Box 9E. 1 Continued FIGURE 2. The C–S–R triangle model (Grime 1979). The strategies at the three corners are C, competiti- winning species; S, stress-tolerating s- cies; R,ruderalspecies. Particular species can engage in any mixture of these three primary strategies, and the m- ture is described by their position within the triangle. comment briefly on some other dimensions that Grime’s (1977) triangle (Fig. 2) (see also Sects. 6. 1 are not yet so well understood. and 6. 3 of Chapter 7 on growth and allocation) is a two-dimensional scheme.

Hans Lambers is an Emeritus Professor of Plant Biology at the University of Western Australia, in Perth, Australia, and a Distinguished Professor at China Agricultural University, in Beijing, China. He did his undergraduate degree at the University of Groningen, the Netherlands, followed by a PhD project on effects of hypoxia on flooding-sensitive and -tolerant Senecio species at the same institution. From 1979 to 1982, he worked as a postdoc at the University of Western Australia, Melbourne University, and the Australian National University in Australia, working on respiration and nitrogen metabolism. After a postdoc at his alma mater, he became Professor of Ecophysiology at Utrecht University, the Netherlands, in 1985, where he focused on plant respiration and the physiological basis of variation in growth rate among herbaceous plants. In 1998, he moved to the University of Western Australia, where he focused on plant mineral nutrition, especially in legume crops and native species occurring on severely phosphorus-impoverished soils in a global biodiversity hotspot in southwestern Australia and southeastern Brazil. He has been Editor-in-Chief of the journal Plant and Soil since 1992 and featured on the first ISI list of highly cited authors in the field of animal and plant sciences (since 2002), and on several other ISI lists more recently. He was elected Fellow of the Royal Netherlands Academy of Arts and Sciences in 2003, and Fellow of the Australian Academy of Science in 2012. He received Honorary Degrees from three Universities and from the Academy of Sciences in China.

Rafael S. Oliveira is a Professor of Ecology at the University of Campinas (UNICAMP), Brazil. He did his undergraduate degree at the University of Brasília, Brazil, followed by a PhD on water relations of Amazonian and savanna trees at the University of California, Berkeley, USA. He worked as a postdoc from 2005 to 2007 at the National Institute of Space Research and the University of São Paulo in Brazil to improve the representation of key vegetation processes on climate models, followed by a project on the ecohydrology of tropical montane cloud forests. In 2007, he became Professor at UNICAMP. His research focuses on plant hydraulics, vegetation-climate feedbacks, and mineral nutrition of tropical plants. He is an Associate Editor for the journal Functional Ecology and Section Editor for Plant and Soil.
