Seagrass

Celebrating Seagrass

In celebration of World Seagrass Day, we're highlighting seagrass-focused research conducted by UC Davis graduate students. Meet some of our dedicated scholars and delve into their research, exploring the significance of seagrasses and the implications for marine environments.

Genome Study Shows Recent Spread of Eelgrass

Beds of eelgrass (Zostera marina) form an important habitat in coastal regions throughout the northern hemisphere, crucial to many fish and other species and storing vast amounts of carbon. A new study published July 20 in Nature Plants shows that eelgrass spread around the world much more recently than previously thought, just under a quarter-million years ago. The results have implications for how eelgrass could be affected by a changing climate.

World Seagrass Day

Join us in a celebration of all things seagrass! March 1st is World Seagrass Day, and we're taking an in-depth look at what seagrasses are, how they interact with marine coastal ecosystems, and how they're being impacted by climate change.

Seagrasses Turn Back the Clock on Ocean Acidification

Seagrasses Turn Back the Clock on Ocean Acidification Expansive Study Shows Seagrass Meadows Can Buffer Ocean Acidification

Spanning six years and seven seagrass meadows along the California coast, a paper published today from the University of California, Davis, is the most extensive study yet of how seagrasses can buffer ocean acidification.

"Suzie and the Eelgrass Geese" Book Release

Suzie and the Eelgrass Geese is the story of a young girl who lives in a small town on the coast of California whose love of the ocean leads her to work with a Professor at a local marine lab on an experiment that teaches important lessons about the balance of nature.

Semiconductors to Seagrass: An Electrical Engineering Student’s Summer Studying Marine Ecology

Seagrasses, specifically the species Zostera marina (or eelgrass), provide vital ecosystem services, such as nursery habitat for fish, sediment stabilization, and increased water clarity by slowing down waves. Unfortunately, seagrass populations have been in severe decline over the last century. Some of this is due to seagrass wasting disease, but much is due to human influences. A type of algae called epiphytes grows on the surface of seagrasses, and normally causes their hosts no harm. But when nutrients flow into the ocean (for example

High variability of Blue Carbon storage in seagrass meadows at the estuary scale

By Aurora M. Ricart, Ph.D.

Seagrass meadows are considered important natural carbon sinks due to their capacity to store organic carbon (Corg) in sediments. However, the spatial heterogeneity of carbon storage in seagrass sediments needs to be better understood to improve the accuracy of Blue Carbon assessments, particularly when strong gradients are present. We performed an intensive coring study within a sub-tropical estuary to assess the spatial variability in sedimentary Corg associated with seagrasses, and to identify the key factors promoting this variability.
