Data from: Contributions of feather microstructure to eider down insulation properties

Liliana D'Alba, Thomas Holm Carlsen, Árni Ásgeirsson, Matthew D. Shawkey & Jon Einar Jonsson
Insulation is an essential component of nest structure that helps provide incubation requirements for birds. Many species of waterfowl breed in high latitudes where rapid heat loss can necessitate a high energetic input from parents and use down feathers to line their nests. Common eider Somateria mollissima nest down has exceptional insulating properties but the microstructural mechanisms behind the feather properties have not been thoroughly examined. Here, we hypothesized that insulating properties of nest down...

Data from: Stressor fluxes alter the relationship between beta-diversity and regional productivity

Jonathan De Raedt, Jan M. Baert, Colin R. Janssen & Frederik De Laender
Dispersal of organisms can influence the relationship between beta-diversity and regional productivity in heterogeneous environments. However, many ecosystems are also linked by fluxes of stressors, with an unknown influence on this relationship. In this study, we assess the relationship between beta-diversity (measured as Bray-Curtis dissimilarity) and regional productivity (measured as biovolume) under various levels of a stressor flux in meta-ecosystems that were composed of two marine micro-algae communities. We created heterogeneity by exposing one of...

Because You Had a Bad Day: General and Daily Relations between Reactive Temperament, Emotion Regulation, and Depressive Symptoms in Youth

Marie-Lotte Van Beveren, Sofie Kuppens, Benjamin Hankin & Caroline Braet
Negative emotionality (NE) and positive emotionality (PE) have repeatedly shown to act as vulnerability factors for youth depression. Less research examined the mechanisms through which these reactive temperament traits may differently confer vulnerability to depression. Based on recent integrated models of depression proposing emotion regulation as a key underlying mechanism, the current study aimed to clarify the general and day-to-day relations among temperament, emotion regulation strategies, and depressive symptoms in Dutch-speaking youth (35% boys; M_age...

A preliminary field trial to compare control techniques for invasive Berberis aquifolium in Belgian coastal dunes

Tim Adriaens, Pieter Verschelde, Emma Cartuyvels, Bram D'hondt, Edward Vercruysse, Wouter Van Gompel, Evy Dewulf & Sam Provoost
Non-native Berberis aquifolium is notoriously invasive in Belgian coastal dunes. With its strong clonal growth through suckers, this evergreen shrub outcompetes native species and affects dune succession. To prevent further secondary spread and mitigate its impact, there was an urgent need for knowledge on the effectiveness of control measures, both at the plant and habitat level. Here, we report on a first control experiment. Individual B. aquifolium clones were subjected to one of four treatments...

Data from: Induced phenological avoidance: a neglected defense mechanism against seed predation in plants

Bram Sercu, Iris Moeneclaey, Dries Bonte & Lander Baeten
1. Flowering phenology is an important life history trait affecting plant reproductive performance and is influenced by various abiotic and biotic factors. Pre-dispersal seed predation and pollination are expected to impose counteracting selection pressure on flowering phenology, with pre-dispersal seed predation expected to favor off-peak flowering and pollination to favor synchronous flowering. 2. Here we studied the effect of pre-dispersal seed predation by the beetle Byturus ochraceus, a specialist seed herbivore, on the flowering phenology...

Forest microclimate dynamics drive plant responses to warming

Florian Zellweger, Pieter De Frenne & David Coomes
Climate warming is causing a shift in biological communities in favor of warm-affinity species (i.e., thermophilisation). However, species responses often lag behind climate warming and local microclimates modulated by vegetation and topography are usually ignored. Here we analyze multidecadal understorey microclimate dynamics in European forests and show that thermophilisation and the climatic lag in forest plant communities are primarily controlled by microclimate. Increasing tree canopy cover reduces warming rates inside forests, but loss of canopy...

Species-specific effects of thermal stress on the expression of genetic variation across a diverse group of plant and animal taxa under experimental conditions

Klaus Fischer, Jürgen Kreyling, Michaël Beaulieu, Ilka Beil, Manuela Bog, Dries Bonte, Stefanie Holm, Sabine Knoblauch, Dustin Koch, Lena Muffler, Pierick Mouginot, Maria Paulinich, J.F. Scheepens, Raijana Schiemann, Jonas Schmeddes, Martin Schnittler, Gabriele Uhl, Marieke Van Der Maaten-Theunissen, Julia M. Weier, Martin Wilmking, Robert Weigel & Phillip Gienapp
Assessing the genetic adaptive potential of populations and species is essential for better understanding evolutionary processes. However, the expression of genetic variation may depend on environmental conditions, which may speed up or slow down evolutionary responses. Thus, the same selection pressure may lead to different responses. Against this background, we here investigate the effects of thermal stress on genetic variation, mainly under controlled laboratory conditions. We estimated additive genetic variance (VA), narrow-sense heritability (h2), and...

