Superprocesses are idealized models for the evolution of a population with geographical structure/motion and (unisex) reproductive behaviour. In this paper, the reproductive behaviour, in particular the offspring distribution, is related to an exterior process (the environment). We characterize these superprocesses as the unique solution of certain evolution equations. We also prove that they can be obtained as limits of systems of branching particles with minimal variance branchings and faster (non–classical) branching rates.
