Better residential than ethnic discrimination! Reconciling audit's findings and interviews' findings in the Parisian housing market (LIEPP Working Paper, n°36)

Francois Bonnet, Etienne Lalé, Mirna Safi & Etienne Wasmer
This article investigates discrimination and the interplay of residential and ethnic stigma on the French housing market using two different methods, paired-testing au- dit study of real estate agencies and face-to-face interviews with real estate agents. The juxtaposition of their findings leads to a paradox: interviews reveal high levels of ethnic discrimination but little to none residential discrimination, while the audit study shows that living in deprived suburbs is associated with a lower probability of...

La comparaison dans Philandre (1544) Procédures figuratives en contexte narratif

Pascale Mounier
La comparaison participe à l'élaboration des types de texte en s'adaptant aux contraintes formelles des genres et aux principes de la production des discours, qui évoluent dans le temps. Elle joue en l'occurrence plusieurs rôles dans l'élaboration des séquences narratives de Philandre, un roman de chevalerie composé par Jean des Gouttes et publié en 1544. Une double approche de linguistique textuelle et de stylistique historique permet d'identifier trois grandes procédures figuratives à l'oeuvre dans les...

Data from: Species Selection Regime and Phylogenetic Tree Shape

George Verboom, Florian Boucher, David Ackerly, Lara Wootton & William Freyman
Species selection, the effect of heritable traits in generating between-lineage diversification rate differences, provides a valuable conceptual framework for understanding the relationship between traits, diversification and phylogenetic tree shape. An important challenge, however, is that the nature of real diversification landscapes – curves or surfaces which describe the propensity of species-level lineages to diversify as a function of one or more traits – remains poorly understood. Here we present a novel, time-stratified extension of the...

Grounding line of Denman Glacier, East Antarctica from satellite radar interferometry

Virginia Brancato, Eric Rignot, Pietro Milillo, Mathieu Morlighem, Jeremie Mouginot, Lu An, Bernd Scheuchl, Seong Su Jeong, Paola Rizzoli, Jose Luiz Bueso Bello & Pau Prats-Iraola
Grounding line, elevation changes, and melt rates maps of Denman Glacier, East Antarctica. Using satellite radar interferometry from the COSMO-SkyMed mission we map the grounding line of Denman Glacier, East Antarctica. We complement these data with some historical interferometric radar acquisition from the European satellite ERS-1/2. We present new maps of elevation changes on the grounded and floating portions of Denman Glacier obtained by temporally differencing TanDEM-X Digital Elevation Models.

Continued adaptation of C4 photosynthesis after an initial burst of changes in the Andropogoneae grasses

Matheus Bianconi, Jan Hackel, Maria Vorontsova, Adriana Alberti, Watchara Arthan, Sean Burke, Melvin Duvall, Elizabeth Kellogg, Sébastien Lavergne, Michael McKain, Alexandre Meunier, Colin Osborne, Paweena Traiperm, Pascal-Antoine Christin & Guillaume Besnard
C4 photosynthesis is a complex trait that sustains fast growth and high productivity in tropical and subtropical conditions and evolved repeatedly in flowering plants. One of the major C4 lineages is Andropogoneae, a group of ~ 1,200 grass species that includes some of the world's most important crops and species dominating tropical and some temperate grasslands. Previous efforts to understand C4 evolution in the group have compared a few model C4 plants to distantly related...

Using proxies of microbial community‐weighted means traits to explain the cascading effect of management intensity, soil and plant traits on ecosystem resilience in mountain grasslands

Gabin Piton, Nicolas Legay, Cindy Arnoldi, Sandra Lavorel, Jean-Christophe Clément, Arnaud Foulquier & Jean Christophe Clément
1. Trait-based approaches provide a framework to understand the role of functional biodiversity on ecosystem functioning under global change. While plant traits have been reported as potential drivers of soil microbial community composition and resilience, studies directly assessing microbial traits are scarce, limiting our mechanistic understanding of ecosystem functioning. 2. We used microbial biomass and enzyme stoichiometry, and mass-specific enzymes activity as proxies of microbial community-weighted mean (CWM) traits, to infer trade-offs in microbial strategies...

Data from: High-throughput microsatellite genotyping in ecology: improved accuracy, efficiency, standardization and success with low-quantity and degraded DNA

Marta De Barba, Christian Miquel, Stephane Lobreaux, Pierre Yves Quenette, Jon E. Swenson & Pierre Taberlet
Microsatellite markers have played a major role in ecological, evolutionary and conservation research during the past 20 years. However, technical constrains related to the use of capillary electrophoresis and a recent technological revolution that has impacted other marker types have brought to question the continued use of microsatellites for certain applications. We present a study for improving microsatellite genotyping in ecology using high-throughput sequencing (HTS). This approach entails selection of short markers suitable for HTS,...

