FIGURE 4 | Estimated mean dates for biogeographic events in Erythrinidae on tectonically active (Western) and passive (Eastern) continental margins. (A) Phylogenies of species in erythrinid genera from Figure 2A. Numbered circles represent biogeographic events dated using the geological literature (Table S3). Lettered tip labels represent biogeographic areas on the map. Red numbers at tree nodes represent mean divergence time esti- mates (Ma). (B) Lineage-age distribution of biogeographic events for clades in Panel A. Estimates are reported for minimum, median and maximum (mean dates from Figure 1) event age (Table S3). Ages of tectonic uplifts are indicated by horizontal rose bars. Note pulsed-age distribution of bio- geographic events in clades on the active Western margin, while the more continuous age distribution of events on the passive Eastern margin. Note opposite directions of watershed migration and geodispersal routes. Fish photographs: Hoplias and Erythrinus (Martin Taylor) and Hoplerythrinus (Jorge García-Melo)

If you missed the talk due to the recent daylight savings time switch, worry not! Sacek’s wonderful talk is now on Youtube. We are happy to help you reach him if you have questions.

Maybe one day I’ll get reviews from the paper I submitted in late December? 🫣

Exciting news!!!🎉 We are thrilled to announce the Keynote Speakers and the Schedule for the 2025 #SteepestDescentMeeting !!!🌍🏞

We are going to have exciting talks from
@aaronbufe.bsky.social, from LMU Munich, and Kimberly Huppert, from City College of New York (CCNY)!🤩 (1/2)

We’ve got a great line up! 🔥

Looking forward to interacting with all these great scientists over the coming months.

For geomorphologists going to EGU - registration is now open for Steepest Descent! This is an awesome 1/2 day meeting on the Sunday before EGU. Completely ECS community organized thanks to Jesse, Caroline, Rocio, Amanda, Jonah, Reha, and Emma!

Agree with this 100%. Reviewers should be acknowledged.

Unfortunately some journals also ask not to thank reviewers(!!)

Mobility of South America’s transcontinental drainage divide and shrinkage of the Paraná river basin linked to lithologic and geodynamic controls - Scientific Reports Scientific Reports - Mobility of South America’s transcontinental drainage divide and shrinkage of the Paraná river basin linked to lithologic and geodynamic controls

Happy to share the paper by my former MSc student from UFOP, Brazil. Congrats Caio!

Caio analyzed the underlying controls on the position and mobility of the transcontinental divide in South America.

Congrats to QC undegrad Adriana Zumba who also contributed!

Gotcha. Already a follower there! Cheers

Wow, looks like great weather! Do you share your photos somewhere? This is one of my favorite hikes I’ve ever done.

Snow, foliation, conjugate fractures in Central Park… cool!

😂

Let me test this super cool idea, it’ll just take 10 min (not!). It’s not like I have a week (with a weekend and a holiday in between) to submit final grades anyway. Ok ok, back to grading…

Very good point.

And it reminds me of something slightly macabre that a mentor once told me: papers won’t come to visit you when you’re on your death-bed…

Paper submitted. Again!
3rd time is a charm right?

Day 4 of #AGU24 is upon us! Don't forget to attend the Sharp Lecture this afternoon with @agunn.bsky.social at 4pm in Ballroom B!
#EPSPatAGU #AGWOO

Way to go Shane and Steve!

😂😂
AGU suggested I get to know @geomorphyuggs.bsky.social

We all have at least met before to some degree. I guess it goes to show that Geomorph is a friendly field in general? 🙂‍↔️

I wonder what other fields look like 🥶

Can’t wait to read this one

Not sure what is the consensus nor the beat tool, but the early career speaker at DELTA H this year, Helen Dias, gave a cool presentation on landslide identification through Object Based Image Analysis. Her paper is here:

Fine, fine. I made a starter pack for #EarthSurfaceProcesses and #geomorphologhy folks. 🧪⚒️ Am still adding folx but please let me know if you'd like to be added! go.bsky.app/CQzthwb

🌟@agu.org Fall Meeting go-ers, mark your calendars! Enjoy an evening filled with activities designed to help you share your science, spark conversations, meet your peers - participate in our poster bingo organized by @sz4grads.bsky.social -> register your poster: www.sz4d.org/events/sz4d-...

Such a cool idea! Is there a way to register without a poster?
