Greater reproductive assurance of asexual plant compared to sexual relative in a low density sympatric population – experimental evidence for pollen limitation

This dataset contains data from a common garden experiment described in the paper: “Mráz P, Mrázová V. 2021. Greater reproductive assurance of asexual plant compared to sexual relative in a low density sympatric population – experimental evidence for pollen limitation. Journal of Evolutionary Ecology ”. 

We compared the level and stability of reproductive assurance between sexual self-incompatible and asexual autonomously apomictic plants of Hieracium alpinum (Asteraceae) cultivated in a sympatric low-density population with two levels of spatial clumping of sexual plants. Overall, we found that the realized seed set (i.e. proportion of well developed seeds per capitulum) of asexuals was ca. 3-times greater than that of sexuals (83% versus 27%), while the variance of this trait expressed as coefficient of variation was ca. 4-times smaller in asexuals compared to sexuals (19% versus 83%). Solitary sexual plants had more than 2-times lower realized seed set when compared to clumps comp...
