Aim We reconstructed the biogeographic history of Pappophorinae and tested whether the evolution of awns is associated with differences in species' geographic ranges. Location Americas. Time Period Miocene. Major Taxa Studies Pappophorinae (Poaceae: Chloridoideae). Methods We recovered a time‐calibrated phylogeny and detected a phylogenetic signal between awn length and number and the species extent of occurrence (EOO). Result...

Aim We investigate the evolutionary mechanisms that allow morphologically convergent lineages to share the same geographical space. We compared the evolutionary events that occurred along the diversification of Karawata and Aechmea subgen. Chevaliera in the Atlantic Forest by (a) verifying whether the climatic niches and habitats of Karawata and Chevaliera are similar; (b) testing whether the two groups had the same pattern of...
