Soil nutrients and meteorological conditions are pivotal environmental factors influencing plant growth development. This study systematically analyzes how soil influence the phenotypic seed production of wild Elymus nutans in Tibet. These critical ecological determinants, this research seeks to unveil complex diverse adaptation mechanisms species. The encompasses ten counties within Tibet Autonomous Region, with sampling points distributed across seven distinct environments. By evaluating root nutrient levels, collecting data, analyzing characteristics elemental composition at various points, assesses adaptability under conditions. Cluster analysis categorized 25 samples into four groups, each exhibiting significant differences height leaf length. Correlation revealed a negative correlation between point elevation NH₄⁺, total phosphorus, available phosphorus content, while positive was observed pH levels. Meteorological variables—including temperature, humidity, precipitation—significantly influenced phenotypes seeds. ammonium nitrogen, vital for nutans, their deficiency has impact on overall growth. Environments characterized by high altitude, aridity, intense radiation constrain Climatic altering environment, where quality plays role determining interact collectively ecosystem.

Abstract Vegetation restoration is essential to manage rocky desertification and restore ecological functions in the karst region of southwest China. However, contributions soil multitrophic microbial diversity network complexity for multifunctionality ecosystem during vegetation remain poorly explored, despite established significance communities regulating various functions. This study aimed investigate bacterial, fungal protistan their hierarchical co‐occurrence networks, as well relationships with (SMF), two different modes: natural forest (NF) artificial (AF), cropland (CL) controls. The significantly increased carbon nitrogen cycling indexes, capacity water regulation SMF ( p < 0.05). exhibited positive correlations composition communities, β‐diversity (e.g. degree average path length). Notably, alterations abundance sensitive amplicon sequence variants (sASVs) within Module 4 positively affected SMF, while sASVs 2 demonstrated a negative correlation under modes vegetation. Furthermore, bacterial keystone taxa, rather than protistan, were negatively associated SMF. Random (RF) modelling further identified Nitrospira , Halomonas Immundissolibacter Rhodoferax Alicycliphilus Castellaniella at genus level critical maintaining Additionally, sources, minor elements exchangeable Mg, Ca, Cu, Zn, Fe Mn) content determined be pivotal driving factors Synthesis applications . These findings provide valuable insights into influence on interactions areas.
