Ocean acidification makes it harder for sea snails to escape from their sea star predators, according to a study from the University of California, Davis.The findings, published in the journal Proceedings of The Royal Society B, suggest that by disturbing predator-prey interactions, ocean acidification could spur cascading consequences for food web systems in shoreline ecosystems.For instance, black turban snails graze on algae. If more snails are eaten by predators, algae densities could increase."Ocean acidification can affect individual marine organisms along the Pacific coast, by changing the chemistry of the seawater," said lead author Brittany Jellison, a Ph.D. student studying marine ecology at the UC Davis Bodega Marine Laboratory.
