Acoustic Ecology of European Bats
As nocturnal flying mammals, bats have developed a unique and very efficient means of navigating in the dark: sonar, or echolocation. Although the acoustic signals they emit are inaudible to the human ear, they can be perceived, recorded, and analyzed with appropriate equipment and software. In this book, Michel Barataud synthesizes more than two decades of research on acoustic ecology and bat sonar physics and detection. Highlighting technological advances, Barataud shows how he has developed an ever more efficient identification method using an initial, purely auditory approach (a "bat detector") complemented by computer-assisted analysis of the ultrasonic signals. By following Barataud's method and the data provided, readers will be able to identify about 85% of European bat acoustic records, including all the most widespread species, as well as carry out non-invasive bat inventories and research. Including a DVD of more than 300 audio samples and scatter diagrams of sonar emissions to aid in species identification, and featuring a contribution by bat sonar pioneer Yves Tupinier, Acoustic Ecology of European Bats will be an invaluable resource for all scientists of Chiroptera.

Locust Control Handbook
It is of paramount importance to improve application techniques when controlling locust outbreaks in developing countries. Most available documents and publications on locust control deal mainly with insecticides, rather than application techniques and the required control equipment. The present guide book is designed to make up for this oversight. Basic principles for conducting spraying operations, descriptions of spraying equipment, especially for ultra low volume spraying, and specific locust control techniques are described in detail. The document explains how to get the most from treatments while minimizing the adverse effects to man and the environment. This book is aimed at decision-makers and all those involved in locust control who wish to improve their knowledge of application techniques.

The Ecology of Invasions by Animals and Plants
n this book I have tried to bring together ideas from three different Istreams of thought with which I have been closely concerned during the last thirty years or so. The first is faunal history, usually regarded as a purely academic subject, but to some of whose events can be traced a number of the serious dislocations taking place in the world today. The second is ecology, particularly the structure and dynamics of populations. The third is conservation. I first published a few ideas about the signifi cance of invasions in 1943, in a war-time review called Polish Science and Learning, under the title of 'The changing realms of animal life'. Since then I have had the opportunity to think pretty hard about conservation, while taking part in the planning and development of the Nature Con servancy. In March 1957 I gave three broadcasts in the B. B. C. 's Third Programme, under the title of 'Balance and Barrier'. These were sub sequently printed in The Listener (1957, Vol. 57, pp. 514-15,556-7,596-7, and 600). The present book is essentially an expansion of these. I am extremely grateful to Mr James C. Thornton and Dr John Simons for in planning and giving these talks. advice and help In preparing this book I have had invaluable assistance from the staff of the Bureau of Animal Population. Miss C. M. Gibbs typed the fair copy. Miss M.

The Atlas of European Mammals
This volume presents maps of 194 species plotted on a 50km UTM grid and entirely based on field observations. Over 93,000 records are mapped with separate symbols for dat collected before or after 1970. Where appropriate, recent extinctions have been taken into account.
