High incidence of dioecy in young successional tropical forests

, 2015
The role of plant sexual systems in community assembly has been little studied. Classical assumptions predict an association between self-fertilization and colonizing ability, a pattern not systematically supported by observations. Here, using a data set

Ecological Correlates with Dioecy in the Flora of a Tropical Premontane Wet Forest in Costa Rica. [PDF]

, 2017
There is a considerable disagreement about the selective forces that have led to the evolution of dioecy (i.e., the condition of having separate male and female flowers on separate plants).

Evolution of Dioecy and Sex Chromosomes in Willows [PDF]

My dissertation addresses several questions related to the evolution of sex chromosomes and separate sexes (dioecy) in different willow species. Sex chromosomes are known to evolve by recombination suppression between the X and Y (or Z and W) due to ...

Evolution of gynodioecy and dioecy: theoretical issues and the case of Bidens sandvicensis and B. cervicata

, 1993
Numerical models are shown to allow the spread of males into equilibrium nucleo-cytoplasmic populations, resulting in the evolution of subdioecy or dioecy.
