Book Description
Chart Number One is essential to correct and accurate use of nautical charts. More than a chart, it is a book that defines the symbols, abbreviations and terms used on charts. It also provides important information about buoys, light visibility (range) and aids to navigation. This new and improved edition from Paradise Cay is a complete and accurate high quality reproduction of information provided by NOAA and NIMA.
Sturgeon biodiversity and conservation
Author: Vadim J. BirsteinPublisher: Springer Science & Business Media
ISBN: 0792345177
Category : Nature
Languages : en
Pages : 444
Book Description
This volume presents a synthesis of basic biological and conservation data for more than 30 species of sturgeons (Acipenseridae), paddlefishes (Polyodontidae) and their fossil allies in the order Acipenseriformes. Since the Jurassic, the four families of sturgeon-like fish have been restricted to the Holarctic, where until very recently they flourished in most major river systems. Today, however, virtually all species of sturgeons and paddlefishes face difficult conservation issues. Papers in the first section of this volume examine paleontology, systematics, evolution and basic biology of Acipenseriformes. The second section of this volume details current conservation status for most of the world's living species of Acipenseriformes. These papers mark the first attempt to make such a global review of recent data from across the northern hemisphere. The emerging picture is discouraging, for negative anthropogenic impacts range from overfishing to water pollution, to dams and water diversion projects, and all species are threatened to some degree. The third section of the volume considers specific human impacts and responses to conservation issues. These include: the Aral Sea ecological disaster and its impact on native sturgeons; a review of methods for restoring sturgeon populations; the use of molecular techniques in developing conservation strategies; the extreme sensitivity of sturgeons and paddlefishes to overfishing; and the history of a recently convicted caviar poaching ring. The volume's summary reviews the status of all extant species and notes future directions for research on behavior, ecology and population biology that could lead to better co-ordinated international conservation efforts.
Fish Migration and Fish Bypasses
Author: Mathias JungwirthPublisher: Wiley
ISBN: 9780852382530
Category : Technology & Engineering
Languages : en
Pages : 448
Book Description
International Conference on Fish Migration and Bypass Channels held in Vienna in September 1996. It covers the range of fish pass technologies currently in use throughout the world and attempts to develop a wider, more ecological perspective on this formerly engineering-orientated discipline. Emphasis is placed on enhancing an understanding of fish migration behaviour, and achieving optimum design to meet the behavioural requirements of all known migratory species. Additional attention is paid to comparing the European trend towards constructing nature-like bypass channels with the highly technical solutions dominant in North America.
Measures of Environmental Performance and Ecosystem Condition
Author: National Academy of EngineeringPublisher: National Academies Press
ISBN: 0309522331
Category : Science
Languages : en
Pages : 309
Book Description
When Cleveland's Cuyahoga River caught fire in 1969, no environmental measurements were necessary to know the seriousness of the problem. Incidents like the Cuyahoga fire raise an important question: Can catastrophes-in-the-making be detected early enough to be prevented? For those in industry, such disasters point to the need for measures that can improve the environmental performance of processes, products, business practices, and linked industrial systems. In Measures of Environmental Performance and Ecosystem Condition, experts share their insights on environmental metrics. The volume explores the most productive relationship between measures of environmental performance and measures of ecosystem conditions. It reviews current approaches, evaluates structures for business decisionmaking, and includes a matrix for determining the environmental performance of industrial facilities. Case studies include: Development and application of a water-quality rating scheme for streams and reservoirs in the Tennessee Valley. Three years of successful experience with waste metrics at 3M. The book covers the range of environmental performance and condition metrics, from the use of material flow data to monitor environmental performance at the national level to the use of bioassays to measure the toxicity of industrial effluents. This book offers something for everyone--policymakers, executives, engineers, managers, and advocates--with a stake in the measurement of environmental performance and ecological conditions.
