Data from: Children in the Syrian civil war: the familial, educational, and public health impact of ongoing violence

Abdallah Mohamed Elsafti, Gerlant Van Berlaer, Mohammad Al Safadi, Michel Debacker, Ronald Buyl, Atef Redwan & Ives Hubloue
The Syrian civil war since 2011 has led to one of the most complex humanitarian emergencies in history. The objective of this study was to document the impact of the conflict on the familial, educational, and public health state of Syrian children. A cross-sectional observational study was conducted in May 2015. Health care workers visited families with a prospectively designed data sheet in 4 Northern Syrian governorates. The 1001 children included in this study originated...

Microsatellite data of Avicennia marina from Gazi Bay, Kenya

Ludwig Triest
Mangrove ecosystems along the East African coast are often characterized by a disjunct zonation of seaward and landward Avicennia marina. This disjunct zonation may be maintained through different positions in the tidal frame, yielding different dispersal settings. The spatial configuration of the landscape and coastal processes such as tides and waves are expected to largely influence the extent of propagule transport and subsequent regeneration. We hypothesized that landward sites would keep a stronger genetic structure...

Data from: A ketocarotenoid-based color polymorphism in the Sira poison frog Ranitomeya sirensis indicates novel gene interactions underlying aposematic signal variation

Evan Twomey, James Johnson, Santiago Castroviejo-Fisher & Ines Van Bocxlaer
The accumulation of red ketocarotenoids is an important component of coloration in many organisms, but the underlying mechanisms are poorly understood. In some organisms, ketocarotenoids are sequestered from the diet and can accumulate when enzymes responsible for carotenoid breakdown are disrupted. In other organisms, ketocarotenoids are formed endogenously from dietary precursors via oxidation reactions carried out by carotenoid ketolase enzymes. Here, we study the genetic basis of carotenoid coloration in an amphibian. We demonstrate that...

Dynamic feedbacks among tree functional traits, termite populations and deadwood turnover

Chao Guo, Bin Tuo, Ci Hang, Enrong Yan & Johannes H. C. Cornelissen
1. Changes in the composition of plant functional traits may affect ecosystem processes through influencing trophic interactions. Bottom-up control by plant species through food availability to animals may vary with time. However, such dynamics and their consequences for deadwood turnover are poorly known for detrital food webs. 2. We introduce a dynamic conceptual model of the feedback of (deadwood-feeding) termite populations, tree functional traits and deadwood decomposition. We hypothesized that tree functional diversity (in terms...

Data from: Integrative taxonomy of root-knot nematodes reveals multiple independent origins of mitotic parthenogenesis

Toon Janssen, Gerrit Karssen, Olivera Topalović, Danny Coyne & Wim Bert
During sampling of several Coffea arabica plantations in Tanzania severe root galling, caused by a root-knot nematode was observed. From pure cultures, morphology and morphometrics of juveniles and females matched perfectly with Meloidogyne africana, whereas morphology of the males matched identically with those of Meloidogyne decalineata. Based on their Cox1 sequence, however, the recovered juveniles, females and males were confirmed to belong to the same species, creating a taxonomic conundrum. Adding further to this puzzle,...

Data from: Functional diversity and structural disorder in the human ubiquitination pathway

Pallab Bhowmick, Rita Pancsa, Mainak Guharoy & Peter Tompa
The ubiquitin-proteasome system plays a central role in cellular regulation and protein quality control (PQC). The system is built as a pyramid of increasing complexity, with two E1 (ubiquitin activating), few dozen E2 (ubiquitin conjugating) and several hundred E3 (ubiquitin ligase) enzymes. By collecting and analyzing E3 sequences from the KEGG BRITE database and literature, we assembled a coherent dataset of 563 human E3s and analyzed their various physical features. We found an increase in...

Data from: A refugee camp in the center of Europe: clinical characteristics of asylum seekers arriving in brussels

Gerlant Van Berlaer, Francisca Bohle Carbonell, Sofie Manantsoa, Xavier De Béthune, Ronald Buyl, Michel Debacker & Ives Hubloue
Background In the summer of 2015, the exodus of Syrian war refugees and saturation of refugee camps in neighboring countries led to the influx of asylum-seekers in European countries, including Belgium. This study aims to describe the demographic and clinical characteristics of asylum-seekers that arrived in a huddled refugee camp, in the center of a well-developed country with all medical facilities. Methods Using a descriptive cross-sectional study design, physicians of Médecins du Monde prospectively registered...

