Honey bee lifespan: the critical role of pre-foraging stage

Alberto Prado, Fabrice Requier, Didier Crauser, Yves Le Conte, Vincent Bretagnolle & Cedric Alaux
Assessing the various anthropogenic pressures imposed on honey bees requires characterizing the patterns and drivers of natural mortality. Using automated life-long individual monitoring devices, we monitored worker bees in different geographical, seasonal and colony contexts creating a broad range of hive conditions. We measured their life-history traits and notably assessed whether lifespan is influenced by pre-foraging flight experience. Our results show that the age at the first flight and onset of foraging are critical factors...

Trait-dependency of trophic interactions in zooplankton food webs

Florian Vincent, Andrea Bertolo, Gérard Lacroix, Maud Mouchet & Eric Edeline
Anthropogenic change in the abundance or identity of dominant top predators may induce reorganizations in whole food webs. Predicting these reorganizations requires identifying the biological rules that govern trophic niches. However, we still lack a detailed understanding of the respective contributions of body size, behaviour (e.g., match between predator hunting mode and prey antipredator strategy), phylogeny and/or ontogeny in determining both the presence and strength of trophic interactions. Here, we address this question by measuring...

Disentangling the roles of bottom-up and top-down drivers in the trade-off between food acquisition and safety in prey with multiple predators

Olivier Pays, Pierrick Blanchard, Simon Chamaillé-Jammes, Marion Valeix, Andrew Loveridge, David Macdonald, Stéphanie Périquet, Esther Van Der Meer, Patrick Duncan, Godfrey Mtare & Herve Fritz
1. Prey face a trade-off between acquiring food and avoiding predation, but food availability, and therefore its effect, is rarely measured in field studies investigating non-lethal effects of predation. The main aim of this study is to investigate the role of the presence of predators in the functional adjustments of feeding parameters with patch quality in a medium-size herbivore. 2. In Hwange National Park (Zimbabwe), we set up an experiment by manipulating, over two years,...

Data from: Cranial evolution in the extinct Rodrigues Island owl Otus murivorus (Strigidae), associated with unexpected ecological adaptations

Antoine Louchart, Anaïs Duhamel, Julian Hume, Pauline Guenser & Céline Salaviale
Island birds that were victim of anthropic extinctions were often more specialist species, having evolved their most distinctive features in isolation. Here we studied a fossil cranium of the ‘giant’ extinct scops owl Otus murivorus from Rodrigues Island (Mascarene Islands, southwestern Indian Ocean), to determine any potential unique characters. The fossil and extant strigids were imaged through x-ray microtomography, providing 3D views of external and internal (endocast, inner ear) cranial structures. Geometric morphometrics and analyses...

Data from: Are fission-fusion dynamics consistent among populations? A large-scale study with Cape buffalo

Elodie Wielgus, Daniel Cornélis, Michel De Garine-Wichatitsky, Bradley Cain, Hervé Fritz, Eve Miguel, Hugo Valls-Fox, Alexandre Caron & Simon Chamaillé-Jammes
Fission-fusion dynamics allow animals to manage costs and benefits of group living by adjusting group size. The degree of intraspecific variation in fission-fusion dynamics across the geographical range is poorly known. During 2008-2016, 38 adult female Cape buffalo were equipped with GPS collars in three populations located in different protected areas (Gonarezhou National Park and Hwange National Park, Zimbabwe; Kruger National Park, South Africa) to investigate the patterns and environmental drivers of fission-fusion dynamics among...

Data from: Reproductives and eggs trigger worker vibration in a subterranean termite

Fanny Ruhland, Marion Moulin, Marina Choppin, Joël Meunier & Christophe Lucas
In insect societies, the presence of reproductives or eggs has been shown to shape several biological traits in the colony members. Social interactions are one of these traits, that involve modification of the communication system of the entire colony. Many studies described the role of chemical compounds and dominance behaviors in the presence of reproductive but vibratory behaviors received very few investigations. Yet, vibratory behaviors are ideal candidates, particularly for subterranean species like termites, as...

Data from: Canonical correlations reveal adaptive loci and phenotypic responses to climate in perennial ryegrass

José L. Blanco-Pastor, Philippe Barre, Thomas Keep, Thomas Ledauphin, Abraham Escobar-Gutiérrez, Anna Maria Roschanski, Evelyn Willner, Klaus Dehmer, Matthew Hegarty, Hilde Muylle, Elisabeth Veeckman, Klaas Vandepoele, Tom Ruttink, Isabel Roldán-Ruiz, Stéphanie Manel & Jean-Paul Sampoux
Germplasm from perennial ryegrass (Lolium perenne L.) natural populations is useful for breeding because of its adaptation to a wide range of climates. Climate-adaptive genes can be detected from associations between genotype, phenotype and climate but an integrated framework for the analysis of these three sources of information is lacking. We used two approaches to identify adaptive loci in perennial ryegrass and their effect on phenotypic traits. First, we combined Genome-Environment Association (GEA) and GWAS...

Data from: Foraging behaviour and habitat-use drives niche segregation in sibling seabird species

Ryan Reisinger, Tegan Carpenter-Kling, Maëlle Connan, Yves Cherel & Pierre Pistorius
To mediate competition, similar sympatric species are assumed to utilise different resources, or the same but geographically separated resources. The two giant petrels (Macronectes spp.) are intriguing in that they are morphologically similar seabirds with overlapping diets and distributions. To better understand the mechanisms allowing their co-existence, we investigated intra- and interspecific niche segregation at Marion Island (Southern Indian Ocean), one of the few localities where they breed in sympatry. We used GPS tracks from...

