Bird Census Techniques from the Author: Colin J. Bibby. Wild birds are counted for a wide variety of reasons and by a bewildering array of methods. However, detailed descriptions of the techniques used and the rationale adopted are scattered in the literature, and the newcomer to bird census work or the experienced bird counter in search of a wider view, may well have difficulty in coming to grips with the subject as a whole. While not an end in itself, numerical and distributional census work is a fundamental part of many scientific and conservation studies, and one in which the application of given standards is vital if results are not to be distorted or applied in a misleading way. This book provides a concise guide to the various census techniques and to the opportunities and pitfalls which each entails. The common methods are described in detail, and illustrated through an abundance of diagrams showing examples of actual and theoretical census studies. Anyone with a bird census job to plan should be able to select the method best suited to the study at hand, and to apply it to best effect within the limits inherent in it and the constraints of the particular study. The Royal Society for the Protection of Birds and the British Trust for Ornithology have for many years pioneered the collaboration of amateurs and professionals in various census studies. Three members of their staff, each with extensive field experience, now pool the knowledge of these investigations to lay the groundwork for sound census work in future years.

Practical Field Ecology from the Author: C. Philip Wheater. This book introduces experimental design and data analysis / interpretation as well as field monitoring skills for both plants and animals. Clearly structured throughout and written in a student-friendly manner, the main emphasis of the book concentrates on the techniques required to design a field based ecological survey and shows how to execute an appropriate sampling regime. The book evaluates appropriate methods, including the problems associated with various techniques and their inherent flaws (e.g. low sample sizes, large amount of field or laboratory work, high cost etc). This provides a resource base outlining details from the planning stage, into the field, guiding through sampling and finally through organism identification in the laboratory and computer based data analysis and interpretation. The text is divided into six distinct chapters. The first chapter covers planning, including health and safety together with information on a variety of statistical techniques for examining and analysing data. Following a chapter dealing with site characterisation and general aspects of species identification, subsequent chapters describe the techniques used to survey and census particular groups of organisms. The final chapter covers interpreting and presenting data and writing up the research. The emphasis here is on appropriate wording of interpretation and structure and content of the report.

Southwestern Desert Resources from the Author: William Lee Halvorson. Yet Matt Ridley does more than describe how things are getting better. He explains why. Prosperity comes from everybody working for everybody else. The habit of exchange and specialization---which started more than 100,000 years ago---has created a collective brain that sets human living standards on a rising trend. The mutual dependence, trust, and sharing that result are causes for hope, not despair. --

Raptors from the Author: Jon Hardey. This field guide is written for people who watch, survey or monitor birds of prey and contains detailed descriptions of survey methods for all species of raptor found regularly in Britain and Ireland. Written by a team from the Scottish Raptor Monitoring Group, this publication draws on the knowledge and experience of more than 300 raptor specialists. Chapters include the following topics: survey, surveillance and monitoring; population estimates; breeding season parameters; identification and breeding behaviours of raptors; good practice for fieldwork; and detailed species accounts. It includes a CD-ROM of raptor calls.

Taking Stock Of Nature from the Author: Anna Lawrence. In a world of increasing demands for biodiversity information, participatory biodiversity assessment and monitoring is becoming more significant. Whilst other books have focused on methods, or links to conservation or development, this book is written particularly for policy makers and planners. Introductory chapters analyze the challenges of the approach, the global legislation context, and the significance of the Millennium Ecosystem Assessment. Specially commissioned case studies provide evidence from 17 countries, by 50 authors with expertise in both biological and social sciences. Ranging from community conservation projects in developing countries to amateur birdwatching in the UK, they describe the context, objectives, stakeholders and processes, and reflect on the success of outcomes. Rather than advocating any particular approach, the book takes a constructively critical look at the motives, experiences and outcomes of such approaches, with cross-cutting lessons to inform planning and interpretation of future participatory projects and their contribution to policy objectives.

Wildlife Study Design from the Author: Michael L. Morrison. We developed the first edition of this book because we perceived a need for a compilation on study design with application to studies of the ecology, conser- tion, and management of wildlife. We felt that the need for coverage of study design in one source was strong, and although a few books and monographs existed on some of the topics that we covered, no single work attempted to synthesize the many facets of wildlife study design. We decided to develop this second edition because our original goal – synthesis of study design – remains strong, and because we each gathered a substantial body of new material with which we could update and expand each chapter. Several of us also used the first edition as the basis for workshops and graduate teaching, which provided us with many valuable suggestions from readers on how to improve the text. In particular, Morrison received a detailed review from the graduate s- dents in his “Wildlife Study Design” course at Texas A&M University. We also paid heed to the reviews of the first edition that appeared in the literature.

Monitoring Ecological Change from the Author: Ian F. Spellerberg. The state of ecosystems, biological communities and species are continuously changing as a result of both natural processes and the activities of humans. In order to detect and understand these changes, effective ecological monitoring programmes are required. This book offers an introduction to the topic and provides both a rationale for monitoring and a practical guide to the techniques available. Written in a nontechnical style, the book covers the relevance and growth of ecological monitoring, the organizations and programmes involved, the science of ecological monitoring and an assessment of methods in practice, including many examples from monitoring programmes around the world. Building on the success of the first edition, this edition has been fully revised and updated with two additional chapters covering the relevance of monitoring to the reporting of the state of the environment, and the growth of community based ecological monitoring.
