Data from: Habitat-related variation in the plasticity of a UV sensitive photoreceptor over a small spatial scale in the palmate newt

Jean Secondi, Mélissa Martin, Delphine Goven, Pascal Mège, Stéphane Sourice & Marc Théry
Plastic phenotypes are expected to be favoured in heterogeneous environments compared with stable environments. Sensory systems are interesting to test this theory because they are costly to produce and support, and strong fitness costs are expected if they are not tuned to the local environment. Consistently, the visual system of several species changes with the conditions experienced during early development. However, there is little information on whether the amplitude of the change, i.e. the reaction...

Data from: Empirical phylogenies and species abundance distributions are consistent with pre-equilibrium dynamics of neutral community models with gene flow

Anne-Sophie Bonnet-Lebrun, Andrea Manica, Anders Eriksson, Ana S.L. Rodrigues & Ana S. L. Rodrigues
Community characteristics reflect past ecological and evolutionary dynamics. Here, we investigate whether it is possible to obtain realistically shaped modelled communities – i.e., with phylogenetic trees and species abundance distributions shaped similarly to typical empirical bird and mammal communities – from neutral community models. To test the effect of gene flow, we contrasted two spatially explicit individual-based neutral models: one with protracted speciation, delayed by gene flow, and one with point mutation speciation, unaffected by...

Data from: Pulsed food resources, but not forest cover, determines lifetime reproductive success in a forest-dwelling rodent

Katrine S. Hoset, Alexandre Villers, Ralf Wistbacka & Vesa Selonen
1. The relative contributions of habitat and food availability on fitness may provide evidence for key habitat features needed to safeguard population persistence. However, defining habitat quality for a species can be a complex task, especially if knowledge on the relationship between individual performance and habitat quality is lacking. 2. Here, we determined the relative importance of availability of suitable forest habitat, body mass, and food from masting tree species on female lifetime reproductive success...

Data from: Boldness predicts an individual's position along an exploration-exploitation foraging trade-off

Samantha C. Patrick, David Pinaud & Henri Weimerskirch
Individuals do not have complete information about the environment and therefore they face a trade-off between gathering information (exploration) and gathering resources (exploitation). Studies have shown individual differences in components of this trade-off but how stable these strategies are in a population and the intrinsic drivers of these differences is not well understood. Top marine predators are expected to experience a particularly strong trade-off as many species have large foraging ranges and their prey often...

Data from: Population differentiation or species formation across the Indian and the Pacific Oceans? An example from the brooding marine hydrozoan Macrorhynchia phoenicea

Bautisse Postaire, Pauline Gélin, J. Henrich Bruggemann, Marine Pratlong & Helene Magalon
Assessing population connectivity is necessary to construct effective marine protected areas. This connectivity depends, among other parameters, inherently on species dispersal capacities. Isolation by distance (IBD) is one of the main modes of differentiation in marine species, above all in species presenting low dispersal abilities. This study reports the genetic structuring in the tropical hydrozoan Macrorhynchia phoenicea α (sensu Postaire et al., 2016a), a brooding species, from 30 sampling sites in the Western Indian Ocean...

Data from: Markov-modulated Poisson processes as a new framework for analyzing capture-recapture data

Rémi Choquet
1.Opportunistic capture-recapture data consists of observations over non-constant time-intervals and so fails to satisfy the basic assumptions of traditional capture-recapture models. Analyzing opportunistic capture-recapture data is often done by discretizing time-intervals or summarizing data, but without taking into account the continuous-time process of the state and/or the capture. 2.To deal with non-constant time-intervals, continuous-time closed capture-recapture models have been proposed by Yip et al. (1996), Hwang & Chao (2002), Schofield et al. (2017) for estimating...

Data from: Chaos and the (un)predictability of evolution in a changing environment

Artur Rego Costa, Florence Débarre, Luis-Miguel Chevin & Artur Rego-Costa
Among the factors that may reduce the predictability of evolution, chaos, characterized by a strong dependence on initial conditions, has received much less attention than randomness due to genetic drift or environmental stochasticity. It was recently shown that chaos in phenotypic evolution arises commonly under frequency-dependent selection caused by competitive interactions mediated by many traits. This result has been used to argue that chaos should often make evolutionary dynamics unpredictable. However, populations also evolve largely...

