Genetic sorting of subordinate species in grassland modulated by intraspecific variation in dominant species.

Genetic variation in a single species can have predictable and heritable effects on associated communities and ecosystem processes, however little is known about how genetic variation of a dominant species affects plant community assembly. We characterized the genetic structure of a dominant grass (...
