Data from: A comparison between transcriptome sequencing and 16S metagenomics for detection of bacterial pathogens in wildlife

Background: Rodents are major reservoirs of pathogens responsible for numerous zoonotic diseases in humans and livestock. Assessing their microbial diversity at both the individual and population level is crucial for monitoring endemic infections and revealing microbial association patterns within reservoirs. Recently, NGS approaches have been employed to characterize microbial communities of different ecosystems. Yet, their relative efficacy has not been assessed. Here, we compared two NGS approaches, RNA-Sequencing (RNA-Seq) and 16S-metagenomics, assessing their ability to...

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...

Data from: Escape of spring frost and disease through phenological variations in oak populations along elevation gradients

Cécile Françoise Dantec, Hugo Ducasse, Xavier Capdevielle, Olivier Fabreguettes, Sylvain Delzon & Marie-Laure Desprez-Loustau
1. The timing of tree flushing follows strong phenotypic and genetic clines across environmental gradients. It may be seen as an adaptive response to abiotic (escape of spring frost and maximizing growing season length) and biotic (escape of pest and disease) hazards. However, few studies have investigated jointly both types of hazards. 2. We assessed exposure to both abiotic (spring frost) and biotic (powdery mildew) hazards within and between sessile oak populations along elevation gradients,...

Data from: Ecologically diverse and distinct neighbourhoods trigger persistent phenotypic consequences, and amine metabolic profiling detects them

Françoise Hennion, Isabelle Litrico, Igor Bartish, Alexandra Weigelt, Alain Bouchereau & Andreas Prinzing
1.Global change triggers rapid alterations in the composition and diversity of plant communities which may change ecosystem functioning. Do changes in community diversity also change traits persistently, i.e. does coexistence with numerous or functionally or phylogenetically distinct species trigger, in a given focal species, trait shifts that persist? 2.We studied the grass Dactylis glomerata. Dactylis was grown in experimental plots with different species compositions for five years, sampled, cloned and grown in a common garden....

Data from: Temporal dynamics of seed excretion by wild ungulates: implications for plant dispersal

Mélanie Picard, Julien Papaïx, Frédéric Gosselin, Denis Picot, Eric Bideau & Christophe Baltzinger
Dispersal is a key process in metapopulation dynamics as it conditions species' spatial responses to gradients of abiotic and biotic conditions and triggers individual and gene flows. In the numerous plants that are dispersed through seed consumption by herbivores (endozoochory), the distance and effectiveness of dispersal is determined by the combined effects of seed retention time in the vector's digestive system, the spatial extent of its movements, and the ability of the seeds to germinate...

Data from: No early gender effects on energetic status and life history in a salmonid.

Thomas Regnier, Jacques Labonne, Joëlle Chat, Ayaka Yano, Yann Guiguen & Valérie Bolliet
Throughout an organism's early development, variations in physiology and behaviours may have long lasting consequences on individual life histories. While a large part of variation in critical life-history transitions remains unexplained, a significant proportion may be caused by early gender effects as part of gender-specific life histories shaped by sexual selection. In this study, we investigated the presence of early gender effects on the timing of emergence from gravel and the energetic status of brown...

Data from: The genetics of intra- and interspecific competitive response and effect in a local population of an annual plant species

Baron Etienne, Richirt Julien, Villoutreix Romain, Amsellem Laurent, Fabrice Roux & Etienne Baron
While competition is recognized as a major factor responsible for plant community dynamics, the genetics of intra- and interspecific competitive ability of a target species (i.e. level of intra-population genetic variation, identity of phenotypic traits under selection and genetic bases) still deserves a deeper investigation at the local spatial scale by considering both numerous genotypes and several interacting species In this study, we tested whether the genetics of competitive response and effect in Arabidopsis thaliana...

Data from: Assessing early fitness consequences of exotic gene flow in the wild: a field study with Iberian pine relicts

Gregor M. Unger, Myriam Heuertz, Giuseppe G. Vendramin & Juan J. Robledo-Arnuncio
Gene flow from plantations of nonlocal (genetically exotic) tree provenances into natural stands of the same species is probably a widespread phenomenon, but its effects remain largely unexamined. We investigated early fitness consequences of intraspecific exotic gene flow in the wild by assessing differences in survival among native, nonlocal, and F1 intraspecific hybrid seedlings naturally established within two native pine relicts (one of Pinus pinaster and the other of P. sylvestris) surrounded by nonlocal plantations....

Data from: Correlation between the green-island phenotype and Wolbachia infections during the evolutionary diversification of Gracillariidae leaf-mining moths

Florence Gutzwiller, Franck Dedeine, Wilfried Kaiser, David Giron & Carlos Lopez-Vaamonde
Internally feeding herbivorous insects such as leaf miners have developed the ability to manipulate the physiology of their host plants in a way to best meet their metabolic needs and compensate for variation in food nutritional composition. For instance, some leaf miners can induce green-islands on yellow leaves in autumn, which are characterized by photosynthetically active green patches in otherwise senescing leaves. It has been shown that endosymbionts, and most likely bacteria of the genus...

Data from: Adaptive plasticity and niche expansion in an invasive thistle

Kathryn G. Turner, Hélène Fréville & Loren H. Rieseberg
Phenotypic differentiation in size and fecundity between native and invasive populations of a species has been suggested as a causal driver of invasion in plants. Local adaptation to novel environmental conditions through a micro-evolutionary response to natural selection may lead to phenotypic differentiation and fitness advantages in the invaded range. Local adaptation may occur along a stress tolerance trade-off, favoring individuals that, in benign conditions, shift resource allocation from stress tolerance to increased vigor and...

Data from: Neutral and adaptive drivers of microgeographic genetic divergence within continuous populations: the case of the Neotropical tree Eperua falcata (Aubl.)

Louise Brousseau, Matthieu Foll, Caroline Scotti-Saintagne & Ivan Scotti
Background: In wild plant populations, genetic divergence within continuous stands is common, sometimes at very short geographical scales. While restrictions to gene flow combined with local inbreeding and genetic drift may cause neutral differentiation among subpopulations, microgeographical variations in environmental conditions can drive adaptive divergence through natural selection at some targeted loci. Such phenomena have recurrently been observed in plant populations occurring across sharp environmental boundaries, but the interplay between selective processes and neutral genetic...

Data from: Modeling spatial expansion of invasive alien species: relative contributions of environmental and anthropogenic factors to the spreading of the harlequin ladybird in France

Sophie Veran, Sylvain Piry, Vincent Ternois, Christine N. Meynard, Benoit Facon & Arnaud Estoup
Species distribution models (SDM) have often been used to predict the potential ranges of introduced species and prioritize management strategies. However, this approach assumes equilibrium between occurrences and environmental gradients, an assumption which is violated during the invasion process, where many suitable sites are empty because the species has not yet reached them. Here we considered the invasive ladybird Harmonia axyridis as a case study to show the benefits of using a dynamic colonization–extinction model...
