Figure 3 - The role of hummingbirds in the evolution and diversification of Bromeliaceae: unsupported claims and untested hypotheses

Ancestral pollinator state reconstruction for the Vriesea radiation from the Atlantic Rainforests of eastern Brazil showing repeated shifts between bat and hummingbird pollination. For this analysis, we used the phylogenetic tree of Gomes-da-Silva & Souza-Chies (2018) and collected information of pollinator groups from the literature for >50% of the species (for references see Supporting Information, Table S1). For species lacking pollinator information, we applied the concept of pollination syndromes based on floral morphology (Fӕgri & van der Pijl 1979). We categorized groups either as hummingbird-, hummingbird-/bat-or bat-pollinated and reconstructed ancestral pollinator states applying a Bayesian Markov chain Monte Carlo (MCMC) analysis in RASP version2.1 beta (Yu, Harris & He, 2012). Using the Jukes-Cantor + G model, sampling each of 100 generations, we ran the MCMC analysis for 50 000 generations and allowed all character combinations. We chose the MCMC approach because it offers the opportunity to code hummingbird/bat pollination as an intermediate stage.
