Available in PDF, EPUB and Kindle. Book excerpt: Optimising Pesticide Use brings together the wide range of scientific disciplines necessary to ensure best practice through monitoring what is used and improving how it is formulated and applied. The book provides: An in-depth exploration of pesticide optimisation from the view point of industry and research scientist A case study on the development of a new range of active chemistries from bacteria A discussion of complementary pest control methods This text will provide essential information to workers in the pesticide industry and regulatory community who need to be aware of current thinking and advancements in the optimal use of pesticidal compounds and systems, as well as environmental organisations and aid development organisations.

Download or read book New Toxicology for Old written by P.L. Chambers and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nervous system is in the most cases a likely target for the untoward effects of chemicals. The harmful consequences affect primarily the individual but may also considerably strain the whole society. The consumption of ethanol is a glaring example (National Institute on Alcohol Abuse and Alcoholism 1978). As ethanol, many organic liquids have similar immediate effects on the nervous system. The rapidity of the response suggests the involvement of the neuronal communication. The nervous system is also vulnerable to the depletion of oxygen, another common cause for the rapid deterioration of the brain function. It is quite impossible to list all the effects produced by the very large number of the individual chemicals. It would be more fruitful to try to understand the characteristics of the nervous system and the biochemical toxic mechanisms in the evaluation of the neurotoxicity of chemicals. Transfer of Xenobiotics in the Brain The adult central nervous system displays a functional barrier toward the blood-borne chemicals so that water-soluble compounds with an approximate molecular weight above 100 are largely prevented from directly entering the brain (Bradbury 1979). The functional barrier has morphological features typical to it and has a very close association of adjacent capillary cells separated by clefts of 12 A wide (Jacobs 1978). The nervous system capillaries are enveloped by glial cell tongues, and these pericytes contain contractile elements (Le Beux and Willemot 1978a, b) so that the capillaries can be constricted.

Download or read book Otters Ecology and Conservation written by C. F. Mason and published by Cambridge University Press. This book was released on 2009-02-12 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the European otter, describing its life history, including fresh information and providing details of survey methods and the state of populations throughout the range. Otters have decreased substantially in numbers and range during the present century through a combination of pollution, habitat destruction and direct persecution. The otter, at the top of the food chain, is a vulnerable animal in a vulnerable environment - the river - and can be seen as an indicator of a healthy environment; a good otter population indicates a properly functioning river ecosystem. The research of the authors highlights the fact that successful conservation of this familiar though elusive animal depends upon public education and sympathy as much as upon detailed ecological knowledge. This account will appeal to amateur naturalists, teachers of natural history and biological sciences and students of animal ecology and conservation. It also provides an important reference for professional conservationists and wildlife biologists.

Download or read book The Sparrowhawk written by Ian Newton and published by A&C Black. This book was released on 2010-11-30 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dr Newton is now a senior ornithologist with the Natural Environment Research Council and the book draws on his wide knowledge of the Sparrowhawk, as well as that of other workers in Britain and abroad. The text gives a detailed account of all aspects of the Sparrowhawk's lifestyle, population levels and trends, and the impact of man and environment on the species in recent times. The book also has the benefit of Dr Newton's particular interest in population regulation and breeding performance, and in the remarkable contrast in size between the Sparrowhawk sexes (males being half the weight of females), which means that they diverge, almost as separate species, in habitat preference, diet and in response to circumstance. The narrative is fully supported by diagrams, tables and photographs, and is embellished by Keith Brockie's evocative and accomplished drawings.

Book excerpt: This attractively illustrated book reviews the effects of agricultural development on bird populations in Britain. Examining modern farmland as a bird habitat, it explains the changes, both in habitat structure and in available resources, that have occurred as a result of mechanisation and use of agrochemicals. Farmland bird communities are described, and their composition related to farm structure and land use. Based extensively on empirical data extracted from the British Trust for Ornithology's Common Bird Census and from nest histories recorded in the BTO'S Nest Record Scheme, the book presents an important analysis of the position of agricultural bird populations under modern farming systems. Particular examination has been made of the impact of changing methods, rotations and crops, which have been underestimated in the past. Resulting from the co-operation between a professional ornithologist and a working cereal farmer, this book provides an objective and informed view of the impact of British agriculture on bird populations.
