Abstract The soil nitrogen (N) and phosphorus (P) availability often constrains carbon (C) pool, elevated N deposition could further intensify P limitation, which may affect C cycling in these N‐rich P‐poor ecosystems. Soil microbial residues not only organic (SOC) pool but also impact SOC stability through aggregation. However, how nutrient aggregate fractions the residue contribution to is still well understood. We took advantage of a 10‐year field fertilization experiment investigate...
Microbial metabolic products play a vital role in maintaining ecosystem multifunctionality, such as soil physical structure and organic carbon (SOC) preservation. Afforestation is an effective strategy to restore degraded land. Glomalin-related proteins (GRSP) amino sugars are regarded stable microbial-derived C, their distribution within aggregates affects stability SOC sequestration. However, the information about how afforestation microbial contribution pools poorly understood. We...
Afforestation is an effective method to restore degraded land. methods vary in their effects on ecosystem multifunctionality, but soil biodiversity have been largely overlooked. Here, we mapped the and functioning of multiple organism groups resulting from diverse afforestation tropical coastal terraces. Sixty years after bare land (BL), plant species richness abundance litter (398 ± 85 g m-2 ) biomass (179 3.7 t ha-1 native tree mixtures (MF) were restored level forests (NF; 287 21 243.0 33...
Abstract Aims Understanding variation and coordination of leaf traits at multiscales along elevational gradients can help predict the likely responses dominant species to climate change. We seek determine extent which in stomatal, anatomical morphological is associated with environmental factors, whether ecological strategies Cyclobalanopsis shift elevations. Methods In a tropical forest landscape Jianfengling, South China, we determined related stomata, anatomy morphology six evergreen oak...
Abstract Plant invasions pose significant threats to biodiversity and ecosystem functioning, but their impact on soil carbon (C) pools in island ecosystems remains underexplored. This study examined the responses of total C (TC), organic (SOC), inorganic (SIC), microbial‐derived (i.e., amino sugars (ASs) glomalin‐related proteins (GRSP)) tropical forests invaded by Cassytha filiformis , Eupatorium odoratum Wedelia biflora . Results revealed that substantially reduced aboveground belowground...
和切根处理的云南哀牢山亚热带常绿阔叶林控制实验平台, 研究了不同处理(对照、去凋、切根、切根并 增温)下表层矿质土壤(0-5和5-10 cm)与碳氮磷获取相关的胞外酶活性, 包括多酚氧化酶(POX)、过氧化物酶(PER)、β-葡萄糖 苷酶(BG)、β-1,4-N-乙酰氨基葡萄糖苷酶(NAG)和酸性磷酸酶(AP)。结合铵态氮(NH 4 + -N)含量、硝态氮(NO 3 --N)含量、溶解有 机碳(DOC)含量、溶解总氮(DN)含量、土壤含水量(SWC)等相关指标, 探讨凋落物碳输入、根系碳输入和温度变化对土壤胞 外酶活性及其生态化学计量特征的影响。研究结果表明: 在对照样方, 除POX外其余酶活性均为0-5 cm层显著高于5-10 cm 层。与对照相比, 长期的凋落物去除显著降低了0-5 cm层土壤AP和BG活性, 对NAG
