Document Summary
Bef relationships ultimately arise from functional differences: complementarity competition for resources, selection probability to high performance traits, facilitation certain species modify environmental conditions. Trait quantifiable characteristic of a phenotype (usually governed by specific genes. Seek to characterise organisms in terms of their multiple biological attribtues such as physiological, morphological or life history traits. Benefits: distribution of functional traits more strongly tied to enviro conditions, response traits, can be taxon independent, link biodiversity to ecosystem function, effect traits. Effect traits: influence ecosystem-level processes (harder to understand) ** understanding the relationship b/n the two important for predicting outcome of biodiversity loss on ecosystem functioning. Trait any measurable feature of an individual that potentially affects performance or fitness. Community weighted means cwm mean trait value (single traits) weighted by species abundance or relative abundance. If there is a dominant species present, then the cwm is going to be highly affected by that species.
