Near future ocean acidification increases growth rate of the lecithotrophic larvae and juveniles of the sea star Crossaster papposus
Abstract Ocean acidification (OA) is believed to be a major threat for near‐future marine ecosystems, and that the most sensitive organisms will be calcifying organisms and the free‐living larval stages produced by most benthic marine species. In this respect, echinoderms are one of the taxa most at...
