Modifying effect of ant colonization on soil heterogeneity along a chronosequence of tropical forest restoration on slash-burn lands 作者:Lu, M (Lu, Mei)[ 1 ] ; Wang, SJ (Wang, Shaojun)[ 1,2 ] ; Zhang, Z (Zhang, Zhe)[ 1 ] ; Chen, MK (Chen, Minkun)[ 1 ] ; Li, SH (Li, Shaohui)[ 1 ] ; Cao, R (Cao, Run)[ 1 ] ; Cao, QB (Cao, Qianbin)[ 1 ] ; Zuo, QQ (Zuo, Qianqian)[ 1 ] ; Wang, P (Wang, Ping)[ 1 ] SOIL & TILLAGE RESEARCH 卷: 194 文献号: 104329 DOI: 10.1016/j.still.2019.104329 出版年: NOV 2019 文献类型:Article 查看期刊影响力 摘要 Ants act as ecosystem engineers in regulating soil heterogeneities. Little is known about the degree and direction of these modifications on soils across a restoration chronosequence of tropical forests. Our objectives aimed to explore the effect of belowground-nesting ants on soil characteristics across four forest restoration stages (i.e., 12-, 28-, 42- and 53-yr olds) on slash-burn lands in the tropical Xishuangbanna, southwestern China. We confirmed the hypotheses about a positive effect of ant colonization on soil physical characteristics, and on the enrichment of microbial carbon and mineral nutrients in nest soils across the four restoration stages. Ant nests had the highest enrichment of soil organic matter (103%), readily oxidizable carbon (78%), total nitrogen (114%), available nitrogen (126%), NH4+ (133%) and NO3- (140%) at the 12-yr old stage compared with the surrounding soils. In contrast, the highest enrichment of microbial carbon (110%) in nest soils was showed at the 53-yr old stage. The enrichment of microbial carbon in nest soils increased with restoration age, but that of soil mineral nutrients would not follow the forest restorations. A higher enrichment of mineral nutrients in nest soils at the early restoration stage can improve soil fertility, which might promote the spontaneous forest restorations. A higher abundance and area of ant nests at the older restoration stage may create a higher bare space for plant development. Therefore, our results suggest that ant colonization can regulate forest restorations, possibly through creating and maintaining higher soil nutrient heterogeneity at earlier stage, and greatly stirring microbial growth and opening up space for plant development at older stage on slash-burn tropical lands. 关键词 作者关键词:Ant modification; Nutrient enrichment; Slash-Burn tropical forest lands KeyWords Plus:FORMICA-RUFA GROUP; HARVESTER ANTS; LITTER DECOMPOSITION; ATLANTIC FOREST; NITROGEN POOLS; MOUNDS; ECOSYSTEM; VEGETATION; CARBON; NESTS 作者信息 通讯作者地址: Wang, SJ (通讯作者) 显示更多 Southwest Forestry Univ, Coll Ecol & Soil & Water Conservat, 300 Bailongsi, Kunming 650224, Yunnan, Peoples R China. 地址: 显示更多 [ 1 ] Southwest Forestry Univ, Coll Ecol & Soil & Water Conservat, 300 Bailongsi, Kunming 650224, Yunnan, Peoples R China 显示更多 [ 2 ] Nanjing Forestry Univ, Coinnovat Ctr Sustainable Forestry Southern China, 159 Longpan Rd, Nanjing 210037, Jiangsu, Peoples R China 电子邮件地址:wanghn2008@126.com 基金资助致谢 基金资助机构显示详情 授权号 National Natural Science Foundation of China 31660191 41461052 China 948 Program of National Forestry Bureau 2015-4-39 Graduate Tutor Team Building Project of Yunnan province 查看基金资助信息 出版商 ELSEVIER, RADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS 类别 / 分类 研究方向:Agriculture Web of Science 类别:Soil Science 文献信息 语言:English 入藏号: WOS:000486360400050 ISSN: 0167-1987 eISSN: 1879-3444 其他信息 IDS 号: IY4KR Web of Science 核心合集中的 "引用的参考文献": 53 Web of Science 核心合集中的 "被引频次": 0 |
