They are two hypothesis proposing explanations for the positive relationship between biodiversity and productivity.
“The sampling effect hypothesis suggests that diversity effects are caused by the greater chance of one or a few dominant, high-biomass species being present in the polyculture. The niche complementarity hypothesis states that niche differences among species, such as interspecific differences in resource use, should lead to more efficient acquisition of limiting resources and therefore higher productivity. Thus, each hypothesis proposes an ecologically distinct mechanism, complementarity involving interactions among two or more species and sampling involving the presence of a particular species. ” quoted from –
