Negative plant–soil feedback predicts tree-species relative abundance in a tropical forest
It is found that tree species that showed stronger negative feedback were less common as adults in the forest community, indicating that susceptibility to soil biota may determine species relative abundance in these tropical forests.
Importance of nurse logs as a substrate for the regeneration of pioneer tree species on Barro Colorado Island, Panama
If establishment on logs eventually leads to recruitment to the forest canopy, then logs may promote the maintenance of diversity by favouring a different group of species from those that recruit in soil.

At present little is known about the host affinity of fungi associated with seeds of tropical trees, and consequently, whether seed-infecting fungi influence plant species coexistence through differential infection of, or effects on, potential hosts.
Habitat partitioning among neotropical pioneers: a consequence of differential susceptibility to browsing herbivores?

Conditions in ~40-year-old secondary forests no longer support the recruitment of Cecropia species, which are canopy dominants there; among congeners, differences in plant traits with little apparent cost to growth can have large impacts on recruitment by affecting palatability to herbivores.
Description of a nest of Euglossa heterosticta from Peru, with taxonomic notes (Hymenoptera: Apidae)
The nest of Euglossa ( Eug Lossa ) heterosticta Moure is described as the first aerial nest in the otherwise cavity-nesting purpurea -group, and taxonomic notes are provided for the heretofore unknown female.
