Understanding the Geographic Patterns of Closely-Related Species of (Poaceae) Using Distribution Modelling and Seed Germination Traits.

The sexual species of the Dilatata complex (, , , and ) are closely related phylogenetically and show allopatric distributions, except . These species show microhabitat similarities and differences in germination traits. We integrated species distribution models (SDMs) and seed germination assays to determine whether germination divergences explain their biogeographic pattern.
