Ecological Methods by the late T.R. E. Southwood and revised over the years by P. A. Henderson has developed into a classic reference work for the field biologist. It provides a handbook of ecological methods and analytical techniques pertinent to the study of animals, with an emphasis on non-microscopic animals in both terrestrial and aquatic environments. It remains unique in the breadth of the methods presented and in the depth of the literature cited, stretching right back to the earliest days of ecological research. The universal availability of R as an open source package has radically changed the way ecologists analyse their data. In response, Southwood's classic text has been thoroughly revised to be more relevant and useful to a new generation of ecologists, making the vast resource of R packages more readily available to the wider ecological community. By focusing on the use of R for data analysis, supported by worked examples, the book is now more accessible than previous editions to students requiring support and ideas for their projects. Southwood's Ecological Methods provides a crucial resource for both graduate students and research scientists in applied ecology, wildlife ecology, fisheries, agriculture, conservation biology, and habitat ecology. It will also be useful to the many professional ecologists, wildlife biologists, conservation biologists and practitioners requiring an authoritative overview of ecological methodology.

This classic text, whose First Edition one reviewer referred to as "the ecologists' bible," has been substantially revised and rewritten. Not only have the advances made in the field since the Second Edition been taken into account, but the scope has been explicitly extended to all macroscopic animals, with particular attention being paid to fish as well as other vertebrates. Ecological Methods provides a unique synthesis of the methods and techniques available for the study of populations and ecosystems. Techniques used to obtain both absolute and relative population estimates are described, and approaches to the direct measurement of births, deaths, migration and the construction and interpretation of life tables are reviewed. The text is extensively illustrated, clearly describing a wide range of equipment and methods of analysis. Comprehensive and up-to-date bibliographies to each chapter fully cover the relevant literature, and references are given to available computer programs and internet addresses. The book has an active web site providing additional illustrations, details of equipment and programs, and references to work published since the revision was completed. Like the earlier editions, this book will be an indispensable source of reference to researchers and students at all levels in the fields of ecology, entomology and zoology. Completely revised and rewritten edition of a classic. Scope extended to all macroscopic animals, notably fish and other vertebrates. Active web site displaying additional material. References to computer programmes and internet addresses throughout the text. Affordable paperback.

The virtual impossibility of extracting the many different species from a habitat with equal efficiency by a single method (e.g. Nef, 1960). 1.1 Population estimates Population estimates can be classified into a number of different types; the most convenient classification is that adopted by Morris (1955), although he used the terms somewhat differently in a later paper (1960). 1.1.1 Absolute and related estimates The animal numbers may be expressed as a density per unit area of the ground of the habitat. Such estimates are given by nearest neighbour and related techniques (Chapter 2), marking and recapture (Chapter 3), by sampling a known fraction of the habitat (Chapter 4-6) and by removal sampling and random walk techniques (Chapter 7). Absolute population The number of animals per unit area (e.g. hectare, acre). It is almost impossible to construct a budget or to study mortality factors without the conversion of population estimates to absolute figures, for not only do insects often move from the plant to the soil at different developmental stages, but the amount of plant material is itself always changing. The importance of obtaining absolute estimates cannot be overemphasized.

This extensive third revision of Southwood's influential Ecological Methods retains the general objectives and style of the previous editions and extends its coverage to include more up-to-date methods, such as computational techniques, distance sampling, aquatic methods and GIS. In combining both theory and pratical methods this book provides unique coverage of an area of importance to students and researchers of ecology alike.

There are few books available that provide a good introduction tothe methods and techniques for ecological research. This book willbe invaluable to lecturers teaching field courses and studentsundertaking project work in ecology. Each chapter will focus on an ecological technique. It will havean introductory section that describes the ecological principlesand theory. This will then be followed by example applications.These will focus on three most common habitats where teachers takestudents for fieldwork; the seashore, ponds and lakes, fields andwoodland. Gives specific worked examples from the main ecosystems usedfor undergraduate study - seashore, lakes/ponds, field andwoodland. Only introductory text specifically focused on fieldtechniques. Great 'how-to' guide that will show student exactly how tocarry out each method. Only text to emphasise the principles behind the techniques -taking a methods based approach rather than a taxonomic approach(eg chapters split into population measures, biodiversity measures,species richness measures rather than methods for invertebrates,methods for mammals, methods for birds etc). Greater emphasis on the equipment involved - how to make it,where to buy it. Good references to further reading and advancedtechniques.
