The earth’s climate is rapidly changing. The oceans and atmosphere are inextricably linked, which now means that increased concentrations of atmospheric carbon dioxide leads to changes in ocean chemistry. With 40% of the world’s population living within 100 km of the ocean, it is critical that we understand how marine resources will be affected.
Ecology is the study of how organisms interact with one another and their environment and how these interactions affect their populations. In the face of climate change, we are trying to understand the responses and thresholds of different organisms, identi
fy those at greater risk for extinction, and mitigation tactics to prevent and/or impede extinction.
I am interested in understanding how climate change operates at local and regional scales along the California coast, where we have several dynamic photosynthetically-driven ecosystems (e.g., seagrass beds, kelp forests, salt marshes) that provide services that would be difficult and expensive to replicate. This requires understanding individual-level and ecosystem-level responses of the organisms that form these habitats.
- CO2 and Temperature impact development of giant kelp during early life stages
- Ocean acidification influences function of the rhodolith holobiont
- Determining Chinook Salmon run-type using strontium isotopes
- pH variation in estuarine habitats – seagrass beds vs. salt marshes
