Zustand: Fine. xii, 342, 104 line diagrams 30 half-tones 134 figures. 247x174mm. PB. Fine unmarked copy. This textbook addresses the ethical foundation of insect conservation, and asks why should we concern ourselves with conservation of a butterfly, beetle or bug? After addressing threats, from invasive alien plants to climate change, the book explores ways insects and their habitats are prioritised, mapped, monitored and conserved. Landscape and species approaches are considered. This book is for undergraduates, postgraduates, researchers and managers in conservation biology or entomology. [9780521789479].

Zustand: NEW. 600, . . PB. NEW. . A landmark, field-defining work by one of the founding fathers of this burgeoning discipline of conservation science. This book presents a state-of-the-art, comprehensive review of the entire field of insect conservation, from single-species conservation to whole-ecosystem approaches, and from natural ecosystems to the urban landscape.The variety and number of insects are truly vast. They are the most speciose group of organisms on Earth, with the majority barely known to science or still not described at all. They are a vital component in all terrestrial ecosystems, which would fail to function normally without them.Insect populations worldwide, however, are under threat. Human-mediated degradation of natural habitats, pollution, over-use of pesticides, and the spread of urbanization has led to the collapse of insect populations in many areas of the world. A growing recognition of the importance of insects in natural and agricultural systems has stimulated the development of an entire discipline dedicated to their conservation.This book is designed to be used by students of conservation biology and ecology, but also serves as an essential overview for professional entomologists with an interest in conservation, and for conservationists interested in insects. The book communicates on three levels: (i) through the text, with extensive references providing a gateway to the ever-increasing primary literature; (ii) through the extensive use of carefully constructed illustrations, with detailed captions which act to summarize the text and are complete in their own right; and (iii) through focused key points at the end of every chapter, which summarise the main learning points for students.

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - This book is a paperback reprint of a previously published hardback. Insects are the major component of the world's biodiversity. By virtue of their vast numbers of both species and individuals, they are vital determinants of terrestrial ecological processes. Quantiatively, insects are important pointers for species-rich geographical areas. Qualitatively, they are also important, whether the subjects of conservation themselves or as tools for identifying biotic areas with high endemism. Insect Conservation Biology covers a wide range of topics from single species to landscape conservation, and from rare butterflies to the benefits-and-risks of biocontrol agents. The approach is both positive and realistic, with insects being discussed in the contexts of sustainable development, agroecology and monitoring environmental change. Ethical issues surrounding insects are also considered as well as clear ecommendations for the future. Conservation circles have given too little attention to the ecological significance of insects, while entomologists have been engaged mostly in controlling a tiny minority of species of insect pests. The realms of conservationists and entomologists are brought together in this ground-breaking book.

Zustand: New. xiii, 539, col photos, col illus. . HB. NEW. . This is the first, comprehensive, modern text on the conservation of this iconic group of insects. Dragonflies are sensitive to the health of freshwater systems, and the quality of vegetation along rivers and around ponds. They are also excellent indicators in these times of great concern over the quality of our freshwater supplies. This book is for naturalists, citizen scientists, entomologists and conservation scientists, as well as practitioners and policy makers around the world. [9781789248371].
