Shown is a partial bifurcation diagram depicting different forms of community assembly along the precipitation axis, as computed by integrating the model equations in time. Stable, spatially uniform communities, (solid dark-green line), shift to stress-tolerant species (higher χ), as precipitation decreases. When the Turing threshold, , is traversed, spatial self-organization shifts the community back to fast-growing species (lower χ), and keep it almost unaffected as the fairly horizontal solution branches, (light green line), representing periodic patterns of wavenumber k1, and (yellow line), representing patterns of lower wavenumber k2, indicate. The insets show biomass distributions in the (χ, ) plane for representative precipitation values. The unstable solution branch describing uniform vegetation (dashed line) was calculated by time integration of the spatially decoupled model.
