Patterns in Nature: The Analysis of Species Co-Occurrences (Hardcover)
What species occur where, and why, and why some places harbor more species than others are basic questions for ecologists. Some species simply live in different places: fish live underwater; birds do not. Adaptations follow: most fish have gills; birds have lungs. But as Patterns in Nature reveals, not all patterns are so trivial.
Travel from island to island and the species change. Travel along any gradient—up a mountain, from forest into desert, from low tide to high tide on a shoreline —and again the species change, sometimes abruptly. What explains the patterns of these distributions? Some patterns might be as random as a coin toss. But as with a coin toss, can ecologists differentiate associations caused by a multiplicity of complex, idiosyncratic factors from those structured by some unidentified but simple mechanisms? Can simple mechanisms that structure communities be inferred from observations of which species associations naturally occur? For decades, community ecologists have debated about whether the patterns are random or show the geographically pervasive effect of competition between species. Bringing this vigorous debate up to date, this book undertakes the identification and interpretation of nature’s large-scale patterns of species co-occurrence to offer insight into how nature truly works.
Patterns in Nature explains the computing and conceptual advances that allow us to explore these issues. It forces us to reexamine assumptions about species distribution patterns and will be of vital importance to ecologists and conservationists alike.

“Unpicking why and how certain adaptations within species appear to be linked with particular habitats, the authors hope to reveal intriguing insights into community ecology.”
— Observer (UK)
“Sanderson and Pimm provide a thorough historical overview of this contentious debate between Diamond and Connor and Simberloff. This is particularly helpful for younger scientists. . . . This book serves as an excellent reminder of the importance of the clear and explicit articulation of one's research questions and hypotheses—that null models are the building blocks to hypothesis testing using a statistical-model approach. . . . Furthermore, Sanderson and Pimm provide a wise reminder that as scientists, if we are to move our science forward, sometimes it is important to revisit concepts using a fresh perspective or new technologies, regardless of the perceived scientific ‘sexiness’ of doing such a thing.”
— BioScience
“A valuable and stimulating review of decades of work. The focus on intellectual content is refreshing, because there seems little to be gained from rekindling what the authors term an ‘academic war,’ and, overall, I feel that the major contributions arising from both entrenched positions are well recognized here (the occasional pointed aside notwithstanding). There is a clear moral too, that increased openness can help us to avoid future ‘wars.’ . . . Was it worth these decades of hostility? Are we now in a much stronger position to robustly predict how ecological communities will respond to an uncertain future? I am not sure. But, I am convinced by the authors’ statement that doing so will require increased cooperation between those able to identify, analyze, and explain repeated patterns in nature.”
— Thomas J. Webb, University of Sheffield
“Sanderson and Pimm . . . are not about to let the dust settle. Their text is an accessible summary of the crux of the debate, and an attempt to persuade a general readership that the proper design of null models provides the key to resolving all such disagreements. . . . What they achieve in their book, rather than a resolution, is to resurrect the debate in the light of recent theoretical developments, particularly the means to more fully explore the null model space. Regardless of whether you ultimately agree with their conclusions, this makes it an important and worthwhile read.”
— Markus Eichhorn, University of Nottingham
“The strength of the book is that it goes beyond simply revisiting a historical debate, in which the authors themselves participated, to present a robust way forward that draws on insights gained from a range of re-analyses, including those central to perhaps the most heated debate in ecology. An exciting next step would be to take advantage of modern computing power and apply this approach to a wider array of taxa and localities to more fully understand how species interactions structure ecological communities across scales.”

“Two fundamental questions of community ecology concern large-scale patterns of species communities. Do such patterns really exist? If they do exist, how can they be explained? Difficulties in answering these questions have given rise to much debate over the course of the last forty years. By assembling massive new databases and powerful new analytical techniques, Sanderson and Pimm have now produced this wonderfully clear account of this wonderfully complex subject. This book will be the standard reference work for everyone interested in the patterns of species communities.”
— Jared Diamond, University of California, Los Angeles
“This stimulating book is centered upon an attempt, inspired by Robert MacArthur, to explain patterns of co-occurrences of bird species that might be caused by competition. Are the patterns real or no different from what is expected by chance? The authors adopt an engaging conversational style in confronting the contentious issues and surprising complexity of distinguishing between these stark alternatives. The book will be valuable in showing how ecologists grapple with fundamentally different opinions on how to analyze data.”
— Peter R. Grant, Princeton University
“A very interesting book on large-scale species distribution patterns, this is not a repeat of what has been published voluminously on the debate between Diamond and Connor/Simberloff, but a well-written, fairly balanced, and updated account of the positive contributions to science from both camps and the lessons that we all can learn from such heated debates. For those who are interested in island biogeography, for those who are enthused by ‘laws’ in ecology, and for those who are intrigued by historical developments in community ecology and beyond, this is a fascinating read. And for those who want to learn useful techniques and algorithms in null model analysis, Patterns in Nature is an entertaining and valuable book.”
