This book describes and illustrates in detail the 760 species of mosses currently known to occur in the British Isles and incorporates the most up-to-date information available on classification and nomenclature, together with recent synonyms. The species descriptions provide information on frequency, ecology, geographical relationships and distribution, including information on protected species and those species at risk. For many species there are footnotes to aid identification. In addition to the species descriptions there are descriptions of families and genera and also introductory information on conservation, collection, preservation and examination of material, together with advice on using the keys. An artificial key to genera provides the only workable comprehensive key published in the English language. This second edition incorporates the very considerable advances in our knowledge of mosses made in the last quarter of the twentieth century and will provide a unique resource for all concerned with these fascinating organisms.

Pictures, painted and carved in caves and on open rock surfaces, are amongst our loveliest relics from prehistory. This pioneering set of sparkling essays goes beyond guesses as to what the pictures mean, instead exploring how we can reliably learn from rock-art as a material record of distant times: in short, rock-art as archaeology. Sometimes contact-period records offer some direct insight about indigenous meaning, so we can learn in that informed way. More often, we have no direct record, and instead have to use formal methods to learn from the evidence of the pictures themselves. The book's eighteen papers range wide in space and time, from the Palaeolithic of Europe to nineteenth-century Australia. Using varied approaches within the consistent framework of informed and proven methods, they make key advances in using the striking and reticent evidence of rock-art to archaeological benefit.

The chapters in this book were developed from some of the lectures presented at a sym posium at the XX International Congress of Entomology held in Florence, Italy in August 1996. The purpose of the symposium was to discuss the impact of evolving modern agricultural landscapes on the insect species, of both economic and ecological importance, that utilize that habitat. Agricultural policy, to some extent, influences the choices that farmers make and thereby the shape of the agricultural landscape. In order to move toward more sustainable agro ecosystems future policy makers will have to consider the history of land use, consumer demands for both environmentally sound and affordable products, and the conservation of biological diversity. I would hope the information contained in this book will help stimulate discussion about the consequences of policy decisions on our agricultural landscapes and their insect inhabitants. I thank all the speakers from the symposium and in particular those that have been able to contribute chapters to this book. There have been many delays, most due to circumstances beyond anyone's control. I would like to express my appreciation to Gloria Verhey and Patrick Dumont for taking care of the book in these final months.

Periodic comprehensive overviews of the status of the diverse organisms that make up wildlife are essential to determining trends, threats and future prospects. Just over 25 years ago, leading authorities on different kinds of wildlife came together to prepare an assessment of their status of a wide range of organisms in Great Britain and Ireland in The Changing Flora and Fauna of Britain, also edited by Professor David L. Hawksworth CBE. Now, in The Changing Wildlife of Great Britain and Ireland, he has gathered together some of the original and also new contributors to review changes since that time and look to the future. Contributions range from viruses, diatoms, fungi, lichens, mites and nematodes; through butterflies, dragonflies, flies and slugs; to flowering plants, ferns, mammals, birds and fish. The state of knowledge in different groups is assessed, and the effectiveness of statutory and other measures taken to safeguard wildlife considered. The picture is far from bleak, ameliorating sulphur dioxide levels have benefited sensitive lichens and mosses in a dramatic way, water quality improvement has been beneficial, there have been few certain extinctions and rediscoveries of species thought to have been lost. Biodiversity Action Plans have also benefited targeted species, but habitat restoration and management for some is not always good for others. But there are worrying trends in declining populations, with an increasing number being regarded as threatened or endangered, especially in agricultural areas, and where woodland management has changed, particular threats from introduced species, and concern over the effects of climate change. Some of the smaller organisms remain poorly known, a situation unlikely to change as expertise in many is scant or being lost. This stock-check and look to the future will be a key source book to conservationists, naturalists, and professional biologists for many years to come.
