• First title in Stackpole Books' new Wild Guide series • A complete, expert introduction to the world of dragonflies and also covers damselflies • Detailed color drawings of different species and behaviors Dazzling in appearance, idiosyncratic in behavior, dragonflies and damselflies have long captured the imaginations of nature lovers. In this illustrated natural history guide, Cynthia Berger takes the reader on a whirlwind trip through the lives of these intriguing insects, from their birth underwater (where they actually spend most of their lives as ferocious nymphs) to their miraculous transformation into free-flying adults. Features a field guide to the most common North American species--including life-size silhouettes for easy identification--as well as tips for observing dragonflies in the wild and attracting them to your backyard.
This book provides a critical summary of the major advances in insect ecology and evolution, discussing the advantages of using dragonflies as model organisms for studies in such areas.
This is the only book written in English to cover the entire European fauna, comprising 124 species of resident damselfly (Zygoptera) and dragonfly (Anisoptera), illustrated on the 30 plates of 219 colour figures. In most cases, both sexes as well as important variants are depicted, all enlarged. In his Foreword to this revised edition, Professor Philip Corbet, Past-President of the Worldwide Dragonfly Association and doyen of British odonatists, states that, as a standard reference work, “it will continue to contribute importantly to the progress of odonatology.” The author has made a few corrections to his original text, which covered 114 species of Odonata breeding in Europe, and has added a new Preface and an updating Supplement. The Introduction, which is largely unchanged, includes chapters on History; Life History; the Adult Dragonfly; Distribution; Morphology of the Adult Dragonfly; a complete, updated Check List; and Keys to the suborders and families. The Systematic section gives keys to the genera and species, with clear descriptions and details of the biology, flight periods, and distribution of all species found in Europe, with distribution maps showing national boundaries. This is now followed by the Supplement, in which Dr Askew has added a further ten resident species, including one new to science, and several adventives. It also provides new information under the following headings: Nomenclature; Orthography; Thermoregulation; American species observed in Europe; Accidental Introductions into Europe; Other species newly recognized in Europe; Species new to the British Isles; Expansion of recorded ranges within Europe; Other new distribution records; and Contraction of recorded ranges. The author goes on to list major European and national literature on the Odonata published since 1988. There are numerous line-drawings throughout the text and over 100 new references to the European literature have been added to the supplement bringing the total to over 650. The book concludes with a new Index to English and scientific names, incorporating all species, subspecies and synonyms cited in the revised text. There are two plates of colour photographs showing biology and habitats and the author has added a further colour plate to his original 29 plates of adult insects, depicting five of the new European species and one from North America. In its new, slightly-reduced, softback format, this classic work, which has already sold 3000 copies, will be more practical in the field and should prove extremely popular with British and Continental odonatists.
Primary sexual traits, those structures and processes directly involved in reproduction, are some of the most diverse, specialized, and bizarre in the animal kingdom. Moreover, reproductive traits are often species-specific, suggesting that they evolved very rapidly. This diversity, long the province of taxonomists, has recently attracted broader interest from evolutionary biologists, especially those interested in sexual selection and the evolution of reproductive strategies.Primary sexual characters were long assumed to be the product of natural selection, exclusively. A recent alternative suggests that sexual selection explains much of the diversity of "primary" sexual characters. A third approach to the evolution of reproductive interactions after copulation or insemination has been to consider the process one of sexual conflict. That is, the reproductive processes of a species may reflect, as does the mating system, evolution acting on males and on females, but in different directions.In this volume, authors explore a wide variety of primary sexual characters and selective pressures that have shaped them, from natural selection for offspring survival to species-isolating mechanisms, sperm competition, cryptic female choice and sexual arms races. Exploring diverse reproductive adaptations from a theoretical and practical perspective, The Evolution of Primary Sexual Characters will provide an unparalleled overview of sexual diversity in many taxa and an introduction to the issues in sexual selection that are changing our view of sexual processes.
Splendidly illustrated from nature, this encyclopedia describes with rigour and grace some of the most complex and bizarre behaviours in the animal world.
The Eastern Mediterranean region supports just over 4.4% of the global human population yet contains only 1.1% of its renewable water resources, which are under constant threat from the impacts of unsustainable water withdrawal, dam development and climate change. This IUCN report and accompanying dataset represents a major advance in the provision of information to help incorporate biodiversity needs into water development planning processes within an Integrated River Basin Management framework. This volume includes species information compiled for each river and lake sub-basin and incorporates information from the assessment conducted by IUCN's Global Species Programme, in collaboration with its partners, of the status and distribution of all described species of freshwater fishes, molluscs, odonates, and plants from across the Eastern Mediterranean with existing information for species of freshwater dependent amphibians, birds, crustaceans, and mammals. This work represents the most comprehensive assessment yet of freshwater biodiversity at the species level for this part of the world.
