Data and code from: Phenotypic memory drives population growth and extinction risk in a noisy environment

Marie Rescan, Daphné Grulois, Enrique Ortega-Aboud & Luis-Miguel Chevin
Random environmental fluctuations pose major threats to wild populations. As patterns of environmental noise are themselves altered by global change, there is growing need to identify general mechanisms underlying their effects on population dynamics. This notably requires understanding and predicting population responses to the color of environmental noise, i.e. its temporal autocorrelation pattern. Here, we show experimentally that environmental autocorrelation has a large influence on population dynamics and extinction rates, which can be predicted accurately...

Genetic evidence further elucidates the history and extent of badger introductions from Great Britain into Ireland

Adrian Allen, Jimena Guerrero, Andrew Byrne, John Lavery, Eleanor Presho, Emily Courcier, James O'Keeffe, Ursula Fogarty, Richard Delahay, Gavin Wilson, Chris Newman, Christina Buesching, Matthew Silk, Denise O'Meara, Robin Skuce, Roman Biek & Robbie A. McDonald
The colonization of Ireland by mammals, has been the subject of extensive study using genetic methods, and forms a central problem in understanding the phylo-geography of European mammals after the Last Glacial Maximum. Ireland exhibits a de-pauperate mammal fauna relative to Great Britain and continental Europe, and a range of natural and anthropogenic processes have given rise to its modern fauna. Previous Europe-wide surveys of the European badger (Meles meles) have found conflicting microsatellite and...

Hybridization and transgressive exploration of colour pattern and wing morphology in Heliconius butterflies

Claire Mérot, Vincent Debat, Yann Le Poul, Richard M Merrill, Russell E Naisbit, Adélie Tholance, Chris Jiggins & Mathieu Joron
Hybridization can generate novel phenotypes distinct from those of parental lineages, a phenomenon known as transgressive trait variation. Transgressive phenotypes might negatively or positively affect hybrid fitness, and increase available variation. Closely related species of Heliconius butterflies regularly produce hybrids in nature and hybridization is thought to play a role in the diversification of novel wing colour patterns despite strong stabilizing selection due to interspecific mimicry. Here, we studied wing phenotypes in first and second...

Raw acceleration, gyroscope and depth profiles associated with the observed behaviours of free-ranging immature green turtles in Martinique

Lorene Jeantet, Victor Planas-Bielsa, Simon Benhamou, Sébastien Geiger, Jordan Martin, Flora Siegwalt, Pierre Lelong, Julie Gresser, Denis Etienne, Gaëlle Hiélard, Alexandre Arque, Sidney Regis, Nicolas Lecerf, Cédric Frouin, Abdelwahab Benhalilou, Céline Murgale, Thomas Maillet, Lucas Andreani, Guilhem Campistron, Hélène Delvaux, Christelle Guyon, Sandrine Richard, Fabien Lefebvre, Nathalie Aubert, Caroline Habold … & Damien Chevallier
The identification of sea turtle behaviours is a prerequisite to predicting the activities and time-budget of these animals in their natural habitat over long term. However, this is hampered by a lack of reliable methods that enable the detection and monitoring of certain key behaviours such as feeding. This study proposes a combined approach that automatically identifies the different behaviours of free-ranging sea turtles through the use of animal-borne multi-sensor recorders (accelerometer, gyroscope and time-depth...

Data from: Ecology shapes epistasis in a genotype-phenotype-fitness map for stick insect colour

Zachariah Gompert, Patrik Nosil, Romain Villoutreix, Clarissa De Carvalho, Jeffrey Feder & Thomas Parchman
Genetic interactions such as epistasis are widespread in nature and can shape evolutionary dynamics. Epistasis occurs due to non-linearity in biological systems, which can arise via cellular processes that convert genotype to phenotype and via selective processes that connect phenotype to fitness. Few studies in nature have connected genotype to phenotype to fitness for multiple potentially interacting genetic variants. Thus, the causes of epistasis in the wild remain poorly understood. Here, we show that epistasis...

