Data from: Genetic variability and transgenerational regulation of investment in sex in the monogonont rotifer Brachionus plicatilis

Denis Roze, Océane Seudre, Eloïse Vanhoenacker, Stéphane Mauger & Jérôme Coudret
In cyclical parthenogens such as aphids, cladocerans and rotifers, the coupling between sexual reproduction and the production of resting stages (diapausing eggs) imposes strong constraints on the timing of sex. While induction of sex is generally triggered by environmental cues, the response to such cues may vary across individuals according to genetic and non-genetic factors. In this study, we explored genetic and epigenetic causes of variation for the propensity for sex using a collection of...

Data from: Assessing the effects of quantitative host resistance on the life-history traits of sporulating parasites with growing lesions

Melen Leclerc, Julie Clément, Didier Andrivon & Frédéric Hamelin
Assessing life-history traits of parasites on resistant hosts is crucial in evolutionary ecology. In the particular case of sporulating pathogens with growing lesions, phenotyping is difficult because one needs to disentangle properly pathogen spread from sporulation. By considering Phytophthora infestans on potato, we use mathematical modelling to tackle this issue and refine the assessment pathogen response to quantitative host resistance. We elaborate a parsimonious leaf-scale model by convolving a lesion growth model and a sporulation...

Data from: Evidence for arrested succession in a liana‐infested Amazonian forest

Blaise Tymen, Maxime Réjou-Méchain, James W. Dalling, Sophie Fauset, Ted R. Feldausch, Natalia Norden, Oliver L. Phillips, Benjamin L. Turner, Jérôme Viers & Jérôme Chave
1. Empirical evidence and modelling both suggest that global changes may lead to an increased dominance of lianas, and thus to an increased prevalence of liana-infested forest formations in tropical forests. The implications for tropical forest structure and the carbon cycle remain poorly understood. 2. We studied the ecological processes underpinning the structure and dynamics of a liana-infested forest in French Guiana, using a combination of long-term surveys (tree, liana, seedling and litterfall), soil chemical...

Data from: Correlations between broad-scale taxonomic and genetic differentiations suggest a dominant imprint of historical processes on beta diversities

Marine Robuchon, Boris Leroy, Céline Jézéquel & Bernard Hugueny
Aim: Dispersal limitation, environmental selection and drift are known to influence both taxonomic similarity between communities and genetic similarity between populations. However, disentangling the relative roles of these processes on spatial patterns of differentiation - whether regarding taxonomic differentiation between communities or genetic differentiation between populations - is challenging. Investigating whether spatial patterns of taxonomic differentiation and genetic differentiation are correlated (β-SGDCs) is a promising approach to address this issue. Here, we investigated β-SGDCs over...

Data from: Out of the Mediterranean? post-glacial colonisation pathways varied among cold-water coral species

Joana Boavida, Ronan Becheler, Marvin Choquet, Norbert Frank, Marco Taviani, Jean-Francois Bourillet, Anne-Leila Meistertzheim, Anthony Grehan, Alessandra Savini & Sophie Arnaud-Haond
Aim. To infer cold-water corals' post-glacial phylogeography and assess the role of Mediterranean Sea glacial refugia as origins for the recolonisation of the northeastern Atlantic Ocean. Location. Northeastern Atlantic Ocean and Mediterranean Sea. Taxon. Lophelia pertusa, Madrepora oculata. Methods. We sampled cold-water corals using remotely operated vehicles and one sediment core for coral and sediment dating. We characterized spatial genetic patterns (microsatellites and a nuclear gene fragment) using networks, clustering and measures of genetic differentiation....

Data from: Why has transparency evolved in aposematic butterflies? insights from the largest radiation of aposematic butterflies, the Ithomiini

Melanie McClure, Corentin Clerc, Charlotte Desbois, Aimilia Meichanetzoglou, Marion Cau, Lucie Bastin-Héline, Javier Bacigalupo, Céline Houssin, Charline Pinna, Bastien Nay, Violaine Llaurens, Serge Berthier, Christine Andraud, Doris Gomez & Marianne Elias
Defended species are often conspicuous and this is thought to be an honest signal of defences, i.e. more toxic prey are more conspicuous. Neotropical butterflies of the large Ithomiini tribe numerically dominate communities of chemically-defended butterflies and may thus drive the evolution of mimetic warning patterns. Although many species are brightly coloured, most are transparent to some degree. The evolution of transparency from a warningly coloured ancestor is puzzling as it is generally assumed to...

