Download or read book The Emergence of Whales written by J.G.M. Thewissen and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research in whale origins is now in an explosive phase, with a cascade of discoveries adding to our understanding of the evolutionary pattern and a suite of new techniques being applied to address new questions. The objective of this volume is to provide a snapshot of this explosion. The volume paints the scene with a broad brush. Taken together the chapters clearly indicate that cetacean origins is a field that is dynamic, multidisciplinary, and that the end of the explosive phase is not in sight.

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 Synopsis Development of the Cetacean Nasal Skull by : Milan Klima
Download or read book Development of the Cetacean Nasal Skull written by Milan Klima and published by Springer. This book was released on with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Morphogeny of the nasal skull was investigated in 92 embryos of 13 species of Cetacea. Compared to the original nasal capsule of land mammals, the nasal structures of Cetacea show many weighty transformations. As a result, the nostrils are translocated from the tip of the snout to the vertex of the head. Several structures of the embryonic nasal skull remain preserved even in adult cetaceans. The translocation of the nostrils to the highest point of the surfacing body is among the most perfect adaptations of cetaceans to the aquatic life habits. The morphogeny of the nasal skull suggests that all cetaceans are of common origin and form a single monophyletic order. The hitherto usual division of this order into two suborders, Mysticeti and Odontoceti, appears to be unsubstantiated. Rather, at least three closely related superfamilies should be distinguished within the order Cetacea, viz., Balaenopteroidea, Physeteroidea, and Delphinoidea. The results are in a

Book excerpt: Cetaceans are one of the most unknown groups in the animal kingdom. Their study is very difficult due to their scarcity, their flighty behavior, and their enormous displacements. In addition, some species feed in very deep waters and only emerge to breathe, or they live in hard to reach areas. However, few animals create so much wonder. What child or adult has not felt emotions when contemplating the spectacles of the killer whales, the pirouettes of the dolphins, or the immensity of the whales in the middle of the sea? Some of the authors of this book have been so moved to be surrounded by a group of fin whales that could not contain their tears. It is a difficult sensation to explain. One could try to summarize it by saying that these immense animals exhale peace. Seeing dolphins making capers around a boat or a group of fin whales suddenly emerging a few meters away is one of the greatest shows we can see in nature. In the presence of these animals, there is only a feeling of recollection. These are the moments when we see how small we humans are in this wonderful biosphere. Therefore, this book is a small tribute to these beautiful living beings. Something we owe them. We have to protect these animals, but we cannot do so without knowing them. In this text, the authors provide key information to understand the evolution of cetaceans, their patterns of movement and behavior, always under a conservation perspective.This book has been written by 15 leading specialists from three different countries and with different backgrounds ranging from biology to veterinary science. They are united by a common interest, a passion. The book does not focus on a single species, but covers studies with dolphins, sperm whales, and fin whales, as well as various methodological approaches that provide key data to understand the evolution of up to 50 different species. Many diverse aspects have been covered and, above all, new methodological approaches have been provided in areas such as acoustics, the study of spatial and feeding behavior, evolution, social interactions, and even blue economics. As if this were not enough, the authors wish to highlight the immense amount of data that has been used. The first chapter on fin whales is based on hundreds of sightings over several years, and dozens of satellite images on various environmental parameters. Chapter two covers hundreds of recordings of the sounds of humpback whales around the world. Chapter three has followed the sperm whale populations of the Strait of Gibraltar over several years with hundreds of sightings. Chapters four and five study the evolution of more than fifty species through hundreds of recordings using qualitative and quantitative approaches, respectively. The sixth chapter compares the behavior of two species of dolphins. Finally, chapter seven designs a new line of study for these animals: the blue economy.
Book Synopsis Embryology of Dolphins by : Oldrich Sterba
Download or read book Embryology of Dolphins written by Oldrich Sterba and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rapid development of molecular biology and genetics has led to renewed interest in embryology, comparative embryology, and studies of the relations between ontogeny and phylogeny. In fact, genes have been identified which are involved in the formation of shapes and structures, and it is becoming apparent that their primary morphological expressions are conspicuously similar in different species. The primarily identical shapes do not become diversified until advanced individualization of embryos, and it is here that it is possible to employ the knowledge of comparative embryology, the branch of science engaged in the study of the development and differentiation of tridimensional structures in different animal groups. However, comparative embryology has been neglected during the past decades, as its development has appeared to have been completed. In our opinion, the decreased interest in comparative embryology has been caused by the fact that often the time factor was not or could not be respected. In fact, in the case of embryos of wild animals even their ontogenetic age and sometimes the duration of intrauterine development are unknown.
