1. Faunistic, ecological, and zoogeographical survey of heterobranch fauna in the Adriatic Sea: experiences from SloveniaLovrenc Lipej, Ana Fortič, Domen Trkov, Borut Mavrič, Danijel Ivajnšič, 2025, izvirni znanstveni članek Povzetek: The heterobranch fauna recorded to date in the Slovenian part of the Adriatic Sea was reviewed and analysed in order to present an updated inventory. The ecological traits and zoogeographical affiliation of the recorded heterobranchs were also analysed. The new data revealed that the heterobranch fauna in the area consists of at least 157 species with the majority being nudibranchs (61.4%). The bulk of heterobranchs were considered as Atlanto-Mediterraneans. Heterobranch diversity was found to be significantly related to the number of sampling events. The spatial pattern of heterobranch species and their composition structure in parts of the study area were linked to specific human-impacted areas (HIAs) such as coastal wetlands, ports, and mariculture facilities. Better examination of less investigated environments, new sampling techniques, and citizen science involvement will doubtlessly increase the numbers in this checklist.

2. An insight into the heterobranch fauna of Fiesa (Slovenia, northern Adriatic Sea)Tea Knapič, Irena Frkovič, Borut Mavrič, Lovrenc Lipej, 2024, izvirni znanstveni članek Povzetek: The authors investigated the marine heterobranch fauna (Heterobranchia, Gastropoda) in Fiesa, a tourist destination and one of the most popular diving sites in the Gulf of Trieste (northern Adriatic Sea). Specimens of heterobranchs were collected during sporadic sampling between November 2021 and January 2022. A total of 30 species from 6 higher taxa (Cephalaspidea 1, Aplysiida 1, Umbraculida 1, Sacoglossa 3, Pleurobranchida 2, Nudibranchia 22) were recorded and identified. Including previously published and recorded data, the total number of species currently known in the study area has increased to 51. Future surveys, involving additional sampling methods and carried out during other seasons of the year, are expected to further increase the number of recorded marine heterobranch species inhabiting the area.

3. An annotated checklist and the conservation status of Chondrichthyans in the AdriaticAlen Soldo, Lovrenc Lipej, 2022, izvirni znanstveni članek Povzetek: Although there is a high number of publications listing fish species in the Adriatic, only a few have focused on chondrichthyans, while their conservation status has been investigated even less. Thus, this paper aims to provide an updated and annotated checklist of the chondrichthyans occurring in the Adriatic waters with their presence and conservation status. Each species is evaluated against the criteria defined in IUCN (International Union for Conservation of Nature) Red List Categories and Criteria and according to the guidelines for national and regional level assessments. In total, 60 chondrichthyan species from 27 families and 42 genera are listed. The list contains 33 species of sharks, 26 species of rays and one chimera. Assessment of the conservation status reveals that three species are now considered Regionally Extinct (namely Squatina oculata, Pristis pectinata and Rhinobatos rhinobatos). A total of 21 species are assessed as Critically Endangered, 8 are Endangered and 10 are Vulnerable. Of the remaining species, six are Near Threatened and the same number of species are Least Concern and Data Deficient. Considering that the principal driver of chondrichthyan decline and regional extinction is overfishing, it is recommended that the Adriatic countries adopt the same management measures and strengthen their coordination.
