The MacArthur-Wilson equilibrium model of island biogeography predicts the number of species found on islands. The figure below depicts two volcanic islands located off a section of mainland coast.
The MacArthur-Wilson model predicts that the relative numbers of bird species on the mainland and two islands would be
