Book excerpt: Excerpt from Sequential Sampling of Hemlock Sawfly Eggs in Southeast Alaska Choice of a decision line probability level is made before sampling is begun. The inner decision lines?/ in figure 3 are the least precise since they can be expected to give an incorrect decision one out of five times, but the number of sample trees required is minimal. The outer decision lines are the most precise since they can be expected to give an incorrect decision only one out of 20 times, but the number of sample trees required is greatly increased. The intermediate decision which can be expected to give an incorrect decision one out of 10 times, are adequate for most sampling.

Available in PDF, EPUB and Kindle. Book excerpt: This best-selling majors ecology book continues to present ecology as a series of problems for readers to critically analyze. No other text presents analytical, quantitative, and statistical ecological information in an equally accessible style. Reflecting the way ecologists actually practice, the book emphasizes the role of experiments in testing ecological ideas and discusses many contemporary and controversial problems related to distribution and abundance. Throughout the book, Krebs thoroughly explains the application of mathematical concepts in ecology while reinforcing these concepts with research references, examples, and interesting end-of-chapter review questions. Thoroughly updated with new examples and references, the book now features a new full-color design and is accompanied by an art CD-ROM for instructors. The field package also includes The Ecology Action Guide, a guide that encourages readers to be environmentally responsible citizens, and a subscription to The Ecology Place (www.ecologyplace.com), a web site and CD-ROM that enables users to become virtual field ecologists by performing experiments such as estimating the number of mice on an imaginary island or restoring prairie land in Iowa. For college instructors and students.

Invasive species have caused and will continue to cause enormous ecological and economic damage with ever increasing world trade. This multi-disciplinary book, written by over 100 national experts, presents the latest research on a wide range of natural science and social science fields that explore the ecology, impacts, and practical tools for management of invasive species. It covers species of all taxonomic groups from insects and pathogens, to plants, vertebrates, and aquatic organisms that impact a diversity of habitats in forests, rangelands and grasslands of the United States. It is well-illustrated, provides summaries of the most important invasive species and issues impacting all regions of the country, and includes a comprehensive primary reference list for each topic. This scientific synthesis provides the cultural, economic, scientific and social context for addressing environmental challenges posed by invasive species and will be a valuable resource for scholars, policy makers, natural resource managers and practitioners.
Book Synopsis Bark and Wood Boring Insects in Living Trees in Europe, a Synthesis by : François Lieutier
Download or read book Bark and Wood Boring Insects in Living Trees in Europe, a Synthesis written by François Lieutier and published by Springer Science & Business Media. This book was released on 2007-08-24 with total page 569 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the first time, a synthesis on the research work done in Europe on all Bark And Wood Boring Insects In Living Trees (BAWBILT) is presented. As final product of a four-year research project gathering together 100 scientists from 24 countries, the book is the fruit of a real collective synthesis in which all European specialists have participated. It reviews and comments on all the European literature, while considering the biological (trees, insects, associated organisms, and their relationships) and forest management aspects. However, although focused on the European forest, it also compares the available information and interpretations to those concerning similar species in other continents. It ends with propositions of research priorities for Europe. The book is directed to all scientists and students concerned with forest entomology and ecology, as well as to forest managers and all scientific public interested in forest biology.
