Arturo Gómez-Pompa Professor of Ecology and Botany in the Faculty of Sciences of the National University in the Institute of Biology at UNAM. These distinctive and academic positions have gained Gómez-Pompa a prestigious reputation in the ecological world. He discovered the use of Theobroma cacao, or the tree of chocolate, as ancient crops in rejolladas and cenotes within the Yucatán Peninsula. This confirmed his hypothesis on the anthropogenic origins of the Mayan forests and advanced future research in the domestication of tropical trees. Gómez-Pompa created a database for the Flora of Veracruz project in the 1960s that is still utilized to this
Cabécar people are among the tallest trees often found in Cabécar tropical home gardens. Lower strata include permanent crops such as coffee ("Coffea arabica") and cacao ("Theobroma cacao").
