Biogeography shaped the metabolome of the genus Espeletia: a phytochemical perspective on an Andean adaptive radiation

Abstract The páramo ecosystem has the highest rate of diversification across plant lineages on earth, of which the genus Espeletia (Asteraceae) is a prime example. The current distribution and molecular phylogeny of Espeletia suggest the influence of Andean geography and past climatic fluctuations o...
