Data from: Accelerometers can measure total and activity-specific energy expenditure in free-ranging marine mammals only if linked to time-activity budgets

Tiphaine Jeanniard-Du-Dot, Christophe Guinet, John P. Y. Arnould, John R. Speakman, Andrew W. Trites & John P.Y. Arnould
Energy expenditure is an important component of foraging ecology, but is extremely difficult to estimate in free-ranging animals and depends on how animals partition their time between different activities during foraging. Acceleration data have emerged as a new way to determine energy expenditure at a fine scale but this needs to be tested and validated in wild animals. This study investigated whether vectorial dynamic body acceleration (VeDBA) could accurately predict the energy expended by marine...

Data from: Does aquatic foraging impact head shape evolution in snakes?

Marion Segall, Raphaël Cornette, Anne-Claire Fabre, Ramiro Godoy-Diana & Anthony Herrel
Evolutionary trajectories are often biased by developmental and historical factors. However, environmental factors can also impose constraints on the evolutionary trajectories of organisms leading to convergence of morphology in similar ecological contexts. The physical properties of water impose strong constraints on aquatic feeding animals by generating pressure waves that can alert prey and potentially push them away from the mouth. These hydrodynamic constraints have resulted in the independent evolution of suction feeding in most groups...

Data from: Immune-challenged fish up-regulate their metabolic scope to support locomotion

Camille Bonneaud, Robbie S. Wilson & Frank Seebacher
Energy-based trade-offs occur when investment in one fitness-related trait diverts energy away from other traits. The extent to which such trade-offs are shaped by limits on the rate of conversion of energy ingested in food (e.g. carbohydrates) into chemical energy (ATP) by oxidative metabolism rather than by the amount of food ingested in the first place is, however, unclear. Here we tested whether the ATP required for mounting an immune response will lead to a...

Data from: Symmetry-breaking phase transitions in highly concentrated semen

Adama Creppy, Franck Plouraboué, Olivier Praud, Xavier Druart, Sébastien Cazin, Hui Yu & Pierre Degond
New experimental evidence of self-motion of a confined active suspension is presented. Depositing fresh semen sample in an annular shaped microfluidic chip leads to a spontaneous vortex state of the fluid at sufficiently large sperm concentration. The rotation occurs unpredictably clockwise or counterclockwise and is robust and stable. Furthermore, for highly active and concentrated semen, richer dynamics can occur such as self-sustained or damped rotation oscillations. Experimental results obtained with systematic dilution provide a clear...

Data from: Gauging scale effects and biogeographical signals in similarity distance decay analyses: an Early Jurassic ammonite case study

Axelle Zacaï, Arnaud Brayard, Jean-Louis Dommergues, Christian Meister, Gilles Escarguel, Rémi Laffont, Bruno Vrielynck & Emmanuel Fara
In biogeography, the similarity distance decay (SDD) relationship refers to the decrease in compositional similarity between communities with geographical distance. Although representing one of the most widely used relationships in biogeography, a review of the literature reveals that: (1) SDD is influenced by both spatial extent and sample size; (2) the potential effect of the phylogenetic level has yet to be tested; (3) the effect of a marked biogeographical structuring upon SDD patterns is largely...

Data from: Forward modeling the rubber hand: illusion of ownership modifies motor-sensory predictions by the brain

Laura Aymerich-Franch, Damien Petit, Gowrishankar Ganesh & Abderrahmane Kheddar
The question of how we attribute observed body parts as our own, and the consequences of this attribution on our sensory-motor processes, is fundamental to understand how our brain distinguishes between self and other. Previous studies have identified interactions between the illusion of ownership, and multi-sensory integration and cross-sensory predictions by the brain. Here we show that illusory ownership additionally modifies the motor-sensory predictions by the brain. In our preliminary experiments, we observed a new...

Data from: Developmental mechanisms of stripe patterns in rodents

Ricardo Mallarino, Corneliu Henegar, Mercedes Mirasierra, Marie Manceau, Carsten Schradin, Mario Vallejo, Slobodan Beronja, Gregory S. Barsh & Hopi E. Hoekstra
Mammalian colour patterns are among the most recognizable characteristics found in nature and can have a profound impact on fitness. However, little is known about the mechanisms underlying the formation and subsequent evolution of these patterns. Here we show that, in the African striped mouse (Rhabdomys pumilio), periodic dorsal stripes result from underlying differences in melanocyte maturation, which give rise to spatial variation in hair colour. We identify the transcription factor ALX3 as a regulator...

