Veronique Delesalle, Professor of Biology, with co-authors Susan J. Mazer (first author), Leah S. Dudley, Horacio Paz, and Preston Galusky, published "Stability of pollen-ovule ratios in pollinator-dependent versus autogamous Clarkia sister taxa: testing evolutionary predictions" in New Phytologist, Vol. 183 (2009): 630-648.  It has been proposed that natural selection should favor distinct temporal patterns of sex allocation in selfing vs pollinator-dependent taxa.  The authors' study provides partial support for the hypothesis that the pollen-ovule ratio is more stable in selfing than in outcrossing taxa and rejects the hypothesis that selfers are less stable.
