In this talk, we will start by modeling the ecological dynamics of a plant and pollinator community, using a microscopic individual-based model. We will then use different renormalizations of this process in order to study the population dynamics under different assumptions. In particular, we will be interested in the assumption of large populations and the one of a large number of species. Our aim is to give parametrization under which the community is resilient following deletions of certain species or populations.
