Size-dependent sex allocation in Solanum lycocarpum St. Hil. (Solanaceae)
Resource allocation to reproduction can change depending on size, as predicted by the size-dependent sex allocation. This theory is based on the fact that small individuals will invest in the allocation of sex with lower cost of production, usually male ...

The optimal life history and sex allocation of perennial hermaphrodites should depend on both their size and the relative costs and benefits of reproducing through male versus female functions.

Reproductive biology of the andromonoecious Cucumis melo subsp. agrestis (Cucurbitaceae) [PDF]
Cucumis melo subsp. agrestis (Cucurbitaceae) is cultivated in many African regions for its edible kernels used as a soup thickener. The plant, an annual, andromonoecious, trailing-vine species, is of high social, cultural and economic value for local communities.

Sexual systems in the New Zealand angiosperm flora
ABSTRACT We present data on sexual systems and associated traits in the New Zealand angiosperm flora and discuss reasons for the anomalously high levels of gender dimorphism in the flora, and the low levels of monoecy in woody species. Along with Hawai'i and New Caledonia, New Zealand has exceptionally high levels of gender dimorphism (19.5% of ...

Adaptive function of duodichogamy: Why do chestnut trees have two pollen emission phases?
Abstract Premise Intersexual mating facilitation in flowering plants has been largely underexplored. Duodichogamy is a rare flowering system in which individual plants flower in the sequence male‐female‐male. We studied the adaptive advantages of this flowering system using chestnuts (Castanea spp., Fagaceae) as models.

Reproductive biology of the andromonoecious shrubTrevoa quinquenervia(Rhamnaceae) [PDF]
Abstract Various aspects of the reproductive biology of the andromonoecious shrub Trevoa quinquenervia Gill. & Hook. were studied in a population located in central Chile. Flowering extends from mid August to the end of December. The small, white, entomophilous flowers are incompletely protandrous and last c . 5 days.

Differential reward in “male” versus “female” pollen of functionally dioecious Solanum
Abstract Premise Five to six percent of angiosperm species exhibit a dioecious sexual system, with unisexual “male” or “female” flowers borne on separate plants. The consequent need for inter‐individual pollen exchange is a special challenge for taxa where pollen is the sole pollinator reward.

Dichogamy and Sexual Dimorphism in Floral Traits in the Andromonoecious Euphorbia boetica [PDF]
Euphorbia boetica (Euphorbiaceae) is a functional andromonoecious species that shows both intra- and interfloral dichogamy, hermaphrodite cyathia being protogynous. Sexual dimorphism of the cyathia of E. boetica is examined according to their gender and arrangement on the inflorescence.Data were obtained from two natural populations, where the ...

Abstract Targeted capture of nuclear genes increasingly contributes to unravelling phylogenetic relationships that hitherto remained unresolved because of limitations of traditional Sanger sequencing. In particular, the study of tropical plant families has been compromised because they often rely on highly degraded DNA obtained from herbarium specimens.
