Altering the conductivity of CuO through the formation of intrinsic defects - data

Aleksandar Živković & Nora H De Leeuw
To explore the possibility of improving the photovoltaic properties of CuO, its intrinsic defect properties need to be studied. Datasets arising from density functional theory based calculations are provided in the .xlsx format (can be viewed either by MS Office or Libre Office) comprising 3 data sheets which correspond to the structural, defect formation energies, and electronic properties of CuO with native impurities introduced within. Each sheet has a text header with descriptive data and...

Interaction of SO2 with the Platinum (001), (011) and (111) Surfaces: A DFT Study - data

Marietjie J Ungerer, David Santos-Carballal, Abdelaziz Cadi-Essadek, Cornelia G C E Van Sittert & Nora H De Leeuw
>Density functional theory (DFT) calculations were uasd with long-range dispersion corrections to study the interaction of SO2 with Pt (001), (011), and (111) surfaces. Platinum is a noble metal that is widely used for the electro-catalytic production of H2, which surface reactivity towards SO2 is not yet fully understood. The work involved studying the surface energies of the mayor Pt surfaces with 4 layers, adsorption energy for SO2 on these surfaces, the thermodynamic effect of...

Data from: Cooperation with closely bonded individuals reduces cortisol levels in long-tailed macaques

Martina Stocker, Matthias-Claudio Loretto, Elisabeth H.M. Sterck, Thomas Bugnyar & Jorg J.M. Massen
Many animal species cooperate with conspecifics in various social contexts. While ultimate causes of cooperation are being studied extensively, its proximate causes, particularly endocrine mechanisms, have received comparatively little attention. Here, we present a study investigating the link between the hormone cortisol, cooperation and social bonds in long-tailed macaques (Macaca fascicularis). We tested 14 macaques in a dyadic cooperation task (loose-string paradigm), each with two partners of different social bond strength and measured their salivary...

Global patterns of the leaf economics spectrum in wetlands

Yingji Pan, Ellen Cieraad, Jean Armstrong, William Armstrong, Beverley Clarkson, Timothy Colmer, Ole Pedersen, Eric Visser, Laurentius Voesenek & Peter Van Bodegom
The leaf economics spectrum (LES) describes consistent correlations among a variety of leaf traits that reflect a gradient from conservative to acquisitive plant strategies. So far, whether the LES holds in wetland plants at a global scale has been unclear. Using data on 365 wetland species from 151 studies, we find that wetland plants in general show a shift within trait space along the same common slope as observed in non-wetland plants, with lower leaf...

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...

Thermal properties and segregation behaviour of Pt nanowires modified with Au, Ag and Pd atoms: A Classical Molecular Dynamics Study - data

Thobani G Gambu, Umberto Terranova, David Santos-Carballal, Melissa A Petersen, Glenn Jones, Eric Van Steen & Nora H De Leeuw
The thermal properties of bimetallic Pt nanowires have been investigated using classical interatomic potentials. Edge decorated Pt nanowires may improve the inter-facet exchange of reaction intermediates resulting in improved oxygen reduction reaction activities at fuel call cathode electrodes. In this work we report on the melting behaviour of Pt-based nanowires where either an edge atomic row or atomic shell of Pt nanowires are substituted by Au, Ag or Pd. Our overall intention is to find...

Data from: Drivers of plant traits that allow survival in wetlands

Yingji Pan, Ellen Cieraad, Bev Clarkson, Tim Colmer, Ole Pedersen, Eric Visser, Laurentius A.C.J. Voesenek & Peter Van Bodegom
Plants have developed a suite of traits to survive the anaerobic and anoxic soil conditions in wetlands. Previous studies on wetland plant adaptive traits have focused mainly on physiological aspects under experimental conditions, or compared the trait expression of the local species pool. Thus, a comprehensive analysis of potential factors driving wetland plant adaptive traits under natural environmental conditions is still missing. In this study, we analysed three important wetland adaptive traits, i.e. root porosity,...

Greenland Marine-Terminating Glacier Retreat Data

Michael Wood, Eric Rignot, Anders Bjørk, Michiel Van En Broeke, Ian Fenty, Dimitris Menemenlis, Mathieu Morlighem, Jeremie Mouginot, Brice Noël, Bernd Scheuchl, Joshua Willis, Hong Zhang, Lu An, Cilan Cai, Emily Kane, Romain Millan & Isabella Velicogna
The thinning, acceleration, and retreat of Greenland glaciers since the mid-1990s has been attributed to the enhanced intrusion of warm Atlantic Waters (AW) into fjords, but this assertion has not been quantitatively tested on a Greenland-wide basis or included in numerical models. Here, we investigate how AW influenced the retreat of 226 marine-terminating glaciers by combining ocean modeling, remote sensing, and in-situ observations. We identify 74 glaciers standing in deep fjords with warm AW that...

