Although ecologists have long considered morphology and life history to be important determinants of the distribution, abundance, and dynamics of plants in nature, this book contains the first theory to predict explicitly both the evolution of plant traits and the effects of these traits on plant community structure and dynamics. David Tilman focuses on the universal requirement of terrestrial plants for both below-ground and above-ground resources. The physical separation of these resources means that plants face an unavoidable tradeoff. To obtain a higher proportion of one resource, a plant must allocate more of its growth to the structures involved in its acquisition, and thus necessarily obtain a lower proportion of another resource. Professor Tilman presents a simple theory that includes this constraint and tradeoff, and uses the theory to explore the evolution of plant life histories and morphologies along productivity and disturbance gradients. The book shows that relative growth rate, which is predicted to be strongly influenced by a plant's proportional allocation to leaves, is a major determinant of the transient dynamics of competition. These dynamics may explain the differences between successions on poor versus rich soils and suggest that most field experiments performed to date have been of too short a duration to allow unambiguous interpretation of their results.

Plant Strategies, Vegetation Processes, and Ecosystem Properties, Second Edition, is a thoroughly updated and comprehensive new edition of the very successful Plant Strategies and Vegetative Processes, which controversially proposed the existence of widely-recurring plant functional types with predictable relationships to vegetation structure and dynamics. This second edition uses evidence from many parts of the world to re-examine these concepts in the light of the enormous expansion in the literature. Features include: * A new section covering all aspects of ecosystem properties * New chapters on Assembling of Communities Rarification and Extinction Colonisation and Invasion * Principles and methodologies of a range of international tests including case study examples * Chapter summaries for a quick reference guide * Index of species names Written in a very readable style, this book is an invaluable reference source for researchers in the areas of plant, animal, and community ecology, conservation and land management. 'Written by one of the foremost authorities in the field, summarising over 35 years of research. A book all plant ecologists will want to read.' - Jonathan Silvertown, Department of Biological Sciences, The Open University, UK. 'The coverage is outstanding and comprehensive.' - Simon A. Levin, Department of Ecology and Evolutionary Biology, Princeton University, USA

Ever since the concept of the "struggle for life" became the heart of Darwin's theory of evolution, biologists have studied the relevance of interactions for the natural history and evolution of organisms. Although positive interactions among plants have traditionally received little attention, there is now a growing body of evidence showing the ef

Much of what is considered conventional wisdom about succession is not as clear cut as it is generally believed. Yet, the importance of succession in ecology is undisputed since it offers a real insight into the dynamics and structure of all plant communities. Part monograph and part conceptual treatise, An Integrative Approach to Successional Dynamics presents a unifying conceptual framework for dynamic plant communities and uses a unique long-term data set to explore the utility of that framework. The fourteen chapters, each written in a nontechnical style and accompanied by numerous illustrations and examples, cover diverse aspects of succession, including community, population and disturbance dynamics, diversity, community assembly, heterogeneity, functional ecology and biological invasion. This unique text will be a great source of reference for researchers and graduate students in ecology and plant biology, as well as others with an interest in the subject.

Provides a comprehensive review of the role of species interactions in the process of plant community assembly.

How do plants make a living? Some plants are gamblers, others are swindlers. Some plants are habitual spenders while others are strugglers and miserly savers. Plants have evolved a spectacular array of solutions to the existential problems of survival and reproduction in a world where resources are scarce, disturbances can be deadly, and competition is cut-throat. Few topics have both captured the imagination and furrowed the brows of plant ecologists, yet no topic is more important for understanding the assembly of plant communities, predicting plant responses to global change, and enhancing the restoration of our rapidly degrading biosphere. The vast array of plant strategy models that characterize the discipline now require synthesis. These models tend to emphasize either life history strategies based on demography, or functional strategies based on ecophysiology. Indeed, this disciplinary divide between demography and physiology runs deep and continues to this today. The goal of this accessible book is to articulate a coherent framework that unifies life history theory with comparative functional ecology to advance prediction in plant ecology. Armed with a deeper understanding of the dimensionality of life history and functional traits, we are now equipped to quantitively link phenotypes to population growth rates across gradients of resource availability and disturbance regimes. Predicting how species respond to global change is perhaps the most important challenge of our time. A robust framework for plant strategy theory will advance this research agenda by testing the generality of traits for predicting population dynamics.
