Physiological performance and mating system in Clarkia (Onagraceae): does phenotypic selection predict divergence between sister species?

American journal of botany - 1 Mar 2012

Dudley Leah S, Hove Alisa A, Mazer Susan J

Abstract excerpt

PREMISE OF THE STUDY: The evolution of self-fertilization often occurs in association with other floral, life history, and fitness-related traits. A previous study found that field populations of Clarkia exilis (a predominantly autogamous selfer) and its sister species, Clarkia unguiculata (a facultative outcrosser) differ in mean photosynthetic rates and instantaneous water use efficiency (WUE(i)). Here, we...
