Data from: Reinvestigation of Protelytron permianum (Insecta; Early Permian; USA) as an example for applying reflectance transformation imaging to insect imprint fossils

Olivier Béthoux, Artémis Llamosi & Séverine Toussaint
We reinvestigated the holotype of Protelytron permianum, one of the earliest putative stem-dermapteran (i.e. stem-earwig). We recurred to reflectance transformation imaging (RTI) to deliver exhaustive and interactive photographic data. We were able to ascertain the occurrence of broadenings located along veins of the hind wing vannus and forming an arc, as well as a series of radiating folds, alternatively concave and convex. Such an organization is diagnostic of Dermaptera, in which it is indicative of...

Data from: Trait-matching and mass effect determine the functional response of herbivore communities to land use intensification

Gaëtane Le Provost, Nicolas Gross, Luca Börger, Hélène Deraison, Marilyn Roncoroni & Isabelle Badenhausser
1. Trait-based approaches represent a promising way to understand how trophic interactions shape animal communities. The approach relies on the identification of the traits that mediate the linkages between adjacent trophic levels, i.e. “trait-matching”. Yet, how trait-matching explains the abundance and diversity of animal communities has been barely explored. This question may be particularly critical in the context of land use intensification, currently threatening biodiversity and associated ecosystem services. 2. We collected a large dataset...

Data from: Comparative tests of the role of dewlap size in Anolis lizard speciation

Travis Ingram, Alexis Harrison, D. Luke Mahler, María Del Rosario Castañeda, Richard E. Glor, Anthony Herrel, Yoel E. Stuart & Jonathan B. Losos
Phenotypic traits may be linked to speciation in two distinct ways: character values may influence the rate of speciation or diversification in the trait may be associated with speciation events. Traits involved in signal transmission, such as the dewlap of Anolis lizards, are often involved in the speciation process. The dewlap is an important visual signal with roles in species recognition and sexual selection, and dewlaps vary among species in relative size as well as...

Data from: Unexpected high vulnerability of functions in wilderness areas: evidence from coral reef fishes

Stephanie D'agata, Laurent Vigliola, Nickolas A.J. Graham, Laurent Wantiez, Valeriano Parravicini, Sébastien Villéger, Gérard Mou-Tham, Phillipe Frolla, Alan M. Friedlander, Michel Kulbicki, David Mouillot & Nicholas A. J. Graham
High species richness is thought to support the delivery of multiple ecosystem functions and services under changing environments. Yet, some species might perform unique functional roles while others are redundant. Thus, the benefits of high species richness in maintaining ecosystem functioning are uncertain if functions have little redundancy, potentially leading to high vulnerability of functions. We studied the natural propensity of assemblages to be functionally buffered against loss prior to fishing activities, using functional trait...

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: Genetic hitchhiking and resistance evolution to transgenic Bt toxins: insights from the African stalk borer Busseola fusca (Noctuidae)

Pascal Campagne, Claire Capdevielle-Dulac, Rémy Pasquet, Stephen J. Cornell, Marlene Vanrooyen-Kruger, Jean-François Silvain, Bruno LeRu & Johnnie Van Den Berg
Since transgenic crops expressing Bacillus thuringiensis (Bt) toxins were first released, resistance evolution leading to failure in control of pests populations has been observed in a number of species. Field resistance of the moth Busseola fusca was acknowledged 8 years after Bt maize was introduced in South Africa. Since then, field resistance of this corn borer has been observed at several locations, raising questions about the nature, distribution and dynamics of the resistance trait. Using...

