Book Synopsis Handbook of Genetics by : Robert King
Download or read book Handbook of Genetics written by Robert King and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 664 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the first four volumes of the Handbook of Genetics is to bring together collections of relatively short, authoritative essays or an notated compilations of data on topics of significance to geneticists. Many of the essays will deal with various aspects of the biology of certain species or species groups selected because they are favorite subjects for genetic investigation in nature or the laboratory. Often there will be an encyclo pedic amount of information available on such species, with new papers appearing daily. Most of these will be written for specialists in a jargon that is bewildering to a novice, and sometimes even to a veteran geneticist working with evolutionarily distant organisms. For such readers what is needed is a written introduction to the morphology, life cycle, reproductive behavior, and culture methods for the species in question. What are its particular advantages (and disadvantages) for genetic study, and what have we learned from it? Where are the classic papers, the key bibli ographies, and how does one get stocks of wild type or mutant strains? Lists giving the symbolism and descriptions for selected mutants that have been retained and are thus available for future studies are provided whenever possible. Genetic and cytological maps, mitotic karyotypes, and haploid DNA values are also included when available. Volume 4 deals with certain vertebrate species that have been studied in considerable detail from the standpoint of genetics or molecular cytogenetics. Such data are available for only a relatively few vertebrates.
Download or read book Malformed Frogs written by Michael Lannoo and published by Univ of California Press. This book was released on 2008-08-04 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: The widespread appearance of frogs with deformed bodies has generated much press coverage over the past decade. Frogs with extra limbs or digits, missing limbs or digits, or misaligned appendages raise an alarming question: "Are deformed humans next?" Taking a fresh look at this disturbing environmental problem, this reference provides a balanced overview of the science behind the malformed frog phenomenon. Bringing together data from ecology, parasitology, and other disciplines, Michael Lannoo considers the possible causes of these deformities, tells which frogs have been affected, and addresses questions about what these malformations might mean to human populations. Featuring high-quality radiographic images, Malformed Frogs suggests that our focus should be on finding practical solutions, a key component of which will be controlling chemical, nutrient, and pesticide runoff into wetlands.
Book Synopsis Mosaic Landscapes and Ecological Processes by : L. Hansson
Download or read book Mosaic Landscapes and Ecological Processes written by L. Hansson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: This series presents studies that have used the paradigm of landscape ecology. Other approaches, both to landscape and landscape ecology are common, but in the last decade landscape ecology has become distinct from its predecessors and its contemporaries. Landscape ecology addresses the relationships among spatial patterns, temporal patterns and ecological processes. The effect of spatial configurations on ecological processes is fundamental. When human activity is an important variable affecting those relationships, landscape ecology includes it. Spatial and temporal scales are as large as needed for comprehension of system processes and the mosaic included may be very heterogeneous. Intellec tual utility and applicability of results are valued equally. The Inter national Association for Landscape Ecology sponsors this series of studies in order to introduce and disseminate some of the new knowledge that is being produced by this exciting new environmental science. Gray Merriam Ottawa, Canada Foreword This is a book about real nature, or as close to real as we know - a nature of heterogeneous landscapes, wild and humanized, fine-grained and coarse-grained, wet and dry, hilly and flat, temperate and not so temper ate. Real nature is never uniform. At whatever spatial scale we examine nature, we encounter patchiness. If we were to look down from high above at a landscape of millions of hectares, using a zoom lens to move in and out from broad overview to detailed inspection of a square meter we would see that patterns visible at different scales overlay one another.
Book Synopsis California Amphibian and Reptile Species of Special Concern by : Robert C. Thomson
Download or read book California Amphibian and Reptile Species of Special Concern written by Robert C. Thomson and published by Univ of California Press. This book was released on 2016-06-21 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most important hotspots of herpetological biodiversity in the United States, California is home to many endemic amphibians and reptiles found nowhere else on earth. Many of these taxa have unique ecological and morphological specializations, and their management is an important conservation challenge. Increasing climate change impacts, human development, and extreme drought mean many of these species face an ever-greater risk of extinction. California Amphibian and Reptile Species of Special Concern provides an up-to-date synthesis of the current state of knowledge regarding the biology and conservation risks faced by 45 of California’s most sensitive amphibian and reptile species. With the goal of enhancing management based on the best available science, the authors developed a novel set of risk metrics to identify special concern species and the threats they face, including population declines, range size and restrictions, and ecological specializations and niche restrictions. In addition to detailed species accounts, this book provides a quantitative analysis of the conservation status and pressing management issues facing individual species and the state’s amphibian and reptile fauna as a whole. The volume focuses on identifying threats, concrete recommendations for management and recovery, and future research needs. The text is complemented by detailed distribution maps, color photos, and graphs. Written in nontechnical language, California Amphibian and Reptile Species of Special Concern will be a valuable resource to a broad range of users from resource managers, field biologists, and academic herpetologists to students and recreational naturalists. Published in association with the California Department of Fish and Wildlife.
