Plant-pollinator population dynamics.

We formulate and analyze a multi-generation population dynamics model for pollinators' mutualism with plants. The centerpiece of our model is an analytical expression for population-level plant-pollinator interactions extrapolated from a model of individual-level flowers and bees interactions. We also show that this analytical expression can be productively approximated by the Beddington-DeAngelis formula-a function used to model trophic interactions in mathematical ecology.
