Biodiversity and Biogeochemical Cycles,ore and Sayer 1992). 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

Microbial Diversity and Tropical Forest Functioning,992). An overview of the role of microorganisms in ecosystem functioning as a whole has already been presented (Allsopp et al. 1995). 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

Functional Group Diversity and Responses to Disturbance,) and creation of establishment sites for seedlings (Brokaw 1985; Denslow 1980a, 1987). 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

Species Richness and Resistance to Invasions,iversity and stability (Elton 1958). Unfortunately, ecologists have used the word’ stability’ to mean several different things (Orians 1975; Harrison 1979; Pimm 1984): . can be defined as a rate of return of population densities, community composition, or collective properties like biomass productio
