Background Stem tissue structures are the basis of stem function and essential for maintaining normal physiological metabolism aquatic plants. Water sediment conditions important factors affecting functional characteristics Brassenia schreberi . Due to pollution other water issues caused by human activities, natural habitat population size B. have dramatically decreased. Understanding responses is key its scientific conservation management. Objectives methods This study selected Beihai Wetland in Tengchong, China, which boasts largest , as research site. To detect response strategies conditions, photosynthetic parameters structural this species at 17 locations, well nutrient these locations were measured. We examined relationships between trait using correlation analysis. The aim was explore effects nutrients quality on schreberi. Results conclusions with higher coverage exhibited stomatal conductance ( G s ) transpiration rate T r ), but lower vascular bundle area ventilation hole P <0.05), while net n maintained content, indicating utilization efficiency CO 2 temperature WT nitrogen content ω(N) dissolved oxygen DO main characters significantly negatively correlated it positively phosphorus <0.05). findings indicate that requires good maintain a high prone limitation, has low requirements content. provide restoration species-specific management degraded wetlands.

Specific leaf area (SLA) and dry matter content (LDMC) are key functional traits often used to reflect plant resource utilization strategies predict responses environmental changes. In general, grassland plants at different elevations exhibit varying survival strategies. However, it remains unclear how adapt changes in elevation their driving factors. To address this issue, we utilized SLA LDMC data of from 223 study sites China, along with climate soil data, investigate variations elevational gradients dominant influencing factors employing linear mixed-effects models, variance partitioning method, piecewise Structural Equation Modeling, etc. The results show that increasing elevation, significantly decreases, increases (

Study the leaf functional traits is highly important for understanding survival strategies and climate adaptability of old trees. In this study, (over 100 years old) mature trees (about 50 Pinus tabulaeformis in Loess Plateau were studied, variation 18 (6 economic, 4 anatomical, 2 photosynthetic 6 physiological traits) was analyzed to understand differences between Combined with transcriptome simple sequence repeats (SSR) techniques, effects soil property factors genetic on potential molecular mechanisms studied. Compared trees, presented greater economic (except phosphorus content), anatomical stomatal density), superoxide dismutase activity) lower traits, their more conservative. The difference mainly driven by (common explanation rate 67.89%), independent effect (10.09%) slightly higher than that (2.88%). addition, constructing weighted gene co-expression networks analysis WGCNA), research identified 24 candidate hub genes regulate most which are related plant growth development stress response, can be used further regulatory mechanism analysis. conclusion, study helpful ecological P. tabuliformis under background change Plateau, provides a theoretical basis regulation protection

ABSTRACT Pseudotsuga sinensis is a distinctive plant species endemic to China, predominantly found in areas affected by varying degrees of rocky desertification. Despite its wide distribution, the physiological mechanisms underlying adaptation harsh environments remain unclear. In this study, we investigated 16 leaf traits, including morphological, anatomical, and chemical characteristics leaves P. across forests with mild, moderate, severe, extremely severe desertification elucidate adaptive strategies response arid conditions nutrient‐poor soils. Our findings revealed that from mild moderate exhibited higher specific area (SLA) magnesium concentrations but lower dry matter content (LDMC), abaxial epidermis thickness, adaxial thickness than those Principal component analysis indicated employ resource acquisition characterized greater SLA contrast, adopted resource‐conserving strategies, as evidenced LDMC, epidermal calcium The N:P ratio all levels was consistently below 14, suggesting nitrogen limitation regions Thus, these results provide valuable reference for guiding vegetation restoration under degraded habitats.
