For insects, several hypotheses have been invoked when attempting to explain coexistence under equilibrium conditions. McClure and Price (1975) suggest that coexistence in a gui

Usually, this competition has been observed by ecologists working with vertebrates (MacArthur 1972), plants (Harper 1977), or intertidal marine organisms (Paine 1974). Entomologists, on the other hand, have less frequently included interspecies amo

The former methods enable the parametric adaption of the system’s behavior, e.g. an adaption of controller parameters, according to a current selection of th
