Investigador principal

Dr. Santiago Ramírez Barahona

Interested in the ecological, geographical, and historical factors that influence species and gene diversities at different spatial scales. My current research interests include the study of species responses to climate change in the cloud forest of Mesoamerica and the inference of macroevolutionary dynamics of vascular plants on a global scale.
