The Spring 2018 Biology Seminar Series concludes with Andrea Bonisoli-Alquati’s talk, "Oxidative stress and life history: Ecological and evolutionary lessons from nuclear accidents.”
Exposure to ionizing radiation can imbalance the antioxidant system, inducing oxidative stress. The oxidative status of an organism is increasingly regarded as the currency underlying life history trade-offs, such as the one between survival and reproduction. Landscape-level radioactive contamination can thus function as a natural laboratory where to investigate the nexus between life-history and physiology. The talk will review recent findings from research in Chernobyl and Fukushima, and highlight how oxidative stress can be seen as a thread underlying many of the effects of radioactive contamination, from the organismal level to communities.
