Research Abstract |
The objective of this study was to theoretically explore the biological effects on physicochemical environmental conditions from the stand point of ecology, evolution, and geochemistry. Mathematical models describing microbial ecosystems were analytically and numerically examined to compare the behavior of the models with and without microbial effects on environmental conditions (pH, concentrations of nutrients and heavy metals, and Gibbs free energy etc.) . The results indicated that microbial effects on environmental conditions affect ecosystem stability and population extinction risk. Furthermore, microbial activities may control fluxes and speciation of redox species, and consequently the Gibbs energy of ecosystems.
