Things I want to learn more about over the next year

I have a handful of hypotheses that I want to explore over the next twelve months.  Along with a few friends, hopefully we'll gain some more insight into these curious bee related questions.

1) When honeybees build a nest inside a tree void, does the tree absorb the moisture created by condensation due to the heat the bees create and redistribute that moisture through the rest of the tree?

2) When honeybees build a nest in a tree void, does the presence of the bees promote and encourage beneficial aspects for the tree?  For example, does the application of propolis inside the void promote healing of any damage the tree may have sustained due to the void having been created?

3) Primary swarms are often the biggest to issue from the old nest and take the "old" queen with it.  Most of the bees in the primary swarm are also "old" bees.

My question...is a "prime Swarm" really a "colonizing" or "building"  swarm whose primary function is to build new nests out in the world, regardless of the survival of the bees in the swarm over the following season?

Do the bees in a Primary swarm "know" they are not so much building a nest for them, but for a next swarm? 

Do the scout bees in a Primary swarm look for a large void that does not already contain wax comb in it or only maybe a little?

4) Secondary and even tertiary swarms that leave a colony usually have a virgin queen and mix of old and younger bees.

Do the bees in a secondary swarm look primarily for a void that already has comb built in it? 

Are they more of an "occupying" swarm instead of a "building" swarm due to their typically lower numbers?

Do the bees in a secondary swarm "know" they are more of an "occupying" swarm rather than a "colonizing" swarm?

5) Ultimately, as bees take on specialized tasks within a colony among the three castes, do swarms also have a specialized purpose as a "super-organism" as well?

I am working on ways to test these out and I already have a few other local people who are interested in helping me investigate some of these questions.  With bees, there is always more to learn.
