1. New Mediterranean biodiversity records (July 2018)Niki Chartosia, Dimitris Anastasiadis, Hocein Bazairi, Fabio Crocetta, Alan Deidun, Marija Despalatović, Vincenzo di Martino, Nikos Dimitriou, Branko Dragičević, Jakov Dulčić, Furkan Durucan, Deniz Hasbek, Vlasios Ketsilis-Rinis, Periklis Kleitou, Lovrenc Lipej, Armando Macali, Agnese Marchini, Mariam Ousselam, Stefano Piraino, Bessy Stancanelli, Marilena Theodosiou, Francesco Tiralongo, Valentina Todorova, Domen Trkov, Sercan Yapici, 2018, izvirni znanstveni članek Povzetek: In the present article, new records are given for 15 species (4 native and 9 alien and 2 cryptogenic), belonging to 6 Phyla (i.e. Chlorophyta, Ctenophora, Cnidaria, Mollusca, Arthropoda, and Chordata), from 10 Mediterranean countries: Morocco: the finding of the crab Callinectes sapidus represents the westernmost one of the species in the Mediterranean; Italy: first records of the nudibranch Polycera hedgpethi from the harbour of La Spezia, and first finding of the invasive ctenophore Mnemiopsis leidyi in the Fiora River; Tunisia: Caulerpa taxifolia var. distichophylla is recorded for the first time, showing an even wider distribution in the Mediterranean; Greece: the finding of the jellyfish Pelagia benovici represents the first record of the species in the Ionian Sea, while the finding of the smallscale codlet Bregmaceros nectabanus in the Ionian Sea is another interesting first report for the area; Malta: the cryptogenic scleractinian coral Oculina patagonica was recorded; Slovenia: the parasitic copepod Demoleus heptapus was recorded from a sixgill bluntnose shark, Hexanchus griseus; Croatia: the Lessepsian cephalaspidean mollusc Haminoea cyanomarginata is recorded for the first time from the area; Bulgaria: the Asian date mussel Arcuatula senhousia was recorded from the Black Sea; Cyprus: the Lessepsian gastropod Viriola sp. [cf. corrugata) was recorded for the first time from the area, while two decapod species were recorded also for the first time from Cyprus, i.e. the caridean shrimp Pasiphaea sivado and the anomuran Munida curvimana; Turkey: the acari Lohmannella falcata is recorded for the first time from Antalya and the Lessepsian fish Priacanthus sagittarius in the Levantine coasts of Turkey (off Hatay/Arsuz) showing that this species has extended its range in a very short time.

2. Marine strategy framework directive : Descriptor 2, non - indigenous species delivering solid recommendations for setting threshold values for non-indigenous species pressure on European seasKonstantinos Tsiamis, Ivan Cvitković, Marija Despalatović, Branko Dragičević, Jakov Dulčić, Ana Fortič, Janja Francé, Lovrenc Lipej, Borut Mavrič, Patricija Mozetič, Živana Ninčević Gladan, Martina Orlando-Bonaca, Monika Peterlin, Valentina Pitacco, Domen Trkov, Olja Vidjak, Ante Žuljević, 2021, končno poročilo o rezultatih raziskav Povzetek: Marine Non-Indigenous Species (NIS) are animals and plants introduced accidently or deliberately into the European seas, originating from other seas of the globe. About 800 marine non-indigenous species (NIS) currently occur in the European Union national marine waters, several of which have negative impacts on marine ecosystem services and biodiversity. Under the Marine Strategy Framework Directive (MSFD) Descriptor 2 (D2), EU Member States (MSs) need to consider NIS in their marine management strategies. The Descriptor D2 includes one primary criterion (D2C1: new NIS introductions), and two secondary criteria (D2C2 and D2C3). The D2 implementation is characterized by a number of issues and uncertainties which can be applicable to the Descriptor level (e.g. geographical unit of assessment, assessment period, phytoplanktonic, parasitic, oligohaline NIS, etc.), to the primary criterion D2C1 level (e.g. threshold values, cryptogenic, questionable species, etc), and to the secondary criteria D2C2 and D2C3. The current report tackles these issues and provides practical recommendations aiming at a smoother and more efficient implementation of D2 and its criteria at EU level. They constitute a solid operational output which can result in more comparable D2 assessments among MSs and MSFD regions/subregions. When it comes to the policy-side, the current report calls for a number of different categories of NIS to be reported in D2 assessments, pointing the need for the species to be labelled/categorised appropriately in the MSFD reporting by the MSs. These suggestions are proposed to be communicated to the MSFD Working Group of Good Environmental Status (GES) and subsequently to the Marine Strategy Coordination Group (MSCG) of MSFD. Moreover, they can serve as an input for revising the Art. 8 Guidelines.

