Diversification of Dioon in the Mexican transition zone
The Mexican transition zone originated from the overlap of the Nearctic and the Neotropical biotas. By analysing the genetic variation within the cycad genus Dioon, a relict Neotropical group, Gutiérrez-Ortega et al...

Aridification as driver of plant evolution
Aridification has been a major force in cycad evolution, says José Said Gutiérrez-Ortega. It helps to explain why cycads were capable to adapt and diversify in the modern habitats, even when they originated in the early...

Plants and Pinatubo, Prestahnukur, Popocatépetl…
Plants are generally sessile organisms that, unlike their puny animal ‘cousins’, can’t get up and run away if the environment is not to their liking. Botanicals by-and-large put up and shut up. Accordingly, that...

A stable phylogeny for the cycads
The cycads (order Cycadales) are an ancient order of gymnosperms comprising ten genera and 331 species found in all tropical regions of the earth. Using sequences of five single copy nuclear genes, Salas-Leiva et al...
