25. Post-harvest forest herb layer demography : general patterns are driven by pre-disturbance conditionsJanez Kermavnar, Klemen Eler, Aleksander Marinšek, Lado Kutnar, 2021, izvirni znanstveni članek Povzetek: Timber harvesting constitutes extensive anthropogenic disturbance in temperate forests, producing a broad range of ecological impacts that most often enhance the demographic processes of vegetation. This study monitored post-harvest herb layer demography over a 6-year period in mesic Dinaric fir-beech forests (Slovenia), a vascular plant diversity hotspot among European forests. Three experimental harvesting intensities, i.e. full harvest (FH), partial harvest (PH) and a control treatment (NH), were each applied over a circular area of 4000 m2 and replicated three times at each of three study sites. Vegetation sampling was conducted before harvesting (in 2012), and two (2014) and six (2018) years following it, in a 400 m2 circular plot positioned in the centre of each treatment area. We focused on identifying general demographic patterns and evaluating the effects of various pre-disturbance abiotic and biotic predictors on compositional responses to disturbance. Two years after harvest (2012-2014), compositional shifts were larger than those in the next 4-year period (2014-2018), confirming the general theoretical prediction that species turnover rate decreases along a successional gradient. The degree of compositional shifts in gaps (FH) and thinned stands (PH) was affected by local abiotic factors (geomorphology of karst sinkholes) and community attributes, such as pre-harvest species richness. Our results indicate that compositional stability is positively associated with pre-disturbance species richness. Over the whole study period, increases in plot-level species richness (alpha diversity) and overall enrichment of the species pool (gamma diversity) were accompanied by compositional convergence, i.e. a decline in floristic dissimilarity (beta diversity) between and within study sites. However, the observed tendency towards homogenization was rather weak and would have been even more pronounced if the demographic type of persistent resident species had not shown a high degree of resistance, thus leaving a strong imprint on post-harvest vegetation development by preserving the forest characteristics of the herb layer community.

26. Variation in floristic and trait composition along environmental gradients in the herb layer of temperate forests in the transition zone between Central and SE EuropeJanez Kermavnar, Lado Kutnar, Aleksander Marinšek, 2022, izvirni znanstveni članek Povzetek: Species- and trait-environment linkages in forest plant communities continue to be a frequent topic in ecological research. We studied the dependence of floristic and functional trait composition on environmental factors, namely local soil properties, overstory characteristics, climatic parameters and other abiotic and biotic variables. The study area comprised 50 monitoring plots across Slovenia, belonging to the EU ICP Forests monitoring network. Vegetation was surveyed in accordance with harmonized protocols, and environmental variables were either measured or estimated during vegetation sampling. Significant predictors of species composition were identified by canonical correspondence analysis. Correlations between plant traits, i.e. plant growth habit, life form, flowering features and CSR signature, were examined with fourth-corner analysis and linear regressions. Our results show that variation in floristic composition was mainly explained by climatic parameters (mean annual temperature, mean annual precipitation), soil properties (pH) and tree layer-dependent light conditions. Trait composition was most closely related with tree layer characteristics, such as shade-casting ability (SCA, a proxy for light availability in the understory layer), tree species richness and tree species composition. Amongst soil properties, total nitrogen content and soil texture (proportion of clay) were most frequently correlated with different species traits or trait states. The CSR signature of herb communities was associated with tree layer SCA, soil pH and mean annual temperature. The floristic composition of the studied herb-layer vegetation depended on temperature and precipitation, which are likely to be influenced by ongoing climate change (warming and drying). Trait composition exhibited significant links to tree layer characteristics and soil conditions, which are in turn directly modified by forest management interventions.

27. Tveganja, koristi in upravljanje s tujerodnimi drevesnimi vrstami v alpskem prostoru : rezultati spletne anketeAnica Simčič, Ajša Alagić, Janez Kermavnar, Lado Kutnar, Simon Zidar, Aleksander Marinšek, 2022, izvirni znanstveni članek Povzetek: Prispevek predstavlja mnenja in poznavanje tujerodnih drevesnih vrst (TDV) deležnikov, ki pri svojem delu prihajajo v stik s TDV v gozdnih, urbanih in periurbanih območjih v Sloveniji. Mnenja smo pridobili s spletno anketo v letu 2020, ki je bila v okviru projekta ALPTREES del raziskave v vsaki od petih partnerskih držav (Slovenija, Avstrija, Nemčija, Italija in Francija) alpskega prostora. Analizirali smo odgovore slovenskih deležnikov in tako pridobili informacije o poznavanju, dojemanju in odnosu deležnikov do TDV. S spletnim anketiranjem smo dobili odgovore na vprašanja 120 posameznikov. Z analizo odgovorov smo ugotovili, da večina anketirancev prepoznava TDV in invazivne tujerodne drevesne vrste (ITDV) v Sloveniji. Na splošno anketiranci menijo, da TDV prinašajo tveganje v alpski prostor. Anketiranci so kot najbolj razširjene TDV ocenili robinijo (Robinia pseudoacacia), veliki pajesen (Ailanthus altissima), pavlovnijo (Paulownia tomentosa), navadno ameriško duglazijo (Pseudotsuga menziesii), rdeči hrast (Quercus rubra) in zeleni bor (Pinus strobus). Med najbolj invazivne TDV uvrščajo robinijo, veliki pajesen, pavlovnijo, octovec (Rhus typhina) in ameriški javor oz. negundovec (Acer negundo). Slaba polovica anketirancev je izrazila srednje veliko zaskrbljenost glede vpliva ITDV, kar četrtina vprašanih pa je zaradi TDV zelo zaskrbljena.
