Pollination and plant reproduction in the Cerrado, the world's most biodiverse savanna. [PDF]
Biol Rev Camb Philos SocABSTRACT The Brazilian Cerrado is a continental‐wide biodiversity hotspot and the most species‐rich savanna ecosystem in the world. The main aspect characterising this biodiversity is that the landscape is arranged as an intricate mosaic of different plant formations, including grasslands, savannas, and forests, each harbouring distinct but ...

Ecological Processes, 2021 Background The expression of gender in gymnosperms is challenging because the extent of variability in gender segregations in tree crowns and selection pressure of nature can modify the gender through time.

Scientific Reports, 2021 Castor (Ricinus communis L) is an ideal model species for sex mechanism studies in monoecious angiosperms, due to wide variations in sex expression. Sex reversion to monoecy in pistillate lines, along with labile sex expression, negatively influences ...

Influence of Environment on the Floral Sex Ratio of Monoecious Plants [PDF]
Evolution, 1981 Both theoretical and empirical data suggest that sessile, simultaneous hermaphroditic individuals growing in patchy environments may experience unequal reproductive success via male and female gametes depending on whether they occupy favorable or marginal sites (Schaffner, 1935; Heslop-Harrison, 1972; Freeman et al., 1976, 1980; Charnov and Bull, 1977;

Inflorescences of Cliffortia L. (Rosaceae) and related vegetative branching patterns
Bothalia: African Biodiversity & Conservation, 2003 The inflorescence construction of eight species, representative of the types found in the 119 species of the rosaceous genus Cliffortia L. is described, based on stereo microscopic examination of fresh and dried specimens, combined with extensive field ...

Monoicy, dioicy, and genetic structure in three species of Sheathia (Batrachospermales, Rhodophyta). [PDF]
J PhycolAbstract Sexual systems (i.e., separate vs. combined sexes) vary widely among eukaryotes and influence the evolution of reproductive systems, which shape genetic structure and evolutionary trajectories. In diploid‐dominant angiosperms, combined (i.e., hermaphroditism) and separate sexes are expected to correlate with selfing and outcrossing ...

The incidence and pattern of copollinator diversification in dioecious and monoecious figs [PDF]
Evolution, 2015 Differences in breeding system are associated with correlated ecological and morphological changes in plants. In Ficus, dioecy and monoecy are strongly associated with different suites of traits (tree height, population density, fruiting frequency, pollinator dispersal ecology).

Frontiers in Plant Science, 2020 Plant sexual systems play an important role in the evolution of angiosperm diversity. However, large-scale patterns in the frequencies of sexual systems (i.e. dioecy, monoecy, and hermaphroditism) and their drivers for species with different growth forms

Frontiers in Plant Science, 2020 The mechanism behind the bud evolution towards breba or main crop in Ficus carica L. is uncertain. Anatomical and genetic studies may put a light on the possible similarities/differences between the two types of fruits.
