Data from: Ecology and evolution of the diaspore 'burial syndrome'

Aelys Muriel Humphreys, Alexandre Antonelli, Michael D. Pirie & H. Peter Linder
Hygroscopically active awns or "bristles" have long intrigued scientists. Experimental evidence shows that they are important for diaspore burial in the correct orientation, thereby increasing successful seed germination and seedling survival. Despite these ecological advantages, 38 of the 280 species of grasses in Danthonioideae lack awns. We provide the first study of awns in a phylogenetic context and show that whilst the awnless state has arisen ca. 25 times independently, the ecological disadvantage of not...
