The purpose of this note is to mechanistically formulate a
mathematically tractable model that specifically deals with the
dynamics of plant-herbivore interaction in a closed
phosphorous (P) limiting environment. The key to our approach is
the employment of the plant cell P quota and the Droop
equation for its growth. Our model takes the simple form of a
system of two autonomous ordinary differential equations. It can
be shown that our model includes the LKE model (Loladze, Kuang and Elser (2000)) as a special case. Our study reveals that the details of ecological stoichiometry models really matter for quantitative
predictions of plant-herbivore dynamics, especially at
intermediate ranges of the carrying capacity.
