And here’s Julie’s answer to who is more stressed, a girl tuco-tuco in a group or alone?

I promised to tell you what I’ve been finding out with stress hormones in tuco-tucos. As it turns out, females that live alone to raise their pups usually have higher baseline corticosterone (stress hormones) than females that live in groups.

Having higher baseline levels means that it requires a bit more energy for a female to do it all alone. Female tuco-tucos that live alone still do well as far as having babies are concerned. However, they don’t live as long as females that live in groups. I don’t know if this is because they have to use more energy but it could be.

I am also looking at differences found in the females that live in groups and whether some have higher stress levels than others. That is still a work in progress.

Congratulations to both scubagirl and StarGrace for giving the correct answer to Julie’s STEM challenge question!  We will have a drawing to see who gets a STEM T-shirt.

iTwixie’s BFF, Julie, is a graduate student at the University of California, Berkeley. She is returning there from her field work on tuco-tucos. We will be learning what she can do with the tuco-tucos she is raising in her lab.
