There are few genera of butterflies that feed on cycads. Among them the genus Eumaeus (Lycaenidae) presents aposematic coloration in all its life stages. In this work we report for the first time the herbivory of young leaflets of Ceratozamia mexican

Morphometric and geographical variation in theCeratozamia mexicanaBrongn. (Zamiaceae) complex: evolutionary and taxonomic implications

The Cycadales contain 11 nonproblematic genera and approximately 331 species where, in a number of cases, delimitation and circumscription is not so clear. Ceratozamia, the most diverse cycad genus in Mexico, clearly illustrates this situation becaus

La mayoría de las cícadas contienen altas concentraciones de aceites esenciales, flavonoides, polifenoles y polisacáridos que interfieren en la extracción de ADN, causando productos de amplificación errados o inhibiendo la PCR. La optimización