Data from: Where and What? Frugivory is associated with more efficient foraging in three semi-free ranging primate species

Cinzia Trapanese, Benjamin Robira, Giordana Tonachella, Silvia Di Gristina, Hélène Meunier & Shelly Masi
Foraging in seasonal environments can be cognitively challenging. Comparative studies have associated brain size with a frugivorous diet. We investigated how fruit distribution (where) and preference (what) affect foraging decisions in three semi-free ranging primate species with different degrees of frugivory: Macaca tonkeana (Nindiv=5; Ntrials=430), M. fascicularis (Nindiv=3; Ntrials=168) and Sapajus apella (Nindiv=6; Ntrials=288). We used 36 boxes fixed on trees and filled with highly and less preferred fruits with different (weekly) spatio-temporal distributions. Individuals...

Data from: The theory of island biogeography and soundscapes: species diversity and the organization of acoustic communities

Aloïs Robert, Thierry Lengagne, Martim Melo, Vanessa Gardette, Sacha Julien, Rita Covas, Doris Gomez & Claire Doutrelant
Aim: On islands, species richness is reduced and interspecific competition relaxed in relation to the mainland, allowing species to use broader ecological niches. These factors are known to affect diet and morphology, but can also affect communication and acoustic signaling in particular. However, no study has ever compared insular and continental soundscapes to determine to which extent islands present reduced acoustic richness (number of co-vocalizing species) and fewer constraints for vocalizing species. Location: São Tomé...

Data from: Natural Wolbachia infections are common in the major malaria vectors in Central Africa

Diego Ayala, Ousman Akone-Ella, Nil Rahola, Pierre Kengne, Marc F. Ngangue, Fabrice Mezeme, Boris K. Makanga, Martha Nigg, Carlo Costantini, Frederic Simard, Franck Prugnolle, Benjamin Roche, Olivier Duron & Christophe Paupy
During the last decade, the endosymbiont bacterium Wolbachia has emerged as a biological tool for vector disease control. However, for long time, it was believed that Wolbachia was absent in natural populations of Anopheles. The recent discovery that species within the Anopheles gambiae complex host Wolbachia in natural conditions has opened new opportunities for malaria control research in Africa. Here, we investigated the prevalence and diversity of Wolbachia infection in 25 African Anopheles species in...

3D models of planetary bodies

Frederic Schmidt, Gaspard Salomon & Laurent Daumas
Current technology allows us to print various object in 3D for teaching and education purposes, including for the visually disabled [1]. The use of 3D printer for planetary science has been perceived since the premises of this industrial revolution [2]. In parallel several services and web-services have been developed to help the users to create their own model [3]. We propose here a database of ready-to-use 3D model of planetary bodies at full scale.

Data from: Functional integration for enrolment constrains evolutionary variation of phacopid trilobites despite developmental modularity

Morgane Oudot, Pascal Neige, Rémi Laffont, Nicolas Navarro, Ahmed Yacine Khaldi & Catherine Crônier
Modularity and integration are variational properties expressed at various levels of the biological hierarchy. Mismatches among these levels, for example developmental modules that are integrated in a functional unit, could be informative of how evolutionary processes and trade‐offs have shaped organismal morphologies as well as clade diversification. In the present study, we explored the full, integrated and modular spaces of two developmental modules in phacopid trilobites, the cephalon and the pygidium, and highlight some differences...

Data from: Running in circles in phylomorphospace: host environment constrains morphological diversification in parasitic wasps

Bernardo F. Santos, Adrien Perrard & Seán G. Brady
Understanding phenotypic diversification and the conditions that spur morphological novelty or constraint is a major theme in evolutionary biology. Unequal morphological diversity between sister clades can result from either differences in the rate of morphological change or in the ability of clades to explore novel phenotype ranges. We combine an existing phylogenetic framework with new phylogenomic data and geometric morphometrics to explore the relative roles of rate versus mode of morphological evolution for a hyperdiverse...

