Available in PDF, EPUB and Kindle. Book excerpt: "Of all the literature I use while preparing field guides for the Food and Agriculture Organization of the United Nations, Nelson's Fishes of the World is, by far, the one I refer to most often. [This] book is a standard reference . . . I continue to use it extensively in the ichthyology courses I teach, particularly in laboratory sessions." -Kent E. Carpenter Old Dominion University "Fishes of the World is a unique and essential resource for anyone seriously interested in the diversity and evolution of fishes. The family accounts provide quick summaries of current knowledge on all groups of living fishes and many key fossil taxa. It is a required work for every student in my laboratory." -William E. Bemis Kingsbury Director of Shoals Marine Laboratory, Cornell University "Only classics are known by the single name of their author, and certainly [Nelson's book] has for four editions been such a book for all those who seek an accessible, up-to-date, readable reference on fish classification. Once again, Nelson presents a balanced view of the sometimes tumultuous, but ever-exciting, study of the phylogenetic relationships and classification of fishes. In doing so, Nelson makes an excellent case for organismal biology, highlighting the many and varied morphological characters we use to diagnose fish taxa and differentiate among the 515 families of living species." -Lynne R. Parenti Curator of Fishes and Research Scientist, National Museum of Natural History, Smithsonian Institution Fishes of the World, Fourth Edition is the updated edition of a true classic in the field. A unique presentation of a modern, cladistically based classification of all the major living and fossil fish groups, this indispensable reference helps scientists and others identify and classify specimens, make familial connections, understand the evolution of fishes, and springboard into further research. The taxonomy of fishes presented includes the anatomical characteristics, distribution, common and scientific names, and phylogenetic relationships for all 515 families of living fishes. Packed with representative species drawings and information on phylogentic relationships, this informative Fourth Edition features: * Both fossil and extant species * More than 500 illustrations * Fully vetted scientific and common names * An extensive bibliography
Download or read book Chondrichthyes written by Luis Fernando Rodrigues-Filho and published by BoD – Books on Demand. This book was released on 2017-12-20 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chondrichthyes are a group of cartilaginous fish, where we have sharks, rays, and chimeras as members. This group plays an important role in aquatic ecology, as they act as predators throughout the food chain (e.g., sharks). However, many populations of Chondrichthyes are threatened by several factors (increased direct fishing, high mortality rate as accompanying fauna, marine pollution, habitat destruction, etc.). These declines are evident in many parts of the world and have come to the attention of scientists, conservation organizations, the media, and the general public. Fisheries legislation regulating international fisheries markets has been amended to provide greater protection for this group along with other species of fish. However, little is known about these species, which reinforces the importance of studies in order to have a better understanding of the elasmobranch stocks, as well as to identify the influences of the anthropic action of fishing. In response to knowledge on the low sustainability of cartilaginous fish fisheries on a global scale, FAO has developed an international plan of action for the management and conservation of these fish, with the aim of developing and implementing national plans of action to ensure management and conservation of these stocks, having as main recommendation the collection of information about the Chondrichthyes, especially the sharks. Even so, this group is little known in terms of biodiversity, ecology, behavior, and a host of other characteristics relevant to this taxon, which is very worrying. Chondrichthyes - Multidisciplinary Approach attempts to portray to the readers up-to-date information on Chondrichthyes to promote an overview of the current taxon, serving as an indispensable source of access to more accurate and detailed information on shark rays and chimeras.

