Scientists analyzed the carbon composition in Seaside Sparrow tissues to learn if oil from the 2010 spill was incorporated into the terrestrial food web. The researchers found reduced radiocarbon and stable carbon concentration levels in the feathers of birds captured at oiled sites compared with birds from non-oiled sites, which is consistent with a fossil Read More

GoMRI StudentsPublication Highlights Study Finds UV Exposure Late in Mahi-Mahi Embryo Development Enhances Oil Toxicity Ph.D student Jason Magnuson collects embryos at the University of Miami RSMAS. Photo provided by RECOVER.

Researchers conducted laboratory experiments on mahi-mahi embryos to determine the effects of ultraviolet radiation (UV) and oil co-exposure during different times in their development. The team observed that UV affected the success of mahi-mahi hatch in all exposure scenarios compared to controls but was highest (a 1.6- to 6-fold increase) when co-exposure occurred late in Read More

GoMRI ScientistsPublication Highlights Study Identifies Key Species that Influence Marsh Ecosystem Responses to Oiling The authors created a salt marsh food web with oil sensitivity ratings for each species or node. Clear circles indicate no data available. Blue, yellow, and red circles depict sensitivity scores of 0, 1, and 2, respectively. Nodes are arranged so that trophic level increases vertically.

Scientists constructed a food web model using data from published studies and their field experiences to understand how specific Louisiana salt marsh organisms influenced ecosystem response to the Deepwater Horizon oil spill. The researchers found that carnivorous fishes were “critically resilient” and likely enhanced food web resilience. Gulls, terns, omnivorous snails, and wading birds were “critically sensitive” Read More
