This book has been produced with the aim of stimulating the general naturalist to take a closer look at the bumps and lumps that make up the fascinating world of plant galls. Induced by a variety of insects and other organisms and ranging from tiny pimples to bizarre and often very attractive and exquisitely sculptured growths, plant galls are mystery to many people, but they offer a fascinating field of study for both botanists and zoologists. Galls can be found on a very wide range of both woody and herbaceous plants, with over 50 different kinds occurring on Britain's oak trees alone, and there is still much to be learned about even the commonest examples. An introduction to the nature of plant galls and their formation Brief descriptions of some of the organisms that cause or induce galls Superb photographs of just over 200 of the commonest or most conspicuous of Britain's 1,000 or so plant galls, arranged according to their host plants to aid field identification Descriptions of these galls and the life histories of the organisms that cause them

A much-needed new study on plant galls growths on plants formed of plant tissue that are caused by other organisms. Most naturalists have come across oak apples, robin s pincushions, marble galls and witches brooms, a few of the more familiar examples of the strange growths that are plant galls. They are beautiful, often bizarre and colourful, and amazingly diverse in structure and in the organisms which cause them. They have been known since ancient times and have attracted superstitions and folk customs. Both the ancient Greeks and the Chinese used them in herbal medicine, and until well into the nineteenth century, they had a variety of commercial uses: important for dyeing cloth, tanning leather and for making ink. Knowledge of gall types increased during the late nineteenth century and throughout the twentieth century as more species were described and their structure became more clearly understood, and yet even today, little is known about the mechanisms that cause gall formation as well as the life cycles of the organisms that initiate gall growth. Since most galls do not cause any economic damage to crop plants, research funding has traditionally been sparse in this area. However, the insect cycles and gall structures are amazing examples of the complexity of nature. Margaret Redfern explores these fascinating complexities in this latest New Naturalist volume, providing much-needed insight into the variety of galls of different types caused by a wide range of organisms including fungi, insects and mites. She discusses the ecology of galls more generally and focuses on communities of organisms within galls, the evolution and distribution of galls, as well as human and historical perspectives."

Gardening can be frustratingly shrouded in secrecy. Fickle plants make seemingly spontaneous decisions to bloom or bust, seeds sprout magically in the blink of an eye, and deep-rooted mysteries unfold underground and out of sight. Understanding basic botany is like unlocking a horticultural code; fortunately learning a little science can reveal the secrets of the botanical universe and shed some light on what’s really going on in your garden. Practical Botany for Gardeners provides an elegant and accessible introduction to the world of botany. It presents the essentials that every gardener needs to know, connecting explanations of scientific facts with useful gardening tips. Flip to the roots section and you’ll not only learn how different types of roots support a plant but also find that adding fungi to soil aids growth. The pruning section both defines “lateral buds” and explains how far back on a shoot to cut in order to propagate them. The book breaks down key areas and terminology with easy-to-navigate chapters arranged by theme, such as plant types, plant parts, inner workings, and external factors. “Great Botanists” and “Botany in Action” boxes delve deeper into the fascinating byways of plant science. This multifaceted book also includes two hundred botanical illustrations and basic diagrams that hearken to the classic roots of botany. Part handbook, part reference, Practical Botany for Gardeners is a beautifully captivating read. It’s a must for garden lovers and backyard botanists who want to grow and nurture their own plant knowledge.

Temperate broadleaved trees grow in very different ecosystems in the northern and southern hemispheres, but are also found extensively in many tropical and subtropical mountain areas. A wide range of non-wood products are derived from temperate broadleaved trees, and their description is organized in this volume according to the part of the tree from which they are obtained (whole tree, foliage, flowers, etc.). This information is presented in order to raise awareness on, and assist in identifying, opportunities for the management and production of non-wood products from temperate broadleaved trees. The intended audience of this publication ranges from interest groups in the forest, agriculture and rural development sectors to conservation agencies in developed and developing countries.

Few settings in literature are as widely known or celebrated as J.R.R. Tolkien's Middle-Earth. The natural landscape plays a major role in nearly all of Tolkien's major works, and readers have come to view the geography of this fictional universe as integral to understanding and enjoying Tolkien's works. And in laying out this continent, Tolkien paid special attention to its plant life; in total, over 160 plants are explicitly mentioned and described as a part of Middle-Earth. Nearly all of these plants are real species, and many of the fictional plants are based on scientifically grounded botanic principles. In Flora of Middle Earth: Plants of Tolkien's Legendarium, botanist Walter Judd gives a detailed species account of every plant found in Tolkien's universe, complete with the etymology of the plant's name, a discussion of its significance within Tolkien's work, a description of the plant's distribution and ecology, and an original hand-drawn illustration by artist Graham Judd in the style of a woodcut print. Among the over three-thousand vascular plants Tolkien would have seen in the British Isles, the authors show why Tolkien may have selected certain plants for inclusion in his universe over others, in terms of their botanic properties and traditional uses. The clear, comprehensive alphabetical listing of each species, along with the visual identification key of the plant drawings, adds to the reader's understanding and appreciation of the Tolkien canon.

As well as examining successful biological control programmes this book analyses why the majority of attempts fail. Off-target and other negative effects of biological control are also dealt with. Chapters contributed by leading international researchers and practitioners in all areas of biological control afford the book a breadth of coverage and depth of analysis not possible with a single author volume. Combined with the use of other experts to review chapters and editorial oversight to ensure thematic integrity of the volume, this book provides the most authoritative analysis of biological control published. Key aspects addressed include how success may be measured, how successful biological control has been to date and how may it be made more successful in the future. With extensive use of contemporary examples, photographs, figures and tables this book will be invaluable to advanced undergraduate and postgraduate students as well as being a `must' for all involved in making biological control successful.

In an era when human lives are increasingly measured and weighed in relation to the medical and scientific, notions of what is “normal” have changed drastically. While it is no longer useful to think of a person’s particular race, gender, sexual orientation, or choice as “normal,” the concept continues to haunt us in other ways. In The End of Normal, Lennard J. Davis explores changing perceptions of body and mind in social, cultural, and political life as the twenty-first century unfolds. The book’s provocative essays mine the worlds of advertising, film, literature, and the visual arts as they consider issues of disability, depression, physician-assisted suicide, medical diagnosis, transgender, and other identities. Using contemporary discussions of biopower and biopolitics, Davis focuses on social and cultural production—particularly on issues around the different body and mind. The End of Normal seeks an analysis that works comfortably in the intersection between science, medicine, technology, and culture, and will appeal to those interested in cultural studies, bodily practices, disability, science and medical studies, feminist materialism, psychiatry, and psychology.
