'It is generally believed, and indeed is often true, that species which are very similar will tend to compete, with the more effective competitor excluding the weaker. This important and interesting book shows that - to the contrary - the co-existence of similar species can greatly enrich the diversity of communities, and also can help in responding to, or recovering ...

The book uses studies of plant communities to document these general principles, placing particular emphasis on reproductive scheduling and its role in the stable coexistence of similar species. The book deserves a wide audience.' Robert M. May, University of Oxford 'Ecologists have long talked about temporal variability, such as in rainfall, but largely as perturbations to a more static, idealized equilibrium. Yet, temporal variation is a pervasive feature of the natural world, and species have evolved to exploit such variation. Species can also generate novel sources of temporal variation, such as the dramatic phenomenon of masting. This well-crafted book, containing chapters by many distinguished ecologists, draws together excellent case studies from a range of field systems, along with theory on the storage effect and evolution of masting, to champion the view that temporal variation is central to the generation and maintenance of biological diversity. It should be on the shelves of all ecologists who care deeply about the factors governing ecological communities, and about the preservation of biodiversity in our ever-changing world.' Robert D. Holt, University of Florida, and co-editor of Trait-Mediated Indirect Interactions (2012) 'The idea that species can have good years and bad years will be familiar to any observer of the natural world, but this volume takes the idea a step further: if different species have different good years then there is the basis of a mechanism that can allow competing species to coexist in a community. How species coexist in diverse communities, without one or a few outcompeting the many is a key question in our understanding of how biological communities are assembled.'
