Coccolithophorids in Polar Waters: Mercedesia gen. nov., Ericiolus, Quaternariella and Porsildia gen. nov.
Coccolithophorid samples from arctic and antartic regions have been examined for an update on species morphology, life history aspects and biogeography for the coccolithophorid genera Ericiolus and Quaternariella and two other genera here described as new. Mercedesia gen. nov. comprises three new sp...
