The dependence of physiological functions on temperature and other environmental factors means that rate processes will fluctuate with the environment unless rates are buffered by compensatory responses, or the internal environment is regulated in spite of environmental variability.
I am particularly interested in plasticity induced by epigenetic mechanisms during development, and how these modulate within-individual, reversible plasticity (acclimation).