Chytrid Fungi and Nitrile Gloves Research Data

Valarie Thomas, Pascale Van Rooij, Celine Meerpoel, Gwij Stegen, Jella Wauters, Lynn Vanhaecke, An Martel & Frank Pasmans
To prevent transmission of the pathogenic chytrid fungi Batrachochytrium dendrobatidis (Bd) and Batrachochytrium salamandrivorans (Bsal), hygiene protocols prescribe the single use of disposable gloves for handling amphibians. We discovered that rinse water from nitrile gloves instantly kills 99% of Bd and Bsal zoospores. Transmission experiments using midwife toads (Alytes obstetricans) and Bd, and Alpine newts (Ichthyosaura alpestris) and Bsal, show that the use of the same pair of gloves for 2 subsequent individuals does not...

Dataset for: Aboveground carbon stocks, woody and litter productivity along an elevational gradient in the Rwenzori Mountains, Uganda

Joseph Okello, Marijn Bauters, Hans Verbeeck, John Kasenene & Pascal Boeckx
Montane forests are characterized by high biodiversity, endemism and strong elevational environmental gradients. The latter attribute makes them also suitable as a ‘natural laboratory’ for studying the effects of environmental parameters on ecosystem functions. To provide better insight into the carbon cycle of Afromontane ecosystems, we used an elevational gradient approach to quantify carbon stocks, woody and litter productivity, and their constraining factors. Twenty plots were established, covering five elevations from Kibale Forest at 1250...

Simultaneous genotyping of snails and infecting trematode parasites using high-throughput amplicon sequencing.

Cyril Hammoud, Stephen Mulero, Bert Van Bocxlaer, Jérôme Boissier, Dirk Verschuren, Christian Albrecht & Tine Huyse
Several methodological issues currently hamper the study of entire trematode communities within populations of their intermediate snail hosts. Here we develop a new workflow using high-throughput amplicon sequencing to simultaneously genotype snail hosts and their infecting trematode parasites. We designed primers to amplify 4 snail and 5 trematode markers in a single multiplex PCR. While also applicable to other genera, we focused on medically and economically important snail genera within the Superorder Hygrophila and targeted...

A metacommunity approach for detecting species influenced by mass effect

Thibault Leboucher, Juliette Tison-Rosebery, William R. Budnick, Aurélien Jamoneau, Wim Vyverman, Janne Soininen, Sébastien Boutry & Sophia I. Passy
1. Mass effect, allowing species to persist in unfavourable habitats, and dispersal limitation, preventing species from reaching favourable habitats, are the two major dispersal processes. While dispersal limitation can be detected by experimental or modeling techniques, mass effect is more challenging to evaluate, which hampers our ability to disentangle the influence of the environment vs. dispersal on species distribution. This is undesirable for biomonitoring programs built on known species-environment relationships. 2. We developed an approach...

Data from: Canonical correlations reveal adaptive loci and phenotypic responses to climate in perennial ryegrass

José L. Blanco-Pastor, Philippe Barre, Thomas Keep, Thomas Ledauphin, Abraham Escobar-Gutiérrez, Anna Maria Roschanski, Evelyn Willner, Klaus Dehmer, Matthew Hegarty, Hilde Muylle, Elisabeth Veeckman, Klaas Vandepoele, Tom Ruttink, Isabel Roldán-Ruiz, Stéphanie Manel & Jean-Paul Sampoux
Germplasm from perennial ryegrass (Lolium perenne L.) natural populations is useful for breeding because of its adaptation to a wide range of climates. Climate-adaptive genes can be detected from associations between genotype, phenotype and climate but an integrated framework for the analysis of these three sources of information is lacking. We used two approaches to identify adaptive loci in perennial ryegrass and their effect on phenotypic traits. First, we combined Genome-Environment Association (GEA) and GWAS...

Data from: Alternative food sources interfere with removal of a fungal amphibian pathogen by zooplankton

Arne Deknock, Frank Pasmans, Robby Van Leeuwenberg, Sarah Van Praet, Stijn Bruneel, Luc Lens, Siska Croubels, An Martel & Peter Goethals
1. While the amphibian disease chytridiomycosis is causing ongoing population declines and biodiversity losses around the globe, efficient mitigation strategies are lacking. The free-living zoospores of the causative agents of this disease, the chytrid pathogens Batrachochytrium dendrobatidis (Bd) and Batrachochytrium salamandrivorans (Bsal), are a potential food source for filter-feeding micropredators as part of the aquatic food web. While consumption of zoospores can lower environmental pathogen loads, alternative food sources may interfere with pathogen removal rates....

