Data from: Climate and habitat interacts to shape the thermal reaction norms of breeding phenology across lizard populations

Alexis Rutschmann, Donald B. Miles, Jean-François Le Galliard, Murielle Richard, Sylvain Moulhérat, Barry Sinervo & Jean Clobert
1. Substantial plastic variation in phenology in response to environmental heterogeneity through time in the same population has been uncovered in many species. However, our understanding of differences in reaction norms of phenology among populations from a given species remains limited. 2. Since the plasticity of phenological traits is often influenced by local thermal conditions, we expect local temperature to generate variation in the reaction norms between populations. 3. Here, we explored temporal variation in...

Data from: Within-host stochastic emergence dynamics of immune-escape mutants

Matthew Hartfield & Samuel Alizon
Predicting the emergence of new pathogenic strains is a key goal of evolutionary epidemiology. However, the majority of existing studies have focussed on emergence at the population level, and not within a host. In particular, the coexistence of pre-existing and mutated strains triggers a heightened immune response due to the larger total pathogen population; this feedback can smother mutated strains before they reach an ample size and establish. Here, we extend previous work for measuring...

Data from: Ditch network sustains functional connectivity and influences patterns of gene flow in an intensive agricultural landscape

Lisa Favre-Bac, Cendrine Mony, Aude Ernoult, Françoise Burel & Jean-Francois Arnaud
In intensive agricultural landscapes, plant species previously relying on semi-natural habitats may persist as metapopulations within landscape linear elements. Maintenance of populations’ connectivity through pollen and seed dispersal is a key factor in species persistence in the face of substantial habitat loss. The goals of this study were to investigate the potential corridor role of ditches and to identify the landscape components that significantly impact patterns of gene flow among remnant populations. Using microsatellite loci,...

Data from: Phage selection for bacterial cheats leads to population decline

Marie Vasse, Clara Torres-Barceló & Michael E. Hochberg
While predators and parasites are known for their effects on bacterial population biology, their impact on the dynamics of bacterial social evolution remains largely unclear. Siderophores are iron-chelating molecules that are key to the survival of certain bacterial species in iron-limited environments, but their production can be subject to cheating by non-producing phenotypes. In a selection experiment conducted over c 20 bacterial generations and involving 140 populations of the pathogenic bacterium Pseudomonas aeruginosa PAO1, we...

Data from: Next-generation monitoring of aquatic biodiversity using environmental DNA metabarcoding

Alice Valentini, Pierre Taberlet, Claude Miaud, Raphaël Civade, Jelger Herder, Philip Francis Thomsen, Eva Bellemain, Aurélien Besnard, Eric Coissac, Frédéric Boyer, Coline Gaboriaud, Pauline Jean, Nicolas Poulet, Nicolas Roset, Gordon H. Copp, Philippe Geniez, Didier Pont, Christine Argillier, Jean-Marc Baudoin, Tiphaine Peroux, Alain J. Crivelli, Anthony Olivier, Manon Acqueberge, Matthieu Le Brun, Peter Rask Møller … & Tony Dejean
Global biodiversity in freshwater and the oceans is declining at high rates. Reliable tools for assessing and monitoring aquatic biodiversity, especially for rare and secretive species, are important for efficient and timely management. Recent advances in DNA sequencing have provided a new tool for species detection from DNA present into the environment. In this study, we tested if an environmental DNA (eDNA) metabarcoding approach, using water samples, can be used for addressing significant questions in...

Data from: From steps to home range formation: species-specific movement upscaling among sympatric ungulates

Zulima Tablado, Eloy Revilla, Dominique Dubray, Sonia Saïd, Daniel Maillard & Anne Loison
Animals move to interact with the environment in order to find food resources and cover. Intrinsic characteristics affecting feeding and antipredatory strategies likely shape variation in movement patterns and home range formation between individuals, populations and species. Browsing herbivores selectively forage on patchily distributed resources in areas with more canopy cover, whereas mixed feeders and grazers feed on more open grasslands and tend to aggregate as an antipredatory strategy. We therefore predicted that at small...

