DOWNLOAD EBOOKAnother volume in the popular New Naturalist Series, this book covers all aspects of the plant life of Britain and Ireland. Michael Proctor, an expert in his field, discusses the development of the landscape of Britain and Ireland from prehistoric times, including the influence of people and their agricultural practices on the vegetation. He provides a comprehensive account of all the different types of plant habitat in Britain and Ireland: from woodlands and scrubland to meadows and grasslands, from wetlands and peatlands to heaths, and from the mountain vegetation to the sea coast. He examines the history and ecology of each of these habitats, and describes the rich variety of flora found living there. The author concludes with an account of the changes to our landscape which have taken place during the twentieth century, and prospects for the future, including the effects of environmental change.

DOWNLOAD EBOOKVascular plant hybrids are numerous and constitute an important feature of our vegetation, but all too often they have been neglected by botanists. Some hybrids between native species are rare, sterile and ephemeral, but others reproduce vegetatively or by seed and have spread beyond the areas where their parents coexist. In addition, numerous hybrids have escaped from gardens to become established in the wild. Interspecific hybridisation is particularly significant as it represents a major evolutionary pathway in flowering plants; frequently it alters the characteristics of both native and alien taxa and it generates new species. The hybrid flora of the British Isles has been studied in more detail than that of any other region, and it therefore provides an ideal opportunity to study the occurrence of hybrids in wild vegetation. This book provides detailed accounts of the 909 hybrids reliably recorded in the wild in the British Isles. Of particular interest to BSBI members are the comprehensive identification notes, including a summary of the differences from the parents, enabling naming and recording of hybrids to a degree not attainable previously. The habitats of the hybrids are outlined and detailed accounts of their distributions provided, with notes on the discovery of many hybrids. There are 388 novel maps illustrating the records of the commoner hybrids in relation to those of their parents. Known chromosome numbers are given for each hybrid and its parents, and information is provided on the hybrid's fertility/sterility and its capacity for vegetative reproduction. Experimental and molecular studies of the hybrids in the British Isles and elsewhere in their ranges are summarised. Briefer notes are given on a further 156 hybrids, including some which are erroneously or doubtfully recorded and others which might potentially occur as escapes from cultivation.

DOWNLOAD EBOOKFollowing rigorous testing throughout Britain and Ireland over the last 10 years, this second edition is a much revised version with re-written keys, additional species, phenology and, of course, many new novel identification characters. A few new illustrations have been added where space allows. In addition, the nomenclature has been updated in line with modern taxonomy. Each key has been carefully reviewed and revamped so this version aims to be quicker and more comprehensive in detail than its predecessor, greatly improving on the original work. Additional floral and fruiting characters have been added for some of the more difficult species making it more handy for casual field use.

DOWNLOAD EBOOKPeriodic 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.
