Growth, mortality, and mating group size of an androdioecious
barnacle: implications for the evolution of dwarf males.
Mixed genetic and environmental sex determination in an androdioecious
population of Mercurialis annua.
To test whether the hermaphrodite and male sexes are fixed or plastic in the androdioecious pedunculate barnacle Octolasmis warwickii, we conducted a series of 22-day-long transplanting experiments to evaluate the effects of a) the original site (attached to the conspecific vs.
In both dioecious and androdioecious barnacles, males are always tiny and live attached to conspecific females or hermaphrodites; hence, they are known as dwarf males (see Hoeg, 1995 and Yusa et al.
Phylogenetic reconstruction of the neotropical family Quiinaceae (Malpighiales) based on morphology with remarks on the evolution of androdioecious
warwickii is similar to that of androdioecious
species such as Scalpellum scalpellum or Koleolepas avis, in both of which about 20% of hermaphrodites had no neighbors (Svane, 1986; Yusa et al.