Data from: Resource composition mediates the effects of intraspecific variability in nutrient recycling on ecosystem processes

Charlotte Evangelista, Antoine Lecerf, J. Robert Britton & Julien Cucherousset
Despite the growing evidence for individual variation in trophic niche within populations, its potential indirect effects on ecosystem processes remains poorly understood. In particular, few studies have investigated how intraspecific trophic variability can modulate the effects of consumers on ecosystems through potential changes in nutrient excretion rates. Here, we first quantified the level of intraspecific trophic variability in 11 wild populations of the omnivorous fish Lepomis gibbosus. Outputs from stomach content and stable isotope analyses...

Data from: Asexual queen succession mediates an accelerated colony life cycle in the termite Silvestritermes minutus

Romain Fougeyrollas, Jan Křivánek, Virginie Roy, Klára Dolejšová, Sophie Frechault, Yves Roisin, Robert Hanus & David Sillam-Dussès
Mixed modes of reproduction, combining sexual processes with thelytokous parthenogenesis, occur in all major clades of social insects. In several species of termites, queens maximize their genetic input into nondispersing replacement queens through parthenogenesis, while maintaining genetically diverse sterile offspring and dispersing reproductives via sexual reproduction. This so-called asexual queen succession (AQS) has multiple independent origins and its presumed advantages are diverse as well, ranging from multiplication of colony reproductive potential to extension of its...

Data from: The double edged sword: the demographic consequences of the evolution of self-fertilisation

Diala Abu Awad & Sylvain Billiard
Phylogenies indicate that the transition from outcrossing to selfing is frequent, with selfing populations being more prone to extinction. The rates of transition to selfing and extinction, acting on different timescales, could explain the observed distributions of extant selfing species among taxa. However, phylogenetic and theoretical studies consider these mechanisms independently, i.e. transitions do not cause extinction. Here, we theoretically explore the demographic consequences of the evolution of self-fertilization. Deleterious mutations and mutations modifying the...

Data from: Landscape features impact connectivity between soil populations: a comparative study of gene flow in earthworms

Lise Dupont, Magally Torres-Leguizamon, Peggy René-Corail & Jérôme Mathieu
Landscape features are known to alter the spatial genetic variation of aboveground organisms. Here, we tested the hypothesis that the genetic structure of belowground organisms also responds to landscape structure. Microsatellite markers were used to carry out a landscape genetic study of two endogeic earthworm species, Allolobophora chlorotica (N = 440, eight microsatellites) and Aporrectodea icterica (N = 519, seven microsatellites), in an agricultural landscape in the North of France, where landscape features were characterized...

Data from: Evidence for a genetic sex determination in Cnidaria, the Mediterranean red coral (Corallium rubrum)

Marine Pratlong, Anne Haguenauer, Sandrine Chenesseau, Kelly Brener, Guillaume Mitta, Eve Toulza, M. Bonabaud, S. Rialle, Didier Aurelle & Pierre Pontarotti
Sexual reproduction is widespread among eukaryotes, and the sex-determining processes vary greatly among species. While genetic sex determination (GSD) has been intensively described in bilaterian species, no example has yet been recorded among non-bilaterians. However, the quasi-ubiquitous repartition of GSD among multicellular species suggests that similar evolutionary forces can promote this system, and that these forces could occur also in non-bilaterians. Studying sex determination across the range of Metazoan diversity is indeed important to understand...

Data from: Combining noninvasive genetics and a new mammalian sex-linked marker provides new tools to investigate population size, structure and individual behaviour: an application to bats

Diane Zarzoso-Lacoste, Pierre-Loup Jan, Lisa Lehnen, Thomas Girard, Anne-Laure Besnard, Sebastien J. Puechmaille & Eric J. Petit
Monitoring wild populations is crucial for their effective management. Noninvasive genetic methods provide robust data from individual free-ranging animals, which can be used in capture-mark-recapture (CMR) models to estimate demographic parameters without capturing or disturbing them. However, sex- and status-specific behaviour, which may lead to differences in detection probabilities, is rarely considered in monitoring. Here, we investigated population size, sex ratio, sex- and status-related behaviour in 19 Rhinolophus hipposideros maternity colonies (Northern France) with a...

