“…The same, i.e. fast consumption of nutrients and restriction of primary production to the coast, has been found around the eastern Adriatic freshwater inputs (Marini et al, 2010;Ninčević Gladan et al, 2010;Viličić et al, 2011). By contrast, the open Adriatic water nutrient load is mostly controlled by the inflowing waters coming from the Ionian Sea (Šolić et al, 2008).…”

Changes in the Adriatic oceanographic properties induced by the Eastern Mediterranean Transient

Abstract. Long-term time series of physical and chemical parameters collected between 1960 and 2010 along the Palagruža Sill transect, Middle Adriatic Sea, have been investigated in terms of average water properties and their variability. Nutrients, especially orthophosphates, reached rather high levels of concentration below the euphotic zone between 1991 and 1998, the highest levels in the investigated period. Simultaneously, the N:P ratio, which is normally higher than 25:1, decreased to values less than 16:1 in the euphotic zone, indicating a switch from typical phosphorus to nitrogen-limited preconditioning for the primary production. Higher-than-usual nutrient levels peaking in the mid1990s, coupled with lower-than-usual temperature, salinity, dissolved oxygen and pH values, are presumably related to the flow of the nutrient richer Western Mediterranean waters to the Adriatic below the euphotic layer. These waters, which keep their footprint in the N:P ratio, enter the Adriatic during the anticyclonic phase of the Bimodal Adriatic-Ionian Oscillation (BiOS), which has been uniquely strengthened by the Eastern Mediterranean Transient occurring in the early 1990s. This hypothesis should be confirmed through targeted research and modelling exercises, as it is highly relevant for the biogeochemistry of the Adriatic Sea.

“…For the southern Adriatic Viličić et al [16] reported a checklist of the phytoplankton community and showed presence of the phytoplankton species. In the southeastern Adriatic, Viličić et al [17] presented influence of Albanian rivers on the nutrients distribution and distribution of phytoplankton and showed dominance of diatoms such as Chaetoceros species (C. circinalis, C. diversus). Caroppo et al [18] presented phytoplankton seasonality in the south-western part of the Adriatic and found that phytoplankton densities show specific oligotrophic water.…”

Distribution of phytoplankton community in Kotor Bay (south-eastern Adriatic Sea)

The goal of this paper was to explain variability of phytoplankton in a shallow coastal area in relation to physico-chemical parameters. Temporal variability and composition of phytoplankton were investigated in the Kotor Bay, a small bay located in the south-eastern part of the Adriatic Sea. Samplings were performed weekly from February 2008 to January 2009 at one station in the inner part of the Kotor Bay, at five depths (0 m, 2 m, 5 m, 10 m, 15 m). Phosphates, nitrites and nitrates ranged from values under the level of detection to the maximum values of 1.54, 1.53 and 23.91 µmol l−1, respectively. The phytoplankton biomass — represented by chlorophyll a concentration — ranged from 0.12 to 6.78 mg m−3, reaching a maximum in summer. Diatoms were present throughout the whole sampling period, reaching the highest abundance in March (3.42×105 cells l−1at surface). The peak of dinoflagellates in July (2.2×106 cells l−1 at surface) was due to a single species, Prorocentrum micans. The toxic dinoflagellate Dinophysis fortii occurred at a concentration of 2140 cells l−1 in May. The present results of phytoplankton assemblages and distribution provide valuable information for this part of the south-eastern Adriatic Sea where data is currently absent.

“…While phytoplankton can directly absorb and use DIP, the absorption rate of organic phosphorus is low. Some phytoplankton may only take up organic phosphorus when inorganic phosphorus is depleted (VILIČIĆ, et al, 2011), and phosphorus de ciency can be directly related to growth and reproduction of phytoplankton and species succession. Under long-term phosphorus limitation conditions, phytoplankton can reduce cellular demand for phosphorus by slowing cell growth (Brembu, et al, 2017;Teikari, et al, 2015;Mohlin and Wulff, 2009), and some phytoplankton also slow phosphorus limitation by increasing cell volume (Li, et al, 2016;Zhang, et al, 2018).…”

Marine phytoplankton size-class structure affects ecological functions and shell sh culture. We use highthroughput sequencing and size-fractioned grading techniques to identify and analyze responses of phytoplankton differences in environmental variables at Donggang, northern Yellow Sea (high inorganic nitrogen (DIN)) and Changhai (low DIN) for 2021. The main environmental variables that correlate with differences in the proportional contributions of pico-, nano-, and microphytoplankton to the total phytoplankton community are inorganic phosphorus (DIP), nitrite to inorganic nitrogen ratio (NO 2 /dissolved inorganic nitrogen (DIN)), and ammonia nitrogen to inorganic nitrogen ratio (NH 4 /DIN), respectively. DIN, which contributes most to environmental differences, mainly positively correlates with changes in picophytoplankton biomass in high DIN waters. Nitrite (NO 2 ) correlates mostly with changes in the proportional contribution of microphytoplankton in high DIN waters and nanophytoplankton in low DIN waters, and negatively correlates with changes in the biomass and proportional representation of microphytoplankton in low DIN waters. For near-shore phosphorus-limited waters, an increase in DIN may increase total microalgal biomass, but proportions of microphytoplankton may not increase; for high DIN waters, an increase in DIP may increase proportions of microphytoplankton, while for low DIN waters, an increase in DIP may preferentially increase proportions of picophytoplankton and nanophytoplankton.Picophytoplankton contributed little to the growth of two commercially cultured lter-feeding shell sh, Ruditapes philippinarum and Mizuhopecten yessoensis.
