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.

Coral reefs, seagrass meadows and mangrove forests work together to make the Coral Triangle of Indonesia a hotspot for marine biodiversity. The system supports valuable fisheries and endangered species and helps protect shorelines. But it is in global decline due to threats from coastal development, destructive fishing practices and climate change.
