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...

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,...

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...

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...

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....

Dix ans après la départementalisation de Mayotte, le cadre juridique du financement de la collectivité n’est toujours pas stabilisé. La persistance de régimes transitoires et dérogatoires, avec, notamment, le maintien des impositions locales, s’ajoute aux difficultés d’application de la fiscalité directe locale de droit commun, en vigueur depuis le 1er janvier 2014. Or l’accession de Mayotte au statut de région ultrapériphérique de l’Union européenne se conjugue mal avec le maintien de ces impositions dérogatoires, comme...

Data for Whiting et al. (2020, Cognition): "The perception of caricatured emotion in voice". Raw behavioural data and sound stimuli.

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...

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...
