Bikram Pandey, Janak Khatiwada, Lin Zhang, Kaiwen Pan, Mohammed Dakhil, Qinli Xiong, Ram Yadav, Mohan Siwakoti, Akash Tariq, Olusanya Olatunji, Meta Justine, Xiaogang Wu, Xiaoming Sun, Ziyan Liao & Zebene Negesse
Studying the pattern of species richness is crucial in understanding the diversity and distribution of organisms in the earth. Climate and human influences are the major driving factors that directly influence the large-scale distributions of plant species, including gymnosperms. Understanding how gymnosperms respond to climate, topography, and human-induced changes is useful in predicting the impacts of global change. Here, we attempt to evaluate how climatic and human-induced processes could affect the spatial richness patterns of...

Songbo Tang, Jianfeng Liu, Frank S. Gilliam, Peter Hietz, Zhiheng Wang, Xiankai Lu, Feiyan Zeng, Dazhi Wen, Enqing Hou, Yuan Lai, Yunting Fang, Ying Tu, Dan Xi, Zhiqun Huang, Dianxiang Zhang, Rong Wang & Yuanwen Kuang
Foliar stable nitrogen (N) isotopes (δ15N) generally reflect N availability to plants and have been used to infer about changes thereof. However, previous studies of temporal trends in foliar δ15N have ignored the influence of confounding factors, leading to uncertainties on its indication to N availability. In this study, we measured foliar δ15N of 1,811 herbarium specimens from 12 plant species collected in southern China forests from 1920 to 2010. We explored how changes in...

Functionally dissimilar neighbors improve tree water use efficiency through increases in leaf phosphorus concentration

Zhiqun Huang, Songsong Ran, Yanrong Fu, Xiaohua Wan, Xin Song, Yuxin Chen & Zaipeng Yu
Water use efficiency (WUE) is central to the global cycles of water and carbon. However, whether increasing tree diversity in plantation can increase WUE remain poorly understood. Here, we conduct a forest biodiversity experiment with 32 tree species spread in 14 ha in subtropical China to assess the effects of neighboring tree diversity on foliar WUE of Cunninghamia lanceolata, a widespread tree plantation species in China. We measure foliar δ13C as the proxies of changes...

Data from: Large ecosystem service benefits of assisted natural regeneration

Yusheng Yang, Lixin Wang, Zhijie Yang, Chao Xu, Jingsheng Xie, Guangshui Chen, Chengfang Lin, Jianfen Guo, Xiaofei Liu, Decheng Xiong, Weisheng Lin, Shidong Chen, Zongming He, Kaimiao Lin, Miaohua Jiang & Teng-Chiu Lin
China manages the largest monoculture plantations in the world, with 24% being Chinese fir plantations. Maximizing the ecosystem services of Chinese fir plantations has important implications in global carbon cycle and biodiversity protection. Assisted natural regeneration (ANR) is a practice to convert degraded lands into more productive forests with great ecosystems services. However, the quantitative understanding of ANR ecosystem service benefits is very limited. We conducted a comprehensive field manipulation experiment to evaluate the ANR...

Does land use age influence carbon cycling in the Tibetan Plateau?

Meta Francis Justine, Pan Kaiwen, Nambajimana Jean De Dieu, Fidele Karamage, Zebene Tadesse, Bikram Pandey, Yang Wanqin, Wu Fuzhong, Olusanya Abioudun Olatunji, Nirdesh Nepal, Friday Uchege, Akash Tariq, Lin Zhang & Xiaoming Sun
Although substantial information had been generated on the effects of land use change on soil organic carbon (SOC) and total nitrogen (TN) storage, studies are absent on multifactorial effects of land use types, land use age, and elevation on SOC and TN storage. SOC and TN were therefore investigated in 30 field sites comprising natural forests, planted forests, shrub, and grasslands. SOC and TN stocks differed and correlated significantly with land use age; the C...

Data from: Functional and phylogenetic diversity promotes litter decomposition across terrestrial ecosystems

Wenya Xiao, Chen Chen, Xinli Chen, Zhiqun Huang & Han Chen
Aim: Litter decomposition is a vital process of carbon and nutrient cycling in terrestrial ecosystems. Despite rapid declines in plant diversity worldwide, the plant diversity effects on litter decomposition, along with the factors driving their directions and magnitudes, remain uncertain. Location: Globe. Time period: 1985-2018. Major taxa studied: Plants. Methods: By synthesizing 492 paired observations of leaf litter mixtures and monocultures from 110 studies, we conducted a global meta-analysis of the effects of litter mixtures...

