I am interested in how organisms adapt to environmental change, the underlying mechanisms, and implications for population persistence. Currently, I am working on the evolutionary potential and thermal reaction norms of marine sticklebacks (Gasterosteus aculeatus). My latest projects investigate the role of transgenerational plasticity (parent environment effects on offspring traits) and epigenetic variation in mediating impacts of rapid climate change. So far, I can say that maternal effects play an important role in stickleback populations’ adaptive responses to ocean warming, but also carry-over effects from grandparent environments (particularly from grandmothers) shape offspring growth, physiology and gene expression.
