Özet

In the present study, Synechococcus spp. pico-, nano- and microplankton communitycompositions in the Arctic and Antarctic surface coastal waters were compared during thesummer of 2019 using flow cytometry. The average surface water temperatures in Antarcticaand the Arctic were −0.29 ± 0.28°C and 3.71 ± 0.71°C, respectively. While planktonabundance in Antarctica exhibited a relative increase with temperature, planktonabundance in the Arctic exhibited a relative decrease with temperature. However, nosignificant correlation was found between plankton abundance and temperature.Synechococcus spp. cell abundance dominated in both polar regions, followed bypicoeukaryotes, microautotrophs and nanoeukaryotes. Overall, plankton abundance acrosssampling sites was highly variable. In Antarctica, the abundance of Synechococcus spp.,picoeukaryotes, nanoeukaryotes and microautotrophs were the highest in S4 (151,400 cells/ml), S1 (2180 cells/ml), S2 (1080 cells/ml) and S4 (6100 cells/ml), respectively. On the otherhand, the most abundant stations in the Arctic in terms of Synechococcus spp.,picoeukaryotes, nanoeukaryotes and microautotrophs were N2 (19600 cells/ml), N3(6400 cells/ml), N3 (500 cells/ml) and N4 (6100 cells/ml), respectively. While Synechococcusspp. and nanoeukaryote abundance were higher in Antarctica, only Synechococcus spp.abundance was significantly higher in Antarctica.
