Book Description
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.

Book Description
The Atlas plots the results of the survey organised by the BTO and the IWC during the years 1968-72. Over 250 maps show the distribution of 218 species. This companion volume to The Atlas of Wintering Birds in Britain and Ireland is derived from yearly surveys of breeding birds in Britain and Ireland during 1968-72, organised by the British Trust for Ornithology and the Irish Wildbird Conservancy. Each of the 3,862 10-km squares of Britain and Ireland was visited during the five years and the resulting records (over 285,000) are summarised in the maps. The full-page maps plot the known distribution of all but 11 of the 229 breeding species located during the survey period. Each map has an accompanying text which describes the species' habitat, the problems involved in proving breeding, the historical background to the species' range and any changes in its numbers. The probable reasons for these changes are discussed and an attempt made to assess the total number of birds for each species. Jacket design by Robert Gillmor.

Book Description
Many different kinds of animals have adopted a parasitic life style on the skin and gills of marine and freshwater fishes, including protozoans, flatworms, leeches, a range of crustaceans and even some vertebrates (lampreys). There is a parasitic barnacle, described first in the 19th century by Charles Darwin, fish lice that change sex and bivalve molluscs parasitic only when young. This book explores for the first time in one volume, the remarkable biology of these little known and frequently bizarre animals. The following closely interwoven themes are considered for each group of parasites: how they find their hosts, how they attach, feed and reproduce, the damage they inflict and how the host’s immune system retaliates. Based on the British fauna, but extending where appropriate to examples from North America, Australia and elsewhere, the book is essential reading, not just for the professional parasitologist, but also for anyone interested in fishes and in this neglected field of British natural history. With the enquiring naturalist in mind, terms and concepts are explained as they arise, backed up by a glossary, and the text is liberally illustrated. An introductory chapter on fish biology sets the scene and common fish names are used throughout, as well as scientific names.

Book Description
Logs, stones and the like provide an interesting interface between the damp depths of the soil and the drier open ground surface, offering refuges for a fascinating array of animals. The communities of organisms that live beneath them are little noticed and even less studied, yet the potential for ecological work here is great. Some of the animals are relatively large and frequently not difficult to find. They exhibit a wide range of lifestyles – from slow slugs or snails to very fast centipedes, from generalist to specialist feeders and from herbivores to carnivores. With chapters covering the cryptosphere environment, species groups, identification, guidelines and ideas for further research, this much-expanded and updated new edition also includes extensive, easy-to-use, comprehensively illustrated keys. Ground-surface debris can be found almost anywhere, often presenting highly accessible microhabitats for study and bringing immediate rewards to the curious: here is the ideal tool to unlock these worlds.

Book Description
Over the past 20 years dramatic declines have taken place in UK insect populations. Eventually, such declines must have knock-on effects for other animals, especially high profile groups such as birds and mammals. This authoritative, yet accessible account details the current state of the wildlife in Britain and Ireland and offers an insight into the outlook for the future. Written by a team of the country's leading experts, it appraises the changes that have occurred in a wide range of wildlife species and their habitats and outlines urgent priorities for conservation. It includes chapters on each of the vertebrate and major invertebrate groups, with the insects covered in particular depth. Also considered are the factors that drive environmental change and the contribution at local and government level to national and international wildlife conservation. Essential reading for anyone who is interested in, and concerned about, UK wildlife.