Species responses to changing precipitation depends on trait plasticity rather than trait means and intraspecific variation

Bingwei Zhang, Yann Hautier, Xingru Tan, Cuihai You, Marc Cadotte, Chengjin Chu, Lin Jiang, Xinghua Sui, Tingting Ren, Xingguo Han & Shiping Chen
1. Trait-based approaches are key to develop mechanistic understanding of differences in plant species performance under environmental change. While mean trait values have been widely used to link functional traits to species performance, the contribution of intraspecific trait variation and trait plasticity remains unclear. Moreover, environmentally induced changes in species biomass is caused by changes in the number of individuals and individual growth rate, both of which should be influenced by trait differences and plasticity....

Lymph node metastases develop through a wider evolutionary bottleneck than distant metastases

Johannes Reiter, Wei-Ting Hung, I-Hsiu Lee, Shriya Nagpal, Peter Giunta, Sebastian Degner, Gang Liu, Emma Wassenaar, William Jeck, Martin Taylor, Alexander Farahani, Hetal Marble, Simon Knott, Onno Kranenburg, Jochen Lennerz & Kamila Naxerova
Genetic diversity among metastases is poorly understood but contains important information about disease evolution at secondary sites. Here we investigate inter- and intra-lesion heterogeneity for two types of metastases that associate with different clinical outcomes: lymph node and distant organ metastases in human colorectal cancer. We develop a rigorous mathematical framework for quantifying metastatic phylogenetic diversity. Distant metastases are typically monophyletic and genetically similar to each other. Lymph node metastases, in contrast, display high levels...

Bacterial community richness shifts the balance between volatile organic compound-mediated microbe-pathogen and microbe-plant interactions

Raza Waseem, Jianing Wang, Alexandre Jousset, Ville-Petri Friman, Mei Xinlan, Wang Shimei, Zhong Wei & Qi-Rong Shen
Even though bacteria are important in determining plant growth and health via volatile organic compounds (VOCs), it is unclear how these beneficial effects emerge in multi-species microbiomes. Here we studied this using a model plant-bacteria system, where we manipulated bacterial community richness and composition and determined the subsequent effects on VOC production and VOC-mediated pathogen suppression and plant growth-promotion. We assembled VOC-producing bacterial communities in different richness levels ranging from one to twelve strains using...

Data from: Chemical structure predicts the effect of plant-derived low-molecular weight compounds on soil microbiome structure and pathogen suppression

Yian Gu, Xiaofang Wang, Tianjie Yang, Ville-Petri Friman, Stefan Geisen, Zhong Wei, Yangchun Xu, Alexandre Jousset & Qirong Shen
1. Plant-derived low molecular weight compounds play a crucial role in shaping soil microbiome functionality. While various compounds have been demonstrated to affect soil microbes, most data are case-specific and do not provide generalizable predictions on their effects. Here we show that the chemical structural affiliation of low molecular weight compounds typically secreted by plant roots – sugars, amino acids, organic acids and phenolic acids – can predictably affect microbiome diversity, composition and functioning in...

Judith Sitters, E.R. Jasper Wubs, Elisabeth S. Bakker, Thomas W. Crowther, Peter B. Adler, Sumanta Bagchi, Jonathan D. Bakker, Lori Biederman, Elizabeth T. Borer, Elsa E. Cleland, Nico Eisenhauer, Jennifer Firn, Laureano Gherardi, Nicole Hagenah, Yann Hautier, Sarah E. Hobbie, Johannes M.H. Knops, Andrew S. MacDougall, Rebecca L. McCulley, Joslin L. Moore, Brent Mortensen, Pablo L. Peri, Suzanne M. Prober, Charlotte Riggs, Anita C. Risch … &
Grasslands have been subject to considerable alteration due to human activities globally, including widespread changes in populations and composition of large mammalian herbivores and elevated supply of nutrients. Grassland soils remain important reservoirs of carbon (C) and nitrogen (N). Herbivores may affect both C and N pools and these changes likely interact with increases in soil nutrient availability. Given the scale of grassland soil fluxes, such changes can have striking consequences for atmospheric C concentrations...

