Fig. 2: Latitudinal variation in the scaling of conspecific aggregation with abundance.
From: Latitudinal scaling of aggregation with abundance and coexistence in forests

a, Aggregation values for species in a tropical forest (Mo Singto (MST) plot) plotted over their respective abundances per ha (dots) and fitted linear regression between ln(kff) and ln(Nf) (line). b, Same as a, but for a temperate forest (Donglingshan (DLS) plot). c, Latitudinal gradient in the exponent of the aggregation–abundance relationship for the 21 forest plots. To show the overall trend in the data, we fit a linear regression. Aggregation is defined in Box 1 equation (3) and was estimated for neighbourhoods of 15 m. We used in our analyses 720 species with at least 50 large trees20 (diameter at breast height ≥ 10 cm). For plot characteristics, sample sizes and plot acronyms see Extended Data Table 1. Circles of subtropical plots are marked with a red edge.