Data from: A brief history and popularity of methods and tools used to estimate micro-evolutionary forces

Jonathan Kidner, Panagiotis Theodorou, Martin Husemann, Jan Engler & Martin Taubert
Population genetics is a field of research that predates the current generations of sequencing technology. Those approaches, that were established before massively parallel sequencing methods, have been adapted to these new marker systems (in some cases involving the development of new methods) that allow genome-wide estimates of the four major micro-evolutionary forces – mutation, gene flow, genetic drift and selection. Nevertheless, classic population genetic markers are still commonly used and a plethora of analysis methods...

The concurrent assessment of agronomic, ecological, and environmental variables enables better choice of agroecological service crop termination management

David Navarro-Miró, José M. Blanco-Moreno, Corrado Ciaccia, Elena Testani, Ileana Iocola, Laura Depalo, Giovanni Burgio, Hanne Lakkenborg Kristensen, Margita Hefner, Kalvi Tamm, Ingrid Bender, Alessandro Persiani, Mariangela Diacono, Francesco Montemurro, Koen Willekens, Hélène Védie, Martina Bavec, Martina Robačer, Donatienne Arlotti, Pauline Deltour, Stefaan De Neve, Mesfin Tsegaye Gebremikael, Lourdes Chamorro, Berta Caballero-López, Alejandro Pérez-Ferrer … & F. Xavier Sans
1. Although organic farming was originally promoted as an alternative farming system to address agronomic, environmental, and ecological issues, its conventionalisation has led to an intensification and specialisation of production. In light of this, several studies have questioned the environmental benefits of organic farming as well as its agronomic viability. Thus, there is a need to improve organic vegetable systems to reduce their environmental impact without affecting their productivity. To tackle this challenge, European farmers...

We have also assessed the resistance and resilience of the algal-associated microbiota to environmental stress, using community dissimilarity metrics. Bacteria were...

Nematodes community composition and environmental parameters, Eastern Antarctic Peninsula

Gabriella Panto, Francesca Pasotti, Lara Macheriotou & Ann Vanreusel
This study provides a snapshot of the largely understudied meiobenthic and nematode communities in the Prince Gustav Channel and Duse Bay. We compared five stations sampled at different water depths along the shelf and investigated their meiobenthic community structure. We approached nematode biodiversity comparing traditional taxonomic identification and high throughput sequencing (HTS), with the use of Amplicon Sequence Variants (ASVs). Additionally, we characterized the environment by primary production proxies, grain size and seasonal ice conditions....

Functional trait variation of Anemone nemorosa along macro‐ and microclimatic gradients close to the northern range edge

Leen Depauw, Ri Hu, Khumanand S. Dhungana, Sanne Govaert, Camille Meeussen, Pieter Vangansbeke, Richard Strimbeck, Bente J. Graae & Pieter De Frenne
Climate warming is affecting ecosystems worldwide, and slow-colonizing forest under- storey species are particularly vulnerable if they are unable to track climate change. However, species’ responses to climatic conditions in terms of growth, reproduction and colonization capacity may vary with the distance to their distribution range edge. Anemone nemorosa is known to be a slow colonizing forest herb dependent on forest cover in the southern and central part of its distribution range, whereas at its...

Effects of losses disguised as wins on response vigor - Experiment 3

Zhang Chen, Charlotte Eben & Frederick Verbruggen
In two previous experiments, we found that losses disguised as wins (LDWs, i.e., 'winning' part of one's wager back) had a distinct influence on response vigor compared to both regular wins and regular losses. However, some potentially confounding factors still existed. In the current experiment, we use a new design to address these issues.

Peter Lauwers, Katia Paykin, Mihaela ILIOAIA, Machteld Meulleman & Pascale Hadermann
This volume brings together about twenty contributions on the syntax and semantics of predicates and arguments, written by international specialists in the field. The formal architecture of the predicate (verbal and nominal) and the morpho-syntactic means of marking its arguments are addressed, with particular attention to the dative. This book is mainly focused on French, while putting it in perspective with other languages, Romance (Spanish, Romanian), Germanic (Dutch, English) and Slavic (Russian), not to mention...

Large-Eddy Simulations of T-shaped Open-Channel Confluences With Different Downstream Channel Widths

Pedro Xavier Ramos, Laurent Schindfessel, João Pedro Pêgo & Tom De Mulder
Confluences of open-channel flows are common in nature as well as in urban drainage networks and in hydraulic structures. The complex hydrodynamics is often studied in schematized, right-angled confluences. In this paper, the influence of the downstream channel width onto time-averaged and turbulent flow features will be investigated numerically, based on Large-Eddy Simulations. For one flow situation, i.e. flow ratio and downstream Froude number, two geometries will be compared: a discordant width case, which was...
