Investigating the Seagrass Microbiome

By Karley Marie Lujan

Seagrass carpets the seafloor creating a unique and vital ecosystem in shallow marine environments. Sea turtles graze on seagrass leaves while smaller organisms seek refuge in the green fields but, on the microscopic level, seagrass is also home to microbial communities. Such microbes compose the seagrass microbiome and potentially play a role in seagrass ecology.

UC Davis graduate student Cassie Ettinger identifies and characterizes seagrass-associated microbial communities. A study published last year in the journal PeerJ suggests how understanding the role of these microbes could reveal new information about seagrass sulfur cycling and establish seagrass as a model organism.

Scientist’s Talk on TEDGlobal Stage Featured on TED.com

By Kat Kerlin

Mike Gil is used to spreading the word about his love of science through his nonprofit sciall.org and its YouTube channel, but he’s about to get a bigger audience. His TED Talk, recorded last summer, was posted today on TED’s main channel. Only a fraction of talks given at TED conferences are posted to the main website, which has millions of subscribers.

“Who here is fascinated by life under the sea?” he asked the audience in his opening line. All hands go up.
