Alicia Valdés, Jonathan Lenoir, Pieter De Frenne, Emilie Andrieu, Jorg Brunet, Olivier Chabrerie, Sara Cousins, Marc Deconchat, Pallieter De Smedt, Martin Diekmann, Steffen Ehrmann, Emilie Gallet-Moron, Stefanie Gaertner, Brice Giffard, Karin Hansen, Martin Hermy, Annette Kolb, Vincent Leroux, Jaan Liira, Jessica Lindgren, Ludmilla Martin, Tobias Naaf, Taavi Paal, Willem Proesmans, Michael Scherer-Lorenzen … & Guillaume Decocq
Global forest loss and fragmentation have strongly increased the frequency of forest patches smaller than a few hectares. Little is known about the biodiversity and ecosystem service supply potential of such small woodlands in comparison to larger forests. As it is widely recognized that high biodiversity levels increase ecosystem functionality and the delivery of multiple ecosystem services, small, isolated woodlands are expected to have a lower potential for ecosystem service delivery than large forests hosting...

A historical-genetic reconstruction of human extra-pair paternity

Maarten H.D. Larmuseau, Pieter Van Den Berg, Sofie Claerhout, Francesc Calafell, Alessio Boattini, Leen Gruyters, Michiel Vandenbosch, Kelly Nivelle, Ronny Decorte & Tom Wenseleers
Paternity testing using genetic markers has shown that extra-pair paternity (EPP) is common in many pair-bonded species. Evolutionary theory and empirical data show that extra-pair copulations can increase the fitness of males as well as females. This can carry a significant fitness cost for the social father, who then invests in rearing offspring that biologically are not his own. In human populations, the incidence and correlates of extra-pair paternity remain highly contentious. Here, we use...

Relationship of total and calculated free 25-hydroxyvitamin D to biomarkers and metabolic indices in healthy children

Christine Simpson, Jane Zhang, Dirk Vanderschueren, Lei Fu, Teresita Pennestri, Roger Bouillon, David Cole & Thomas Carpenter
ABSTRACT Context: Vitamin D status is usually assessed by serum total 25-hydroxyvitamin D. Whether free 25-hydroxyvitamin D measures better correlate with various clinical outcomes is unclear. Objective: To identify correlations between total 25-hydroxyvitamin D (t25-OHD), calculated and direct measures of free 25-OHD, and to identify associations of these measures with other outcomes in children, across the 6 common GC haplotypes. Design: Healthy urban-dwelling children underwent measurement of relevant variables. Setting: Academic medical center Participants: Healthy,...

Tree diversity is key for promoting the diversity and abundance of forest‐associated taxa in Europe

Eric Allan, Evy Ampoorter, Luc Barbaro, Hervé Jactel, Lander Baeten, Johanna Boberg, Monique Carnol, Bastien Castagneyrol, Yohan Charbonnier, Seid Muhie Dawud, Marc Deconchat, Pallieter De Smedt, Hans De Wandeler, Virginie Guyot, Stephan Hättenschwiler, François‐Xavier Joly, Julia Koricheva, Harriet Milligan, Bart Muys, Diem Nguyen, Sophia Ratcliffe, Karsten Raulund‐Rasmussen, Michael Scherer‐Lorenzen, Fons Plas, J. Van Keer … & Lars Vesterdal
Plant diversity is an important driver of diversity at other trophic levels, suggesting that cascading extinctions could reduce overall biodiversity. Most evidence for positive effects of plant diversity comes from grasslands. Despite the fact that forests are hotspots of biodiversity, the importance of tree diversity, in particular its relative importance compared to other management related factors, in affecting forest‐associated taxa is not well known. To address this, we used data from 183 plots, located in...

Challenges in Using OSM for Robotic Applications

Nico Huebel, Sebastian Blumenthal, Lakshadeep Naik & Herman Bruyninckx
This work discusses how to use OSM for robotic applications and aims at starting a discussion between the OSM and the robotics community. OSM contains much topological and semantic information that can be directly used in robotics and offers various advantages: 1) Standardized format with existing tooling. 2) The graph structure allows to compose the OSM models with domain-specific semantics by adding custom nodes, relations, and key-value pairs. 3) Information about many places is already...

Data from: Latitudinal variation in mycorrhizal diversity associated with a European orchid

Karl J. Duffy, Michael Waud, Bertrand Schatz, Theodora Petanidou & Hans Jacquemyn
Aim: Biodiversity is known to be unevenly distributed along latitudinal gradients. While this pattern has been observed for many different organisms, it is unclear whether the distributions of ecologically important belowground mutualists, such as orchid mycorrhizal fungi (OMF), also vary according to latitude. Location: Europe. Methods: We sampled 37 populations over a 3000 km latitudinal gradient of the European orchid Spiranthes spiralis to test whether the diversity and community composition of OMF are influenced by...

Data from: Areal differences in depth cue integration between monkey and human

Marcelo Armendariz, Hiroshi Ban, Andrew E Welchman & Wim Vanduffel
Electrophysiological evidence suggested primarily the involvement of area MT in depth cue integration in macaques, as opposed to human imaging data pinpointing area V3B/KO. To clarify this conundrum, we decoded monkey fMRI responses evoked by stimuli signaling near or far depths defined by binocular disparity, relative motion and their combination, and we compared results with those from an identical experiment previously performed in humans.Responses in macaque area MT are more discriminable when two cues concurrently...

Data from: Long-term impacts of changed grazing regimes on the vegetation of heterogeneous upland grasslands

Robin J. Pakeman, Debbie A. Fielding, Liese Everts & Nick A. Littlewood
Marginal agricultural land, which in the UK refers particularly to upland grazings, will see changes in management driven by markets, subsidies, grants and environmental change with implications for biodiversity. Using a large-scale, long-term grazing experiment in the UK uplands we assessed the impact of intensification (tripling sheep numbers), abandonment (removal of sheep) and grazer diversification (partial replacement of sheep by cattle) on vegetation composition in a heterogenous area of grassland. Species benefiting from increased grazing...