Data from: The functional syndrome: linking individual trait variability to ecosystem functioning

Allan Raffard, Antoine Lecerf, Julien Cote, Mathieu Buoro, Remy Lassus & Julien Cucherousset
Phenotypic variability is increasingly assessed through functional response and effect traits, which provide a mechanistic framework for investigating how an organism responds to varying ecological factors and how these responses affect ecosystem functioning. Covariation between response and effect traits has been poorly examined at the intraspecific level, thus hampering progress in understanding how phenotypic variability alters the role of organisms in ecosystems. Using a multi-trait approach and a nine-month longitudinal monitoring of individual red-swamp crayfish...

Data from: Booming far: the long-range vocal strategy of a lekking bird

Clément Cornec, Yves Hingrat, Thierry Aubin & Fanny Rybak
The pressures of selection acting on transmission of information by acoustic signals are particularly high in long-distance communication networks. Males of the North African houbara bustard (Chlamydotis undulata undulata) produce extremely low-frequency vocalizations called 'booms' as a component of their courtship displays. These displays are performed on sites separated by a distance of on average 550 m, constituting exploded leks. Here, we investigate the acoustic features of booms involved in species-specific identity. We first assessed...

Data from: Landscape genetic analyses reveal fine-scale effects of forest fragmentation in an insular tropical bird

Aurélie Khimoun, William Peterman, Cyril Eraud, Bruno Faivre, Nicolas Navarro & Stéphane Garnier
Within the framework of landscape genetics, resistance surface modelling is particularly relevant to explicitly test competing hypotheses about landscape effects on gene flow. To investigate how fragmentation of tropical forest affects population connectivity in a forest specialist bird species, we optimized resistance surfaces without a priori specification, using least-cost (LCP) or resistance (IBR) distances. We implemented a two-step procedure in order (i) to objectively define the landscape thematic resolution (level of detail in classification scheme...

Data from: A test of the hierarchical model of litter decomposition

Mark A. Bradford, G. F. Veen, Anne Bonis, Ella M. Bradford, Aimee T. Classen, J. Hans C. Cornelissen, Thomas W. Crowther, Jonathan R. De Long, Gregoire T. Freschet, Paul Kardol, Marta Manrubia-Freixa, Daniel S. Maynard, Gregory S. Newman, Richard S. P. Van Logtestijn, Maria Viketoft, David A. Wardle, William R. Wieder, Stephen A. Wood & Wim H. Van Der Putten
Our basic understanding of plant litter decomposition informs the assumptions underlying widely applied soil biogeochemical models, including those embedded in Earth system models. Confidence in projected carbon cycle-climate feedbacks therefore depends on accurate knowledge about the controls regulating the rate at which plant biomass is decomposed into products such as CO2. Here, we test underlying assumptions of the dominant conceptual model of litter decomposition. The model posits that a primary control on the rate of...

Data from: The effects of climate change on a mega-diverse country: predicted shifts in mammalian species richness and turnover in continental Ecuador.

Paula Iturralde-Pólit, Olivier Dangles, Santiago F. Burneo & Christine N. Meynard
Ecuador is one of 17 nations with the greatest diversity in the world, sheltering lowland and mountain regions that are considered global biodiversity hotspots. While these regions are projected to be highly impacted by climate change, it is not clear what would be the consequences for faunal diversity and conservation. To address this issue, we used an ensemble of 8 species distribution models (SDM) to determine future shifts and identify areas of high changes in...

Data from: The relationship between plumage colouration, problem-solving and learning performance in great tits Parus major

Laure Cauchard, Stéphanie M. Doucet, Neeltje J. Boogert, Bernard Angers & Blandine Doligez
Recent studies suggest that individuals with better problem-solving and/or learning performance have greater reproductive success, and that individuals may thus benefit from choosing mates based on these performances. However, directly assessing these performances in candidate mates could be difficult. Instead, the use of indirect cues related to problem-solving and/or learning performance, such as condition-dependent phenotypic traits, might be favored. We investigated whether problem-solving and learning performance on a novel non-foraging task correlated with sexually selected...

