Changes in foraging mode caused by a decline in prey size have major bioenergetic consequences for a small pelagic fish

Elisa Thoral, Quentin Queiros, Damien Roussel, Gilbert Dutto, Eric Gasset, David McKenzie, Caroline Romestaing, Jean-Marc Fromentin, Claire Saraux & Loic Teulier
Global warming is causing profound modifications of aquatic ecosystems and one major outcome appears to be a decline in adult size of many fish species. Over the last decade, sardine populations in the Gulf of Lions (NW Mediterranean Sea) have shown severe declines in body size and condition as well as disappearance of the oldest individuals, which could not be related to overfishing, predation pressure, or epizootic diseases. In this study, we investigated whether this...

Assessing the effects of artificial light at night on biodiversity across latitude – Current knowledge gaps

Jean Secondi, Aurélie Davranche, Marc Théry, Nathalie Mondy & Thierry Lengagne
Aim: Exposure to artificial light at night (ALAN) is a risk factor for organisms. Considering the spread and increasing intensity of night brightness across the globe, and the key role of light at all biological levels, alterations of ecosystems are expected. Yet, we cannot predict the severity of the effects of ALAN in several biomes because little information is available outside the temperate zone. We reviewed current knowledge and identified traits that could be targeted...

An invasive amphibian drives antipredator responses in two prey at different trophic positions

Jean Secondi & Fanny Raux
Generalist invasive predators consume prey at different trophic levels and generate drastic changes in local communities. However, the long-term effects of predation may be reduced by eco-evolutionary responses of native populations. The capacity of prey species distributed across the trophic network to develop antipredator responses may determine the ecosystem potential to buffer against the invader. The African clawed frog is a major invader on several continents. Because of its large size, generalist diet, and aquatic...

Combined palaeohistological and isotopic inferences of thermometabolism in extinct Neosuchia, using Goniopholis and Dyrosaurus (Pseudosuchia: Crocodylomorpha) as case studies

Mathieu Faure-Brac, Romain Amiot, Christian De Muizon, Jorge Cubo & Christophe Lécuyer
The evolution of thermometabolism in pseudosuchians (Late Triassic to the present) remains a partly unsolved issue: extant taxa (crocodilians) are ectothermic, but the clade was inferred ancestrally endothermic. Here we inferred the thermometabolic regime of two neosuchian groups, Goniopholididae (Early Jurassic to Late Cretaceous) and Dyrosauridae (Middle Cretaceous to Late Eocene), close relatives of extant crocodilians, in order to elucidate the evolutionary pattern across Metasuchia (Early Jurassic to the present), a clade comprising Neosuchia (Early...

Evolution of large males is associated with female-skewed adult sex ratios in amniotes

András Liker, Veronika Bókony, Ivett Pipoly, Jean-François Lemaître, Jean-Michel Gaillard, Tamas Szekely & Robert P. Freckleton
Body size often differs between the sexes (leading to sexual size dimorphism, SSD), as a consequence of differential responses by males and females to selection pressures. Adult sex ratio (the proportion of males in the adult population, ASR) should influence SSD because ASR relates to both the number of competitors and available mates, which shape the intensity of mating competition and thereby promotes SSD evolution. However, whether ASR correlates with SSD variation among species has...

Assortative mating for between-patch dispersal status in a wild bird population: Exploring the role of direct and indirect underlying mechanisms

Thibault Tamin & Blandine Doligez
Previous studies have reported functional integration between dispersal and other phenotypic traits allowing individuals to alleviate dispersal costs, and such associations can affect dispersal evolution in return. In sexually reproducing species, assortative mating according to dispersal can shape the maintenance of such trait associations. Despite the potentially crucial consequences of dispersal in natural populations, assortative mating for dispersal and its underlying mechanisms remain largely unexplored. Here, we assessed assortative mating for between-patch dispersal status in...

Data from: The intrinsically disordered N-terminus of the voltage-dependent anion channel

Jordane Preto
The voltage-dependent anion channel (VDAC) is a beta-barrel membrane protein of the mitochondrial outer membrane (MOM), which controls the transport of ions and ATP between mitochondria and the cytoplasm. The present dataset includes all data and scripts generated in the study "The intrinsically-disordered N-terminus of the voltage-dependent anion channel" by J. Preto and I. Krimm, where we performed all-atom simulations to investigate the disordered properties of VDAC’s N-terminus (i) as a free peptide in solution...

