Data from: Chemical regulation of body feather microbiota in a wild bird

Staffan Jacob, Louis Sallé, Lucie Zinger, Alexis S. Chaine, Christine Ducamp, Léa Boutault, Andrew F. Russell & Philipp Heeb
The microbiota has a broad range of impacts on host physiology and behaviour, pointing out the need to improve our comprehension of the drivers of host microbiota composition. Of particular interest is whether the microbiota is acquired passively, or whether and to what extent hosts themselves shape the acquisition and maintenance of their microbiota. In birds, the uropygial gland produces oily secretions used to coat feathers that have been suggested to act as an antimicrobial...

Robin Van Velzen, Rens Holmer, Fengjiao Bu, Luuk Rutten, Arjan Van Zeijl, Wei Liu, Luca Santuari, Qingqin Cao, Trupti Sharma, Defeng Shen, Yuda Roswanjaya, Titis A. K. Wardhani, Maryam Seifi Kalhor, Joelle Jansen, D. Johan Van Den Hoogen, Berivan Güngör, Marijke Hartog, Jan Hontelez, Jan Verver, Wei-Cai Yang, Elio Schijlen, Rimi Repin, Menno Schilthuizen, M. Eric Schranz, Renze Heidstra … & Rene Geurts
Nodules harboring nitrogen-fixing rhizobia are a well-known trait of legumes, but nodules also occur in other plant lineages, with rhizobia or the actinomycete Frankia as microsymbiont. It is generally assumed that nodulation evolved independently multiple times. However, molecular-genetic support for this hypothesis is lacking, as the genetic changes underlying nodule evolution remain elusive. We conducted genetic and comparative genomics studies by using Parasponia species (Cannabaceae), the only nonlegumes that can establish nitrogen-fixing nodules with rhizobium....

Data from: Epigenetic mapping of the Arabidopsis metabolome reveals mediators of the epigenotype-phenotype map

Rik Kooke, Lionel Morgado, Frank FM Becker, Henriette Van Eekelen, Rashmi Hazarika, Qunfeng F Zheng, Ric CH De Vos, Frank Johannes & Joost JB Keurentjes
Identifying the sources of natural variation underlying metabolic differences between plants will enable a better understanding of plant metabolism and provide insights into the regulatory networks that govern plant growth and morphology. So far, however, the contribution of epigenetic variation to metabolic diversity has been largely ignored. In the present study, we utilized a panel of Arabidopsis thaliana epigenetic recombinant inbred lines (epiRILs) to assess the impact of epigenetic variation on the metabolic composition. Thirty...

Data from: Explaining European fungal fruiting phenology with climate variability

Carrie Andrew, Einar Heegaard, Klaus Høiland, Beatrice Senn-Irlet, Thomas W. Kuyper, Irmgard Krisai-Greilhuber, Paul M. Kirk, Jacob Heilmann-Clausen, Alan C. Gange, Simon Egli, Claus Bässler, Ulf Büntgen, Lynne Boddy & Håvard Kauserud
Here we assess the impact of geographically dependent (latitude, longitude and altitude) changes in bioclimatic (temperature, precipitation and primary productivity) variability on fungal fruiting phenology across Europe. Two main nutritional guilds of fungi, saprotrophic and ectomycorrhizal, were further separated into spring and autumn fruiters. We used a path‐analysis to investigate how biogeographic patterns in fungal fruiting phenology coincided with seasonal changes in climate and primary production. Across central to northern Europe, mean fruiting varied by...

Data from: Relative importance of competition and plant-soil feedback, their synergy, context dependency and implications for coexistence

Ylva Lekberg, James D. Bever, Rebecca A. Bunn, Ray M. Callaway, Miranda M. Hart, Stephanie N. Kivlin, John Klironomos, Beau G. Larkin, John L. Maron, Kurt O. Reinhart, Michael Remke, Wim H. Van Der Putten & Ragan M. Callaway
Plants interact simultaneously with each other and with soil biota, yet the relative importance of competition versus plant soil feedback (PSF) on plant performance is poorly understood. Using a meta-analysis of 38 published studies and 150 plant species, we show that effects of interspecific competition (either growing plants with a competitor or singly, or comparing inter- vs. intraspecific competition) and PSF (comparing home vs. away soil, live vs. sterile soil, or control vs. fungicide-treated soil)...

Data from: Cascading spatial and trophic impacts of oak decline on the soil food web

Jara Domínguez-Begines, Gerlinde B. De Deyn, Luis V. Garcia, Nico Eisenhauer & Lorena Gomez-Aparicio
1. Tree defoliation and mortality have considerably increased worldwide during the last decades due to global change drivers such as increasing drought or invasive pests and pathogens. However, the effects of this tree decline on soil food webs are poorly understood. 2. In this study we evaluated the impacts of Quercus suber decline on soil food webs of Mediterranean mixed forests invaded by the exotic oomycete pathogen Phytophthora cinnamomi, using soil nematodes as bioindicator taxa....

Data from: Below-ground resource partitioning alone cannot explain the biodiversity–ecosystem function relationship: a field test using multiple tracers

Annette Jesch, Kathryn E. Barry, Janneke M. Ravenek, Dörte Bachmann, Tanja Strecker, Alexandra Weigelt, Nina Buchmann, Hans De Kroon, Arthur Gessler, Liesje Mommer, Christiane Roscher & Michael Scherer-Lorenzen
1. Belowground resource partitioning is among the most prominent hypotheses for driving the positive biodiversity-ecosystem function relationship. However, experimental tests of this hypothesis in biodiversity experiments are scarce, and the available evidence is not consistent. 2. We tested the hypothesis that resource partitioning in space, in time, or in both space and time combined drives the positive effect of diversity on both plant productivity and community resource uptake. At the community level, we predicted that...

