“…Moreover, both Noctiluca (Zhang et al, 2017) and M. leidyi (Leonardi, 2020) excrete sticky mucus to trap food, while the surface epithelium of M. leidyi is also covered in mucus (Hammann, 2012). All that material was reported to be readily taken up by heterotrophic marine bacteria (Paliaga et al, 2021;Zhang et al, 2017), indicating a pool of labile OM. On the other hand, when we consider the whole bloom phenomena, for some dinoflagellates, a shift in labile OM was noted only early in the blooming phase and became more refractory toward the final stage (Park et al, 2022), whereas for M. leidyi, the final stage is only reported to add more labile material (Budiša et al, 2022;Condon et al, 2010).…”

Organic matter (OM) properties, assessed with measurements of dissolved and particulate organic carbon (DOC and POC), surface-active DOC (SAS), and DOC normalized surfactant activity (NSA), have been under scrutiny during several recent and notable phenomena along the Adriatic Sea coast in Croatia. These phenomena were (1) massive invasive ctenophore blooms during the summer of 2020 and red tide occurrences in spring 2021 in the northern Adriatic, (2) the formation of the gelatinous macroaggregates in the coastal waters of the central Adriatic during the summer of 2021, and (3) intense autotrophic activity within the water column of the highly stratified and eutrophic marine system of Rogoznica Lake. All these events encompassed single-species plankton blooms characterized by a remarkable increase of OM (up to 320 mg L-1 of DOC and POC) with different surface-active properties (up to 15 mg L-1 of SAS) appearing in the otherwise oligotrophic Adriatic Sea. The NSA, in addition to voltammetric curves with well-defined desorption waves, is a good indicator of the presence of a different type of OM, which can be considered a possible tracer for certain processes in the marine environment. Based on our measurements, a rough threshold value for the OM hydrophobicity-reactivity of NSA = 0.083 is proposed. OM with a value above this threshold is more hydrophobic, as in the case of red tides and gelatinous zooplankton blooms with an average NSA between 0.13 and 0.16. OM with a value below this threshold indicates the presence of more hydrophilic substances such as pollen and OM produced by purple sulfur bacteria.

A first molecular insight into the invasive ctenophore Mnemiopsis leidyi in the northern Adriatic sea

Mnemiopsis leidyi A. Agassiz, 1865 is an invasive ctenophore that has spread to many areas of the Eurasian seas in recent decades and is one of the 100 most dangerous species in the world. This species was first observed in the northern Adriatic Sea in 2005 and then disappeared until 2016, when its first bloom was recorded. After that, it bloomed every summer in the area, causing severe damage to artisanal fisheries. Given the lack of genetic data for the northern Adriatic, here we compare the genetic diversity and phylogenetic relationships of M. leidyi populations sampled in 2016, 2018 and 2021 on the north-eastern coast of Italy with native populations and those introduced in other basins using two molecular markers: CytB and ITS. The CytB haplotype found in the samples from the northern Adriatic was identical to that found in the Gulf of Mexico and the Black Sea/Mediterranean. ITS analysis revealed 11 alleles, including 8 novel ones. The presence of a panmictic population in the northern Adriatic and the lower genetic variability compared to the native populations suggest that M. leidyi has been introduced into the Adriatic more than once and the species recently expanded in this area.
