Experimental Design and Analysis for Tree Improvement provides a set of practical procedures to follow when planning, designing and analysing tree improvement trials. Using many fully-worked examples, it outlines how to: design field, glasshouse and laboratory trials; efficiently collect data and construct electronic data files; pre-process data, screening for data quality and outliers; analyse data from single and across-site trials using either GenStat or SAS; and interpret the results from statistical analyses. The authors address the many practical issues often faced in forest tree improvement trials and describe techniques that will give conclusive results with the minimum expense. The techniques provided are applicable to the improvement of not only trees, but to crops in general. Building on the success of the first edition, this new edition has been fully revised and updated to relate to the latest commercially-available software packages for design generation (CycDesigN) and data pre-processing and automated generation of programs for statistical analysis (DataPlus). For analysis, it now provides both GenStat and SAS programs as generated by DataPlus.

This text for scientists involved in the forestry field and glasshouse trials originated from a series of two week courses given in China on behalf of the Australian Centre for International Agricultural Research. Discusses the preparation, design, analysis and interpretation of forestry trials and introduces relevant statistical methodology and computing techniques, including GENSTAT programs for statistical analysis, ALPHA+ for the design and randomisation of trials, and DATACHAIN for the collection and preprocessing of data. Although aimed primarily at those involved in forest research, the techniques described are applicable to crops in general. Includes references and an index.

Die Verfahrensbibliothek Versuchsplanung und -auswertung ist eine umfangreiche Sammlung von fast 500 modernen und klassischen statistischen Methoden auf rund 2000 Seiten an deren Erarbeitung über 60 Wissenschaftler aus drei Erdteilen mitgewirkt haben. Neben rein methodischen Verfahren, in denen Tests, Konfidenz- und Punktschätzungen bzw. Regressions- und Varianzanalysen beschrieben werden, findet man auch viele spezielle Anwendungen wie klinische und epidemiologische Studien, räumliche Statistik, Lebensdauerprobleme, Human- und Populationsgenetik und Feldversuchswesen. Ein Verfahren beginnt mit der Beschreibung der Problemstellung, die aus den Teilen Planung (das bedeutet oft die Frage nach dem Versuchsumfang) und Auswertung besteht. Darauf folgt der aus den gleichen Teilen bestehende Lösungsweg sowie ein durchgerechnetes Beispiel. Der Verzicht auf Beweise macht die Verfahren leicht lesbar, die Beispiele erleichtern das Verständnis auch für Leser mit geringen Vorkenntnissen. Die Daten des Beispiels und das SAS-Programm können im jeweiligen Verfahren aufgerufen werden. Das Werk ist eine statistische Verfahrenssammlung zur Unterstützung experimenteller Forschungsarbeiten für höchste Ansprüche, insbesondere für klinische Studien, epidemiologische Studien, Geostatistik, Biometrie und landwirtschaftliches Versuchswesen. Das Werk wendet sich an Forscher aller Bereiche, die in ihrer Arbeit Versuche durchführen müssen.

In nature, radiata pine is very localised and an obscure tree species despite the romantic character of much of its natural habitat. That obscure status and the lack of any reputation as a virgin timber slowed its due recognition as a commercial crop. Nevertheless, it has become a major plantation forest crop internationally. It has become the pre-eminent commercial forest species in New Zealand, Chile and Australia, with important plantings in some other countries. It consequently features prominently in the international trade in forest products, in addition to its importance in domestic markets of grower countries. Very fast growth, considerable site tolerances, ease of raising in nurseries and transplanting, and ease of processing and using its wood for a range of products and purposes, have made it the utility softwood of choice almost everywhere it can be grown satisfactorily. Abundant genetic variation and its amenability to other management inputs created special opportunities for its domestication. The story of its domestication forms a classic case history in the development of modern commercial forestry, with trailblazing in both genetic improvement and plantation management; this inevitably meant a learning process that provided instructive lessons, especially for tree breeders dealing with some other species. Paradoxically, the plantation monocultures have played and can continue to play an important role in protecting natural forests and other forms of biodiversity. Given the attractions of growing radiata pine, there were inevitably cases of overreach in planting it, with lessons to be learnt. Economic globalisation has meant globalisation of pests and disease organisms, and the scale on which radiata pine is grown has meant is has been the focus of various biotic alarms, none of which have proved catastrophic. Temptations, remain, however, to pay less than due attention to some aspects of risk management. The chapter structure of the book is based on historical periods, beginning long before any important human influences, and ending with a look into what the future might hold for the species and its role in human and ecological sustainability. Almost throughout, there has been complex interplay between the technical aspects, local social and economic factors, various types of institution, the enthusiasm and drive of some very influential individuals, and tides of economic ideology, threads that needed to be woven together to do the story justice.

A comprehensive, up-to-date review of lichens as biomonitors of air pollution (bioindication, metal and radionuclide accumulation, biomarkers), and as monitors of environmental change (including global climate change and biodiversity loss) in a wide array of terrestrial habitats. Several methods for using lichens as biomonitors are described in a special section of the book.
