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...

Iron-Nickel-Sulfide Characterisation and Catalytic Testing Data

Claire Mitchell, David Santos-Carballal, Andrew M Beale, Wilm Jones, Sankar Meenakshisundaram & Nora H De Leeuw
Catalytic data describing the production of formate from the hydrogenation of CO2 using iron-sulfide, iron-nickel-sulphide and nickel-sulfide catalysts prepared with different heat treatments under a range of reaction conditions. Catalyst characterisation of these materials include XRD analysis, giving an understanding of the violarite phase and crystallinity. XPS analysis gains understanding of the iron, nickel and sulphur species, and how sulphide and oxide species change under thermal oxidation. XAS analysis employed is vital to gain more...

Data from: Genetic origin, admixture and population history of aurochs (Bos primigenius) and primitive European cattle

Maulik R. Upadhyay, Wei Chen, Johannes A. Lenstra, C. R. J. Goderie, David E. MacHugh, Stephen D. E. Park, David A. Magee, Donato Matassino, Ferdinando Ciani, Hendrik-Jan Megens, J. A. M. Van Arendonk, Martien A. M. Groenen, European Cattle Genetic Diversity Consortium & Richard P. M. A. Crooijmans
The domestication of taurine cattle initiated ~10 000 years ago in the Near East from a wild aurochs (Bos primigenius) population followed by their dispersal through migration of agriculturalists to Europe. Although gene flow from wild aurochs still present at the time of this early dispersion is still debated, some of the extant primitive cattle populations are believed to possess the aurochs-like primitive features. In this study, we use genome-wide single nucleotide polymorphisms to assess...

Data from: Modelling dynamics in protein crystal structures by ensemble refinement

B. Tom Burnley, Pavel V. Afonine, Paul D. Adams & Piet Gros
Single-structure models derived from X-ray data do not adequately account for the inherent, functionally important dynamics of protein molecules. We generated ensembles of structures by time-averaged refinement, where local molecular vibrations were sampled by molecular-dynamics (MD) simulation whilst global disorder was partitioned into an underlying overall translation–libration–screw (TLS) model. Modeling of 20 protein datasets at 1.1–3.1 Å resolution reduced cross-validated R_free values by 0.3–4.9%, indicating that ensemble models fit the X-ray data better than single...

Data from: Miocene flooding events of western Amazonia

Carlos Jaramillo, Ingrid Romero, Carlos D'Apolito, German Bayona, Edward Duarte, Stephen Louwye, Jaime Escobar, Javier Luque, Jorge D. Carrillo-Briceño, Vladimir Zapata, Andrés Mora, Stefan Schouten, Michael Zavada, Guy Harrington, John Ortiz & Frank P. Wesselingh
There is a considerable controversy about whether western Amazonia was ever covered by marine waters during the Miocene [23 to 5 Ma (million years ago)]. We investigated the possible occurrence of Miocene marine incursions in the Llanos and Amazonas/Solimões basins, using sedimentological and palynological data from two sediment cores taken in eastern Colombia and northwestern Brazil together with seismic information. We observed two distinct marine intervals in the Llanos Basin, an early Miocene that lasted...

Data from: Patients’ experiences with a behaviour change intervention to enhance physical activity in primary care: a mixed methods study

Heleen Westland, Jill Sluiter, Sophie Te Dorsthorst, Carin D. Schröder, Jaap C. A. Trappenburg, Sigrid C. J. M. Vervoort & Marieke J. Schuurmans
Objective: To explore the experiences of patients at risk for cardiovascular disease in primary care with the Activate intervention in relation to their success in increasing their physical activity. Methods: A convergent mixed-methods design, parallel to a cluster-randomised controlled trial in primary care, using a questionnaire and semi-structured interviews was conducted. Questionnaires from 67 patients were analysed, and semi-structured interviews of 22 patients were thematically analysed. Experiences of patients who had objectively increased their physical...

Data from: Faunal community consequence of interspecific bark trait dissimilarity in early-stage decomposing logs

Juan Zuo, Matty Berg, Roy Klein, Jasper Nusselder, Gert Neurink, Orsi Decker, Mariet M. Hefting, Ute Sass-Klaassen, Richard S. P. Van Logtestijn, Leo Goudzwaard, Jurgen Van Hal, Frank J. Sterck, Lourens Poorter, Johannes H. C. Cornelissen & Matty P. Berg
Dead tree trunks have significant ecosystem functions related to biodiversity and biogeochemical cycles. When lying on the soil surface, they are colonized by an array of invertebrate fauna, but what determines their community composition is still unclear. We apply community assembly theory to colonization of tree logs by invertebrates. During early decomposition, the attached bark is critically important as an environment filter for community assembly through habitat provision. Specifically, we hypothesized that the more dissimilar...

