Download or read book Cetacean Paleobiology written by Felix G. Marx and published by John Wiley & Sons. This book was released on 2016-03-29 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cetaceans (whales, dolphins, and porpoises) have fascinated and bewildered humans throughout history. Their mammalian affinities have been long recognized, but exactly which group of terrestrial mammals they descend from has, until recently, remained in the dark. Recent decades have produced a flurry of new fossil cetaceans, extending their fossil history to over 50 million years ago. Along with new insights from genetics and developmental studies, these discoveries have helped to clarify the place of cetaceans among mammals, and enriched our understanding of their unique adaptations for feeding, locomotion and sensory systems. Their continuously improving fossil record and successive transformation into highly specialized marine mammals have made cetaceans a textbook case of evolution - as iconic in its own way as the origin of birds from dinosaurs. This book aims to summarize our current understanding of cetacean evolution for the serious student and interested amateur using photographs, drawings, charts and illustrations.

Book excerpt: “A palaeontological howdunnit…[Spying on Whales] captures the excitement of…seeking answers to deep questions in cetacean science.” —Nature Called “the best of science writing” (Edward O. Wilson) and named a best book by Popular Science, a dive into the secret lives of whales, from their four-legged past to their perilous present. Whales are among the largest, most intelligent, deepest diving species to have ever lived on our planet. They evolved from land-roaming, dog-sized creatures into animals that move like fish, breathe like us, can grow to 300,000 pounds, live 200 years and travel entire ocean basins. Whales fill us with terror, awe, and affection--yet there is still so much we don't know about them. Why did it take whales over 50 million years to evolve to such big sizes, and how do they eat enough to stay that big? How did their ancestors return from land to the sea--and what can their lives tell us about evolution as a whole? Importantly, in the sweepstakes of human-driven habitat and climate change, will whales survive? Nick Pyenson's research has given us the answers to some of our biggest questions about whales. He takes us deep inside the Smithsonian's unparalleled fossil collections, to frigid Antarctic waters, and to the arid desert in Chile, where scientists race against time to document the largest fossil whale site ever found. Full of rich storytelling and scientific discovery, Spying on Whales spans the ancient past to an uncertain future--all to better understand the most enigmatic creatures on Earth.

Download or read book The Therian Skull written by James G. Mead and published by . This book was released on 2009 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cetaceans form one of the most unique groups in the evolutionary history of mammals. They have returned to the sea and modified their tail as an efficient means of locomotion. As they adapted to the limited visibility in the aquatic environment, the odontocetes developed a system of echolocation that resulted in extensive modifications to the skull bones. This made descriptive comparisons very difficult and early anatomists unwittingly composed new terms for anatomical structures that had already been named in other taxa. This made anatomical comparisons, based on the literature, extremely tenuous. This lexicon is an attempt to remedy that situation in that it provides headwords and definitions for all the terms that have been used in describing the mammal skull and notes the synonymous terms. The lexicon includes the human nomenclature (Nomina Anatomica), the veterinary nomenclature (Nomina Anatomica Veterinaria) and the nomenclature that is used in descriptive comparative anatomy. The lexicon covers not only extant but extinct mammalian groups and is extensively indexed.
Download or read book Mammalogy written by Terry Vaughan and published by Jones & Bartlett Learning. This book was released on 2011-04-21 with total page 770 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Newly revised and extensively updated, the fifth edition of Mammalogy explains and clarifies the subject of mammalian biology as a unified whole, taking care to discuss the latest and most fascinating discoveries in the field. In recent years we witnessed significant changes in the taxonomy of mammals. The authors kept pace with such changes and revised each chapter to reflect the most current data and statistics available. New pedagogical elements, including chapter outlines, lists of key morphological characteristics, and further reading sections, help readers grasp the most important concepts and explore additional content on their own." --Book Jacket.

Download or read book A Manual of the Mammalia written by Douglas A. Kelt and published by University of Chicago Press. This book was released on 2020-10-02 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: The taxonomy of recent mammals has lately undergone tremendous revision, but it has been decades since the last update to Timothy E. Lawlor’s acclaimed identification guide the Handbook to the Orders and Families of Living Mammals. Integrating the latest advances in research, Douglas A. Kelt and James L. Patton provide this long-overdue update in their new, wholly original work, A Manual of the Mammalia. Complemented by global range maps, high-resolution photographs of skulls and mandibles by Bill Stone, and the outstanding artwork of Fiona Reid, this book provides an overview of biological attributes of each higher taxon while highlighting key and diagnostic characters needed to identify skulls and skins of all recent mammalian orders and most families. Kelt and Patton also place taxa in their currently understood supra-familial clades, and discuss current challenges in higher mammal taxonomy. Including a comprehensive review of mammalian anatomy to provide a foundation for understanding all characters employed throughout, A Manual of the Mammalia is both a user-friendly handbook for students learning to identify higher mammal taxa and a uniquely comprehensive, up-to-date reference for mammalogists and mammal-lovers from across the globe.

Download or read book Echolocation in Bats and Dolphins written by Jeanette A. Thomas and published by University of Chicago Press. This book was released on 2004 with total page 636 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although bats and dolphins live in very different environments, are vastly different in size, and hunt different kinds of prey, both groups have evolved similar sonar systems, known as echolocation, to locate food and navigate the skies and seas. While much research has been conducted over the past thirty years on echolocation in bats and dolphins, this volume is the first to compare what is known about echolocation in each group, to point out what information is missing, and to identify future areas of research. Echolocation in Bats and Dolphins consists of six sections: mechanisms of echolocation signal production; the anatomy and physiology of signal reception and interpretation; performance and cognition; ecological and evolutionary aspects of echolocation mammals; theoretical and methodological topics; and possible echolocation capabilities in other mammals, including shrews, seals, and baleen whales. Animal behaviorists, ecologists, physiologists, and both scientists and engineers who work in the field of bioacoustics will benefit from this book.
Download or read book Sensory Abilities of Cetaceans written by Jeanette A. Thomas and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 702 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book evolved through the efforts of several organizations and the dedication of many individuals. In 1987, we received arequest to propose a workshop topic for the Fifth International Theriological Congress (ITC) to be held in August 1989 in Rome, Italy. After looking up the meaning of the word "theriological" in the dictionary and discovering that it pertains to mammalian behavior, we decided a symposium on sensory abilities of whales and dOlphins would be an interesting topic. The ITC convenes only every five years and has the distinction of being very weIl attended by scientists from around the world. We thought that hosting a workshop in conjunction with the ITC would attract a variety of international scientists that rarely have the opportunity to interact. Fortunately for all involved, our prediction was correct. The first two days of the workshop, 23-24 August 1989, were held in conjunction with ITC and the nearly 1,000 attending scientists were able to view our posters and listen to lectures. The third day was limited to only ab out 65 invited scientists who were divided into topical working groups chaired by a rapporteur.
