The use of psychedelics in the treatment of disorders of consciousness. An interview with Olivia Gosseries by Charlotte Martial.Olivia Gosseries & Charlotte Martial
In this interview, we discuss the use of psychedelic drugs as a promising treatment in disorders of consciousness. Psilocybin, a classic psychedelic, is currently undergoing substantial clinical investigations in healthy volunteers, but also in clinical populations. Recently, experts in the field of psychedelics have addressed the attractive possibility to use such psychedelics on patients suffering from disorders of consciousness. Building on her empirical and theoretical research on disorders of consciousness, Olivia Gosseries gives us her...

Data from: Multiple glacial refugia and contemporary dispersal shape the genetic structure of an endemic amphibian from the PyreneesFederica Lucati, Manon Poignet, Alexandre Miró, Audrey Trochet, Fabien Aubret, Laurent Barthe, Romain Bertrand, Teresa Buchaca, Olivier Calvez, Jenny Caner, Elodie Darnet, Mathieu Denoël, Olivier Guillaume, Hugo Le Chevalier, Albert Martínez-Silvestre, Marc Mossoll-Torres, David O’Brien, Víctor Osorio, Gilles Pottier, Murielle Richard, Ibor Sabás, Jérémie Souchet, Jan Tomàs & Marc Ventura
Historical factors (colonization scenarios, demographic oscillations) and contemporary processes (population connectivity, current population size) largely contribute to shaping species’ present-day genetic diversity and structure. In this study, we use a combination of mitochondrial and nuclear DNA markers to understand the role of Quaternary climatic oscillations and present-day gene flow dynamics in determining the genetic diversity and structure of the newt Calotriton asper (Al. Dugès, 1852), endemic to the Pyrenees. Mitochondrial DNA did not show a...
Unprecedented biting performance in herbivorous fish: how the complex biting system of Pomacentridae circumvents performance trade-offsDamien Olivier, Sam Van Wassenbergh, Eric Parmentier & Bruno Frédérich
It is well accepted that the complexity of functional systems may mitigate performance trade-offs. However, data supporting this theory is hard to find because it needs to be based on a functional system with different complexity levels in closely-related species. The Pomacentridae (damselfishes) provide an excellent opportunity to test the hypothesis because most of the species have two mouth-closing systems: the first using the adductor mandibulae, as in all teleost fishes, and a second one...
Volatiles of bacteria associated with parasitoid habitats elicit distinct olfactory responses in an aphid parasitoid and its hyperparasitoidTim Goelen, Islam S. Sobhy, Christophe Vanderaa, Jetske G.

1. To locate mating partners and essential resources such as food, oviposition sites and shelter, insects rely to a large extent on chemical cues. While most research has focused on cues derived from plants and insects, there is mounting evidence that indicates that microorganisms emit volatile compounds that may play an important role in insect behaviour. 2. In this study, we assessed how volatile compounds emitted by phylogenetically diverse bacteria affected the olfactory response of...
After extinction in the wild in the beginning of the twentieth century, the European bison has been successfully recovered in two distinct genetic lines from only twelve and seven captive founders. We here aimed at characterizing the levels of realized inbreeding in these two restored lines to provide empirical insights into the genomic footprints left by population recovery from a small number of founders. To that end, we genotyped 183 European bison born over the...
Rationale: The stable isotope analysis of carbon and nitrogen is a powerful tool in many ecological studies, but different sample treatments may affect stable isotope ratios and hamper comparisons among studies. The goal of this study was to determine whether treatments that are commonly used to prepare scleractinian coral samples for stable isotope analysis yield different δ15N and δ13C values, and to provide guidelines toward a standardised protocol. Methods: The animal tissues and Symbiodiniaceae of...
Parasitic wasps use specialized needle-like structures—ovipositors—to drill in substrates to reach hidden hosts. The external ovipositor (terebra) consists of three interconnected, sliding elements (valvulae) which are moved reciprocally during insertion. This presumably reduces the required pushing force on the terebra and limits the risk of damage whilst probing. Although this is an important mechanism, it is still not completely understood how the actuation of the valvulae is achieved, and it has only been studied with...
Meiotic recombination is an essential biological process that ensures proper chromosome segregation and creates genetic diversity. Individual variation in global recombination rates has been shown to be heritable in several species and variants significantly associated with this trait have been identified. Recombination on the sex chromosome has often been ignored in these studies although this trait may be particularly interesting as it may correspond to a biological process distinct from that on autosomes. For instance,...
Phosphorene is a new 2D material that has recently attracted much attention owing to its fascinating electrical, optical, thermal, and chemical properties. Here, we report on high-quality exfoliation of black phosphorus nanosheets, with controllable size produced in large quantities by liquid phase exfoliation using N-methyl-2-pyrrolidone (NMP) as a solvent under ambient conditions. The as-synthesized few layers show a great potential for solar energy conversion based on the optical results shown in this work.
First use of acoustic calls to distinguish cryptic fish species: Dascyllus aruanus complex as a case studyEric Parmentier, Eric Parmentier, Robin Scalbert, Xavier Raick, Camille Gache, Bruno Frédérich, Frederic Bertucci & David Lecchini
From a practical point of view, the determination of species in the wild is based on their phenotypes. Consequently, many species remain unknown because they are visually indistinguishable from described species. Although molecular methods and advances in bioacoustical analysis have been extensively used to uncover cryptic species, the combination of both methodologies is still rare and concerns only some terrestrial taxa such as insects, bats, frogs and birds. In this study, we aim to determine...
Data from: A new Devonian euthycarcinoid evidences the use of different respiratory strategies during the marine-to-terrestrial transition in the myriapod lineagePierre Gueriau, James C. Lamsdell, Roy A. Wogelius, Phillip L. Manning, Victoria M. Egerton, Uwe Bergmann, Loïc Bertrand & Julien Denayer
Myriapods were, together with arachnids, the earliest animals to occupy terrestrial ecosystems, by at least the Silurian. The origin of myriapods and their land colonization have long remained puzzling until euthycarcinoids, an extinct group of aquatic arthropods considered amphibious, were shown to be stem group myriapods, extending the lineage to the Cambrian and evidencing a marine-to-terrestrial transition. Although possible respiratory structures comparable to the air-breathing tracheal system of myriapods are visible in several euthycarcinoids, little...
The estimation of the inbreeding coefficient (F) is essential for the study of inbreeding depression (ID) or for the management of populations under conservation. Several methods have been proposed to estimate the realized F using genetic markers, but it remains unclear which one should be used. Here we used whole-genome sequence data for 245 individuals from a Holstein cattle pedigree to empirically evaluate which estimators best capture homozygosity at variants causing ID, such as rare...