Data and code from: Phytoplankton thermal responses adapt in the absence of hard thermodynamic constraints

Dimitrios-Georgios Kontopoulos, Erik Van Sebille, Michael Lange, Gabriel Yvon-Durocher, Timothy G. Barraclough & Samraat Pawar
To better predict how populations and communities respond to climatic temperature variation, it is necessary to understand how the shape of the response of fitness-related rates to temperature evolves (the thermal performance curve). Currently, there is disagreement about the extent to which the evolution of thermal performance curves is constrained. One school of thought has argued for the prevalence of thermodynamic constraints through enzyme kinetics, whereas another argues that adaptation can—at least partly—overcome such constraints....

Electronic structure and interface energetics of CuBi2O4 photoelectrodes - data

Freddy E Oropeza, Nelson Y Dzade, Amalia Pons-Marti, Zhenni Yang, Kelvin H L Zhang, Nora H De Leeuw, Emiel J M Hensen & Jan P Hofmann
In this study, the electronic structure of CuBi2O4 has been studied by a combination of hard X-ray photoemission, resonant photoemission and X-ray absorption spectroscopies, and compared with density functional theory (DFT) calculations. The photoemission study indicates that there is a strong Bi 6s-O 2p hybrid electronic state at 2.3 eV below the Fermi level, whereas the valence band maximum (VBM) has a predominant Cu 3d – O 2p hybrid character. XAS at the O K-edge...

Effects of nutrient limitation on the synthesis of N-rich phytoplankton toxins: a meta-analysis

Karen Brandenburg, Laura Siebers, Joost Keuskamp, Thomas Jephcott & Dedmer Van De Waal
Eutrophication has played a major role in the worldwide increase of harmful algal blooms (HABs). Higher input of key nutrients, such as nitrogen (N) and phosphorus (P), can stimulate the growth of harmful algal species in freshwater, estuarine, and coastal marine ecosystems. Some HAB-forming taxa, particularly several cyanobacteria and dinoflagellate species, are harmful through the production of N-rich toxins that have detrimental effects on the environment and human health. Here, we test how changes in...

Data from: Phage combination therapies for bacterial wilt disease in tomato

Xiaofang Wang, Wei Zhong, Keming Yang, Jiangning Wang, Alexandre Jousset, Yangchun Xu, Qirong Shen & Ville-Petri Friman
Bacteriophage have been proposed as an alternative to pesticides to kill bacterial pathogens of crops. However, phage-biocontrol outcomes are still highly variable and poorly understood in natural rhizosphere microbiomes at timescales considering both ecological and evolutionary processes. However, the efficacy of phage-biocontrol is variable and poorly understood in natural rhizosphere microbiomes at timescales considering both ecological and evolutionary processes. We studied the biocontrol efficacy of different phage combinations on Ralstonia solanacearum infection in tomato. Increasing...

Dominant native and non-native graminoids differ in key leaf traits irrespective of nutrient availability

Arthur Broadbent, Jennifer Firn, James McGree, Elizabeth Borer, Yvonne Buckley, W. Stanley Harpole, Kimberly Komatsu, Andrew MacDougall, Kate Orwin, Nicholas Ostle, Eric Seabloom, Jonathan Bakker, Lori Biedermann, Maria Caldeira, Nico Eisenhauer, Nicole Hagenah, Yann Hautier, Joslin Moore, Carla Nogueira, Pablo Peri, Anita Risch, Christiane Roscher, Martin Schuetz & Carly Stevens
Aim Nutrient enrichment is associated with plant invasions and biodiversity loss. Functional trait advantages may predict the ascendancy of invasive plants following nutrient enrichment but this is rarely tested. Here, we investigate 1) whether dominant native and non-native plants differ in important morphological and physiological leaf traits, 2) how their traits respond to nutrient addition, and 3) whether responses are consistent across functional groups. Location Australia, Europe, North America and South Africa Time period 2007...

Sex-specific effects of cooperative breeding and colonial nesting on prosociality in corvids

Lisa Horn, Thomas Bugnyar, Michael Griesser, Marietta Hengl, Ei-Ichi Izawa, Tim Oortwijn, Christiane Rössler, Clara Scheer, Martina Schiestl, Masaki Suyama, Alex H. Taylor, Lisa-Claire Vanhooland, Auguste M. P. Von Bayern, Yvonne Zürcher & Jorg J. M. Massen
The investigation of prosocial behavior is of particular interest from an evolutionary perspective. Comparisons of prosociality across non-human animal species have, however, so far largely focused on primates, and their interpretation is hampered by the diversity of paradigms and procedures used. Here we present the first systematic comparison of prosocial behavior across multiple species in a taxonomic group outside the primate order, namely the bird family Corvidae. We measured prosociality in 8 corvid species, which...
