We will examine regulation at several levels in an in several contexts.
metabolic time scale - regulation of enzyme activity
growth time scale - regulation of protein synthesis
interaction of regulation at these two levels (the two component model)
epigenetic time scale - differentiation (such as formation of heterocysts or stress responses)
population time scales (multiple generations, but less than evolution) - intra-clonal variability
competition - metabolic and genetic regulation that leads to optimization of physiological components
competition - regulation in a variable environment for optimal growth rates
survival - regulation in variable environments for survival of the "species"
simple: (mechanistic, cause and effect)
simple (dynamic): time course of response and interaction, secondary responses
systems: multiple interacting elements (not cause and effect)
descriptive:rich description of the behavior in the linguistics of regulation
complex: basins and "switches" in behaviors
