Coexistence in spatially explicit metapopulations

Abstract:

The multitype contact process is a stochastic model including space in the form of local interactions and describing the evolution of two species competing on a connected graph. While it is conjectured for the multitype contact process on the two- dimensional regular lattice that, regardless of their birth and death rates, species cannot coexist at equilibrium, we prove that two species with opposite strategies (specialist versus generalist) coexist on a connected graph including two levels of interactions.
