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

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,...

Support for the climatic variability hypothesis depends on the type of thermal plasticity: lessons from predation rates

Ying-Jie Wang, Robby Stoks, Arnaud Sentis & Nedim Tüzün
Plastic and evolutionary changes in traits related to biotic interactions are crucial for the local persistence of populations under global warming. Yet, how acute and developmental thermal plasticity evolve and shape predation rates has been poorly studied, especially in the context of latitude-driven thermal evolution. A powerful predictive framework is given by the climatic variability hypothesis (CVH) stating that thermal plasticity and acclimation capacity evolve to be higher in high-latitude populations because these are exposed...

Data from: Variability of the atmospheric PM10 microbiome in three climatic regions of France

Air pollution is a major public-health concern and it is recognized that particulate matter causes damage to human health through oxidative-stress, being responsible for several million premature deaths worldwide each year. Recent findings showed that, airborne microorganisms/spores can modulate aerosol toxicity by altering the oxidative potential of PM10. Primary Biogenic Organic Aerosols (PBOA) appears to be produced by only few genera of microorganisms, emitted by surrounding vegetation in the case of a regionally-homogeneous field site....

Data from: Plotting for change: an analytic framework to aid decisions on which lineages are candidate species in phylogenomic species discovery

Arthur Georges, Peter Unmack, Mark Adams, Michael Hammer, Jerald Johnson, Bernd Gruber, André Gilles & Matthew Young
A recent study argued that coalescent-based models of species delimitation mostly delineate population structure not species, and called for the validation of candidate species using biological information additional to the genetic information, such as phenotypic or ecological data. Here we introduce a framework to interrogate genomic datasets and coalescent-based species trees for the presence of candidate species in situations where additional biological data are unavailable, unobtainable, or uninformative. For de novo genomic studies of species...

Cold adaptation across the elevation gradient in an alpine butterfly species complex

Gabriel Nève & Laurence Després
1. Temperature acts as a major factor on the timing of activity and behaviour in butterflies, and it might represent a key driver of butterfly diversification along elevation gradients. Under this hypothesis, local adaptation should be found along the elevation gradient, with butterflies from high elevation populations able to remain active at lower ambient temperature than those from low elevation. 2. We recorded the warming-up rate and the thoracic temperature at take-off of 123 individuals...

Innate immunity promotes sleep through epidermal antimicrobial peptides

Marina Patricia Sinner, Florentin Masurat, Jonathan Ewbank, Nathalie Pujol & Henrik Bringmann
Wounding and infection trigger a protective innate immune response that includes the production of antimicrobial peptides in the affected tissue as well as increased sleep. Little is known, however, how peripheral wounds or innate immunity signal to the nervous system to increase sleep. We found that during C. elegans larval molting, an epidermal tolloid/BMP-1-like protein called NAS-38 promotes sleep. NAS-38 is negatively regulated by its thrombospondin domain and acts through its astacin protease domain to...

Endometrioma ethanol sclerotherapy could increase IVF live birth rate in women with moderate-severe endometriosis

Laura Miquel, Lise Preaubert, Audrey Gnisci, Noemie Resseguier, Audrey Pivano, Jeanne Perrin & Blandine Courbiere
Objective: To examine the impact of ethanol sclerotherapy (EST) for endometrioma on in vitro fertilization (IVF) cumulative live birth rates (CLBR) in women with moderate-severe endometriosis. Methods: This retrospective cohort study included women with moderate-severe endometriosis (revised American Fertility Society stage III-IV) and endometrioma who underwent IVF with the ultra-long agonist protocol. We compared two groups: women undergoing EST for endometrioma before IVF (EST group), and women whose endometrioma was left in situ during IVF...

Data from: Influence of intra- and interspecific variation in predator-prey body size ratios on trophic interaction strengths

Ross N. Cuthbert, Ryan J. Wasserman, Tatenda Dalu, Horst Kaiser, Olaf L. F. Weyl, Jaimie T. A. Dick, Arnaud Sentis, Mike W. McCoy & Mhairi E. Alexander
1. Predation is a pervasive force that structures food webs and directly influences ecosystem functioning. The relative body sizes of predators and prey may be an important determinant of interaction strengths. However, studies quantifying the combined influence of intra- and interspecific variation in predator-prey body size ratios are lacking. 2. We use a comparative functional response approach to examine interaction strengths between three size classes of invasive bluegill and largemouth bass towards three scaled size...
