In conservation strategies, getting precise and repeatable information on the species’ diet and health without relying on invasive or laborious methods is challenging. Here, we developed an efficient and non-invasive workflow for the sequencing and analysis of four taxonomic markers from fecal DNA to characterize the gut microbiota, parasites, and...

Le mélèze laricin, ou Larix laricina de son nom latin, est le seul représentant indigène de son genre au Canada. Sa capacité à croître dans une large gamme d’environnements fait en sorte qu’on le trouve bien réparti sur le territoire. Espèce pionnière intolérante à l’ombre, elle résiste bien, à contrario, aux inondations. Aujourd’hui, on s’intéress...

Research highlights: To understand differences in the establishment of balsam fir regeneration observed in the boreal forest, we examined how soil layer and microorganisms explained differences in growth and mycorrhization in three different stand types. Our experiment revealed positive and negative effects on growth of seedlings, and highlights th...

Au Québec, le 49° de latitude nord représente la frontière entre d'une part la forêt mixte dominée par le sapin baumier et le bouleau et d'autre par la forêt boréale dominée par l'épinette noire. Cette frontière tend à migrer vers le nord avec la migration du sapin. Dans les plaines argileuses de l'Abitibi-Témiscamingue qui se trouvent à cette lati...

Succession is generally well described above-ground in the boreal forest, and several studies have demonstrated the role of interspecific facilitation in tree species establishment. However, the role of mycorrhizal communities for tree establishment and interspecific facilitation, has been little explored. At the ecotone between the mixed boreal fo...

Aims While fungi are key drivers of the carbon cycle and obligate symbionts of trees, the link between plant-fungal interactions and landscape vegetation changes has been largely overlooked. Our aim was to test whether a local difference in dominant tree species would shape the composition of soil fungi communities. Methods Fungal communities were...

We investigated whether the diversity, endemicity and specificity of alder symbionts could be changed by isolation in a Mediterranean glacial refugium. We studied both ectomycorrhizal (EM) fungi and nitrogen‐fixing actinobacteria associated with alders, and compared their communities in Corsica and on the European continent. Nodules and root tips w...

Background Recent climatic history has strongly impacted plant populations, but little is known about its effect on microbes. Alders, which host few and specific symbionts, have high genetic diversity in glacial refugia. Here, we tested the prediction that communities of root symbionts survived in refugia with their host populations. We expected to...
