1. A FAIR perspective on data quality frameworksNicholas Nicholson, Raquel Negrão Carvalho, Iztok Štotl, 2025, izvirni znanstveni članek Povzetek: Despite considerable effort and analysis over the last two to three decades, no integrated scenario yet exists for data quality frameworks. Currently, the choice is between several frameworks dependent upon the type and use of data. While the frameworks are appropriate to their specific purposes, they are generally prescriptive of the quality dimensions they prescribe. We reappraise the basis for measuring data quality by laying out a concept for a framework that addresses data quality from the foundational basis of the FAIR data guiding principles. We advocate for a federated data contextualisation framework able to handle the FAIR-related quality dimensions in the general data contextualisation descriptions and the remaining intrinsic data quality dimensions in associated dedicated context spaces without being overly prescriptive. A framework designed along these lines provides several advantages, not least of which is its ability to encapsulate most other data quality frameworks. Moreover, by contextualising data according to the FAIR data principles, many subjective quality measures are managed automatically and can even be quantified to a degree, whereas objective intrinsic quality measures can be handled to any level of granularity for any data type. This serves to avoid blurring quality dimensions between the data and the data application perspectives as well as to support data quality provenance by providing traceability over a chain of data processing operations. We show by example how some of these concepts can be implemented at a practical level.

4. Genetic assignment at different geographical levels : a case study in a forest tree species (Pinus pinaster Ait.) using SNP markersSanna Olsson, Delphine Grivet, Marjana Westergren, Santiago C. González-Martínez, Ricardo Alía, Juan José Robledo-Arnuncio, 2025, izvirni znanstveni članek Povzetek: Genetic markers can assist in the identification of the stock origin in different organisms. Comparative studies of forest tree provenances have demonstrated that forest tree populations differ in performance across environments and at multiple geographic levels: populations nested within regions nested within gene pools. These levels are critical for conservation and sustainable use of genetic resources: regions of provenance are key units for seed marketing, while populations guide reproductive material collection under most seed regulations. Despite their potential, genetic methods have rarely been applied to identify forest tree origins due to methodological (sufficient number of highly discriminatory markers) and practical (construction of a baseline composed of a representative selection of samples) challenges. In our study, we analyzed a genomic dataset comprising 10,185 SNPs from 1579 samples of Pinus pinaster, a species with strong population structure, across 86 populations, 45 regions of provenance, and 10 gene pools, to discriminate among these hierarchical levels and assign individuals to them. We used two software packages to evaluate the reliability of our baseline dataset (i.e., reference data) for genetic discrimination and assignment: RUBIAS, which performs genetic stock identification and associated tasks, and assignPOP, implementing a supervised machine-learning genetic-assignment framework. Using numerical validation analyses, we assessed their suitability and limitations for origin inference at each geographical level. Our results indicate that origin assignment is reliable in P. pinaster at the gene pool and region of provenance levels, but less so at the population level, provided that the 10 K SNP markers and a comprehensive genetic baseline are used. Incomplete baselines may result in wrong assignments at any hierarchical level, irrespective of sampling intensity for sampled candidate origins. We provide an extensive and publicly available baseline for P. pinaster, offering a useful tool for the management of forest genetic resources of this economically and ecologically important tree species.

5. 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.

6. The onset of Pliocene – Early Pleistocene fluvial aggradation in the Southeastern Alpine Foreland (Velenje Basin, Slovenia) and its paleoenvironmental implicationsEva Mencin Gale, Petra Jamšek Rupnik, Naki Akçar, Marcus Christl, Christof Vockenhuber, Flavio S. Anselmetti, Andrej Šmuc, 2024, izvirni znanstveni članek Povzetek: In this study, we focused on the Pliocene–Early Pleistocene fluvial terraces in the Velenje Basin andreconstructed the morphostratigraphy, sedimentary depositional environment, provenance and age of the graveldeposits using geomorphological, sedimentological, petrographic and chronological analyses. Geomorphologicalmapping revealed the presence of two main river‐terrace groups. The terraces in the older terrace group are severelydegraded and preserved only as remnants capping high ground, while in contrast the younger group is betterpreserved. Detailed lithofacies analyses of four selected stratigraphic sections of the older terrace group show that thegravel was deposited in a meandering and wandering environment. The gravel consists of metamorphic, igneous,volcaniclastic, clastic and carbonate lithologies derived from the north, east and west from the Paka Rivercatchments. To determine the timing of deposition, we performed isochron‐burial dating using cosmogenic 26Al and10 Be. Our new age constraints date the deposition of the older terrace group to 2.7 ± 0.3 Ma. Establishing theaggradation and incision model of the Velenje Basin documents pronounced regional tectonic uplift during thePliocene–Early Pleistocene, which led to incision and the subsequent formation of a terrace staircase.

