I am investigating the roles of competition, mutualism, and diseases in mediating the impact of ocean acidification on seagrass ecosystem health and functioning. Using both laboratory- and field approaches, I am exploring these questions with surfgrass Phyllospadix spp., ubiquitous foundation species along the California coast, as well as Neptune grassPosidonia oceanica, which is a major conservation concern in the Mediterranean.

Paul studies the physical drivers and ecological consequences of coastal hypoxia within kelp forest ecosystems through oceanographic measurements and laboratory experiments. He is also developing new, low-cost sensors for quantifying physical variability in the ocean.
I am interested in the effects of climate change stressors on organisms’ functional roles, and how these organism-level effects can scale up to impacts on ecological communities and ecosystems. In particular, I am exploring how variation in sea urchins’ responses to low dissolved oxygen (hypoxia) and temperature can be used to predict the effects of these stressors on the structure and function of kelp forest ecosystems, via changes in grazing.
I am researching how climate change stressors affect grazing communities in giant kelp forests within Monterey Bay. By conducting both lab and field work, she is focusing on how the interaction between different grazing species and juvenile giant kelp will be affected by hypoxia and ocean acidification. Through this work, we can better understand which interactions might emerge as “winners” or “losers” under future climate change scenarios. Profile page: http://hopkinsmarinestation.stanford.edu/ng
