Sažetak
The microbial phytoplankton community represented by the picocyanobacteria Prochlorococcus and Synechococcus, have an important role in oceanic carbon fixation and nutrient cycling. In this study, the abundance and genetic microdiversity of these two most abundant members of microbial phytoplankton communities was examined during winter cruises conducted in the southern Adriatic Sea (February/March 2015 and March 2016, BIOTA expeditions). Vertical distribution was analyzed within and below the euphotic zone in the South Adriatic Pit as one of the ecologically important Mediterranean hot spots. Abundance and spatial distribution was estimated by flow cytometry and HPLC method, while genetic microdiversity was studied using clone libraries of the 16S-23S ribosomal DNA Internal Transcribed Spacer (ITS) region. This is the first detailed study with focus on the abundance of clades and ecotypes of rich picocynobacterial Prochlorococcus and Synechococcus communities in the South Adriatic Pit.