Young frigatebirds learn how to compensate for wind-drift

Joe Wynn, Oliver Padget, Julien Collet, Aurélien Prudor, Alexandre Corbeau & Henri Weimerskirch
Compensating for wind drift can improve goalward flight efficiency in animal taxa, especially amongst those that rely on thermal soaring to travel large distances. Little is known, however, about how animals acquire this ability. The great frigatebird (Fregata minor) exemplifies the challenges of wind drift compensation because it lives a highly pelagic lifestyle, traveling very long distances over the open ocean but without the ability to land on water. Using GPS tracks from fledgling frigatebirds,...

Data from: Plasticity matches phenotype to local conditions despite genetic homogeneity across 13 snake populations

Xavier Bonnet
In a widespread species, a matching of phenotypic traits to local environmental optima is generally attributed to site-specific adaptation. However, the same matching can occur via adaptive plasticity, without requiring genetic differences among populations. Adult sea kraits (Laticauda saintgironsi) are highly philopatric to small islands, but the entire population within the Neo-Caledonian lagoon is genetically homogenous because females migrate to the mainland to lay their eggs at communal sites; recruits disperse before settling, mixing up...

Data from: Extending full protection inside existing marine protected areas or reducing fishing effort outside can reconcile conservation and fisheries goals

Mokrane Belharet, Antonio Di Franco, Antonio Calò, Lorenzo Mari, Joachim Claudet, Renato Casagrandi, Marino Gatto, Josep Lloret, Charlotte Sève, Paolo Guidetti & Paco Melià
1. Most fish stocks worldwide are fished at maximum sustainable yield (MSY) or overfished, as many fisheries management strategies have failed to achieve sustainable fishing. Identifying effective fisheries management strategies has now become urgent. 2. Here, we developed a spatially-explicit metapopulation model accounting for population connectivity in the north-western Mediterranean Sea, and parameterized it for three ecologically and economically important coastal fish species: the white seabream Diplodus sargus, the two-banded seabream Diplodus vulgaris and the...

Rapid and repeated divergence of animal chemical signals in an island introduction experiment

Colin Donihue, Anthony Herrel, José Martín, Johannes Foufopoulos, Panayiotis Pafilis & Simon Baeckens
Studies of animal communication have documented myriad rapid, context-dependent changes in visual and acoustic signal design. In contrast, relatively little is known about the capacity of vertebrate chemical signals to rapidly respond, either plastically or deterministically, to changes in context. Four years following an experimental introduction of lizards to replicate experimental islets, we aimed to determine if chemical signal design of the experimental populations differed from that of the source population. In 2014, we translocated...

Disentangling the assembly mechanisms of ant cuticular bacterial communities of two Amazonian ant species sharing a common arboreal nest

Caroline Birer, Corrie S. Moreau, Niklas Tysklind, Lucie Zinger & Christophe Duplais
Bacteria living on the cuticle of ants are generally studied for their protective role against pathogens, especially in the clade of fungus-growing ants. However, little is known of the diversity of cuticular bacteria in other ant host species, as well as of the mechanisms leading to the composition of these communities. Here, we used 16S rRNA gene amplicon sequencing to study the influence of host species, species interactions, and the pool of bacteria from the...

Positive and negative interactions jointly determine the structure of Müllerian mimetic communities

Thomas G. Aubier & Marianne Elias
Negative and positive ecological interactions have opposite effects on the structure of ecological communities, in particular in terms of ecological similarity among interacting species. In nature, species belonging to the same guild often interact in both negative and positive ways, yet the interplay between interactions of different kinds in intraguild community dynamics remains poorly understood. Müllerian mimetic communities are particularly suited for investigating this interplay because positive (mutualistic mimicry) and negative (competition for trophic resource...

Unidirectional response to bidirectional selection on body size. I. Phenotypic, life history and endocrine response

Clémentine Renneville, Alexis Millot, Simon Agostini, David Carmignac, Gersende Maugars, Sylvie Dufour, Arnaud Le Rouzic & Eric Edeline
Anthropogenic perturbations such as harvesting often select against a large body size and are predicted to induce rapid evolution towards smaller body sizes and earlier maturation. However, body-size evolvability and, hence, adaptability to anthropogenic perturbations remain seldom evaluated in wild populations. Here, we use a laboratory experiment over 6 generations to measure the ability of wild-caught medaka fish (Oryzias latipes) to evolve in response to bidirectional size-dependent selection mimicking opposite harvest regimes. Specifically, we imposed...

Don’t judge a lizard by its colour: no evidence for differential socio-sexual behaviour and space use in the colour morphs of the European common wall lizard (Podarcis muralis)

Javier Abalos, Guillem Pérez I De Lanuza, Alicia Bartolomé, Océane Liehrmann, Hanna Laakkonen, Fabien Aubret, Tobias Uller, Pau Carazo & Enrique Font
Explaining the evolutionary origin and maintenance of colour polymorphisms is a major challenge in evolutionary biology. Such polymorphisms are commonly thought to reflect the existence of alternative behavioural or life-history strategies under negative frequency-dependent selection. The European common wall lizard Podarcis muralis exhibits a striking ventral colour polymorphism that has been intensely studied and is often assumed to reflect alternative reproductive strategies, similar to the iconic “rock-paper-scissors” system described in the North American lizard Uta...

Trait strengthening in mussels

Laurent Seuront, Katy Nicastro, Christopher McQuaid & Gerardo Zardi
Plastic pollution is ubiquitous with increasing recognition of its direct effects on species’ fitness. Little is known, however, about its more subtle effects, including the influence of plastic pollution on the morphological, functional and behavioural traits of organisms that are central to their ability to withstand disturbances. Among the least obvious but most pernicious forms of plastic-associated pollution are the chemicals that leach from microplastics. Here, we investigate how such leachates influence species’ traits by...
