By making the substitution J = ρ A {\displaystyle J=\rho A} (see section on saturation above), then the expected number of species becomes Σ θ / ( θ + ρ A − 1 ) {\displaystyle \Sigma \theta /(\theta +\rho A-1)} .
Facendo a substitución de J = ρ A {\displaystyle J=\rho A} (véxase a sección de saturación de enriba), logo, o número de especies que se espera pasa a ser Σ θ / ( θ + ρ A − 1 ) {\displaystyle \Sigma \theta /(\theta +\rho A-1)} .
