Data from: Insect pollinators show constancy for different flower traits between the most‐ and less‐preferred plants: a case study of the long‐proboscid tangle‐veined fly

Bo Du, Li‐Fang Gao, Yu‐Jie Wang, Hai‐Yang Zhang, Wen Zhang, Xiao‐Dan Zhang & Zhen‐Qin Zhu
1. The coevolution of insect pollinators and their host plants is a typical example of natural selection; however, it remains unclear as to how insect pollinators avoid overdependence on one peculiar plant. As most insect pollinators exhibit a diet breadth when showing flower constancy, to determine the difference and similarity of most and less-preferred flowers by insect pollinators may be helpful to understand their trade-off between flower constancy and overdependence. 2. We addressed this question...

Data from: Trial marriage model – female mate choice under male interference

Bo Du, Meng-Yao Li, Zhuo-Song Geng, Peng Liao, Xiao-Yang Wang, Tian-Chang Yang, Jing-Yuan Wang, Dan-Dan Wang & Li-Fang Gao
In sexually reproducing animals, the process of mate choice by females is often mixed with the process of male-male competition. Current models of female male choice focus mainly on how females identify the higher quality of males, but neglect the effect of male-male competition on the mate choice of females. Therefore, it remains controversial what is the relative importance of two processes in forming a social bond. We propose a new “trial marriage” model for...

Fast and furious: Early differences in growth rate drive short-term plant dominance and exclusion under eutrophication

Yann Hautier, Zhang Pengfei, Mariet Hefting, Merel Soons, George Kowalchuk, Mark Rees, Andrew Hector, Lindsay Turnbull, Xiaolong Zhou, Zhi Guo, Chengjin Chu, Guozhen Du & Yann Hautier
1. The reduction of plant diversity following eutrophication threatens many ecosystems worldwide. Yet, the mechanisms by which species are lost following nutrient enrichment are still not completely understood, nor are the details of when such mechanisms act during the growing season, which hampers understanding and the development of mitigation strategies. 2. Using a common garden competition experiment, we found that early-season differences in growth rates among five perennial grass species measured in monoculture predicted short-term...

Impact of soil temperature-difference on desert carbon-sink

Fan Yang, Jianping Huang, Qing He, Chenglong Zhou, Honglin Pan, Wen Huo, Xinqian Zheng, Haipeng Yu, Xiaoyue Liu, Lu Meng, Dongliang Han, Mamtimin Ali & Xinghua Yang
The global carbon-cycle is crucial for climate change. Desert, which has long been neglected in the global carbon-cycle, may sequester enormous volumes of CO2 and play the role of a carbon-sink. As the world's second-largest shifting desert, the Taklimakan Desert (TD) contributes substantially to desert carbon-sinks. However, the contributions of the internal processes of the TD to its carbon-sink and the long-term trend of the carbon-sink under climate change are still unclear. This study will...

Competition as a demolition derby: Why tolerating competitors is more important than suppressing them

Daniel Atwater, Ragan M. Callaway & Sa Xiao
Tolerance and suppression are distinct components of competition among plants, and recognizing how they affect competitive outcomes is important for understanding the mechanisms and consequences of competition. We used simulations informed by experimental trials to ask whether tolerance or suppression of competitors was more important for the survival of native plants experiencing competition with an exotic invasive species. When competition was pairwise, tolerance and suppression contributed equally to competitive rank in simulations. However, when multiple...

Dependence of the azure-winged magpie on nest spatial cues in offspring recognition decreases with nestling growth

Bo Du
Various cues have been identified as the basis for animals’ discrimination between kin and non-kin. In altricial birds, these cues show temporal and spatial variations, implying that kin recognition might be condition-dependent. In this study, we hypothesize that parents might be sensitive to the changes in nest spatial position, and that their dependence on the nest spatial cue in offspring recognition decreases with offspring growth. We tested this hypothesis in a Tibetan population of the...

