Floral traits influence the opportunity for selection among male gametophytes: independent and combined effects of style length and petal area

The data set included here was used for the analyses published in a paper titled, \" American Journal of Botany, for which the abstract is as follows:

PREMISE: Strong correlations between traits can obscure their independent effects on components of reproduction.  Style length (SL) and petal area (PA) vary within species, for example, but their independent effects on the opportunity for selection among pollen genotypes are poorly understood. Previous work in Clarkia detected a positive effect of SL on pollen receipt, potentially intensifying selection.  However, this apparent effect of SL may be influenced by a correlated trait, such as PA. Here, we examine the independent effects of these two traits on pollen receipt and performance.

 

METHODS: We collected petals and styles from wild populations of two insect-pollinated Clarkia taxa and estimated the independent and combined effects of SL and PA on pollen receipt and performance.

 

RESULTS:  In both taxa, SL and PA are p...
