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 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: A prioritised list of invasive alien species to assist the effective implementation of EU legislation

Carles Carboneras, Piero Genovesi, Montserrat Vila, Tim Blackburn, Martina Carrete, Miguel Clavero, Bram D'hondt, Jorge F. Orueta, Belinda Gallardo, Pedro Geraldes, Pablo González-Moreno, Richard D. Gregory, Wolfgang Nentwig, Jean-Yves Paquet, Petr Pysek, Wolfgang Rabitsch, Iván Ramírez, Riccardo Scalera, Jose Tella, Paul Walton, Robin Wynde & Tim M. Blackburn
1. Effective prevention and control of invasive species generally relies on a comprehensive, coherent and representative list of species that enables resources to be used optimally. European Union (EU) Regulation 1143/2014 on invasive alien species (IAS) aims to control or eradicate priority species, and to manage pathways to prevent the introduction and establishment of new IAS; it applies to species considered of Union concern and subject to formal risk assessment. So far, 49 species have...

Data from: Kinematics of chisel-tooth digging by African mole-rats

Sam Van Wassenbergh, Stef Heindryckx & Dominique Adriaens
Mole-rats are known to use their protruding, chisel-like incisors to dig underground networks of tunnels, but it remains unknown how these incisors are used to break and displace the soil. Theoretically, different excavation strategies can be used. Mole-rats could either use their head depressor muscles to power scooping motions of the upper incisors (by nose-down head rotations) or the lower incisors (by nose-up head rotations), or their jaw adductors to grab and break the soil...

Data from: Covert deformed wing virus infections have long-term deleterious effects on honeybee foraging and survival

Kristof Benaets, Anneleen Van Geystelen, Dries Cardoen, Lina De Smet, Dirk C. De Graaf, Liliane Schoofs, Maarten H.D. Larmuseau, Laura E. Brettell, Stephen J. Martin, Tom Wenseleers & Maarten H. D. Larmuseau
Several studies have suggested that covert stressors can contribute to bee colony declines. Here we provide a novel case study and show using radiofrequency identification tracking technology that covert deformed wing virus (DWV) infections in adult honeybee workers seriously impact long-term foraging and survival under natural foraging conditions. In particular, our experiments show that adult workers injected with low doses of DWV experienced increased mortality rates, that DWV caused workers to start foraging at a...

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: microCT-based phenomics in the zebrafish skeleton reveals virtues of deep phenotyping in a distributed organ system

Matthew Hur, Charlotte A. Gistelinck, Philippe Huber, Jane Lee, Marjorie H. Thompson, Adrian T. Monstad-Rios, Claire J. Watson, Sarah K. McMenamin, Andy Willaert, David M. Parichy, Paul Coucke & Ronald Y. Kwon
Phenomics, which ideally involves in-depth phenotyping at the whole-organism scale, may enhance our functional understanding of genetic variation. Here, we demonstrate methods to profile hundreds of phenotypic measures comprised of morphological and densitometric traits at a large number of sites within the axial skeleton of adult zebrafish. We show the potential for vertebral patterns to confer heightened sensitivity, with similar specificity, in discriminating mutant populations compared to analyzing individual vertebrae in isolation. We identify phenotypes...

Data from: Mammalian herbivores affect leafhoppers associated with specific plant functional types at different timescales

Martijn L. Vandegehuchte, Valeria Trivellone, Martin Schütz, Jennifer Firn, Frederic De Schaetzen & Anita C. Risch
1. Theory predicts that mammalian herbivores affect the quantity and quality of plants on which they preferentially feed in the short term. In the longer term, they can promote either preferred or less preferred plants, depending on whether preferred plants are adapted or sensitive to grazing. Less clear are the short- and long-term responses of herbivorous insects to mammalian herbivory, and how these responses depend on the specific plants or plant functional types on which...

Data from: Urbanization-driven changes in web-building and body size in an orb-web spider

Maxime Dahirel, Maarten De Cock, Pieter Vantieghem & Dries Bonte
1. In animals, behavioural responses may play an important role in determining population persistence in the face of environmental changes. Body size is a key trait central to many life history traits and behaviours. Correlations with body size may constrain behavioural variation in response to environmental changes, especially when size itself is influenced by environmental conditions. 2. Urbanization is an important human-induced rapid environmental change that imposes multiple selection pressures on both body size and...

Data from: Genetic patterns in Neotropical Magnolias (Magnoliaceae) using de novo developed microsatellite markers

Emily Veltjen, Pieter Asselman, Majela Hernández Rodríguez, Alejandro Palmarola Bejerano, Ernesto Testé Lozano, Luis Roberto González Torres, Paul Goetghebeur, Isabel Larridon & Marie-Stéphanie Samain
Conserving tree populations safeguards forests since they represent key elements of the ecosystem. The genetic characteristics underlying the evolutionary success of the tree growth form: high genetic diversity, extensive gene flow and strong species integrity, contribute to their survival in terms of adaptability. However, different biological and landscape contexts challenge these characteristics. This study employs 63 de novo developed microsatellite or SSR (Single Sequence Repeat) markers in different datasets of nine Neotropical Magnolia species. The...

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...

Data from: WisecondorX: improved copy number detection for routine shallow whole-genome sequencing

Lennart Raman, Annelies Dheedene, Matthias De Smet, Jo Van Dorpe & Björn Menten
Shallow whole-genome sequencing to infer copy number alterations (CNAs) in the human genome is rapidly becoming the method par excellence for routine diagnostic use. Numerous tools exist to deduce aberrations from massive parallel sequencing data, yet most are optimized for research and often fail to redeem paramount needs in a clinical setting. Optimally, a read depth-based analytical software should be able to deal with single-end and low-coverage data—this to make sequencing costs feasible. Other important...

Data from: Using archived television video footage to quantify phenology responses to climate change

Pieter De Frenne, Lisa Van Langenhove, Alain Vandriessche, Cedric Bertrand, Kris Verheyen & Pieter Vangansbeke
Predicting how the timing of cyclic life‐history events, such as leafing and flowering, respond to climate change is of paramount importance due to the cascading impacts of vegetation phenology on species and ecosystem fitness. However, progress of this field is hampered by the relative scarcity, and geographic and phylogenetic bias, of long‐term phenology datasets. By taking advantage of archived television video footage, we here developed an innovative tool using previously unexploited records to build long‐term...

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...

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...

Nitrogen and brine injected into Estaillades carbonate - steady-state experiments

Catherine Spurin, Samuel Krevor, Martin Blunt & Tom Bultreys
This data is micro-CT images of the simultaneous injection of nitrogen and brine into a porous carbonate rock (Estaillades). The images were acquired during steady-state, which was deduced from a plateau in the differential pressure across the sample. The experiments were conducted in the capillary dominated regime (the total flow rate was kept constant, with the fractional flow (fw) changed in sequence 0.85fw, 0.7fw, 0.5fw, 0.25fw, 0.03fw, 0fw). There is the high Ca experiment where...

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...

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...

Caulerpa-associated bacterial 16S rRNA in response to environmental stress

Kathryn Morrissey
This dataset contains data from algal-associated bacteria from the green macroalgae, Caulerpa, from the paper " Morrissey, K.L. et al. (2021) Impacts of environmental stress on resistance and resilience of algal-associated bacterial communities. Ecology and Evolution". The experiment investigates the effects of a factorial combination of nutrient and temperature stress on the bacterial communities. We have also assessed the resistance and resilience of the algal-associated microbiota to environmental stress, using community dissimilarity metrics. Bacteria were...

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....

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....

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...

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...
