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: Postglacial climate changes and rise of three ecotypes of harbor porpoises, Phocoena phocoena, in western Palearctic waters

Michaël C. Fontaine, Kathleen Roland, Isabelle Calves, Frederic Austerlitz, Friso P. Palstra, Krystal A. Tolley, Sean Ryan, Marisa Ferreira, Thierry Jauniaux, Angela Llavona, Bayram Öztürk, Ayaka A. 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: 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...

Supplementary Information for Biogeography a key influence on distal forelimb variation in horses through the Cenozoic

Jamie MacLaren
Locomotion in terrestrial tetrapods is reliant on interactions between distal limb bones (e.g. metapodials and phalanges). The metapodial-phalangeal joint in horse (Equidae) limbs is highly specialised, facilitating vital functions (shock absorption; elastic recoil). While joint shape has changed throughout horse evolution, potential drivers of these modifications have not been quantitatively assessed. Here, I examine the morphology of the forelimb metacarpophalangeal (MCP) joint of horses and their extinct kin (palaeotheres) using geometric morphometrics and disparity analyses,...

Data from: A genome-wide data assessment of the African lion (Panthera leo) population genetic structure and diversity in Tanzania

Nathalie Smitz, Olivia Jouvenet, Fredrick Ambwene Ligate, William-George Crosmary, Dennis Ikanda, Philippe Chardonnet, Alessandro Fusari, Kenny Meganck, François Gillet, Mario Melletti & Johan R. Michaux
The African lion (Panthera leo), listed as a vulnerable species on the IUCN Red List of Threatened Species (Appendix II of CITES), is mainly impacted by indiscriminate killing and prey base depletion. Additionally, habitat loss by land degradation and conversion has led to the isolation of some subpopulations, potentially decreasing gene flow and increasing inbreeding depression risks. Genetic drift resulting from weakened connectivity between strongholds can affect the genetic health of the species. In the...

Data from: Non-reef environments impact the diversification of extant jacks, remoras and allies (Carangoidei, Percomorpha)

Bruno Frederich, Giuseppe Marramà, Giorgio Carnevale & Francesco Santini
Various factors may impact the processes of diversification of a clade. In the marine realm, it has been shown that coral reef environments have promoted diversification in various fish groups. With the exception of requiem sharks, all the groups showing a higher level of diversity in reefs than in non-reef habitats have diets based predominantly on plankton, algae or benthic invertebrates. Here we explore the pattern of diversification of carangoid fishes, a clade that includes...

Data from: The determinants of tropical forest deciduousness: disentangling the effects of rainfall and geology in central Africa

Dakis-Yaoba Ouédraogo, Adeline Fayolle, Sylvie Gourlet-Fleury, Frédéric Mortier, Vincent Freycon, Nicolas Fauvet, Suzanne Rabaud, Guillaume Cornu, Fabrice Bénédet, Jean-François Gillet, Richard Oslisly, Jean-Louis Doucet, Philippe Lejeune & Charly Favier
Understanding the environmental determinants of forests deciduousness i.e. proportion of deciduous trees in a forest stand, is of great importance when predicting the impact of ongoing global climate change on forests. In this study, we examine (i) how forest deciduousness varies in relation to rainfall and geology, and (ii) whether the influence of geology on deciduousness could be related to differences in soil fertility and water content between geological substrates. The study was conducted in...

Data from: Architectural differences associated to functional traits among 45 coexisting tree species in central Africa

Grace Jopaul Loubota Panzou, Gauthier Ligot, Sylvie Gourlet-Fleury, Jean-Louis Doucet, Eric Forni, Jean-Joël Loumeto & Adeline Fayolle
1. Architectural traits that determine the light captured in a given environment are an important aspect of the life-history strategies of tropical tree species. In this study, we examined how interspecific variation in architectural traits is related to the functional traits of 45 coexisting tree species in central Africa. 2. At the tree level, we measured tree diameter, total height and crown dimensions for an average of 30 trees per species (range 14–72, total 968...

