The intermediate disturbance hypothesis (IDH) suggests that local species diversity is maximized when ecological disturbance is neither too rare nor too frequent. At low levels of disturbance, more competitive organisms will push subordinate species to extinction and dominate the ecosystem. At high levels of … See more David Wilkinson gives a thorough history of the hypothesis in his paper titled, "The disturbing history of the intermediate disturbance". In this paper, he explains that the idea of disturbance relating to species richness … See more • Competition-colonization trade-off • Ecological succession • Habitat fragmentation See more Debates over the validity of the IDH are ongoing within the discipline of tropical ecology as the theory is tested in various ecological communities. Other evidence exists for and against the hypothesis. The intermediate disturbance hypothesis has been supported by … See more Webintermediate disturbance hypothesis (IDH), that species diversity would be highest at a moderate intensity of disturbance (Connell 1978, Huston 1979), are relevant in this context. Support for IDH has been found in many ecosystems (e.g., Floder and Sommer 1999, Buckling et al. 2002) but not in others (e.g., Mackey and Currie 2001, Shea et al ...