Data from: Failure to coordinate management in transboundary populations hinders the achievement of national management goals: the case of wolverines in Scandinavia

Vincenzo Gervasi
1. Large carnivores are expanding in Europe, and their return is associated with conflicts that often result in policies to regulate their population size through culling. Being wide-ranging species, their populations are often distributed across several jurisdictions, which may vary in the extent to which they use lethal control. This creates the conditions for the establishment of source-sink dynamics across borders, which may frustrate the ability of countries to reach their respective management objectives. 2....

Data from: Hormonal pleiotropy and the evolution of allocation trade-offs

Salomé Bourg, Laurent Jacob, Frédéric Menu & Etienne Rajon
Recent empirical evidence suggest that trade-off relationships can evolve, challenging the classical image of their high entrenchment. For energy reliant traits, this relationship should depend on the endocrine system that regulates resource allocation. Here we model changes in this system by mutating the expression and conformation of its constitutive hormones and receptors. We show that the shape of trade-offs can indeed evolve in this model through the combined action of genetic drift and selection, such...

Data from: Population closure and the bias-precision trade-off in Spatial Capture-Recapture

Pierre Dupont, Cyril Milleret, Olivier Gimenez & Richard Bischof
1. Spatial capture-recapture (SCR) is an increasingly popular method for estimating ecological parameters. This method often relies on data collected over relatively long sampling periods. While longer sampling periods can yield larger sample sizes and thus increase precision of estimates, they also increase the risk of violating the closure assumption, thereby potentially introducing bias. The sampling period characteristics are therefore likely to play an important role in this bias-precision tradeoff. Yet few studies have studied...

Data from: The preference-performance relationship as a means of classifying parasitoids according to their specialization degree

Lucie S. Monticelli, Le Thu Ha Nguyen, Edwige Amiens-Desneux, Chen Luo, Anne-Violette Lavoir, Jean-Luc Gatti & Nicolas Desneux
Host range in parasitoids could be described by the preference-performance hypothesis (PPH) where preference is defined as host acceptance and performance is defined as the sum of all species on which parasitoid offspring can complete their life cycle. The PPH predicts that highly suitable hosts will be preferred by ovipositing females. However, generalist parasitoids may not conform to this hypothesis if they attack a large range of hosts of varying suitability. Under laboratory conditions, we...

Data from: At sea vocal repertoire of a foraging seabird

Andréa Thiebault, Isabelle Charrier, Pierre Pistorius & Thierry Aubin
Seabirds spend most of their time at sea, yet our knowledge of their activities and behaviour is limited due to difficulties of in-situ data collection. In particular, we know virtually nothing about their acoustic communication when at sea. We benefited from the recent development of miniaturised audio-recording devices to deployacoustic recorders on breeding Cape gannets Morus capensis to study their vocal activity while foraging. Call sequences were recorded on 1718 occasions, from which acoustic variables...

Data from: Metapopulation vicariance, age of island taxa and dispersal: a case study using the pacific plant genus Planchonella (Sapotaceae)

Ulf Swenson, J. Christopher Havran, Jérôme Munzinger, Stephen Mcloughlin & Stephan Nylinder
Oceanic islands originate from volcanism or tectonic activity without connections to continental landmasses, are colonized by organisms, and eventually vanish due to erosion and subsidence. Colonization of oceanic islands occurs through long-distance dispersals or metapopulation vicariance, the latter resulting in lineages being older than the islands they inhabit. If metapopulation vicariance is valid, island ages cannot be reliably used to provide maximum age constraints for molecular dating. We explore the relationships between the ages of...

Sexual isolation with and without ecological isolation in marine isopods Jaera albifrons and J. praehirsuta

Ambre Ribardière, Elsa Pabion, Jérôme Coudret, Claire Daguin-Thiébaut, Céline Houbin, Stéphane Loisel, Sébastien Henry & Thomas Broquet
Sexual barriers associated with mate choice are often found to be associated with some level of ecological isolation between species. The independence and relative strength of sexual isolation are thus difficult to assess. Here we take advantage of a pair of marine isopod species (Jaera albifronsand J. praehirsuta) that show sexual isolation and coexist in populations where they share the same microhabitat or not (i.e. without or with ecological isolation). We estimated the strength of...