Data from: On-demand sildenafil as a treatment for Raynaud phenomenon: a series of n-of-1 trials

Matthieu Roustit, Joris Giai, Olivier Gaget, Charles Khouri, Myriam Mouhib, Adrien Lotito, Sophie Blaise, Christophe Seinturier, Fabien Subtil, Adeline Paris, Claire Cracowski, Bernard Imbert, Patrick Carpentier, Sunita Vohra & Jean-Luc Cracowski
Background: Treatment of Raynaud phenomenon (RP) with phosphodiesterase-5 inhibitors has shown moderate efficacy. Adverse effects decrease the risk–benefit profile of these drugs, and patients may not be willing to receive long-term treatment. On-demand single doses before or during exposure to cold may be a good alternative. Objective: To assess the efficacy and safety of on-demand sildenafil in RP. Design: Series of randomized, double-blind, n-of-1 trials. (ClinicalTrials.gov: NCT02050360). Setting: Outpatients at a French university hospital. Participants:...

Data from: pcadapt: an R package to perform genome scans for selection based on principal component analysis

Keurcien Luu, Eric Bazin & Michael G. B. Blum
The R package pcadapt performs genome scans to detect genes under selection based on population genomic data. It assumes that candidate markers are outliers with respect to how they are related to population structure. Because population structure is ascertained with principal component analysis, the package is fast and works with large-scale data. It can handle missing data and pooled sequencing data. By contrast to population-based approaches, the package handle admixed individuals and does not require...

Simulation of sheared granular layers activated by fluid pressurization

Nho Gia Hien Nguyen, Luc Scholtès, Yves Guglielmi, Frédéric Victor Donzé, Zady Ouraga & Mountaka Souley
Fluid pressurization of critically stressed sheared zones can trigger slip mechanisms at play in many geological rupture processes, including earthquakes or landslides. The increasing fluid pressure reduces the effective stress, giving possibility to the shear zone to reactivate. Nonetheless, the mechanisms that dictate the mode of slip, from aseismic steady creep to seismic dynamic rupture, remain poorly understood. By using discrete element modeling, we simulate pore-pressure-step creep test experiments on a sheared granular layer under...

The generality of cryptic dietary niche differences in diverse large-herbivore assemblages

Robert Pringle, Johan Pansu, Matthew Hutchinson, T. Michael Anderson, Mariska Te Beest, Colleen Begg, Keith Begg, Aurelie Bonin, Lackson Chama, Simon Chamaillé-Jammes, Eric Coissac, Joris Cromsigt, Margaret Demmel, Jason Donaldson, Jennifer Guyton, Christina Hansen, Christopher Imakando, Azwad Iqbal, Davis Kalima, Graham Kerley, Samson Kurukura, Marietjie Landman, Ryan Long, Isaack Munuo, Ciara Nutter … & Tyler Kartzinel
Ecological niche differences are necessary for stable species coexistence but are often difficult to discern. Models of dietary niche differentiation in large mammalian herbivores invoke the quality, quantity, and spatiotemporal distribution of plant tissues and growth-forms but are agnostic towards food-plant species identity. Empirical support for these models is variable, suggesting that additional mechanisms of resource partitioning may be important in sustaining large-herbivore diversity in African savannas. We used DNA metabarcoding to conduct a taxonomically...

Environmental and biotic drivers of soil microbial β‐diversity across spatial and phylogenetic scales

Loïc Chalmandrier, Johan Pansu, Lucie Zinger, Frederic Boyer, Eric Coissac, Alexandre Génin, Ludovic Gielly, Sébastien Lavergne, Nicolas Legay, Vincent Schilling, Pierre Taberlet, Tamara Münkemüller & Wilfried Thuiller
Soil microbial communities play a key role in ecosystem functioning but still little is known about the processes that determine their turnover (β-diversity) along ecological gradients. Here, we characterize soil microbial β-diversity at two spatial scales and at multiple phylogenetic grains to ask how archaeal, bacterial and fungal communities are shaped by abiotic processes and biotic interactions with plants. We characterized microbial and plant communities using DNA metabarcoding of soil samples distributed across and within...

Data from: Mapping the imprint of biotic interactions on β-diversity

Marc Ohlmann, Florent Mazel, Loïc Chalmandrier, Stéphane Bec, Eric Coissac, Ludovic Gielly, Johan Pansu, Vincent Schilling, Pierre Taberlet, Lucie Zinger, Jerome Chave & Wilfried Thuiller
Investigating how trophic interactions influence the β-diversity of meta-communities is of paramount importance to understanding the processes shaping biodiversity distribution. Here, we apply a statistical method for inferring the strength of spatial dependencies between pairs of species groups. Using simulated community data generated from a multi-trophic model, we showed that this method can approximate biotic interactions in multi-trophic communities based on β-diversity patterns across groups. When applied to soil multi-trophic communities along an elevational gradient...

Annual Ice Velocity of the Greenland Ice Sheet (1972-1990)

Jeremie Mouginot, Eric Rignot, Romain Millan, Michael Wood & Bernd Scheuchl
We derive surface ice velocity using data from 16 satellite sensors deployed by 6 different space agencies. The list of sensors and the year that they were used are listed in the following (Table S1). The SAR data are processed from raw to single look complex using the GAMMA processor (www.gamma-rs.ch). All measurements rely on consecutive images where the ice displacement is estimated from tracking or interferometry (Joughin et al. 1998, Michel and Rignot 1999,...
