WebJoseph Connell's "intermediate disturbance hypothesis" proposes that species diversity is highest at intermediate frequencies of disturbance. species diversity is lowest at intermediate frequencies of disturbance. population growth rates are highest at intermediate frequencies of disturbance. 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".
