue whale's future. Equal parts history and science, Wild Blue is the first comprehensive portrait of the blue whale. It draws upon new findings from scientists who have begun to identify individual blue whales and understand how they dive, how they feed, where they migrate, and why they emit their haunting, low-frequency calls. With deft, poignant writing, Dan Bortolotti gives us the most vibrant, breathtaking view to date of these magnificent creatures.

Available in PDF, EPUB and Kindle. Book excerpt: 'Erich Hoyt's handbook is an admirable, timely and highly welcome contribution.'Michael Stachowitsch, Marine EcologyWhat does it mean to save the whales if their habitat is left unprotected? Marine Protected Areas for Whales, Dolphins and Porpoises is the definitive handbook on this pressing issue and the first to bridge the gap between the disciplines of marine protected areas and cetacean conservation. It launches a new chapter in cetacean conservation with its investigation into the crucial habitat needs and protection requirements of some 84 species.The author, one of the world's foremost experts in this field, takes you around the world to investigate the promising results of the latest conservation research and the strategies for obtaining marine protected areas in coastal waters and on the high seas, using national legislation and regional and international conventions. This is an essential introduction, guide and reference work for those working to ensure a future for whales and dolphins.

Book Synopsis A Little Less Arctic by : Steven H. Ferguson
Download or read book A Little Less Arctic written by Steven H. Ferguson and published by Springer Science & Business Media. This book was released on 2010-05-30 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Arctic Canada, Hudson Bay is a site of great exploration history, aboriginal culture, and a vast marine wilderness supporting large populations of marine mammals and birds. These include some of the most iconic Arctic animals like beluga, narwhal, bowhead whales, and polar bears. Due to the challenges of conducting field research in this region, some of the mysteries of where these animals move, and how they are able to survive in such seemingly inhospitable, ice-choked habitats are just now being unlocked. For example, are polar bears being replaced by killer whales? This new information could not be more salient, as the Hudson Bay Region is undergoing rapid environmental change due to global warming, as well as increased pressures from industrial development interests. A Little Less Arctic brings together some of the world’s leading Arctic scientists to present the current state of knowledge on the physical and biological characteristics of Hudson Bay.

Book Synopsis Effective Ecological Monitoring by : Gene Likens
Download or read book Effective Ecological Monitoring written by Gene Likens and published by CSIRO PUBLISHING. This book was released on 2018-05-01 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: Long-term monitoring programs are fundamental to understanding the natural environment and managing major environmental problems. Yet they are often done very poorly and ineffectively. This second edition of the highly acclaimed Effective Ecological Monitoring describes what makes monitoring programs successful and how to ensure that long-term monitoring studies persist. The book has been fully revised and updated but remains concise, illustrating key aspects of effective monitoring with case studies and examples. It includes new sections comparing surveillance-based and question-based monitoring, analysing environmental observation networks, and provides examples of adaptive monitoring. Based on the authors’ 80 years of collective experience in running long-term research and monitoring programs, Effective Ecological Monitoring is a valuable resource for the natural resource management, ecological and environmental science and policy communities.
Book Synopsis Recording Structures of Mammals by : Galina A. Klevezal
Download or read book Recording Structures of Mammals written by Galina A. Klevezal and published by CRC Press. This book was released on 1995-06-01 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text focuses on the principles and methods of using growth layers formed in teeth and bones of mammals to make a judgement on essential traits of the animal's life history. In nearly all mammalian species, including man, the age of individuals can be determined from the number of growth layers and, at least in some of them, it is possible to estimate the season of an animal's birth and death, age of sexual maturation, periodicity of reproduction, certain feeding habits and other aspects of the individual's biology. It is also possible, from tooth-enamel analysis, to assess doses of radiation accumulated by animals and human beings during their lifetime.;This book is intended for zoologists, wild-game biologists and zoo archaeologists, but some of the sections could also be of interest for anthropologists, radioecologists and conservation biologists.
