Geographical distribution of dioecy and its ecological correlates based on fine‐scaled species distribution data from a subtropical island

Dioecy is a rather rare sexual expression system guarantees outcrossing to avoid the deleterious effects of inbreeding. The incidence of dioecy varied among local floras and suggested inclining to tropical and oceanic environments, but its eco‐correlates received little research attention. In this article, we explored geographical patterns and variations in sexual expression systems of angiosperms in mountainous environments of Taiwan, a...
