Data from: Nonlinearity of root trait relationships and the root economics spectrum

Deliang Kong, Junjian Wang, Huifang Wu, Oscar J. Valverde-Barrantes, Ruili Wang, Hui Zeng, Paul Kardol, Haiyan Zhang & Yulong Feng
The root economics spectrum (RES), a common hypothesis postulating a tradeoff between resource acquisition and conservation traits, is being challenged by conflicting relationships between root diameter, tissue density (RTD) and root nitrogen concentration (RN). Here, we analyze a global trait dataset of absorptive roots for over 800 plant species. For woody species (but not for non-woody species), we find nonlinear relationships between root diameter and RTD and RN, which stem from the allometric relationship between...

Data from: An alternative approach to reduce algorithm-derived biases in monitoring soil organic carbon changes

Weixin Zhang, Yuanqi Chen, Leilei Shi, Xiaoli Wang, Yongwen Liu, Rong Mao, Xingquan Rao, Yongbiao Lin, Yuanhu Shao, Xiaobo Li, Cancan Zhao, Shengjie Liu, Shilong Piao, Weixing Zhu, Xiaoming Zou & Shenglei Fu
Quantifying soil organic carbon (SOC) changes is a fundamental issue in ecology and sustainable agriculture. However, the algorithm-derived biases in comparing SOC status have not been fully addressed. Although the methods based on equivalent soil mass (ESM) and mineral-matter mass (EMMM) reduced biases of the conventional methods based on equivalent soil volume (ESV), they face challenges in ensuring both data comparability and accuracy of SOC estimation due to unequal basis for comparison and using un-conserved...

Data from: Resource addition drives taxonomic divergence and phylogenetic convergence of plant communities

1. Anthropogenic environmental changes are known to affect the Earth’s ecosystems. However, how these changes influence assembly trajectories of the impacted communities remains a largely open question. 2. In this study, we investigated the effect of elevated nitrogen (N) deposition and increased precipitation on plant taxonomic and phylogenetic β-diversity in a 9-year field experiment in the temperate semi-arid steppe of Inner Mongolia, China. 3. We found that both N and water addition significantly increased taxonomic...

Data from: Root feeding larvae increase their performance by inducing leaf volatiles that attract aboveground conspecific adults

Xiao Sun, Evan Siemann, Zhen Liu, Qiyun Wang, Dingli Wang, Wei Huang, Chujun Zhang & Jianqing Ding
1.Herbivore‐induced changes in plant volatile emissions mediate above‐belowground interactions by determining host plant colonization of different herbivores. By changing shoot‐emitted volatiles, belowground herbivores may use the plant to extend their capacity to interact with aboveground con‐ and heterospecifics. 2.We investigated the attractiveness of Triadica sebifera plants infested by larvae of a specialist beetle or root‐knot nematodes to aboveground herbivores. We then determined the contribution of leaf volatiles to the observed recruitment patterns using olfactometer experiments....

Flexible habitat choice by aphids exposed to multiple cues reflecting present and future benefits

Yin Wandong, Xue Qi, Tian Baoliang, Yang Shujian, Li Zhengying, Chen Zhaozhao, Ryan Michael & Hoffmann Ary
Mothers choose suitable habitats for laying offspring to maximize fitness. Since habitat quality varies in space and time, mothers gather information to choose among available habitats through multiple cues reflecting different aspects of habitat quality at present and in the future. However, it is unclear how females assess and integrate different cues associated with current rewards and future safety to optimize oviposition/larviposition decisions, especially across small spatial scales. Here we tested the individual and interactive...

Data from: Biogeographic variation of distance-dependent effects in an invasive tree species

Qiang Yang, Jianqing Ding & Evan Siemann
1.Plant pathogens and herbivores can maintain forest diversity by reducing survival of tree seedlings close to conspecifics. However, how biogeographic variation in these natural enemies affects such distance‐dependent processes is unknown. Because invasive plants escape ecologically important enemies when introduced to a new range, distance‐dependent mortality may differ between their native and introduced ranges. 2. Here, we test whether the invasive tree Triadica sebifera escaped distance‐dependent mortality when introduced to the US from China, and...

Data from: Litter addition decreases plant diversity by suppressing seeding in a semi-arid grassland, Northern China

Ang Zhang & Shiqiang Wan
Plant community diversity is conducive to maintain the regional ecosystems stability and ecosystem services. Seed germination is one of the main ways to regulate plant diversity, owing to seedling recruitment as a basis for plant community renewal. However, the exact mechanism of how plant litter affects seedling recruitment and species richness is not yet fully understood. Therefore, a litter addition and removal experiment were established in a semiarid grassland to study the effects of plant...

Data from: An ignored anatomical variable: pore shape shows a nonrandom variation pattern in xylem cross section

Xiping Zhao, Pingping Guo & Haixin Peng
Anatomical characteristics of vessels have a profound impact on the hydraulic conductivity of the xylem. However, pore shape, the cross-section shape of a vessel, has been ignored in previous hydraulic architecture studies. In this study, we examined whether pore shape tended to be circular, and whether this variation tendency might be affected by water flow path-length and cambial age. The circularity pores in Betula platyphylla Roth and Quercus mongolica (only earlywood) were analyzed from the...
