Temperate Forage Legumes
by J Frame. Edited by J F L Charlton, A S Laidlaw.
The major temperate forage legumes are of global importance in the sustainable productivity of ruminant feed in the developed world. This book brings together in one volume all aspects of their basic biology and associated production practices. Emphasis is placed on the importance of understanding plant characteristics and their consequences in terms of forage output, quality and utilization by livestock. Recent research advances are reviewed and put into context and several recently commercialised species are also covered. The introduction considers the history, current extent, benefits and limits of temperate forage legume usage. Subsequent chapters are dedicated to a comprehensive examination of each forage species in turn, dealing with their origin, morphology, physiology, ecology, nitrogen-fixing capability, cultivars, seed production, nutritive value and productivity. The key factors for optimal management are identified and the prospects for the future outlined, including the potential arising from the use of biotechnology. This book is essential reading for degree and postgraduate students of plant science, agronomy and animal production. Additionally, students and researchers in ecology and environmental science will also find it a valuable resource. The management sections will be of particular value to grassland advisers, consultants and progressive land users.

Einführung in die Kybernetik
Aus dem Englischen von Jörg Adrian Huber
by W. Ross Ashby, Jörg Adrian Huber, W. L. Bauer, Jörg Adrian Huber
Die »Einführung in die Kybernetik« ist eines der Standardwerke der jungen Wissenschaft Kybernetik, nicht zuletzt durch des Autors didaktisches Geschick der Grundlagenvermittlung. Ashby vermeidet es, für den Laien unnötig verwirrende Bereiche der Elektronik und der höheren Mathematik in seine Einführung einzubeziehen und verwendet satt dessen allgemeinverständliche Beispiele aus dem Alltag. Im ersten Teil geht es um Systeme im allgemeinen, um ihre schematische Darstellung durch Transformation, um Stabilität, Unabhängigkeit und Rückkoppelung. Im zweiten Teil des Buches befaßt sich Ashby mit »Information« im Zusammenhang mit der grundlegenden Theorie Shannons. Zur Erläuterung von Information und Codierung etc. werden zahlreiche Beispiele aus dem Bereich biologischer Forschung herangezogen. Der dritte Teil zeigt Verwendungsmöglichkeiten von Mechanismen und Information für die Regelung und Kontrolle von Systemen. Dabei geht es ebenso um natürliche Systeme (wie das menschliche Hirn), die Gegenstand der Physiologie sind, wie auch um künstliche, das heißt um die Konstruktion von Maschinen, die in ihrer Funktion der des Hirns vergleichbar sind.

Forest Dynamics in Heavily Polluted Regions
by Edited by John L Innes, J Oleksyn
Air pollution has been recognised as a potential problem for forests for nearly 150 years. Today, sulphur dioxide, fluorides, heavy metals and ozone are a significant problem, usually from large scale sources in industrial and urban areas. Problems are exacerbated in those regions where there is a poor understanding of the factors involved in forest decline and destruction and no rigorous control over it has been established.This book is the first report from the International Union of Forest Research Organization’s (IUFRO) Task Force on Environmental Change and provides an assessment of the extent of air pollution impacts on forests in heavily polluted regions. It includes case studies from Russia, Ontario (Canada), California and the Mediterranean region.It is also the first volume in a new book series covering many areas of forestry research, published by CABI Publishing in association with IUFRO.
