Natural Resource Management in Agriculture
Methods for Assessing Economic and Environmental Impacts
by Edited by Bekele Shiferaw, H A Freeman, Scott M Swinton
In response to increasing concerns about the degradation of natural resources and the sustainability of agriculture, many research programmes have been established in natural resource management (NRM). However, although methods for evaluating the impacts of crop improvement technologies are well developed, there is a dearth of methods for evaluating the impacts of NRM interventions. This is partly due to the complexity of interactions among natural resources, spatial and temporal dimensions of impact, and the valuation of direct and indirect environmental costs and benefits. This book discusses the unique features and methodological difficulties of NRM impact assessment. It examines the strengths and weaknesses of various impact assessment approaches, including econometric, bio-economic, and more direct methods. It also assesses and identifies data requirements for developing impact indicators and recommends suitable methodologies for assessing the impacts of NRM technologies on issues such as soil and water conservation and watershed and biodiversity management.

Evaluating Indirect Ecological Effects of Biological Control
by Edited by Eric Wajnberg, John K Scott, Paul C Quimby
A major concern for biological control has always been the risk of indirect unwanted effects on the ecology of other organisms. Our understanding of the ecological and evolutionary processes underlying these effects has until now been limited and experimental methods sometimes lacking. This book presents the key papers from of the first International Organisation for Biological Control global symposium, held in Montpellier, France, in October 1999. It addresses the issues and concerns involved in biological control, and assesses the current status of evaluation of the ecological effects.

The Best of H. C. Artmann
by H. C. Artmann, Klaus Reichert
Von allen deutschen Autoren, die nach 1945 zu schreiben begannen, ist Artmann ohne jeden Zweifel der vielseitigste, originellste und erfinderischste. So wie Artmann in fast allen Gattungen gearbeitet hat, auch den angeblich antiquierten, und ohne sich um die Tagesparolen der mal reine Dichtung betreibenden, mal engagierten, mal die Literatur totsagenden Kollegen zu kümmern, so hat er seine Quellen, seine Herkunft überall: in der Artusepik, in barocker Schäferpoesie, in den Wörterbüchern und Grammatiken von gut zwei Dutzend Sprachen, in Irland und im England des Sherlock Holmes, bei Villon und dem Wiener Vorstadtdialekt, Lorca, Gomez de la Serna, den Surrealisten und Dadaisten, in den Detektivheftchen der 20er Jahre und den Comic strips von damals bis heute. Unsere Auswahl versucht, nicht nur einen repräsentativen Querschnitt durch das Werk Artmanns zu geben, sondern gleichzeitig Verstreutes, an entlegensten Orten Publiziertes zu sammeln.

Quarantine Pests for Europe
by Mark Holderness, Edited by D G McNamara, I M Smith, Peter R Scott.
Data sheets on quarantine pests for the European Union and for the European and Mediterranean Plant Protection Organization. This book is the result of collaboration between EPPO and CAB INTERNATIONAL, sponsored by the Commission of the European Union, to prepare data sheets on pests of plants of quarantine significance for Europe and the Mediterranean region. Coverage extends to insects, mites, fungi, bacteria, viruses, nematodes and parasitic plants. It includes organisms that are found outside Europe and the Mediterranean that present a risk to this region, as well as those that are present but have restricted distribution and are subject to phytosanitary controls. The format of the FAO model data sheet is followed, using standard headings: identity, hosts, geographical distribution, biology, detection and identification, means of movement and dispersal, pest significance (including economic impact, control and phytosanitary risk), phytosanitary measures, and bibliography. The first edition of this book was published in December 1992 and consisted of 188 data sheets, some covering groups of similar organisms. During the intervening four years pests have been added to the EU and EPPO lists and changes have occurred in host range, geographical distribution, taxonomy and pest status of many of the organisms described. All data sheets have therefore been revised, some data sheets covering groups of similar organisms have been split up and 56 new sheets added, resulting in a total of 300 data sheets. The second edition will continue therefore to represent a definitive reference source, not only for those with specific interests in plant quarantine, but also for all concerned with pest management.

Biotechnology of Ornamental Plants
by Edited by R L Geneve, John E Preece, Scott A Merkle
Ornamental plants include herbaceous plants produced as bedding plants, greenhouse pot plants and cut flowers, as well as bulbs, trees, shrubs and vines. Ornamental plant production is of major and increasing importance worldwide. Basic scientific research in recent years has provided a better understanding of plant regeneration, genetics, growth and development. This has led to the development of technologies which can significantly improve ornamental species. This book reviews recent advances in the biotechnology of ornamentals. For example, genes have recently been identified for flower characteristics and pest resistance and these have been engineered into ornamental species. The book is divided into four main parts and is written by authors from the USA, UK, Canada, Netherlands, Australia and New Zealand. It is aimed primarily at workers in horticulture and plant biotechnology, but will also be of interest to plant physiologists, geneticists and molecular biologists.

Physiology of Vegetable Crops
by Fred J Muehlbauer, James L Brewster, Mary M Peet. Edited by H C Wien.
Many vegetable crops represent high value products and so it is essential to have a clear understanding of the physiology that lies behind successful production, as this enables the crop to be managed in the most effective way. The first section of the book takes a general look at the key stages during the growth of a plant, such as germination, transplanting and flowering and also looks at what can influence those stages. The second section is a detailed consideration of each of the major crops. Each chapter discusses the physiological aspects of vegetative growth, the induction of the reproductive structure, reproductive growth, senescence and any physiological disorders. Leading workers from the USA and Europe are brought together in one volume to produce a unique reference work for all advanced students of horticulture and crop production. This book is also an important resource for all research workers and teachers concerned with plant physiology.

Temperature Adaptation in a Changing Climate
Nature at Risk
by Edited by Kenneth B Storey, Karen K Tanino.
Temperature adaptation is a much neglected field in the minds of climate change researchers and policy makers. However, increasing fluctuations in temperature mean that the risk of cold and heat stress will pose an increasing threat to both wild and cultivated plants and animals, with frost injury expected to cause devastating damage to crops on an increasingly large scale. Thus, improving shared knowledge of the biological mechanisms of temperature adaptation in plants and animals will help prevent major losses of crops and genetic resources in the future.
