A unique and personal insight into the ecology and evolution of pollinators, their relationships with flowers, and their conservation in a rapidly changing world. The pollination of flowers by insects, birds and other animals is a fundamentally important ecological function that supports both the natural world and human society. Without pollinators to facilitate the sexual reproduction of plants, the world would be a biologically poorer place in which to live, there would be an impact on food security, and human health would suffer. Written by one of the world’s leading pollination ecologists, this book provides an introduction to what pollinators are, how their interactions with flowers have evolved, and the fundamental ecology of these relationships. It explores the pollination of wild and agricultural plants in a variety of habitats and contexts, including urban, rural and agricultural environments. The author also provides practical advice on how individuals and organisations can study, and support, pollinators. As well as covering the natural history of pollinators and flowers, the author discusses their cultural importance, and the ways in which pollinator conservation has been portrayed from a political perspective. The book draws on field work experiences in South America, Africa, Australia, the Canary Islands and the UK. For over 30 years the author has spent his career researching how plants and pollinators evolve relationships, how these interactions function ecologically, their importance for society, and how we can conserve them in a rapidly changing world. This book offers a unique and personal insight into the science of pollinators and pollination, aimed at anyone who is interested in understanding these fascinating and crucial ecological interactions.

This is tropical Africa's first Red Data book for plants. Cameroon contains tropical Africa's most species-diverse hotspots for plants; many are rare and threatened with extinction. In the book 815 species are documented as being threatened using IUCN global assessments, most being assessed for the first time. Short species descriptions to aid identification in the field are given, as well as notes on habitats and threats, together with distribution maps and management suggestions to assist better conservation.

It is a privilege to be asked and a pleasurable duty for me to write the foreword of this book. The conservation and wise utilisation of the humid tropical forests, a unique biome, are matters of great concern and importance to millions living within and around these forests and, perhaps, less directly, to the totality of mankind. These forests provide many essential products and services for mankind. The list is lengthy and need not be repeated here. Suffice it to say that there are not many aspects of human activity which do not utilise some of these products, services or derivatives therefrom. Yet it is the view of those most closely associated with the study of these forests that what is known is but a minuscule portion of whatthere is to know. The products and services now utilised, are perhaps some infinitesimal part of the full potential. All over the tropical world, however, these forests are being destroyed. At first, slowly, but now surely gathering tempo. This is true also of Ghana. Tracts offorest land are converted to other uses, often ephemeral and not sustained. Irreversible changes take place in our environment. The gains are shortlived, the losses unobtrusively accumulate and stay forever. The accelerating rate of deforestation, in the face of our relatively scanty knowledge of this biome, is indeed a sad reflection of the state of human affairs. It is in this setting that one welcomes this book by Messrs. J. B. Hall and M. D. Swaine.

In this volume, 24 flowering plant families comprising a total of 911 genera are treated. They represent the asterid order Lamiales except for Acanthaceae (including Avicenniaceae), which will be included in a later volume. Although most of the constituent families of the order have been recognized as being closely related long ago, the inclusion of the families Byblidaceae, Carlemanniaceae and Plocospermataceae is the result mainly of recent molecular systematic research. Keys for the identification of all genera are provided, and likely phylogenetic relationships are discussed extensively. To facilitate the recognition of relationships, families are cross-referenced where necessary. The wealth of information contained in this volume makes it an indispensable source for anybody in the fields of pure and applied plant sciences.
