Found in my Interweb stumblings tonight.
Research from 2010 on the effect of migratory
beekeeping on certain structures and hormone levels in the honeybee. Audio/video quality isn't the best, but seems like the study was well designed. The TL;DR is that the only structure that showed a statistically significant effect was the hypopharyngeal gland, which was "significantly smaller" in migrated
bees. The researchers seemed to think that the damage wasn't reversible, and that it could have effects on future generations of bees (via suboptimal queen rearing).

Same researchers published a paper correllating long distance transport stress to Nosema:

Seems to give some more scientific backing to Paul/Jacqueline's Colony Collapse
video on bee stress.
