R631 Discovery Miles 6 310 Ships in 18 - 22 working days

This book is the fifth companion volume to 'An Introduction To Using GIS In Marine Biology'. It is designed to augment the information on using GIS in marine biology provided in that book, and, indeed, to be used alongside it rather than to be used independently as a stand-alone volume. Therefore, this book will be of most interest to those who have already read 'An Introduction To Using GIS In Marine Biology'. This book consists of five exercises covering the practical use of GIS in marine biology using ESRI's ArcGIS(r) 10.2 software. These exercises are based around creating maps for reports and presentations. They range from making a map template which allows you to quickly make new maps in a standard format to creating a custom legend which allows you to repeatedly apply the same symbols to multiple data layers and making multi-part maps . The exercises are designed to be followed in the order they are presented, and work with a specific data set, which can be download separately for free. Working through these five exercises will help the novice GIS user obtain experience making maps for reports and presenations, and so develop their GIS skills. Unlike most other GIS tutorials, this information is specifically presented in a marine biological context and all the exercises use real data from a marine biological study. Therefore, these exercises are more likely to provide the kind of experience in using GIS that marine biologists will find useful and applicable to their own research. These exercises are presented in the same easy-to-follow flow diagram-based format first introduced in the 'How To...' section of 'An Introduction To Using GIS In Marine Biology'. They are accompanied by images which show the user how their GIS project should look as they progress through the exercises, allowing them to compare their own work to the expected results. This is part of the PSLS series of books which use Task-Oriented Learning (TOL) to teach the practical application of research skills to the life sciences. This involves demonstrating how these skills can be used in the specific circumstances in which they are likely to be required rather than concentrating on teaching theoretical frameworks or on teaching skills in a generic or abstract manner. By seeing how the similar processes are used to achieve a variety of different goals within a specific field, it becomes easier for the reader to identify the general rules behind the practical application of these processes and, therefore, to transfer them to novel situations they may encounter in the future.

R1,872 Discovery Miles 18 720 Ships in 18 - 22 working days

This innovative volume provides a blueprint for managing the challenges of ocean conservation using marine historical ecology--an interdisciplinary area of study that is helping society to gain a more in-depth understanding of past human-environmental interactions in coastal and marine ecosystems, and the ecological and social outcomes associated with these interactions.
Developed by groundbreaking practitioners in the field, "Marine Historical Ecology" highlights the innovative ways that historical ecology can be applied to improve conservation and management efforts in the oceans.
The book focuses on four key challenges that confront marine conservation: (1) recovering endangered species, (2) conserving fisheries, (3) restoring ecosystems, and (4) engaging the public. Chapters emphasize real-world conservation scenarios appropriate for students, faculty, researchers, and practitioners in marine science, conservation biology, natural resource management, paleoecology, and marine and coastal archaeology. By focusing on success stories and applied solutions, this volume delivers the required up-to-date science and tools needed for restoration and protection of ocean and coastal ecosystems.

From the days of discovery and colonization, America has looked to the sea. In times of stress the sea has been our ally, and in times of peace, a source of our prosperity. Sometimes hostile and sometimes generous in its moods, the ocean always has offered its abundant resources in countless ways. But only recently have we begun to perceive its true potential. The driving force and urgency of our new concern for the sea stem from the changing character of the world itself-from mounting economic needs, from congested populations, from our own deteriorating shores. It is now nearly 10 years since reports by the National Academy of Science and the U.S. Navy focused attention upon the vital import of our undeveloped marine resources. The intervening decade has been marked by a mounting interest and activity. Further reports, studies, and statements have poured forth in profusion, representing the experience, the views, and the best judgment of the outstanding experts of the country. Throughout this period a voluminous legislative record testifies also to a growing Congressional concern, which culminated in June 1966 in the Marine Resources and Engineering Development Act, expressing a conviction and defining a national purpose: 1) a conviction that the time had arrived for this country to give serious and systematic attention to our marine environment and to the potential resources of the oceans, and 2) a national determination to take the steps necessary to stimulate marine exploration, science, technology, and financial investment on a vastly augmented scale.

From deep ocean trenches and the geographical poles to outer space, organisms can be found living in remarkably extreme conditions. This book provides a captivating account of these systems and their extraordinary inhabitants, 'extremophiles'. A diverse, multidisciplinary group of experts discuss responses and adaptations to change; biodiversity, bioenergetic processes, and biotic and abiotic interactions; polar environments; and life and habitability, including searching for biosignatures in the extraterrestrial environment. The editors emphasize that understanding these systems is important for increasing our knowledge and utilizing their potential, but this remains an understudied area. Given the threat to these environments and their biota caused by climate change and human impact, this timely book also addresses the urgency to document these systems. It will help graduate students and researchers in conservation, marine biology, evolutionary biology, environmental change and astrobiology better understand how life exists in these environments and their susceptibility or resilience to change.

