Abstract Among the various species of trees, black alder ( Alnus glutinosa (L.)

The effects with on recovery litter (thickness, C, N, C/N) soil physicochemical, biochemical, biological, microbial properties trails three levels compactions were examined over a 27‐year period. Results showed that characteristics such as thickness, carbon (C), nitrogen (N), C/N at highest level low intensity traffic compared to those medium frequent intensities. values total porosity, macroporosity, aggregate stability, silt, clay lowest natural stand. pH, ratio, C storage recorded under trail machine passages. physical chemical significantly higher after period 27 years where was performed trails, levels, well undisturbed area.

Abstract Background Photodegradation of plant litter plays a pivotal role in the global carbon (C) cycle. In temperate forest ecosystems, exposure to solar radiation can be significantly altered by changes autumn phenology and snow cover due climatic change. How this will affect decomposition nutrient dynamic interacting with canopy structure (understorey vs. gaps) is uncertain. present study, we conducted field experiment using leaf early-fall deciduous Betula platyphylla (Asian white birch) late-fall Quercus mongolica (Mongolian oak) explore effect change on dynamics gap understorey mixed forest. Results Exposure full-spectrum not only increased loss mass, C, lignin, but also modified N through both immobilization mineralization during initial opening, irrespective species. These effects were mainly driven blue-green spectral region sunlight. Short-term photodegradation had positive legacy later particularly gap, increasing mass 16% 19% for Asian birch Mongolia oak, respectively. Conclusions Our results suggest that earlier leaf-fall and/or land-use or climate would increase organic matter radiation, accelerate ecosystem processes, C cycling ecosystems. The study provides reference predictive research under background

Abstract Variations in plant traits are indicative of adaptations to forest environments, and studying their relationships with tree growth provides valuable insights into regeneration. The spatial arrangement seeds within the litter or soil critically influences variations root–leaf traits, thereby affecting adaptive strategies emerging seedlings. However, our current understanding impacts individual on seedling different relative position, whether these together affect growth, remains limited. This study focuses dominant species, Castanopsis kawakamii, Sanming C. kawakamii Nature Reserve China. present experiment aimed examine seedling, focus positions layers: beneath above layer, bare layer (without litter). Our findings provided evidence supporting a coordinated relationship between root leaf wherein varied conjunction seeds. Specifically, we observed that seedlings exhibited higher values for specific area average diameter, while displaying lower tissue density. mixed model explained 86.1% variation surpassing by positions. Furthermore, nitrogen acted as mediator, regulating specifically dry matter content Therefore, future studies should consider artificially manipulating species diversity based characteristics promote recovery.
