Parameter dependence of the size of the abundant resource premium (ARP)-driven niche space for type 1 (left panels) and type 2 (right panels). Niche sizes are measured by the number of sampled points on the (ln Be, ln C)-plane, which is different from Fig. 5, where the size of the niche is defined by the area on the (ln Be, ln C)-plane. Symbols and parameters are the same as in Fig. 5. The thick black dashed curve labelled by Dwo indicates the difference between the niche spaces of the realised
