2. Hydrogeological analysis of topography-driven groundwater flow in a low temperature geothermal aquifer system in the Julian Alps, SloveniaLuka Serianz, Anže Markelj, Nina Rman, Mihael Brenčič, Judit Mádl-Szőnyi, 2025, izvirni znanstveni članek Povzetek: Groundwater flow and heat distribution was investigated in the regional karstic-fissured aquifer-aquitard system near Lake Bled in the Slovenian, eastern Julian Alps. The area features thermal springs with temperatures of 19–23 °C which are exploited by abstraction wells. The occurrence of low-temperature geothermal systems, which are common in the Alps, are associated with specific hydrogeological conditions, such as vertical hydraulic connectivity between different geological formations, relatively large elevation differences along flow paths, and the concentrated upwelling of geothermal water to the surface. The occurrence of the low-temperature geothermal field is explained by the presence of a hydraulically conductive fault along with a regional groundwater flow pattern that supports deep groundwater circulation. Hydraulic measurements and temperature data were collected from springs and wells in the area to support the analysis of flow patterns, together with the construction of a basin-scale 2D numerical flow and heat transport simulation. The diverse topographic and geological conditions result in a multi-scale groundwater flow system. The discharge of thermal waters in the Lake Bled area is a consequence of the upwelling of deep groundwater induced by a combination of the ~ 650 m difference in hydraulic head and hydrogeological heterogeneity and anisotropy, related to faulting of the geological formations. In addition, individual flow subsystems were found to significantly affect the natural heat distribution and travel times within the basin-scale system. The study highlights the combination of a basin scale approach taking into consideration local to regional-scale heterogeneities and faults in order to better understand the hydrogeological behaviour of Alpine groundwater systems.

3. Status of the invasive blue crab Callinectes sapidus Rathbun, 1896 (Brachyura: Portunidae) in SloveniaLovrenc Lipej, Manja Rogelja, 2021, izvirni znanstveni članek Povzetek: Authors present data regarding the presence of the invasive blue crab Callinectes sapidus Rathbun, 1896 (Brachyura: Portunidae) based on records gathered from local fishermen. This alien species was firstly recorded in Slovenian coastal waters in March 2019 and it was subsequently found in six other cases in 2019, 2020 and 2021. Crabs were collected or sighted in shallow coastal areas along the Slovenian coast. In addition, authors discussed about the status of the blue crab in marine and coastal habitats of Slovenia.

5. Interstitial fauna of the Sava River in Eastern SloveniaSimona Prevorčnik, Anja Remškar, Cene Fišer, Boris Sket, Gregor Bračko, Teo Delić, Nataša Mori, Anton Brancelj, Maja Zagmajster, 2019, izvirni znanstveni članek Povzetek: Interstitial water that occupies the pore spaces within unconsolidated sediments is a unique habitat, inhabited by surface as well as exclusively subterranean species (stygobionts). The best studied of all interstitial habitats is the hyporheic zone, an interface between surface water and groundwater (phreatic zone) environments. The Sava River in central Slovenia (i.e., at the Ljubljana alluvial plain) readily qualifies as one of the global hotspots of interstitial biodiversity, while data from other river sections are lacking. In 2015, we sampled two gravel bars on the final Slovenian section of the river (Eastern Slovenia), and collected nine samples per site using the Bou-Rouch pumping method. At »Čatež ob Savi« and »Obrežje« sites, at least 26 invertebrate species with 14 stygobionts and 25 invertebrate species with 13 stygobionts were identified, respectively. Altogether, 33 invertebrate taxa with 16 stygobionts were recorded, which increased the previously known interstitial stygobiotic richness of the Sava River in Slovenia by eight species (to 37 species). Three species of the stygobiotic amphipod genus Niphargus were recorded in Slovenia for the first time, one of which is even a new species to science. We discuss the novel results in the context of current national conservation practices.

6. First confirmation of variegated molehopper Xya variegata (Latreille, 1809) (Orthoptera: Tridactylidae) occuring in SloveniaMatjaž Bedjanič, 2023, drugi znanstveni članki Povzetek: The occurrence of the variegated molehopper Xya variegata in Slovenia is confirmed unambiguously for the first time, based on observations of adults and larvae on 24. 3. 2023 and 2. 6. 2023 on the banks of a gravel pit along the Mura River, east of Petišovci in the Prekmurje region, northeastern Slovenia. Thus, the previously doubtful inclusion of the species in the checklist of Slovenian Orthoptera is now justified. Further research is needed to improve knowledge of its distribution and biology. A detailed assessment of the threat status and planning of conservation measures for this threatened and ecologically highly specialised grasshopper species should also be carried out.

8. Insights into aquifer and borehole thermal energy storage systems for Slovenia’s energy transitionKarlo Borko, Mihael Brenčič, Zdenko Savšek, Jure Knez, Aleš Vozelj, Gregor Kisel, Nina Rman, 2025, izvirni znanstveni članek Povzetek: Since the heating and cooling sectors consume most of the energy in Europe through fossil fuels, the transition to a low-carbon and sustainable energy system is crucial. Underground Thermal Energy Storage (UTES) systems, such as aquifer thermal energy storage (ATES) and borehole thermal energy storage (BTES), offer promising solutions by enabling seasonal storage of renewable thermal energy, balancing the mismatch between supply and demand. ATES and BTES systems store excess heat or cold for later use, making them suitable for large-scale applications like residual heat storage from industrial or power generation processes by offering flexibility in heating and cooling. This review explores the geological and hydrogeological requirements for ATES and BTES systems, pointing out the importance of basic geological knowledge, laboratory and field investigations, and operational monitoring to optimize their performance. The study highlights the need for Slovenia to use the experiences of other European nations to overcome initial challenges, develop effective site evaluation methods, and integrate these systems into existing energy infrastructure.

9. When objects go wandering - lost and found objects from the Skušek collectionHelena Motoh, 2025, izvirni znanstveni članek Povzetek: This paper examines the phenomenon of “wandering objects” through the lens of the Skušek Collection, the largest collection of East Asian objects in Slovenia, which was brought to Ljubljana by Ivan Skušek Jr. and his Japanese wife, Tsuneko Kondō Kawase, in 1920. This collection, which traversed private ownership and eventual institutionali-sation, illustrates the dynamic mobility of artefacts. This study focuses on the movement of these objects both within and outside the family network, exploring how they were dispersed and sometimes reintegrated into the collection. By analysing specific cases, such as the three Japanese screens and other key objects, this paper identifies unique mobility patterns that differ from more common notions of dissociation and “orphaning” in the research of museum collections. The findings highlight the symbolic roles these “wander-ing objects” played in reinforcing social ties and cultural identity. This research contributes to a broader understanding of object mobility and provenance, offering a new conceptual framework for the research of private and institutional collections.
