Happy to share our most recent paper: a complete inventory of non-native vascular plants in continental Ecuador: 486 taxa. Mostly herbs (67%) from Asia & Africa. 93% found in the Andes. 80% have known uses—ornamental (42%), medicinal (38%). neobiota.pensoft.net/article/1472...

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.

Happy to share our new publication on the phylogeny of Weinmannia. A great example of how the rise of the Andes created new environments that allow the evolution of new plant species. Want to learn more? Your personalized Share Link:

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.
