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: Within-range translocations and their consequences in European larch

Stefanie Wagner, Sascha Liepelt, Sophie Gerber & Rémy J. Petit
In contrast to biological invasions, translocations of individuals within a species range are understudied, due to difficulties in systematically detecting them. This results in limited knowledge about the corresponding processes and uncertainties regarding the status of extant populations. European larch, a forest tree whose fragmented native distribution is restricted to the Alps and to other Central European mountains, has been massively planted for at least 300 years. Here we focus on the genetic characterization of...

Data from: Globally, functional traits are weak predictors of juvenile tree growth, and we do not know why

1. Plant functional traits, in particular specific leaf area (SLA), wood density and seed mass, are often good predictors of individual tree growth rates within communities. Individuals and species with high SLA, low wood density and small seeds tend to have faster growth rates. 2. If community-level relationships between traits and growth have general predictive value, then similar relationships should also be observed in analyses that integrate across taxa, biogeographic regions and environments. Such global...

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: Single-nucleotide polymorphism discovery and validation in high-density SNP array for genetic analysis in European white oaks

Camille Lepoittevin, Catherine Bodénès, Emilie Chancerel, Laure Villate, Tiange Lang, Isabelle Lesur, Christophe Boury, François Ehrenmann, Diana Zelenika, Anne Boland, Céline Besse, Pauline Garnier-Géré, Christophe Plomion & Antoine Kremer
An Illumina Infinium SNP genotyping array was constructed for European white oaks. Six individuals of Quercus petraea and Q. robur were considered for SNP discovery using both previously obtained Sanger sequences across 676 gene regions (1371 in vitro SNPs) and Roche 454 technology sequences from 5112 contigs (6542 putative in silico SNPs). The 7913 SNPs were genotyped across the six parental individuals, full-sib progenies (one within each species and two interspecific crosses between Q. petraea...

Data from: Local effects drive heterozygosity-fitness correlations in an outcrossing long-lived tree

Isabel Rodriguez-Quilon, Luis Santos-Del-Blanco, Delphine Grivet, Juan Pablo Jaramillo-Correa, Juan Majada, Giovanni Vendramin, Ricardo Alía & Santiago Gonzalez-Martinez
Heterozygosity-fitness correlations (HFCs) have been used to understand the complex interactions between inbreeding, genetic diversity and evolution. Although frequently reported for decades, evidence for HFCs was often based on underpowered studies or inappropriate methods, and hence their underlying mechanisms are still under debate. Here, we used 6,100 genome-wide Single Nucleotide Polymorphisms (SNPs) to test for general and local effect HFCs in maritime pine (Pinus pinaster Ait.), an iconic Mediterranean forest tree. Survival was used as...

Data from: RAD-sequencing reveals within-generation polygenic selection in response to anthropogenic organic and metal contamination in North Atlantic Eels

Martin Laporte, Scott A. Pavey, Clément Rougeux, Fabien Pierron, Hélène Budzinski, M. Lauzent, P. Labadie, E. Geneste, P. Couture, M. Baudrimont & L. Bernatchez
Measuring the effects of selection on the genome imposed by human-altered environment is currently a major goal in ecological genomics. Given the polygenic basis of most phenotypic traits, quantitative genetic theory predicts that selection is expected to cause subtle allelic changes among covarying loci rather than pronounced changes at few loci of large effects. The goal of this study was to test for the occurrence of polygenic selection in both North Atlantic eels (European Eel,...

Data from: Should the WHO growth charts be used in France?

Pauline Scherdel, Jérémie Botton, Marie-Françoise Rolland-Cachera, Juliane Léger, Fabienne Pelé, Pierre Yves Ancel, Chantal Simon, Katia Castetbon, Benoit Salanave, Hélène Thibault, Sandrine Lioret, Sandrine Péneau, Gaelle Gusto, Marie-Aline Charles & Barbara Heude
Background: Growth charts are an essential clinical tool for evaluating a child's health and development. The current French reference curves, published in 1979, have recently been challenged by the 2006 World Health Organization (WHO) growth charts. Objective: To evaluate and compare the growth of French children who were born between 1981 and 2007, with the WHO growth charts and the French reference curves currently used. Design: Anthropometric measurements from French children, who participated in 12...

Data from: Disentangling the heritable and plastic components of the competitive and facilitative effects of an alpine foundation species

Patrick Al Hayek, Jean-Paul Maalouf, Blaise Touzard & Richard Michalet
Differences in effects between phenotypes of foundation species on subordinate species have been reported, but no study has separated their heritable and plastic components. In a subalpine community of the French Pyrenees, we observed two phenotypes of Festuca gautieri: tight cushions in dry convex outcrops with few subordinate species, and loose cushions in wet concave slopes with many subordinate species, suggesting differences in effects of the two phenotypes on subordinates. Using two reciprocal transplantation gardens,...
