Excavated from the Pisces Point locality of Scollard Formation in Alberta, Canada, ~67 million years old, Acronichthys maccognoi, newly reported in @science.org, was recovered from ancient water body that flipped seasonally between fast-flowing channels and quiet, still pools.

New in @science.org, meet Acronichthys maccagnoi, a new species from Late Creatacous Canada that changes what we know about the origins and evolution of one of the most successful fish groups on Earth.

Student’s life is not getting easier!
NSF today released instructions for the next round of applicants to its Graduate Research Fellowship Program. A key group—second-year Ph.D. students—is no longer eligible, and students who are still able to apply will face an unusually narrow timeframe. https://scim.ag/3KlQkQk
‘Completely shattered.’ Changes to NSF’s graduate student fellowship spur outcry
The announcement comes months later than usual, leaving many would-be applicants stranded

Fascinating catfish and a great report!
Make sure to turn on the sound when you play the video. You won’t regret it! 😉
Researchers have filmed thousands of climbing catfish scaling waterfalls, providing a rare insight into the daring migration of an enigmatic fish.

The remarkably similar-looking Noturus fish exhibit surprising variation in their Weberian ossicles, with significant associations to stem velocity and substrate type. This suggests that their auditory apparatus may adapt to specific microhabitats.

🎉 Published online today! 🐟 Thrilled to share FAM Lab PhD candidate Jennifer Hoeflich's thesis research! Using 3D GMM, she discovered that stream velocity & substrate influence ossicle morphology, suggesting acoustic adaptations to microhabitats. 🌊🪨🔬 #EcoMorphology #Ichthyology #Paleontology
