The “intermediate disturbance hypothesis” and the “intermediate productivity hypothesis”
have been widely recognized concepts for explaining patterns of species diversity for the …

Summary 1 Plant ecologists have developed numerous ways to measure competition and to
rank the effects of competition relative to other factors. According to one line of logic, there is …

Analyses of growth response to resource availability are the basis for interpreting whether
trophic trade‐offs contribute to diversity. If different species respond most to resources that …

Productivity and disturbance are major determinants of species diversity, and results from
theoretical models predict that species richness should peak at intermediate levels of both …

This essay is about competition as an ecological and evolutionary force, and about theory in
community ecology, particularly competition theory. It responds to Connell (1980), Strong et …

A leading idea about how disturbances and other environmental fluctuations affect species
diversity is the intermediate disturbance hypothesis (IDH). The IDH states that diversity of …

Enrichment of competitive ecosystems may, in certain cases, lead to the extinction, rather
than the enhancement, of desirable species. Simply testing for the effects of enrichment in a …

A new hypothesis, based on differences in the rates at which populations of competing
species approach competitive equilibrium (reduction or exclusion of some species), is …

The effect of species diversity on ecosystem productivity is controversial, in large part
because field experiments investigating this relationship have been fraught with difficulties …