3. On the occurrence of early life stage of the king of herrings, Regalectus glesne (Actinopterygii: Lampriformes: Regalectidae), in the Adriatic SeaBranko Dragičević, Armin Pallaoro, Robert Grgičević, Lovrenc Lipej, Jakov Dulčić, 2011, drugi znanstveni članki Povzetek: The occurrence of an early life stage of the king of herrings, Regalecus glesne Ascanius, 1772, is reported for the first time from the Adriatic waters. A single larva (SL = 103.4 mm) was found alive in the waters of open Adriatic near a remote Island PalagruĹľa. Findings of early life stages of this species are very rare in the Mediterranean and have previously been reported only from the waters of the Strait of Sicily and Elba Island.

4. First substantiated record of a lessepsian migrant - the dusky spinefood, Siganus luridus (Actinopterzgii: Perciformes: Siganidae), in the Adriatic SeaJakov Dulčić, Branko Dragičević, Robert Grgičević, Lovrenc Lipej, 2011, drugi znanstveni članki Povzetek: One specimen of the dusky spinefoot, Siganus luridus (Rüppell, 1829) (+, total length = 17.3 cm, total weight = 87.61 g), a lessepsian migrant, was captured in the Mljet Channel (Southern Adriatic, Croatian coast) on 15 November 2010. This is the second record of this species from the Adriatic, but first well documented and based on the captured specimen. First record occurred earlier in the Northern Adriatic, but was based solely on underwater observations.

5. First record of the meagre, Argyrosomus regius (Asso, 1801), in Slovenian coastal waters with additional records from the Croatian part of the Adriatic SeaBorut Mavrič, Branko Dragičević, 2018, izvirni znanstveni članek Povzetek: One specimen of meagre, Argyrosomus regius (Asso, 1801), was caught by trawling in the waters off Slovenia on 24th November 2016 at the depth of cca. 20 m above sandy-muddy bottom. This is the fi rst record of this species for the Slovenian part of the Adriatic Sea. Due to the fact that there are no wild populations in the Middle and North Adriatic and that remaining wild populations in the Southern Adriatic are scarce and small, the specimen is supposed to be an escapee from one of the mariculture facilities. Additional occurrences of this species from the Croatian part of the Adriatic Sea are reported.

6. New alien Mediterranean biodiversity records (August 2022)Francesco Tiralongo, Okan Akyol, Sara A. A. Al-Mabruk, Pietro Battaglia, Damla Beton, Banu Bitls, John Joseph Borg, Marc Bouchoucha, Melih Ertan Çinar, Fabio Crocetta, Branko Dragičević, Jakov Dulčić, Athanasios Evangelopoulos, Julian Evans, Ana Fortič, Robin P. M. Gauff, Constantinos Georgiadis, Mehmet Gökoğlu, Daniele Grech, Tamar Guy-Haim, Mehmet Fatih Huseyinoglu, Domen Trkov, 2022, izvirni znanstveni članek Povzetek: In this Collective Article on alien and cryptogenic diversity in the Mediterranean Sea we report a total of 19 species belonging to nine Phyla and coming from nine countries. Several of these records concern fish species, and of particular interest are the first records of: Terapon puta for Italian waters; Pteragopus trispilus from Malta; Plotosus lineatus from Cyprus; and the northernmost Mediterranean record of Lagocephalus sceleratus. The northernmost Mediterranean record was also reported for the sea urchin Diadema setosum. The portunid crab Thalamita poissonii was recorded for the first time in Libya. The copepod Pseudodiaptomus marinus was recorded for the first time in the Marmara Sea. The polychaete Branchiomma luctuosum was recorded for the first time from the Mediterranean coast of France. The alien anemone Diadumene lineata was recorded for the first time from Slovenia. The macroalgae Sargassum furcatum was recorded for the first time from Italy. The new Mediterranean records here reported help tracing abundance and distribution of alien and cryptic species in the Mediterranean Sea.
