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.
Using comprehensive demographic data for two well-studied, short-lived plants (Plantago coronopus, Clarkia xantiana), we show that the arrangement of species' demographic niches reveals key features of their environmental niches and geographic distributions.
