20.500.12556/DiRROS-15314 Post-harvest forest herb layer demography : general patterns are driven by pre-disturbance conditions 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. forest succession demographic types community assembly pre-disturbance factors floristic convergence fir-beech forests gozdna sukcesija demografski tipi razvrščanje vrst v združbe dejavniki pred motnjo konvergenca floristične sestave jelovo-bukovi gozdovi true false true Angleški jezik Ni določen Neznano 2022-07-22 11:30:24 2022-07-22 11:30:25 2022-08-21 03:36:44 0000-00-00 00:00:00 2021 0 0 Nasl. z nasl. zaslona; Opis vira z dne 5. 7. 2021; 13 str. article 119121 Vol. 491 2021 0000-00-00 Zaloznikova Objavljeno apc 0000-00-00 0000-00-00 0000-00-00 630*18 1872-7042 10.1016/j.foreco.2021.119121 69244675 RAZ_Kermavnar_Janez_i2021.pdf RAZ_Kermavnar_Janez_i2021.pdf 1 0DBA7352EEDA095BA428D8419897AA70 5bb5d47b9add875ad945ca117682c6596e8039a668c5b98132b5463dc49433c5 f8ea0b3a-17b6-11ed-b6b8-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=20173 https://www.sciencedirect.com/science/article/pii/S0378112721002097?via%3Dihub 1 https://dirros.openscience.si/Dokument.php?lang=slv&id=20172 Gozdarski inštitut Slovenije 0 0 0
