Data from: Jack of all nectars, master of most: DNA methylation and the epigenetic basis of niche width in a flower-living yeast

Carlos M. Herrera, María I. Pozo & Pilar Bazaga
In addition to genetic differences between individuals due to nucleotide sequence variation, epigenetic changes experienced by genotypes due to DNA methylation may also contribute to population niche width, an intriguing possibility that remains essentially untested. Using the nectar-living yeast Metschnikowia reukaufii as study subject, we examine the hypothesis that changes in genome-wide DNA methylation patterns underly the ability of this fugitive species to exploit a broad resource range in its heterogeneous patchy environment. Data on...

Data from: Temporal variation in genetic diversity and effective population size of Mediterranean and subalpine Arabidopsis thaliana populations

Nasr H. Gomaa, Alicia Montesinos-Navarro, Carlos Alonso-Blanco & F. Xavier Picó
Currently there exists a limited knowledge on the extent of temporal variation in population genetic parameters of natural populations. Here we study the extent of temporal variation in population genetics by genotyping 151 genome-wide SNP markers polymorphic in 466 individuals collected from nine populations of the annual plant Arabidopsis thaliana during four years. Populations are located along an altitudinal climatic gradient from Mediterranean to subalpine environments in NE Spain, which has been shown to influence...

Data from: Clonality, genetic diversity, and support for the diversifying selection hypothesis, in natural populations of a flower-living yeast

Carlos M. Herrera, María I. Pozo & Pilar Bazaga
Vast amounts of effort have been devoted to investigate patterns of genetic diversity and structuring in plants and animals, but similar information is scarce for organisms of other kingdoms. The study of the genetic structure of natural populations of wild yeasts can provide insights on the ecological and genetic correlates of clonality, and on the generality of recent hypotheses postulating that microbial populations lack the potential for genetic divergence and allopatric speciation. Ninety-one isolates of...
