Download or read book Zoogeography Taxonomy and Conservation of West Virginia s Ohio River Floodplain Crayfishes Decapoda Cambaridae written by Zachary J. Loughman and published by PenSoft Publishers LTD. This book was released on 2011-01-06 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: The crayfish fauna of West Virginia consists of 23 species and several undescribed taxa. Most survey efforts documenting this fauna have been conducted in lotic waterways throughout the Appalachian plateau, Allegheny Mountains, and Ridge and Valley physiographic provinces. Bottomland forests, swamps, and marshes associated with large river floodplains such as the Ohio River floodplain historically have been under-surveyed, though these habitats harbor the richest primary burrowing crayfish fauna in West Virginia. The crayfish fauna of West Virginia?s Ohio River floodplain was surveyed from 2004 through 2009.ÿ From this survey, nine species from four genera were documented inhabiting the floodplain. Zoogeography, biology, and conservation status is provided for the nine species encountered in the survey, as well as a review of crayfish collection methods and a dichotomous key to West Virginia Ohio River floodplain crayfish species.
Download or read book A Global Overview of the Conservation of Freshwater Decapod Crustaceans written by Tadashi Kawai and published by Springer. This book was released on 2016-10-26 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces updated information on conservation issues, providing an overview of what is needed to advance the global conservation of freshwater decapods such as freshwater crabs, crayfish, and shrimps. Biodiversity loss in general is highest in organisms that depend on intact freshwater habitats, because freshwater ecosystems worldwide are suffering intense threats from multiple sources. Our understanding of the number and location of threatened species of decapods, and of the nature of their extinction threats has improved greatly in recent years, and has enabled the development of species conservation strategies. This volume focuses on saving threatened species from extinction, and emphasizes the importance of the successful implementation of conservation action plans through cooperation between scientists, conservationists, educators, funding agencies, policy makers, and conservation agencies.

Download or read book Lifestyles and Feeding Biology written by Martin Thiel and published by Oxford University Press. This book was released on 2015-04-09 with total page 584 pages. Available in PDF, EPUB and Kindle. Book excerpt: This second volume in the Natural History of the Crustacea series examines how crustaceans-the different body shapes and adaptations of which are described in volume 1-make a living in the wide range of environments they inhabit, and how they exploit food sources. The contributions in the volume give synthetic overviews of particular lifestyles and feeding mechanisms, and offer a fresh look at crustacean life styles through the technological tools that have been applied to recent crustacean research. These include SEM (scanning electron microscope) techniques, micro-optics, and long-term video recordings that have been used for a variety of behavioral studies. The audience will include not only crustacean biologists but evolutionary ecologists who want to understand the diversification of particular life styles, ecologists who follow the succession of communities, biogeochemists who estimate the role of crustaceans in geochemical fluxes, and biologists with a general interest in crustaceans.
Download or read book Mammoth Cave written by Horton H. Hobbs III and published by Springer. This book was released on 2018-08-02 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reveals the science and beauty of Mammoth Cave, the world's longest cave, which has played an important role in the natural sciences. It offers a comprehensive and interdisciplinary treatment of the cave, combining insights from leading experts in fields ranging from archeology and cultural history to life science and geosciences. The first animals specialized for cave life in North America, including beetles, spiders, crayfish, and fish, were discovered in Mammoth Cave in the 1840s. It has also been used and explored by humans, including Native Americans, who mined its sulfate minerals and later African-American slaves, who made a map of the cave. More recent stories include 'wars' between commercial cave owners, epic exploration trips by modern cave explorers, and of course tourism. The first section of the book is an extensive description including maps and photos of the cave, its basic structural pattern, and how it relates to the surface landscape. The second section covers the human history of utilization and exploration of the cave, including mining, tourism, and medical experiments. Cave science is the topic of the third section, including geology, hydrology, mineralogy, climatology, paleontology, ecology, biodiversity, and microbiology. The fourth section looks to the future, with an overview of environmental issues facing Mammoth Cave managers. The book is intended for anyone interested in caves in general and Mammoth Cave in particular, experts in one discipline seeking information about other areas, and researchers and students interested in the many avenues of pursuit possible in Mammoth Cave.
Download or read book Evolutionary Ecology of Social and Sexual Systems written by J. Emmett Duffy and published by Oxford University Press. This book was released on 2007-09-06 with total page 519 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding of animal social and sexual evolution has seen a renaissance in recent years with discoveries of frequent infidelity in apparently monogamous species, the importance of sperm competition, active female mate choice, and eusocial behavior in animals outside the traditional social insect groups. Each of these findings has raised new questions, and suggested new answers, about the evolution of behavioral interactions among animals. This volume synthesizes recent research on the sexual and social biology of the Crustacea, one of the dominant invertebrate groups on earth. Its staggering diversity includes ecologically important inhabitants of nearly every environment from deep-sea trenches, through headwater streams, to desert soils. The wide range of crustacean phenotypes and environments is accompanied by a comparable diversity of behavioral and social systems, including the elaborate courtship and wildly exaggerated morphologies of fiddler crabs, the mysterious queuing behavior of migrating spiny lobsters, and even eusociality in coral-reef shrimps. This diversity makes crustaceans particularly valuable for exploring the comparative evolution of sexual and social systems. Despite exciting recent advances, however, general recognition of the value of Crustacea as models has lagged behind that of the better studied insects and vertebrates. This book synthesizes the state of the field in crustacean behavior and sociobiology and places it in a conceptually based, comparative framework that will be valuable to active researchers and students in animal behavior, ecology, and evolutionary biology. It brings together a group of internationally recognized and rising experts in fields related to crustacean behavioral ecology, ranging from physiology and functional morphology, through mating and social behavior, to ecology and phylogeny. Each chapter makes connections to other, non-crustacean taxa, and the volume closes with a summary section that synthesizes the contributions, discusses anthropogenic impacts, highlights unanswered questions, and provides a vision for profitable future research.
Download or read book The Invertebrates written by R. S. K. Barnes and published by John Wiley & Sons. This book was released on 2009-04-13 with total page 507 pages. Available in PDF, EPUB and Kindle. Book excerpt: The majority of undergraduate texts in invertebrate zoology (of which there are many) fall into one of two categories. They either offer a systematic treatment of groups of animals phylum by phylum, or adopt a functional approach to the various anatomical and physiological systems of the better known species. The Invertebrates is the first and only textbook to integrate both approaches and thus meet the modern teaching needs of the subject. This is the only invertebrate textbook to integrate systematics and functional approaches. The molecular systematics sections have been completely updated for the new edition. Strong evolutionary theme which reflects the importance of molecular techniques throughout. Distills the essential characteristics of each invertebrate group and lists diagnostic features to allow comparisons between phyla. New phyla have been added for the new edition. Stresses comparisons in physiology, reproduction and development. Improved layout and illustration quality. Second edition has sold 14000 copies. Nature of the first edition: 'Students will like this book. It deserves to succeed.'