Data from: Unravelling the immune signature of Plasmodium falciparum transmission-reducing immunity

Will J. R. Stone, Joseph J. Campo, André Lin Ouédraogo, Lisette Meerstein-Kessel, Isabelle Morlais, Dari Da, Anna Cohuet, Sandrine Nsango, Colin J. Sutherland, Marga Van De Vegte-Bolmer, Rianne Siebelink-Stoter, Geert-Jan Van Gemert, Wouter Graumans, Kjerstin Lanke, Adam D. Shandling, Jozelyn V. Pablo, Andy A. Teng, Sophie Jones, Roos M. De Jong, Amanda Fabra-García, John Bradley, Will Roeffen, Edwin Lasonder, Giuliana Gremo, Evelin Schwarzer … & Matthijs M. Jore
Infection with Plasmodium can elicit antibodies that inhibit parasite survival in the mosquito, when they are ingested in an infectious blood meal. Here, we determine the transmission-reducing activity (TRA) of naturally acquired antibodies from 648 malaria-exposed individuals using lab-based mosquito-feeding assays. Transmission inhibition is significantly associated with antibody responses to Pfs48/45, Pfs230, and to 43 novel gametocyte proteins assessed by protein microarray. In field-based mosquito-feeding assays the likelihood and rate of mosquito infection are significantly...

Data from: Higher iridescent-to-pigment optical effect in flowers facilitates learning, memory and generalization in foraging bumblebees

Géraud De Premorel, Martin Giurfa, Christine Andraud & Doris Gomez
Iridescence—change of colour with changes in the angle of viewor of illumination— is widespread in the living world but its functions remain poorly understood. The presence of iridescence has been suggested in flowers where diffraction gratings generate iridescent colours. Such colours have been suggested to serve plant–pollinator communication. Here we tested whether a higher iridescence relative to corolla pigmentation would facilitate discrimination, learning and retention of iridescent visual targets. We conditioned bumblebees (Bombus terrestris) to...

Data from: Phylogenetically informed spatial planning is required to conserve the mammalian tree of life

Dan F. Rosauer, Laura J. Pollock, Simon Linke & Walter Jetz
In the face of the current extinction crisis and severely limited conservation resources, safeguarding the tree of life is increasingly recognized as a high priority. We conducted a first systematic global assessment of the conservation of phylogenetic diversity (PD) that uses realistic area targets and highlights the key areas for conservation of the mammalian tree of life. Our approach offers a substantially more effective conservation solution than one focused on species. In many locations, priorities...

Data from: An assessment of phylogenetic tools for analyzing the interplay between interspecific interactions and phenotypic evolution

Jonathan P. Drury, Gregory F. Grether, , Hélène Morlon & T Garland
Much ecological and evolutionary theory predicts that interspecific interactions often drive phenotypic diversification and that species phenotypes in turn influence species interactions. Several phylogenetic comparative methods have been developed to assess the importance of such processes in nature; however, the statistical properties of these methods have gone largely untested. Focusing mainly on scenarios of competition between closely-related species, we assess the performance of available comparative approaches for analyzing the interplay between interspecific interactions and species...

Data from: Nest signature changes throughout colony cycle and after social parasite invasion in social wasps

Marta Elia, Giuliano Blancato, Laura Picchi, Christophe Lucas, Anne-Genevieve Bagneres & Maria Cristina Lorenzi
Social insects recognize their nestmates by means of a cuticular hydrocarbon signature shared by colony members, but how nest signature changes across time has been rarely tested in longitudinal studies and in the field. In social wasps, the chemical signature is also deposited on the nest surface, where it is used by newly emerged wasps as a reference to learn their colony odor. Here, we investigate the temporal variations of the chemical signature that wasps...

Data from: Spontaneous nongenetic variation of group size creates cheater-free groups of social microbes

Michaela Amherd, Gregory J. Velicer & Olaya Rendueles
In social organisms, cheaters that gain a fitness advantage by defecting from the costs of cooperation reduce the average level of cooperation in a population. Such “cheating load” can be severe enough to cause local extinction events when cooperation is necessary for survival, but can also mediate group-level selection against cheaters across spatially structured groups that vary in cheater frequency. In cheater-laden populations, such variation could be generated by the formation of new homogeneous groups...
