Download or read book Medical Insects and Arachnids written by R.P. Lane and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 733 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surprising though it seems, the world faces almost as great a threat today from arthropod-borne diseases as it did in the heady days of the 1950s when global eradication of such diseases by eliminating their vectors with synthetic insecticides, particularly DDT, seemed a real possibility. Malaria, for example, still causes tremendous morbidity and mortality throughout the world, especially in Africa. Knowledge of the biology of insect and arachnid disease vectors is arguably more important now than it has ever been. Biological research directed at the development of better methods of control becomes even more important in the light of the partial failure of many control schemes that are based on insecticide- although not all is gloom, since basic biological studies have contributed enormously to the outstanding success of international control programmes such as the vast Onchocerciasis Control Programme in West Africa. It is a sine qua non for proper understanding of the epidemiology and successful vector control of any human disease transmitted by an arthropod that all concerned with the problem - medical entomologist, parasitologist, field technician - have a good basic understanding of the arthropod's biology. Knowledge will be needed not only of its direct relationship to any parasite or pathogen that it transmits but also of its structure, its life history and its behaviour - in short, its natural history. Above all, it will be necessary to be sure that it is correctly identified.

Book excerpt: TO ACCESS THE ARTWORK FROM THE BOOK, PLEASE VISITwww.blackwellpublishing.com/gullan. This established and popular textbook is the definitive guide tothe study of insects; a group of animals that represent over halfof the planet’s biological diversity. Completely updated and expanded, this new edition examines allaspects of insect biology including anatomy and physiology, ecologyand evolution of insects, insect behaviours such as sociality,predation, parasitism and defense, medical and veterinaryentomology and methods of collection, preserving and identifyinginsects. Features new chapters on the methods and results of studies ofinsect phylogeny and a new review of insect evolution andbiogeography. Includes expanded sections on species diversity, socialbehaviour, pest management, aquatic entomology, parasitology andmedical entomology. Successful strategies in insect conservation are also coveredfor the first time, reflecting the increasing threat to naturalecosystems from environmental changes. Boxes highlighting key themes, suggestions for further readingand illustrations, including specially commissioned drawings andcolour plates, are included throughout. The artwork from the text is available for instructors eithervia CD-ROM or by visiting www.blackwellpublishing.com/gullan.

This book was released on 2013-03-08 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: As human populations expand and have increasing access to technol ogy, two general environmental concerns have arisen. First, human pop ulations are having increasing impact on the earth system, such that we are altering the biospheric carbon pools, basic processes of elemental cycling and the climate system of the earth. Because of time lags and feedbacks, these processes are not easily reversed. These alterations are occurring now more rapidly than at any time in the last several million years. Secondly, human activities are causing changes in the earth's biota that lead to species extinctions at a rate and magnitude rivaling those of past geologic extinction events. Although environmental change is potentially reversible at some time scales, the loss of species is irrevo cable. Changes in diversity at other scales are also cause for concern. Habitat fragmentation and declines in population sizes alter genetic di versity. Loss or introduction of new functional groups, such as nitro gen fixers or rodents onto islands can strongly alter ecosystem processes. Changes in landscape diversity through habitat modification and frag mentation alter the nature of processes within and among vegetation patches. Although both ecological changes altering the earth system and the loss of biotic diversity have been major sources of concern in recent years, these concerns have been largely independent, with little concern for the environmental causes the ecosystem consequences of changes in biodiversity. These two processes are clearly interrelated. Changes in ecological systems cause changes in diversity.
Download or read book Tracking Environmental Change Using Lake Sediments written by John P. Smol and published by Springer Science & Business Media. This book was released on 2006-04-11 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: Paleolimnology is a rapidly developing science that is now being used to study a suite of environmental and ecological problems. This volume is the fourth handbook in the Developments in Paleoenvironmental Research book series. The first volume (Last & Smol, 2001a) examined the acquisition and archiving of sediment cores, chronological techniques, and large-scale basin analysis methods. Volume 2 (Last & Smol, 2001b) focused on physical and chemical methods. Volume 3 (Smol et al. , 2001), along with this book, summarize the many biological methods and techniques that are available to study long-term environmental changeusing information preserved in sedimentary profiles. A subsequent volume (Birks et al. , in preparation) will deal with statistical and data handling procedures. It is our intent that these books will provide sufficient detail and breadth to be useful handbooks for both seasoned practitioners as well as newcomers to the area of paleolimnology. These books will also hopefully be useful to non-paleolimnologists (e. g. , limnologists, archeologists, palynologists, geographers, geologists, etc. ) who continue to hear and read about pal- limnology, but have little chance to explore the vast and sometimes difficult to access journal-based reference material for this rapidly expanding field. Although the chapters in these volumes target mainly lacustrine settings, many of the techniques described can also be readily applied to fluvial, glacial, marine, estuarine, and peatland environments. This current volume focuses on zoological indicators preserved in lake sediments, whilst Volume 3 focused on terrestrial, algal, and siliceous indicators.

Download or read book The Natural History of Blackflies written by Roger W. Crosskey and published by . This book was released on 1990-11-28 with total page 742 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of blackflies has come of age--the blackfly is now recognized as a carrier of major endemic diseases; its larval stages are seen to play a major role in the ecology of rivers and streams; and blackfly chromosomes have proved unusually amenable material for cytogenetical studies. The expanded interest in the blackfly has greatly increased the scientific literature about them--literature that is extremely technical, highly specialized, and often of little help to non-specialists. This work bridges the gap between specialists and those whose work brings them in contact with the blackfly, but who need information at a more general level. It synthesizes present knowledge about the natural history of the fly family Simuliidae, covering taxonomic background, elements of larval structure and life in water, adult fly structure, migration, mating, biting and bloodsucking, human diseases, and natural enemies of larval and adult flies. Over 1200 bibliographic citations, a glossary of technical terms, and numerous figures, tables and illustrations are included.
