Acclimation and Evolution
How an individual perceives environmental stress (e.g. social, physiological, nutritional, toxins) and responds at the molecular level (genetic and cellular changes), can affect how that individual behaves, its ability to reproduce, and its lifespan. My research integrates environmental variation, molecular networks, and life history to investigate how organisms respond to their environment at the individual level (plasticity and acclimation) and how this response can evolve across populations and across species. I am currently working on projects that address the following questions: 1) How do gene networks that link physiological stress and life-history traits evolve? 2) What is the persistence (transient, lifetime, or transgenerational) of epigenetic modification to the genome in response to physiological stress in ectotherms, and do these modifications play a role in adaptive acclimation within and across generations.
