Charles Darwin recognized that flowering plants have an unrivalled diversity of sexual
systems. Determining the ecological and genetic factors that govern sexual diversification in …

▪ Abstract Quantifying the extent to which seed production is limited by the availability of
pollen has been an area of intensive empirical study over the past few decades. Whereas …

▪ Abstract Mixed mating, in which hermaphrodite plant species reproduce by both self-and
cross-fertilization, presents a challenging problem for evolutionary biologists. Theory …

I present a phenotypic model of the selection of self-fertilization that applies to any mode of
selfpollination. A novel factor, seed discounting-the loss of outcrossing maternal fitness …

We conducted a comparative analysis to determine life history and ecological correlates of
pollen limitation among 224 species of animal-pollinated flowering plants. To test …

Most flowering plants are hermaphroditic, yet the proportion of seeds fertilized by self and
outcross pollen varies widely among species, ranging from predominant self-fertilization to …

Pollination commonly limits seed production, as addition of pollen to stigmas often increases
fecundity. This response is usually interpreted as evidence that plants' stigmas receive too …

A plant anatomy textbook unlike any other on the market today. Carol A. Peterson described
the first edition as' the best book on the subject of plant anatomy since the texts of Esau' …

Globally, plants display enormous variation in life‐history strategies and trait combinations.
However, evidence suggests that evolutionary and physiological constraints limit the …

In reward—producing animal—pollinated plants, small populations are likely to be less
attractive to pollinators than large populations. The likelihood of pollinator limitation of seed …
