Document Summary
The variability among living organisms from all sources and the ecological complexes of which they are part; includes diversity within and among species and ecosystems. Complementarity: increased coverage of available niche-space, ecological services will be highest/fastest in a community in which all resources or microenvironments are being exploited; some evidence of that form the biocon and biodiv experiments. Sampling effect: increased chance of having great" species, as the # of species in a community increases, the changes of a community containing a really functionally important species increases too. Balvanera et al. (2006) meta-analysis from 103 studies. Choose species pool, randomly select species per plot. Biomass increases with increased biodiversity; effect increases over time. Some functional groups have more of an effect than others, therefore their diversity may be more important. Herbivore diversity may not matter as much as plant diversity, but mycorrhizal fungi are very important.
