Data from: An integrated assessment model of seabird population dynamics: can individual heterogeneity in susceptibility to fishing explain abundance trends in Crozet wandering albatross?

Geoffrey N. Tuck, Robin B. Thomson, Christophe Barbraud, Karine Delord, Maite Louzao, Miguel Herrera & Henri Weimerskirch
1. Seabirds have been incidentally caught in distant-water longline fleets operating in the Southern Ocean since at least the 1970s, and breeding numbers for some populations have shown marked trends of decline and recovery concomitant with longline fishing effort within their distributions. However, lacking is an understanding of how forms of among-individual heterogeneity may interact with fisheries bycatch and influence population dynamics. 2. We develop a model that uses comprehensive data on the spatial and...

Data from: Varroa destructor changes cuticular hydrocarbons to mimic its new host.

Zachary Y. Huang, Yves Le Conte, Jean-Philippe Christidès, Zhi Jiang Zeng, Maurice Roux & Anne-Genevieve Bagnères
Varroa destructor (Vd) is a honeybee ectoparasite. Its original host is the Asian honeybee, Apis cerana, but it has also become a severe, global threat to the European honeybee, Apis mellifera. Previous studies have shown that Varroa can mimic a host's cuticular hydrocarbons (HC), enabling the parasite to escape the hygienic behaviour of the host honeybees. By transferring mites between the two honeybee species, we further demonstrate that Vd is able to mimic the cuticular...

Data from: The complex phylogeography of the Indo-Malayan Alophoixus bulbuls with the description of a putative new ring species complex

Jérôme Fuchs, Per G. P. Ericson, Céline Bonillo, Arnaud Couloux & Eric Pasquet
The Indo-Malayan bioregion has provided some of the most spectacular discoveries of new vertebrate species (e.g. saola, khanyou, bare-faced bulbul) over the last 25 years. Yet, very little is known about the processes that led to the current biodiversity in this region. We reconstructed the phylogeographic history of a group of closely related passerines, the Alophoixus bulbuls. These birds are continuously distributed in Indo-Malaya around the Thailand lowlands such that their distribution resembles a ring....

Data from: Feed or fight: testing the impact of food availability and intraspecific aggression on the functional ecology of an island lizard

Colin M. Donihue, Kinsey M. Brock, Johannes Foufopoulos & Anthony Herrel
Body size often varies among insular populations relative to continental conspecifics – the ‘island rule’ – and functional, context-dependent morphological differences tend to track this body size variation on islands. Two hypotheses are often proposed as potential drivers of insular population differences in morphology: one relating to diet and the other involving intraspecific competition and aggression. We directly tested whether differences in morphology and maximum bite capacity were explained by interisland changes in hardness of...

Data from: Disruptive viability selection on a black plumage trait associated with dominance

Paul Acker, Arnaud Grégoire, Margaux Rat, Claire N. Spottiswoode, René E. Van Dijk, Matthieu Paquet, Jennifer C. Kaden, Roger Pradel, Ben J. Hatchwell, Rita Covas & Claire Doutrelant
Traits used in communication, such as colour signals, are expected to have positive consequences for reproductive success, but their associations with survival are little understood. Previous studies have mainly investigated linear relationships between signals and survival, but both hump-shaped and U-shaped relationships can also be predicted, depending on the main costs involved in trait expression. Furthermore, few studies have taken the plasticity of signals into account in viability selection analyses. The relationship between signal expression...

Data from: Reactive responses of zebras to lion encounters shape their predator-prey space game at large scale

Nicolas Courbin, Andrew J. Loveridge, David W. Macdonald, Hervé Fritz, Marion Valeix, Edwin T. Makuwe & Simon Chamaillé-Jammes
The predator–prey space game and the costs associated with risk effects are affected by prey 1) proactive adjustments (when prey modify their behaviour in response to an a priori assessment of the risk level) and 2) reactive adjustments (when prey have detected an immediate threat). Proactive adjustments are generally well-studied, whereas the frequency, strength and duration of reactive adjustments remain largely unknown. We studied the space use and habitat selection of GPS-collared zebras Equus quagga...

