Ocean acidification caused abundance loss in residential zooplankton living within coral reefs
Most of what is known about the effects of ocean acidification on zooplankton relates to a few species composed of calcium carbonate, or comes from laboratory and mesocosm studies that observe a relatively small number of species, primarily copepods. So far little is known about how entire zooplankt...