The deep ocean is by far the planet's largest biome and holds a wealth of potential natural assets. Human exploitation of the deep ocean is rapidly increasing whilst becoming more visible to many through the popular media, particularly film and television. The scientific literature of deep-sea exploitation and its effects has also rapidly expanded as a direct function of this increased national and global interest in exploitation of deep-sea resources, both biological (e.g. fisheries, genetic resources) and non-biological (e.g. minerals, oil, gas, methane hydrate). At the same time there is a growing interest in deep-sea contamination (including plastics), with many such studies featured in high profile scientific journals and covered by global media outlets. However, there is currently no comprehensive integration of this information in any form and these topics are only superficially covered in classic textbooks on deep-sea biology. This concise and accessible work provides an understanding of the relationships between biodiversity and ecosystem functioning, both at the seafloor and in the water column, and how these might be affected as a result of human interaction, exploitation and, ultimately, environmental change. It follows a logical progression from geological and physical processes, ecology, biology, and biogeography, to exploitation, management, and conservation. Natural Capital and Exploitation of the Deep Ocean is aimed at marine biologists and ecologists, oceanographers, fisheries scientists and managers, fish biologists, environmental scientists, and conservation biologists. It will also be of relevance and use to a multi-disciplinary audience of fish and wildlife agencies, NGOs, and government departments involved in deep-sea conservation and management.

Dr Alverson's story covers his early life experiences, through high school, World War II, his education and his involvement in State, Federal and International fisheries science and management. His career and story cover the period (1950-2000) during which world fisheries would explode from small boat coastal activities to distant water fleets of large vessels. World catches would increase over 300% after WWII and most of the worlds oceans and seas would be heavily exploited. Overfishing and impacts on coastal fisheries would lead the world community to seek new laws for the harvest of ocean fisheries and result in unilateral extension of national jurisdictions over ocean space. The growth of environmental movement in the later half of the 20th century would lead to conflicts between fishing and conservation groups resulting in changes in national and international fish policies. The book tracks many of these developments and DR Alverson's personal involvements and experiences during the traumatic period of world fishery expansion. During the course of his life marine fisheries resource would be seen as the great source of world protein to feed the worlds hungry and later as overfished and polluted.

Sub-Class?Cirripedia. Crustacea attached by the anterior end of the head, by cement proceeding from a modified portion of the ovaria; archetype composed of seventeen segments, with the three first of large size, and almost always developed into a carapace, not wholly exuviated, and capable of various movements; antenna none; eyes rudimentary; mouth prominent, formed by the partial confluence of the labrum, palpi, mandibles, and two pairs of maxilla; thorax attached to the internal sternal surface of the carapace, generally bearing six pairs of captorial, biramous, multi-articulated limbs; abdomen generally rudimentary; branchiae, lohen present, attached to the under sides of the carapace; generally bisexual, when unisexual, males epizoic on the female; penis single, generally probosciformed, seated at the posterior end of the abdomen; oviducts none; metamorphoses complex. Within the memory of many living naturalists, Cirripedes were universally looked on as belonging to the Molluscous kingdom; nor was this surprising, considering the fixed condition of their shells, and the degree of external resemblance between, on the one hand, Lepas and Teredo, and on the other hand, between Balanus and a Mollusc compounded of a patella and chiton. It is remarkable that this external false appearance overbore, even in the mind of Cuvier, his knowledge of their internal structure, namely, their lateral jaws, articulated appendages, and regular gan- glionic nervous system, which now strike us as such conclusive evidence of their position in the great Articulate kingdom. Straus was, I believe, the first who, in 1819, maintained that Cirripedes were most closely allied to Crustacea. But this view was disregarded, until J.

Water Chemistry provides students with the tools necessary to understand the processes that control the chemical species present in waters of both natural and engineered systems. After providing basic information about water itself and the chemical composition of water in environmental systems, the text covers the necessary theory (thermodynamics, activity, and kinetics) and background material to solve problems. It emphasizes that both equilibrium and kinetic processes are important in aquatic systems. The book does not merely focus on inorganic constituents, but also on the fate and reactions of organic chemicals.
The solving of quantitative equilibrium and kinetic problems using mathematical, graphical, and computational tools is emphasized throughout presentations on acid-base chemistry, complexation of metal ions, solubility of minerals, and oxidation-reduction reactions. The use of these problem-solving tools is then extended in the presentation of topics relevant to natural systems, including dissolved oxygen, nutrient chemistry, geochemical controls on chemical composition, photochemistry, and natural organic matter. The kinetics and equilibria relevant to engineered systems (e.g., chlorination and disinfection chemistry, sorption and surface chemistry) and organic contaminant chemistry are also discussed. Numerous in-chapter examples that show the application of theory and demonstrate how problems are solved using algebraic, graphical, and computer-based techniques are included. Examples are relevant to both natural waters and engineered systems.
