Those aren't particularly new things to study. We have tons of murine data on the subject and quite a few PhD students over the last 4-6 years have done their PhDs on microbiota and diet with themselves as the guinea pig, so to speak (2-4 year longitudinals).

There are a couple mouse papers out that don't directly address the issue in 2, but that permanence (or lack thereof) played prominent roles in their findings.

Yeah, you know what, you're right. Did a bit more googling around and there's tons of stuff on both. Sorry!
