“…the area characterized mostly by the northward flux of water of Ionian origin. During the period 1961-2005, in several areas of the eastern Adriatic, changes in phyto-and zooplankton abundance and community structure (Batistić et al, 2007;Conversi et al, 2009;Degobbis et al, 1995;Kamburska and FondaUmani, 2009;Kršinić and Grbec, 2006;Ninčević Gladan et al, 2010), as well as in the quantitative and qualitative composition of the Adriatic ichthyofauna (Dulčić and Grbec, 2000;Lipej and Dulčić, 2004), have been documented and ascribed to natural and man-induced processes. Variations have been observed in biomass (Mozetić et al, 2010;Kamburska and Fonda Umani, 2009), in primary production (Grbec et al, 2009), in taxonomic composition (Ninčević Gladan et al, 2010;Conversi et al, 2009), in life cycles (Kamburska and Fonda Umani, 2009) and in ecosystem functioning (Śolić et al, 2009).…”

Abstract. Analysis of 20-year time-series of the vertically averaged salinity and nutrient data in the Southern Adriatic shows that the two parameters are subject to strong decadal variability. In addition, it is documented that nutrient and salinity variations are out of phase. Nutrients in the Ionian and in the Adriatic vary in parallel except that generally the nutrient content in the Adriatic is lower than in the Ionian, a fact that has been attributed to primary producer consumption following the winter convective mixing. As shown earlier, North Ionian Gyre (NIG) changes its circulation sense on a decadal scale due to the Bimodal Oscillating System, i.e. the feedback mechanism between the Adriatic and Ionian. Cyclonic circulation causes a downwelling of the nitracline along the borders of the NIG and a decrease in the nutrient content of the water flowing into the Adriatic across the Otranto Strait, and vice versa. In addition, the highly oligotrophic central area of the Ionian shows annual blooms only during cyclonic NIG circulation. Inversion of the sense of the NIG results in the advection of Modified Atlantic Water or of the Levantine/Eastern Mediterranean waters in the Adriatic. Here, we show that the presence of allochtonous organisms from Atlantic/Western Mediterranean and Eastern Mediterranean/temperate zone in the Adriatic are concurrent with the anticyclonic and cyclonic circulations of the NIG, respectively. On the basis of the results presented, a revision of the theory of Adriatic ingressions formulated in the early 1950s is proposed.

Consequently, the changes 80 in various biogeochemical parameters may be attributed to these regimes (Dul i et al, 2004; 81 Kršini and Grbec, 2006), including the LIW ingressions and their consequences in the cycle 82 already described. 83…”

The deep sea has long been a mysterious and attractive habitat for protistologists. However, logistical difficulties severely limit sampling opportunities. Consequently, our knowledge of the protists in the deep sea, (arguably the largest habitat on earth), is relatively sparse. Here, we present a unique time‐series concerning three different protist taxa that share only the characteristics of being relatively large, robust to sampling, and easily identifiable to species level using light microscopy: tintinnid ciliates, phaeogromid cercozoans (e.g. Challengerids) and amphisolenid dinoflagellates. We sampled a near‐shore deep water site in the N.W. Mediterranean Sea at 250 m depth over a 2‐yr period at approximately weekly intervals from January 2017 to December 2018. To our knowledge, no previous studies have employed sampling on a similar time scale. We found taxa that appear to be restricted to deep waters, distinct seasonal patterns of abundance in some taxa, and in others nonseasonal successional patterns. Based on data from sampling following a flash flood event, the Challengerid population appeared to respond positively to a pulse of terrigenous input. Some of the distinct mesopelagic tintinnid ciliates and amphisolinid dinoflagellates were also found in two samples from the North Atlantic mesopelagic gathered from near the Azores Islands in September 2018. We conclude that there are a variety of protist taxa endemic to the mesopelagic, that the populations are dynamic, and they may be widely distributed in the deep waters of the world ocean.
