Data from: Uropygial gland size and composition varies according to experimentally modified microbiome in Great tits

Staffan Jacob, Anika Immer, Sarah Leclaire, Nathalie Parthuisot, Christine Ducamp, Gilles Espinasse & Philipp Heeb
Background: Parasites exert important selective pressures on host life history traits. In birds, feathers are inhabited by numerous microorganisms, some of them being able to degrade feathers or lead to infections. Preening feathers with secretions of the uropygial gland has been found to act as an antimicrobial defence mechanism, expected to regulate feather microbial communities and thus limit feather abrasion and infections. Here, we used an experimental approach to test whether Great tits (Parus major)...

Data from: The population biology of fungal invasions

Pierre Gladieux, Alice Feurtey, Michael E. Hood, Alodie Snirc, Joanne Clavel, Cyril Dutech, Melanie Roy & Tatiana Giraud
Fungal invasions are increasingly recognized as a significant component of global changes, threatening ecosystem health and damaging food production. Invasive fungi also provide excellent models to evaluate the generality of results based on other eukaryotes. We first consider here the reasons why fungal invasions have long been overlooked: they tend to be inconspicuous, and inappropriate methods have been used for species recognition. We then review the information available on the patterns and mechanisms of fungal...

Data from: High-resolution forest mapping for behavioural studies in the nature reserve ‘Les Nouragues’, French Guiana

Max Ringler, Rosanna Mangione, Andrius Pašukonis, Gerhard Rainer, Kristin Gyimesi, Julia Felling-Wagner, Hannes Kronaus, Maxime Réjou-Méchain, Jérôme Chave, Karl Reiter & Eva Ringler
For animals with spatially complex behaviours at relatively small scales, the resolution of a global positioning system (GPS) receiver location is often below the resolution needed to correctly map animals’ spatial behaviour. Natural conditions such as canopy cover, canyons or clouds can further degrade GPS receiver reception. Here we present a detailed, high-resolution map of a 4.6 ha Neotropical river island and a 8.3 ha mainland plot with the location of every tree >5 cm...

Data from: Maternal exposure to predator scents: offspring phenotypic adjustment and dispersal

Elvire Bestion, Aimeric Teyssier, Fabien Aubret, Jean Clobert & Julien Cote
Predation is a strong selective pressure generating morphological, physiological and behavioural responses in organisms. As predation risk is often higher during juvenile stages, antipredator defences expressed early in life are paramount to survival. Maternal effects are an efficient pathway to produce such defences. We investigated whether maternal exposure to predator cues during gestation affected juvenile morphology, behaviour and dispersal in common lizards (Zootoca vivipara). We exposed 21 gravid females to saurophagous snake cues for one...

Data from: Shotgun microbial profiling of fossil remains

Clio Der Sarkissian, Luca Ermini, Hákon Jónsson, Anatoly N. Alekseev, Éric Crubézy, Beth Shapiro & Ludovic Orlando
Millions to billions of DNA sequences can now be generated from ancient skeletal remains thanks to the massive throughput of next-generation sequencing platforms. Except in cases of exceptional endogenous DNA preservation, most of the sequences isolated from fossil material do not originate from the specimen of interest, but instead reflect environmental organisms that colonized the specimen after death. Here, we characterize the microbial diversity recovered from seven ca. 200-13,000 year old horse bones collected from...

Data from: Seasonality in communication and collective decision-making in ants

Nathalie Stroeymeyt, Caroline Jordan, Gregory Mayer, Sarah Hovsepian, Martin Giurfa & Nigel R. Franks
The ability of animals to adjust their behaviour according to seasonal changes in their ecology is crucial for their fitness. Eusocial insects display strong collective behavioural seasonality, yet the mechanisms underlying such changes are poorly understood. We show that nest preference by emigrating Temnothorax albipennis ant colonies is influenced by a season-specific modulatory pheromone that may help tune decision-making according to seasonal constraints. The modulatory pheromone triggers aversion towards low-quality nests and enhances colony cohesion...

Data from: The genetic structure of Asian corn borer, Ostrinia furnacalis, populations in China: haplotype variance in Northern populations and potential impact on management of resistance to transgenic maize

Jing Li, Brad S. Coates, Kyung Seok Kim, Denis Bourguet, Sergine Ponsard, Kanglai He & Zhenying Wang
Asian corn borer, Ostrinia furnacalis (Guenée), is a severe pest that infests cultivated maize in the major production regions of China. Populations show genotype-by-environment variation in voltinism, such that populations with a single generation (univoltine) are fixed in Northern China where growing seasons are short. Low genetic differentiation was found among samples from 33 collection sites across China and one site from North Korea (n = 1,673) using variation at 6 nuclear microsatellite loci (ENA...

Data from: Patterns of selection on Plasmodium falciparum erythrocyte binding antigens after the colonisation of the New World

Erhan Yalcindag, Virginie Rougeron, Eric Elguero, Céline Arnathau, Patrick Durand, Sylvain Brisse, Laure Diancourt, Agnes Aubouy, Pierre Becquart, Umberto D'Alessandro, Didier Fontenille, Dionicia Gamboa, Amanda Maestre, Didier Ménard, Lise Musset, Oscar Noya, Vincent Veron, Albina Wide, Bernard Carme, Eric Legrand, Christine Chevillon, Francisco J. Ayala, François Renaud & Franck Prugnolle
Pathogens, which have recently colonized a new host species or new populations of the same host, are interesting models for understanding how populations may evolve in response to novel environments. During its colonization of South America from Africa Plasmodium falciparum, the main agent of malaria, has been exposed to new conditions in distinctive new human populations (Amerindian and populations of mixed origins), that likely exerted new selective pressures on the parasite's genome. Among the genes...

Data from: Genome skimming by shotgun sequencing helps resolve the phylogeny of a pantropical tree family

Pierre-Jean G. Malé, Léa Bardon, Guillaume Besnard, Eric Coissac, Frédéric Delsuc, Julien Engel, Emeline Lhuillier, Caroline Scotti-Saintagne, Alexandra Tinaut & Jérôme Chave
Whole genome sequencing is helping generate robust phylogenetic hypotheses for a range of taxonomic groups that were previously recalcitrant to classical molecular phylogenetic approaches. As a case study, we performed a shallow shotgun sequencing of eight species in the tropical tree family Chrysobalanaceae to retrieve large fragments of high-copy number DNA regions and test the potential of these regions for phylogeny reconstruction. We were able to assemble the nuclear ribosomal cluster (nrDNA), the complete plastid...
