62. Lastnosti lesa iz rudnika SitarjevecMiha Humar, Boštjan Lesar, Davor Kržišnik, Andreja Pondelak, Andrijana Sever Škapin, Angela Balzano, José Gonçalves, 2024, izvirni znanstveni članek Povzetek: Rudarska tradicija v Litiji, segajoča v staro železno dobo, je vključevala intenzivno uporabo lesa v rudnikih, še posebej za podporo in zaščito rovov. Rudnik Sitarjevec je bil znova odprt za turizem leta 2017, in v letu 2021 so odprli glavni rov. Les ostaja ključen material v rudnikih, čeprav so ga v preteklosti nadomeščali z drugimi materiali. Uporabljeni les je izpostavljen razkroju zaradi visoke vlažnosti in gliv, kot je bela hišna goba. Ta gliva lahko povzroči razgradnjo lesa in je pogosta v vlažnih okoljih rudnikov. Obstoj gliv je pomemben, saj lahko vplivajo na obiskovalce rudnika. Visoka relativna zračna vlažnost (96,6 %) in stalna temperatura (10,1 °C) v rudniku ustvarjata razmere, ki so ugodne za rast gliv, vendar pa relativno nizka temperatura ni omejujoč dejavnik za razgradnjo lesa. Koncentracija glivnih spor v rudniku je visoka in je razložena z razširjenostjo gliv v samem rudniku. Poleg tega smo opazili, da je v lesu veliko anorganskih onesnaževal ter veliko kristalov.

63. Cene gozdnih zemljišč v Sloveniji v obdobju 2018-2022Matjaž Dovečar, Jaša Saražin, Matevž Triplat, 2024, izvirni znanstveni članek Povzetek: V prispevku analiziramo trg z gozdnimi zemljišči v Sloveniji v zadnjih petih letih. Kot glavni vir podatkov je bila uporabljena Evidenca trga nepremičnin, iz katere je mogoče s predlaganim metodoloških pristopom izluščiti kupoprodaje z zgolj gozdnimi zemljišči. Analiza podatkov kaže naraščanje cen gozdnih zemljišč skozi čas, statistično pomembne razlike med statističnimi regijami ter obstoj visokih cen gozdnih zemljišč. Z namenom zagotovitve zanesljivih rezultatov smo izločili izrazite vrednosti ali osamelce in tako prikazali bolj reprezentativno stanje nepremičninskega trga z gozdnimi zemljišči v Sloveniji. Aritmetična sredina cen gozdnih zemljišč celotne baze podatkov znaša 2,82 EUR/m 2 , medtem ko ta po odstranitvi osamelcev dosega 0,64 EUR/m 2 s pomembno nižjimi standardnimi odkloni. Petletna rast cen median gozdnih zemljišč na ravni države znaša 17,31 % in se med statističnimi regijami pomembno razlikuje. Raziskava prinaša vpogled v dejanske tržne razmere gozdnih zemljišč, kar je koristno tako za širšo javnost kot za strokovnjake, zlasti cenilce nepremičnin.

64. Patterns of deadwood volume and dynamics in slovenian forestsGal Kušar, Mathias Naumann, 2024, izvirni znanstveni članek Povzetek: Deadwood, and its temporal and spatial variation, plays an important role in several forest ecosystem services. This study demonstrates the assessment of deadwood dynamics using data from Slovenian national forest inventory permanent sampling plots, employing a mass-balance approach. Our results reveal that deadwood volume is a highly variable metric across regions, deadwood types and tree species. Despite the influx of large volumes of new deadwood due to recent natural disturbances, only moderate increases in deadwood volume were observed between 2007 and 2018. This was mainly offset by deadwood losses due to salvage logging and decomposition. The extent of deadwood losses varied considerably by species. We discuss the implications of the calculation method on estimating changes in deadwood volume, compare these findings with existing literature on deadwood and highlight promising areas for future research activities to better understand deadwood dynamics.

