Data and code for: Replay of innate vocal patterns during sleep in suboscines

Juan Francisco Döppler, Manon Peltier, Ana Amador, Franz Goller & Gabriel Mindlin
Activation of forebrain circuitry during sleep has been variably characterized as ‘pre- or replay’ and has been linked to memory consolidation. The evolutionary origins of this mechanism, however, are unknown. Sleep activation of the sensori-motor pathways of learned birdsong is a particularly useful model system because the muscles controlling the vocal organ are activated, revealing syringeal activity patterns for direct comparison with those of day-time vocal activity. Here we show that suboscine birds, which develop...

Analyses on the fungus-farming termite, Macrotermes natalensis

Mark Harrison, Mireille Vassuer-Cognet, Sarah Seite, David Sillam-Dussès, Roland Lupoli, Alain Robert, Laure-Anne Poissonnier, Tom Van Dooren, Arnaud Lemainque, David Renault, Sebastien Acket, Muriel Andrieu, Jose Viscarra, Hei Sook Sul, Wilhelm De Beer & Erich Bornberg-Bauer
Kings and queens of eusocial termites can live for decades, while queens sustain a nearly maximal fertility. To investigate the molecular mechanisms underlying their long lifespan, we carried out transcriptomics, lipidomics and metabolomics in Macrotermes natalensis on sterile short-lived workers, long-lived kings and five stages spanning twenty years of adult queen maturation. Reproductives share gene expression differences from workers in agreement with a reduction of several aging-related processes, involving upregulation of DNA damage repair and...

Genotypes and their interaction effects on reproduction and mating-induced immune activation in Drosophila melanogaster

Claudia Fricke, Sergio Ávila-Calero & Sophie Armitage
Mating causes considerable alterations in female physiology and behaviour, and immune gene expression, partly due to proteins transferred from males to females during copulation. The magnitude of these phenotypic changes could be driven by the genotypes of males and females, as well as their interaction. To test this, we carried out a series of genotype by genotype (G × G) experiments using Drosophila melanogaster populations from two distant geographical locations. We expected lines to have...

ddRAD-derived genotypes of Centaurea jacea and Betonica officinalis populations from the White Carpathians

Johannes Höfner, Theresa Klein-Raufhake, Christian Lampei, Ondrej Mudrak, Anna Bucharova & Walter Durka
Ecological restoration and plant re-introductions aim to create plant populations that are genetically similar to natural populations to preserve the regional gene pool, yet genetically diverse to allow adaptation to a changing environment. For this purpose, seeds for restoration are increasingly sourced from multiple populations in the target region. However, it has only rarely been tested whether using regional seed indeed leads to genetically diverse restored populations which are genetically similar to natural populations. We...

Pollinator community predicts trait-matching between oil-producing flowers and a guild of oil-collecting bees

Hilke Hollens-Kuhr, Timotheüs Van Der Niet, Ruth Cozien & Michael Kuhlmann
The impact of pollinator community diversity on trait-matching in plant-pollinator interactions is poorly studied, even though many mutualisms involve multiple interaction partners. We studied ten communities in which one to three species of oil-collecting Rediviva bee pollinate the long-spurred, oil-producing flowers of Diascia ‘floribunda’ to examine how pollinator diversity affects covariation of functional traits across sites and trait-matching within sites. Floral spur-length was significantly correlated with weighted grand mean foreleg length of the local bee...

Data from: Potentially peat-forming biomass of fen sedges increases with increasing nutrient levels

Tjorven Hinzke, Guixiang Li, Franziska Tanneberger, Elke Seeber, Camiel Aggenbach, Jelena Lange, Łukasz Kozub, Klaus-Holger Knorr, Juergen Kreyling & Wiktor Kotowski
Peat formation is a key carbon sequestration process in the terrestrial biosphere. In temperate fens, peat is mainly formed by below-ground biomass of vascular plants. Nutrient availability in temperate fens is naturally variable, and nowadays increasing due to atmospheric deposition, runoff from agriculture, and mineralization of peat caused by drainage. To maintain or restore peat formation, it is important to understand how increased nutrient availability influences the main controls of peat formation, i.e., below-ground biomass...

Data from: Different frequency control mechanisms and the exploitation of frequency space in passerines

Franz Goller, Jay Love & Gabriel Mindlin
1. Birdsong is used in reproductive context and, consequently, has been shaped by strong natural and sexual selection. The acoustic performance includes a multitude of acoustic and temporal characteristics that are thought to honestly reveal the quality of the singing individual. 2. One major song feature is frequency and its modulation. Sound frequency can be actively controlled, but the control mechanisms differ between different groups. Two described mechanisms are pressure-driven frequency changes in suboscines and...