Data from: Quantifying age-dependent extinction from species phylogenies

Helen K. Alexander, Amaury Lambert & Tanja Stadler
Several ecological factors that could play into species extinction are expected to correlate with species age, i.e., time elapsed since the species arose by speciation. To date, however, statistical tools to incorporate species age into likelihood-based phylogenetic inference have been lacking. We present here a computational framework to quantify age-dependent extinction through maximum likelihood parameter estimation based on phylogenetic trees, assuming species lifetimes are gamma distributed. Testing on simulated trees shows that neglecting age dependence...

Data from: On the evolutionary interplay between dispersal and local adaptation in heterogeneous environments

Andrew M. Berdahl, Colin J. Torney, Emmanuel Schertzer, Simon A. Levin & Andrew Berdahl
Dispersal, whether in the form of a dandelion seed drifting on the breeze, or a salmon migrating upstream to breed in a non-natal stream, transports genes between locations. At these locations, local adaptation modifies the gene frequencies so their carriers are better suited to particular conditions, be those of newly disturbed soil or a quiet river pool. Both dispersal and local adaptation are major drivers of population structure; however, in general, their respective roles are...

Data from: Seeking signatures of reinforcement at the genetic level: a hitchhiking mapping and candidate gene approach in the house mouse

Carole M. Smadja, Etienne Loire, Pierre Caminade, Marios Thoma, Yasmin Latour, Camille Roux, Michaela Thoss, Dustin J. Penn, Gulia Ganem & Pierre Boursot
Reinforcement is the process by which prezygotic isolation is strengthened as a response to selection against hybridization. Most empirical support for reinforcement comes from the observation of its possible phenotypic signature: an accentuated degree of prezygotic isolation in the hybrid zone as compared to allopatry. Here, we implemented a novel approach to this question by seeking for the signature of reinforcement at the genetic level. In the house mouse, selection against hybrids and enhanced olfactory-based...

Data from: Evolutionary factors affecting the cross-species utility of newly developed microsatellite markers in seabirds

Yoshan Moodley, Juan F. Masello, Gopi K. Munimanda, Theresa L. Cole, Marco R. Thali, Rachael Alderman, Richard J. Cuthbert, Manuel Marin, Melanie Massaro, Joan Navarro, Richard A. Phillips, Peter G. Ryan, Cristián G. Suazo, Yves Cherel, Henri Weimerskirch, Petra Quillfeldt & Luciano Calderon
Microsatellite loci are ideal for testing hypotheses relating to genetic segregation at fine spatio-temporal scales. They are also conserved among closely related species, making them potentially useful for clarifying interspecific relationships between recently diverged taxa. However, mutations at primer binding sites may lead to increased nonamplification, or disruptions that may result in decreased polymorphism in nontarget species. Furthermore, high mutation rates and constraints on allele size may also with evolutionary time, promote an increase in...

Data from: Superinfection and the coevolution of parasite virulence and host recovery

Sarah Kada & Sébastien Lion
Parasite strategies of host exploitation may be affected by host defence strategies and multiple infections. In particular, within-host competition between multiple parasite strains has been shown to select for higher virulence. However, little is known on how multiple infections could affect the coevolution between host recovery and parasite virulence. Here, we extend a coevolutionary model introduced by van Baalen (1998) to account for superinfection. When the susceptibility to superinfection is low, we recover van Baalen's...

Data from: An exceptionally preserved Late Devonian actinopterygian provides a new model for primitive cranial anatomy in ray-finned fishes

Sam Giles, Laurent Darras, Gaël Clément, Alain Blieck & Matt Friedman
Actinopterygians (ray-finned fishes) are the most diverse living osteichthyan (bony vertebrate) group, with a rich fossil record. However, details of their earliest history during the middle Palaeozoic (Devonian) ‘Age of Fishes' remains sketchy. This stems from an uneven understanding of anatomy in early actinopterygians, with a few well-known species dominating perceptions of primitive conditions. Here we present an exceptionally preserved ray-finned fish from the Late Devonian (Middle Frasnian, ca 373 Ma) of Pas-de-Calais, northern France....