Data from: Bacterial diversity amplifies nutrient-based plant-soil feedbacks

Simone Weidner, Robert Koller, Ellen Latz, George Kowalchuk, Michael Bonkowski, Stefan Scheu & Alexandre Jousset
Plants foster diverse assemblages of bacteria in the rhizosphere serving important functions which may result in enhanced plant growth. Microbial diversity is increasingly recognized to shape the functionality of microbial communities. This leads to the assumption that there is a positive relationship between rhizosphere diversity and plant growth. Here we investigate how bacterial diversity affects the mineralization of organic matter and plant nutrient acquisition. We hypothesized that altered bacterial diversity will affect nitrogen mineralisation, uptake...

Data from: Sex-related online behaviors, perceived peer norms and adolescents’ experience with sexual behavior: testing an integrative model

Suzan M. Doornwaard, Tom F. M. Ter Bogt, Ellen Reitz & Regina J. J. M. Van Den Eijnden
Research on the role of sex-related Internet use in adolescents’ sexual development has often isolated the Internet and online behaviors from other, offline influencing factors in adolescents’ lives, such as processes in the peer domain. The aim of this study was to test an integrative model explaining how receptive (i.e., use of sexually explicit Internet material [SEIM]) and interactive (i.e., use of social networking sites [SNS]) sex-related online behaviors interrelate with perceived peer norms in...

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...

Data from: Food webs obscure the strength of plant diversity effects on primary productivity

Eric W. Seabloom, Linda Kinkel, Elizabeth T. Borer, Yann Hautier, Rebecca A. Montgomery & David Tilman
Plant diversity experiments generally find that increased diversity causes increased productivity; however, primary productivity is typically measured in the presence of a diverse food web, including pathogens, mutualists and herbivores. If food web impacts on productivity vary with plant diversity, as predicted by both theoretical and empirical studies, estimates of the effect of plant diversity on productivity may be biased. We experimentally removed arthropods, foliar fungi and soil fungi from the longest-running plant diversity experiment....

Data from: Parasites and competitors suppress bacterial pathogen synergistically due to evolutionary trade-offs

XiaoFang Wang, Zhong Wei, Mei Li, Xueqi Wang, Anqi Shan, Xinlan Mei, Alexandre Jousset, Qirong Shen, Yangchun Xu & Ville-Petri Friman
Parasites and competitors are important for regulating pathogen densities and subsequent disease dynamics. It is, however, unclear to what extent this is driven by ecological and evolutionary processes. Here we used experimental evolution to study the eco-evolutionary feedbacks between Ralstonia solanacearum bacterial pathogen, Ralstonia-specific phage parasite and Bacillus amyloliquefaciens competitor bacterium in the laboratory and plant rhizosphere. We found that while the phage had a small effect on pathogen densities on its own, it considerably...

Data from: Periphyton density is similar on native and non-native plant species

Bart M. C. Grutters, Elisabeth Maria Gross, Ellen Van Donk & Elisabeth S. Bakker
Non-native plants increasingly dominate the vegetation in aquatic ecosystems and thrive in eutrophic conditions. In eutrophic conditions, submerged plants risk being overgrown by epiphytic algae; however, if non-native plants are less susceptible to periphyton than natives, this would contribute to their dominance. Non-native plants may differ from natives in their susceptibility to periphyton growth due to differences in nutrient release, allelopathy and architecture. Yet, there is mixed evidence for whether plants interact with periphyton growth...

Data from: Low fitness at low latitudes: wintering in the tropics increases migratory delays and mortality rates in an Arctic breeding shorebird

Jeroen Reneerkens, Tom S.L. Versluijs, Theunis Piersma, Jose Alves, Mark Boorman, Colin Corse, Olivier Gilg, Gunnar Hallgrimsson, Johannes Lang, Bob Loos, Yaa Ntiamoa-Baidu, Alfred Nuoh, Peter Potts, Job Ten Horn & Tamar Lok
1. Evolutionary theories of seasonal migration generally assume that the costs of longer migrations are balanced by benefits at the non-breeding destinations. 2. We tested, and rejected, the null hypothesis of equal survival and timing of spring migration for High Arctic breeding sanderling Calidris alba using six and eight winter destinations between 55° N and 25° S, respectively. 3. Annual apparent survival was considerably lower for adult birds wintering in tropical West-Africa (Mauritania: 0.74 and...

