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: 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: 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: 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: 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: 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...

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: 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: The wing venation of the Protomyrmeleontidae (Insecta: Odonatoptera) reconsidered thanks to a new specimen from Molteno (Triassic; South Africa)

Isabelle Deregnaucourt, Torsten Wappler, John M. Anderson & Olivier Béthoux
Wing venation homologies of the Protomyrmeleontidae, a widespread group of damselfly-like stem-Odonata during the Triassic, are debated. The two main interpretations essentially disagree on the identification of RP branches. Indeed, Protomyrmeleontidae display a very complex wing venation necessarily involving, in a way or another, fusions of the concave RP branches with the convex intercalary veins. As a consequence, vein elevations in the radial area are challenging to interpret. Here, we present a new Triassic specimen...

Data from: Local predation risk and matrix permeability interact to shape movement strategy

Laurane Winandy, Julien Cote, Lucie Di Gesu, Felix Pellerin, Audrey Trochet & Delphine Legrand
In fragmented landscapes, the reduced connectivity among patches drives the evolution of movement strategies through an increase of transience costs. Reduced movements may further alter heterogeneity in biotic and abiotic conditions experienced by individuals. The joint action of local conditions and matrix permeability may shape emigration decisions. Here, we tested the interactive effects of predation risk and matrix permeability on movement propensity, movement costs and movers’ phenotype in the common toad Bufo bufo. In a...

Data from: Context-dependent signaling of coincident auditory and visual events in primary visual cortex

Thomas Deneux, Evan R. Harrell, Alexandre Kempf, Sebastian Ceballo, Anton Filipchuk & Brice Bathellier
Detecting rapid, coincident changes across sensory modalities is essential for recognition of sudden threats or events. Using two-photon calcium imaging in identified cell types in awake, head-fixed mice, we show that, among the basic features of a sound envelope, loud sound onsets are a dominant feature coded by the auditory cortex neurons projecting to primary visual cortex (V1). In V1, a small number of layer 1 interneurons gates this cross-modal information flow in a context-dependent...

Individual variation in age-dependent reproduction: fast explorers live fast but senesce young?

Niels Dingemanse, Maria Moiron, Yimen G. Araya-Ajoy, Alexia Mouchet & Robin N. Abbey-Lee
1. Adaptive integration of life history and behaviour is expected to result in variation in the pace-of-life. Previous work focused on whether “risky” phenotypes live-fast-but-die-young, but reported conflicting support. We posit that individuals exhibiting risky phenotypes may alternatively invest heavily in early-life reproduction but consequently suffer greater reproductive senescence. 2. We used a 7-year longitudinal dataset with >1200 breeding records of >800 female great tits assayed annually for exploratory behaviour to test whether within-individual age-dependency...

Data from: How many cubs can a mum nurse? Maternal age and size influence litter size in polar bears

Dorinda Marie Folio, Jon Aars, Olivier Gimenez, Andrew E. Derocher, Oystein Wiig & Sarah Cubaynes
Life history theory predicts that females' age and size affect the level of maternal investment in current reproduction, balanced against future reproductive effort, maintenance and survival. Using long-term (30 years) individual data on 193 female polar bears (Ursus maritimus), we assessed age- and size-specific variation on litter size. Litter size varied with maternal age, younger females had higher chances of losing a cub during their first months of life. Results suggest an improvement of reproductive...

Data from: How do soil microorganisms respond to N, P and NP additions? Application of the ecological framework of (co‐)limitation by multiple resources

Beibei Ma, Xiaolong Zhou, Qi Zhang, Mingsen Qin, Linggang Hu, Kena Yang, Zhen Xie, Wenbin Ma, Beibei Chen, Huyuan Feng, Yongjun Liu, Guozhen Du, Xiaojun Ma & Xavier Le Roux
1.Nitrogen, N, and phosphorus, P, often limit biological processes in terrestrial ecosystems. Based on previous studies mainly focusing on plants, the concept of resource limitation has evolved towards a theory of (co)limitations by multiple‐resources. However, this ecological framework has not been applied to analyse how soil microorganisms and plants concurrently respond to N and/or P addition, and whether these responses are constrained by phylogenetic relatedness. 2.Here, we applied this framework to analyse microbial and plant...

Data from: Genetic homogenization of indigenous sheep breeds in Northwest Africa

Ibrahim Belabdi, Abdessamad Ouhrouch, Mohamed Lafri, Semir Bechir Suheil Gaouar, Elena Ciani, Ahmed Redha Benali, Hakim Ould Ouelhadj, Abdelmajid Haddioui, François Pompanon, Véronique Blanquet, Dominique Taurisson-Mouret, Sahraoui Harkat, Johannes A. Lenstra, Badr Benjelloun & Anne Da Silva
Northwest-African sheep represent an ideal case-study for assessing the potential impact of genetic homogenization as a threat to the future of traditional breeds that are adapted to local conditions. We studied ten Algerian and Moroccan breeds of sheep, including three transboundary breeds, distributed over a large part of the Maghreb region, which represents a geographically and historically coherent unit. Our analysis of the dataset that involved carrying out Genome-wide SNP genotyping, revealed a high level...

