Stress response mechanisms
A concept that is central to my research is that individuals of many aquatic species can vary their traits in response to changes in the environment during their lifetimes. My laboratory focuses on the central role that this plasticity plays in fish adaptive responses and resistance to environmental stressors. This research program has implications for environmental science, evolutionary biology and biomedicine. For example, by studying these plastic responses of fish under different conditions, we can test why and when a trait should evolve under natural selection. One area of interest is the plasticity of fish development in response to predators, which are ubiquitous natural stressors and fear inducers, to see how fish adapt their sensory systems to increase survival. I also have interest in the molecular basis of development to determine which genes are especially important for fish stress responses. These stressors may include abiotic factors such as rising temperatures, changes in pH, and contaminants which are all relevant to our understanding of the impact of environmental degradation on fish populations. In addition, our close evolutionary relationship with fish enables their use as a model for informing us about the impact of environmental stressors on human health. We use a variety of techniques including behavioral assays and video techniques, light and scanning electron microscopy and bioinformatics to explore these questions in fish we raise in my husbandry program.
The Team Danio undergraduate researchers raise zebrafish (Danio rerio) and explore their responses to the environment as they grow. One and nine-day-old zebrafish are shown.
