Bound in the original blue pictorial wraps. From the rear cover: "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 recommendations 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.". First Paperback Edition. Softcover. Fine condition.

Octavo,297 pp.,colour photographs, fine copy in softcover. Pensoft Series Faunistica, No. 70. 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. Michael Samways is Professor and Chair of the Department of Conservation Ecology and Entomology, Stellenbosch University., He is a Fellow of the Royal Society of South Africa and a Fellow of the University of KwaZulu-Natal. He has published 260 scientific papers and written several books on insect biology and conservation, the most recent of which is Insect Diversity Conservation, Cambridge University Press. He has won several awards, and in the last two years, these include the Stellenbosch University Rector's Award for Research Excellence, the John Herschel Medal from the Royal Society of South Africa, and the Senior Captain Scott Medal from the South African Academy for Science and Art. Michael is on several international editorial boards and involved with various international committees devoted to invertebrate conservation. Indeed, his research team is dedicated to the conservation of invertebrates and other biodiversity, which so enrich our planet.…

Paperback. Condizione: new. Paperback. Dragonflies are among the most familiar and popular of all insects, deeply embedded in human cultural history. They are iconic and tell us much about the environments in which we and they live. Their conservation is an important part of biodiversity conservation. One modern dragonfly species is listed as extinct, with many others currently threatened. It is now essential to increase conservation efforts towards saving these threatened species, with strategies now available for doing this. Recovery of dragonfly populations goes hand in hand with improvements to both freshwater conditions and bank vegetation quality. In contrast, some other dragonfly species have benefitted greatly from human transformation of the landscape, with artificial ponds in particular, increasing the population levels of many species. In turn, climate change is seeing many geographical range shifts. Dragonflies are variously sensitive to the health of freshwater systems, and the quality of vegetation along rivers and around ponds. Dragonflies are excellent indicators in these times of great concern over the quality of our freshwater supplies. Their wide range of sensitivities enables us to measure the extent to which freshwater ecosystems are either deteriorating or are improving when we undertake restoration. They enable us to gauge how well we are conserving freshwaters, whether ponds and lakes, streams or rivers. They are also good umbrellas for many other freshwater inhabitants, which altogether reflect the health of a freshwater system. Conservation of Dragonflies: Sentinels for Freshwater Conservation is for naturalists, citizen scientists, entomologists and conservation scientists, as well as practitioners and policy makers around the world. This is the first, comprehensive text on the conservation of this iconic group of insects. Dragonflies are indicators of the health of freshwater systems, and the quality of vegetation along rivers and around ponds.