7. How beech provenance affects the structure of secondary xylem, leaf traits, and the ectomycorrhizal community under optimal growth conditionsTanja Mrak, Jožica Gričar, Tina Unuk Nahberger, Gregor Božič, Luka Krajnc, Peter Prislan, Domen Arnič, Tom Levanič, Hojka Kraigher, 2024, izvirni znanstveni članek Povzetek: Beyond growth parameters and drought tolerance, comparatively little is known about the functioning of different beech (Fagus sylvatica L.) provenances. We investigated properties of leaves, stem secondary xylem, and ectomycorrhiza (ECM), and explored their interdependencies to identify the best performing beech provenance in optimal growth conditions. The study was conducted on 23-year-old trees in a provenance trial. The investigated provenances originated from Atlantic (Belgium—BE), Alpine (Italy—IT, Slovenia—SI), and continental climates (the Czech Republic—CZ). A significant effect of provenance was observed for stem vessel diameters and conductive area, as well as for foliar %C, δ13C, δ15N, and δ18O. δ13C as a proxy of intrinsic water use efficiency (iWUE) showed that the highest iWUE was achieved in BE provenance. Individuals with a better iWUE had wider growth rings regardless of provenance. Better iWUE was associated with lower specific leaf area (SLA). ECM community composition and diversity indices did not differ significantly among the provenances. Specific ECM taxa were associated with individuals with high SLA, δ13C, δ15N, and δ18O. In optimal growth conditions with no stress events, BE is a promising provenance due to an efficient water conducting system with high vessel diameters and conductive area, and high iWUE, while Alpine provenances showed an adaptation of their water conducting system to freezing conditions at their original locations. Integrating findings from different compartments improves our understanding of functioning of different beech provenances.

9. Geochemical and mineralogical approaches in unraveling paleoweathering, provenance, and tectonic setting of the clastic sedimentary succession (Western Central Paratethys)Kristina Ivančič, Rok Brajkovič, Mirijam Vrabec, 2024, izvirni znanstveni članek Povzetek: Pronounced tectonic and paleogeographic changes were detected in the Alpine–Pannonian region during the Miocene at the interface between the Alps, the Dinarides, and the Pannonian Basin. To understand the major tectonic, paleogeographic, and paleoclimatic changes during this period, geochemical and mineralogical investigations were carried out on the fine-grained clastic sedimentary rocks in the Tunjice Hills. The paleoweathering indicates a cold and/or arid to a warm and humid period. The paleoclimate and the regional climatic conditions correspond well with the Middle Miocene Climatic Optimum. The mineral composition shows an abundance of quartz and calcite. Quartz is associated with detrital origin from volcanic and metamorphic rocks of the Eastern and Southern Alps and with authigenic processes in sediments. Calcite is related to authigenic origin formed in shallow marine environments and to detrital provenance from the Southern Alps. Not all discriminant functions based on major oxides provided adequate results in determining the tectonic setting. The source rocks were subjected to oceanic island arc and collision. Moreover, sedimentation was influenced by both active and passive margin settings. The former is related to the Alpine collision, which continued from the Cenozoic onward, and the latter is connected to the processes associated with the formation of the Pannonian Basin System, which began in the late Early Miocene.

10. Raman microspectroscopy of garnets from Sfibulae from the archaeological site Lajh (Slovenia)Saša Kos, Matej Dolenec, Judita Lux, Sabina Dolenec, 2020, izvirni znanstveni članek Povzetek: Garnets (19 pieces) of Late Antique S-fibulae from the archaeological site at Lajh-Kranj (Slovenia) were analysed with Raman microspectroscopy to obtain their mineral characteristic, including inclusion assemblage. Most garnets were determined as almandines Type I of pyralspite solid solution series; however, three garnets showed a higher Mg, Mn and Ca contents and were determined as almandines Type II. Most significant Raman bands were determined in the range of 169–173 cm−1 (T(X2+)), 346–352 cm−1 (R(SiO4)), 557–559 cm−1 (ν2), 633–637 cm−1 (ν4), 917–919 cm−1 (ν1), and 1042–1045 cm−1 (ν3). Shifting of certain Raman bands toward higher frequencies was the result of an increase of the Mg content in the garnet composition, which also indicates the presence of pyrope end member in solid garnet solutions. Inclusions of apatite, quartz, mica, magnetite, ilmenite, as well as inclusions with pleochroic or radiation halo and tension fissures (zircon), were found in most of the garnets. Rutile and sillimanite were found only in garnets with the highest pyrope content. Spherical inclusions were also observed in two garnets, which may indicate the presence of melt or gas residues. The determined inclusion assemblage indicates the formation of garnets during medium- to high-grade metamorphism of amphibolite or granulite facies. According to earlier investigations of the garnets from Late Antique jewellery, the investigated garnets are believed to originate from India.
