dioecious

Patterns of phenological variation and reproductive investment were studied in the 'dioecious' shrub Baccharis dracunculifolia DC, and possible consequences on survivorship were evaluated.

Consider a population of 'dioecious' species, in which males mate randomly with females.

We compared the phyllotaxy and characteristics of the vascular system for two of the 'dioecious' species (subgenus Acnida).

Lloyd and Webb suggested that if females of 'dioecious' species allocated a greater proportion of their available energy to reproduction than males, then females should be slower growing and have lower survival rates.

The worms are 'dioecious' , with the female laying about 300 eggs/day.

S. latifolia has recently become a popular model to study 'dioecy' and evolution of plant sex chromosomes.

In addition, the general term ‘population structure’ encompasses 'dioecy' , ploidy level, age structure, reproductive patterns such as partial selfing, as well as the various forms of geographical structure and dispersal.

If this classification reflects the phylogeny of the genus, it implies that 'dioecy' has appeared several times over the evolution of Rumex species directly from a hermaphroditic ancestor.

Sagittaria is one such taxon enabling studies of the evolution of 'dioecy' from monoecy.

Further information is necessary to test whether the dioecious species of Amaranthus are actually not a natural group and whether 'dioecy' evolved more than once in the genus.
