Abstract: Considerable effort has been spent documenting correlations between dioecy and various ecological and morphological traits for the purpose of testing hypotheses about conditions that favor dioecy. The data analyzed in these studies, with few exceptions, come from local floras, within which it was possible to contrast the subsets of dioecious and nondioecious taxa with regard to the traits in question. However, if there is a strong phylogenetic component to the presence or absence of dioecy, regional sampling m… Show more

“…In addition, our finding that dioecious species tended to have few, large seeds per fruit and very small flowers, and to have biotic dispersal and abiotic pollination, is in accordance with the results of, for instance Bullock (1994), Ibarra-Manríquez & Oyama (1992) and Renner & Ricklefs (1995). We also confirmed the tendency for the female flowers to be solitary.…”

“…A dioicia é um sistema sexual caracterizado pela presença em uma população de indivíduos, que produzem flores exclusivamente estaminadas ou pistiladas (GEBER et al, 1999) e está distribuída em cerca 6% das espécies de angiospermas de regiões tropicais (RENNER;RICKLEFS, 1995). A razão sexual em plantas dióicas é geralmente próxima de 1:1, mas diferenças significativas em favor de um ou outro sexo são frequentemente observadas em taxa de dióicos tropicais (OPLER;BAWA, 1978).…”

“…A família Anacardiaceae ocorre principalmente em regiões tropicais e subtropicais (Heywood 1985), sendo predominantemente representada por espécies dióicas (Bullock 1985, Ibarra-Manríquez & Oyama 1992, Renner & Ricklefs 1995. Tapirira guianensis Aubl.…”