Data from: Resolution of the ordinal phylogeny of mosses using targeted exons from organellar and nuclear genomes

Yang Liu, Matthew G. Johnson, Cymon J. Cox, Rafael Medina, Nicolas Devos, Alain Vanderpoorten, Lars Hedenäs, Neil E. Bell, James R. Shevock, Blanka Aguero, Dietmar Quandt, Norman J. Wickett, A. Jonathan Shaw & Bernard Goffinet
Mosses are a highly diverse lineage of land plants, whose diversification, spanning at least 400 million years, remains phylogenetically ambiguous due to the lack of fossils, massive early extinctions, late radiations, limited morphological variation, and conflicting signal among previously used markers. Here, we present phylogenetic reconstructions based on complete organellar exomes and a comparable set of nuclear genes for this major lineage of land plants. Our analysis of 142 species representing 29 of the 30...

Data from: Performance of glomerular filtration rate estimation equations in Congolese healthy adults: inopportunity of ethnic correction

Justine B. Bukabau, Ernest K. Sumaili, Etienne Cavalier, Hans Pottel, Bejos Kifakiou, Aliocha Nkodila, Jean-Robert R Makulo, Vieux M. Mokoli, Chantal V. Zinga, Augustin L. Longo, Yannick M. Engole, Yannick M. Nlandu, François B. Lepira, Nazaire M. Nseka, Jean-Marie Krzesinski, Pierre Delanaye, Jean Robert R. Makulo & Jean Marie Krzesinski
Context and objective: In the estimation of glomerular filtration rate (GFR), ethnicity is an important determinant. However, all existing equations have been built solely from Caucasian and Afro-American populations and they are potentially inaccurate for estimating GFR in African populations. We therefore evaluated the performance of different estimated GFR (eGFR) equations in predicting measured GFR (mGFR). Methods: In a cross-sectional study, 93 healthy adults were randomly selected in the general population of Kinshasa, Democratic Republic...

Data from: Closing a gap in tropical forest biomass estimation: taking crown mass variation into account in pantropical allometries

Pierre Ploton, Nicholas Barbier, Stéphane Takoudjou Momo, Maxime Réjou-Méchain, Faustin Boyemba Bosela, Georges Chuyong, Gilles Dauby, Vincent Droissart, Adeline Fayolle, Rosa Calisto Goodman, Mathieu Henry, Narcisse Guy Kamdem, John Katembo Mukirania, David Kenfack, Moses Libalah, Alfred Ngomanda, Vivien Rossi, Bonaventure Sonké, Nicolas Texier, Duncan Thomas, Donatien Zebaze, Pierre Couteron, Uta Berger & Raphaël Pélissier
Accurately monitoring tropical forest carbon stocks is an outstanding challenge. Allometric models that consider tree diameter, height and wood density as predictors are currently used in most tropical forest carbon studies. In particular, a pantropical biomass model has been widely used for approximately a decade, and its most recent version will certainly constitute a reference in the coming years. However, this reference model shows a systematic bias for the largest trees. Because large trees are...

Data from: GLO-Roots: an imaging platform enabling multidimensional characterization of soil-grown roots systems

Ruben Rellán-Álvarez, Guillaume Lobet, Heike Lindner, Pierre-Luc Pradier, Jose Sebastian, Muh-Ching Yee, Yu Geng, Charlotte Trontin, Therese LaRue, Amanda Schrager-Lavelle, Cara H. Haney, Rita Nieu, Julin Maloof, John P. Vogel & José R. Dinneny
Root systems develop different root types that individually sense cues from their local environment and integrate this information with systemic signals. This complex multi-dimensional amalgam of inputs enables continuous adjustment of root growth rates, direction and metabolic activity that define a dynamic physical network. Current methods for analyzing root biology balance physiological relevance with imaging capability. To bridge this divide, we developed an integrated imaging system called Growth and Luminescence Observatory for Roots (GLO-Roots) that...

