Despite their enormous bulk and complexity of architecture, plants make up only around a quarter of a million of the 8 million or so species on Earth. The major components of biodiversity, instead, are the smaller, largely unseen, silent majority of invertebrates â€{u0B6F}st of which are arthropods. Vertebrates, a mere blip on the biotic horizon, are elevated in importance in the bigger scheme of things only by the human psyche. This collection of more than 30 peer-reviewed papers focuses on the diversity and conservation of arthropods, whose species inhabit virtually every recess and plane â€{u086E}d feature somewhere in virtually every food web â€{u0BEE} the planet. Highlighting issues ranging from large-scale disturbance to local management, and from spatial heterogeneity to temporal patterns, these papers reflect some of the most exciting new research taking place today â€{u086E}d in some of the most biodiverse corners of the planet. Edited by David Hawksworth and Alan Bull, with a preface by Michael J Samways, this book will provide a valuable reference to anyone interested in the diversity and conservation of arthropods.
