There appears to be some confusion here on terminology. A "small hive"
generally means a small *colony* in a single box, not a large colony in
multiple boxes with the broodnest confined to a single brood chamber. This
thread originally had nothing to do with single brood chamber management.
I agree with Bill T that the effect upon longevity of very small
*colonies* appears
to be due to a larger proportion of the workers extending their time as
nurses before transitioning to mid-age and foraging duties. Note in
Rueppell's Fig 5 that when they finally started foraging, those
extended-nursing foragers didn't live very long.
Note also that those very small colonies focused upon pollen collection to
feed those nurses, rather than upon nectar collection.
