1. 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, original scientific article Abstract: 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.

2. Paleocoastline modelling – What a difference a few meters of sediment make?Ana Novak, 2024, original scientific article Abstract: Paleoreconstructions of coastal and near-coastal areas have always served as a tool towards better understanding of past, present and future geological and geomorphological processes. The reliability of paleocoastline and sealand extent modelling is controlled by input data. Here the difference between paleoreconstructions based on present-day bathymetry and a paleotopographic elevation model are examined on the example of the Gulf of Trieste (northern Adriatic sea) - a low-gradient submerged Last Glacial Maximum alluvial plain with fairly well-resolved bathymetry and pre-transgressional paleotopography. Results presented in this study show striking differences between the spatial extent of the two modelled sets of paleocoastlines which in places exceeds tens of kilometers. These results demonstrate the importance of using an appropriate geologically-supported elevation model for paleoreconstruction as unsuitable models can result in significant errors and unreliable reconstructions. This is especially noteworthy for low-gradient settings where even a slight variation in sea level can affect vast areas. Finally, the results of this study provide insight into the Early Holocene evolution of the present-day area of the Gulf of Trieste as an abrupt and predominant northeasterly oriented transgression direction is indicated from the paleocoastline reconstructions.

5. Generalization ability of feature-based performance prediction models : a statistical analysis across benchmarksAna Nikolikj, Ana Kostovska, Gjorgjina Cenikj, Carola Doerr, Tome Eftimov, 2024, published scientific conference contribution Abstract: This study examines the generalization ability of algorithm performance prediction models across various bench-mark suites. Comparing the statistical similarity between the problem collections with the accuracy of performance prediction models that are based on exploratory landscape analysis features, we observe that there is a positive correlation between these two measures. Specifically, when the high-dimensional feature value distributions between training and testing suites lack statistical significance, the model tends to generalize well, in the sense that the testing errors are in the same range as the training errors. Two experiments validate these findings: one involving the standard benchmark suites, the BBOB and CEC collections, and another using five collections of affine combinations of BBOB problem instances.

8. Report of the JRCʹs Descriptor 1 workshop to support the review of the Commission Decision 2010/477/EU concerning MSFD criteria for assessing Good Environmental Status : JRC technical reportsL. Avellan, Borut Mavrič, Martina Orlando-Bonaca, 2016, final research report Abstract: The MSFD workshop on biodiversity (MSFD D1), held in Ispra JRC (7th-9th of September 2015) aimed to provide clear proposals and conclusions on some of the outstanding issues identified in the D1 review process and included in the review manual (D1 review version, May 2015: https://circabc.europa.eu/w/browse/46d2b7ba-d2fd-4b3c-9eaf-18c7cb702b53) in support to the review of Commission Decision 2010/477/EU. This report is complementing the Commission Decision 2010/477/EU review manual (JRC96521) and presents the result of the scientific and technical review concluding phase 1 of the review of the Commission Decision 2010/477/EU in relation to Descriptor 1. The review has been carried out by the EC JRC together with experts nominated by EU Member States, and has considered contributions from the GES Working Group in accordance with the roadmap set out in the MSFD implementation strategy (agreed on at the 11th CIS MSCG meeting).

9. Environmental Quality in the Adriatic Ionian Region. Threat to Coastal and Marine Biodiversity : overview and Case Study for IPA Adriatic Balmas and Speedy ProjectsBranko Čermelj, Martina Orlando-Bonaca, Ana Rotter, Boris Petelin, 2016, final research report Abstract: The Environmental Quality is the third thematic pillar of the EU Strategy for the Adriatic and Ionian Region (EUSAIR). The coordinators are Slovenia and Bosnia Herzegovina. The specific objectives of this pillar(EC 2014) (EC, 2014) are:
• to ensure a good ecological and environmental status of the coastal and marine environment by 2020 in line with the relevant EU directives (principally Water Framework Directive (WFD) and Marine Strategy Framework Directive (MSFD)) and the ecosystem approach of the Barcelona Convention;
• to contribute to the goal of the EU Biodiversity Strategy to halt the loss of biodiversity and the degradation of ecosystem services in the EU by 2020, and restore them in so far as feasible, by addressing threats to marine and terrestrial biodiversity; and
• to improve waste management by reducing waste flows to the sea, and to reduce nutrient flows and other pollutants to the rivers and the sea.

10. Čmrlji in čebele samotarke - prezrti opraševalciDanilo Bevk, 2015, other monographs and other completed works Abstract: Kako privabiti divje opraševalce?
Število divjih opraševalcev najlažje povečamo tako, da jim zagotovimo dovolj hrane in varnih mest za gnezdenje. Hrano zagotovimo s sajenjem rastlin, na katerih nabirajo cvetni prah in medičino in z redkejšo košnjo dela travnikov. Pomembno je, da je hrana na razpolago tudi v času, ko kmetijske rastline, ki bi jih želeli opraševati, ne cvetijo. Gnezdilna mesta najlažje zagotovimo z nastavljanjem posebnih gnezdilnic. Pomembno je tudi, da opustimo ali vsaj zmanjšamo uporabo pesticidov. V ustreznem okolju se bodo opraševalci naselili sami in ne bodo zahtevali posebne skrbi.
