title: Variation and plasticity in life-history traits and fitness of wild Arabidopsis thaliana populations are not related to their genotypic and ecological diversity

description: Despite its implications for population dynamics and evolution, the
 relationship between genetic and phenotypic variation in wild populations
 remains unclear. Here, we estimated variation and plasticity in
 life-history traits and fitness of the annual plant Arabidopsis thaliana
 in two common garden experiments that differed in environmental
 conditions. We used up to 306 maternal inbred lines from six Iberian
 populations characterized by low and high genotypic (based on whole-genome
 sequences) and ecological (vegetation type) diversity. Low and
 high genotypic and ecological diversity was found in edge and core Iberian
 environments, respectively. Given that selection is expected to be
 stronger in edge environments and that ecological diversity may enhance
 both phenotypic variation and plasticity, we expected genotypic diversity
 to be positively associated with phenotypic variation and plasticity.
 However, maternal lines, irrespective of the genotypic and ecological
 diversity of their population of origin, exhibited a substantial amount of
 phenotypic variation and plasticity for all traits. Furthermore, all
 populations harbored maternal lines with canalization (robustness) or
 sensitivity in response to harsher environmental conditions in one of the
 two experiments. Overall, we conclude that the environmental
 attributes of each population probably determine their genotypic
 diversity, but all populations maintain substantial phenotypic variation
 and plasticity for all traits, which represents an asset to endure in
 changing environments.
