Book excerpt: Vascular 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 or read book Histories of Technology the Environment and Modern Britain written by Jon Agar and published by UCL Press. This book was released on 2018-04-09 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: Histories of Technology, the Environment and Modern Britain brings together historians with a wide range of interests to take a uniquely wide-lens view of how technology and the environment have been intimately and irreversibly entangled in Britain over the last 300 years. It combines, for the first time, two perspectives with much to say about Britain since the industrial revolution: the history of technology and environmental history. Technologies are modified environments, just as nature is to varying extents engineered. Furthermore, technologies and our living and non-living environment are both predominant material forms of organisation – and self-organisation – that surround and make us. Both have changed over time, in intersecting ways. Technologies discussed in the collection include bulldozers, submarine cables, automobiles, flood barriers, medical devices, museum displays and biotechnologies. Environments investigated include bogs, cities, farms, places of natural beauty and pollution, land and sea. The book explores this diversity but also offers an integrated framework for understanding these intersections.

Download or read book The Lichens of Great Britain and Ireland written by Clifford W. Smith and published by . This book was released on 2009 with total page 1064 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Lichen Flora of Great Britain and Ireland published in 1992 was an outstanding achievement for British Lichenology. It was a pioneering work and the first of its type in Europe. This much enlarged revision reflects the considerable accumulation of new information that has occurred since the publication of the first edition and is symptomatic of the enormous advances in lichen taxonomy over the last two decades. There are keys to 327 genera and 1873 species, which is an increase of 386 species since it was first published. The publication provides detailed information on morphology, chemistry and distribution for each species written in language that is readily accessible, avoiding obscure terminology. Both the glossary and introductory sections have been expanded and the latter includes helpful advice on the identification and examination of lichens. The preparation of this new treatment has involved a large number of contributors both in the UK and overseas and represents the culmination of lichen studies at this time. This book is undoubtedly the standard work for the identification of lichens in Great Britain and Ireland and will be indispensable to all serious students of British, Irish and overseas lichenology and other biologists working in related fields of ecology, pollution, chemical and environmental studies."--Publisher's description.

Download or read book The Changing Wildlife of Great Britain and Ireland written by David L. Hawksworth and published by CRC Press. This book was released on 2003-06-26 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
