Öztürk, Vincent Ridoux, Emer Rogan, Ursula Siebert, Marina Sequeira, Gísli A. Vikingsson, Asunción Borrell, Johan R. Michaux & Alex Aguilar
Despite no obvious barriers to gene flow in the marine realm, environmental variation and ecological specializations can lead to genetic differentiation in highly mobile predators. Here, we investigated the genetic structure of the harbor porpoise over the entire species distribution range in western Palearctic waters. Combined analyses of ten microsatellite loci and a 5,085 bases-pairs portion of the mitochondrial genome revealed the existence of three ecotypes, equally divergent at the mitochondrial genome, distributed in the...

Data from: Partitioning the relative contribution of one-phase and two-phase seed dispersal when evaluating seed dispersal effectiveness

Laurence Culot, Marie-Claude Huynen & Eckhard W. Heymann
Seed dispersal effectiveness (SDE) is a conceptual framework that aims at quantifying the contribution of seed dispersal vectors to plant fitness. While it is well recognized that diplochorous dispersal systems, characterized by two successive dispersal steps performed by two different vectors (Phase I = primary seed dispersal and Phase II = secondary seed dispersal) are common in temperate and tropical regions, little attention has been given to distinguishing the relative contribution of one-phase and two-phase...

Data from: How bees deter elephants: beehive trials with forest elephants (Loxodonta africana cyclotis) in Gabon

Steeve Ngama, Lisa Korte, Jérôme Bindelle, Cédric Vermeulen & John R. Poulsen
In Gabon, like elsewhere in Africa, crops are often sources of conflict between humans and wildlife. Wildlife damage to crops can drastically reduce income, amplifying poverty and creating a negative perception of wild animal conservation among rural people. In this context, crop-raiding animals like elephants quickly become “problem animals”. To deter elephants from raiding crops beehives have been successfully employed in East Africa; however, this method has not yet been tested in Central Africa. We...

Volatiles of bacteria associated with parasitoid habitats elicit distinct olfactory responses in an aphid parasitoid and its hyperparasitoid

Tim Goelen, Islam S. Sobhy, Christophe Vanderaa, Jetske G. De Boer, Frank Delvigne, Frédéric Francis, Felix Wäckers, Hans Rediers, Kevin J. Verstrepen, Tom Wenseleers, Hans Jacquemyn & Bart Lievens
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...

Genomic footprints of recovery in the European bison

Tom Druet, Kamil Oleński, Laurence Flori, Amandine Bertrand, Wanda Olech, Malgorzata Tokarska, Stanislaw Kaminski & Mathieu Gautier
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...

Data from: Dealing with paralogy in RADseq data: in silico detection and single nucleotide polymorphism validation in Robinia pseudoacacia L.

Cindy F. Verdu, Erwan Guichoux, Samuel Quevauvillers, Olivier De Thier, Yec'han Laizet, Adline Delcamp, Frédéric Gévaudant, Arnaud Monty, Annabel J. Porté, Philippe Lejeune, Ludivine Lassois & Stéphanie Mariette
The RADseq technology allows researchers to efficiently develop thousands of polymorphic loci across multiple individuals with little or no prior information on the genome. However, many questions remain about the biases inherent to this technology. Notably, sequence misalignments arising from paralogy may affect the development of single nucleotide polymorphism (SNP) markers and the estimation of genetic diversity. We evaluated the impact of putative paralog loci on genetic diversity estimation during the development of SNPs from...

Data from: From animal tracks to fine-scale movement modes: a straightforward approach for identifying multiple, spatial movement patterns

Kevin Morelle, Nils Bunnefeld, Philippe Lejeune & Steve A. Oswald
1. Thanks to developments in animal tracking technology, detailed data on the movement tracks of individual animals are now attainable for many species. However, straightforward methods to decompose individual tracks into high-resolution, spatial modes are lacking but are essential to understand what an animal is doing. 2. We developed an analytical approach that combines separately-validated methods into a straightforward tool for converting animal GPS tracks to short-range movement modes. Our three-step analytical process comprises: (1)...

