This book brings together a diverse array of authors, expertise, and assessors that discuss technical developments to improve the construction, population, and dissemination of biodiversity information. It is designed to inform students and researchers of biodiversity about the changes and challenges that need to be understood by everyone in this information age.
Download or read book Database Systems in Science and Engineering written by J.R Rumble and published by CRC Press. This book was released on 1990-01-01 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computerized databases provide a powerful everyday tool for data handling by scientists and engineers. However, the unique nature of many technical tasks requires a specialized approach to make use of the many powerful commercial database tools now available. Using these tools has proved difficult because database technology is often shrouded in layers of jargon. An essential guide for scientists and engineers who use computers to avoid drowning in a flood of data, Database Systems in Science and Engineering dispels the myths associated with database design and breaks the barriers to successful databases. Using the language of scientists and engineers, this book explains concepts and problems, offers practical steps and solutions, and provides new ideas for better data handling. The first part of the book presents an overview of technical databases using examples taken from real applications and the current state of technical databases. The second part covers the computer implementation of technical databases, including examples and the necessary computer science theory to form a sound background. The authors confront the many difficulties that arise in the design and implementation of a realistic database and offer solutions to these challenges. Before beginning any database project, scientists and engineers should read this book to understand how to make every database project successful through careful planning, good design, and efficient use of database tools.
Download or read book Biodiversity in Drylands written by Moshe Shachak and published by Oxford University Press on Demand. This book was released on 2005 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biodiversity in Drylands, the first internationally based synthesis volume in the Long-Term Ecological Research (LTER) Network Series, unifies the concepts of species and landscape diversity with respect to deserts. Within this framework, the book treats several emerging themes, among them: � how animal biodiversity can be supported in deserts � diversity's relation to habitat structure, environmental variability, and species interactions � the relation between spatial scale and diversity � how to use a landscape simulation model to understand diversity � microbial contributions to biodiversity in deserts � species diversity and ecosystem processes � resource partitioning and biodiversity in fractal environments � effects of grazing on biodiversity � reconciliation ecology and the future of conservation management In the face of global change, integration is crucial for dealing with the problem of sustaining biodiversity. This book promises to be a vital resource for students, researchers, and managers interested in integrative species, resource, and landscape diversities.
Download or read book Birds and Climate Change written by James W. Pearce-Higgins and published by Cambridge University Press. This book was released on 2014-06-12 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the red grouse to the Ethiopian bush-crow, bird populations around the world can provide us with vital insights into the effects of climate change on species and ecosystems. They are among the best studied and monitored of organisms, yet many are already under threat of extinction as a result of habitat loss, overexploitation and pollution. Providing a single source of information for students, scientists, practitioners and policy-makers, this book begins with a critical review of the existing impacts of climate change on birds, including changes in the timing of migration and breeding and effects on bird populations around the world. The second part considers how conservationists can assess potential future impacts, quantifying how extinction risk is linked to the magnitude of global change and synthesising the evidence in support of likely conservation responses. The final chapters assess the threats posed by efforts to reduce the magnitude of climate change.
Download or read book Community Food Webs written by Joel E. Cohen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food webs hold a central place in ecology. They describe which organisms feed on which others in natural habitats. This book describes recently discovered empirical regularities in real food webs: it proposes a novel theory unifying many of these regularities, as well as extensive empirical data. After a general introduction, reviewing the empirical and theoretical discoveries about food webs, the second portion of the book shows that community food webs obey several striking phenomenological regularities. Some of these unify, regardless of habitat. Others differentiate, showing that habitat significantly influences structure. The third portion of the book presents a theoretical analysis of some of the unifying empirical regularities. The fourth portion of the book presents 113 community food webs. Collected from scattered sources and carefully edited, they are the empirical basis for the results in the volume. The largest available set of data on community food webs provides a valuable foundation for future studies of community food webs. The book is intended for graduate students, teachers and researchers primarily in ecology. The theoretical portions of the book provide materials useful to teachers of applied combinatorics, in particular, random graphs. Researchers in random graphs will find here unsolved mathematical problems.

