a Adaptive evolutionary dynamics show species packing increases faster with CNDD. Simulations start from a single ancestor with \(r={r}_{\min }\) and speciation occurs as a mutation in a single trait (allocation to reproduction) evolving as a jump process. The success of establishment in the local community and extinction in the metacommunity are based on the outcome of the competition model, which is evaluated after each speciation event. b Species richness as function of the CNDD parameter for an evolutionary time equal to 150 speciation events. Each point represents an independent simulations. Linear regression, (\(n=600\)) shown for reference (solid line). c Comparison of species richness as function of metacommunity size with a single-trait evolution (allocation to reproduction) and a multi-trait evolution (allocation to reproduction and allometric parameter relating crown size to biomass). Each point represents an independent simulations. Linear regressions (\(n=600\)) shown for reference (solid lines).