Data from: Influence of environmental parameters on movements and habitat utilization of humpback whales (Megaptera novaeangliae) in the Madagascar breeding ground

Laurène Trudelle, Salvatore Cerchio, Alexandre N. Zerbini, Ygor Geyer, Francois-Xavier Mayer, Jean-Luc Jung, Maxime R. Hervé, Stéphane Pous, Jean-Baptiste Sallée, Howard C. Rosenbaum, Olivier Adam & Jean-Benoit Charrassin
Assessing the movement patterns and key habitat features of breeding humpback whales is a prerequisite for the conservation management of this philopatric species. To investigate the interactions between humpback whale movements and environmental conditions off Madagascar, we deployed 25 satellite tags in the northeast and southwest coast of Madagascar. For each recorded position, we collated estimates of environmental variables and computed two behavioural metrics: behavioural state of ‘transiting’ (consistent/directional) versus ‘localized’ (variable/non-directional), and active swimming...

Data from: Anthropogenic ecosystem disturbance and the recovery debt

David Moreno Mateos, Edward B. Barbier, Peter C. Jones, Holly P. Jones, James Aronson, Jose A. Lopez-Lopez, Michelle L. McCrackin, Paula Meli, Daniel Montoya & José Rey Benayas
Ecosystem recovery from anthropogenic disturbances, either without human intervention or assisted by ecological restoration, is increasingly occurring worldwide. As ecosystems progress through recovery, it is important to estimate any resulting deficit in biodiversity and functions. Here we use data from 3,035 sampling plots worldwide, to quantify the interim reduction of biodiversity and functions occurring during the recovery process (that is, the ‘recovery debt’). Compared with reference levels, recovering ecosystems run annual deficits of 46–51% for...

Data from: Combining familiarity and landscape features helps break down the barriers between movements and home ranges in a non-territorial large herbivore

Pascal Marchand, Mathieu Garel, Gilles Bourgoin, Antoine Duparc, Dominique Dubray, Daniel Maillard & Anne Loison
Recent advances in animal ecology have enabled identification of certain mechanisms that lead to the emergence of territories and home ranges from movements considered as unbounded. Among them, memory and familiarity have been identified as key parameters in cognitive maps driving animal navigation, but have been only recently used in empirical analyses of animal movements. At the same time, the influence of landscape features on movements of numerous species and on space division in territorial...

Data from: Body reserves mediate trade-offs between life history traits: new insights from small pelagic fish reproduction

Pablo Brosset, Josep Lloret, Marta Muñoz, Christian Fauvel, Elisabeth Van Beveren, Virginie Marques, Jean-Marc Fromentin, Frédéric Ménard & Claire Saraux
Limited resources in the environment prevent individuals from simultaneously maximizing all life-history traits, resulting in trade-offs. In particular, the cost of reproduction is well known to negatively affect energy investment in growth and maintenance. Here, we investigated these trade-offs during contrasting periods of high versus low fish size and body condition (before/after 2008) in the Gulf of Lions. Female reproductive allocation and performance in anchovy (Engraulis encrasicolus) and sardine (Sardina pilchardus) were examined based on...

Data from: Initial genetic diversity enhances population establishment and alters genetic structuring of a newly established Daphnia metapopulation

Christopher J. Holmes, Jelena H. Pantel, Kimberly L. Schulz & Carla E. Cáceres
When newly created habitats are initially colonized by genotypes with rapid population growth rates, later arriving colonists may be prevented from establishing. Although these priority effects have been documented in multiple systems, their duration may be influenced by the diversity of the founding population. We conducted a large-scale field manipulation to investigate how initial clonal diversity influences temporal and landscape patterns of genetic structure in a developing metapopulation. Six genotypes of obligately asexual Daphnia pulex...

Data from: Spatio-temporal modelling of auk abundance after the Erika oil spill and implications for conservation

Kévin Le Rest, Grégoire Certain, Benjamin Debétencourt & Vincent Bretagnolle
Species distribution models are widely used in applied ecology and conservation. While accounting for spatial dependences is now the rule, temporal dependences have rarely been dealt with explicitly. In this study, we analyse wintering auk distribution in the Bay of Biscay and English Channel and estimate changes in abundance within and between years while accounting for space–time dependencies. We then propose a retrospective estimate of the impact of the Erika oil spill that occurred in...