Leading trait dimensions in flood-tolerant plants

Yingji Pan, Ellen Cieraad, Jean Armstrong, William Armstrong, Beverley Clarkson, Ole Pedersen, Eric Visser, Laurentius Voesenek & Peter Van Bodegom
Background and Aims While trait-based approaches have provided critical insights into general plant functioning, we lack a comprehensive quantitative view on plant strategies in flooded conditions. Plants adapted to flooded conditions have specific traits (e.g. root porosity, low root/shoot ratio and shoot elongation) to cope with the environmental stressors including anoxic sediments, and the subsequent presence of phytotoxic compounds. In flooded habitats, plants also respond to potential nutrient and light limitations, e.g. through the expression...

The shape of aroma: X-ray CT scans of citrus fruits, their separate tissues, and their individual oil glands

Erik Amezquita, Michelle Quigley, Tim Ophelders, Danelle Seymour, Elizabeth Munch & Daniel Chitwood
From preventing scurvy to being part of religious rituals, citrus are intrinsically connected to human health and perception. From tiny mandarins to head-sized pummelos, citrus capability of hybridization provides a vastly diverse array of fruit sizes and shapes, which in turn corresponds to a diversity of flavors and aromas. These sensory qualities are tightly linked to oil glands in the citrus skin. The oil glands are also key to understanding fruit development, and the essential...

Integrated population model for the Mallard in the Netherlands

, Eelke Jongejans, Chris A. M. Van Turnhout, Loes Van Den Bremer, Henk Van Der Jeugd & Erik Kleyheeg
Europe’s highest densities of breeding Mallards (Anas platyrhynchos) are found in the Netherlands, but the breeding population there has declined by ~30% since the 1990s. The exact cause of this decline has remained unclear. Here, we used an integrated population model to jointly analyze Mallard population survey, nest survey, duckling survival and band-recovery data. We used this approach to holistically estimate all relevant vital rates, including duckling survival rates for years for which no explicit...

Acoustic recordings and corresponding mammal, bird, human activity, vegetation, and climate data from a tropical forest landscape

Johan Diepstraten, Jacques Kuemo Kuenbou & Jacob Willie
Obtaining and analysing sound data can be a tedious and lengthy process. We present sound data consisting of 38,065 1-minute sound recordings obtained in three sites within a rainforest landscape in southeast Cameroon. The sites differ in anthropogenic disturbance. We also present meta data corresponding to 20,485 of these recordings with the identification of all animal vocalisations in each 1-minute sound recording. Additionally, we provide a raw database with data on habitat, human activities, remoteness,...

High spatial resolution mapping identifies habitat characteristics of the invasive vine Antigonon leptopus on St. Eustatius (Lesser Antilles)

Elizabeth Haber, Maria Santos, Pedro Leitão, Marcel Schwieder, Pieter Ketner, Joris Ernst, Max Rietkerk, Martin Wassen & Maarten Eppinga
On the Caribbean island of St. Eustatius, Coralita (Antigonon leptopus) is an aggressive invasive vine posing major biodiversity conservation concerns. The generation of distribution maps can address these conservation concerns by helping to elucidate the drivers of invasion. We test the use of support vector machines to map the distribution of Coralita on St. Eustatius at high spatial resolution and use this map to identify potential landscape and geomorphological factors associated with Coralita presence. This...

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...

Data from: Gradual warming prior to the end-Permian mass extinction

Jana Gliwa, Michael Wiedenbeck, Martin Schobben, Clemens Vinzenz Ullmann, Wolfgang Kiessling, Abbas Ghaderi, Ulrich Struck & Dieter Korn
The biggest known mass extinction in the history of animal life occurred at the Permian-Triassic boundary and has often been linked to global warming. Previous studies suggested that a geologically rapid (less than 40 kyr) temperature increase of more than 10°C occurred simultaneously with the main extinction pulse. This hypothesis is challenged by geochemical and palaeontological data indicating profound environmental perturbations and a temperature rise prior to the main extinction. Using Secondary Ion Mass Spectrometry...

Grazing and global change factors differentially affect biodiversity-ecosystem functioning relationships in grassland ecosystems

Miao He, Yuhan Pan, Guiyao Zhou, Kathryn Barry, Yuling Fu & Xuhui Zhou
Grazing and global change (e.g., warming, nitrogen deposition and altered precipitation) both contribute to biodiversity loss and alter ecosystem structure and functioning. However, how grazing and global change interactively influence plant diversity, ecosystem productivity, and their relationship remains unclear at the global scale. Here, we synthesized 73 field studies to quantify the individual and/or interactive effects of grazing and global change factors on biodiversity-productivity relationship in grasslands. Our results showed that grazing significantly reduced plant...