Data from: Calling in the heat: the zebra finch ‘incubation call’ depends on heat but not reproductive stage

Callum S. McDiarmid, Marc Naguib & Simon C. Griffith
Environmental conditions during early development can profoundly impact an organism’s phenotype, potentially resulting in future adaptations. Offspring can often obtain environmental information directly, but in some cases rely on parental cues or signals. It was recently suggested that at high ambient temperatures zebra finch (Taeniopygia guttata) parents use acoustic signals (‘incubation calls’ or hereon ‘v-calls’) to adaptively alter offspring development for hot conditions. However, this conclusion requires a thorough understanding of the timing and production...

Data from: Landscape context and farm uptake limit effects of bird conservation in the Swedish Volunteer & Farmer Alliance

Jonas Josefsson, Tomas Pärt, Ake Berg, Anne Marike Lokhorst & Sönke Eggers
1. In Europe, agri-environmental schemes (AES) have been unsuccessful in halting biodiversity declines to any great extent. Two particular shortcomings of AES include the low farm uptake and the modest efficacy of many AES options. Partly in response to these shortcomings, initiatives encouraging farmers to take an active role in biodiversity conservation have gained in popularity. However, almost no evaluations of such initiatives exist. 2. We evaluated uptake of conservation advice on farms in the...

Data from: Using root traits to understand temporal changes in biodiversity effects in grassland mixtures.

Lisette M. Bakker, Liesje Mommer & Jasper Van Ruijven
Biodiversity-ecosystem functioning (BEF) studies typically show that species richness enhances community biomass, but the underlying mechanisms remain debated. Here, we combine metrics from BEF research that distinguish the contribution of dominant species (selection effects, SE) from those due to positive interactions such as resource partitioning (complementarity effects, CE) with a functional trait approach in an attempt to reveal the functional characteristics of species that drive community biomass in species mixtures. In a biodiversity experiment with...

Data from: Prevalence and correlates of anemia among adolescents in Nepal: findings from a nationally representative cross-sectional survey

Anemia is regarded as major public health problem among adolescents in Low and Middle-Income Countries (LMICs) but there is limited primary data in many countries, including Nepal. This study investigated the prevalence and correlates of anemia in a nationally representative sample of adolescents within the 2014 National Adolescent Nutrition Survey in Nepal. A total of 3780 adolescents aged 10 to 19 years were selected from a cross-sectional survey through multi-stage cluster sampling. Structured interviews, anthropometric...

Data from: Food quality and quantity is more important in explaining foraging of an intermediate-sized mammalian herbivore than predation risk or competition

Martijn J.A. Weterings, Sander Moonen, Herbert H.T. Prins, Sipke E. Van Wieren, Frank Van Langevelde, Martijn J. A. Weterings & Herbert H. T. Prins
During times of high activity by predators and competitors, herbivores may be forced to forage in patches of low-quality food. However, the relative importance in determining where and what herbivores forage still remains unclear, especially for small and intermediate-sized herbivores. Our objective was to test the relative importance of predator and competitor activity, and forage quality and quantity on the proportion of time spent in a vegetation type and the proportion of time spent foraging...

Data from: Quantifying in situ phenotypic variability in the hydraulic properties of four tree species across their distribution range in Europe

Sylvain Delzon, N. González-Muñoz, J. M. Torres-Ruiz, G. Capdeville, F. Sterck, P. Copini, G. Petit, G. Von Arx, A. Lintunen, L. Grönlund, T. Hölttä, M. C. Caldeira, R. Lobo-Do-Vale & M. Peltoniemi
Many studies have reported that hydraulic properties vary considerably between tree species, but little is known about their intraspecific variation and, therefore, their capacity to adapt to a warmer and drier climate. Here, we quantify phenotypic divergence and clinal variation for embolism resistance, hydraulic conductivity and branch growth, in four tree species, two angiosperms (Betula pendula, Populus tremula) and two conifers (Picea abies, Pinus sylvestris), across their latitudinal distribution in Europe. Growth and hydraulic efficiency...

Data from: Differential effects of climate warming on reproduction and functional responses on insects in the fourth trophic level

Cong Chen, Rieta Gols, Arjen Biere & Jeffrey A. Harvey
1. Understanding effects of Anthropogenic Global Warming (AGW) on species interactions is essential for predicting community responses to climate change. However, while effects of AGW on resource-consumer interactions at the first- and second trophic level have been well studied, little is known about effects on interactions at higher trophic levels at the terminal end of food chains (e.g. in the third and fourth trophic levels). 2. Here, we examined the effects of temperature variability by...

Data from: Assessing bottom-trawling impacts based on the longevity of benthic invertebrates

Jan Geert Hiddink, Simon Jennings, Marija Sciberras, Stefan Bolam, Giulia Cambie, Robert McConnaughey, Tessa Mazor, Ray Hilborn, Jeremy Collie, C. Roland Pitcher, Ana Parma, Petri Suuronen, Michel Kaiser, Adriaan Rijnsdorp, Jeremy S. Collie, Michel J. Kaiser, Adriaan D. Rijnsdorp & Robert A. McConnaughey
1. Bottom trawling is the most widespread human activity directly affecting seabed habitats. Assessment and effective management of the effects of bottom trawling at the scale of fisheries requires an understanding of differences in sensitivity of biota to trawling. Responses to disturbance are expected to depend on the intrinsic rate of increase of populations (r), which is expected to be linearly related to the reciprocal of longevity. 2. We examine the relationship between the longevity...
