Estimates of inbreeding depression obtained from the literature were used to evaluate the
association between inbreeding depression and the degree of self‐fertilization in natural …

Cleistogamy—the production of open (chasmogamous—CH) and closed (cleistogamous—
CL) floral forms by a species—is widespread among the angiosperms. While the CL flower …

Many functional-ecological, morphological, and physiological-factors affect the occurrence
of selffertilization. Six modes of self-pollination are distinguished. These differ in whether …

A bimodal distribution of outcrossing rates was observed for natural plant populations, with
more primarily selfing and primarily outcrossing species, and fewer species with …

It is postulated that in one reproductive session the level of maternal expenditure of an
angiosperm plant is determined by a temporal series of controls on the number of potential …

interaction of plant reproductive mechanisms in relation to ecological factors are entitled (1) …

I develop a model of the ecology and evolution of seed heteromorphism. Heteromorphism is
promoted over monomorphism by low correlation of the demographic success of the …

Floral nectar production is central to plant pollination, and hence to human wellbeing. As
floral nectar is essentially a solution in water of various sugars, it is likely a valuable plant …
