Abstract Clonal plants benefit from the ability to translocate resources among interconnected ramets colonize stress habitats. Despite fact that physiological integration of clones may influence their general performance and competitiveness, we still lack an understanding how alters compete with neighbours. In a greenhouse experiment, investigated clonal perennial herbaceous Cynodon dactylon , which originated two flooding ecotypes, influenced growth, functional traits, biomass allocation relative competitiveness intraspecific interspecific We also used reciprocal transplant experiment assess plasticity adaptation test ‘home‐field’ advantage on The findings showed that, for low‐stress significantly enhanced specific root length, storage, root‐shoot ratio, competitive neighbours, but it had little effect overall neighbours across ecotypes. Interestingly, such encouragement helped expand, suggesting physiologically independent can one another. home‐field advantages were demonstrated by home site more than away site. This study provides novel evidence facilitation between has implications environments where both high levels clonality are expected occur.

During flooding in the Water Level Fluctuation Zone (WLFZ), nutrient levels of nitrogen (N) and phosphorus (P) overlying water fluctuate due to soil release, impacting decomposition plants like Cynodon dactylon . However, limited research on effects these changes plant release dynamics complicates accurate assessments quality impacts. This study used 8 samples with varying initial simulate N P induced by WLFZ nutrients examined Results showed that significantly increased P, especially as particulate (PN) (PP), affecting both water. After 60 days, lost 47.97%-56.01% dry matter, 43.58%-54.48% total (TN), 14.28%-20.50% (TP). Initial PN dissolved (TDN) promoted matter loss, PP TP while TDN inhibited TN loss. By day 60, no positive correlation was found between plant-released or were negatively correlated TP, indicating an inhibitory effect. Further analysis indicates released from supported formation microbial aggregates, enhancing denitrification removal thus improving purification over time.

Mangrove ecosystems are globally significant for their biodiversity and ecosystem services but face persistent threats from invasive species anthropogenic disturbances. This study investigates the interactions between Cyperus rotundus, a widespread weed, fungal communities in mangrove-adjacent wetlands of Isla Santay, Ecuador. Using metagenomic sequencing ITS region, we analyzed diversity samples an anthropogenically pressured area non-impacted site. Results revealed differences microbial assemblages: rhizosphere sample disturbed exhibited lower richness was dominated by Magnaporthaceae (9%) Aureobasidium melanogenum (5%), both associated with stress-tolerant traits. In contrast, site showed higher diversity, Cladosporium dominicanum (62%) Talaromyces (11%) as dominant endophytic taxa. Principal Coordinates Analysis (PCoA) co-occurrence networks highlighted distinct partitioning two tissues, indicating that C. rotundus mediates composition response to environmental gradients. These findings underscore role plant’s success suggest leveraging beneficial fungi could enhance resilience support wetland restoration. By integrating molecular approaches ecological insights, this work contributes deeper understanding dynamics coastal informs targeted management strategies preserve mangrove habitats.