Data from: Contrasting microbial biogeographical patterns between anthropogenic subalpine grasslands and natural alpine grasslands

Roberto A. Geremia, Mihai Pușcaș, Lucie Zinger, Jean-Marc Bonneville, Philippe Choler & Jean-Marc Bonneville
The effect of plant species composition on soil microbial communities was studied at the multiregional level. We compared the soil microbial communities of alpine natural grasslands dominated by Carex curvula and anthropogenic subalpine pastures dominated by Nardus stricta. We conducted paired sampling across the Carpathians and the Alps and used Illumina sequencing to reveal the molecular diversity of soil microbes. We found that bacterial and fungal communities exhibited contrasting regional distributions and that the distribution...

Data from: Stoichiometric imbalances between detritus and detritivores are related to shifts in ecosystem functioning

André Frainer, Jérémy Jabiol, Mark O. Gessner, Andreas Bruder, Eric Chauvet, Brendan McKie & Brendan G. McKie
How are resource consumption and growth rates of litter-consuming detritivores affected by imbalances between consumer and litter C:N:P ratios? To address this question, we offered leaf litter as food to three aquatic detritivore species, which represent a gradient of increasing body N:P ratios: a crustacean, a caddisfly and a stonefly. The detritivores were placed in microcosms and submerged in a natural stream. Four contrasting leaf species were offered, both singly and in two-species mixtures, to...

Data from: Elucidating the spatio-temporal dynamics of an emerging wildlife pathogen using approximate Bayesian computation

Olivier Rey, Lisa Fourtune, Ivan Paz-Vinas, Geraldine Loot, Charlotte Veyssière, Benjamin Roche & Simon Blanchet
Emerging pathogens constitute a severe threat for human health and biodiversity. Determining the status (native or non-native) of emerging pathogens, and tracing back their spatio-temporal dynamics, is crucial to understand the eco-evolutionary factors promoting their emergence, to control their spread and mitigate their impacts. However, tracing back the spatio-temporal dynamics of emerging wildlife pathogens is challenging because (i) they are often neglected until they become sufficiently abundant and pose socio-economical concerns and (ii) their geographical...

Data from: Phylogeographic pattern of range expansion provides evidence for cryptic species lineages in Silene nutans in Western Europe

Hélène Martin, Pascal Touzet, Fabienne Van Rossum, Damien Delalande & Jean-François Arnaud
As a result of recent or past evolutionary processes, a single species might consist of distinct Evolutionary Significant Units (ESUs), even corresponding to cryptic species. Determining the underlying mechanisms of range shifts and the processes at work in the build-up of divergent ESUs requires elucidating the factors that contribute to population genetic divergence across a species’ range. We investigated the large-scale patterns of genetic structure in the perennial herbaceous plant species Silene nutans (Caryophyllaceae) in...

Data from: Odourant dominance in olfactory mixture processing: what makes a strong odourant

M. Schubert, J.C. Sandoz, G.C. Galizia, M. Giurfa, J.-C. Sandoz & G. Galizia
The question of how animals process stimulus mixtures remains controversial as opposing views propose that mixtures are processed analytically, as the sum of their elements, or holistically, as unique entities different from their elements. Overshadowing is a widespread phenomenon that can help decide between these alternatives. In overshadowing, an individual trained with a binary mixture learns one element better at the expense of the other. Although element salience (learning success) has been suggested as a...

Data from: Signal architecture: temporal variability and individual consistency of multiple sexually selected signals

Alexis S. Chaine & Bruce E. Lyon
1. Multiple signals should be favoured when the benefit of additional signals outweigh their costs. Despite increased attention on multiple-signalling systems, few studies have focused on signal architecture to understand the potential information content of multiple signals. 2. To understand the patterns of signal plasticity and consistency over the lifetime of individuals we conducted a longitudinal study of multiple signals known to be under sexual selection in male lark buntings, Calamospiza melanocorys. 3. Within years,...

