Pourquoi les femmes occupent-elles moins de postes à responsabilité ? Une analyse des promotions universitaires en économie (Policy Brief, n°14)

Clément Bosquet, Pierre-Philippe Combes & Cecilia Garcia-Penalosa
Si les écarts entre les hommes et les femmes de taux d'emploi global et de salaires, à caractéristiques observables données, dont le type d'emploi, sont devenus très faibles, il n'en reste pas moins que les femmes occupent moins fréquemment des postes à haute responsabilité, mieux rémunérés. Notre étude sur le monde académique français en sciences économiques montre que les femmes ne sont pas discriminées lors des concours de promotion mais qu'elles postulent de 30 à...

Data from: Evidence for a genetic sex determination in Cnidaria, the Mediterranean red coral (Corallium rubrum)

Marine Pratlong, Anne Haguenauer, Sandrine Chenesseau, Kelly Brener, Guillaume Mitta, Eve Toulza, M. Bonabaud, S. Rialle, Didier Aurelle & Pierre Pontarotti
Sexual reproduction is widespread among eukaryotes, and the sex-determining processes vary greatly among species. While genetic sex determination (GSD) has been intensively described in bilaterian species, no example has yet been recorded among non-bilaterians. However, the quasi-ubiquitous repartition of GSD among multicellular species suggests that similar evolutionary forces can promote this system, and that these forces could occur also in non-bilaterians. Studying sex determination across the range of Metazoan diversity is indeed important to understand...

Data from: TAF4, a subunit of transcription factor II D, directs promoter occupancy of nuclear receptor HNF4A during post-natal hepatocyte differentiation

Daniil Alpern, Diana Langer, Benoit Ballester, Stephanie Le Gras, Christophe Romier, Gabrielle Mengus & Irwin Davidson
The functions of the TAF subunits of mammalian TFIID in physiological processes remain poorly characterised. Here we describe a novel function of TAFs in directing genomic occupancy of a transcriptional activator. Using liver-specific inactivation in mice, we show that the TAF4 subunit of TFIID is required for post-natal hepatocyte maturation. TAF4 promotes pre-initiation complex (PIC) formation at post-natal expressed liver function genes and down-regulates a subset of embryonic expressed genes by increased RNA polymerase II...

Data from: Introducing resprouters to enhance Mediterranean forest resilience: importance of functional traits to select species according to a gradient of pine density

Jordane Gavinet, Bernard Prévosto & Catherine Fernandez
Resprouter species are important for Mediterranean ecosystem resilience, but they are scarce in landscapes dominated by pioneer pines. Sound knowledge of resprouter seedling functional responses and establishment success across different pine habitats would help guide forest restoration efforts. Four broadleaved resprouter species, that is two shrubs – Arbutus unedo and Pistacia terebinthus – and two trees – Fraxinus ornus and Sorbus domestica – were planted under an experimentally created gradient of pine cover from totally...

Des débats autour de questions scientifiques socialement vives : quelles conduites argumentatives et compétences cognitives pour des élèves ingénieurs ?

Fatma Saïd Touhami, Céline Besançon, Simon Lanher, Valérie Desjardin & Laurence Dupont
L’intégration de problématiques liées au développement durable dans la formation des futurs ingénieurs amène à traiter des questions scientifiques socialement vives (QSSV) dans le cœur de l’enseignement. Dans la mesure où les QSSV sont interdisciplinaires (Simonneaux, 2008), leur enseignement nécessite la mise en œuvre de dispositifs pédagogiques et didactiques favorisant l’inter et la transdisciplinarité. Des recherches didactiques ont mis l’accent sur la pertinence de deux formes d’enseignement majeurs que sont les projets interdisciplinaires et les...

