From: On the repulsive interaction between localised vegetation patches in scarce environments

Localised vegetation patches in model Eq. (1). (a) Typical bifurcation diagram (χf > 1 + χc), biomass b as function of effective aridity η = μ − 1. ηc stands for to the spatial instability threshold. ηI and ηII delimit the region where localised vegetation patches are observed. (b) Localised vegetation patch obtained from numerical simulation of model Eq. (1) for μ = 1.04, χf = 2, χc = 1, D = 1, \({\Phi }_{f,c}({\bf{r}})={e}^{-| {\bf{r}}| /{\sigma }_{f,c}}/{\sigma }_{f,c}\), σc = 4.5, and σf = 0.05. (c) Temporal evolution of localised vegetation patches (t1 < t2 < t3), from a random initial distribution of localised vegetation patches.
