Book Description
The Mississippi Western Five Area Assessment, part of a series of statewide regional assessments, examines 1,630 square miles, falling within portions of seven Illinois counties in western Illinois-- Henderson, Henry, Knox, Mercer, Warren, as well as very small parts of Hancock and Rock Island counties and also falls within the physiographic region called Galesburg Till Plain. The report provides information on the natural and human resources of the area as a basis for managing and improving its ecosystems. The development of ecosystem-based information and management programs in Illinois are the result of three processes-- the Critical Trends Assessment Program, Conservation Congress, and Water Resources and Land Use Priorities Task Force.

Book Description
At the First International Symposium on Aquatic Oligochaete Biology in Sidney, B. C. , the suggestion was made to hold the second in Pallanza, on Lake Maggiore, at the C. N. R. -Istituto Italiano di Idrobiologia. At the same time it was decided that there should be a symposium every third year. The organization of the symposium was made considerably easier by the Senior Editor's having been in personal contact with several Russian colleagues (courtesy of a kind invitation from the U. S. S. R. Academy of Sciences), the 'Hamburg Group' and the Junior Editor. Correspondence with various students of Oligochaeta also furnished many useful suggestions. The Second International Symposium on Aquatic Oligochaete Biology was therefore held in Pallanza in late September 1982 and was attended by 53 scientists from 16 countries in Europe, North America, Asia and Australia. No review papers were formally invited as this had already been done at the first symposium: all the papers were accordingly allotted the same time for oral presentation. These proceedings contain all papers Hrabe and Slepukhina, which were given in absentia, as it presented at the symposium, including those by was impossible for the authors to join the group. The main topics were taxonomy and evolution of Oligo chaeta, life-cyle and population studies, the role of Oligo chaeta in assessing water pollution, physiolog ical studies, community and distribution studies. Special taxonomic workshops took place in the evenings.

Book Description
This book reviews the latest developments concerning the analysis, fate, behaviour and toxicity of pyrethroid insecticides. Over the last few decades, pyrethroid insecticides have increasingly replaced organochlorine pesticides due to their relatively lower mammalian toxicity, selective insecticide activity and lower environmental persistence. They represent 25% of global sales of insecticides, and are considered to be “safe” since they are converted to non-toxic metabolites by oxidative metabolism in fish and by hydrolysis in mammals. However, recent studies have demonstrated their environmental ubiquity, their bioaccumulation and their toxicity in various aquatic and terrestrial organisms, and even in humans. Featuring contributions by leading experts, the book discusses the physico-chemical properties and uses of pyrethroid insecticides; the latest chemical analytical methods; their occurrence in the environment, biota and food; and their isomeric and enantiomeric behaviour. It particularly highlights the toxicological effects and human exposure to pyrethroid insecticides, and also offers insights into the effects of the salmon industry on the marine environment with a case study of sea lice treatment using pyrethroids. This comprehensive book is a valuable source of information for environmental scientists, policymakers and producers interested in issues related to pyrethroid insecticides.

Book Description
The twelfth-century French poet Chrétien de Troyes is a major figure in European literature. His courtly romances fathered the Arthurian tradition and influenced countless other poets in England as well as on the continent. Yet because of the difficulty of capturing his swift-moving style in translation, English-speaking audiences are largely unfamiliar with the pleasures of reading his poems. Now, for the first time, an experienced translator of medieval verse who is himself a poet provides a translation of Chrétien’s major poem, Yvain, in verse that fully and satisfyingly captures the movement, the sense, and the spirit of the Old French original. Yvain is a courtly romance with a moral tenor; it is ironic and sometimes bawdy; the poetry is crisp and vivid. In addition, the psychological and the socio-historical perceptions of the poem are of profound literary and historical importance, for it evokes the emotions and the values of a flourishing, vibrant medieval past.
