Museum samples reveal rapid evolution by wild honey bees exposed to a novel parasite

Please place treatment free research here. There's a lot of research spread around the Internet that is related to treatment free beekeeping. This forum is an effort to try and consolidate some of this, especially new research as it becomes available.

Museum samples reveal rapid evolution by wild honey bees exposed to a novel parasite

Postby msscha » Sat Aug 22, 2015 10:16 pm

Understanding genetic changes caused by novel pathogens and parasites can reveal mechanisms of adaptation and genetic robustness. Using whole-genome sequencing of museum and modern specimens, we describe the genomic changes in a wild population of honey bees in North America following the introduction of the ectoparasitic mite, Varroa destructor. Even though colony density in the study population is the same today as in the past, a major loss of haplotypic diversity occurred, indicative of a drastic mitochondrial bottleneck, caused by massive colony mortality. In contrast, nuclear genetic diversity did not change, though hundreds of genes show signs of selection. The genetic diversity within each bee colony, particularly as a consequence of polyandry by queens, may enable preservation of genetic diversity even during population bottlenecks. 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.

There we go, more data to back up a bottom up, local queen rearing, treatment free approach.