Correlations between dominant vegetation type and composition and diversity of soil bacterial communities in a subtropical forest

Juyan Cui
Single and mixed vegetation types have significant effects on soil parameters and the composition and diversity of soil bacterial communities. To understand the influence of different vegetation types on the structure of soil bacterial community across soil depth in a subtropical forest, we assessed the relative abundance of edaphic bacterial community and soil parameters, including pH, cation exchange capacity (CEC), and dissolved organic carbon (DOC) in Daiyun Mountain Nature Reserve in Fujian Province, southeastern China....

Plant functional traits

Jinlong Li, Xiaoping Chen, Karl Niklas, Jun Sun, Zhaoying Wang, Quanlin Zhong, Dandan Hu & Dongliang Cheng
The whole-plant economics spectrum (PES) refers to the trade-offs among the many plant functional traits that are commonly used as indicators of major adaptive strategies, thereby providing insights into plant distributions, ecosystem processes, and evolution. However, there are few studies of what may be called the whole-plant economic spectrum (PES) that integrates bark, wood, and leaf functional traits for different leaf-types and growth habits (evergreen versus deciduous species). To address this gap in our knowledge,...

Application of leaf size and leafing intensity scaling across subtropical trees

Jun Sun, Xiaoping Chen, Mantang Wang, Jinlong Li, Quanlin Zhong & Dongliang Cheng
Understanding the scaling between leaf size and leafing intensity (leaf number per stem size) is crucial for comprehending theories about the leaf costs and benefits in the leaf size–twig size spectrum. However, the scaling scope of leaf size vs. leafing intensity changes along the twig leaf size variation in different leaf habit species remains elusive. Here, we hypothesize that the numerical value of scaling exponent for leaf mass versus leafing intensity in twig is governed...

Microbial diversity regulates ecosystem multifunctionality during natural secondary succession

Xiuzhen Shi, Jianqing Wang, Manuel Lucas-Borja, Zhenyu Wang, Xue Li & Zhiqun Huang
Natural forest succession after disturbances is one of the most important restoration strategies. However, the responses of ecosystem multifunctionality during natural forest succession remains poorly understood in forest ecosystem. Here we evaluated how the ecosystem multifunctionality including nutrient cycling, carbon stocks, water regulation, decomposition, wood production and symbiosis develops using a chronosequence, and identified the key factors contributing to the variations in the ecosystem multifunctionality during natural forest succession. We provide evidence that the ecosystem...

Soil fungi and fine root biomass mediate drought-induced reductions in soil respiration

Guiyao Zhou, Xuhui Zhou, Ruiqiang Liu, Zhenggang Du, Lingyan Zhou, Songsong Li, Huiying Liu, Junjiong Shao, Jiawei Wang, Yuanyuan Nie, Jie Gao, Minhuang Wang, Mingyue Zhang, Xihua Wang & Shahla Hosseini Bai
Climate change has increased the frequency and intensity of droughts, with potential impacts on carbon (C) release from soil (i.e., soil respiration, Rs). Although numerous studies have investigated drought-induced changes in Rs, how roots and the soil microbial community regulate responses of Rs to drought remains unclear. We conducted a 4-year field experiment (2014 - 2017) with three treatments (i.e., 70% rainfall reduction, control and ambient) in a subtropical forest to examine effects of drought...

Data from: The vertical distribution and control of microbial necromass carbon in forest soils

Xiangyin Ni, Shu Liao, Siyi Tan, Yan Peng, Dingyi Wang, Kai Yue, Fuzhong Wu & Yusheng Yang
Aim: Forest soils contain large amounts of terrestrial organic carbon (C), but the formation pathway of soil organic C (SOC) remains unclear. Recent evidence suggests that microbial necromass is a significant source of SOC, yet a global quantitative assessment across the whole-soil profile is lacking. We aimed to assess the vertical distribution and control of microbial-derived SOC in forest soils. Location: Global forests. Time period: 1996-2019. Major taxa studied: Soil microbial necromass carbon. Methods: We...

Data from: Overestimated gains in water-use efficiency by global forests

Xiao Ying Gong, Wei Ting Ma, Yong Zhi Yu, Keyan Fang, Yusheng Yang, Guillaume Tcherkez & Mark A Adams
Increases in terrestrial water use efficiency (WUE) have been reported in many studies, pointing to potential changes in physiological forcing of global carbon and hydrological cycles. However, gains in WUE are of uncertain magnitude over longer (i.e. >10 years) periods of time largely owing to difficulties in accounting for structural and physiological acclimation. 13C signatures (i.e., δ13C) of plant organic matter have long been used to estimate WUE at temporal scales ranging from days to...
