202. Post-harvest forest herb layer demography : general patterns are driven by pre-disturbance conditionsJanez Kermavnar, Klemen Eler, Aleksander Marinšek, Lado Kutnar, 2021, original scientific article Abstract: 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.

204. Odmrla biomasa in krajinska povezljivost kot podpora za določanjJanez Pirnat, 2022, original scientific article Abstract: V razpravi predstavljamo nov predlog ocene pestrostne funkcije gozdnih zaplat v kmetijski krajini. V raziskavi smo podrobno ocenili prisotnost odmrle lesne biomase v gozdni zaplati pri Nadgorici. Povprečna vrednost odmrle lesne biomase, izračunana iz 57 vzorčnih ploskev, je znašala 11,83 m3 /ha. Od šestih ploskev (torej nekako 10 % od vseh ploskev) izkazuje lesno zalogo odmrle lesne biomase več kot 25 m3 /ha, torej količino, ki v literaturi velja kot primer poudarjene pestrostne funkcije. Ugotovitve naše raziskave smo povezali še z ugotovitvami naših predhodnih raziskav in literature. Na podlagi vsega navedenega smo oblikovali predlog, da bi poudarjeno pestrostno funkcijo v kmetijski krajini imele zaplate z dovolj veliko količino odmrle lesne biomase (≥ 20 m3 /ha) z vsaj 200 ha velikim jedrom notranjega okolja in prostorskim razporedom, ki vzdržuje manj kot 2 km medsebojno oddaljenost med gozdnimi zaplatami oziroma okoliško gozdno matico.

207. The muscle contractile properties in female soccer players : inter-limb comparison using tensiomyographyArmin Paravlić, Zoran Milanović, Ensar Abazović, Goran Vučković, Darjan Spudić, Živa Majcen Rošker, Maja Pajek, Janez Vodičar, 2022, original scientific article Abstract: Objective: The present study aimed to: i) determine the contractile properties of the major lower limb muscles in female soccer players using tensiomyography; ii) investigate inter-limb differences; and iii) compare inter-limb differences between different selections and playing positions. Methods: A total of 52 female soccer players (A team; U19 and U17) were recruited. The vastus lateralis (VL), vastus medialis (VM), rectus femoris (RF), biceps femoris (BF), gastrocnemius medialis (GM), lateralis (GL) and tibialis anterior (TA) of both lower limbs were evaluated. Results: When the entire sample was assessed regardless of selection or playing position, there were significant inter-limb differences in all measured muscles except BF. Compared to the non-dominant limb, the dominant limb had higher delay time in VL (p=0.008), while showing lower values in VM (p=0.023), GL (p=0.043) and GM (p=0.006). Contraction time was lower in the RF of the dominant limb (p=0.005) and VM (p=0.047), while showing higher values in VL (p=0.036) and TA (p<0.001) as compared to the non-dominant limb. Conclusion: Given the differences found between the limbs in the whole sample studied, it is necessary to examine both limbs to gather a more in-depth understanding of underlying mechanisms related to neuromuscular functions in female soccer players. Level of evidence: Prognostic study, Level II.