Data from: What caused over a century of decline in general intelligence? Testing predictions from the genetic selection and neurotoxin hypotheses

Michael A. Woodley Of Menie, Matthew A. Sarraf, Mateo Peñaherrera-Aguirre, Heitor B.F. Fernandes & David Becker
Several converging lines of evidence indicate that general intelligence (g) has declined in Western populations. The causes of these declines are debated. Here, two hypotheses are tested: (1) selection acting against genetic variants that promote g causes the decline and (2) the presence of neurotoxic pollution in the environment causes the decline. A linear mixed model was devised to test (1) and (2), in which the secular decline in a “heritable g” (g.h) chronometric factor...

Hidden hybridization and habitat differentiation ina Mediterranean macrophyte, the euryhaline genus Ruppia

Lise Beirinckx, Bram Vanschoenwinkel & Ludwig Triest
In many aquatic plant taxa, classification and identification based on morphology has always been difficult. Molecular markers revealed that the complexity in several of these aquatic taxa could be addressed to recurrent hybridization events and cryptic species diversity. The submerged macrophyte genus Ruppia is one of these aquatic genera with a complex taxonomy due to the absence of clear distinguishable traits and several hybridization events. Two species co-exist throughout Europe, R. maritima and R. spiralis...

Data from: Do people imitate when making decisions? - evidence from a spatial prisoners dilemma experiment

Jelena Grujic & Tom Lenaerts
How do people decide which action to take? This question is best answered using Game Theory, which has proposed a series of decision mechanisms that people potentially use. In network simulations, wherein games are repeated and payoff differences can be observed, those mechanisms rely often on imitation of successful behavior. Surprisingly, little to no evidence has been provided about whether, how and what people actually use to alter their actions in that context. By comparing...

Microsatellite genotypes and ITS2 DNA sequence data for Seriatopora hystrix

Rosa Maria Van Der Ven, Jean-François Flot, Carol Buitrago-López & Marc Kochzius
Coral reefs provide essential goods and services but are degrading at an alarming rate due to local and global anthropogenic stressors. The main limitation that prevents the implementation of adequate conservation measures is that connectivity and genetic structure of populations are poorly known. Here, the genetic diversity and connectivity of the brooding scleractinian coral, Seriatopora hystrix were assessed at two scales by genotyping ten microsatellite markers for 356 individual colonies. Seriatopora hystrix showed high differentiation,...

Data from: Prey colonization in freshwater landscapes can be stimulated or inhibited by the proximity of remote predators

Beth Turner, Hendrik Trekels, Mathil Vandromme & Bram Vanschoenwinkel
1. Recent findings suggest that the colonization of habitat patches may be affected by the quality of surrounding patches. For instance, patches that lack predators may be avoided when located near others with predators, a pattern known as risk contagion. Alternatively, predator avoidance might also redirect dispersal towards nearby predator-free patches resulting in so-called habitat compression. However, it is largely unknown how predators continue to influence these habitat selection behaviors at increasing distances from outside...

Data from: Towards a common methodology for developing logistic tree mortality models based on ring-width data

Maxime Cailleret, Christof Bigler, Harald Bugmann, J. Julio Camarero, Katarina Cufar, Hendrik Davi, Ilona Mészáros, Francesco Minunno, Mikko Peltoniemi, Elisabeth Robert, María-Laura Suarez, Roberto Tognetti & Jordi Martinez-Vilalta
Tree mortality is a key process shaping forest dynamics. Thus, there is a growing need for indicators of the likelihood of tree death. During the last decades, an increasing number of tree-ring based studies have aimed to derive growth–mortality functions, mostly using logistic models. The results of these studies, however, are difficult to compare and synthesize due to the diversity of approaches used for the sampling strategy (number and characteristics of alive and death observations),...

Data from: The influence of balanced and imbalanced resource supply on biodiversity-functioning relationship across ecosystems

Aleksandra M. Lewandowska, Antje Biermann, Elizabeth T. Borer, Miguel A. Cebrian-Piqueras, Steven A. J. Declerck, Luc De Meester, Ellen Van Donk, Lars Gamfeldt, Daniel S. Gruner, Nicole Hagenah, W.

Lind, Elena Litchman, Jasmin Mantilla-Contreras, Koen Martens, Sandra Meier, Vanessa Minden, Joslin L. Moore, Harry Olde Venterink, Eric W. Seabloom … & Helmut Hillebrand
Numerous studies show that increasing species richness leads to higher ecosystem productivity. This effect is often attributed to more efficient portioning of multiple resources in communities with higher numbers of competing species, indicating the role of resource supply and stoichiometry for biodiversity–ecosystem functioning relationships. Here, we merged theory on ecological stoichiometry with a framework of biodiversity–ecosystem functioning to understand how resource use transfers into primary production. We applied a structural equation model to define patterns...

