UV radiation linked to mass extinction!

Recent research into the chemistry of ancient pollen grains has revealed a pulse of elevated UV radiation may have played a role in the end Permian mass extinction event (250 million years ago). To find out more:

APD Workshop Series: R, Databases, and You!

January 17, 2023
sji15

Interested in African paleoecology? Want to incorporate African pollen data into your research or teaching?

If you read nothing else, please take this survey before January 25!

The African Pollen Database (APD) has been relaunched, and the Neotoma Paleoecology Database now contains over 200 APD records. Data stewards working with APD and Neotoma have been meeting regularly for the last two years to upload data, but we are now changing the format of our meetings in order to start focusing on helping people use APD data for research and teaching!

We are developing a schedule of practical tutorials on APD data workflows in R, using Rneotoma, and a few other topics to take place over next few months (see this video for general info).

This is open to anyone interested in African paleoecology (students, researchers, teachers, etc)! If you or your students might be interested in taking part in one or all of these, please take this very brief survey by January 25 to let us know. Also if you have other students or researchers you think should get this email, let Sarah Ivory (sji15@psu.edu) or Chris Kiahtipes (chris.kiahtipes@gmail.com) know.
