Systematics and evolutionary history of raft and nursery-web spiders (Araneae: Dolomedidae and Pisauridae)
Kuang-Ping Yu, Ren-Chung Cheng, Charles R. Haddad, Akio Tanikawa, Brogan L. Pett, Luis N. Piacentini, Ho Yin Yip, Yuya Suzuki, Arnaud Henrard, Christina J. Painting, Cor J. Vink, Eileen A. Hebets, Mark S. Harvey, Matjaž Kuntner, 2025, zaključena znanstvena zbirka raziskovalnih podatkov

Povzetek: Pisauridae are a global and heterogeneous assemblage of spider genera with diverse morphologies and lifestyles. So far, the monophyly of Pisauridae and the inclusion of fishing spiders (Dolomedes) in this family have not been thoroughly tested. Here, we amend the systematics and classification of these lineages within a UCE phylogenomic framework and through a detailed morphological reappraisal. For estimations of their evolutionary age, we perform and compare outcomes from two divergence estimation approaches, an a posteriori likelihood, and an a priori Bayesian. Phylogenies reject the monophyly of both Pisauridae and Dolomedes: 1) Focal Clade I groups true Pisauridae genera including Pisaura; 2) Focal Clade II contains Blandinia and is sister to Trechaleidae and Lycosidae; 3) Focal Clade III groups Dolomedes, Megadolomedes, and Ornodolomedes, and is sister to Blandinia, Trechaleidae, and Lycosidae. We therefore propose to delimit Pisauridae by removing Dolomedidae rank resurrected (including Dolomedes, Bradystichus, Megadolomedes, Caledomedes, Mangromedes, Ornodolomedes, and Tasmomedes) and Blandinia incertae sedis. Likelihood and Bayesian time calibration approaches yield comparable divergence estimations: Pisauridae origin is estimated at 29–40 Ma; Blandinia 21–34 Ma; Dolomedidae 10–17 Ma; Dolomedes 9–16 Ma. Reconstructions suggest that the evolution of terrestrial and web-building lifestyles from semi-aquatic ancestors in Pisauridae coincided with cooling and drying climates during the mid-Miocene, but this was not the case in the few recent cases of terrestrialization in Dolomedes species. This historic reconstruction illustrates how climatic changes, or rapid radiation, can drive lifestyle diversification.

Mountains of Slovenia
Mauro Hrvatin, Matija Zorn, 2026, samostojni znanstveni sestavek ali poglavje v monografski publikaciji

Povzetek: Slovenia’s mountainous areas comprise Alpine mountains, Alpine hills, and Dinaric plateaus, which together cover over half of the country. Its mountainous landscapes lie at the intersection of the geotectonic units of the Dinarides, Southern Alps, and Eastern Alps. Limestone and dolomite predominate, although there are also extensive areas in the Alpine hills composed of poorly permeable clastic, igneous, and metamorphic rock. In terms of geomorphological development, mountainous areas can be divided into glacial, fluvio-denudational, and karst landscape types. Glacial landscapes are limited to areas that were exposed to glacial erosion and accumulation during the cold Pleistocene periods, and fluvio-denudational landscapes are typical of areas made of poorly permeable rocks and characterized by surface runoff. Karst landscapes developed on carbonate rocks. They are characterized by intense chemical dissolution of the bedrock and subterranean karst hydrology. The high mountains feature a combination of glacial and karst landscapes, or glaciokarst. Due to the Alpine–Dinaric barrier, Slovenia’s climate is wetter than average. Over the past decades, the average air temperature has been rising rapidly, which causes frequent droughts in the summer and reduces the duration and depth of snow cover in the winter. Climate change has already resulted in significantly lower discharges of mountain rivers and altered discharge regimes. Water conditions largely depend on the rock composition. Nearly two-thirds of mountainous areas is karst and almost devoid of surface water flows, while elsewhere the river system is highly branched. The predominant soils on carbonate rocks are Rendzina and Chromic Cambisol, whereas Dystric Cambisol predominates on non-carbonate rocks. Forest is the natural vegetation and the predominant land-use type in all mountainous areas. The dominant tree is beech, which creates numerous forest communities. Conifers dominate at higher elevations, especially spruce and larch, which grow up to the tree line between 1,550 and 1,900 m. Late-medieval colonization of higher elevations was a key stage in the permanent colonization of mountainous areas, extending even above 1,000 m. In the Alpine mountains, it was the valleys that were usually settled, and in the Alpine hills people also settled the ridges and slopes. The upper limit of settlement in Slovenia’s mountainous areas varies; the highest settlements can be found in the Eastern Karawanks, even at elevations above 1,300 m. The traditional economic activity is forestry.

