Abstract Crown radius (CR) and crown width are fundamental indicators used to describe tree sizes widely included as predictors in growth yield models. is the arithmetic average of two perpendicular diameters each other, obtained from measurements four radii: east, south, west, north. Climate change soil variations influence physiological activities trees, thereby impacting development. However, most CR studies do not quantify impact climate factors on CR. In this study, we developed a nonlinear mixed-effects simultaneous model system address above problems. This study 7188 trees 98 plantation plots Korean pine (Pinus koraiensis) northeast China. The results showed that (extreme temperature precipitation) (total nitrogen) variables improved performance system. large-sized was more sensitive compared smaller trees. Incorporating plot-level random effects into both fitting accuracy predictive width. Our provide new insights environmental variability planted forests suggest integrating modeling can improve results. These findings may become relevant for improving forest management strategies under changing conditions.

Understanding tree growth in relation to environmental conditions is essential, particularly the context of climate change, where rising temperatures, frequent droughts, and disturbances threaten forest health productivity. This study uses high-resolution data from four intensively monitored Picea abies stands Austria (2010–2020), with dendrometers recording hourly stem increments on 10 trees per site, allowing for detailed analysis responses changes. For this purpose we tested different generalized additive mixed models (GAMs) using collected site. The best model consisted combinations soil moisture (SM) temperature (ST) data. Furthermore analyzed how relationships established differ three times during growing season. We found that high SM consistently had a positive effect growth, wheras ST varied depending timing. Our findings underscore importance monitoring conditions, species like , which are known their sensitivity changes due shallow rooting systems vulnerability drought.

Climate change-associated disturbances such as storms, wildfires, and pest outbreaks increasingly destabilize forest systems, threatening their ecological, economic, social functions. These disruptions impact the value chain (FVC) by causing fluctuations in timber supply, from a quantity quality perspective. This study employed operational resilience framework (ORF) to assess FVC five European case studies (CZ, HR, DE, FIN, ESP), focusing on supply key system variable. A assessment was conducted using thresholds, considering sustainability both ecological economic perspectives. Principal component analysis (PCA) identified three predictor groups that influenced resilience: wood production (WP), harvesting systems (HS), management silviculture (MS). Findings revealed regions with proactive sufficient processing capacities ESP) maintained relative stability despite natural disturbances, while others (DE FIN) experienced prolonged instability due market-driven logging practices limited adaptive measures. The highlighted frequent breaching of particularly during high-volume salvage following bark beetle outbreaks, windstorms, wildfires. results emphasized importance integrating strategies mitigate these impacts. ORF demonstrated potential for operationalizing provided guidance improving preparedness against future disturbances.

Abstract Riparian zones are known to control the hydrology and biogeochemistry of forest headwater catchments. Some evidence suggests that these riparian‐stream connections shaped by a relatively small volume soil, or dominant source layer (DSL), through which most water solutes routed laterally. However, hydrological biogeochemical significance DSL has not been broadly evaluated. We compiled data from four headwaters, each different European sites (boreal, temperate, subhumid Mediterranean, semiarid Mediterranean) test whether dimensions characteristics vary predictably across ecoregions based on differences in hydroclimate, topography, soil features. Boreal DSLs were shallow thin, whereas small‐scale topographic heterogeneity at temperate site. In Mediterranean sites, deeper thicker, but upper riparian layers seldomly connected streams had large influence overall lateral flux. Contrasting hydroclimates soils led high dissolved organic carbon concentrations solutions both boreal sites. By contrast, nitrate driven saturation, being orders magnitude higher dry than wet soils. Notably, stream chemistry did consistently reflect flow conditions ecoregions. hypothesize ecoregion‐specific sources bypassing zone, as well in‐stream processes could explain discrepancies. Overall, conceptualizing varied roles diverse systems can aid scientific assessments management land‐water connectivity river networks.

This paper aims to analyze and compare the structure of tree herbaceous plant communities in three temperate forest ecosystems located south Olt County, Romania. The research consisted determining composition by frame quadrats sampling method taxonomic determination species. community was analyzed based on structural indices such as arithmetic mean individuals (X), standard deviation (SD), confidence limits (LC), percentage density (DP), frequency (F), constant (C), relative significance index (W) dominance (ID). results indicated that shows differences depending studied area, but this remains complex uneven. In case trees, species Crataegus monogyna, Quercus robur or Acer campestre tend influence more due an uneven distribution a significant number individuals. As regards species, out 34 identified, only two were noted be present all sites, namely Geum urbanum Viola canina, which reflects higher adaptability their case.
