Extended Data Fig. 8: Properties of species leading to a high per capita population growth rate at low abundances.
From: Latitudinal scaling of aggregation with abundance and coexistence in forests
The panels a) – d) show different quantities that determine the per capita population growth rate \({\widetilde{\lambda }}_{f}({N}_{f})\) (eq. 11a, 13). a, the mean relative abundance Nf*/J*, which drives the risk factor ρf, averaged over all species of a given plot in dependence on latitude, b, same as a), but for the quantity \({({N}_{s}/{N}_{f}^{* })}^{{b}_{f}+1}\) as it appears in eq. 2. c, same as a), but for the mean of the risk factor \({\rho }_{f}\) for niche differences (red) and no niche differences (black), d, same as a), but for the mean of the quantity kfh/(kff –kfh,). To outline the overall tendency in the data we fitted in panels a) a polynomial regression of order 2, and in panels b) and c) an exponential regression. For plot acronyms see Extended Data Fig. 2.
