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.

Bird Monitoring Methods from the Author: Gillian Gilbert. First published by the RSPB in 1998, this book is a practical guide to surveying and monitoring techniques for use in the breeding season - in assessing breeding success as well as population levels - and during the winter. It gives instructions for more than 120 UK bird species, mainly those of conservation concern. Methods used in the UK's main national bird monitoring schemes are also outlined with advice on how to participate in them. In addition, the publication provides advice on the reliability of the methods, sampling, statistics and species protection. An essential reference for all involved in bird monitoring programmes. This is a reprint edition of 1901930033 published in 1998.

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.

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.

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.

Mosaic Techniques Traditions from the Author: Sonia King. With the breathtaking work of hundreds of artists on display throughout, this visually arresting volume showcases mosaics from all corners of the globe and teaches the skills needed to produce 15 beautiful pieces of your own. The history of the art, tools and materials, and techniques come first: bases, adhesives, and grout; shaping and placing tesserae; practical and artistic design considerations; and several methods of creating the actual mosaic. Put that information to use on an array of magnificent international projects, all beautifully illustrated and with the level of difficulty noted. Five mosaics from Europe include a lovely and easy Blue Willow Tray and French birdhouse. An American-inspired Flutterby Garden Stake made of mirror simply sparkles.

Natural Language Processing With Python from the Author: Steven Bird. This book offers a highly accessible introduction to natural language processing, the field that supports a variety of language technologies, from predictive text and email filtering to automatic summarization and translation. With it, you'll learn how to write Python programs that work with large collections of unstructured text. You'll access richly annotated datasets using a comprehensive range of linguistic data structures, and you'll understand the main algorithms for analyzing the content and structure of written communication. Packed with examples and exercises, Natural Language Processing with Python will help you: Extract information from unstructured text, either to guess the topic or identify "named entities" Analyze linguistic structure in text, including parsing and semantic analysis Access popular linguistic databases, including WordNet and treebanks Integrate techniques drawn from fields as diverse as linguistics and artificial intelligence This book will help you gain practical skills in natural language processing using the Python programming language and the Natural Language Toolkit (NLTK) open source library. If you're interested in developing web applications, analyzing multilingual news sources, or documenting endangered languages -- or if you're simply curious to have a programmer's perspective on how human language works -- you'll find Natural Language Processing with Python both fascinating and immensely useful.