Data from: Adaptation to climate through flowering phenology: a case study in Medicago truncatula

Concetta Burgarella, Nathalie Chantret, Laurène Gay, Jean-Marie Prosperi, Maxime Bonhomme, Peter Tiffin, Nevin D. Young & Joelle Ronfort
Local climatic conditions likely constitute an important selective pressure on genes underlying important fitness-related traits such as flowering time and in many species flowering phenology and climatic gradients strongly covary. To test whether climate shapes genetic variation on flowering time genes and to identify candidate flowering genes involved in the adaptation to environmental heterogeneity, we used a large M. truncatula core collection to examine the association between nucleotide polymorphisms at 224 candidate genes and both...

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: Paternal but not maternal age influences early-life performance of offspring in a long-lived seabird

Rémi Fay, Christophe Barbraud, Karine Delord & Henri Weimerskirch
Variability in demographic traits between individuals within populations has profound implications for both evolutionary processes and population dynamics. Parental effects as a source of non-genetic inheritance are important processes to consider to understand the causes of individual variation. In iteroparous species, parental age is known to influence strongly reproductive success and offspring quality, but consequences on offspring fitness component after independence are much less studied. Based on a 37 years longitudinal monitoring of a long-lived...

Data from: Influence of oxidative homeostasis on bacterial density and cost of infection in Drosophila–Wolbachia symbioses

David Monnin, Natacha Kremer, Clément Berny, Hélène Henri, Adeline Dumet, Yann Voituron, Emmanuel Desouhant, Fabrice Vavre, A. Dumet, Y. Voituron, D. Monnin, N. Kremer, C. Berny, H. Henri, E. Desouhant & F. Vavre
The evolution of symbioses along the continuum between parasitism and mutualism can be influenced by the oxidative homeostasis, i.e. the balance between reactive oxygen species (ROS) and antioxidant molecules. Indeed, ROS can contribute to the host immune defence to regulate symbiont populations, but are also toxic. This interplay between ROS and symbiosis is notably exemplified by recent results in arthropod-Wolbachia interactions. Wolbachia are symbiotic bacteria involved in a wide range of interactions with their arthropods...

Data from: Migratory connectivity and effects of winter temperatures on migratory behaviour of the European robin Erithacus rubecula: a continent-wide analysis

Roberto Ambrosini, José Cuervo, Chris Du Feu, Wolfgang Fiedler, Musitelli Federica, Diego Rubolini, Beatrice Sicurella, Fernando Spina, Nicola Saino, Anders Møller & Federica Musitelli
1. Many partially migratory species show phenotypically divergent populations in terms of migratory behaviour, with climate hypothesized to be a major driver of such variability through its differential effects on sedentary and migratory individuals. 2. Based on long-term (1947–2011) bird ringing data, we analysed phenotypic differentiation of migratory behaviour among populations of the European robin Erithacus rubecula across Europe. 3. We showed that clusters of populations sharing breeding and wintering ranges varied from partial (British...

Data from: Seascape and life-history traits do not predict self-recruitment in a coral reef fish

Marcela Herrera, Gerrit B. Nanninga, Serge Planes, Geoffrey P. Jones, Simon R. Thorrold, Pablo Saenz-Agudelo, Glenn R. Almany & Michael L. Berumen
The persistence and resilience of many coral reef species are dependent on rates of connectivity among sub-populations. However, despite increasing research efforts, the spatial scale of larval dispersal remains unpredictable for most marine metapopulations. Here, we assess patterns of larval dispersal in the angelfish Centropyge bicolor in Kimbe Bay, Papua New Guinea, using parentage and sibling reconstruction analyses based on 23 microsatellite DNA loci. We found that, contrary to previous findings in this system, self-recruitment...

