Intraspecific competitive interactions rapidly evolve via spontaneous mutations

Using a mechanistic spatially explicit trait-based neighborhood-model, we quantify the impact of mutations on intraspecific spatial interactions to better understand mechanisms underlying maintenance genetic variation and potential effects these evolved population dynamics Arabidopsis thaliana. We use 100 twenty-fifth generation mutation accumulation (MA) lines (genotypes) derived from one founder genotype study mutational neighbor responses in field experiment. created individual-based maps (15,000 individuals), including phenotypic variation, within genotypes versus between reproduction survival. At small-scale (within 80 cm focal plant), survival is enhanced but seed-set decreased when surrounded by different genotypes. large-scale 200 seed set facilitated while same has either no effect or negative effects. The direction among MA suggests that at small scale may contribute large population. This suggest, that, potentially have immediate community influencing outcome competitive faciliatory conspecifics.
