Table 1 The 38 PSFI scenarios used in this study with details on the heterospecific interaction type (negative implies growth rates of species are slow (slow = 1.49 time step⁻¹) in heterospecific soil, positive implies growth rates of species are fast (fast = 1.82 time step⁻¹) in heterospecific soil, otherwise heterospecific growth rate is equal to the standard growth rate (standard = 1.65 time step⁻¹); group size (changing the number of species that interacted in each module for the modular networks, changing the number of highly interactive species for nested networks, changing the number of species that interacted with other species for ring scenarios); and conspecific interactions (“None” implies growth rates of species are standard in conspecific soil, “Negative” implies growth rates of species are slow in conspecific soil and are indicated by adding NC suffix onto the PSFI scenario name). Information on heterospecific network scenarios with and without negative conspecific interactions are combined in the same row, and separated by a “/”, with information on the scenario without conspecific interactions presented first.
