21. Correlation of body composition with speed and agility of children aged 9-10Mima Stanković, Dušan Đorđević, Milan Zelenovic, Danijel Bozic, 2020, izvirni znanstveni članek Povzetek: Purpose: Physical growth of children is measured by changes in body size and/or body composition, as well as by changes in motor skills. Motor skills can be affected by many factors, such as genetic predisposition, body composition, socio-economic conditions, and the like. Accordingly, the aim of the research is to determine the correlation between body composition with speed and agility of children aged 9 to 10 years. Methods: The sample included 40 participants (29 boys and 11 girls, 9.47 ± 0.5 years). Body height (BH), body weight (BW), body mass index (BMI) and body fat (BF), and basal metabolism (BMR) were determined to assess body composition. The BOT-2 subtest was used to assess speed and agility, which includes: Shuttle Run (1SAA), Stepping Sideways over a Balance Beam (2SAA), One-Legged Stationary Hop (3SAA), One-Legged Side Hop (4SAA), Two-Legged Side Hop (5SAA), and Total Speed and Agility (TSAA). Results: The results of correlation statistics indicated the existence of negative correlations between: height and 3SAA (r=-.353, p=.026); weight and 3SAA (r=-.422, p=. 007); weight and TSAA (r=-.359, p=.023); BMI and 3SAA (r=-.342, p=. 031); BMI and TSAA (r=-.333, p=.036); BMR and 3SAA (r=-.369, p=. 019); BMR and TSAA (r=-.363, p=.021). Conclusion: Based on the results obtained in this study, it can be concluded that there is a correlation between body composition and speed and agility. In addition to body composition, a correlation was found between body height and performance of one-legged stationary hop, as well as between basal metabolism, the one-legged stationary hop test and the overall results achieved in motor skill tests.

23. Prostorska variabilnost sezonske količine padavin v Sloveniji v obdobju 2010–2019Milan Kobal, 2022, izvirni znanstveni članek Povzetek: Prostorsko variabilnost količine padavin v Sloveniji smo ovrednotili z analizo razdalje razgradnje korelacije CDD (angl. Correlation Decay Distance), ki prikazuje spremembo korelacije v količini padavin med meteorološkimi postajami glede na njihovo medsebojno oddaljenost. Uporabili smo podatke tistih meteoroloških postaj (n = 160), ki so na isti lokaciji neprekinjeno beležile količino padavin vseh 120 mesecev (december 2009–november 2019). Za vsako meteorološko postajo smo po posameznih letnih časih izračunali mejno razdaljo, pri kateri je korelacija med količino padavin višja od 0,707 (r2 = 0,5). Rezultati kažejo, da se prostorska variabilnost količine padavin med letnimi časi razlikuje, in sicer je najvišja poleti (CDD = 50 km), sledi pomlad (CDD = 76 km) in jesen (CDD = 120 km) ter zima (CDD = 141 km), ko je prostorska variabilnost količine padavin najnižja. Prostorsko gledano je variabilnost količine padavin podobna spomladi in jeseni (najmanjša prostorska variabilnost padavin v V in JV Sloveniji), medtem ko je poleti najnižja v J Sloveniji, pozimi pa v SZ Sloveniji. Karta variogramov prikazuje anizotropijo v razdalji razgradnje korelacije za spomladanske padavine. Višje vrednosti semivariance so očitne v smeri SV-JZ, medtem ko so vrednosti semivariance v smeri JV-SZ precej nižje.