Book Synopsis Chromosome Atlas: Fish, Amphibians, Reptiles, and Birds by : Kurt Benirschke
Download or read book Chromosome Atlas: Fish, Amphibians, Reptiles, and Birds written by Kurt Benirschke and published by Springer. This book was released on 2013-11-16 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the publication of the first Atlas of Mammalian Chromosomes in 1967 the continuous compilation of mammalian karyotypes has become a useful instrument in cytologic and taxonomic studies. Technical advances in preparing mitotic cells from nonmammalian vertebrates have since allowed a better comparison of taxa in fishes, amphibia, reptiles, and birds. In these fields the literature is also widely scat tered; and it has become difficult to survey such information, published as well as unpublished, by nonspecialists. These were among the reasons for the new endeavor of compiling a chromosome atlas for nonmammalian vertebrates. An annual publication is planned with presentation of between 10 and 15 karyotypes from each class. In this second volume, 52 species are presented. For convenience in future colation, the numbering system employs class abbreviations, viz. , P-Pisces, Am-Amphibia, R-Reptilia, and Av-Aves. Within each class, the numbers are necessarily consecutive. In general the karyotypes are laid out following the format employed in An Atlas of Mammalian Chromosomes. Whenever possible both sexes are represented, even though sexual chromosomal dimorphism is not (currently) evident. When the sex chromosomes are known, they are so indicated by conventional nomenclature (XX/XY or ZW /ZZ). In the karyotypes of birds the so-called microchromosomes are grouped together at the end without an attempt at complete enumeration, which is presently impossible. They are usually considered as acrocentrics, but a few are distinctly biarmed.

Download or read book Ranaviruses written by Matthew J. Gray and published by Springer. This book was released on 2015-05-01 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first book on ranaviruses. Ranaviruses are double-stranded DNA viruses that cause hemorrhagic disease in amphibians, reptiles, and fish. They have caused mass die-offs of ectothermic vertebrates in wild and captive populations around the globe. There is evidence that this pathogen is emerging and responsible for population declines in certain locations. Considering that amphibians and freshwater turtles are suitable hosts and the most imperiled vertebrate taxa in the world, ranaviruses can have significant impacts on biodiversity and ecosystem function. Additionally, many fish that are raised in aquaculture facilities and traded internationally are suitable hosts; thus, the potential economic impact of ranaviruses is significant. Ranaviruses also serve as a model for replication and gene function of large double-stranded DNA viruses. There is an urgent need to assemble the contemporary information on ranaviruses and provide guidance on how to assess their threats in populations. Through the Global Ranavirus Consortium, 24 experts from six countries were organize to write this volume, the first book on ranaviruses. The book begins with a discussion on the global extent of ranaviruses, case histories of infection and disease in ectothermic vertebrates, and current phylogeny. Basic principles of ranavirus ecology and evolution are covered next, with a focus on host-pathogen interactions and how the virus emerges in its environment. There are two chapters that will discuss the molecular biology of ranaviruses, host response to infection, and the genes responsible for immune system evasion. One chapter establishes standards for testing for infection and diagnosing ranaviral disease. The book ends by providing guidance on how to design ranavirus surveillance studies and analyze data to determine risk, and discussing the role of the Global Ranavirus Consortium in organizing research and outreach activities.
Book Synopsis Development of Auditory and Vestibular Systems by : Raymond Romand
Download or read book Development of Auditory and Vestibular Systems written by Raymond Romand and published by Academic Press. This book was released on 2014-05-23 with total page 563 pages. Available in PDF, EPUB and Kindle. Book excerpt: Development of Auditory and Vestibular Systems fourth edition presents a global and synthetic view of the main aspects of the development of the stato-acoustic system. Unique to this volume is the joint discussion of two sensory systems that, although close at the embryological stage, present divergences during development and later reveal conspicuous functional differences at the adult stage. This work covers the development of auditory receptors up to the central auditory system from several animal models, including humans. Coverage of the vestibular system, spanning amphibians to effects of altered gravity during development in different species, offers examples of the diversity and complexity of life at all levels, from genes through anatomical form and function to, ultimately, behavior. The new edition of Development of Auditory and Vestibular Systems will continue to be an indispensable resource for beginning scientists in this area and experienced researchers alike. - Full-color figures illustrate the development of the stato-acoustic system pathway - Covers a broad range of species, from drosophila to humans, demonstrating the diversity of morphological development despite similarities in molecular processes involved at the cellular level - Discusses a variety of approaches, from genetic-molecular biology to psychophysics, enabling the investigation of ontogenesis and functional development

Download or read book The Photo Ark written by Joel Sartore and published by National Geographic Books. This book was released on 2017 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book of photography represents National Geographic's Photo Ark, a major cross-platform initiative and lifelong project by photographer Joel Sartore to make portraits of the world's animals -- especially those that are endangered. His message: to know these animals is to save them. Sartore intends to photograph every animal in captivity in the world. He is circling the globe, visiting zoos and wildlife rescue centers to create studio portraits of 12,000 species, with an emphasis on those facing extinction. He has photographed more than 6,000 already and now, thanks to a multi-year partnership with National Geographic, he may reach his goal. This book showcases his animal portraits: from tiny to mammoth, from the Florida grasshopper sparrow to the greater one-horned rhinoceros. Paired with the prose of veteran wildlife writer Douglas Chadwick, this book presents an argument for saving all the species of our planet.
