Book Description
A Computer-Mapped Flora presents the study of county flora using electronic data processing methods to sort and codify the information gathered. This book also uses computer techniques for the construction of distribution maps that report the presence or absence of a species in a certain area and their major habitats. The book is comprised of 15 chapters. The first chapter is subdivided into two parts that discuss the previous work and a review and revision of old methods used in the study. The following paragraphs focus on the physical aspect of the topic. This volume includes chapters on the physical background, geology and soils, and historical geography. Also included in the book is a chapter dedicated to the historical survey of Warwickshire bryophytes. The following section focuses on the study and research aspect. Topics included are the recording and processing of data and habitat studies. The topics discussed in the subsequent chapters focus on plants, specifically flowering and vascular plants and bryophytes. Distribution maps, graph-plotted maps, and vascular plant checklists are some of the topics discussed. The book aims to be of service to botanists and other biologists outside of the British setting. This reference material will be helpful to other disciplines as the methods documented herein can also be applied to other studies and research.

Book Description
This volume records the proceedings of, and the papers read at, an international conference to consider the use of electronic data processing methods in the major taxonomic plant collections of Europe, primarily herbaria but also living collections. This conference took place at the Royal Botanic Gardens, Kew, from 3rd to 6th October, 1973. It was attended by some 90 delegates, observers and speakers, mainly from a wide range of the major European herbaria, but also from other interested institutions. The problem to be discussed was a big one. Taxonomic collections of the sorts mentioned above constitute the main centres for the scientific documentation of the flora of the world. With the extinction of so many species more or less imminently threatened, and with the modification or disappearance of so many vegetation types through the activities of man, the information contained in these collections grows in importance. Their aggregate size, in Europe, has been estimated at between 50 and 100 millions, and these are annually augmented at a rapid rate. Each specimen or living plant comprises a source of evidence and information represented both by the specimen itself and the associated information provided by the collector and subsequent investigators - identifications, field notes, records of subsequent research, etc. This associated information is known as the label data. Research on the taxonomy and geographical distribution of plants usually requires data from specimens stored in a number of institutions in different countries.

Book Description
The Sonoran Desert, a fragile ecosystem, is under ever-increasing pressure from a burgeoning human population. This ecological atlas of the region's plants, a greatly enlarged and full revised version of the original 1972 atlas, will be an invaluable resource for plant ecologists, botanists, geographers, and other scientists, and for all with a serious interest in living with and protecting a unique natural southwestern heritage. An encyclopedia as well as an atlas, this monumental work describes the taxonomy, geographic distribution, and ecology of 339 plants, most of them common and characteristic trees, shrubs, or succulants. Also included is valuable information on natural history and ethnobotanical, commercial, and horticultural uses of these plants. The entry for each species includes a range map, an elevational profile, and a narrative account. The authors also include an extensive bibliography, referring the reader to the latest research and numerous references of historical importance, with a glossary to aid the general reader. Sonoran Desert Plants is a monumental work, unlikely to be superseded in the next generation. As the region continues to attract more people, there will be an increasingly urgent need for basic knowledge of plant species as a guide for creative and sustainable habitation of the area. This book will stand as a landmark resource for many years to come.

Book Description
Originally published in 1981 Historical Plant Geography is an introductory treatment of historical plant geography and stresses the basic theoretical frame of the subject. The book is about neither the study of vegetation nor the concept of the ecosystem, instead focusing on the much older tradition concerned with analysing the geographical distribution of individual species and natural plant groups. Important areas are discussed, such as global plate tectonics and sea-floor spreading, plant maps are introduced and there is a basic treatment of recent advances in plant taxonomy. The book will appeal to students and academics of geography, botany, ecology and environmental sciences.

Book Description
Over the past four centuries botanists and gardeners in the British Isles have gathered, maintained and propagated many varying species of plants. Their work has been documented in innumerable books and articles which are often difficult to trace. The Dictionary of British and Irish Botanists and Horticulturalists represents a time-saving reference source for those who wish to discover more about the lives and achievements of the horticulturalists listed. The dictionary's utility comes not only from indicating the major publications of the named authors, but also the location of their herbaria and manuscripts.; The previous 1977 edition of the Dictionary has for many years been a much used source of information for botanists, botanic artists and archivists. In this revised edition the scope has been expanded to include among its 13,000 entries flower painters in addition to botanical artists over 1400 entries and, for the first time, garden designers.; Finally the Dictionary should have international appeal since so many botanists and gardeners worked on collective plants overseas, in particular in North America and the British Commonwealth.; Each entry gives, wherever possible, details of dates and places of birth and death, educational qualifications, professional posts, honours and awards, publications, location of plant collections, manuscripts, drawings and portraits. Its main function, however, is to provide further biographical references to books and periodicals. Comprehensive classified indices facilitate access by professions and activities, countries, and plant interests.

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
In recent years, the conservation of tropical forests has received worldwide publicity whereas effective forest management, particularly for timber extraction, has attracted little attention and gained some notoriety. The overall aim of the present paper was to examine how environmental micro-variation in the Chiquibul Forest Reserve of Belize can influence species distribution and thereby inform management strategy. The paper deals first with the background to forest management in Belize, then considers the methodology used in the present study and fin~~ly assesses the preliminary results. The specific objectives are: (1) to assess the effects of changing scale on the variability of selected individual soil properties in forest plots within the same vegetation class; and (2) to examine the variation in soil properties and tree species distribution, and to integrate environmental and ecological data over a range of scales. BACKGROUND Whereas the global and regional distribution of tropical forests is broadly governed by climatic and altitudinal variation, individual forest tracts need to consider a range of other, locally important factors to explain species distribution and change. With very high species diversity, tropical forests present a major challenge in the attempt to unravel controlling factors in distribution and growth (Swaine et aI. 1987). Research that attempts to explain diversity has looked at species distribution according to a range of factors, with a general recognition that soil fertility plays a significant if ill defined role (Swaine 1996).
