In the early summer months, undergraduate Emily Meyers would rise before the sun, sometimes around 3 or 4 a.m. Keeping time by the ocean tides, she’d cart her research materials to eelgrass beds near the Bodega Marine Laboratory.
Researchers measured the physical traits and defenses of 351 butterfly fish species compared to feeding style. The fish fell into two broad groups: hunters and grazers. Hunters, with deeper bodies and bigger spines, left the reefs; grazers remained in the relative safety of the reefs.
Seagrass meadows could play a limited, localized role in alleviating ocean acidification in coastal ecosystems, according to new work led by Carnegie’s David Koweek and including Carnegie’s Ken Caldeira and published in Ecological Applications.