This book was released on 2007 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: The African Water Resource Database (AWRD) is a set of data and custom-designed tools, combined in a geographic information system (GIS) analytical framework, aimed at facilitating responsible inland aquatic resource management with a focus on inland fisheries and aquaculture. It thus provides a valuable instrument to promote food security. The AWRD data archive includes an extensive collection of datasets covering the African continent, including: surface waterbodies, watersheds, aquatic species, rivers, political boundaries, population density, soils, satellite imagery and many other physiographic and climatological data. This technical paper is the second of two publications about the AWRD, and it includes a technical manual for spatial analysts and a workbook for university students and teachers. The first part of this technical paper is available separately (ISBN 9789251057407).

Download or read book Animal Talk written by Penelope Smith and published by Simon and Schuster. This book was released on 2008-06-30 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: A straightforward, easy-to-understand book that teaches you how to directly communicate with animals. Animal Talk teaches you how to open the door to your animal friends’ hearts and minds without resorting to magic tricks or wishful thinking. Every creature can be reached through telepathic communication—from your tabby cat or cockatiel to the wasps that build nests in the eaves of your home or even the common flea—you just have to be open to the idea, and mind-to-mind communication will be in your grasp. In addition to an entire chapter devoted to teaching people how to develop mind-to-mind communication with animals, Animal Talk includes a discussion of freedom, control, and obedience, understanding behaviors from the animal’s point of view, how to handle upsets between animals, tips on nutrition for healthier pets, and the special relationship between animals and children.
Download or read book Linking Species Ecosystems written by Clive G. Jones and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 403 pages. Available in PDF, EPUB and Kindle. Book excerpt: I was asked to introduce this volume by examining "why a knowledge of ecosys tem functioning can contribute to understanding species activities, dynamics, and assemblages." I have found it surprisingly difficult to address this topic. On the one hand, the answer is very simple and general: because all species live in ecosystems, they are part of and dependent on ecosystem processes. It is impossible to understand the abundance and distribution of populations and the species diversity and composition of communities without a knowledge of their abiotic and biotic environments and of the fluxes of energy and mat ter through the ecosystems of which they are a part. But everyone knows this. It is what ecology is all about (e.g., Likens, 1992). It is why the discipline has retained its integrity and thrived, despite a sometimes distressing degree of bickering and chauvinism among its various subdisciplines: physiological, be havioral, population, community, and ecosystem ecology.
Download or read book The Ecological Paradigm in Seafood Security written by Saleem Mustafa. and published by Universiti Malaysia Sabah Press. This book was released on 2021-06-06 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: The importance of seafood in global food security and economy cannot be overemphasized. Capture fisheries and aquaculture supply about 154 million tons of fish annually, with a total value of US$217.5 billion. Aquaculture’s contribution to this production and value is 90.4 million tons and US$144.4 billion, respectively. Billions of people depend to varying degrees on seafood for dietary protein. Development of these two sectors has not happened without environmental problems and, therefore, adaptive management is required to ensure sustainability. A major conservation intervention and measures for mitigating the effects of climate change are needed for sustaining the ability of marine ecosystems to withstand the fishing pressure. Likewise, new approaches and technological adaptations will contribute greatly to sustainability of aquaculture. These are the issue which deserve serious attention since, in terms of human nutrition and economy, the role of seafood sector is growing rapidly. This book delves upon the three seafood production systems – capture fisheries, aquaculture and sea ranching, elaborates the pertinent issues and presents scientific reasons for integrating ecological perspectives in management to address some of the major problems constraining their growth. The significance of a paradigm shift by way of removing negatively interacting factors among these sectors with positive synergies with their inherent elements of sustainability is also discussed. Consistency of these approaches with the triple bottom line vision of development instead of exclusive focus on seafood production in isolation with environmental homeostasis is explicitly explained.

Download or read book Cryptic Species written by Alexandre K. Monro and published by Cambridge University Press. This book was released on 2022-09-08 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cryptic species are organisms which look identical, but which represent distinct evolutionary lineages. They are an emerging trend in organismal biology across all groups, from flatworms, insects, amphibians, primates, to vascular plants. This book critically evaluates the phenomenon of cryptic species and demonstrates how they can play a valuable role in improving our understanding of evolution, in particular of morphological stasis. It also explores how the recognition of cryptic species is intrinsically linked to the so-called 'species problem', the lack of a unifying species concept in biology, and suggests alternative approaches. Bringing together a range of perspectives from practicing taxonomists, the book presents case studies of cryptic species across a range of animal and plant groups. It will be an invaluable text for all biologists interested in species and their delimitation, definition, and purpose, including undergraduate and graduate students and researchers.
