3. Dasysiphoniaadriatica sp. nov. (Delesseriaceae, Rhodophyta), a new red algal species from the North Adriatic Sea (Mediterranean Sea)Marion Adelheid Wolf, Katia Sciuto, Alessandro Buosi, Martina Orlando-Bonaca, Ana Fortič, Adriano Sfriso, 2024, izvirni znanstveni članek Povzetek: Dasysiphonia is a genus of the family Delesseriaceae (Rhodophyta) including 9 taxonomically accepted species, among which only the non-indigenous Dasysiphonia japonica has been documented from the Adriatic Sea (Mediterranean). This invasive spe-cies is native to Hokkaido Island (Japan) and was introduced to Europe and the Mediterranean Sea through imports of the com-mercial Pacific oyster Magallana gigas. In this study, we describe a new species belonging to the genus Dasysiphonia, collected in the Mediterranean Sea. This new taxon was sampled in Slovenian coastal waters; its thalli were analysed using both molecular and morphological approaches and it was compared with the other known species. Moreover, samples of the invasive D. japonicawere collected from different Venice Lagoon (Italy) sites and used for comparison with the new taxon. The phylogenetic recon-struction, based on the plastid rbcL gene, clearly distinguished the new Slovenian entity from all the known Dasysiphonia species, including the ones recently transferred from the sister genus Dasya. These results indicate that the Slovenian samples represent a new species, hereby named Dasysiphonia adriatica sp. nov.

5. 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.

6. Establishing thresholds : workshop on the MSFD Newly Introduced NIS (D2C1)Chiara Magliozzi, C. Bartilotti, A. Botelho, M. Bugeja, João Canning-Clode, Ana Fortič, Martina Orlando-Bonaca, 2023, končno poročilo o rezultatih raziskav Povzetek: The Workshop on ‘Establishing thresholds: workshop on the Marine Strategy Framework Directive (MSFD) Newly Introduced Non-Indigenous Species (NIS) (D2C1)’ took place online on the 24th November 2022, aiming at discussing and making progress towards establishing threshold values for the criterion D2C1. The workshop was organised by the Joint Research Centre (JRC), in collaboration with representatives of the Regional Sea Conventions (RSCs), under the MSFD Descriptor 2 Core Group, in the context of the MSFD Common Implementation Strategy Good Environmental Status Working Group. The participants to the workshop included academic and public authorities’ experts on MSFD NIS, RSCs representatives, the European Environment Agency (EEA), and Commission services. The workshop enabled sharing information on the state-of-the-art approaches on monitoring and assessment of D2C1 within Regional Seas and on the application of the time series analysis as a follow-up to Tsiamis et al. (2021) recommendations for setting threshold values. The discussion focused on ensuring comparability of approaches, how to account for uncertainties, and on areas for improvement. It was acknowledged that activities of RSCs are instrumental in coordinating the science and management of marine NIS. The various levels of monitoring across the North-East Atlantic Ocean, the Mediterranean Sea, the Baltic Sea and the EU Countries explain different methodological approaches for setting thresholds, while the limited monitoring restrict the application of these methodologies in the Black Sea. The workshop identified four main areas for improvements: i) establishment of acknowledged baselines for NIS introductions, ii) make further progress in monitoring and analysis methods, iii) agree on thresholds for new NIS introductions and, iv) ensure coherence and consistency between national and regional reports. The JRC will seek for opportunities to discuss and advance on identified areas for improvement with the MSFD national appointed NIS experts The MSFD Descriptor 2 (D2) Core Group will contribute to the discussions.

7. First record of the bryozoan Tricellaria inopinata (dʼHondt & Occhipinti Ambrogi, 1985) from the Slovenian seaAna Fortič, Borut Mavrič, 2018, drugi znanstveni članki Povzetek: In this paper we present the first record of Tricellaria inopinata d’Hondt & Occhipinti Ambrogi, 1985 for the Slovenian coastal sea. The colonies of this bryozoan were found attached to the mussel shells in the sight of Sečovlje, Strunjan and Debeli rtič mussel cultures from April to October 2018 and in Valdoltra harbour in November 2018. After the introduction into the Lagoon of Venice in the 1980s and its rapid spread throughout the lagoon in the following years, the species was regarded as an invasive taxon for that area and it is highly expected to colonize the whole Northern Adriatic region. The status of T. inopinata and its ecological impact has yet to be determined for the Slovenian coastal sea.

8. First record of the Canestrini’s goby Ninnigobius canestrinii (Ninni, 1883) : a rare and endangered fish species from Slovenian watersDomen Trkov, Ana Fortič, 2023, drugi znanstveni članki Povzetek: The Canestrini’s goby is a small goby endemic to the Adriatic basin, inhabiting brackish and fresh waters. The species is threatened by habitat destruction and pollution. For this reason, the goby is protected in part of its range, while its conservation status in other areas is not yet established. The detailed biogeography of the species should be known so that appropriate conservation measures can be taken. Despite extensive sampling of fish fauna in coastal wetlands, this species has not yet been detected in Slovenia. In this study, the first record of Ninnigobius canestrinii (Ninni, 1883) in Slovenian waters is reported along with a comprehensive review of documented records of the species.

Through this effort, we collected and harmonized a dataset of 12,649 records. It includes 247 taxa, of which 217 are Animalia, 25 Plantae and 5 Chromista, from 23 countries surrounding the Mediterranean and the Black Sea. Chordata was the most abundant taxonomic group, followed by Arthropoda, Mollusca, and Annelida. In terms of species records, Siganus luridus, Siganus rivulatus, Saurida lessepsianus, Pterois miles, Upeneus moluccensis, Charybdis (Archias) longicollis, and Caulerpa cylindracea were the most numerous. The temporal distribution of the records ranges from 1973 to 2022, with 44% of the records in 2020–2021. Lethrinus borbonicus is reported for the first time in the Mediterranean Sea, while Pomatoschistus quagga, Caulerpa cylindracea, Grateloupia turuturu, and Misophria pallida are first records for the Black Sea; Kapraunia schneideri is recorded for the second time in the Mediterranean and for the first time in Israel; Prionospio depauperata and Pseudonereis anomala are reported for the first time from the Sea of Marmara. Many first country records are also included, namely: Amathia verticillata (Montenegro), Ampithoe valida (Italy), Antithamnion amphigeneum (Greece), Clavelina oblonga (Tunisia and Slovenia), Dendostrea cf. folium (Syria), Epinephelus fasciatus (Tunisia), Ganonema farinosum (Montenegro), Macrorhynchia philippina (Tunisia), Marenzelleria neglecta (Romania), Paratapes textilis (Tunisia), and Botrylloides diegensis (Tunisia).

10. New evidence of the occurrence of Knoutsodonta Pictoni (Nudibranchia, Onchidorididae) in the Northern AdriaticAna Fortič, Domen Trkov, Lovrenc Lipej, Marco Fantin, Saul Ciriaco, 2021, izvirni znanstveni članek Povzetek: The authors present new data on the recently described nudibranch Knoutsodonta pictoni Furfaro & Trainito, 2017 in the Gulf of Trieste (northern Adriatic Sea). We hereby present the first record of this species in Slovenian territorial waters. A total of 22 specimens of K. pictoni were recorded by diving in the period from 2017 to 2021 at five localities in the Gulf of Trieste. All specimens were found in precoralligenous habitats in the depth range of 5 to 9 m, feeding on the encrusting bryozoan Reptadeonella violacea (Johnston, 1847). Numerous finds indicate that this only recently described and therefore little known nudibranch is much less rare than previously thought.
