Document Summary

Deined as a diference to the relaive the normal condiions of the environment. Characterisics: frequency: how oten, intensity: how strong are they, localized. R-species are beter adapted for disturbances because they have a high growth rate but will get outcompeted by k-species very quickly. Highest level of diversity is at intermediate disturbance levels. Intermediate levels of producivity mean high levels of diversity (relates to bioic disturbance which would be consumers and predators) also speeds up compeiive exclusion. Reduced natural disturbance (managing forest ires, reduced compeitors, etc. )
