I am a PhD candidate at the UC Davis Bodega Marine Laboratory, and I expect to complete my degree in June 2012. I am interested in how invertebrates with complex life cycles respond to natural and anthropogenically-induced environmental change, and how responses fluctuate as a function of environmental variation. For my PhD work I used laboratory and field experiments to study the effects of multiple stressors (ocean acidification, tidal elevation gradients, nutrition, and temperature) on the early life stages of the North American Pacific coast native Olympia oyster (Ostrea lurida). The potential for interactive effects of multiple stressors creates complexity in understanding and predicting consequences of global change for natural populations. The task is made even more difficult by the presence of complex life cycles where sequential life stages exhibit different characteristics that may cause them to respond in distinct ways to alterations to the environment. A growing body of work suggests that abiotic and biotic stresses experienced during one life stage frequently carry over to influence subsequent life stages. To increase our capacity to predict how global change will impact natural populations, there is a strong need to understand how environmental changes are transmitted across and influence transitions of life-history stages in key organisms.
