Relationships between functional diversity and C stocks in different forest ecosystems
Recent studies focused on biodiversity have begun to include the concept of functional diversity, which measures the range, value, and distribution of functional traits of organisms in a community ecosystem (Tilman et al. 1997; Mouchet et al. 2010). It is becoming increasingly accepted that biodiversity components of plant community, i.e. the species identity, abundance and divergence of functional traits, strongly affect ecosystem productivity, functioning, litter decomposition and soil nutrients dynamics (Wardle et al. 2004, 2012; Naeem & Wright 2003; Díaz et al. 2004; Hooper et al. 2005; Mouillot et al. 2005; Cortez et al. 2007; De Deyn et al. 2008). …show more content…

Jonsson & Wardle (2009) and Wardle et al. (2012) also giving more support to mass ration hypothesis that communities dominated by acquisitive trait values showed lower below-ground C storage than communities dominated by more conservative trait values in boreal forests. In natural moist seasonal tropical forests, Ruiz-Jaen & Potvin (2011) reported that C stocks associated positively with plant height and leaf mass per area (the inverse of SLA) and negatively with the variety of values of these traits, giving more support to mass-ratio hypothesis while in neighboring plantations, in contrast, they found a negative association of C stocks with plant height and leaf mass per area and a non-significant association with variety of values of these traits, giving more weight to niche-complementarity hypothesis. Thus, it is important to consider both the mass ratio hypothesis and the complementarity hypothesis when functional diversity-C stocks associations are examined. The only study that I am aware is Cavanaugh et al. (2014), in which they partly supported the both hypotheses on the basis of functional dominance and taxonomic diversity (genus richness and Shannon diversity). However, they did not find a significant relationship between functional diversity and ACS. In their study, the functional diversity components were calculated by using the maximum diameter of stem