Phenological observations and potential future shifts in the onset of the selected phenophases of representative spring plant species in Slovenia (Corylus avellana, Taraxacum officinale, and Syringa vulgaris)
Gal Oblišar, Marko Puškarić, Urša Vilhar, 2025, zaključena znanstvena zbirka raziskovalnih podatkov

Povzetek: To assess the changes in the spring phenology in the future with particular emphasison the elevation dependence of phenophase onset, a climate-driven phenological model was developed based on the spring indices methodology. Our study investigates both current and projected changes in the timing of flowering onset for common hazel (Corylus avellana), dandelion (Taraxacum officinale), and common lilac (Syringa vulgaris). We compiled comprehensive climate data and phenological records from 46 phenological stations of the National Phenological Network of the Slovenian Environment Agency for the period 1971–2020.We used climate projection data for the 21st century under two climate scenarios to evaluate potential future shifts in the onset of the selected phenophases. Specifically, we examined whether the agreement between model predictions and observed records varies with elevation during the reference period (1981–2010) and whether this relationship changes across three future climate periods till 2100.

Model results indicate that spring phenophases are expected to occur earlier in Slovenia by the end of the 21st century, consistent with the projected increase in air temperatures. Moreover, the advancement in spring phenology will be more pronounced at higher elevations.

Isotopic composition of precipitation and its role in forest hydrology under climate change: insights from Slovenian lowland forests
Katja Koren Pepelnik, Mitja Janža, Matjaž Čater, Barbara Čenčur Curk, Polona Vreča, 2026, izvirni znanstveni članek

Povzetek: Monitoring of stable isotopes in throughfall (δ18O, δ2H) and meteorological parameters is a valuable tool for researching forest hydrology, particularly during extreme events like droughts and floods. This study presents the first systematic analysis of air temperature and precipitation changes over the past 65 years in two Slovenian lowland forests: Murska šuma and Krakovski gozd, in combination with isotopic composition research of throughfall. The observed rising air temperatures and altered precipitation patterns are reflected in the isotopic composition of throughfall. Over the last 65 years, air temperature has increased by approximately 2.5 °C. Although total annual precipitation amounts have remained relatively stable, in the last 35 years there is a notable decrease in precipitation in growing season and an increase during the dormant season, influenced by air masses of Mediterranean origin. Extreme drought in 2022 and flood in 2023 are confirmed by the Standardized Precipitation Index and isotopic variations in throughfall due to fractionation processes. Annual variability appears as seasonal changes, with sine-curve amplitudes of 3.71‰ in Krakovski gozd and 3.61‰ in Murska šuma. Together with the Local Meteoric Water Lines, these patterns support estimates of groundwater mean residence time and the origin of water used by trees.

Frost ollows as interesting areas of geo-and biodiversity in the Alps
Domen Svetlin, Matej Ogrin, Janez Kermavnar, 2025, samostojni znanstveni sestavek ali poglavje v monografski publikaciji

Povzetek: Frost hollows are areas where cold air pools frequently form due to relief, resulting in specific microclimatic conditions. The different microclimate also manifests itself in specific ecological conditions where only adapted plant communities develop. These unique areas are of high conservation impor-tance as they can provide suitable habitats for cold-adapted plant species that are not found in the surrounding landscape. Such microrefugia are known to maintain relict populations of some endemic species. It can be concluded that frost hollows are special areas in terms of both geodiversity and biodiversity. The chapter discusses the climatological and vege-tation characteristics of frost hollows from the Slovenian alpine areas.

Florian Barbi, Tijana Martinović, Inaki Odriozola, Antonin Machac, Andrea Moravcová, Camelia Algora, Dalibor Ballian, Sebastian Barthold, Vendula Brabcová, Sandra Awokunle Hollá, Zander Rainier Human, Hojka Kraigher, Jelena Lazarević, Clémentine Lepinay, Lenka Mészárosová, Daniel Morais, 2026, izvirni znanstveni članek

Povzetek: Gradients in species diversity across elevations and latitudes have fascinated biologists for decades. While these gradients have been well documented for macroorganisms, there is limited consensus about their universality, shape and drivers for microorganisms, such as fungi, despite the importance of fungal diversity for ecosystem functions and services. We conducted a comprehensive survey of fungal species richness in forests across 17 elevational transects along a latitudinal gradient covering the continental scale of Europe. Diversity patterns along elevational and latitudinal gradients differed among fungal ecological guilds. Diversity of saprotrophs declined with elevation while ectomycorrhizal (ECM) fungal diversity peaked in mid-elevations. Moreover, the diversity of root endophytic fungi increased with latitude but did not change with elevation. Bayesian species distribution modeling suggests that fungal diversity is structured by deterministic rather than stochastic drivers. Importantly, ECM fungal diversity pattern persists even after accounting for the effects of environmental conditions. These results suggest that environmental conditions differentially shape the diversity of fungal guilds along elevational and latitudinal gradients, but this goes beyond soil and climatic factors in the case of ECM fungi. This study paves the way toward a better understanding of fungal diversity gradients across elevations and latitudes, with possible implications for macroecological theory, conservation and management.

