Book Description
This book is based on Herbert Buhr's seminal keys of 1964-1965 (Bestimmungstabellen der Gallen (Zoo- und Phytocecidien) an Pflanzen Mittel- und Nordeuropas) and augmented with Houard's 1908-1913 work on Southern Europe (Les Zoocécidies des Plantes d'Europe et du Bassin de la Méditerranée). The authors have updated this with the research of a new generation of cecidologists, significantly expanding our knowledge of plant galls and their distribution. The 9,000 galls and malformations described by Buhr and Houard have been updated and 1,250 new galls described in more recent literature have been added. The nomenclature of both gall inducers and host plants has been updated, information about specific groups of gall inducers has been reviewed, and new insights have been added by a team of specialists. Moreover, they collected distribution data for the whole of Europe and, where available, adjacent areas.

Book Description
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

Book Description
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."

Book Description
A photographic guide to 536 species of plant galls found west of the Rockies Beautiful and bizarre, plant galls are growths of various shapes, sizes, and colors produced in response to invading organisms. Describing 536 species of galls and their causative agents, Plant Galls of the Western United States explores this unique realm with stunning photos and fascinating information about the life cycles of the organisms involved. Often species-specific, plant galls can be shaped like stars, baskets, clubs, wigs, bowls, and cups, with colors and combinations that stagger the imagination. This richly illustrated field guide examines how galls develop, and their uses, seasonal appearance and growth rate, predators, and defense mechanisms. The “architects” of galls—bacteria, fungi, mites, moths, beetles, flies, midges, and wasps—are explored in depth, and descriptions are paired with illustrations of these gall-inducing organisms and their typical galls. Gall accounts are divided into those that occur on trees, shrubs, and miscellaneous hosts, including native and ornamental plants. The guide contains a useful glossary and a bibliography. Features 536 gall species—including 120 new to science and 232 that have never appeared in a field guide before Examines for the first time more than 90 species from southwestern oak trees Contains more than 150 species from most of the deserts of the western states

Book Description
Grasslands are an important element of European nature. About half of Europe's endemic species depend on grasslands, whether in mountains, lowlands, river plains or coastal areas. Many grasslands originate in traditional agricultural landscapes. Modern intensification, however, brings many of these ecosystems under threat. 'Grasslands in Europe' is a tribute to these important ecosystems. It was written by an international team of grassland experts, who describe twenty-four case studies from countries in all of Europe - ranging from the grasslands of Gotland and #land (Sweden) to the Spanish Dehesa, and from the hay meadows of the British Pennine Dales to the steppes of Turkish Anatolia. Together, these case studies provide a fascinating glimpse into the various European grasslands, their value for nature, culture and agriculture, and the threats they are facing today. The accessible text as well as the rich illustrations will appeal to a wide audience. Grasslands in Europe contains a large number of stunning full-colour photographs of grassland landscapes, species and cultural history. It also contains many maps and infographics. Thematic chapters provide essential background information on topics such as grassland fauna, the history of agriculture, grassland communities, and the connection between grasslands and climate. The book also analyses the opportunities and risks of EU policy to conserve these grasslands. It offers a farmer-centred outlook to manage and to maintain the European grasslands of high nature value.

Book Description
The botanical history of Britain and North West Europe has a dark and a light side. Plants have been used as weapons to harm people, taken deliberately as addictive drugs and also employed as tools in witchcraft and used as magical amulets. Yet many of these same plants have been medicinally vital to numerous European communities; as the author notes, frequently the only difference between a benevolent medicine and a poison is dosage. In this book, which is richly illustrated with modern colour photographs and illustrations from herbals, Robert Bevan-Jones brings together a wealth of documentary and archaeo-botanical sources to discuss the cultural, social (and anti-social) role of the fifty most significant species of poisonous plants and fungi found in Britain, either as natives or as introductions. An introductory essay puts into context the development of British society's knowledge of toxic plants: the 'cultural botany' applied in Britain today has evolved over thousands of years, absorbing information from European texts and importing useful plants from Europe, such as the mandrake. The book's central A to Z section - from aconite to yew - then informs the reader about the history and uses of 43 species of poisonous plants, especially those that have a documented history of medicinal usage. Four important fungi species - death cap, liberty cap, fly agaric and ergot - also have separate essays. As well as the plants' histories and appearance, their chemical constituents receive coverage; these give them powerful and diverse properties, which demand our admiration and respect. The book aims to add to the knowledge offered by field identification guides, and help reduce the risk associated with accidental ingestion. Case histories are given in as much detail as possible and the information will hopefully help the reader understand the properties of plants they may encounter, either in an archaeological, botanical or horticultural context. Most of these plants can yet be found growing in woodlands, parks, botanical gardens, roadsides, waterways, churchyards and abbey sites. This is an essential book not only for botanists and historical ecologists, but also for anyone interested in the toxic plant traditions of Britain and Europe.

Book Description
The European families of the Diptera presents an identification key and family descriptions of all 132 families of Diptera (midges, mosquitoes, gnats, true flies) occurring in Europe. It is written by a well-known Dutch specialist, in collaboration with over 30 European dipterists. For the extensive identification key a new combination of important characters is employed, enabling relatively easy identification of families which are aberrant or traditionally considered difficult to identify. Over 600 line drawings are included to illustrate characters and families. Apart from the key, the book includes an extensive chapter on terminology. Information on systematics and the number of genera and species in Europe, a survey of the main characters, a summary of the biology and of the pertaining identification literature is included for all families. Due to its design and content, the book will be of interest to the lay public and the serious amateur alike.
