What signatures of ecological processes might be discerned by comparing the spatial patterns of trees between primary and secondary forest plots? The spatial distribution of common species, and all stems collectively, was aggregated in the secondary forest plot but not different from random in the primary forest plot. Diameter and height were also strongly spatially auto-correlated in the secondary forest plot but not in the primary forest plot. Conspecific aggregations were more common in the secondary forest plot. The secondary forest plot was characterized by the presence of diversity-repelling species and lower diversity than the primary forest plot. The higher local diversity of the primary forest can be explained by the reduction of species aggregation through increased mortality of conspecifics.
