2. Isotopic composition of precipitation and its role in forest hydrology under climate change: insights from Slovenian lowland forestsKatja 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.

4. Rastni odzivi bele jelke (Abies alba) in navadne bukve (Fagus sylvatica) na klimatske dejavnike vzdolž Karpatov : doktorska disertacijaPia Caroline Lipužič, 2025, doktorska disertacija Povzetek: Študija je sestavljena iz treh vsebinsko dopolnjujočih sklopov in daje vpogled v najnovejše odzive bele jelke in navadne bukve na okoljske dejavnike ter vključuje napovedi odziva na podnebne spremembe in prispeva pri oblikovanju gozdnogojitvenih usmeritev za gospodarjenje v prihodnje. Vzdolž gorskega masiva Karpatov od smo izbrali osem lokacij v odraslih, optimalno razvitih gospodarskih jelovo-bukovih sestojih in pragozdnih rezervatih nad 800 m nad morjem. Izmerili smo asimilacijski odziv mladja v treh zaporednih rastnih obdobjih in odvzeli izvrtke 15 dominantnih jelk in bukev na izbranih lokacijah za dendrokronološko in lesno-anatomsko analizo. Največjo asimilacijsko učinkovitost jelke smo izmerili v svetlobnih razmerah pod zastorom matičnega sestoja, pri bukvi pa na odprtem. Tako bukev kot jelka kažeta večjo debelinsko rast z več padavinami v juliju in manjšo rast z večjimi povprečnimi in največjimi temperaturami v juniju tekočega leta. Pri jelki smo potrdili statistično značilno pozitivno korelacijo med debelinsko rastjo in temperaturo pozimi, bukev pa negativno korelacijo med debelinsko rastjo in temperaturo poleti. Severna rastišča postajajo za rast obeh vrst ugodnejša, zlasti za jelko. Pri jelki smo potrdili statistično negativno korelacijo med relativno prevodno površino in gostoto celic, povprečno površino celic in gostoto celic ter srednjo debelino tangencialnih celičnih sten in relativno prevodno površino. Izmerjene lastnosti trahej pri bukvi so v korelaciji s širino branik. Bukev in jelka se odzivata na podnebne parametre na izbranih lokacijah različno, pri čemer je jelka bolj odporna na sušo kot bukev.

9. Phenological trends of European beech stands along the Carpathian arc : a 20-year MOD13Q1/MYD13Q1 based analysisM. Švik, O. Brovkina, Tatjana Veljanovski, Matjaž Čater, 2025, izvirni znanstveni članek Povzetek: European forests are severely threatened by rapid global climate change. Predicting the effects of climate change on the future performance of tree species can be enhanced by using geographical gradients as space-time proxies. This study focuses on analysing seasonal and inter-annual phenological trends for eight sites of European beech (Fagus sylvatica L.) in the Carpathians along such geographical gradient. Using time series of the Enhanced Vegetation Index (EVI) from 2003 to 2022, derived from 16-day MODIS Terra and Aqua vegetation products, combined with meteorological parameters (temperature and precipitation) interpolated for a grid and Land Surface Temperature (LST) data from Landsat, we compared annual forest development at the study sites and extracted key phenological metrics (start, length, and end of the growing season) using the phenofit software package for R. Our results show varied responses of the studied forest sites to climate change. The end of season extended significantly at Soveja (slope = 0.50, p = 0.023). Spring temperatures had negative correlations with the start of season (r = -0.37) and autumn temperatures positive correlation with the end of season (r = 0.43). Understanding these patterns is crucial for developing adaptive forest management strategies in Carpathians.

10. The effect of forest gaps on the diversity and composition of bacterial communities in mixed-type forest soils across the Carpathian mountainsNejc Suban, Olivera Maksimović, Nataša Šibanc, Tijana Martinović, Eva Dařenová, Matjaž Čater, Tine Grebenc, 2024, izvirni znanstveni članek Povzetek: Mixed forests of European beech (Fagus sylvatica L.) and silver fir (Abies alba Mill.) play a vital ecological role in Central and South-Eastern Europe. This study investigates the diversity and composition of soil bacterial communities in these forests, focusing on rhizosphere and bulk soils under varying canopy structures. Soil samples were collected from eight sites along the Carpathian Mountains, including managed forests and the remnants of old growth. Metabarcoding of bacterial communities revealed that alpha diversity (species richness, Shannon index, and evenness) was significantly affected by sampling location but not by forest canopy structure or soil type (rhizosphere and bulk soil). The lowest bacterial diversity was found in the old-growth forest of the Beskidy region, while the highest was recorded in managed forest in Vrancea. Beta diversity analyses showed minimal variation between rhizosphere and bulk soil bacterial communities, with geographic distance being the strongest predictor of community composition. Actinobacteriota and Proteobacteria were the dominant phyla across all sites, with higher relative abundance of Actinobacteriota in all rhizosphere samples compared to bulk soil. Complex combinations of various environmental conditions at each sampling location, including soil parameters (mainly pH and C:N ratio), the age of forest gaps, the type and intensity of disturbances, and species composition of above-ground vegetation, can strongly affect soil bacterial communities. A closer examination of additional environmental variables would be necessary to better explain the observed differences in the diversity and composition of bacterial communities.
