Expelled by the Antarctic ice: Evolutionary history of the tribe Cunonieae (Cunoniaceae) Multiple fossil calibration points reveal recent radiations and biogeographical history of the Cunonieae tribe. The most densely sampled phylogeny allowed to infer Antarctica and Patagonia as areas o...

Our new study on Cunonieae (Cunoniaceae) shows the group originated ~56 Ma in Antarctica & Patagonia. As ice took over, they spread via Zealandia/Oceania & Patagonia, later diversifying in the Andes, Madagascar & New Caledonia.

Our efforts didn’t end in the field—we also came together for a Conservation Planning Workshop to share strategies and strengthen our collective work to protect Zamia species in the country.

Grateful to all who contributed their time and expertise.

Had a great week in the field with Vanessa Handley, Cristina Lopez, Mateo Roldán and Álvaro Pérez, looking for Zamia in Ecuador. This is a collaboration with the IUCN Cycad Specialist Group, the Global Conservation Consortium for Cycads, and the Ecuadorian Plant Specialist Group.
