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

Somatic mutations are common in plants, and they may accumulate and be passed on to
gametes. The determinants of somatic mutation accumulation include the intraorganismal …

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 …

The adaptive significance of different types of inflorescences in flowering plants has been
largely ignored. The few published studies investigating adaptive aspects of floral displays …

The likelihood that dioecy could evolve via androdioecy is examined. It is concluded that
female-sterility mutations are unlikely to be able to invade populations of self-compatible …

Animals and plants that change sex during their lives are widely distributed geographically
and taxonomically but are a minority of sexual organisms. Recent theory relating to the …

The range of environmental sex determination and sex changes throughout plant taxa from
bryophytes and pteridophytes to spermatophytes is reviewed. Lability in sex expression …

Since Darwin's time and the publication of The Different Forms of Flowers on Plants of the
Same Species (1877), there has been continuing interest in understanding the complex but …

A fundamental problem in plant population biology and evolutionary ecology is determining
the extent to which natural selection changes the gene pool of populations in the wild. While …

Despite the extensive research on the potential benefits of dioecy to individuals, little is
known about the long-term success of dioecious lineages in relation to their hermaphroditic …
