Sexual systems in gymnosperms: a review [PDF]
, 2018 The aim of this study was to update figures for the presence of dioecy among the gymnosperms and investigate its correlation with climate, growth form, pollination and seed dispersal syndromes, and risk of extinction.

Two in the bush: On the evolution, distribution and natural history of dioecy in Australian Solanum
, 2006 The causes, consequences, and correlates of dioecy have been the subject of much discussion since the days of Charles Darwin\u27s work. Several more recent authors have stressed the importance of informing this body of theory with studies that focus on ...

The evolution and maintenance of monoecy and dioecy in Sagittaria latifolia (Alismataceae)
, 2003 The evolution of separate sexes (dioecy) from combined sexes (hermaphroditism) is a central problem in evolutionary biology. Determining the conditions under which unisexual individuals replace individuals with two sexual pathways to reproductive fitness
