Document Summary

Compare and contrast the diversity-stability hypothesis and the biodiversity-ecosystem functioning (bef) hypothesis. Bef: postulates that ecosystems with more species are likely to not only increase stability but also maximize ecosystem function (eg productivity)-ecosystem function is a consequence of diversity. The idea that biological diversity enhances ecology stability. Tilman conducted 7 year study on the functional response of grasslands to varying species richness (using functional group) Results: both aboveground productivity and biomass increased with richness: graphically represent an example of a three-way interaction between a carnivore, a herbivore and a plant. Carnivore
