TL;DR: The degree of aggregation in the distribution of 1768 tree species is examined based on the average density of conspecific trees in circular neighborhoods around each tree, and it is found that nearly every species was more aggregated than a random distribution.

TL;DR: These findings suggest that tropical protected areas are often intimately linked ecologically to their surrounding habitats, and that a failure to stem broad-scale loss and degradation of such habitats could sharply increase the likelihood of serious biodiversity declines.

Species-area and species-individual relationships for tropical trees : a comparison of three 50-ha plots

TL;DR: The results provide support for the view that within each tree community, many species have their abundance and distribution guided more by random drift than deterministic interactions and demonstrate that diversity studies based on different stem diameters can be compared by sampling identical numbers of stems.

TL;DR: The fusion method can be applied at any scale including the policy-relevant national level, where it can provide improved biomass estimates by integrating existing regional biomass maps as input maps and additional, country-specific reference datasets.

TL;DR: It is shown that most tree species are extremely rare, meaning that they may be under serious risk of extinction at current deforestation rates, and a methodological framework for estimating species richness in trees is provided that may help refine species richness estimates of tree-dependent taxa.
