It is important to remember that the hives out in the woods are not wild but cast-off swarms of domesticated honey bees, and that the mating behavior of honey bees will fold in genetics from many hives in a region ( drone congregation areas represent feral and backyard and commercial hives in a rather vast area ).
The genetic research seems to point to the opposite happening - that because of pressures on honey bees from pesticides or pests ( and thereby viral pressure carried by various pests ) the feral and commercial populations track quite closely.
https://www.nature.com/articles/ncomms8991 https://www.nature.com/articles/ncomms8991 - there's a lot here specifically relevant to this discussion but especially note the emergence of African Honey Bee genotype in wild populations. This paper is from 2015 analyzing the biodiversity response to the arrival of V. destructor ( varroa mites ) and Africanized bees were introduced in the early 1990s as well.
The take-away is that until you have a 3 mile separation of water, assume that populations of bees in a land area are more related than not and face similar pressures in a given climate, whether feral or managed. Honey Bees especially ( but of course every living thing ) should be managed with an ecosystem mindset.
- timr 1y agoA few things: a) African honey bees aren't domesticated populations, challenging your overall point. b) A 3 mile separation is not substantial (though I grant you that if most of the bees in any given cluster are introduced, then it might lead to more homogeneity). c) even within "wild" populations of whatever, you see local clusters of genetic similarity. It's been a while since I took population genetics, but IIRC this kind of local equilibrium was well-covered. Also, I haven't read the paper, but the abstract sure sounds like what I'm describing -- a sudden population bottleneck leads to rapid evolutionary adaptation in wild populations: "These findings suggest that genetically diverse honey bee populations can recover from introduced diseases by evolving rapid tolerance, while maintaining much of the standing genetic variation."