Data from: The size at reproduction of canopy tree species in central Africa

Dakis-Yaoba Ouédraogo, Jean-Louis Doucet, Kasso Daïnou, Fidèle Baya, Achille Bernard Biwolé, Nils Bourland, Fousséni Fétéké, Jean-François Gillet, Yao Lambert Kouadio & Adeline Fayolle
Size at reproduction is a key aspect of species life history that has been little explored for long-lived tropical trees. In this study, we aimed to quantify reproductive diameter for 31 major timber species across 11 sites in Cameroon, Congo, and Central African Republic. Specifically, we examined (1) whether between-species variability can be explained by a set of seven species traits; (2) whether reproductive diameter varied within-species among sites; (3) whether reproductive status varied with...

Data from: Minimally invasive estimation of ventricular dead space volume through use of Frank-Starling curves

Shaun Davidson, Chris Pretty, Antoine Pironet, Thomas Desaive, Nathalie Janssen, Bernard Lambermont, Philippe Morimont & J. Geoffrey Chase
This paper develops a means of more easily and less invasively estimating ventricular dead space volume (Vd), an important, but difficult to measure physiological parameter. Vd represents a subject and condition dependent portion of measured ventricular volume that is not actively participating in ventricular function. It is employed in models based on the time varying elastance concept, which see widespread use in haemodynamic studies, and may have direct diagnostic use. The proposed method involves linear...

Data from: Toward a standardised protocol for the stable isotope analysis of scleractinian corals

Nicolas Sturaro, Yunli Eric Hsieh, Qi Chen, Pei-Ling Wang & Vianney Denis
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...

Data from: Similar levels of trophic and functional diversity within damselfish assemblages across Indo–Pacific coral reefs

Laura Gajdzik, Eric Parmentier, Loïc N. Michel, Nicolas Sturaro, Keryea Soong, Gilles Lepoint & Bruno Frédérich
1. Understanding the forces that influence the dynamics of communities is a key challenge to undertake in changing environments. Despite recent advances in coral reef community ecology, a more comprehensive knowledge about processes (niche related–traits and phylogenies) driving the composition of reef fish community is needed. 2. Here, we conducted a quantitative comparison of these processes in damselfish assemblages that belong to three distinct Indo–Pacific coral reefs differing in taxonomic composition, morphology and degree of...

Unprecedented biting performance in herbivorous fish: how the complex biting system of Pomacentridae circumvents performance trade-offs

Damien 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...

Data from: Timing of perineuronal nets development in the zebra finch song control system correlates with developmental song learning

Gilles Cornez, Elisabeth Jonckers, Sita M. Ter Haar, Annemie Van Der Linden, Charlotte A. Cornil & Jacques Balthazart
The appearance of perineuronal nets (PNN) represents one of the mechanisms that contribute to the closing of sensitive periods for neural plasticity. This relationship has mostly been studied in the ocular dominance model in rodents. Previous studies also indicated that PNN might control neural plasticity in the song control system (SCS) of songbirds. To further elucidate this relationship, we quantified PNN expression and their localization around parvalbumin interneurons at key time-points during ontogeny in both...

Data from: Understanding the recruitment response of juvenile Neotropical trees to logging intensity using functional traits

J. Aaron Hogan, Bruno Hérault, Bénédicte Bachelot, Anaїs Gorel, Marianne Jounieaux & Christopher Baraloto
Selective-logging remains a widespread practice in tropical forests, yet the long-term effects of timber-harvest on juvenile tree (i.e., sapling) recruitment across the hundreds of species occurring in most tropical forests, remain difficult to predict. This uncertainty could potentially exacerbate threats to some of the thousands of timber-valuable tree species in the Amazon. Our objective was to determine to what extent long-term responses of tree species regeneration in logged forests can be explained by their functional...