Download or read book Heads Jaws and Muscles written by Janine M. Ziermann and published by Springer. This book was released on 2019-01-23 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: The vertebrate head is the most complex part of the animal body and its diversity in nature reflects a variety of life styles, feeding modes, and ecological adaptations. This book will take you on a journey to discover the origin and diversification of the head, which evolved from a seemingly headless chordate ancestor. Despite their structural diversity, heads develop in a highly conserved fashion in embryos. Major sensory organs like the eyes, ears, nose, and brain develop in close association with surrounding tissues such as bones, cartilages, muscles, nerves, and blood vessels. Ultimately, this integrated unit of tissues gives rise to the complex functionality of the musculoskeletal system as a result of sensory and neural feedback, most notably in the use of the vertebrate jaws, a major vertebrate innovation only lacking in hagfishes and lampreys. The cranium subsequently further diversified during the major transition from fishes living in an aquatic environment to tetrapods living mostly on land. In this book, experts will join forces to integrate, for the first time, state-of-the-art knowledge on the anatomy, development, function, diversity, and evolution of the head and jaws and their muscles within all major groups of extant vertebrates. Considerations about and comparisons with fossil taxa, including emblematic groups such as the dinosaurs, are also provided in this landmark book, which will be a leading reference for many years to come.
Download or read book Reproduction Part A written by Peter K.T. Pang and published by Academic Press. This book was released on 1991-02-28 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vertebrate Endocrinology: Fundamentals and Biomedical Implications, Volume 4, Part A: Reproduction provides information pertinent to the structure and function of the vertebrate reproductive endocrinology. This book deals with a variety of subjects, including oocyte maturation, gestation, ovulation, vitellogenesis, spermatogenesis, and the maturation and aging of the reproductive system. Organized into seven chapters, this volume starts with an overview of the reproductive mechanisms and their underlying bases, with focus on the similarities between species. This book then discusses the factors of reproductive failure in many species, including failure of ovulation, abnormal fertilization, failure of fertilization, and failure of implantation. Other chapters explore the cellular, endocrinological, and molecular mechanisms that regulate oocyte maturation in mammals, which is directly stimulated by the need to improve human fertility and fecundity in domestic mammals. The final chapter deals with the aging of the brain–pituitary–gonadal axis in vertebrates. Reproductive endocrinologists and developmental neuroendocrinologists will find this book extremely useful.

Download or read book Rebels Scholars Explorers written by Annalisa Berta and published by JHU Press. This book was released on 2020-10-27 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unearthing the amazing hidden stories of women who changed paleontology forever. For centuries, women have played key roles in defining and developing the field of vertebrate paleontology. Yet very little is known about these important paleontologists, and the true impacts of their contributions have remained obscure. In Rebels, Scholars, Explorers, Annalisa Berta and Susan Turner celebrate the history of women "bone hunters," delving into their fascinating lives and work. At the same time, they explore how the discipline has shaped our understanding of the history of life on Earth. Berta and Turner begin by presenting readers with a review of the emergence of vertebrate paleontology as a science, emphasizing the contributions of women to research topics and employment. This is followed by brief biographical sketches and explanations of early discoveries by women around the world over the past 200 years, including those who who held roles as researchers, educators, curators, artists, and preparators. Forging new territory, Berta and Turner highlight the barriers and challenges faced by women paleontologists, describing how some managed to overcome those obstacles in order to build careers in the field. Finally, drawing on interviews with a diverse group of contemporary paleontologists, who share their experiences and offer recommendations to aspiring fossil hunters, they provide perspectives on what work still needs to be done in order to ensure that women's contributions to the field are encouraged and celebrated. Uncovering and relating lost stories about the pivotal contributions of women in vertebrate paleontology doesn't just make for enthralling storytelling, but also helps ensure a richer and more diverse future for this vibrant field. Illuminating the discoveries, collections, and studies of fossil vertebrates conducted by women in vertebrate paleontology, Rebels, Scholars, Explorers will be on every paleontologist's most-wanted list and should find a broader audience in the burgeoning sector of readers from all backgrounds eager to learn about women in the sciences.

Available in PDF, EPUB and Kindle. Book excerpt: From ancient megalodons to fearsome Great Whites, this book tells the complete, untold story of how sharks emerged as Earth’s ultimate survivors, by world-leading paleontologist John Long. “Will keep you on the edge of your seat from its first page to its last page.”—Jared Diamond, Pulitzer Prize–winning author of Guns, Germs, and Steel Sharks have been fighting for their lives for 500 million years and today are under dire threat. They are the longest-surviving vertebrate on Earth, outlasting multiple mass extinction events that decimated life on the planet. But how did they thrive for so long? By developing superpower-like abilities that allowed them to ascend to the top of the oceanic food chain. John Long, who for decades has been on the cutting edge of shark research, weaves a thrilling story of sharks’ unparalleled reign. The Secret History of Sharks showcases the global search to discover sharks’ largely unknown evolution, led by Long and dozens of other extraordinary scientists. They embark on digs to all seven continents, investigating layers of rock and using cutting-edge technology to reveal never-before-found fossils and the clues to sharks’ singular story. As the tale unfolds, Long introduces an enormous range of astonishing organisms: a thirty-foot-long shark with a deadly saw blade of jagged teeth protruding from its lower jaws, a monster giant clams crusher, and bizarre sharks fossilized while in their mating ritual. The book also includes startling new facts about the mighty megalodon, with its sixty-six-foot-long body, massive jaws, and six-inch serrated teeth. With insights into the threats to sharks today, how they contribute to medical advances, and the lessons they can teach us about our own survival, The Secret History of Sharks is a riveting look at scientific discovery with ramifications far beyond the ocean.