Objective: Morphine is a commonly used drug in encephalopathic neonates treated with therapeutic hypothermia after perinatal asphyxia. Pharmacokinetics and optimal dosing of morphine in this population are largely unknown. The objective of this study was to describe pharmacokinetics of morphine and its metabolites morphine-3-glucuronide and morphine-6-glucuronide in encephalopathic neonates treated with therapeutic hypothermia and to develop pharmacokinetics based dosing guidelines for this population. Study design: Term and near-term encephalopathic neonates treated with therapeutic hypothermia and...

Serum 25(OH)D level on hospital admission is correlated with COVID-19 mortality

Geert Martens
Objective: Vitamin D deficiency was previously correlated with incidence and severity of COVID-19. We investigated the correlation between serum 25(OH)D level on admission and radiological stage and outcome of COVID-19 pneumonia. Methods: Retrospective observational trial on 186 SARS-CoV-2-infected individuals hospitalized from March 1, 2020 to April 7, 2020 with combined chest CT and 25(OH)D measurement on admission. Multivariate analysis was performed to study if vitamin D deficiency (25(OH)D < 20 ng/mL) predicts survival independently of...

Data from: The ancient Britons: groundwater fauna survived extreme climate changes over tens of millions of years across NW Europe

Caitríona E. McInerney, Louise Maurice, Anne L. Robertson, Lee R. F. D. Knight, Jörg Arnscheidt, Chris Venditti, James S. G. Dooley, Thomas Mathers, Severine Matthijs, Karin Eriksson, Graham S. Proudlove & Bernd Hänfling
Global climate changes during the Cenozoic (65.5 - 0 Ma) caused major biological range shifts and extinctions. In Northern Europe, for example, a pattern of few endemics and the dominance of wide-ranging species is thought to have been determined by the Pleistocene (2.59 – 0.01 Ma) glaciations. This study, in contrast, reveals an ancient subsurface fauna endemic to Britain and Ireland. Using a Bayesian phylogenetic approach we found that two species of stygobitic invertebrates (genus...

Data from: Humans recognize emotional arousal in vocalizations across all classes of terrestrial vertebrates: evidence for acoustic universals

Piera Filippi, Jenna V. Congdon, John Hoang, Daniel Liu Bowling, Stephan A. Reber, Andrius Pašukonis, Marisa Hoeschele, Sebastian Ocklenburg, Bart De Boer, Christopher B. Sturdy, Albert Newen & Onur Gunturkun
Writing over a century ago, Darwin hypothesized that vocal expression of emotion dates back to our earliest terrestrial ancestors. If this hypothesis is true, we should expect to find cross-species acoustic universals in emotional vocalizations. Studies suggest that acoustic attributes of aroused vocalizations are shared across many mammalian species, and that humans can use these attributes to infer emotional content. But do these acoustic attributes extend to non-mammalian vertebrates? In this study, we asked human...

Data from: Integrated culturing, modeling and transcriptomics uncovers complex interactions and emergent behavior in a three-species synthetic gut community

Kevin D'hoe, Stefan Vet, Karoline Faust, Frédéric Moens, Gwen Falony, Didier Gonze, Verónica Lloréns-Rico, Lendert Gelens, Jan Danckaert, Luc De Vuyst & Jeroen Raes
Whereas the composition of the human gut microbiome is well resolved, predictive understanding is still lacking. Here, we followed a bottom-up strategy to explore human gut community dynamics: we established a synthetic community composed of three representative human gut isolates (Roseburia intestinalis L1-82, Faecalibacterium prausnitzii A2-165 and Blautia hydrogenotrophica S5a33) and explored their interactions under well-controlled conditions in vitro. Systematic mono- and pair-wise fermentation experiments confirmed competition for fructose and cross-feeding of formate. We quantified...

Data from: A stoichiometric perspective of the effect of herbivore dung on ecosystem functioning

Judith Sitters & Harry Olde Venterink
Ungulate herbivores play a prominent role in maintaining the tree–grass balance in African savannas. Their top-down role through selective feeding on either trees or grasses is well studied, but their bottom-up role through deposition of nutrients in dung and urine has been overlooked. Here, we propose a novel concept of savanna ecosystem functioning in which the balance between trees and grasses is maintained through stoichiometric differences in dung of herbivores that feed on them. We...

Mechanisms for color convergence in a mimetic radiation of poison frogs

Evan Twomey, Morgan Kain, Myriam Claeys, Kyle Summers, Santiago Castroviejo-Fisher & Ines Van Bocxlaer
In animals, bright colors often evolve to mimic other species when a resemblance is selectively favored. Understanding the proximate mechanisms underlying such color mimicry can give insights into how mimicry evolves, for example, whether color convergence evolves from a shared set of mechanisms or through the evolution of novel color production mechanisms. We studied color production mechanisms in poison frogs (Dendrobatidae), focusing on the mimicry complex of Ranitomeya imitator. Using reflectance spectrometry, skin pigment analysis,...