Data from: The global geography of fish diadromy modes

Anaïs Chalant, Céline Jézequel, Philippe Keith & Bernard Hugueny
Aim: Geographical gradients in resource production are likely to translate into macro-ecological patterns in the biodiversity of migratory organisms but few studies have addressed this question at a global scale. Here we tested a hypothesis based on uncoupled latitudinal gradients in marine and freshwater primary productivities aimed at explaining where (e. g. at which latitude) and at which stage of the life cycle (larvae: amphidromy, juvenile: catadromy, adult: anadromy) migration from ocean to freshwater occurs...

Data from: Transparency reduces predator detection in mimetic clearwing butterflies

Mónica Arias, Johanna Mappes, Charlotte Desbois, Swanne Gordon, Melanie McClure, Marianne Elias, Ossi Nokelainen & Doris Gomez
1. Predation is an important selective pressure and some prey have evolved conspicuous warning signals that advertise unpalatability (i.e. aposematism) as an antipredator defence. Conspicuous colour patterns have been shown effective as warning signals, by promoting predator learning and memory. Unexpectedly, some butterfly species from the unpalatable tribe Ithomiini possess transparent wings, a feature rare on land but common in water, known to reduce predator detection. 2. We tested if transparency of butterfly wings was...

Data from: Are house sparrow populations limited by the lack of cavities in urbanized landscapes? an experimental test.

Frédéric Angelier & François Brischoux
Current urban policies are associated with deep changes in urban structures, which may impoverish urban biodiversity. A major concern is the disappearance of nesting sites for wild vertebrate species living in urban areas. New urban structures without any cracks or cavities may especially preclude cavity nesters from breeding in cities and they may cause population declines. In that context, we experimentally investigated this question in an urban exploiter bird species (the house sparrow, Passer domesticus),...

Data from: Is telomere length a molecular marker of individual quality? insights from a long-lived bird

Frédéric Angelier, Henri Weimerskirch, Christophe Barbraud & Olivier Chastel
1. In wild vertebrates, some individuals survive and reproduce better than others and this has led to the concept of individual quality. Despite its importance when studying ecological processes and life-history trade-offs, measuring individual quality is complex because individuals must be followed during a large part of their life. 2. Recently, telomere biology has been successfully brought into ecology and telomere length has been suggested to be a promising molecular tool to evaluate individual quality...

Data from: Love them all: mothers provide care to foreign eggs in the European earwig Forficula auricularia

Sophie Van Meyel, Séverine Devers & Joël Meunier
The rejection of foreign individuals is considered a central parameter in the evolution of social life. Within family units, parents are typically thought to reject foreign offspring to ensure that their investment into care is directed towards their own descendants. Whereas selection for such kin bias is expected to be high when parental care is extended and involves numerous and energetically costly behaviours, it can be reduced when the acceptance of foreigners provide subsequent benefits...

Data from: Trade-offs in provisioning and stability of ecosystem services in agroecosystems

Daniel Montoya, Bart Haegeman, Sabrina Gaba, Claire De Mazancourt, Vincent Bretagnolle & Michel Loreau
Changes in land use generate trade-offs in the delivery of ecosystem services in agricultural landscapes. However, we know little about how the stability of ecosystem services responds to landscape composition, and what ecological mechanisms underlie these trade-offs. Here, we develop a model to investigate the dynamics of three ecosystem services in intensively-managed agroecosystems, i.e. pollination-independent crop yield, crop pollination, and biodiversity. Our model reveals trade-offs and synergies imposed by landscape composition that affect not only...

Data from: Sperm competition accentuates selection on ejaculate attributes

Pauline Vuarin, Yves Hingrat, Loïc Lesobre, Michel Saint-Jalme, Frédéric Lacroix & Gabriele Sorci
Ejaculate attributes are important factors driving the probability of fertilizing eggs. When females mate with several males, competition between sperm to fertilize eggs should accentuate selection on ejaculate attributes. We tested this hypothesis in the North African houbara bustard (Chlamydotis undulata undulata) by comparing the strength of selection acting on two ejaculate attributes when sperm from single males or sperm from different males were used for insemination. In agreement with the prediction, we found that...

Data from: Diffusion tensor imaging reveals diffuse white matter injuries in locked-in syndrome patients

Mylène L. Leonard, Felix R. Renard, Laura H. Harsan, Julien P. Pottecher, Marc B. Braun, Francis S. Schneider, Pierre F. Froehlig, Frédéric B. Blanc, Daniel R. Roquet, Sophie A. Achard, Nicolas M. Meyer & Stéphane K. Kremer
Locked-in syndrome (LIS) is a state of quadriplegia and anarthria with preserved consciousness, which is generally triggered by a disruption of specific white matter fiber tracts, following a lesion in the ventral part of the pons. However, the impact of focal lesions on the whole brain white matter microstructure and structural connectivity pathways remains unknown. We used diffusion tensor magnetic resonance imaging (DT-MRI) and tract-based statistics to characterise the whole white matter tracts in seven...
