50 out of 2000 isn't really a bad or surprising number. Not only are the other turtles more abundant, but they are easier to see and capture. Which is why I also wonder about a blanket statement that proclaims Chrysemys and Chelydra as more abundant than Sternotherus. They are all much different...
Good lord! She is gorgeous! Very grateful that you shared the photos.
She looks young. I'd love to get updates on where she tops out, size-wise.
Good luck with her and thanks for sharing.

The ones that I kept and that Gerard bred were from the Congo. There is next to ZERO natural history information on these guys in English, anyway. I exhausted every bit of information, got my hands on pages from rare old books and everything. What you see in that article is just about everything...
This is a tough one. I agree with @CharlieM that it is probably Kinostern flavescens, the Yellow Mud Turtle. Keep in mind also, that the Eastern and Mississippi are the same species and are very similar animals.
