A metabarcode based (species) inventory of the northern Adriatic phytoplankton

Lana Grižančić,
Ana Baričević,
Mirta Smodlaka Tanković
et al.

Abstract: The northern Adriatic is characterised as the coldest and most productive marine area of the Mediterranean, which is due to high nutrient levels introduced by river discharges, the largest of which is the Italian Po River (at the same time also the largest freshwater input into the Mediterranean). The northern Adriatic is a very shallow marine ecosystem with ocean current patterns that result in long retention times of plankton in the area. The northern Adriatic phytoplankton biodiversity and abundance are wel… Show more

“…The NA phytoplankton is largely dominated by diatoms, and species from the genera Skeletonema , Pseudo-nitzschia and Chaetoceros are known to be an important component of the NA phytoplankton community with some species occasionally forming very high abundances and toxic blooms 8 , 48 , 54 – 62 . The characterisation of the NA diatom community was mainly studied using classical light microscopy methods for species identification and physiological experiments 8 , 19 , 48 , 61 , 63 while studies using high-throughput sequencing methods of molecular species identification and functional characterisation are still rare for the field 64 66 . Transcriptome and metatranscriptome studies of the diatom community are lacking for the NA.…”

“…Brandtodinium was only recently described as a new dinoflagellate genus [65], and this metabarcoding record represents a new occurrence for the Southern Adriatic. As Brandtodinium has only recently also been metabarcoded for the northern Adriatic [24], this may indicate a wider and more common occurrence in the Adriatic that was previously hidden due to microscopic identification limitations. While species of the genus Eucyrtidium have been described in previous studies as characteristic of the euphotic layer in the Southern Adriatic [66], the genera Sphaerozoum (Sphaerozoum trigenimum and Sphaerozoum fuscum), Disolenia (Disolenia quadrata) and Collozoum (Collozoum sp.)…”

“…In addition to Brandtodinium (Brandtodinium nutricula), Pelagodinium (Pelagodinium beii) as a foraminifera symbiont [65,69] and Ellobiopsis (Ellobiopsis chattonii) as a common parasite of pelagic marine copepods (Acartia, Calanus, Centropages) [70] were recorded for the first time in the Southern Adriatic. As Pelagodinium has only recently been metabarcoded for the Northern Adriatic [24], its detection in the Southern Adriatic may indicate a broader and more common occurrence in the Adriatic, which was previously hidden due to microscopic identification limitations. Blastodinium, Syndinium and Chytriodinium are cosmopolitan genera of parasitic dinoflagellates, also known as copepod parasites in the gut or lipid-rich copepod eggs [71,72].…”