Data from: Anthropogenic and natural drivers of gene flow in a temperate wild fruit tree: a basis for conservation and breeding programs in apples

Amandine Cornille, Alice Feurtey, Uriel Gélin, Jeanne Ropars, Kristine Misvanderbrugge, Pierre Gladieux & Tatiana Giraud
Gene flow is an essential component of population adaptation and species evolution. Understanding of the natural and anthropogenic factors affecting gene flow is also critical for the development of appropriate management, breeding and conservation programs. Here, we explored the natural and anthropogenic factors impacting crop-to-wild and within wild gene flow in apples in Europe using an unprecedented dense sampling of 1,889 wild apple (Malus sylvestris) from European forests and 339 apple cultivars (Malus domestica). We...

Data from: Plasmodium infection brings forward mosquito oviposition

Julien Vézilier, Antoine Nicot, Sylvain Gandon, Ana Rivero & J. Vezilier
Invertebrate hosts often bring forward their reproductive effort in response to a parasitic infection. This is widely interpreted as a host-driven response aimed at compensating for the expected losses in future fitness as a result of parasitism. Here we report that mosquitoes bring forward their oviposition schedule when they are infected with Plasmodium, a parasite known to severely curtail mosquito fecundity. This response could aim at compensating for a negative time-dependent effect of the parasite...

Data from: Determinants of individual foraging specialisation in large marine vertebrates, the Antarctic and Subantarctic fur seals

Laëtitia Kernaléguen, John P. Y. Arnould, Christophe Guinet & Yves Cherel
1. The degree of individual specialization in resource use differs widely among wild populations where individuals range from fully generalized to highly specialized. This interindividual variation has profound implications in many ecological and evolutionary processes. A recent review proposed four main ecological causes of individual specialization: interspecific and intraspecific competition, ecological opportunity and predation. 2. Using the isotopic signature of subsampled whiskers, we investigated to what degree three of these factors (interspecific and intraspecific competition...

Data from: Spatial variation in age structure among populations of a colonial marine snake: the influence of ectothermy

Xavier Bonnet, François Brischoux, David Pinaud, Richard Shine, Catherine Louise Michel, Jean Clobert & Thomas Fauvel
1. Several tetrapod lineages that have evolved to exploit marine environments (e.g. seals, seabirds, sea kraits) continue to rely upon land for reproduction and, thus, form dense colonies on suitable islands. 2. In birds and mammals (endotherms), the offspring cannot survive without their parents. Terrestrial colonies contain all age classes. In reptiles (ectotherms), this constraint is relaxed, because offspring are independent from birth. Hence, each age class has the potential to select sites with characteristics...

Data from: Is there still a French eating model? A taxonomy of eating behaviors in adults living in the Paris metropolitan area in 2010

Julien Riou, Thomas Lefevre, Isabelle Parizot, Anne Lhuissier & Pierre Chauvin
Background: Meal times in France still represent an important moment in everyday life. The model of three rigorously synchronized meals is still followed by a majority of people, while meal frequencies have flattened in other European or North-American countries. We aimed to examine the “French model” of eating behavior by identifying and characterizing distinct meal patterns. Methods: Analyses were based on data from the SIRS cohort, a representative survey of the adult population in the...

Data from: Contemporary evolution of plant reproductive strategies under global change is revealed by stored seeds

Michel Thomann, Eric Imbert, Rachel C. Engstrand & Pierre-Olivier Cheptou
Global change is expected to impose new selection pressures on natural populations. Phenotypic responses, such as earlier phenology in response to climate warming, have been repeatedly observed in the field. The recent pollinator decline is also expected to change selection on reproductive traits in flowering plants. However, it remains unclear whether short-term adaptation of plant reproductive strategies occurs in response to global change. In this study, we report the evolution of some important reproductive traits...

Data from: Five major shifts of diversification through the long evolutionary history of Magnoliidae (angiosperms)

Julien Massoni, Thomas L. P. Couvreur & Hervé Sauquet
With 10,000 species, Magnoliidae are the largest clade of flowering plants outside monocots and eudicots. Despite an ancient and rich fossil history, the tempo and mode of diversification of Magnoliidae remain poorly known. Using a molecular data set of 12 markers and 220 species (representing >75% of genera in Magnoliidae) and six robust, internal fossil age constraints, we estimate divergence times and significant shifts of diversification across the clade. In addition, we test the sensitivity...

