May 25, 2017 | More stuff on the beach

More stuff washed up on Orange County beaches last week: the stretch of sand just north of the Newport Pier was carpeted with little bean clams (Donax gouldii) last Wednesday. By Thursday, most of the clams had re-buried in the sand, but Matt went out to take a look and chatted with reporters from CBS … [ Read More ]

December 1, 2016 | Squishy stuff on the beach

These funny little squishy, translucent blobs washed up on Orange County beaches earlier this week, prompting interest and alarm from local beachgoers. After much head scratching and a few wrong turns (nope, they are not salps), Matt and others figured out that they were burrowing sea cucumbers: absolutely harmless, intriguing, and super-cute. Matt was interviewed by and … [ Read More ]

September 6, 2016 | Ph.inally Ph.inisheD.

Congratulations to Kylla Benes! Kylla successfully defended her dissertation today, giving a fantastic presentation about her work to understand intraspecific variation in the seaweed Fucus vesiculosus along tide-height gradients along the coastline of the Gulf of Maine. She melded genetics, physiology, and field experiments to tell a compelling story about how environmental context and dispersal mediate … [ Read More ]

August 9, 2016 | Nutrient uptake by seaweeds

Newly published research by graduate student Kylla Benes highlights the role of tidal elevation and nutrient availability in mediating nitrate uptake by the intertidal seaweed Fucus vesiculosus. In her paper, just out online in the Journal of Phycology, Kylla reports on observations and experiments that describe how acclimation and adaptation to differences in nitrate availability associated with tide height … [ Read More ]

April 18, 2016 | Laura Elsberry receives UCI OCEANS graduate fellowship

Congratulations to Ph.D. student Laura Elsberry! Laura was recently named a member of the inaugural cohort of UCI OCEANS graduate fellows. She received funding to support her research on understanding seaweed species distributions along the California coast.

February 22, 2016 | Understanding the interactions between species in tide pools

Tide pools, like the ones at Corona del Mar State Beach on the Orange County coast, are ideal places to study marine biology. They hold water when the tide is out, allowing animals and marine “plants” – seaweeds and microscopic algae – to live in an otherwise inhospitable environment. The Marine Biodiversity Lab, led by Associate … [ Read More ]

January 7, 2016 | Climate change in tide pools

Our research on warming and CO2 effects in tide pools has just been published in PLoS ONE (Sorte and Bracken 2015). In the paper, we show that warming enhances net community production, but that adding CO2 cancels this increase. Our study, the first field experiment to factorially manipulate warming and CO2 addition in a marine … [ Read More ]

June 1, 2015 | Water quality monitoring

We have been conducting weekly water quality monitoring in the nearshore ocean at Crystal Cove State Park for the past several months. A couple of weeks ago, we decided to assess variability in nutrients, chlorophyll a (a proxy for phytoplankton biomass), pH, and dissolved oxygen over a shorter time-scale. Researchers from the Bracken and Sorte … [ Read More ]

May 7, 2015 | Congrats to Christine Newton-Ramsay!

Christine Newton-Ramsay, who began her Ph.D. work in the Marine Biodiversity Lab in the Fall of 2011, has completed her Ph.D. in record time! Chris came to our lab with a M.S. from the University of Rhode Island and a solid research plan to conduct work on the invasive seaweed Heterosiphonia (now Dasysiphonia) japonica. She wrote and defended … [ Read More ]

December 5, 2014 | Storm effects on terrestrial and marine systems

This past week brought the first real rainfall in Orange County in about 9 months, and the Orange County Register interviewed Matt Bracken and his colleague Travis Huxman (Director of the Center for Environmental Biology and Professor of Ecology and Evolutionary Biology) about effects of the storm on marine and terrestrial ecosystems, respectively. Travis highlighted … [ Read More ]
