This book was released on 2007-01-25 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 – and feature in virtually every food web – on the planet. Highlighting issues ranging from large-scale disturbance to local management, from spatial heterogeneity to temporal patterns, these papers reflect exciting new research – and take the reader to some of the most biodiverse corners of the planet.
Download or read book Field Guide for the Biological Control of Weeds in the Northwest written by Rachel Winston and published by Government Printing Office. This book was released on 2017-12-13 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: This guide focuses on the most problematic weeds in eastern North America for which there are at least some biocontrol agents established and/or available. Multiple photos and descriptions of each weed included in this guide emphasize key identification traits and plant ecology. For each weed included in this guide, all biocontrol agents released or currently found in North America are described individually. Photos highlighting key identification features and damage are included. The release history, current status, and recommended use of each biocontrol agent are described in detail. Recommendations and current impact often vary between the US and Canada, therefore, the information is presented separately. Includes international code of best practices for classical biological control of weeds.
Download or read book The Economic Importance of Insects written by Dennis S. Hill and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last few decades there has been an ever-increasing component in most BSc Zoology degree courses of cell biology, physiology and genetics, for spectacular developments have taken place in these fields. Some aspects of biotechnology are now also being included. In order to accommodate the new material, the old zoology courses were altered and the traditional two-year basis of systematics of the animal kingdom, comparative anatomy (and physiology) and evolution, was either severely trimmed or reduced and presented in an abridged form under another title. Soon after these course alterations came the swing to modular teaching in the form of a series of shorter, separate courses, some of which were optional. The entire BSc degree course took on a different appearance and several different basic themes became possible. One major result was that in the great majority of cases taxonomy and systematics were no longer taught and biology students graduated without this basic training. We field biologists did appreciate the rising interest in ecology and environ mental studies, but at the same time lamented the shortage of taxonomic skills, so that often field work was based on incorrect identifications. For years many of us with taxonomic inclinations have been bedevilled by the problem of teaching systematics to undergraduates. At a guess, maybe only 5% of students find systematics interesting. It is, however, the very basis of all studies in biology - the correct identification of the organism concerned and its relationships to others in the community.
Download or read book Urban Insects and Arachnids written by William H. Robinson and published by Cambridge University Press. This book was released on 2005-04-14 with total page 538 pages. Available in PDF, EPUB and Kindle. Book excerpt: This account provides the first comprehensive coverage of the insect and other arthropod pests in the urban environment worldwide. Presented is a brief description, biology, and detailed information on the development, habits, and distribution of urban and public health pests. There are 570 illustrations to accompany some of the major pest species. The format is designed to serve as a ready-reference and to provide basic information on orders, families, and species. The species coverage is international and based on distribution in domestic and peridomestic habitats. The references are extensive and international, and cover key papers on species and groups. The introductory chapters overview the urban ecosystem and its key ecological components, and a review of the pests status and modern control strategies. The book will serve as a professional training manual, and handbook for the pest control professionals, regulatory officials, and urban entomologists. It is organized alphabetically throughout.
Download or read book Pests of Crops in Warmer Climates and Their Control written by Dennis S. Hill and published by Springer Science & Business Media. This book was released on 2008-07-16 with total page 708 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a textbook providing basic data about the crop pests and the damage they inflict throughout the tropics and sub-tropics. Each major pest is illustrated by either a line drawing or a photograph, and sometimes the damage can also be seen. A world distribution map is provided for each species. Control measures tend to be general rather than very specific. Most of the pests are insects and mites, but some nematodes, molluscs, birds and mammals are included.
Download or read book Pests of Stored Foodstuffs and their Control written by Dennis S. Hill and published by Springer Science & Business Media. This book was released on 2007-05-08 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is intended to serve as an introduction to the pests of stored foodstuffs of all types on a worldwide basis, and as a broad reference text. It is aimed at being complementary to the more detailed and more specific texts that are listed in the References. It does presuppose an adequate basic knowledge of entomology and zoology in the user. The stored products mentioned in the text are commercial products in the widest sense, including all types of plant and animal materials in addition to grain and prepared foodstuffs. Storage is viewed very broadly, from one day on a shelf to several years in a silo, or refrigerated store at -20°C. In many publications the produce surveyed has been restricted to stored grains, because of their obvious importance to human society, and because of the great quantities involved. For many different materials, of both plant and animal origin, there is a shortage of specific information, but it is to be hoped that this situation will gradually be rectified. It should be clearly understood that any reference to animal pests is made in the strict zoological sense, and refers to any members of the Kingdom Animalia. There is a regrettable tendency in some circles to use the term ‘animal’ as being synonymous with ‘mammal’ – a habit to be deplored! There is definite emphasis on animal pests in this text, but micro-organisms are included where relevant.
