    The diversity of tropical trees has captivated botanists for centuries. Woods of difterent species, not only differ in appearance, but also in functional traits-density, porosity and strength-characteristics that relate to various plant functions such as support and conduction. The specific gravity (SG) of wood is a species' trait that integrates mechanical strength properties and sometimes efliciency of conduction and resistance to embolism (Chave et al., 2009; Zanne et al., 2010). In addition, where light is limiting, growth rates and mortality rates are often inversely related to species' wood specific gravities; thus, fast growing pioneers exhibit low SG wood relative to mature forest species (Kraft et al., 2010; Wright et a1., 2010).
