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.

This is an updated version of the best selling first edition, Ecological Census Techniques, with updating, some new chapters and authors. Almost all ecological and conservation work involves carrying out a census or survey. This practically focussed book describes how to plan a census, the practical details and shows with worked examples how to analyse the results. The first three chapters describe planning, sampling and the basic theory necessary for carrying out a census. In the subsequent chapters international experts describe the appropriate methods for counting plants, insects, fish, amphibians, reptiles, mammals and birds. As many censuses also relate the results to environmental variability, there is a chapter explaining the main methods. Finally, there is a list of the most common mistakes encountered when carrying out a census.

Monitoring has become fashionable. Business now talks about monitoring its activities, efficiency, costs and profits. The National Health Service is monitoring general practices and hospitals; it is keen to have more information about efficiency and the duration of stay of patients in different hospitals undergoing different types of treatment. These activities are usually carried out in relation to specific objectives with the aim of making activities more cost effective and competitive. Does the same apply in biology, ecology and nature conservation? Or, are we still enjoying conducting field surveys for the fun of it, at best with rather vague objectives and saying to our colleagues that we do our work because we need to know what is there? This book is an opportunity to consider some of the reasons why monitoring is important, how it differs from survey, how it may be able to answer specific questions and help with site management or problem solving. It will explore some of the taxa that are suitable for recording and how you may actually set about doing it. It is not intended as a catalogue of techniques but we will in each chapter give you sources of material so that with the minimum of effort you will be able to proceed with an efficient, relevant and not too time consuming monitoring programme. Some of the points that you need to consider before starting are also set down in the synthesis at the end of the book.

The genesis of this volume was in a one-day meeting arranged under the auspices of the Nathematical Ecology Group, jointly of the British Region of the Biometric Society and the British Ecological Society, and held in the Natural History Museum in London on the 4th May 1982. The object of the meeting was to bring together individuals from different dis ciplines but with a common interest in ornithology. In this volume we have tried to preserve the flavour of the meeting so that all but two of the papers read or pre sented as posters can be found here. The two papers that have not been included have since been published elsewhere: see Birkhead and Nettleship (1983) and Cav~ (1983). Further papers have been added to the volume from contributors who were unable to attend the London meeting, or were unable to present a paper there. All of the papers were refereed by ourselves. A volume which contains papers by both statisticians and non-statisticians is inevitably going to be variable with regard to the depth and range of statistical techniques used. Thus non-statisticians are likely to find some of the papers written by statisticians difficult at times, and conversely statisticians n2Y find that they would have treated some problems differently from non-statisticians. It is hoped, however, that this volun~ will increase awareness of the interests and problems (including solutions), in the general area of ornithology, and stimulate cross-fertilisation of ideas.

In the face of so many unprecedented changes in our environment, the pressure is on scientists to lead the way toward a more sustainable future. Written by a team of ecologists, Monitoring Animal Populations and Their Habitats: A Practitioner’s Guide provides a framework that natural resource managers and researchers can use to design monitoring programs that will benefit future generations by distilling the information needed to make informed decisions. In addition, this text is valuable for undergraduate- and graduate-level courses that are focused on monitoring animal populations. With the aid of more than 90 illustrations and a four-page color insert, this book offers practical guidance for the entire monitoring process, from incorporating stakeholder input and data collection, to data management, analysis, and reporting. It establishes the basis for why, what, how, where, and when monitoring should be conducted; describes how to analyze and interpret the data; explains how to budget for monitoring efforts; and discusses how to assemble reports of use in decision-making. The book takes a multi-scaled and multi-taxa approach, focusing on monitoring vertebrate populations and upland habitats, but the recommendations and suggestions presented are applicable to a variety of monitoring programs. Lastly, the book explores the future of monitoring techniques, enabling researchers to better plan for the future of wildlife populations and their habitats. Monitoring Animal Populations and Their Habitats: A Practitioner’s Guide furthers the goal of achieving a world in which biodiversity is allowed to evolve and flourish in the face of such uncertainties as climate change, invasive species proliferation, land use expansion, and population growth.

« Think about how we know about past events in human history (e.g., the expansion of the Roman Empire, or the American Revolution). What types of records document those events? Now think about Earth's history, specifically the past environmental or climatic conditions at times before recorded human history. What records might there be of such conditions? Make a list of your ideas. n assemblage of five major types of natural archives of Earth's environmental and climatic history. What common feature(s) do each of these paleoclimate archives share? an assemblage of 5 major types of natural records, or archives, of Earth's environmental and climatic history. Just like a diary or other historical document, the layers in these natural archives contain indirect evidence (i.e., proxies) about past conditions and events, recorded in a sequential order. The evidence is specific to a certain time period and may be general or very detailed, depending on the rate that information was recorded. The faster the rate at which the recorder grew (trees and corals), accumulated (snow and ice), or was deposited (sedimentary sequences), the more detailed the record is, and the higher its resolution. For example, a record in which an annual signal can observed has a very high resolution. In contrast, if the finest observable details are on the order of a million years, then that record would have a low resolution. »--
