tailieunhanh - Insect Diversity Conservation

Some say that ‘the cockroach’ will be the last species on Earth to survive. Then it has been calculated that one gravid aphid, left to reproduce with zero mortality, will, after one year, cover the globe with an aphid layer over 140 km thick. Not forgetting too, that flies and fleas vector disease. So, why should we even consider conserving insects? Quite simply, without insects, the likelihood is that the world as we know it would be radically changed in a matter of days. Besides, it is only a tiny minority of insects that harm our lives. These two faces of insects, friend and foe, are just. | Ilnsect Diversity conservation Michael . Samways 9 Cambridge CAMBRIDGE more information - 9780521783385 This page intentionally left blank Insect Diversity Conservation This groundbreaking book is an up-to-date global synthesis of the rapidly developing and important field of insect conservation biology. Insects are by far the most speciose organisms on earth yet barely known. They play important roles in terrestrial ecological processes and in maintaining the world as we know it. They therefore present particular conservation challenges especially as a quarter may well become extinct in the next few decades. This book first addresses the ethical foundation of insect conservation and asks why we should concern ourselves with conservation of a butterfly beetle or bug. The success of insects and their diversity which have survived the comings and goings of glaciers is now facing a more formidable obstacle the massive impact of humans. After addressing threats from invasive alien plants to global climate change the book then explores ways in which insects and their habitats are prioritized mapped monitored and conserved. Landscape and species approaches are considered. Restoration and the role of conventions and social issues are also discussed. The book is for undergraduates postgraduates researchers and managers both in conservation biology or entomology and in the wider biological and environmental sciences. MICHAEL J.