Data from: Biotic predictors complement models of bat and bird responses to climate and tree diversity in European forests

Luc Barbaro, Eric Allan, Evy Ampoorter, Bastien Castagneyrol, Yohan Charbonnier, Hans De Wandeler, Christian Kerbiriou, Harriet Milligan, Aude Vialatte, Monique Carnol, Marc Deconchat, Pallieter De Smedt, Herve Jactel, Julia Koricheva, Isabelle Le Viol, Bart Muys, Michael Scherer-Lorenzen, Kris Verheyen & Fons Van Der Plas
Bats and birds are key providers of ecosystem services in forests. How climate and habitat jointly shape their communities is well studied, but whether biotic predictors from other trophic levels may improve bird and bat diversity models is less known, especially across large bioclimatic gradients. Here, we achieved multi-taxa surveys in 209 mature forests replicated in six European countries from Spain to Finland, to investigate the importance of biotic predictors (i.e., the abundance or activity...

Validation of a French-language version of TeamSTEPPS® T-TPQ and T-TAQ questionnaires

Anh Nguyet Diep, Méryl Paquay, Jean-Christophe Servotte, Nadia Dardenne, Laure Istas, Pauline Van Ngoc, Mathilde Charlier, Alexandre Ghuysen & Anne-Françoise Donneau
Teamwork training and evaluation are essential to enhance safety and quality of care. The lack of the psychometric testing of the TeamSTEPPS® Teamwork Attitudes Questionnaire (T-TAQ) and Teamwork Perceptions Questionnaire (T-TPQ) across different language and cultural settings has questioned their widespread use because such attitudes and perceptions are highly subjective and context-bound. The present study aims to translate the T-TAQ and T-TPQ into the French language and validate the psychometric properties of the two questionnaires...

How culture breaks down the mind-body divide. An interview with Maddalena Canna and Rebecca Seligman by Matthieu Koroma

Canna Maddalena, Rebecca Seligman & Matthieu Koroma
In this interview, anthropologists Maddalena Canna and Rebecca Seligman explain their recent research agenda investigating how culture shapes the relationship between the body and mind. After having studied trance, they shift their focus to Functional Neurological Disorder (FND), an illness in which sensory or motor symptoms do not match any identified physiological causes. Their approach relies on a mix of anthropological and psychophysiological methods to unravel the mechanisms by which cultural expectations influence the perception...

Data from: Periodic environmental disturbance drives repeated ecomorphological diversification in an adaptive radiation of Antarctic fishes

Elyse Parker, Katerina L. Zapfe, Jagriti Yadav, Bruno Frédérich, Christopher D. Jones, Evan P. Economo, Sarah Federman, Thomas J. Near & Alex Dornburg
The ecological theory of adaptive radiation has profoundly shaped our conceptualization of the rules that govern diversification. However, while many radiations follow classic early burst patterns of diversification as they fill ecological space, the longer-term fates of these radiations depend on many factors, such as climatic stability. In systems with periodic disturbances, species-rich clades can contain nested adaptive radiations of subclades with their own distinct diversification histories, and how adaptive radiation theory applies in these...

Termite dispersal is influenced by their diet

Simon Hellemans, Jan Šobotník, Gilles Lepoint, Martin Mihaljevič, Yves Roisin & Thomas Bourguignon
Termites feed on vegetal matter at various stages of decomposition. Lineages of wood- and soil-feeding termites are distributed across terrestrial ecosystems located between 45°N and 45°S of latitude, a distribution they acquired through many transoceanic dispersal events. While wood-feeding termites often live in the wood on which they feed and are efficient at dispersing across oceans by rafting, soil-feeders are believed to be poor dispersers. Therefore, their distribution across multiple continents requires an explanation. Here,...

Data from: Climatic niche lability but growth form conservatism in the African woody flora

Anaïs-Pasiphaé Gorel, Olivier J. Hardy, Gilles Dauby, Kyle G. Dexter, Ricardo A. Segovia, Kathy Steppe & Adeline Fayolle
Climatic niche evolution during the diversification of tropical plants has received little attention in Africa. To address this, we characterized the climatic niche of >4000 tropical African woody species, distinguishing two broad bioclimatic groups (forest vs. savanna) and six subgroups. We quantified niche conservatism versus lability at the genus level and for higher clades, using a molecular phylogeny of >800 genera. Although niche stasis at speciation is prevalent, numerous clades individually cover vast climatic spaces...
