6. Ecological determinants which regulate microbial life
6.1 Definitions and abbreviations of ecological state parameters.
- Physical and chemical constraints: temperature, proton activity, water activity,
hydrostatic pressure, wind forces and mixing of water and air masses, radiation.
- Chemical and trophic determinants: oxygen concentration, electron activity, sources
of energy, electrons, mass, trace elements and oxidants.
- Accessibility of solid nutrient compounds from rocks, minerals, precipitates
- Electron activities: the pe-concept
- Ecologically useful information derived from pe/pH stability diagrams.
