Abstract :
AimsThe Home-Field Advantage (HFA) suggests that litter decomposes faster in its "home" habitat (home-field) due to local decomposer communities being more adapted to decomposing "home" litter. Elevation-induced micro-environmental variations, may break down the relationship between litter and its associated decomposer communities, reducing decomposition efficiency in home-field environments. In study, we aim to explore whether litter decomposition shows HFA across elevational gradients, the driving factors of litter mass loss in home and away, and what controls the litter HFA along the elevational gradient in subtropical forests.MethodsIn this study, we conducted a foliar litter decomposition translocation experiment along different elevational gradients (900 m-1600 m) in Daiyun Mountain in southeast China, using a 400 m elevational gradient (with a temperature variation of approximately 1.8 degrees C) as the span for litter decomposition. We collected data on environmental factors (e.g., air and soil temperature, soil total C, N, P, and water content), foliar litter quality (e.g., total carbon, nitrogen and phosphorus contents), decomposer communities (soil fungal and bacterial biomass) and plant leaf traits (e.g., leaf total C, N, P, specific leaf area, and leaf dry matter content) at different elevations. Then mixed linear models and structural equation models were used to investigate differences in foliar litter decomposition between home and away fields, as well as the driving factors for HFA.ResultsWe found that (1) Litter decomposition showed HFA across elevational gradients, with foliar litter in home-field losing more mass than in away-field along these gradients. (2) Environmental factors were the main driving factors influencing home-field litter decomposition, while litter quality was the main factor affecting away-field litter decomposition and HFA. Fungal communities enhanced home litter decomposition but not away-field litter, supporting decomposer control in home-field decomposition. (3) From the structural equation model, environmental factors and litter quality were significant positive drivers of HFA. In addition, litter quality was the main factor influencing home-field decomposition, as the faster decomposition of home-field foliar litter was a direct positive contributor to HFA, while slower decomposition of away-field litter had a direct negative effect.ConclusionsFoliar litter decomposition along the elevational gradients exhibited HFA in Daiyun Mountain of subtropical regions, environmental factors are the main factors affecting home litter mass loss, while litter quality is the main factor affecting away litter mass loss and HFA. Additionally, environmental factors influenced microbial communities, with fungal communities having a significant positive effect on the home litter mass loss but no significant impact on away, supporting the decomposer control hypothesis. Therefore, global climate change may affect litter decomposition by altering environmental conditions, which is crucial for nutrient cycling in ecosystems, particularly in mountainous regions where elevational differences create diverse micro-environments. Understanding the Home-Field Advantage at different elevations could help predict forest responses to global change, especially in areas sensitive to elevational shifts in climate.

Abstract :
Monitoring mangrove phenology requires frequent, high-resolution remote sensing data, yet satellite imagery often suffers from coarse resolution and cloud interference. Traditional methods, such as denoising and spatiotemporal fusion, faced limitations: denoising algorithms usually enhance temporal resolution without improving spatial quality, while spatiotemporal fusion models struggle with prolonged data gaps and heavy noise. This study proposes an optimized mangrove phenology extraction approach (OMPEA), which integrates Landsat and MODIS data with a denoising algorithm (e.g., Gap Filling and Savitzky-Golay filtering, GF-SG) and a spatiotemporal fusion model (e.g., Enhanced Spatial and Temporal Adaptive Reflectance Fusion Model, ESTARFM). The key of OMPEA is that GF-SG algorithm filled data gaps from cloud cover and satellite transit gaps, providing high-quality input to ESTARFM and improving its accuracy of NDVI imagery reconstruction in mangrove phenology extraction. By conducting experiments on the GEE platform, OMPEA generates 1-day, 30 m NDVI imagery, from which phenological parameters (i.e., the start (SoS), end (EoS), length (LoS), and peak (PoS) of the growing season) are derived using the maximum separation (MS) method. Validation in four mangrove areas along the coastal China shows that OMPEA significantly improves the potential to capture mangrove phenology in the presence of incomplete data. The OMPEA significantly increased usable data, adding 7-33 Landsat images and 318-415 MODIS images per region. The generated NDVI series exhibits strong spatiotemporal consistency with original data (R2: 0.788-0.998, RMSE: 0.007-0.253) and revealed earlier SoS and longer LoS at lower latitudes. Cross-correlation analysis showed a 2-3 month lagged effects of temperature on mangroves' growth, with precipitation having minimal impact. The proposed OMPEA improves the possibility of capturing mangrove phenology under non-continuous and low-resolution data, providing valuable insights for large-scale and long-term mangrove conservation and management.

【目的】凋落物中难降解物质含量是影响其分解速率的重要内在因素,同时也是森林生态系统养分循环的核心。林窗通过调节森林冠层内外的微气候条件,对凋落物难降解物质的分解产生影响,但其具体响应机制尚不明确。本研究旨在探讨格氏栲天然林林窗对凋落物难降解物质分解的影响,为深入理解森林养分循环提供新视角。【方法】2018年5月底,在三明格氏栲天然林保护区设置林窗与非林窗样地,以格氏栲林混合凋落叶与凋落枝为研究对象,分析不同大小林窗对凋落物难降解物质(单宁、总酚)含量的影响,并揭示其主要驱动因子。【结果】(1)林窗大小显著影响了凋落物难降解物质含量(p<0.001)。大林窗凋落叶单宁分解最快,而非林窗最慢;小林窗凋落枝单宁分解最快,中林窗最慢;大林窗凋落叶总酚分解最快,小林窗最慢;中林窗凋落枝总酚分解最快,非林窗最慢。(2)林窗冠层开阔度和土壤温度对难降解物质分解的影响显著(p<0.05),而土壤微生物多样性的作用相对较弱。【结论】林窗通过调控林下微环境,包括开阔度和土壤温度等,显著影响了凋落物单宁和总酚的分解。研究结果有助于深入理解森林土壤生态平衡和物质循环过程。