Data from: The influence of weather conditions during gestation on life histories in a wild Arctic ungulate

Mathieu Douhard, Leif Egil Loe, Audun Stien, Christophe Bonenfant, R. Justin Irvine, Vebjørn Veiberg, Erik Ropstad & Steve Albon
The internal predictive adaptive response (internal PAR) hypothesis predicts that individuals born in poor conditions should start to reproduce earlier if they are likely to have reduced performance in later life. However, whether this is the case remains unexplored in wild populations. Here, we use longitudinal data from a long-term study of Svalbard reindeer to examine age-related changes in adult female life-history responses to environmental conditions experienced in utero as indexed by rain-on-snow (ROSutero). We...

Data from: Evidence for parasite-mediated selection during short-lasting toxic algal blooms

François Blanquart, Myriam Valero, Catharina Alves-De-Souza, Aliou Dia, Frédéric Lepelletier, Estelle Bigeard, Christian Jeanthon, Christophe Destombe & Laure Guillou
Parasites play a role in the control of transient algal blooms, but it is not known whether parasite-mediated selection results in coevolution of the host and the parasites over this short time span. We investigated the presence of coevolution between the toxic dinoflagellate Alexandrium minutum and two naturally occurring endoparasites during blooms lasting a month in two river estuaries, using cross-inoculation experiments across time and space. Higher parasite abundance was associated with a large daily...

Data from: Evaluating the impact of genomic data and priors on Bayesian estimates of the angiosperm evolutionary timescale

Charles S. P. Foster, Hervé Sauquet, Marlien Van Der Merwe, Hannah McPherson, Maurizio Rossetto & Simon Y. W. Ho
The evolutionary timescale of angiosperms has long been a key question in biology. Molecular estimates of this timescale have shown considerable variation, being influenced by differences in taxon sampling, gene sampling, fossil calibrations, evolutionary models, and choices of priors. Here, we analyze a data set comprising 76 protein-coding genes from the chloroplast genomes of 195 taxa spanning 86 families, including novel genome sequences for 11 taxa, to evaluate the impact of models, priors, and gene...

Data from: Forecasting potential emergence of zoonotic diseases in Southeast Asia: network analysis identifies key rodent hosts

Frédéric Bordes, Alexandre Caron, Kim Blasdell, Michel De Garine-Wichatitsky & Serge Morand
1. Within complex ecological systems, identifying animal species likely to play a key role in the emergence of infectious zoonotic diseases remains a major challenge. One approach consists of using information on current ecological and parasitological similarities among host species in order to predict the most likely pathways for future pathogen spillover. 2. Using field data acquired from 15 sympatric rodent species in various habitats in Thailand, Cambodia and Laos, we built networks based on...

Data from: Food availability and predation risk, rather than intrinsic attributes are the main factors shaping the reproductive decisions of a long-lived predator

Sarah R. Hoy, Alexandre Millon, Steve J. Petty, D Philip Whitfield & Xavier Lambin
Deciphering the causes of variation in reproductive success is a fundamental issue in ecology, as the number of offspring produced is an important driver of individual fitness and population dynamics. Little is known however, about how different factors interact to drive variation in reproduction, such as whether an individual's response to extrinsic conditions (e.g. food availability or predation) varies according to its intrinsic attributes (e.g. age, previous allocation of resources towards reproduction). We used 29...

Data from: How social network structure affects decision-making in Drosophila melanogaster

Cristian Pasquaretta, Marine Battesti, Elizabeth Klenschi, Christophe A. H. Bousquet, Cedric Sueur & Frederic Mery
Animals use a number of different mechanisms to acquire crucial information. During social encounters animals can pass information from one to another but, ideally, they would only use information that benefits survival and reproduction. Therefore, individuals need to be able to determine the value of the information they receive. One cue can come from the behaviour of other individuals that are already using the information. Here we study how individual decision-making is influenced by the...