Data from: Personality and gonadal development as sources of individual variation in response to GnRH challenge in female great tits

Samuel P. Caro, Charlotte A. Cornil, Kees Van Oers & Marcel E. Visser
Seasonal timing of reproduction is a key life-history trait, but we know little about the mechanisms underlying individual variation in female endocrine profiles associated with reproduction. In birds, 17β-estradiol is a key reproductive hormone that links brain neuroendocrine mechanisms, involved in information processing and decision making, to downstream mechanisms in the liver, where egg-yolk is produced. Here we test, using a simulated induction of the reproductive system through a GnRH-challenge, whether the ovary of pre-breeding...

Data from: Trait decoupling promotes evolutionary diversification of the trophic and acoustic system of damselfishes

Bruno Frédérich, Damien Olivier, Glenn Litsios, Michael E. Alfaro, Eric Parmentier & B. Frederich
Trait decoupling, wherein evolutionary release of constraints permits specialization of formerly integrated structures, represents a major conceptual framework for interpreting patterns of organismal diversity. However, few empirical tests of this hypothesis exist. A central prediction, that the tempo of morphological evolution and ecological diversification should increase following decoupling events, remains inadequately tested. In damselfishes (Pomacentridae), a ceratomandibular ligament links the hyoid bar and lower jaws, coupling two main morphofunctional units directly involved in both feeding...

Data from: Iterative ecological radiation and convergence during the evolutionary history of damselfishes (Pomacentridae)

Bruno Frédérich, Laurie Sorenson, Francesco Santini, Graham J. Slater & Michael E. Alfaro
Coral reef fishes represent one of the most spectacularly diverse assemblages of vertebrates on the planet, but our understanding of their mode of diversification remains limited. Here we test whether the diversity of the damselfishes (Pomacentridae), one of the most species-rich families of reef-associated fishes, was produced by a single or multiple adaptive radiation(s) during their evolutionary history. Tests of the tempo of lineage diversification using a time-calibrated phylogeny including 208 species revealed that crown...

Data from: Maternal nutrition during pregnancy affects testicular and bone development, glucose metabolism and response to overnutrition in weaned horses up to two years

Camille Gautier, Luis Mendoza, Hélène Bouraima-Lelong, Isabelle Guenon, Pauline Peugnet, Cédric Dubois, Sylvaine Camous, Anne Tarrade, Morgane Robles, Didier Serteyn, Isabelle Caudron, Jean-Philippe Lejeune, Laurence Wimel, Michèle Dahirel & Pascale Chavatte-Palmer
Pregnant mares and post-weaning foals are often fed concentrates rich in soluble carbohydrates, together with forage. Recent studies suggest that the use of concentrates is linked to alterations of metabolism and the development of osteochondrosis in foals. The aim of this study was to determine if broodmare diet during gestation affects metabolism, osteoarticular status and growth of yearlings overfed from 20 to 24 months of age and/or sexual maturity in prepubertal colts. Twenty-four saddlebred mares...

Data from: The evolutionary history of polycotylid plesiosaurians

Valentin Fischer, Roger B J Benson, Patrick S Druckenmiller, Hilary F Ketchum & Nathalie Bardet
Polycotylidae is a clade of plesiosaurians that appeared during the Early Cretaceous and became speciose and abundant early in the Late Cretaceous. However, this radiation is poorly understood. Thililua longicollis from the Middle Turonian of Morocco is an enigmatic taxon possessing an atypically long-neck and, as originally reported, a series of unusual cranial features that cause unstable phylogenetic relationships for polycotylids. We reinterpret the holotype specimen of Thililua longicollis and clarify its cranial anatomy. Thililua...