Data from: Large-scale mutation in the evolution of a gene complex for cryptic coloration

Zachariah Gompert, Romain Villoutreix, Clarissa De Carvalho, Victor Soria-Carrasco, Dorothea Lindtke, Marisol De-La-Mora, Moritz Muschick, Jeffrey Feder, Thomas Parchman & Patrik Nosil
The types of mutations affecting adaptation in the wild are only beginning to be understood. In particular, whether structural changes shape adaptation by suppressing recombination or by creating new mutations is unresolved. Here we show that multiple, linked but recombining loci underlie cryptic color morphs of Timema chumash stick insects. In a related species, these loci are found in a region of suppressed recombination, forming a supergene. However, in seven species of Timema we find...

Exploring intraspecific variation in migratory destinations to investigate the drivers of migration

Anne-Sophie Bonnet-Lebrun, Marius Somveille, Ana S.L. Rodrigues & Andrea Manica
Various benefits (e.g. tracking of resources and of climate niche) and costs (e.g. distance travelled) are hypothesized to drive seasonal animal migrations. Until now, these potential factors have been investigated together at the species level, but migratory movements are made at the individual level, leading to intraspecific variability. Here, we use ringing/recovery data from 1308 individuals belonging to thirteen North American bird species to analyse patterns in intraspecific variability of migratory destinations in order to...

Data from: Evaluating the link between predation and pest control services in the mite world

Lise Roy, Adrien Taudière & Olivier Bonato
Pest regulation by natural enemies has a strong potential to reduce the use of synthetic pesticides in agroecosystems. However, the effective role of predation as an ecosystem service remains largely speculative, especially with minute organisms such as mites. Predatory mites are natural enemies for ectoparasites in livestock farms. We tested for an ecosystem-level control of the poultry pest Dermanyssus gallinae by other mites naturally present in manure in poultry farms, and investigated differences among farming...

Configurational crop heterogeneity increases within-field plant diversity

Audrey Alignier, Xavier Solé-Senan, Irene Robleño, Barbara Baraibar, Fahrig Lenore, David Giralt, Nicolas Gross, Jean-Louis Martin, Jordi Recasens, Clelia Sirami, Gavin Siriwardena, Aliette Bosem Baillod, Colette Bertrand, Romain Carrie, Annika Hass, Laura Henckel, Paul Miguet, Isabelle Badenhausser, Jacques Baudry, Gerard Bota, Vincent Bretagnolle, Lluis Brotons, Francoise Burel, François Calatayud, Yann Clough … & Péter Batáry
1. Increasing landscape heterogeneity by restoring semi-natural elements to reverse farmland biodiversity declines is not always economically feasible or acceptable to farmers due to competition for land. We hypothesized that increasing the heterogeneity of the crop mosaic itself, hereafter referred to as crop heterogeneity, can have beneficial effects on within-field plant diversity. 2. Using a unique multi-country dataset from a cross-continent collaborative project covering 1451 agricultural fields within 432 landscapes in Europe and Canada, we...

Data from: Demographic history and genomic diversity and divergence in blue tit populations across heterogeneous environments

Charles Perrier, Quentin Rougemont & Anne Charmantier
Understanding the genomic processes underlying local adaptation is a central aim of modern evolutionary biology. This task requires identifying footprints of local selection but also estimating spatio-temporal variation in population demography and variation in recombination rate and diversity along the genome. Here, we investigated these parameters in blue tit populations inhabiting deciduous versus evergreen forests and insular versus mainland areas, in the context of a previously described strong phenotypic differentiation. Neighboring population pairs of deciduous...

Data from : Vacant yet invasible niches in forest community assembly

Pierre Gauzere, Xavier Morin, Cyrille Violle, Ivanna Caspeta, Courtenay Ray & Benjamin Blonder
It is controversial whether communities are saturated with species, or have vacant niches. The prevalence of vacant niches and the processes likely to promote their existence are poorly known. We used a process‐based forest gap‐model to simulate plant community dynamics in 11 sites along a climatic gradient across central Europe. We then used hypervolume analyses to study the existence of vacant niches (seen as empty volumes in the trait space of local species pools and...

