Data from: Stable epigenetic effects impact adaptation in allopolyploid orchids (Dactylorhiza: Orchidaceae)

Ovidiu Paun, Richard M. Bateman, Michael F. Fay, Mikael Hedrén, Laure Civeyrel & Mark W. Chase
Epigenetic information includes heritable signals that modulate gene expression but are not encoded in the primary nucleotide sequence. We have studied natural epigenetic variation in three allotetraploid sibling orchid species that differ radically in geography/ecology. The epigenetic variation released by genome doubling has been restructured in species-specific patterns that reflect their recent evolutionary history, and have an impact on their ecology and evolution, hundreds of generations after their formation. Epigenome scans pinpointed epiloci under divergent...

Data from: The relevance of gene flow in metapopulation dynamics of an oceanic island endemic, Olea europaea subsp guanchica

Carlos García-Verdugo, Alan D Forrest, Michael F Fay & Pablo Vargas
Theoretical and empirical studies suggest that geographical isolation and extinction-recolonization dynamics are two factors causing strong genetic structure in metapopulations. Here, we investigated the effect of population age structure and isolation by distance in the patterns of genetic diversity in a tree species (Olea europaea subsp. guanchica) sporadically affected by volcanic events across the Canarian archipelago. Genetic variation was assessed at six nuclear microsatellites (nDNA) and six chloroplast fragments (cpDNA) in nine subpopulations sampled on...

Data from: Historical divergence versus contemporary gene flow: evolutionary history of the calcicole Ranunculus alpestris group (Ranunculaceae) in the European Alps and the Carpathians

Peter Schönswetter, Andreas Tribsch, Ovidiu Paun & Manuela Winkler
Although many species have similar total distributional ranges, they might be restricted to very different habitats and might have different phylogeographic histories. In the European Alps, our excellent knowledge of the evolutionary history of silicate-dwelling plants is contrasted by a virtual lack of data from limestone-dwelling plants. These two categories are expected to differ strongly with respect to their glacial history. The calcicole Ranunculus alpestris group comprises three diploid species of alpine habitats. Analyses of...

Data from: Towards a worldwide wood economics spectrum

Amy E. Zanne, G. Lopez-Gonzalez, David A. Coomes, Jugo Ilic, Steven Jansen, Simon L. Lewis, Regis B. Miller, Nathan G. Swenson, Michael C. Wiemann & Jerome Chave
Wood performs several essential functions in plants, including mechanically supporting aboveground tissue, storing water and other resources, and transporting sap. Woody tissues are likely to face physiological, structural and defensive trade-offs. How a plant optimizes among these competing functions can have major ecological implications, which have been under-appreciated by ecologists compared to the focus they have given to leaf function. To draw together our current understanding of wood function, we identify and collate data on...
