Data from: Food and nutrient gaps in rural Northern Ghana: does production of smallholder farming households support adoption of food-based dietary guidelines?

Ilse De Jager, Ken E. Giller & Inge D. Brouwer
Food-based dietary guidelines (FBDGs) provide guidance to policy makers, the private sector and consumers to redesign food systems and to improve diets of vulnerable populations. As appropriate FBDGs are based on the actual dietary patterns and their costs, it is assumed that the recommended foods are available, affordable and acceptable for the population under study. Using quantitative dietary intake data of young children in rural Northern Ghana, we developed local FBDGs and studied whether these...

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...

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...

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: 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...

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: Predicting genotypes environmental range from genome-environment associations

Stéphanie Manel, Marco Andrello, Karine Henry, Daphné Verdelet, Aude Darracq, Pierre-Edouard Guerin, Bruno Desprez & Pierre Devaux
Genome-environment association methods aim to detect genetic markers associated with environmental variables. The detected associations are usually analysed separately to identify the genomic regions involved in local adaptation. However, a recent study suggests that single-locus associations can be combined and used in a predictive way to estimate environmental variables for new individuals on the basis of their genotypes. Here, we introduce an original approach to predict the environmental range (values and upper and lower limits)...

Data from: Reanalyzing the Palaeoptera problem - the origin of insect flight remains obscure

Sabrina Simon, Alexander Blanke & Karen Meusemann
The phylogenetic relationships of the winged insect lineages – mayflies (Ephemeroptera), damselflies and dragonflies (Odonata), and all other winged insects (Neoptera) – are still controversial with three hypotheses supported by different datasets: Palaeoptera, Metapterygota and Chiastomyaria. Here, we reanalyze available phylogenomic data with a focus on detecting confounding and alternative signal. In this context, we provide a framework to quantitatively evaluate and assess incongruent molecular phylogenetic signal inherent in phylogenomic datasets. Despite overall support for...

Data from: Opposing patterns of intraspecific and interspecific differentiation in sex chromosomes and autosomes

Peter A. Moran, Sonia Pascoal, Timothée Cezard, Judith E. Risse, Michael G. Ritchie & Nathan W. Bailey
Linking intraspecific and interspecific divergence is an important challenge in speciation research. X chromosomes are expected to evolve faster than autosomes and disproportionately contribute to reproductive barriers, and comparing genetic variation on X and autosomal markers within and between species can elucidate evolutionary processes that shape genome variation. We performed RADseq on a 16-population transect of two closely-related Australian cricket species, Teleogryllus commodus and T. oceanicus, covering allopatry and sympatry. This classic study system for...

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: Brassicales phylogeny inferred from 72 plastid genes: a reanalysis of the phylogenetic localization of two paleopolyploid events and origin of novel chemical defenses

Patrick P. Edger, Jocelyn C. Hall, Alex Harkess, Michelle Tang, Jill Coombs, Setareh Mohammadin, M. Eric Schranz, Zhiyong Xiong, James Leebens-Mack, Blake C. Meyers, Kenneth J. Systma, Marcus A. Koch, Ihsan A. Al-Shehbaz, J. Chris Pires & Kenneth J. Sytsma
PREMISE OF THE STUDY - Previous phylogenetic studies employing molecular markers have yielded various insights into the evolutionary history across Brassicales, but many relationships between families remain poorly supported or unresolved. A recent phylotranscriptomic approach utilizing 1155 nuclear markers obtained robust estimates for relationships among 14 of 17 families. Here we report a complete family‐level phylogeny estimated using the plastid genome. METHODS - We conducted phylogenetic analyses on a concatenated data set comprising 44,926 bp...

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: 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...

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: 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...
