A Minimalistic model of spatial structuration of humid savanna vegetation

Abstract : In this work, we propose a spatio-temporal tree-grass interactions model, allowing to account for a possibly periodic spatial structuring sometimes observes in humid savanna zone. The proposed model relies on an integro-differential reaction-diffusion system, involving kernels of intra and inter-specific interactions. From a linear stability analysis performed in the vicinity of a homogeneous stationary state that denotes tree-grass coexistence, we succeed first to find a condition for the appearance of periodic solutions in space with predictable wavelength and second, to illustrate it numerically.