Data from: Single-cell selectivity and functional architecture of human lateral occipital complex

Thomas Decramer, Elsie Premereur, Mats Uytterhoeven, Wim Van Paesschen, Johannes Van Loon, Peter Janssen & Tom Theys
The human lateral occipital complex (LOC) is more strongly activated by images of objects compared to scrambled controls, but detailed information at the neuronal level is currently lacking. We recorded with microelectrode arrays in the LOC of two patients, and obtained highly selective single-unit, multi-unit and high-gamma responses to images of objects. Contrary to predictions derived from functional imaging studies, all neuronal properties indicated that the posterior subsector of LOC we recorded from occupies an...

Data from: In silico study of the role of cell growth factors in photosynthesis using a virtual leaf tissue generator coupled to a microscale photosynthesis gas exchange model

Moges Retta, Metadel Abera, Herman Berghuijs, Pieter V, Paul C Struik & Bart Nicolai
Computational tools that allow in silico analysis of the role of cell growth and division on photosynthesis are scarce. We present a freely available tool that combines a virtual leaf tissue generator and a two-dimensional microscale model of gas transport during C3 photosynthesis. A total of 270 mesophyll geometries were generated with varying degree of growth anisotropy, growth extent and extent of schizogenous airspace formation in the palisade mesophyll. The anatomical properties of the virtual...

Data from: Type Maastrichtian gastropod faunas evidencing rapid ecosystem recovery following the Cretaceous-Palaeogene boundary

Johan Vellekoop, Kris Van Tilborgh, Paul Van Knippenberg, John Jagt, Peter Stassen, Stijn Goolaerts & Robert Speijer
The study of the global mass extinction event at the Cretaceous–Palaeogene (K/Pg) boundary can aid in understanding patterns of selective extinction and survival, and dynamics of ecosystem recovery. Outcrops in the Maastrichtian type area (southeast Netherlands, northeast Belgium) comprise an exceptionally expanded K/Pg boundary succession that offers a unique opportunity to study marine ecosystem recovery within the first thousands of years following the mass extinction event. A quantitative analyses was performed on systematically sampled macrofossils...

A series of failures to replicate amnesia for contextual fear memories in rats by systemic administration of several drugs after memory retrieval.

Multiverse Analysis of Data from Preregistered Study - toward Preregistered Multiverse Analysis

Dominik Lenda & wolf vanpaemel
We discussed the shortcomings of two crucial research practices which aim at reducing the influence of researcher degrees of freedom on statistical results, preregistration and multiverse analysis. We employed a multiverse analysis using data from a preregistered study, showing that preregistration may still hide arbitrariness in data processing. We argue that the best solution is to combine both, in a preregistered multiverse analysis. This project is described in the poster which was presented at the...

Cross-activity of honeybee queen pheromones in bumblebees provides evidence for sensory exploitation

Sarah A. Princen, Annette Van Oystaeyen, Clément Petit, Jelle S. Van Zweden & Tom Wenseleers
The evolutionary origin of queen pheromones, which regulate reproductive division of labor in insect societies, has been explained by two evolutionary scenarios: the sender-precursor hypothesis and the sensory exploitation hypothesis. These scenarios differ in terms of whether the signaling system was built on preadaptations on the part of either the sender queens or the receiver workers. While some social insect queen pheromones – such as cuticular hydrocarbons – were likely derived from ancestral fertility cues...

The Politics of Globalization

Helena Kreuter
Over the past three decades, trade with low-wage countries - in first place China - has grown dramatically. Economic theory has long recognized that trade liberalization, though enlarging the overall economic pie, also produces strong redistributive effects: while it increases aggregate productivity and benefits consumers through lower prices and a wider range of available goods, at the same time it is also associated with substantial adjustment costs in the labour market. As the gains are...

Data from: Rapid evolution in response to warming does not affect the toxicity of a pollutant: insights from experimental evolution in heated mesocosms

Chao Zhang, Mieke Jansen, Luc De Meester & Robby Stoks
While human-induced stressors such as warming and pollutants may co-occur and interact, evolutionary studies typically focus on single stressors. Rapid thermal evolution may help organisms better deal with warming, yet it remains an open question whether thermal evolution changes the toxicity of pollutants under warming. We investigated the effects of exposure to a novel pollutant (zinc oxide nanoparticles, nZnO) and 4°C warming (20°C vs 24°C) on key life history and physiological traits of the water...

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...

Explaining illness with evil: Pathogen prevalence fosters moral vitalism

Brock Bastian, Christin-Melanie Vauclair, Steve Loughnan, Paul Bain, Ashwini Ashokkumar, Maja Becker, Michal Bilewicz, Emma Collier-Baker, Carla Crespo, Paul W. Eastwick, Ronald Fischer, Malte Friese, Ángel Gómez, Valeschka M. Guerra, Jose Luis Castellanos Guevara, Katja Hanke, Nic Hooper, Li-Li Huang, Shi Junqi, Minoru Karasawa, Peter Kuppens, Siri Leknes, Müjde Peker, Cesar Pelay, Afoditi Pina … & William B. Swann
Pathogens represent a significant threat to human health leading to the emergence of strategies designed to help manage their negative impact. We examined how spiritual beliefs developed to explain and predict the devastating effects of pathogens and spread of infectious disease. Analysis of existing data in Studies 1 and 2 suggests that moral vitalism (beliefs about spiritual forces of evil) is higher in geographical regions characterized by historical higher levels of pathogens. Furthermore, drawing on...
