Stress test to predict how diatoms will react to ocean acidification

Diatoms are microscopic phytoplankton that are the foundation for many aquatic food webs, and are responsible for 40 percent of the total carbon sequestered in our oceans and release about 20 percent of the world's breathable oxygen. The impacts of ocean acidification on diatoms have not been completely understood, but a study titled " Ocean Acidification Conditions Increase Resilience of Marine Diatoms," published today in the journal Nature Communications, provides context.

"To date, the effects of ocean acidification on diatoms have been mixed, mainly because of the complex interactions between the biology and physical chemistry. We decided to take a new and different approach to this biological question by exposing the diatom to a stress test," said Dr. Jacob Valenzuela, a postdoctoral fellow in ISB's Baliga Lab and lead author on the study. "By using a systems biology approach in conjunction with a stress test, we were able to demonstrate diatom resilience increases under ocean acidification conditions," Valenzuela said.