Data from: The shepherds' tale: a genome-wide study across 9 dog breeds implicates two loci in the regulation of fructosamine serum concentration in Belgian shepherds

Simon K. G. Forsberg, Marcin Kierczak, Ingrid Ljungvall, Anne-Christine Merveille, Vassiliki Gouni, Maria Wiberg, Jakob Lundgren Willesen, Sofia Hanås, Anne-Sophie Lequarré, Louise Mejer Sørensen, Laurent Tiret, Kathleen McEntee, Eija Seppälä, Jørgen Koch, Géraldine Battaille, Hannes Lohi, Merete Fredholm, Valerie Chetboul, Jens Häggström, Örjan Carlborg, Kerstin Lindblad-Toh & Katja Höglund
Diabetes mellitus is a serious health problem in both dogs and humans. Certain dog breeds show high prevalence of the disease, whereas other breeds are at low risk. Fructosamine and glycated hemoglobin (HbA1c) are two major biomarkers of glycaemia where serum concentrations reflect glucose turnover over the past few weeks to months. In this study, we searched for genetic factors influencing variation in serum fructosamine concentration in healthy dogs using data from nine dog breeds....

Data from: Teruelia diezii gen. et sp. nov.: an early polysporangiophyte from the Lower Devonian of the Iberian Peninsula

Borja Cascales-Miñana & Philippe Gerrienne
A new basal land plant, Teruelia diezii gen. et sp. nov., is described from the shallow-water marine deposits of the Lower Devonian (Lochkovian–Pragian) Nogueras Formation of the Iberian Peninsula (north Gondwana palaeocontinent). Teruelia is preserved as a compression fossil and consists of isotomously branched, robust stems terminated in large, fusiform, twisted sporangia. This morphology suggests that Teruelia is very probably equivalent to Aglaophyton, a permineralized early polysporangiophyte known up to now only from the Lower...

Data from: Maternal obesity increases insulin resistance, low-grade inflammation and osteochondrosis lesions in foals and yearlings until 18 months of age

Morgane Robles, Emilie Nouveau, Camille Gautier, Luis Mendoza, Cédric Dubois, Michèle Dahirel, Bénédicte Lagofun, Marie-Christine Aubrière, Jean-Philippe Lejeune, Isabelle Caudron, Isabelle Guenon, Catherine Viguié, Laurence Wimel, Hélène Bouraima-Lelong, Didier Serteyn, Anne Couturier-Tarrade, Pascale Chavatte-Palmer, M-C Aubrière & J-P Lejeune
Obesity is a growing concern in horses. The effects of maternal obesity on maternal metabolism and low-grade inflammation during pregnancy, as well as offspring growth, metabolism, low-grade inflammation, testicular maturation and osteochondrotic lesions until 18 months of age were investigated. Twenty-four mares were used and separated into two groups at insemination according to body condition score (BCS): Normal (N, n=10, BCS ≤4) and Obese (O, n=14, BCS ≥4.25). BCS and plasma glucose, insulin, triglyceride, urea,...

Data from: Extensive seed and pollen dispersal and assortative mating in the rain forest tree Entandrophragma cylindricum (Meliaceae) inferred from indirect and direct analyses

Franck Kameni Monthe, Olivier J. Hardy, Jean-Louis Doucet, Judy Loo, Jérôme Duminil & Jean-Louis Doucet
Pollen and seed dispersal are key processes affecting the demographic and evolutionary dynamics of plant species and are also important considerations for the sustainable management of timber trees. Through direct and indirect genetic analyses, we studied the mating system and the extent of pollen and seed dispersal in an economically important timber species, Entandrophragma cylindricum (Meliaceae). We genotyped adult trees, seeds and saplings from a 400-ha study plot in a natural forest from East Cameroon...

Data from: Bayesian analysis of hybridization and introgression between the endangered european mink (Mustela lutreola) and the polecat (Mustela putorius)

Maria Teresa Cabria, Johan R Michaux, Benjamín J Gómez-Moliner, Dimitry Skumatov, Tiit Maran, Pascal Fournier, Javier López De Luzuriaga & Rafael Zardoya
Human-mediated global change will probably increase the rates of natural hybridization and genetic introgression between closely related species, and this will have major implications for conservation of the taxa involved. In this study, we analyse both mitochondrial and nuclear data to characterize ongoing hybridization and genetic introgression between two sympatric sister species of mustelids, the endangered European mink (Mustela lutreola) and the more abundant polecat (M. putorius). A total of 317 European mink, 114 polecats...