Data from: Seasonal variability of groundwater level effects on the growth of Carex cinerascens in lake wetlands

Wenjuan Feng, Pierre Mariotte, Xu Ligang, Alexandre Buttler, Luca Bragazza, Jiahu Jiang & Mathieu Santonja
Groundwater level is crucial for wetland plant growth and reproduction, but the extent of its effect on plant growth can vary along with changed precipitation and temperature at different seasons. In this context, we investigated the effect of two groundwater levels (10 cm vs. 20 cm depth) on growth and reproductive parameters of Carex cinerascens, a dominant plant species in the Poyang Lake wetland, during three seasons (spring, summer and autumn) and during two consecutive...

Conservation genetics of Armeria belgenciencis

Alex Baumel, Frédéric Médail, Marianick Juin, Thibault Paquier, Marie Clares, Perrine Laffargue, Hélène Lutard, Lara Dixon & Mathias Pires
This the data set of the paper "Population genetic structure and management perspectives for Armeria belgenciencis, a narrow endemic plant from Provence (France)" published in Plant Ecology and Evolution: ###############. The genetic structure of Armeria belgenciensis and geographically close populations of Armeria arenaria was analyzed on the basis of 328 AFLP markers using model-based and model-free clustering methods. In addition, flowering phenology was estimated to address the possibility of pre-zygotic isolation between A. belgenciensis and...

Impact of smoking cessation, coffee and bread consumption on the intestinal microbial composition among Saudis: A cross-sectional study

Steve Harakeh, Ghada Ajabnoor, Sulaiman Alfadul, Suhad Bahijri, Turki Al Amri, Dipankar Bachar, Timokratis Karamitros, Suha Farraj, Emmanouil Angelakis, Ahmed Al-Hejin, Raoult Didier, Ahmed Mirza, Esam Azhar & Abdalla Ahmed
The gut microbiota is often affected by the dietary and lifestyle habits of the host, resulting in a better efficacy that favors energy harvesting from the consumed food. Our objective was to characterize the composition of gut microbiota in adult Saudis and investigate possible association with lifestyle and dietary practices. Feces from 104 Saudi volunteers (48% males) were tested for microbiota by sequencing the V3-V4 region of bacterial 16S ribosomal RNA (rRNA). For all participants,...

Redox controls RecA protein activity via reversible oxidation of its methionine residues

Benjamin Ezraty, Camille Henry, Frederic Barras, Laurent Loiseau, Alexandra Vergnes, Didier Vertommen, Angela Mérida-Floriano, Sindhu Chitteni-Pattu, Elizabeth Anne Wood, Josep Casadesús & Michael M. Cox
Reactive oxygen species (ROS) cause damage to DNA and proteins. The RecA protein plays a central role in the bacterial response to DNA damage. Here we report that RecA itself is also targeted by ROS. In vivo consequences of RecA oxidation include defects in SOS induction, DNA repair efficiency, and P1 transduction. In vitro, oxidized RecA fails to display ATPase activity, DNA strand exchange capacity and formation of nucleofilaments. Consistently, mass spectrometry analysis of oxidized...

Threatened salmon rely on a rare life history strategy in a warming landscape

Flora Cordoleani, Corey Phillis, Anna Sturrock, Alyssa FitzGerald, George Whitman, Anthony Malkassian, Peter Weber & Rachel Johnson
Rare phenotypes and behaviours within a population are often overlooked, yet they may serve a heightened role for species imperilled by rapid warming. In threatened spring-run Chinook salmon spawning at the southern edge of the species range, we show late-migrating juveniles are critical to cohort success in years characterized by droughts and ocean heatwaves. Late migrants rely on cool river temperatures over summer, increasingly rare due to the combined effects of warming and impassable dams....

Supplementary data for: From genomics to integrative taxonomy? The case study of Pocillopora corals

Nicolas Oury, Cyril Noel, Stefano Mona, Didier Aurelle & Hélène Magalon
With the advent of genomics, sequencing thousands of loci from hundreds of individuals now appears feasible at reasonable costs, allowing complex phylogenies to be resolved. This is particularly relevant for cnidarians, for which insufficient data due to the small number of currently available markers, coupled with difficulties in inferring gene trees and morphological incongruences, encrypts species boundaries, thereby blurring the study and conservation of these organisms. Yet, can genomics alone be used to delimit species...