Data from: Spatiotemporal spike coding of behavioral adaptation in the dorsal anterior cingulate cortex

Laureline Logiaco, René Quilodran, Emmanuel Procyk & Angelo Arleo
The frontal cortex controls behavioral adaptation in environments governed by complex rules. Many studies have established the relevance of firing rate modulation after informative events signaling whether and how to update the behavioral policy. However, whether the spatiotemporal features of these neuronal activities contribute to encoding imminent behavioral updates remains unclear. We investigated this issue in the dorsal anterior cingulate cortex (dACC) of monkeys while they adapted their behavior based on their memory of feedback...

Data from: Recasting the dynamic equilibrium model through a functional lens: the interplay of trait-based community assembly and climate

Jessy Loranger, Cyrille Violle, Bill Shipley, Sandra Lavorel, Anne Bonis, Pablo Cruz, Frédérique Louault, Grégory Loucougaray, François Mesléard, Nicole Yavercovski & Éric Garnier
1. According to the dynamic equilibrium hypothesis (DEH), plant species richness is locally controlled by productivity and disturbance. Given that regional conditions widely affect local environmental variables such as soil nutrient availability, the DEH predictions could be improved by considering how climate influences local controls of species richness. Further, a trait-based approach to community assembly has the potential to reveal a deeper, mechanistic understanding of species richness variation across environments. Here we bring together DEH...

Data from: Social network structure in wintering golden-crowned sparrows is not correlated with kinship

Nina N. Arnberg, Bruce E. Lyon, Daizaburo Shizuka & Alexis S. Chaine
Stable social organization in a wide variety of organisms has been linked to kinship, which can minimize conflict due to the indirect fitness benefits from cooperating with relatives. In birds, kin selection has been mostly studied in the context of reproduction or in species that are social year round. Many birds however are migratory, and the role of kinship in the winter societies of these species is virtually unexplored. In a previous study, we discovered...

Data from: Social information from immigrants: multiple immigrant based sources of information for dispersal decisions in a ciliate

Staffan Jacob, Alexis S. Chaine, Nicolas Schtickzelle, Michèle Huet & Jean Clobert
1. Dispersal is increasingly recognized as being an informed process, based on information organisms obtain about the landscape. While local conditions are often found to drive dispersal decisions, local context is not always a reliable predictor of conditions in neighbouring patches, making the use of local information potentially useless or even maladaptive. In this case, using social information gathered by immigrants might allow adjusting dispersal decisions without paying the costs of prospecting. However, this hypothesis...

Data from: Extreme ecological response of a seabird community to unprecedented sea ice cover

Christophe Barbraud, Karine Delord & Henri Weimerskirch
Climate change has been predicted to reduce Antarctic sea ice but, instead, sea ice surrounding Antarctica has expanded over the past 30 years, albeit with contrasted regional changes. Here we report a recent extreme event in sea ice conditions in East Antarctica and investigate its consequences on a seabird community. In early 2014, the Dumont d'Urville Sea experienced the highest magnitude sea ice cover (76.8%) event on record (1982–2013: range 11.3–65.3%; mean±95% confidence interval: 27.7%...

Data from: Alternative reproductive tactics in female striped mice: heavier females are more likely to breed solitary than communally

Davina L. Hill, Neville Pillay & Carsten Schradin
1. Alternative reproductive tactics (ARTs) are discrete reproductive phenotypes governed by decision rules called strategies. ARTs are fixed for life in species with alternative strategies, while tactic expression is plastic in species with a single strategy. ARTs have been investigated in males of many species, but few studies have tested whether the same theoretical framework applies in females. 2. Female striped mice (Rhabdomys pumilio) employ three ARTs: communal breeders give birth in a nest shared...

Data from: Spatial heterogeneity in landscape structure influences dispersal and genetic structure: empirical evidence from a grasshopper in an agricultural landscape

Bertrand Gauffre, Sophie Mallez, Marie-Pierre Chapuis, Leblois Raphael, Isabelle Litrico, Sabrina Delaunay, Isabelle Badenhausser & Raphael Leblois
Dispersal may be strongly influenced by landscape and habitat characteristics that could either enhance or restrict movements of organisms. Therefore, spatial heterogeneity in landscape structure could influence gene flow and the spatial structure of populations. In the past decades, agricultural intensification has led to the reduction in grassland surfaces, their fragmentation and intensification. As these changes are not homogeneously distributed in landscapes, they have resulted in spatial heterogeneity with generally less intensified hedged farmland areas...

