Tropical forests include the most floristically diverse habitats on the planet. Although it is well established that species richness influences processes in species-poor ecosystems, the effect of an increase from p

Keystone species such as predators that prey selectively on competitive dominants or plants that fruit during seasons of scarcity can have profound effects on entire ecosys

For example, it is well known that the replacement of diverse tropical forests with less species-rich systems results in the loss of genetic resources and of new, potentially useful plants and animals. Global-scale changes are also likely to have an impact on biodiversity, both

Here, our goal is to identify the functional attributes of microorganisms in tropical forests, and to identify those processes that are most likely to be sensitive to

However, intense, repeated, and extensive human disturbance causes high rates of species extinctions (Wilson 1988). The debate on how best to manage tropical forests commercially shows that the relations between
