We investigated how plant species' responses to soil texture might affect coexistence by analysing distributions, seedling emergence and performance, and competitive abilities of the winter annuals Clarkia speciosa ssp. polyantha and C. xantiana ssp. xantiana.
Using field measurements, two common garden studies, and QST-FST analyses, we examined environmental and genetic influences on plant phenotype across the geographical range of Clarkia xantiana ssp. xantiana.