Data from: Avian malaria: a new lease of life for an old experimental model to study the evolutionary ecology of Plasmodium

Romain Pigeault, Julien Vézilier, Stéphane Cornet, Flore Zélé, Antoine Nicot, Philippe Perret, Sylvain Gandon & Ana Rivero
Avian malaria has historically played an important role as a model in the study of human malaria, being a stimulus for the development of medical parasitology. Avian malaria has recently come back to the research scene as a unique animal model to understand the ecology and evolution of the disease, both in the field and in the laboratory. Avian malaria is highly prevalent in birds and mosquitoes around the world and is amenable to laboratory...

Data from: Dearth of polymorphism associated with a sustained response to selection for flowering time in maize

Eleonore Durand, Maud I. Tenaillon, Xavier Raffoux, Stéphanie Thépot, Matthieu Falque, Philippe Jamin, Aurélie Bourgais, Adrienne Ressayre & Christine Dillmann
Background: Long term selection experiments bring unique insights on the genetic architecture of quantitative traits and their evolvability. Indeed, they are utilized to (i) monitor changes in allele frequencies and assess the effects of genomic regions involved traits determinism; (ii) evaluate the role of standing variation versus new mutations during adaptation; (iii) investigate the contribution of non allelic interactions. Here we describe genetic and phenotypic evolution of two independent Divergent Selection Experiments (DSEs) for flowering...

Data from: Morphological drivers of trophic cascades

Clémentine Renneville, Arnaud Le Rouzic, Michel Baylac, Alexis Millot, Stéphane Loisel & Eric Edeline
Worldwide, local anthropogenic extinctions have recently been reported to induce trophic cascades, defined as perturbations of top consumers that propagate along food chains down to primary producers. This focus on the effects of top-consumer extinction (i.e. of species presence) ignores potential cascading effects of the rapid morphological changes that may precede extinction. Here, we show in an experimental, three-level food chain including medaka fish, herbivorous zooplankton and unicellular algae that varying body length of a...

Data from: Relationships between invasion success and colony breeding structure in a subterranean termite

Elfie Perdereau, Anne-Geneviève Bagnères, Edward L. Vargo, Guillaume Baudouin, Yijuan Xu, Paul Labadie, Simon Dupont & Franck Dedeine
Factors promoting the establishment and colonization success of introduced populations in new environments constitute an important issue in biological invasions. In this context, the respective role of pre-adaptation and evolutionary changes during the invasion process is a key question that requires particular attention. This study compared the colony breeding structure (i.e. number and relatedness among reproductives within colonies) in native and introduced populations of the subterranean pest termite, Reticulitermes flavipes. We generated and analysed a...

Data from: High chlorpyrifos resistance in Culex pipiens mosquitoes: strong synergy between resistance genes

Pierrick Labbé, Haoues Alout, Arnaud Berthomieu, Patrick Makoundou, Nicole Pasteur, Mylene Weill & Philippe Fort
We investigated the genetic determinism of high chlorpyrifos resistance (HCR), a phenotype first described in 1999 in Culex pipiens mosquitoes surviving chlorpyrifos doses greater than or equal to1 mg l−1 and more recently found in field samples from Tunisia, Israel or Indian Ocean islands. Through chlorpyrifos selection, we selected several HCR strains that displayed over 10 000-fold resistance. All strains were homozygous for resistant alleles at two main loci: the ace-1 gene, with the resistant...

Data from: Range-wide population structure of European sea bass Dicentrarchus labrax

Erika L. Souche, Bart Hellemans, Massimiliano Babbucci, Eoin MacAoidh, Bruno Guinand, Luca Bargelloni, Dimitry Alexandrovich Chistiakov, Tomaso Patarnello, François Bonhomme, Jann T. Martinsohn & Filip A. M. Volckaert
The euryhaline European sea bass Dicentrarchus labrax L., inhabiting the coasts of the eastern Atlantic Ocean and Mediterranean Sea, has had many opportunities for differentiation throughout its large natural range. However, evidence for this has been incompletely documented geographically and with an insufficient number of markers. Therefore, its full range was sampled at 22 sites and individuals were genotyped with a suite of mapped markers, including 14 microsatellite loci (N = 536) and 46 neutral...
