Condición: 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. Condición: 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.…

Dragonflies are a beautiful, important and conspicuous component of freshwater, whether still or flowing. They are also important indicators of freshwater quality and condition, which is significant for current and future conservation initiatives in South Africa. The country s dragonflies are particularly interesting as many are special or endemic to the area, making it a part of the world of great conservation significance. Sadly however, many of these endemic species are highly threatened, especially by invasive alien trees which shade out their habitat. This book is about this exciting dragonfly fauna. Besides aiming at increasing awareness of these lovely and sensitive insects, it enables their identification, using several approaches, from simple flick-through to the use of comprehensive identification keys. Each species is also given a Dragonfly Biotic Index, covering a spectrum from the most common, widespread and tolerant species through to the most threatened, rare and sensitive ones. Sofia, Moscow.
