‘Dispersification’ of Agalinis (Orobanchaceae) Into South America Is Associated With Hummingbird Pollination and Perennial Life‐History Shifts

Journal of Biogeography, Volume 53, Issue 1, January 2026.
ABSTRACT Aim Several mechanisms contribute to the plant biodiversity of the Neotropics, with the highlands of South America serving as important hotspots of diversity. In particular, the Brazilian highlands exhibit high biodiversity due to complex diversification dynamics and a mixture of contributions from different biomes.