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: Genome scan reveals selection acting on genes linked to stress response in wild pearl millet

Cécile Berthouly-Salazar, Anne-Céline Thuillet, Bénédicte Rhoné, Cédric Mariac, Issaka Salia Ousseini, Marie Couderc, Maud I. Tenaillon & Yves Vigouroux
Uncovering genomic regions involved in adaption is a major goal in evolutionary biology. High-throughput sequencing now makes it possible to tackle this challenge in nonmodel species. Yet, despite the increasing number of methods targeted to specifically detect genomic footprints of selection, the complex demography of natural populations often causes high rates of false positive in gene discoveries. The aim of this study was to identify climate adaptations in wild pearl millet populations, Cenchrus americanus ssp....

Data from: How the truffle got its mate: insights from genetic structure in spontaneous and planted Mediterranean populations of Tuber melanosporum

Elisa Taschen, François Rousset, Mathieu Sauve, Laure Benoit, Marie-Pierre Dubois, Franck Richard, Marc-André Selosse, E. Taschen, M. Sauve, L. Benoit, M.-P. Dubois, F. Richard & M.-A. Selosse
The life cycles and dispersal of edible fungi are still poorly known, thus limiting our understanding of their evolution and domestication. The prized Tuber melanosporum produces fruitbodies (fleshy organs where meiospores mature) gathered in natural, spontaneously inoculated forests or harvested in plantations of nursery-inoculated trees. Yet, how fruitbodies are formed remains unclear, thus limiting yields, and how current domestication attempts affect population genetic structure is overlooked. Fruitbodies result from mating between two haploid individuals: the...

Data from: Relating fitness to long-term environmental variations in natura

Pascal Milesi, Thomas Lenormand, Christophe Lagneau, Mylène Weill & Pierrick Labbé
Quantifying links between ecological processes and adaptation dynamics in natura remains a crucial challenge. Many studies have documented the strength, form and direction of selection, and its variations in space and time, but only a few managed to link these variations to their proximal causes. This step is, however, crucial, if we are to understand how the variation in selective pressure affects adaptive allele dynamics in natural settings. We used data from a long-term survey...

Data from: Distinguishing contemporary hybridization from past introgression with postgenomic ancestry-informative SNPs in strongly differentiated Ciona species

Sarah Bouchemousse, Cathy Liautard-Haag, Nicolas Bierne & Frédérique Viard
Biological introductions bring into contact species that can still hybridize. The evolutionary outcomes of such secondary contacts may be diverse (e.g. adaptive introgression from or into the introduced species) but are not yet well examined in the wild. The recent secondary contact between the non-native sea squirt Ciona robusta (formerly known as C. intestinalis type A) and its native congener C. intestinalis (formerly known as C. intestinalis type B), in the Western English Channel, provides...

Data from: A molecular phylogeny and revised higher-level classification for the leaf-mining moth family Gracillariidae and its implications for larval host-use evolution

Akito Y. Kawahara, David Plotkin, Issei Ohshima, Carlos Lopez-Vaamonde, Peter R. Houlihan, Jesse W. Breinholt, Atsushi Kawakita, Lei Xiao, Jerome C. Regier, Donald R. Davis, Tosio Kumata, Jay-Cheon Sohn, Jurate De Prins, Charles Mitter & JAE-CHEON SOHN
Gracillariidae are one of the most diverse families of internally feeding insects, and many species are economically important. Study of this family has been hampered by lack of a robust and comprehensive phylogeny. In the present paper, we sequenced up to 22 genes in 96 gracillariid species, representing all previously recognized subfamilies and genus groups, plus 20 outgroups representing other families and superfamilies. Following objective identification and removal of two rogue taxa, two datasets were...

Data from: Food supplementation and predation risk in harsh climate: interactive effects on abundance and body condition of tit species

Chiara Morosinotto, Alexandre Villers, Rauno Varjonen & Erkki Korpimäki
Food availability and predation risk can have drastic impacts on animal behaviour and populations. The tradeoff between foraging and predator avoidance is crucial for animal survival and will strongly affect individual body mass, since large fat reserves are beneficial to reduce starvation but may increase predation risk. However, two-factor experiments simultaneously investigating the interactive effects of food and predation risk, are still rare. We studied the effects of food supplementation and natural predation risk imposed...