Soil microbial biomass and enzyme kinetics for the assessment of temporal diversification in agroecosystems

Ute Hamer, Michael Ulrich Thomas Meyer, Ulf-Niklas Meyer, Anja Radermacher, Philipp Götze, Heinz-Josef Koch & Christoph Scherber
In agroecosystems, temporal diversification creates a sequence of short-lived habitats through time. Crop species as well as the diversity of crops grown in sequence might affect soil biodiversity and nutrient cycling processes. In the present study, we focused on a long-term crop rotation established in 2006 in Lower Saxony, Germany on a Luvisol. Winter wheat (WW) and silage maize (SM) were grown in continuous cultivation as well as in rotations. WW rotations span up to...

Data from: The stochastic dynamics of early epidemics: probability of establishment, initial growth rate, and infection cluster size at first detection

Peter Czuppon, Emmanuel Schertzer, François Blanquart & Florence Débarre
Emerging epidemics and local infection clusters are initially prone to stochastic effects that can substantially impact the epidemic trajectory. While numerous studies are devoted to the deterministic regime of an established epidemic, mathematical descriptions of the initial phase of epidemic growth are comparatively rarer. Here, we review existing mathematical results on the epidemic size over time, and derive new results to elucidate the early dynamics of an infection cluster started by a single infected individual....

Abstract We report the inclusion of carboxy- and amine-substituted molecular nanodiamonds (NDs) adamantane, diamantane, and triamantane by β-cyclodextrin and γ-cyclodextrin (β-CD and γ-CD), which h...

Data from: Plant provenance affects pollinator network: implications for ecological restoration

Anna Bucharova, Christian Lampei, Malte Conrady, Janis Matheja, Emilia May, Michael Meyer & David Ott
The selection of plant provenance for ecological restoration is an intensively debated topic. Throughout this debate, arguments mostly focus on plant performance, but little attention is paid to the effects of provenance on other members of the restored ecosystem. On the other hand, in restoration projects that focus specifically on supporting interacting biota, for example, flower stripes among fields to support pollinators, the provenance choice is often not considered, partly because the effect of provenance...

Data from: The representational dynamics of perceived voice emotions evolve from categories to dimensions

Bruno L. Giordano, Caroline Whiting, Nikolaus Kriegeskorte, Sonja A. Kotz, Joachim Gross & Pascal Belin
Long-standing affective science theories conceive the perception of emotional stimuli either as discrete categories (for example, an angry voice) or continuous dimensional attributes (for example, an intense and negative vocal emotion). Which position provides a better account is still widely debated. Here we contrast the positions to account for acoustics-independent perceptual and cerebral representational geometry of perceived voice emotions. We combined multimodal imaging of the cerebral response to heard vocal stimuli (using functional magnetic resonance...

Data from: Comparative transcriptomic analysis of the mechanisms underpinning ageing and fecundity in social insects

Judith Korb, Karen Meusemann, Denise Aumer, Abel Bernadou, Daniel Elsner, Barbara Feldmeyer, Susanne Foitzik, Jürgen Heinze, Romain Libbrecht, Silu Lin, Megha Majoe, José Manuel Monroy Kuhn, Volker Nehring, Matteo A. Negroni, Robert J. Paxton, Alice C. Séguret, Marah Stoldt & Thomas Flatt
Exceptional longevity of social insect queens despite their lifelong high fecundity remains poorly understood in ageing biology. To gain insights into the mechanisms that might underlie ageing in social insects, we compared gene expression patterns between young and old castes (both queens and workers) across different lineages of social insects (two termite, two bee and two ant species). After global analyses, we paid particular attention to genes of the insulin/insulin-like growth factor 1 signalling (IIS)/target...

Data from: A global perspective on the functional responses of stream communities to flow intermittence

Julie Crabot, Cédric P. Mondy, Philippe Usseglio-Polatera, Ken M. Fritz, Paul J. Wood, Michelle J. Greenwood, Michael T. Bogan, Elisabeth I. Meyer & Thibault Datry
The current erosion of biodiversity is a major concern that threatens the ecological integrity of ecosystems and the ecosystem services they provide. Due to global change, an increasing proportion of river networks are drying and changes from perennial to non-perennial flow regimes represent dramatic ecological shifts with potentially irreversible alterations of community and ecosystem dynamics. However, there is minimal understanding of how biological communities respond functionally to drying. Here, we highlight the taxonomic and functional...

The evolution of size-dependent competitive interactions promotes species coexistence

Jaime Mauricio Anaya-Rojas, Ronald D Bassar, Tomos Potter, Allison Blanchette, Shay Callahan, Nick Framstead, David Reznick & Joseph Travis
1. Theory indicates that competing species coexist in a community when intraspecific competition is stronger than interspecific competition. When body size determines the outcome of competitive interactions between individuals, coexistence depends also on how resource use and the ability to compete for these resources change with body size. Testing coexistence theory in size-structured communities, therefore, requires disentangling the effects of size-dependent competitive abilities and niche shifts. 2. Here, we tested the hypothesis that the evolution...
