Book Description
Originally published in 1982, The Masterpiece of Nature examines sex as representative of the most important challenge to the modern theory of evolution. The book suggests that sex evolved, not as the result of normal Darwinian processes of natural selection, but through competition between populations or species - a hypothesis elsewhere almost universally discredited. The book also discusses the nature of sex and its consequences for the individual and for the population, as well as various other theories of sex. Since the value of these theories is held to reside wholly in their ability to predict the patterns of sexuality observed in nature, the book seeks to provide an extensive review of the circumstances in which sexuality is attenuated or lost throughout the animal kingdom, and these facts are then used to weigh up the merits of the rival theories. This book will be of interest to researchers in the area of genetics, ecology and evolutionary biology.

Book Description
Elm, one of the three principal landscape trees of England, differs from the others in its complex variability and its intricate relationship with human settlement. Originally published in 1983, the present book covers all its aspects: its history, its use and distribution by man from prehistoric times onwards, its vernacular names, the numerous organisms associated exclusively with it and its place in English literature and the visual arts. The book will be of value to anyone with an interest in the English landscape. It is of particular relevance to botanists, foresters, archaeologists, historical linguists, zoologists, students of English literature and the fine arts, and workers in the areas of conservation and town and country planning.

Book Description
The first book ever on the much maligned nettles of the world presents a story of these followers of mankind and his cattle throughout history. This study centres on the most abundant and sub-cosmopolitan common stinging nettle (Urtica dioica), but also deals with other nettles throughout the world. Tropical tormentors rich in species include the notorious nettle trees with their formidable stings which fascinated the Europeans after their discovery by botanists on the round-the-world trips of exploration in the 17-19th centuries. Many people on their travels will have met the nettle trees of the Indo-Malay region and other stinging nettles in North and South America, India, etc., which sting and have beautiful flowers but are called nettles; these are also dealt with. The first microscopists and their descriptions of the beautiful stinging hair; the uncovering of the mechanism of its action and the more recent elucidation of the toxins causing the characteristic symptoms is a fascinating one and takes up 3 chapters. The book includes the 100 major scientific works published on the common stinging nettle and never brought to the notice of the general public before. The author spent six years studying the ecology of the nettle patch, its invertebrate herbivores (mainly insects) and vertebrate herbivores (cattle, deer, etc.,) and their interactions with other plants: its secret life is recorded in line drawings and photographs (1000+ individual items). It was not possible to publish these in colour but they are in full colour on a CD-ROM (300 dpi) at the back of the book. Covered also are nettle folklore, fibre use in World War I & II, as a food, fodder, herbal medicine, growth as a competitor plant, habitats, sex (unique exploding stamens), breeding systems, variation, evolution etc.!! Some the world's most beautiful butterflies would not exist without nettles.
