Abstract

The clusioid Glade comprises five monophyletic families: Bonnetiaceae, Calophyllaceae, Clusiaceae s.s., Hypericaceae, and Podostemaceae. Even though the circumscription of these families is well established, phylogenetic relationships within some families remain unresolved. This study aims to infer phylogenetic relationships within the Neotropical Calophylleae based on a broad sampling of taxa and a multilocus approach. We then use our phylogenetic framework as basis to investigate the evolution and biogeography of Calophylleae and diversification shifts in Calophyllaceae. To reconstruct the phylogeny of the Neotmpical Calophylleae, we used five plastid (matK, ndhF, rbcL, psbA-trnH, and trnK), two mitochondrial (matR and rps3), and two nuclear (EMB2765 and ITS) markers, including previously published and newly generated sequences. We sampled 74 species, increasing sampling of Neotropical taxa by 500%. Our phylogenetic hypothesis for Calophyllaceae provides additional support for the monophyly of all genera and allowed us to identify four main clades: Calophyllum, Kayea, Mammea, and the Neotropical Glade. The Neotropical Glade includes three main lineages, a small Glade composed of Clusiella and Marila, and a large HaCaKi Glade (i.e., Haplocarpa, Caraipa, and Kilmeyera) that is sister to Mahurea exstipulata. The evolution of three morphological traits (i.e., fleshy fruits, anther glands, and winged seeds) were shown to be associated with changes in evolutionary dynamics in Calophyllaceae, while a biome shift was detected in Kielmeyera, affecting net diversification within this genus. Major geological and climatic events such as the Andean uplift and a gradual decrease in temperatures seem to have influenced diversification rates within the Neotropical Calophylleae. (AU)
