Speech Disfluencies as Actual and Believed Cues to Deception: Individuality of Liars and the Collective of Listeners

Nette Vandenhouwe & Robert J. Hartsuiker
There is no consensus about the relationship between disfluencies and deception in speech production. However, it is well established that listeners believe deceptive speech to contain more disfluencies than truthful speech. Here, we used an interactive game to collect the speech of liars and the veracity decisions of listeners. Using Multivariate Pattern Analysis (MVPA), we determined the predictive value of speech disfluencies as both actual and believed cues to deception. We found that patterns of...

Time-Varying Effects of Oil Supply Shocks on the U.S. Economy

Baumeister Christiane & Gert Peersman
We use vector autoregressions with drifting coefficients and stochastic volatility to investigate how the dynamic effects of oil supply shocks on the U.S. economy have changed over time. We find a substantial decline in the short-run price elasticity of oil demand since the mid-eighties. This finding helps explain why an oil production shortfall of the same magnitude is associated with a stronger response of oil prices and more severe macroeconomic consequences over time, while an...

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: 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...

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...

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....

Word-form related disfluency versus lemma related disfluency: an exploratory analysis of disfluency patterns in connected-speech production

Aurélie Pistono & Robert J. Hartsuiker
Several language production levels may be involved in the production of disfluencies. In the current study, we conducted network task experiments to tackle disfluencies related to conceptualization, which we operationalized by impeding visual object recognition (i.e. blurring). Contrary to what was expected, blurriness did not lead to more disfluency. However, disfluency type and disfluency location were closely related. This suggests a distinction in the underlying function of disfluencies, some reflecting word-form related difficulties, others reflecting...

Decane 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 decane 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, 0fw). The total flow rate was kept constant at...

Data from: Thermal differences between juveniles and adults increased over time in European forest trees

Maria Mercedes Caron, Florian Zellweger, Kris Verheyen, Lander Baeten, Radim Hédl, Bernhardt-Römermann Markus, Imre Berki, Jörg Brunet, Guillaume Decocq, Sandra Díaz, Thomas Dirnböck, Tomasz Durak, Thilo Heinken, Bogdan Jaroszewicz, Martin Kopecký, Jonathan Lenoir, Martin Macek, Malicki Marek, František Máliš, Thomas Nagel, Michael Perring, Petr Petřík, Kamila Reczyńska, Remigiusz Pielech, Wolfgang Schmidt … & Pieter De Frenne
Woody species’ requirements and environmental sensitivity change from seedlings to adults, a process referred to as ontogenetic shift. Such shifts can be increased by climate change. To assess the changes in the difference of temperature experienced by seedlings and adults in the context of climate change, it is essential to have reliable climatic data over long periods that capture the thermal conditions experienced by the individuals throughout their life cycle. Here we used a unique...

Data from: Resource predictability drives inter-annual variation in migratory behaviour in a long-lived bird

Jan Baert, Eric Stienen, Frederick Verbruggen, Nico Van De Weghe, Luc Lens & Wendt Müller
There is a growing awareness that experience may play a major role in migratory decisions, especially in long-lived species. However, empirical support remains to date scarce. Here, we use multi-year GPS-tracking data on 28 adult Lesser Black-backed Gulls (Larus fuscus), a long-lived species for which migratory strategies typically consist of a series of long stopovers, to assess how experience affects interannual variation in stopover selection. We expect that food source reliability should play a pivotal...

The database contains the results of DNA metabarcoding (sequences, relative importances) and microscopy pollen count data.

The Role of Time-Varying Price Elasticities in Accounting for Volatility Changes in the Crude Oil Market

Christiane Baumeister & Gert Peersman
There has been a systematic increase in the volatility of the real price of crude oil since 1986, followed by a decline in the volatility of oil production since the early 1990s. We explore reasons for this evolution. We show that a likely explanation of this empirical fact is that both the short-run price elasticities of oil demand and of oil supply have declined considerably since the second half of the 1980s. This implies that...