Data from: Genetic variation in aggregation behaviour and interacting phenotypes in Drosophila

Anne Sophie Philippe, Raphael Jeanson, Cristian Pasquaretta, Francois Rebaudo, Cedric Sueur & Frederic Mery
Aggregation behaviour is the tendency for animals to group together which may have important consequences on individual fitness. We used a combination of experimental and simulation approaches to study how genetic variation and social environment interact to influence aggregation dynamics in Drosophila. To do this, we use two different natural lines of Drosophila that arise from a polymorphism in the foraging gene (“rovers” and “sitters”). We placed groups of flies in a heated arena. Flies...

Data from: Does diet drive the evolution of head shape and bite force in chameleons of the genus Bradypodion?

Alexis Y. Dollion, G. John Measey, Raphael Cornette, Liza Carne, Krystal A. Tolley, Jessica M. Da Silva, Renaud Boistel, Anne-Claire Fabre & Anthony Herrel
The head is a complex integrated system that is implicated in many vital functions. As such, its morphology is impacted by different and sometimes conflicting demands. Consequently, head shape varies greatly depending on the environment and dietary ecology of an organism. Moreover, given its role in territory defence and mating in lizards, it is also subjected to strong sexual selection in these animals. We investigated the relationships between head shape, bite performance and diet in...

Data from: Revisiting the ichthyodiversity of Java and Bali through DNA barcodes: taxonomic coverage, identification accuracy, cryptic diversity and identification of exotic species

Hadi Dahruddin, Aditya Hutama, Frédéric Busson, Sopian Sauri, Robert Hanner, Philippe Keith, Renny Hadiaty & Nicolas Hubert
Among the 899 species of freshwater fishes reported from Sundaland biodiversity hotspot, nearly 50% are endemics. The functional integrity of aquatic ecosystems is currently jeopardized by human activities, and landscape conversion led to the decline of fish populations in several part of Sundaland, particularly in Java. The inventory of the Javanese ichthyofauna has been discontinuous, and the taxonomic knowledge is scattered in the literature. This study provides a DNA barcode reference library for the inland...

Data from: Constrasting global genetic patterns in two biologically similar, widespread and invasive Ciona species (Tunicata, Ascidiacea)

Sarah Bouchemousse, John D. D. Bishop & Frédérique Viard
Human-mediated dispersal interplays with natural processes and complicates understanding of the biogeographical history of species. This is exemplified by two invasive tunicates, Ciona robusta (formerly Ciona intestinalis type A) and C. intestinalis (formerly Ciona intestinalis type B), globally distributed and sympatric in Europe. By gathering new mitochondrial sequences that were merged with published datasets, we analysed genetic patterns in different regions, with a focus on 1) their sympatric range and 2) allopatric populations in N...

Data from: Kin effects on energy allocation in group-living ground squirrels

Vincent A. Viblanc, Claire Saraux, Jan O. Murie & F. Stephen Dobson
The social environment has potent effects on individual phenotype and fitness in group-living species. We asked whether the presence of kin might act on energy allocation, a central aspect of life-history variation. Using a 22-year data set on reproductive and somatic allocations in Columbian ground squirrels (Urocitellus columbianus), we tested the effects of co-breeding and non-breeding kin on the fitness and energy allocation balance between reproduction and personal body condition of individual females. Greater numbers...

Data from: Shifts and linkages of functional diversity between above- and below-ground compartments along a flooding gradient

Corentin Abgrall, Matthieu Chauvat, Estelle Langlois, Mickaël Hedde, David Mouillot, Sandrine Salmon, Bruna Winck & Estelle Forey
Trait-based approaches have the potential to reveal general and predictive relationships between organisms and ecosystem functioning. However, the mechanisms underlying the functional structure of communities are still unclear. Within terrestrial ecosystems, several studies have shown that many ecological processes are controlled by the interacting above- and below-ground compartments. However, few studies have used traits to reveal the functional relationships between plants and soil fauna. Mostly, research combining plants and soil fauna solely used the traits...

Data from: Spatial scale and intraspecific trait variability mediate assembly rules in alpine grasslands

Loïc Chalmandrier, Tamara Münkemüller, Marie-Pascale Colace, Julien Renaud, Serge Aubert, Bradley Z. Carlson, Jean Christophe Clement, Nicolas Legay, Gilles Pellet, Amélie Saillard, Sebastien Lavergne & Wilfried Thuiller
Assembly of grassland communities has long been scrutinized through the lens of functional diversity. Studies generally point to an overwhelming influence of climate on observed patterns of functional diversity, despite experimental evidence demonstrating the importance of biotic interactions. We postulate that this is because most observational studies neglect both scale dependencies of assembly processes and phenotypic variation between individuals. Here, we test for changes in the importance of abiotic filtering and biotic interactions along a...