Data from: Effects of age and disease duration on excess mortality in patients with multiple sclerosis from a French nationwide cohort

Fabien Rollot
Objective: To determine the effects of current age and disease duration on excess mortality in multiple sclerosis, we described the dynamics of excess deaths rates over these two time scales and studied the impact of age at multiple sclerosis clinical onset on these dynamics, separately in each initial phenotype. Methods: We used data from 18 French multiple sclerosis expert centers participating in the Observatoire Français de la Sclérose en Plaques. Patients with multiple sclerosis living...

Artificial light at night alters activity, body mass and corticosterone level in a tropical anuran

Jean Secondi, Nathalie Mondy, Jérôme M.W. Gippet, Morgane Touzot, Vanessa Gardette, Ludovic Guillard & Thierry Lengagne
Photoperiod is a major factor regulating biological rhythms in animals and plants. At low latitudes, annual variation in daylength is low and species are expected to strongly rely on photic cues to reset their circadian clocks. A corollary is that individuals should be strongly affected by sudden changes in the photic regime as those generated by artificial light at night (ALAN). We tested this hypothesis in an anuran in Costa Rica (10°N). Using an outdoor...

Genotypes of Italian free-ranging dogs

Eugenia Natoli, Roberto Bonnani, Simona Cafazzo, Daniel Mills, Dominique Pontier & Malgorzata Pilot
Domestication has greatly changed the social and reproductive behavior of dogs relative to that of wild members of the genus Canis, which typically exhibit social monogamy and extended parental care. Unlike a typical grey wolf pack that consists of a single breeding pair and their offspring from multiple seasons, a group of free-ranging dogs (FRDs) can include multiple breeding individuals of both sexes. To understand the consequences of this shift in reproductive behavior, we reconstructed...

Dataset and script to: Morphometric variance, evolutionary constraints and their change through time in Late Devonian Palmatolepis conodonts

Sabrina Renaud, Catherine Girard & Anne-Béatrice Dufour
Phenotypic variation is the raw material of evolution. Standing variation can facilitate response to selection along “lines of least evolutionary resistance”, but selection itself might alter the structure of the variance. Shape was quantified using 2D geometric morphometrics in Palmatolepis conodonts through the Late Devonian period. Patterns of variance were characterized along the record by the variance-covariance matrix (P-matrix) and its first axis (Pmax). The Late Frasnian was marked by environmental oscillations culminating with the...

Data on paternal age and sperm production of the progeny

Gabriele Sorci, Pauline Vuarin, Loïc Lesobre, Gwènaëlle Levêque, Michel Saint Jalme, Frédéric Lacroix & Yves Hingrat
Parental age has profound consequences for offspring’s phenotype. However, whether patrilineal age affects offspring sperm production is unknown, despite the importance of sperm production for male reproductive success in species facing post-copulatory sexual selection. Using a longitudinal dataset on ejaculate attributes of the houbara bustard, we showed that offspring sired by old fathers had different age-dependent trajectories of sperm production compared to offspring sired by young fathers. Specifically, they produced less sperm (-48%) in their...

Metagenomics data of the bacterial community in Bemisia tabaci from Burkina Faso

Laurence Mouton, Rahim Romba, Hélène Henri, Fabrice Vavre, Zainab Belgaidi & Olivier Gnankiné
Microbial symbionts are widespread in insects and some of them have been associated to adaptive changes. Primary symbionts (P-symbionts) have a nutritional role that allows their hosts to feed on unbalanced diets (plant sap, wood, blood). Most of them have undergone genome reduction, but their genomes still retain genes involved in pathways that are necessary to synthesize the nutrients that their hosts need. However, in some P-symbionts, essential pathways are incomplete and secondary symbionts (S-symbionts)...

Genetic and species-level biodiversity patterns are linked by demography and ecological opportunity

Chloé Schmidt, Stéphane Dray & Colin J Garroway
The processes that give rise to species richness gradients are not well understood, but may be linked to resource-based limits on the number of species a region can support. Ecological limits placed on regional species richness should also affect population demography, suggesting that these processes could also generate genetic diversity gradients. If true, we might better understand how broad-scale biodiversity patterns are formed by identifying the common causes of genetic diversity and species richness. We...
