Plant evolution in the tropics: examples from the African Annonaceae and the Andean Melastomataceae

Plant evolution is under the influence of several biotic and abiotic drivers. Here I will present insights in the plant evolution of two major tropical plant clades, in two different geographical
settings: the Monodoreae tribe (Annonaceae) of Africa and the Merianieae tribe (Melastomataceae) of South America. The evolutionary relationships within the two clades were inferred with a phylogenomic approach, and biogeographic and macroevolutionary analyses were conducted. The Monodoreae (ca. 90 species) evolved in the past 25 Myrs in the tropical rain forests of Africa. They experienced several range contraction and expansion, as well as a sudden extinction event. Birth-death models suggest that African elevation change (orogeny) is positively linked to speciation in this clade. The Merianieae (ca. 300 species) originated around 30 Myrs ago in South America. The Andes seems to have played an important role in promoting a fast diversification, leading to important uncertainty in evolutionary relationships (many reconstructed branches are poorly supported). Morphological character evolution is also interesting in this clade, and could be linked with pollinator shift in the Andes. I will also discuss how plant evolution is complex, and how reticulate evolution can impact analyses and bring uncertainty.