Untangling the structural and molecular mechanisms underlying colour and rapid colour change in a lizard, Agama atra

Michael Nicolai, Liliana D'Alba, Jonathan Goldenberg, Yannick Gansemans, Filip Van Nieuwerbrugh, Susana Clusella-Trullas & Matthew Shawkey
With functions as diverse as communication, protection and thermoregulation, colouration is one of the most important traits in lizards. The ability to change colour as a function of varying social and environmental conditions is thus an important innovation. While colour change is present in animals ranging from squids, to fish and reptiles, not much is known about the mechanisms behind it. Traditionally, colour change was attributed to migration of pigments, in particular melanin. More recent...

Dataset for: Molecular diversity of dragonflies in high altitude Andean lakes through DNA barcoding

Alonzo Alfaro-Núñez, Rodrigo Chiriboga-Ortega, Christine Van Der Heyden, Maria Eugenia Sulen Burgos, Sania Ortega, Tania Oña, Elizabeth Velarde & Peter Goethals
Genetic and morphological identification of dragonflies’ larvae species in three high elevation Andean tropical lakes was done using DNA barcoding of the cytochrome oxidase 1 gene (COI). Phylogeny allowed inferring the evolutionary relationships of at least 5 species (from 74 samples) that belong to two different families within the Odonata order.

Global change shifts trade-offs among ecosystem functions in woodlands restored for multifunctionality

Sebastian Fiedler, José Monteiro, Kristin Hulvey, Rachel Standish, Michael Perring & Britta Tietjen
1. Ecological restoration increasingly aims at improving ecosystem multifunctionality and making landscapes resilient to future threats, especially in biodiversity hotspots such as Mediterranean-type ecosystems. Plants and their traits play a major role in the functioning of an ecosystem. Therefore, successful restoration towards long-term multifunctionality requires a fundamental mechanistic understanding of this link under changing climate. An integrated approach of empirical research and simulation modelling with a focus on plant traits can allow this understanding. 2....

Springtail coloration at a finer scale: mechanisms behind vibrant Collembolan metallic colours

Bram Vanthournout, Anastasia Rousaki, Thomas Parmentier, Frans Janssens, Johan Mertens, Peter Vandenabeele, Liliana D'Alba & Matthew Shawkey
The mechanisms and evolution of metallic structural colours are of both fundamental and applied interest, yet most work in arthropods has focused on derived butterflies and beetles with distinct hues. In particular, basal hexapods - groups with many scaled, metallic representatives – are currently poorly studied and controversial, with some recent studies suggesting either that thin- film (lamina thickness) or diffraction grating elements (longitudinal ridges, crossribs) produce these colors in early Lepidoptera and one springtail...

Data-Linking remote sensing data to the estimation of pollination services in agroecosystems

Daniel Ariza, Ivan Meeus, Maxime Eeraerts, Matti Pisman & Guy Smagghe
Wild bees are key providers of pollination services in agroecosystems. The abundance of these pollinators, and the service they provide, relies on the availability of supporting resources in the landscape. Because of this, spatially explicit models have been developed to quantify wild bee abundance and pollination services in food crops, while accounting for the influence of locally available foraging and nesting resources. However, model implementation is limited by the availability of land cover maps and...

Inhibitory control, exploration behaviour and manipulated ecological context are associated with foraging flexibility in the great tit

Jenny Coomes, Gabrielle Davidson, Michael Reichert, Ipek Kulahci, Camille Troisi & John Quinn
​​​​​Organisms are constantly under selection to respond effectively to diverse, sometimes rapid, changes in their environment, but not all individuals are equally plastic in their behaviour. Although cognitive processes and personality are expected to influence individual behavioural plasticity, the effects reported are highly inconsistent, which we hypothesise is because ecological context is usually not considered. We explored how one type of behavioural plasticity, foraging flexibility, was associated with inhibitory control (assayed using a detour-reaching task)...

Data to: Enjoying tranquility - Development of ground vegetation after cessation of management in forests on loamy soils in Flanders (Belgium)

Kris Vandekerkhove, Arno Thomaes, Luc De Keersmaeker, Peter Van De Kerckhove, Thierry Onkelinx, Hans Van Calster & Kris Verheyen
Questions: Managed forests often show a more homogeneous age structure compared to untouched forests, but also a higher share and frequency of sun-exposed conditions due to harvest operations. Frequent, small-scaled forestry operations may therefore lead to elevated species richness, compared to undisturbed forests. When non-intervention is introduced in formerly managed forests, Is there a significant decrease in species richness of vascular plant species? What species are particularly affected? Are there nonrandom shifts in species composition?...
