Unformatted text preview: constant if O = E , diversity will increase if O > E (speciation rates exceed extinction rates) and decrease if O<E . Diversity might be maintained at a constant level if an increase in O was matched with an increase in E: is there an equilibrium diversity ? This could only be achieved if there was some feedback between N, O and E to keep O and E in approximate balance. Consider a graphical model where the equilibrium number of species depends on the effect of N on the values of E and O (see figure)....
