Coccolithophorida: Species diversity in the Northern Adriatic

The coccolithophorida are calcifying, unicellular eukaryotes that form an important part of the marine phytoplankton. They belong to the algal division Haptophyta. Two life-cycle phases, haploid and diploid, alternate within Haptophyta and the transition between them is prompted by environmental triggers. Each phase is characterised by different types of coccoliths, the holococcoliths and heterococcoliths. These were so different, that each phase was first described and named as separate species. Species diversity was analysed in the coastal area of the northern Adriatic, 1 nm in front of Rovinj. Samples were taken over a one year period every ten days, thus covering the observable range of species throughout the succession time line. The primary data source used in this study was scanning electron microscopy. A total of 31 species were recorded, 4 of which were observed in both life-cycle stages (Syracosphaera pulcha (HOL Calyptrosphaera oblonga), Syracosphaera histrica (HOL Calyptrolithophora papillifera), Helicosphaera carteri (HOL Syracolithus catilliferus) and Coronosphaera mediterranea (HOL Calyptrolithina wettsteini)). The genus with the most species present was Syracosphaera, represented by 10 species. An unexpectedly wide diversity of coccolithophorida was recorded. Our results dramatically change the perception of the importance of coccolithophorida for the northern Adriatic phytoplankton.