Temperature and photoperiod interactions influence the cessation of wood growth in three temperate and boreal conifers
Jianhong Lin, Cyrille Rathgeber, Patrick Fonti, Sergio Rossi, Henri E. Cuny, Edurne Martinez Del Castillo, Katarina Čufar, Jesús J. Camarero, Alessio Giovannelli, Harri Mäkinen, Peter Prislan, Walter Oberhuber, Hanuš Vavrčík, Jianguo Huang, Andreas Gruber, Vladimir Gryc, Václav Treml, Martin De Luis, Jožica Gričar, Nicolas Delpierre, 2026, izvirni znanstveni članek

Povzetek: Cambium phenology is a crucial process in wood production and carbon sequestration of forest ecosystems. Although cambium phenology has been widely studied, research specifically focusing on the cessation of wood formation remains limited. To better understand the influence of environmental and intrinsic factors on the cessation of wood formation, we built and compared three ecophysiological models (temperature sum model, photoperiod-influenced temperature sum model and soil moisture- and photoperiod-influenced temperature sum model) in their ability to predict the date of cessation of xylem cell enlargement (cE) in three major Northern Hemisphere conifer species (Black spruce, Norway spruce and Scots pine). We developed these models based on xylogenesis data collected for 130 site‐years across Europe and Canada. Our results demonstrate that the photoperiod-influenced temperature sum model is well-supported by data across all conifer species, with a RMSE of 9.2 days, suggesting that both temperature and photoperiod are critical drivers of wood growth cessation. However, incorporating soil moisture effects does not improve model performance. Our model effectively captures the inter-site variability in cE across a wide environmental gradient, with a fair model efficiency (ME = 0.51 ± 0.22), but performed less well for annual anomalies (ME = 0.10 ± 0.09). Additionally, we found that the total ring cell number also affected prediction accuracy. Using this model, we reconstructed historical trends in cE over the past six decades and found a trend to delayed cessation dates. This delay varied geographically, with slower shifts at higher latitudes and elevations, likely due to constrained cambial responses and conservative growth strategies in colder regions. Our model framework offers a simple yet accurate approach for predicting wood growth cessation at large spatial scales, providing a basis for integrating cambium phenology into land surface models and forest productivity assessments.

Time-resolved life cycle assessment for sustainable industry : integrating hourly analysis into smart infrastructure and energy management
Jelena Topić Božič, Andreja Dobrovoljc, Simon Muhič, 2025, objavljeni znanstveni prispevek na konferenci

Povzetek: The role of data centers has intensified with the expansion of the digital economy and the advancement of information and communication technologies. Their environmental footprint is determined by the electricity mix, whose temporal and spatial variability is insufficiently addressed in the conventional life cycle assessment (LCA). In this study, a time-resolved environmental impact assessment was applied to electricity generation in Slovenia and Serbia in 2023. The focus was on three categories: climate change, resource use (minerals and metals), and water use. Hourly generation data from the ENTSO-E Transparency platform were linked with the Ecoinvent 3.11 datasets to generate hourly impact profiles and representative daily profiles for summer and winter. The study's results reveal clear differences primarily due to the distinct electricity mix structures of the two countries. Slovenia relies on nuclear, hydro, and photovoltaic power, while Serbia is predominantly coal-based. Photovoltaic generation in Slovenia reduces greenhouse gas emissions during daylight but increases the impacts related to the use of minerals and metals. Serbia exhibits higher climate change burdens yet lower variability in other categories. Seasonal and diurnal fluctuations influence emission intensities, underscoring the limits of static, annualized assessments. The findings provide input for policy and smart infrastructure planning. Strategies for electric vehicle charging, data centers, and demand-side measures should integrate temporal profiles of environmental impacts. Tools such as environmentally differentiated tariffs or time-varying carbon pricing can help align energy use with periods of lower impact. More broadly, the results highlight trade-offs between greenhouse gas mitigation and other pressures, underscoring the need for holistic energy transition pathways.