Wind Tunnel Measurements of Aerodynamic Entrainment Rate of Particles

Guang Li, Jie Zhang & Ning Huang
This dataset is related to a wind tunnel experiment of aerodynamic entrainment rate of particles. Wind profiles are measured by pitot tube, for calibrating surface shear stress measured by Irwin sensors. Aerodynamic entrainment rate is measured through the mass difference weighting before and after the erosion event. Each case is repeated three times to find the average value and the error. The experimental setup is showed in figure 1.

Cellulose nanocrystals/graphene oxide composite for the adsorption and removal of levofloxacin hydrochloride antibiotic from aqueous solution

Junhong Tao, Jie Yang, Chengxiao Ma, Junfeng Li, Keqing Du, Zhen Wei, Cuizhong Chen, Zhaoyang Wang, Chun Zhao & Xiaoya Deng
Residual antibiotics in water are often persistent organic pollutants. The purpose of this study was to prepare a cellulose nanocrystals/graphene oxide composite (CNCs-GO) with a three-dimensional structure for the removal of the antibiotic levofloxacin hydrochloride (Levo-HCl) in water by adsorption. The Scanning Electron Microscope (SEM), Fourier Transform Infrared (FT-IR), Energy dispersive spectroscopy (EDS), X-ray Photoelectron Spectroscopy (XPS) and other characterization methods were used to study the physical structure and chemical properties of the CNCs-GO. The...

Impacts of growth form and phylogenetic relatedness on seed germination: a large-scale analysis of a subtropical regional flora

JuHong Wang, GeXi Xu, Chen Wen, YanBo Ma, Wei Qi, ChunHui Zhang & XianLiang Cui
Plant regeneration strategy plays a critical role in species survival and can be used as a proxy for the evolutionary response of species to climate change. However, information on the effects of key plant traits and phylogenetic relatedness on seed germination is limited at large regional scales that vary in climate. To test the hypotheses that phylogenetic niche conservatism plays a critical force in shaping seed ecophysiological traits across species, and also drives their response...

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...

Individual variation in parental tradeoffs between the number and size of offspring at the pre- and post-natal stages

Bo Du, Jian-Chuan Li, Li-Fang Gao, Li-Qing Fan, Shi-Yang Wong, Cong Wei, Hai-Yang Zhang & Wen Zhang
Life-history theory predicts that parents refer to the resources they hold to determine their breeding strategy. In multi-brooded species, it is hypothesized that single-brooded parents produce larger clutches and raise offspring with a brood survival strategy, whilst multi-brooded parents only do this under good breeding conditions. Under poor conditions, they produce smaller clutches and raise offspring with a brood reduction strategy. We tested this hypothesis in the Brown-cheeked Laughing Thrush Trochalopteron henrici, which can breed...

Data from: Plant-type dominates fine-root C:N:P stoichiometry across China: a meta-analysis

Zhiqiang Wang, Shiqi Lv, Hui Song, Mingcheng Wang, Qi Zhao, Heng Huang & Karl Niklas
Aim: Fine roots play an important role in biogeochemical cycling in terrestrial ecosystems. However, our understanding of large scale biogeographic patterns and drivers of fine-root C:N:P stoichiometry is extremely limited. Location: China. Methods: We compiled data for fine-root carbon (C), nitrogen (N) and phosphorus (P) concentrations at 165 sites across China to explore large-scale biogeographic patterns and drivers of fine-root C:N:P stoichiometry. Results: The geometric means of fine-root C, N, and P concentrations were 448.81...

Data from: Harsh environmental regimes increase the functional significance of intraspecific variation in plant communities

Kechang Niu, Shiting Zhang & Martin Lechowicz
The relative importance of intraspecific trait variation (rITV) for functional diversity (FD) in plant communities is increasingly apparent, but the influence of abiotic factors on the balance between intraspecific and interspecific effects in contrasting environments is uncertain. We predicted that rITV would increase with environmental harshness as a result of decreasing interspecific variation (Inter_FD) and concomitant increases in between-population ITV(Intra_FD). We empirically tested this prediction in a comparison of rITV for five traits (mature plant...