Data from: Oral samples as non-invasive proxies for assessing the composition of the rumen microbial community

Ilma Tapio, Kevin J. Shingfield, Nest McKain, Aurelie Bonin, Daniel Fischer, Ali R. Bayat, Johanna Vilkki, Pierre Taberlet, Timothy J. Snelling & R. John Wallace
Microbial community analysis was carried out on ruminal digesta obtained directly via rumen fistula and buccal fluid, regurgitated digesta (bolus) and faeces of dairy cattle to assess if non-invasive samples could be used as proxies for ruminal digesta. Samples were collected from five cows receiving grass silage based diets containing no additional lipid or four different lipid supplements in a 5 x 5 Latin square design. Extracted DNA was analysed by qPCR and by sequencing...

Data from: Spatial representativeness of environmental DNA metabarcoding signal for fish biodiversity assessment in a natural freshwater system

Raphaël Civade, Tony Dejean, Alice Valentini, Nicolas Roset, Jean-Claude Raymond, Aurélie Bonin, Pierre Taberlet & Didier Pont
In the last few years, the study of environmental DNA (eDNA) has drawn attention for many reasons, including its advantages for monitoring and conservation purposes. So far, in aquatic environments, most of eDNA research has focused on the detection of single species using species-specific markers. Recently, species inventories based on the analysis of a single generalist marker targeting a larger taxonomic group (eDNA metabarcoding) have proven useful for bony fish and amphibian biodiversity surveys. This...

Data from: The oxidative cost of reproduction depends on early development oxidative stress and sex in a bird species

Ana Angela Romero Haro, Gabriele Sorci, Carlos Alonso-Alvarez & A. A. Romero-Haro
In the early 2000’s, a new component of the cost of reproduction was proposed: oxidative stress. Since then the oxidative cost of reproduction hypothesis has, however, received mixed support. Different arguments have been provided to explain this. Among them, the lack of a life history perspective on most experimental tests was suggested. We manipulated the levels of a key intracellular antioxidant (glutathione) in captive zebra finches (Taeniopygia guttata) during a short period of early life...

Data from: New material of Palaeoamasia kansui (Embrithopoda, Mammalia) from the Eocene of Turkey and a phylogenetic analysis of Embrithopoda at the species level

Ozan Erdal, Pierre-Olivier Antoine & Sevket Sen
Since the discovery of the megaherbivore Arsinoitherium zitteli Beadnell (early Oligocene of Egypt), the extinct order Embrithopoda has remained an enigmatic group, with disputed affinities among ungulates. In this study, new specimens of Palaeoamasia kansui from the early Palaeogene of Turkey are described and a synthetic dental terminology is proposed for embrithopods. Based on 130 cranial–mandibular and dental characters, the first phylogenetic analysis of embrithopods is carried out in aim to enhance the position of...

Data from: The genome of the yellow potato cyst nematode Globodera rostochiensis reveals insights into the basis of parasitism and virulence

Sebastian Eves-Van Den Akker, Dominik Laetsch, Peter Thorpe, Catherine Lilley, Etienne Danchin, Martine Da Rocha, Corinne Rancurel, Nancy Holroyd, James Cotton, Amir Szitenberg, Eric Grenier, Josselin Montarry, Benjamin Mimee, Marc-Olivier Duceppe, Ian Boyes, Jessica Marvin, Laura Jones, Hazijah Yusup, Joël Lafond-Lapalme, Magali Esquibet, Michael Sabeh, Michael Rott, Hein Overmars, Anna Finkers-Tomczak, Geert Smant … & John Jones
Background: The yellow potato cyst nematode Globodera rostochiensis is a devastating plant pathogen of global economic importance. This biotrophic parasite secretes effectors from pharyngeal glands, some of which were acquired by horizontal gene transfer, to manipulate host processes and promote parasitism. G. rostochiensis is classified into pathotypes with different plant resistance-breaking phenotypes. Results: We generate a high-quality genome assembly for G. rostochiensis pathotype Ro1, identify putative effectors and horizontal gene transfer events, map gene expression...
