>Dr Zach Huang did a couple of years ago.  

Yes, he shared his results with his study of cohort groups to Georgia and another
to California at EAS this past summer. 

Among the values he monitored were hypopharyngeal gland size/shape difference between
those colonies not trucked and those that were.  His hypothesis for a difference
was that nurse bees may be challenged to access pollen stores during transit.

In a separate study he recorded cluster temperatures which he found to be cooler
for trucked colonies.

I have not seen published data on either of these studies.
