The coral reef-dwelling Peneroplis spp. shows calcification recovery to ocean acidification conditions
Abstract Large Benthic Foraminifera are a crucial component of coral-reef ecosystems, which are currently threatened by ocean acidification. We conducted culture experiments to evaluate the impact of low pH on survival and test dissolution of the symbiont-bearing species Peneroplis spp., and to obse...
