Untangling a species complex of arid zone grasses (Triodia) reveals patterns congruent with co-occurring animals
Abstract
We delimit taxa in a species complex of grasses using morphology and molecular markers. Geographic partitioning of genetic lineages is congruent with ranges of co-occurring animals. Greater lineage diversity and endemism in the Pilbara are consistent with it being a refugium. Individuals with ITS copies from different taxa suggest hybridization.