25. Kako nastajajoči vodni kataster vpliva na določanje hidrološke funkcije gozda?Milan Kobal, Janez Pirnat, 2022, izvirni znanstveni članek Povzetek: Sedanji sistem funkcij gozdov, ki ga v osnovi prinaša Zakon o gozdovih iz leta 1993, je potreben nadgradnje, saj je funkcij zelo veliko, njihove vsebine pa se pogosto podvajajo. Ob takratnem prvem kartiranju funkcij gozdov se je gozdarstvo opiralo predvsem na svoje lastne prostorske sloje, zdaj pa so na voljo podrobnejše prostorske zbirke tudi drugih uporabnikov prostora. Oboje je nov izziv za prikazovanje in vsebinsko vrednotenje ukrepov za zagotavljanje trajnosti funkcij gozdov ter prilagojenega gospodarjenja z gozdovi. V prispevku smo obravnavali hidrološko funkcijo gozda, deloma zaradi aktualnih razmer v Slovenij in svetu (poplave, suše), deloma pa zato, ker novejši podatki o vodnem katastru bistveno nadgrajujejo bazo podatkov o vodah. Če kot velikost orisa okrog površinskih voda upoštevamo eno drevesno višino, je to 120.688,64 ha gozdov, kjer bi bila po dosedanjih kriterijih lahko poudarjena hidrološka funkcija gozda. Daleč največ takih gozdov je ob vodotokih, sledijo izviri in mokrotne površine.

29. The influence of land use on the spatial distribution and intensity of heat islands in SloveniaAnica Simčič, Petra Pečan, Mojca Nastran, Milan Kobal, 2021, izvirni znanstveni članek Povzetek: Heat islands (HI) are a common anthropogenic phenomenon and are defined as artificial surfaces (urban areas) that have a higher average temperature than their surroundings (rural areas). The aim of this work was to determine the influence of land use on the spatial distribution and intensity (HIi ) of HI in Slovenia. The MODIS Land Surface Temperature (LST) and Corine Land Cover (CLC) databases were used to perform the analysis. Within the identified HI, two HI levels were determined based on temperature difference. The results revealed a statistically significant negative correlation between HIi and both forest co%ver and forest fragmentation (forest edge density and ratio of mean forest patch size to HI size). Artificial surface was positively correlated with HIi . The results contribute to the understanding of the spatial distribution of HI and HIi and provide informati%on for spatial planning and policy-making to reduce the negative impact of HI.

30. Short-term impacts of harvesting intensity on the upper soil layers in high karst Dinaric fir-beech forestsEmira Hukić, Matjaž Čater, Aleksander Marinšek, Mitja Ferlan, Milan Kobal, Daniel Žlindra, Hamid Čustović, Primož Simončič, 2021, izvirni znanstveni članek Povzetek: The present study addresses the short-term effects of different harvest intensities under close-to-nature selective management on the upper soil layers in Slovenian and Bosnian Dinaric karst fir-beech forests. The different harvest intensities coincided with the single-tree and irregular shelterwood management, common in the region. The effect of harvesting intensity on the upper soil layers (Ol, Of, Ol and 0%10 cm mineral soil) was investigated by a repeated measurements experiment in Slovenia on 27 research plots in close-to nature managed forests. The properties of the upper layers (concentration of SOC and TN, C/N ratio, weights, BD and SOC stocks) were analyzed twice, before (2011) and after (2014) treatment of 50% and 100% harvest intensity in relation to the total standing growing stock of trees. As a control, we used no-treatment <20% harvesting intensity plots. To extend this experiment, we added three comparable plots from the Bosnian site: one in an old-growth forest with 0% harvest intensity and two in the managed forest with <20% harvest intensity. The results of the assessment of mean differences indicated a significant influence of harvesting intensity on the decrease in SOC, TN concentrations, weights and SOC stocks in the organic layers and the increase in BD and SOC stocks in the 0%10 cm mineral soil. The highest relative decreases in Ol, Of and Oh SOC stocks occurred in 50% (%10 and %38%) and 100% (%16 and %49%) harvest intensities. Negligible relative differences in both organic and 0%10 cm mineral layers were found for the <20% harvest intensity in the region. The change in forest light conditions resulting from differences in canopy openness as a function of applied harvest intensity explained the significant difference in the properties of the upper soil layers. The impact of the short-term losses in SOC stocks, in terms of overall soil productivity, may depend on the regeneration dynamics and melioration methods.