66. A five-step framework for creating forests for the futureMarko Kovač, Gregor Božič, Andreja Ferreira, Gal Kušar, Boštjan Mali, 2024, izvirni znanstveni članek Povzetek: Changing environmental conditions, disturbances, and escalating demands for forest ecosystem services require foresters to restore present forestlands with new forest generations that will exhibit ecological integrity, diversity, high adaptive capacity, and the ability to provide essential ecosystem services. Establishing such forests requires careful consideration of the forest landscape and site dynamics. In pursuit of these requirements, we developed a novel framework that enables the restoration of forest sites and promotes the desired features of the forest complex at the same time. This framework was designed with the methods of system engineering and was organized in the same way as the forest planning process. It was tested in the habitat type of Illyrian Fagus sylvatica forests belonging to the Natura 2000 network. The environmental, vegetation, and site conditions were investigated via field inspections, available forest management plans, and simple GIS analyses. Additionally, we established a seminatural stand composed of European beech, sessile oak, sycamore maple, silver fir, and some wild fruit tree species. The survival of planted species was assessed using census and simple random sampling, the performance of provenances by the Student’s test, while microhabitat factors were explored by a one-way ANOVA. The survival rate of key species was estimated to be 55.6%, while that of fruit species was estimated to be 94.5%. Our framework demonstrated satisfactory performance and contained sufficient benchmarks to facilitate consistent decision-making. In the discussion, we elucidate the framework’s primary features and attributes of the mixed stand, where we also expose some open issues to be addressed in the future.

67. Proximity to riverbed influences physiological response of adult pedunculate oak treesLazar Kesić, Matjaž Čater, Saša Orlović, Bratislav Matović, Marko Stojanović, Mirjana Bojović, 2023, izvirni znanstveni članek Povzetek: The pedunculate oak (Quercus robur L.) is economically and ecologically one of the most significant tree species in Serbia, however, little is known about the influence of the riverbed distance and its water supply on ecophysiological responses of this species. Given the limited information on the light-response curve of photosynthesis for oaks in southwest Srem, Serbia, the aim of this paper is to enhance understanding of their ecophysiological responses in this context. Maximum assimilation rate (Amax), the quantum yield (Ф), and light compensation point (LCP) were compared in adult trees situated along the transect from the river: (1) close to the river, (2) intermediate, (3) farthest from the river, and (4) forest reserve (second closest), with the first three transects being managed forests and the last one being an unmanaged forest reserve. The measurements were conducted in July during the first evidence of drought. The highest Amax rates were measured in all light intensities on the site closest to the river and the smallest on the site that was most distant to the water source. The most efficient were trees close to the river and the ones in the forest reserve. No significant difference between compensation points was confirmed for the studied groups of trees, although the forest reserve trees showed slightly higher values. The results demonstrated clear response between transects, which followed the distance from the riverbed. Pedunculate oak's reliance on groundwater is in tight relation with ecophysiological processes in trees; groundwater depletion may threaten its survival in areas distant from the river.

68. Unearthing the soil-borne microbiome of land plantsRaúl Ochoa-Hueso, David J. Eldridge, Miguel Berdugo, Pankaj Trivedi, Blessing Sokoya, Concha Cano-Díaz, Sebastian Abades, Fernando D. Alfaro, Adebola R. Bamigboye, Felipe Bastida, Tine Grebenc, Tina Unuk Nahberger, 2024, izvirni znanstveni članek Povzetek: Plant–soil biodiversity interactions are fundamental for the functioning of terrestrial ecosystems. Yet, the existence of a set of globally distributed topsoil microbial and small invertebrate organisms consistently associated with land plants (i.e., their consistent soil-borne microbiome), together with the environmental preferences and functional capabilities of these organisms, remains unknown. We conducted a standardized field survey under 150 species of land plants, including 58 species of bryophytes and 92 of vascular plants, across 124 locations from all continents. We found that, despite the immense biodiversity of soil organisms, the land plants evaluated only shared a small fraction (less than 1%) of all microbial and invertebrate taxa that were present across contrasting climatic and soil conditions and vegetation types. These consistent taxa were dominated by generalist decomposers and phagotrophs and their presence was positively correlated with the abundance of functional genes linked to mineralization. Finally, we showed that crossing environmental thresholds in aridity (aridity index of 0.65, i.e., the transition from mesic to dry ecosystems), soil pH (5.5; i.e., the transition from acidic to strongly acidic soils), and carbon (less than 2%, the lower limit of fertile soils) can result in drastic disruptions in the associations between land plants and soil organisms, with potential implications for the delivery of soil ecosystem processes under ongoing global environmental change.
