The Anacostia River is one of the country's most polluted and forgotten rivers. Industrialization and urbanization along the banks have led to the River's ecological degradation. Though extensive pollution exists along the River, the biological health of organisms in the watershed is poorly studied. The current study examined the consequences of early developmental exposure to Anacostia River water from Bladensburg Waterfront Park in zebrafish (Danio rerio). Water quality analysis identified 91% of contaminants as siloxane compounds. Chronic, 14-day exposure to Bladensburg Park water had variable effects on the anatomy and behavior of zebrafish larvae consistent with the absence of a stress response. These results contrast a previous study using water collected from the Washington Navy Yard, identifying differences in water quality along the Anacostia that have the potential to differentially impact fish species.

Completely revised and updated with 18 new chapters, this second edition includes contributions from over 75 international experts. Also, a Technical Review Board reviewed all manuscripts for accuracy and currency. Focusing on toxic substance and how they affect the ecosystems worldwide, the book presents methods for quantifying and measuring ecotoxicological effects in the field and in the lab, as well as methods for estimating, predicting, and modeling in ecotoxicology studies. This is the definitive reference for students, researchers, consultants, and other professionals in the environmental sciences, toxicology, chemistry, biology, and ecology - in academia, industry, and government.

Encyclopedia of Caves, Third Edition, provides detailed background information to anyone with a serious interest in caves. This includes students, both undergraduate and graduate, in the earth, biological and environmental sciences, and consultants, environmental scientists, land managers and government agency staff whose work requires them to know something about caves and the biota that inhabit them. Caves touch on many scientific interests in geology, climate science, biology, hydrology, archaeology, and paleontology, as well as more popular interests in sport caving and cave exploration. Case studies and descriptions of specific caves selected for their special features and public interest are also included. This book will appeal to these audiences by providing in-depth essays written by expert authors chosen for their expertise in their assigned subject. Features 14 new chapters and 13 completely rewritten chapters Contains beautifully illustrated content, with more than 500 color images of cave life and features Provides extensive bibliographies that allow readers to access their subject of interest in greater depth

The rapid development of nanoscience enables a technology revolution that will soon impact virtually every facet of the water sector. Yet, there is still too little understanding of what nanoscience and nanotechnology is, what can it do and whether to fear it or not, even among the educated public as well as scientists and engineers from other disciplines. Despite the numerous books and textbooks available on the subject, there is a gap in the literature that bridges the space between the synthesis (conventional and more greener methods) and use (applications in the drinking water production, wastewater treatment and environmental remediation fields) of nanotechnology on the one hand and its potential environmental implications (fate and transport of nanomaterials, toxicity, Life Cycle Assessments) on the other. Nanotechnology for Water and Wastewater Treatment explores these topics with a broad-based multidisciplinary scope and can be used by engineers and scientists outside the field and by students at both undergraduate and post graduate level.

Yeast Genetics: Methods and Protocols is a collection of methods to best study and manipulate Saccharomyces cerevisiae, a truly genetic powerhouse. The simple nature of a single cell eukaryotic organism, the relative ease of manipulating its genome and the ability to interchangeably exist in both haploid and diploid states have always made it an attractive model organism. Genes can be deleted, mutated, engineered and tagged at will. Saccharomyces cerevisiae has played a major role in the elucidation of multiple conserved cellular processes including MAP kinase signaling, splicing, transcription and many others. Written in the successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible protocols and notes on troubleshooting and avoiding known pitfalls. Authoritative and easily accessible, Yeast Genetics: Methods and Protocols will provide a balanced blend of classic and more modern genetic methods relevant to a wide range of research areas and should be widely used as a reference in yeast labs.

This book is the second volume of autobiographical essays by distinguished senior neuroscientists; it is part of the first collection of neuroscience writing that is primarily autobiographical. As neuroscience is a young discipline, the contributors to this volume are truly pioneers of scientific research on the brain and spinal cord. This collection of fascinating essays should inform and inspire students and working scientists alike. The general reader interested in science may also find the essays absorbing, as they are essentially human stories about commitment and the pursuit of knowledge. The contributors included in this volume are: Lloyd M. Beidler, Arvid Carlsson, Donald R. Griffin, Roger Guillemin, Ray Guillery, Masao Ito. Martin G. Larrabee, Jerome Lettvin, Paul D. MacLean, Brenda Milner, Karl H. Pribram, Eugene Roberts and Gunther Stent. Key Features * Second volume in a collection of neuroscience writing that is primarily autobiographical * Contributors are senior neuroscientists who are pioneers in the field

The focus of this book is on the more than 2000 caves of the Greenbrier Valley of West Virginia of which the 14 with lengths greater than 10 km have an aggregate length of 639 km. The major caves form the core part of sub-basins which drain to big springs and ultimately to the Greenbrier River. Individual chapters of this book describe each of the major caves and its associated drainage basin. The caves are formed in the Mississippian Greenbrier Limestone in a setting of undulating gentle folds. Fractures, lineaments and confining layers within the limestone are the main controlling factors. The caves underlie an extensive sinkhole plain which may relate to a major erosion surface. The caves are habitat for both aquatic and terrestrial organisms which are cataloged and described as are the paleontological remains found in some of the caves. The sinkhole plain of the Greenbrier karst and the underlying complex of cave systems are the end result of at least a ten million year history of landscape evolution which can be traced through the evolving sequence of cave passages and which is described in this book.

Anyone who requires detailed knowledge of the structures and functions of the human brain needs this self-test coloring book. It includes more than 350 illustrations that give a sharp and realistic view of the human brain and nervous system, examining its constituent parts and how they all work. The physical task of coloring in the illustrations makes an impression on your mind, allowing you to remember the shape, location, and purpose of each part of the brain. Pages lay flat for easy coloring, labels are left blank so you can test your knowledge as you color, and answers are located at the bottom of the page. After you’re finished, visualizing these areas becomes much easier, leading to greater memorization and recall. Medical and healthcare students—as well as practitioners—will want to get their hands on this concise, interactive reference to the fascinating human brain.
