Book Description
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.

Book Description
This volume is based on a workshop "Modulation of Synaptic Transmission and Plasticity in Nervous Systems" held in n Ciocco, Castelvecchio, Pascoli, Italy, from September 8th to 13th, 1987. The purpose of the meeting was to bring together scientists working on plasticity in nervous systems on different levels. The contributions can be subgrouped into six fields of research: 1) Presynaptic Modulation of Chemical Neurotransmission 2) Postsynaptic Signal Transduction 3) Modulation of Synaptic Transmission and Plasticity in the Hippocampus 4) Modulation of Neuromuscular Transmission 5) Molecular and Cellular Analysis of Conditioning in Marine Snails 6) Analysis of Learning and Memory in Insects Understanding how nervous systems and in particular our brain processes and stores information has been a major challenge in science for centuries and will remain for some time to come. Not until recently neurobiologists agreed to seek plasticity of behavior primarily in the modulation of the properties of synapses between nerve cells. This is to be understood within the context provided by a neural circuitry. An important stimulus came from the work on the marine snail Aplysia, where learning processes can be described as a modulation of transmitter release, traced back to a complete chain of molecular events in an identified neuron. Learning became a topic of molecular biology. Three systems appear particularly promising for this approach: insects, in particular Drosophila, marine snails and the mammalian hippocampal tissue. Our views on neurotransmission have rapidly changed.

Book Description
Crawfish Frogs (Rana areolata) have been called the most secretive frog in North America, and it is unusual in the twenty-first century – in the most scientifically advanced country in the world – that basic discoveries can still be made on an animal that inhabits a quarter of the United States. This is not only a story of the biology of Crawfish Frogs, but a case study of discovery. This volume describes the life history and natural history critical to the survival of the endangered amphibian and recommends management actions to ensure persistence. The authors tell an optimistic conservation biology story and fill a gap between science and the public. The authors have compiled and summarized the peer-reviewed literature on the biology of Crawfish Frogs, which may be one of the most interesting frogs in North America (that nobody knows about). Key Features Recounts the story of an imperiled species and how to go about saving it Vividly brings science to life and makes it accessible Provides a popular account of natural history research and ecological fieldwork Related Titles D.

Book Description
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.

Book Description
Invasive species have come to dominate 3% of the Earth’s ice-free surface, constituting one of the most serious ecological and economic threats of the new millennium, and freshwater systems are particularly vulnerable. This book examines the identity, distribution, and impact of freshwater non-indigenous species and the dynamics of their invasion. It focuses on old and new invaders and provides a starting point for further research.
