2. The prediction of climate-driven habitat shifts of the rare and threatened moss Buxbaumia viridis in SloveniaDjordje P. Božović, Simona Strgulc Krajšek, Lado Kutnar, Janez Kermavnar, Anže Martin Pintar, Marko S. Sabovljević, 2026, izvirni znanstveni članek Povzetek: Buxbaumia viridis is a peculiar, deadwood-dependent cryptogamous moss characterized by reduced gametophytes and prominent sporophytes that develop directly from the protonema. The species is threatened in many European countries, listed in the EU Habitats Directive (Annex II), and protected under the Bern Convention. We applied ensemble species distribution modelling to project the potential distribution of B. viridis under multiple future climate scenarios and to assess its fate by analyzing the main bioclimatic and habitat factors influencing its survival in Slovenia, on the margin of the south-eastern Alps. The analysis was based on 54 occurrence records combined with bioclimatic, elevation and forest-type data using ensemble species distribution modeling. The models indicate that approximately 12% of Slovenia’s territory is potentially suitable for the species, primarily in mountainous regions, particularly in northern Slovenia. The highest probability of B. viridis occurrence was associated with very low minimum temperatures in the coldest month. Future projections predict a strong reduction in potentially suitable areas, ranging from 67.7 to 100%—depending on the reference period and emission scenario—indicating severe range contraction and a potential loss of suitable habitats and underscoring the urgent need for targeted conservation, monitoring and forest management strategies that preserve deadwood-rich forest stands with spruces and firs, to ensure long-term survival of B. viridis in Slovenia.

3. Drivers of belowground properties in fir-beech karst forests a decade after silvicultural treatmentTanja Mrak, Janez Kermavnar, Lado Kutnar, Petr Baldrian, Nataša Šibanc, Vendula Brabcová, Tijana Martinović, David Lenarčič, Martina Štursová, 2026, izvirni znanstveni članek Povzetek: Silvicultural treatments, such as thinning and clearcutting, significantly alter belowground forest processes, yet post-treatment forest ecology remains poorly understood, particularly within temperate mixed and broadleaved forests. Ten years after silvicultural treatments, we investigated fine root biomass (FRB), soil properties, microbial parameters (microbial biomass, mycelium production, potential decomposition) and vegetation cover (canopy, shrub, herb), in Dinaric fir-beech forests on high karst plateaus of Slovenia. We compared these parameters in 27 plots including control, thinning (50%), and clearcut sites. Tree FRB was significantly reduced in clearcuts (− 80.5%) but not in thinned plots, where high local variability was found. Despite reduced tree FRB, total FRB (trees, shrubs and herbs) remained comparable across treatments, indicating compensatory growth of shrubs and herbs. Clearcutting shifted fine root community composition toward beech dominance and increased cover and productivity of herb layer. Arbuscular fungal biomass and decomposition potential were significantly higher in clearcuts, while mycelium production correlated positively with tree FRB and negatively with nutrient-rich conditions. Our findings show that thinning was related to higher biomass of tree fine roots and associated microorganisms, while clearcutting corresponded to dominance of shrubs and herbs, increased decomposition rates and showed moderate positive association with increased soil nutrient levels. A suite of factors associated with the absence or reduction of tree cover may be driving altered nutrient cycling under herb dominated vegetation. Results also suggest a potential role of bacteria in the decomposition processes, particularly in sites with elevated atmospheric N inputs. These results highlight the importance of selecting appropriate intensity of silvicultural treatment and incorporating belowground processes in forest management of Dinaric fir-beech forests.