Nicolas Mouquet, Anne Sophie Tribot, Julie Deter, Thomas Claverie, François Guillhaumon & Sebastien Villéger
Data set corresponding to the manuscript : "Species diversity and composition drive the aesthetic value of coral reef fish assemblages".

Data from: The geographical variation of network structure is scale dependent: understanding the biotic specialization of host-parasitoid networks

Nuria Galiana, Bradford A. Hawkins & Jose M. Montoya
Research on the structure of ecological networks suggests that a number of universal patterns exist. Historically, biotic specialization has been thought to increase towards the Equator. Yet, recent studies have challenged this view showing non-conclusive results. Most studies analysing the geographical variation in biotic specialization focus, however, only on the local scale. Little is known about how the geographical variation of network structure depends on the spatial scale of observation (i.e., from local to regional...

Data from: Gene copy number variations as signatures of adaptive evolution in the parthenogenetic, plant-parasitic nematode Meloidogyne incognita

Philippe Castagnone-Sereno, Karine Mulet, Etienne G. J. Danchin, Georgios D. Koutsovoulos, Mégane Karaulic, Martine Da Rocha, Marc Bailly-Bechet, Loris Pratx, Laetitia Perfus-Barbeoch & Pierre Abad
Adaptation to changing environmental conditions represents a challenge to parthenogenetic organisms and until now, how phenotypic variants are generated in clones in response to the selection pressure of their environment remains poorly known. The obligatory parthenogenetic root-knot nematode species Meloidogyne incognita has a worldwide distribution and is the most devastating plant-parasitic nematode. Despite its asexual reproduction, this species exhibits an unexpected capacity of adaptation to environmental constraints, e.g., resistant hosts. Here we used a genome-wide...

Data from: Redescription of Arganasaurus (Metoposaurus) azerouali (Dutuit) comb. nov. from the Late Triassic of the Argana Basin (Morocco), and the first phylogenetic analysis of the Metoposauridae (Amphibia, Temnospondyli)

Valentin Buffa, Nour-Eddine Jalil & J. Sébastien Steyer
A systematic revision of the temnospondyl ‘Metoposaurus’ azerouali Dutuit from the Late Triassic of the Argana Basin (Western High Atlas, Morocco) is presented. The type material is redescribed in detail, and a preliminary phylogenetic analysis – the first one dealing with all metoposaurid species – is also conducted in order to test its position within the Metoposauridae. Our analysis places ‘Metoposaurus’ azerouali as sister‐taxon to Arganasaurus lyazidi in a robust clade supported by two unambiguous...

Data from: Postglacial colonization routes coincide with a life history breakpoint along a latitudinal gradient

Emilien Luquet, Patrik Rödin-Mörch, Maria Cortazar-Chinarro, Yvonne Meyer-Lucht, Jacob Höglund & Anssi Laurila
While adaptive divergence along environmental gradients has repeatedly been demonstrated, the role of postglacial colonization routes in determining phenotypic variation along gradients has received little attention. Here we used a hierarchical QST-FST approach to separate the roles of adaptive and neutral processes in shaping phenotypic variation in moor frog (Rana arvalis) larval life-histories along a 1700 km latitudinal gradient across northern Europe. This species has colonized Scandinavia via two routes with a contact zone in...

Data from: Male vocalizations convey information on kinship and inbreeding in a Lekking bird

Clément Cornec, Alexandre Robert, Fanny Rybak & Yves Hingrat
Kinship and inbreeding are two major components involved in sexual selection and mating system evolution. However, the mechanisms underlying recognition and discrimination of genetically related or inbred individuals remain unclear. We investigated whether kinship and inbreeding information is related to low frequency vocalizations, “booms”, produced by males during their courtship in the lekking houbara bustard (Chlamydotis undulata undulata). Based on a captive breeding programme where the pedigree of all males is known, we investigated the...
