 abstract={Using model assemblages the dependence of the intercept of the power function and the exponential model of species-area relationships on slope and factor value were studied. It is shown that the quotient of intercept and total species number in the assemblage (Sunit/Sa) can be interpreted as a relation between local and regional diversity and linked with species-area relations. Two general relations are derived and tested combining both concepts: z = a / In(area) x ln Sunit/Sa, and Sunit/1 / β1Ha/1 / e β = Sunit/2 / β2Ha/2 / e β with z being the slope of the power function model, H the Shannon diversity, β, β1 and β2 constants, and a the constant of the relation between Sunit/Sa and z. It is concluded that with the above functions species-area relationships can be used to infer the relation between local and regional species numbers and to compute regional diversities.},