Data from: Phenotypic variability in unicellular organisms: from calcium signaling to social behavior

David Vogel, Stamatios C. Nicolis, Alfonso Perez-Escudero, Vidyanand Nanjundiah, David J. T. Sumpter & Audrey Dussutour
Historically, research has focused on the mean and often neglected the variance. However, variability in nature is observable at all scales: among cells within an individual, among individuals within a population and among populations within a species. A fundamental quest in biology now is to find the mechanisms that underlie variability. Here, we investigated behavioural variability in a unique unicellular organism, Physarum polycephalum. We combined experiments and models to show that variability in cell signalling...

Data from: New fossil Hyaenodonta (Mammalia, Placentalia) from the Ypresian and Lutetian of France and the evolution of the Proviverrinae in southern Europe

Floréal Solé, Jocelyn Falconnet & Dominique Vidalenc
The proviverrines from the Ypresian (MP7–MP10) and Lutetian (MP11–MP14) are represented mainly by species recorded in the northern and central parts of Europe (Paris Basin, Belgian Basin, Germany, Switzerland). Here, we describe fossils from southern France: Saint-Papoul (MP8 + 9; Aude) and Aigues-Vives 2 (?MP13; Aude). One dentary with secant molars from Saint-Papoul represents a new genus and species, Preregidens langebadrae. This taxon is possibly present in Avenay (France), the MP8 + 9 reference locality....

Data from: Seascape genetics along environmental gradients in the Arabian Peninsula: insights from ddRAD sequencing of anemonefishes

Pablo Saenz-Agudelo, Joseph D. DiBattista, Marek J. Piatek, Michelle R. Gaither, Hugo B. Harrison, Gerrit B. Nanninga & Michael L. Berumen
Understanding the processes that shape patterns of genetic structure across space is a central aim of landscape genetics. However, it remains unclear how geographic features and environmental variables shape gene flow, particularly for marine species in large complex seascapes. Here, we evaluated the genomic composition of the two-band anemonefish Amphiprion bicinctus across its entire geographic range in the Red Sea and Gulf of Aden, as well as its close relative, Amphiprion omanensis endemic to the...

Data from: Hybridization promotes speciation in Coenonympha butterflies

Thibaut Capblancq, Laurence Després, Delphine Rioux & Jesus Mavarez
Hybridization has become a central element in theories of animal evolution during the last decade. New methods in population genomics and statistical model testing now allow the disentangling of the complexity that hybridization brings into key evolutionary processes such as local adaptation, colonization of new environments, species diversification and extinction. We evaluated the consequences of hybridization in a complex of three alpine butterflies in the genus Coenonympha, by combining morphological, genetic and ecological analyses. A...

Data from: Non-consumptive effects of a top-predator decrease the strength of the trophic cascade in a four-level terrestrial food web

Elvire Bestion, Julien Cucherousset, Aimeric Teyssier & Julien Cote
The fear of predators can strongly impact food web dynamics and ecosystem functioning through effects on herbivores morphology, physiology or behaviour. While non-consumptive predator effects have been mostly studied in three-level food chains, we lack evidence for the propagation of non-consumptive indirect effects of apex predators in four level food-webs, notably in terrestrial ecosystems. In experimental mesocosms, we manipulated a four-level food chain including top-predator cues (snakes), mesopredators (lizards), herbivores (crickets), and primary producers (plants)....

Data from: Costs of CRISPR-Cas mediated resistance in Streptococcus thermophilus

Pedro F. Vale, Guillaume Lafforgue, François Gatchitch, Rozenn Gardan, Sylvain Moineau & Sylvain Gandon
CRISPR-Cas is a form of adaptive sequence-specific immunity in microbes. This system offers unique opportunities for the study of coevolution between bacteria and their viral pathogens, bacteriophages. A full understanding of the coevolutionary dynamics of CRISPR-Cas requires knowing the magnitude of the cost of resisting infection. Here, using the gram-positive bacterium Streptococcus thermophilus and its associated virulent phage 2972, a well-established model system harbouring at least two type II functional CRISPR-Cas systems, we obtained different...
