Data from: Extending the use of ecological models without sacrificing details: a generic and parsimonious meta-modelling approach

Guillaume Marie & Guillaume Simioni
Process-based models (PBMs, see table 1 for a list of abbreviations) are essential tools to assess ecosystem response to climate change, land use changes, extreme weather patterns, or other environmental disturbances. PBMs allow to deal with the high level of interactions and feedbacks which are intrinsic to ecological processes, but their complexity comes at the cost of computation time and memory. Because of that, there is a trade-off between the resolution satisfactory to describe ecological...

Data from: Simulating local adaptation to climate of forest trees with a Physio-Demo-Genetics model

Sylvie Oddou-Muratorio & Hendrik Davi
One challenge of evolutionary ecology is to predict the rate and mechanisms of population adaptation to environmental variations. The variations in most life history traits are shaped both by individual genotypic and by environmental variation. Forest trees exhibit high levels of genetic diversity, large population sizes, and gene flow, and they also show a high level of plasticity for life history traits. We developed a new Physio-Demo-Genetics model (denoted PDG) coupling (i) a physiological module...

Data from: Contrasted invasion processes imprint the genetic structure of an invasive scale insect across southern Europe

Carole Kerdelhué, Thomas Boivin & Christian Burban
Deciphering the colonization processes by which introduced pests invade new areas is essential to limit the risk of further expansion and/or multiple introductions. We here studied the invasion history of the maritime pine bast scale Matsucoccus feytaudi. This host-specific insect does not cause any damage in its native area, but it devastated maritime pine forests of South-Eastern France where it was detected in the 1960s, and since then reached Italy and Corsica. We used population...

Data from: Linking niche theory to ecological impacts of successful invaders: insights from resource fluctuation-specialist herbivore interactions

Cindy Gidoin, Lionel Roques & Thomas Boivin
1. Theories of species coexistence and invasion ecology are fundamentally connected and provide a common theoretical framework for studying the mechanisms underlying successful invasions and their ecological impacts. Temporal fluctuations in resource availability and differences in life-history traits between invasive and resident species are considered as likely drivers of the dynamics of invaded communities. Current critical issues in invasion ecology thus relate to the extent to which such mechanisms influence coexistence between invasive and resident...

Data from: Genomic exploration and molecular marker development in a large and complex conifer genome using RADseq and mRNAseq

Marie-Joe Karam, François Lefèvre, Magda Bou Dagher-Kharrat, Sara Pinosio & Giovanni Vendramin
We combined restriction site associated DNA sequencing (RADseq) using a hypomethylation-sensitive enzyme and messenger RNA sequencing (mRNAseq) to develop molecular markers for the 16 gigabase genome of Cedrus atlantica, a conifer tree species. With each method, Illumina® reads from one individual were used to generate de novo assemblies. SNPs from the RADseq data set were detected in a panel of one single individual and three pools of three individuals each. We developed a flexible script...

Data from: Genetic structure and diversity of the endangered fir tree of Lebanon (Abies cilicica Carr.): implications for conservation

Lara Awad, Bruno Fady, Carla Khater, Anne Roig & Rachid Cheddadi
The threatened conifer Abies cilicica currently persists in Lebanon in geographically isolated forest patches. The impact of demographic and evolutionary processes on population genetic diversity and structure were assessed using 10 nuclear microsatellite loci. All remnant 15 local populations revealed a low genetic variation but a high recent effective population size. FST-based measures of population genetic differentiation revealed a low spatial genetic structure, but Bayesian analysis of population structure identified a significant Northeast-Southwest population structure....
