Maternal and fetal blood pharmacokinetics and organ distribution of atrazine, propazine, simazine and their metabolites in pregnant rats after chronic oral administration

Pascal Le Corre, Nolwenn Brandhonneur, Vincent Hutin, Cecile Chevrier & Sylvaine Cordier
Environmental contamination by chlorotriazines has been evidenced in mother-child cohort suggesting more detailed risk assessment of these compounds in drinking water. Exposure of rodents to atrazine has been associated to alterations of endocrine and reproductive functions by disrupting neuroendocrine control at hypothalamus level. Perinatal exposure to low doses of atrazine has been associated to reproductive dysfunction, and to behavioral abnormalities in adult exposed during embryogenesis. The objectives of the current investigation were to (1) evaluate...

Exploring the genetic consequences of clonality in haplodiplontic taxa

Stacy Krueger-Hadfield, Marie-Laure Guillemin, Christophe Destombe, Myriam Valero & Solenn Stoeckel
Partially clonality is an incredibly common reproductive mode found across all the major eukaryotic lineages. Yet, population genetic theory is based on exclusive sexuality or exclusive asexuality and partial clonality is often ignored. This is particularly true in haplodiplontic eukaryotes, including algae, ferns, mosses, and fungi, where somatic development occurs in both the haploid and diploid stages. Haplodiplontic life cycles are predicted to be correlated with asexuality, but tests of this prediction are rare. Moreover,...

Survival and growth of Symphonia seedlings in a reciprocal transplantation experiment

Niklas Tysklind, Marie-Pierre Etienne, Ivan Scotti, Caroline Scotii-Saintagne, Alexandra Tinaut, Maxime Casalis, Valerie Troispoux, Saint Omer Cazal & Louise Brousseau
Trees are characterised by the large number of seeds they produce. Although most of those seeds will never germinate, plenty will. Of those which germinate, many die young, and eventually only a minute fraction will grow to adult stage and reproduce. Is this just a random process? Do variations in germination and survival at very young stages rely on variations in adaptations to microgeographic heterogeneity? and do these processes matter at all in determining tree...

Least‐cost path analysis for urban greenways planning: a test with moths and birds across two habitats and two cities

Manon Balbi, Solène Croci, Eric J. Petit, Alain Butet, Romain Georges, Luc Madec, Jean-Pierre Caudal & Aude Ernoult
1. One of the major planning tools to respond to urban landscape fragmentation is the development of ecological corridors, i.e. interconnected networks of urban green and blue spaces. Least-cost paths (LCP) appear to be an easy and appropriate resistance-based modeling method to respond to urban planners’ needs. However, the ecological validation of urban corridors using LCP is rarely performed and needs to be generalized to different species, habitats and cities. 2. We developed an experimental...

AQMO_SV

François Bodin
The sensor values (AQMO_SV) encompass the following data fields: - PM10 value - PM2.5 value - PM1 value (optional) - Timestamp - Sensor identification - Localisation of the measurement (GPS coordinate) - Temperature in Celsius degrees (optional) - Percentage of humidity (optional) These data are collected by mobile sensors set up on bus bodies. The data acquisition is performed every 10 seconds. One high quality sensor will be installed for calibrating the mobile one. This...

Acoustic data in four species of macaques

Nancy Rebout, Bernard Thierry, Alban Lemasson, Micheletta Jérôme & Roberto Cozzolino
We provide comparative data on vocal signals in adult females of four species of macaque : Tonkean macaques (Macaca tonkeana), crested macaques (M. nigra), Japanese macaques (M. fuscata), and rhesus macaques (M. mulatta). We distinguished three social contexts: agonistic, affiliative and neutral. The agonistic context included aggression (supplantation, lunge, chase, slap, grab, bite, facial threat display) and response to aggression (aggression, avoidance, flight, crouch, submissive facial displays). The affiliative context included affiliative behaviours (approach, sitting...

SynPaFlex-Corpus

Damien Lolive & Aghilas Sini
This resource is an expressive French audiobooks corpus containing eighty seven hours of good audio quality speech, recorded by a single amateur speaker reading audiobooks of different literary genres. This corpus departs from existing corpora collected from audiobooks since they usually provide a few hours of mono-genre and multi-speaker speech. The motivation for setting up such a corpus is to explore expressiveness from different perspectives, such as discourse styles, prosody, and pronunciation, and using different...

Evolution of putative barrier loci at an intermediate stage of speciation with gene flow in campions (Silene)

Xiaodong Liu, Xiaodong Liu, Sylvain Glemin & Sophie Karrenberg
Understanding the origin of new species is a central goal in evolutionary biology. Diverging lineages often evolve highly heterogeneous patterns of genetic differentiation; however, the underlying mechanisms are not well understood. We investigated evolutionary processes governing genetic differentiation between the hybridizing campions Silene dioica (L.) Clairv. and S. latifolia Poiret. Demographic modeling indicated that the two species diverged with gene flow. The best-supported scenario with heterogeneity in both migration rate and effective population size suggested...

Data from: Shells of the bivalve Astarte moerchi give new evidence of a strong pelagic-benthic coupling shift occurring since the late 1970s in the NOW Polynya

Frederic Olivier, Blandine Gaillard, Julien Thébault, Tarik Meziane, Réjean Tremblay, Dany Dumont, Simon Bélanger, Michel Gosselin, Aurélie Jolivet, Laurent Chauvaud, André L. Martel, Søren Rysgaard, Anne-Hélène Olivier, Julien Pettré, Jérôme Mars, Silvain Gerber & Philippe Archambault
Climate changes in the Arctic may weaken the currently tight pelagic-benthic coupling. In response to decreasing sea ice cover, arctic marine systems are expected to shift from a ‘sea-ice algae-benthos’ to a ‘phytoplankton-zooplankton’ dominance. We used mollusk shells as bioarchives and fatty acid trophic markers to estimate the effects of the reduction of sea ice cover on the exported food to the seafloor. Bathyal bivalve Astarte moerchi that lives at 600 m depth in northern...