Data from: How to make methodological decisions when inferring social networks

André Ferreira, Rita Covas, Liliana Silva, Sandra Esteves, Inês Duarte, Rita Fortuna, Franck Theron, Claire Doutrelant & Damien Farine
Social network analyses allow studying the processes underlying the associations between individuals and the consequences of those associations. Constructing and analysing social networks can be challenging, especially when designing new studies as researchers are confronted with decisions about how to collect data and construct networks, and the answers are not always straightforward. The current lack of guidance on building a social network for a new study system might lead researchers to try several different methods,...

Data from: Recent biological invasion shapes species recognition and aggressive behavior in a native species: a behavioral experiment using robots in the field

Claire Dufour, David Clark, Jonathan Losos & Anthony Herrel
Invasive species are a worldwide threat to biodiversity. Yet, our understanding of biological invasions remains incomplete, partly due to the difficulty of tracking and studying behavioral interactions in recently created species interactions. We tested whether the interactions between the recently introduced invasive lizard Anolis cristatellus and the native Anolis oculatus in Dominica have led to changes in species recognition and aggressive behavior of the native species. The use of realistic robots allowed us to test...

Examining the link between relaxed predation and bird colouration on islands

Louis Bliard, Matthieu Paquet, Aloïs Robert, Paul Dufour, Julien Renoult, Arnaud Gregoire, Pierre-Andre Crochet, Rita Covas & Claire Doutrelant
Insular ecosystems share analogous ecological conditions, leading to patterns of convergent evolution that are collectively termed the “island syndrome”. In birds, part of this syndrome is a tendency for a duller plumage, possibly as a result of relaxed sexual selection and the reduced need for species recognition. Despite this global pattern, some insular species display a more colourful plumage than their mainland relatives, but why this occurs has remained unexplained. Here, we examine the hypothesis...

Generalist plants are more competitive and more functionally similar to each other than specialist plants: insights from network analyses

Pierre Denelle, Cyrille Violle & François Munoz
Aim: Ecological specialization is a property of species associated with the variety of contexts they occupy. Identifying the mechanisms influencing specialization is critical to understand species coexistence and biodiversity patterns. However, the functional attributes leading to specialization are still unknown. Similarly, there is contrasting evidence between the level of specialization and local abundance of species. We ask whether plant specialist and generalist species (i) are associated with distinct functional profiles, using core plant functional traits...

Data from: Floral trait differentiation in Anacamptis coriophora: phenotypic selection on scents, but not on colour

Nina Joffard, Iris Le Roncé, Alban Langlois, Julien Renoult, Bruno Buatois, Laurent Dormont & Bertrand Schatz
Current divergent selection may promote floral trait differentiation among conspecific populations in flowering plants. However, whether this applies to complex traits such as colour or scents has been little studied, even though these traits often vary within species. In this study, we compared floral colour and odour as well as selective pressures imposed upon these traits among seven populations belonging to three subspecies of the widespread, generalist orchid Anacamptis coriophora. Colour was characterised using calibrated...

Data from: Understanding the social dynamics of breeding phenology: indirect genetic effects and assortative mating in a long distance migrant

Maria Moiron, Yimen G. Araya-Ajoy, Céline Teplitsky, Sandra Bouwhuis & Anne Charmantier
Phenological traits, such as the timing of reproduction, are often influenced by social interactions between paired individuals. Such partner effects may occur when pair members affect each other’s pre-breeding environment. Partner effects can be environmentally and/or genetically determined, and quantifying direct and indirect genetic effects is important for understanding the evolutionary dynamics of phenological traits. Here, using 26 years of data from a pedigreed population of a migratory seabird, the common tern ( Sterna hirundo...

