The practical experiment is to run Island mated Buckfast colonies side by side with your locally adapted bees in the same apiary and compare like for like.depends on the definition of weather... min or max temperature, rate of heat loss, hours of sunshine...
Which I did for a few years.
Buckfast are so superior in just about every way in my near moorland habitat that I gave up with the locals.
When I asked them about their preferred min max temperatures and hours of sunshine they said Bzzzzzz off.
If you look historically in the UK we appear to have only recently re-discovered insulation. Sort of re-inventing the wheel. The original tended "hives" were tree nests, followed by log gums (chopping the nest out of the tree) although this was never very strong in the UK..Which tended more towards straw skeps plastered and insulated with a thick layer of mud and cow dung. Woodbury in the late 1800 early 1900's introduced one of the first double walled hives where the inside gap was filled with cork chippings for insulation during the winter and removed in the spring...followed closely by the similar WBC which was lighter and cheaper to produce....but with time (possibly due to 2 world wars) many forgot to insulate the gap.
Nothing new in beekeeping. And the bees have survived despite the less than ideal conditions many colonies have (and are) kept in.
