On Growth and Form: Ecology and Evolution of Columnar Cacti

March 28 @ 7:00 pm - 8:30 pm


Join the NHI and world-renowned researcher Dr. Alberto Burquez for this free presentation on giant columnar cacti, including Arizona’s iconic saguaros.

There are over 100 species of columnar cacti found throughout Central and South America, the largest and greatest variety of which are found in Mexico. Just three species grow natively as far north as Arizona – organ pipe cacti, senitas, and of course, the beloved saguaros. In this talk, columnar cacti ecologist Dr. Alberto Burquez will detail his research on the evolutionary history and ecology of these massive charismatic plants, with special focus on the saguaros. He will explain their adaptations to life in the Sonoran Desert, their taxonomic relationships, how their range has changed over time, and the effects climate change will have on them.

Alberto Búrquez, Ph.D., is a researcher at the Instituto de Ecología at the Universidad Nacional Autónoma de México. He is a co-author (with David Yetman) of The Saguaro Cactus: A Natural History and Mexico’s Valleys of Cuicatlán and Tehuacán: From Deserts to Clouds. His scientific papers on ecology, evolutionary biology, and ethnoecology have been cited over 8,000 times. His current work focuses on population ecology and genetics of columnar cacti, plant-animal relationships, biogeography, ecology of invasion by plants, and land-use change in the Sonoran Desert and the tropical deciduous forests of the Pacific coast of Mexico.
