Abstract. Biodiversity loss is proceeding at an unprecedented rate, yet we lack a thorough
understanding of the consequences of losing diversity at different scales. While species
diversity is known to impact community and ecosystem processes, genotypic diversity is
assumed to have relatively smaller effects. Nonetheless, a few recent studies suggest that
genotypic diversity may have quantitatively similar ecological consequences compared to
species diversity. Here we show that increasing either genotypic diversity of common evening
