Data from: Resource use and food preferences in understorey ant communities along a complete elevational gradient in Papua New Guinea

Jerome Orivel, Petr Klimes, Vojtech Novotny & Maurice Leponce
Elevational gradients provide an interesting opportunity for studying the effect of climatic drivers over short distances on the various facets of biodiversity. It is globally assumed that the decrease in species richness with increasing elevation follows mainly the decrease in ecosystem productivity, but studies on functional diversity still remain limited. Here, we investigated how resource use and food preferences by both individual ant species and communities foraging in the understorey vary with elevation along a...

Data from: Acute liver dysfunction after cardiac arrest

Enrica Iesu, Federico Franchi, Federica Zama Cavicchi, Selene Pozzebon, Vito Fontana, Manuel Mendoza, Leda Nobile, Sabino Scolletta, Jean-Louis Vincent, Jacques Creteur & Fabio Silvio Taccone
Few data are available regarding hypoxic hepatitis (HH) and acute liver failure (ALF) in patients resuscitated from cardiac arrest (CA). The aim of this study was to describe the occurrence of these complications and their association with outcome. All adult patients admitted to the Department of Intensive Care following CA were considered for inclusion in this retrospective study. Exclusion criteria were early death (<24 hours) or missing biological data. We retrieved data concerning CA characteristics...

Data from: Towards the description of livestock mobility in Sahelian Africa: some results from a survey in Mauritania

Understanding spatio-temporal patterns of host mobility is a key factor to prevent and control animal and human diseases. This is utterly important in low-income countries, where animal disease epidemics have strong socio-economic impacts. In this article we analyzed a livestock mobility database, whose data have been collected by the Centre National d’Elevage et de Recherches Vétérinaires (CNERV) Mauritania, to describe its patterns and temporal evolution. Data were collected through phone and face-to-face interviews in almost...

Data from: Testing and interpreting the shared space-environment fraction in variation partitioning analyses of ecological data

David Bauman, Jason Vleminckx, Olivier J. Hardy & Thomas Drouet
Variation partitioning analyses combined with spatial predictors (Moran’s eigenvector maps, MEM) are commonly used in ecology to test the fractions of species abundance variation purely explained by environment and space. However, while these pure fractions can be tested using a classical residuals permutation procedure, no specific method has been developed to test the shared space-environment fraction (SSEF). Yet, the SSEF is expected to encompass a major driver of community assembly, that is, an induced spatial...

Data from: Food dissemination in ants: robustness of the trophallactic network against resource quality

Olivier Bles, Jean-Louis Deneubourg & Stamatios C. Nicolis
Insect societies are often composed of many individuals, achieving collective decisions that depend on environmental and colonial characteristics. For example, ants are able to focus their foraging effort on the most rewarding food source. While this phenomenon is well known, the link between the food source quality and the intranidal food dissemination networks and its dynamics has been neglected. Here we analysed the global dynamics of the food dissemination in Camponotus cruentatus workers, after feeding...

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: Symmetry breaking and inter-clonal behavioural variability in slime molds

David Vogel, Audrey Dussutour & Jean-Louis Deneubourg
Cells are dynamic systems capable of switching from an isotropic growth to a polarized growth even in the absence of any pre-existing external asymmetry. Here, we study this process of symmetry breaking in the acellular slime mold Physarum polycephalum. In the experiments slime molds could grow on two identical opposed sources of calcium. We highlighted a positive correlation between growth dynamic, level of symmetry breaking and calcium concentration. We identified three populations of slime molds...

Data from: Sex ratio variations among years and breeding systems in a facultatively parthenogenetic termite

Simon Hellemans, Denis Fournier, Robert Hanus & Yves Roisin
Some species of termites evolved an outstanding reproductive strategy called asexual queen succession (AQS), in which the primary queen is replaced by multiple parthenogenetically produced daughters (neotenics) that mate with the primary king. When the primary king is eventually replaced, this time by sexually produced neotenic king(s), sex-asymmetric inbreeding occurs and the queen’s genome is more transmitted than that of the king, thereby increasing the reproductive value of female dispersers, and female-biased population sex ratio...
