Differential phenotypic and genetic expression of defence compounds in a plant–herbivore interaction along elevation

Elevation gradients impose large differences in abiotic and biotic conditions over short distances, in turn, likely driving differences in gene expression more than would genetic variation per se, as natural selection and drift are less likely to fix alleles at such a narrow spatial scale. As elevation increases, the pressure exerted on plants by herbivores and on arthropod herbivores by...

Is hybridization driving the evolution of climatic niche in Alyssum montanum

PREMISE OF THE STUDY: After decades of interest, the contribution of hybridization to ecological diversification remains unclear. Hybridization is a potent source of novelty, but nascent hybrid lineages must overcome reproductive and ecological competition from their parental species. Here, we assess whether hybrid speciation is advantageous over alternative modes of speciation, by comparing...

Past climate‐driven range shifts and population genetic diversity in arctic plants

Pellissier, Loïc ; Eidesen, Pernille Bronken ; Ehrich, Dorothee ; Descombes, Patrice ; Schönswetter, Peter ; Tribsch, Andreas ; Westergaard, Kristine Bakke ; Alvarez, Nadir ; Guisan, Antoine ; Zimmermann, Niklaus E. ; Normand, Signe ; Vittoz, Pascal ; Luoto, Miska ; Damgaard, Christian ; Brochmann, Christian ; Wisz, Mary S. ; Alsos, Inger Greve

High intra-specific genetic diversity is necessary for species adaptation to novel environments under climate change, but species tracking suitable conditions are losing alleles through successive founder events during range shift. Here, we investigated the relationship between range shift since the Last Glacial Maximum (LGM) and extant population genetic diversity across multiple plant species...
