作者：Nicholas J. Gotelli and Gary R. Graves 关于作者的声明： Although Null Models in Ecology is still widely cited, it has been out of print for several years. Fortunately, Smithsonian Press returned the copyrights to the authors. My co-author Gary Graves has scanned the entire book, so we are now pleased to be able to offer it to you in complete form for downloading as a set of .pdf files. Each individual chapter is about 5 - 20 MB in size. Click on the .pdf icon to download each chapter. The text can be searched within the pdf file, which is one of the few things that cannot be said in favor of the print version. Thank you for your continued interest in this book! Gotelli, N. J. and G. R. Graves. 1996. Null Models in Ecology. Smithsonian Institution Press, Washington, D.C. --------------------------------------------------------- 内容介绍 ----------------------- Null models are statistical methods and computer simulations used to analyze patterns in nature. They have been widely applied in community ecology since the 1970s in an effort to achieve predictability and falsifiability in a discipline that previously had relied on anecdotes and localized evidence. But the use of null models has been the subject of intense debate: detractors argue that premises built into them often determine conclusions, while advocates see them as basic tools. Null Models in Ecology is the first detailed overview of this complex and controversial subject. The authors address the major issues in community ecology that have arisen in the last three decades and thoroughly explains the conceptual and mathematical bases of various null models. Chapter by chapter, the book takes up the significant areas of research to which null model analyses have been applied- including niche overlap, community assembly, the species-area relationship, and food web structure. The most detailed coverage is devoted to the heart of null model controversies: analyses of size ratios and co-occurrence patterns. Throughout, the authors address such themes as the distinction between nonrandom patterns and the mechanisms that produce them; the relative merits of conventional statistical tests and Monte Carlo simulations; and problems of redundancy and statistical independence. Steering a thoughtful and objective course through some of the most contentious ongoing debates in the field, the authors argue that, used with care and an awareness of limitations, null models can be a sophisticated and powerful method of answering ecological questions. 368 pages, 108 black & white illustrations.
