Contrasting soil-texture niches facilitate coexistence of two congeneric plants that differ in competitive ability

Primary tabs

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.

description Whether close evolutionary relatives can coexist is expected to depend on evolutionary divergence in niches relative to divergence in competitive abilities. 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. A landscape survey showed that the species have distinct associations with soil texture, C. speciosa presence correlating with fne soil and C. xantiana correlating with coarse soil.