Increased microclimatic variation in artificial nests does not create ecological traps for a secondary cavity breeder, the European roller

Timothée Schwartz, Arnaud Genouville & Aurélien Besnard
Artificial devices are increasingly used in conservation measures to mitigate the disappearance of natural habitats. However, few studies have demonstrated their benefits for the target species, and they may pose a risk of creating ecological traps. This occurs when lower individual fitness is found in artificial habitats that are more attractive than their natural equivalents. In this study, we tested the ecological trap hypothesis on a dense population of European rollers Coracias garrulus breeding in...

Dataset for METAPOPGEN 2.0: a multi-locus genetic simulator to model populations of large size

Marco Andrello, Christelle Noirot, Florence Débarre & Stéphanie Manel
Multi-locus genetic processes in subdivided populations can be complex and difficult to interpret using theoretical population genetics models. Genetic simulators offer a valid alternative to study multi-locus genetic processes in arbitrarily complex scenarios. However, the use of forward-in-time simulators in realistic scenarios involving high numbers of individuals distributed in multiple local populations is limited by computation time and memory requirements. These limitations increase with the number of simulated individuals. We developed a genetic simulator, MetaPopGen...

Relative effects of climate and litter traits on decomposition change with time, climate and trait variability

Rafaella Canessa, Liesbeth Van Den Brink, Alfredo Saldana, Rodrigo Rios, Stephan Hattenschwiler, Carsten Mueller, Isabel Prater, Katja Tielboerger & Maaike Bader
Climate and litter quality drive litter decomposition, but there is currently little consensus on their relative importance, likely because studies differ in the duration, the climatic gradients, and variability in litter-trait values. Understanding these drivers is important because they determine the direct and indirect (via vegetation composition) effects of climate change on decomposition and thereby on carbon and nutrient cycling. We studied how microclimate (soil moisture and temperature) and litter traits interactively affect litter mass...

On the evolutionary epidemiology of SARS-CoV-2

Troy Day, Sylvain Gandon, Sébastien Lion & Sarah P. Otto
There is no doubt that the novel coronavirus SARS-CoV-2 that causes COVID-19 is mutating and thus has the potential to adapt during the current pandemic. Whether this evolution will lead to changes in the transmission, the duration, or the severity of the disease is not clear. This has led to considerable scientific and media debate, from raising alarms about evolutionary change to dismissing it. Here we review what little is currently known about the evolution...

Mite counts from manure samples

Lise Roy, Olivier Bonato & Jean-Yves Barnagaud
Pest regulation by natural enemies has a strong potential to reduce the use of synthetic pesticides in agroecosystems. However, the effective role of predation as an ecosystem service remains largely speculative, especially with minute organisms such as mites Predatory mites are natural enemies for ectoparasites in livestock farms. We tested for an ecosystem-level control of the poultry pest Dermanyssus gallinae by other mites naturally present in manure in poultry farms, and investigated differences among farming...

Data from: How do predators generalize warning signals in simple and complex prey communities? Insights from a videogame

Monica Arias, John W. Davey, Simon Martin, Chris Jiggins, Nicola Nadeau, Mathieu Joron & Violaine Llaurens
The persistence of distinct warning signals within and between sympatric mimetic communities is a puzzling evolutionary question because selection favours convergence of colour patterns among toxic species. Such convergence is partly shaped by predators’ reaction to similar but not identical stimulus, i.e. generalization behaviour. And generalisation by predators is likely to be shaped by the diversity of local prey. However, studying generalization behaviour is generally limited to simple variations of prey colour patterns. Here, we...

Foraging niche shift maintains breeding parameters of a colonial waterbird during range expansion

Charlotte Francesiaz, Arnaud Béchet, Aurélien Besnard, Nicolas Sadoul, Thomas Blanchon & Elizabeth Yohannes
Relating the effects of foraging niche variation to reproductive dynamics is critical to understand species response to environmental change. We examined foraging niche variations of the slender-billed gull (Chroicocephalus genei), a nomadic colonial waterbird species during its range expansion along the French Mediterranean coast over a 16 year period (1998-2013). We investigated whether range expansion was associated to a change in chick diet, breeding success and chicks body condition. We also examined whether breeding success...
