Jiankun Bai, Yuchen Meng, Ruikun Gou, Jiacheng Lyu, Zheng Dai, Xiaoping Diao, Hongsheng Zhang, Yiqi Luo, Xiaoshan Zhu & Guanghui Lin
Mangrove forests, one of the highest carbon density ecosystems, are very different from other forests as they occupy saline and tidal habitats. Although previous studies in forests, shrublands, and grasslands have shown a positive effect of biodiversity on plant biomass and carbon storage, it remains unclear whether this relation to biodiversity also exists in mangrove forests. Here, we evaluate the possible effects of mangrove species diversity, structural characteristics, and environmental factors on mangrove biomass production...

Leaf size of woody dicots predicts ecosystem primary productivity

Yaoqi Li, Peter Reich, Bernhard Schmid, Nawal Shrestha, Xiao Feng, Tong Lyv, Brian Maitner, Xiaoting Xu, Yichao Li, Dongting Zou, Zheng-Hong Tan, Xiangyan Su, Zhiyao Tang, Qinghua Guo, Xiaojuan Feng, Brian Enquist & Zhiheng Wang
A key challenge in ecology is to understand the relationships between organismal traits and ecosystem processes. Here, with a novel dataset of leaf length and width for 10,480 woody dicots in China and 2,374 in North America, we show that the variation in community mean leaf size is highly correlated with the variation in climate and ecosystem primary productivity, independent of plant life form. These relationships likely reflect how natural selection modifies leaf size across...

Data from: Application of a trait‐based species screening framework for vegetation restoration in a tropical coral island of China

Nan Liu, Chen Wang, Hui Zhang, Hui Liu, Shuguang Jian & Junhua Yan
1. Selecting suitable species for vegetation restoration presents a notable challenge for land managers and scientists. Recently developed trait‐based approaches may be an effective means of overcoming this challenge. However, we lack a trait‐based species screening model that can be used to select potential species for restoration of degraded ecosystems. 2. Here, we developed a species screening model based on quantitative trait‐based theory and a maximum entropy algorithm. The objective was to select more species...

Intra- and interspecific variability of specific leaf area mitigate the reduction of community stability in response to warming and nitrogen addition

Mengjiao Huang, Shaopeng Wang, Xiang Liu, Ming Nie, Shurong Zhou & Yann Hautier
Global environmental changes are reducing the diversity and affecting the functioning of natural ecosystems as well as their ability to reliably provide ecosystem functions and services to mankind. Many studies have shown that a greater plant diversity can stabilize community productivity against environmental fluctuations. However, most of these studies focused on plant species richness, thus overlooking the potential role of functional traits in stabilizing community productivity against environmental fluctuations. Whether and how functional trait mean...

Data from: Individual size variation reduces spatial variation in abundance of tree community assemblage, not of tree populations

Hua-Feng Wang & Meng Xu
Research on individual trait variation has gained much attention because of its implication for ecosystem functions and community ecology. The effect of individual variation on population and community abundance (number of individuals) variation remains scarcely tested. Using two established ecological scaling laws (Taylor's law and abundance–size relationship), we derived a new scaling relationship between the individual size variation and spatial variation of abundance. Tested against multi-plot tree data from Diaoluo Mountain tropical forest in Hainan,...

Nuclear and plastid phylogenomic analyses provide insights into the reticulate evolution, species delimitation and biogeography of the Sino-Japanese disjunctive Diabelia (Caprifoliaceae)

Xiu-Rong Ke, Diego F. Morales-Briones, Hong-Xin Wang, Qing-Hui Sun, Jacob B. Landis, Jun Wen & Hua-Feng Wang
Understanding biological diversity and the mechanisms of the Sino-Japanese disjunctions are major challenges in eastern Asia biogeography. The Sino-Japanese flora has been broadly studied as an ideal model for plant phylogeography. Diabelia (Caprifoliaceae) is an East Asian genus, with a disjunctive distribution across the Sino-Japanese region. However, relationships within Diabelia remain elusive. In this study, we reconstructed the phylogeny of Diabelia and inferred historical biogeography and evolutionary patterns based on nuclear and plastid sequences from...

The allometry of plant height explains species loss under nitrogen addition

Shurong Zhou
Light asymmetry, with a higher light acquisition per unit biomass for larger plants, has been proposed as a major mechanism of species loss after nitrogen addition. However, solid evidence for this has been scarce. We measured the allometric size-height relationships of 25 plant species along a nitrogen addition gradient manipulated annually for eight years in a speciose alpine meadow and found that the positive relationship between species relative abundance and the height scaling exponent in...

A phylogenomic perspective on gene tree conflict and character evolution in Caprifoliaceae using target enrichment data, with Zabelioideae recognized as a new subfamily

Hong-Xin Wang, Diego F. Morales-Briones, Michael Moore, Jun Wen & Hua-Feng Wang
The use of diverse datasets in phylogenetic studies aiming for understanding evolutionary histories of species can yield conflicting inference. Phylogenetic conflicts observed in animal and plant systems have often been explained by hybridization, incomplete lineage sorting (ILS), or horizontal gene transfer. Here, we employed target enrichment data and species tree and species network approaches to infer the backbone phylogeny of the family Caprifoliaceae, while distinguishing among sources of incongruence. We used 713 nuclear loci and...
