Could Imported Sperm Help Save America’s Bees?

It might be time to call in some sexual backup for male American bees. Scientists have started impregnating domestic honeybees with foreign sperm in the hopes that enlarging the gene pool will give our bees a fighting chance.

These days, the bees need all the help they can get. Colonies across the globe are disappearing and dying off, partly due to the increased use of neonicotinoid pesticides and partly from a parasite called the varroa mite. The invasive mite first landed on American shores in 1987, and it's been spreading and sickening and devouring our bees ever since.

Part of the problem, researchers say, is that the American bee gene pool has gone stagnant. We stopped importing live honeybees in 1922, which means that all the bees we've got are inbred and, therefore, all alike. They lack the genetic diversity that allows species to adapt to changing conditions or new threats. So when the mites come, they all get hit.

Many apiarists now rely on anti-mite pesticides to keep their charges safe. While these treatments may help keep the mites away, they aren't great for the bees, either—and the mites have begun to develop a resistance. But beekeepers feel like their hands are tied.

"I lost 40 percent of my colonies to varroa last fall," Matthew Shakespear of Olson's Honeybees told NPR. "I'm not taking any more chances. We've already done five treatments, compared with the two treatments we applied this time last year."

But there might be another way. Experts at the University of Washington have started to—how can we put this delicately?—manually encourage drones (male bees) in Europe and Asia to give up their sperm. All it takes is a little belly rub, and the drone, er, donates 1 microliter of fluid, or one-tenth of the amount needed to inseminate a queen bee.

"They're really accommodating," bee breeder and researcher Susan Cobey told NPR. 

It's hardly a painless procedure, but researcher Brandon Hopkins told Mental Floss it's no worse than sex in the wild. "In natural mating he uses pressure from muscles and hemolymph to evert [his genitals], (inflating it and forcing it to pop out)," Hopkins wrote in an email. "In the lab we apply pressure to the head and thorax to create similar pressure to cause the eversion. In both cases (naturally and artificially) the male dies from the process of mating."

So far, the scientists' attempts to crossbreed foreign and domestic bees have been successful. Within their test colonies, genetic diversity is up.

"This doesn't mean they are superior in performance to the other bees," Hopkins told NPR. "It means we have a better chance of finding rare and unique traits." Traits, Hopkins says, like genetic resistance to the varroa mites—a quality shared by donor bees in Italy, Slovenia, Germany, Kazakhstan, and the Republic of Georgia.

Other beekeepers are opting for a more hands-off approach, introducing imported queens to their domestic hives. Shakespear bought his from Cobey, who reared them from bees she collected in Slovenia.

"Maybe these new genetics can deal with the varroa mites naturally," Shakespear said, "rather than having to rely on chemicals. It's time to start widening our gene pool."

Pretty in Pink: Drone Captures Birds-Eye View of Massive Flamingo Flock in Kazakhstan

Flamingos sport some of the most eye-catching plumage in the animal kingdom. Their diet of beta-carotene-rich plankton and crustaceans produces a distinctive pink hue that's hard to miss. One flamingo is striking on its own, but the birds are even more impressive as a crowd, as demonstrated by the footage below.

As Fox 13 Tampa Bay reports, Azamat Sarsenbayev used a drone to capture this video of flamingos congregating on Lake Karakol near Aktau, Kazakhstan. A flamingo flock (also called a flamboyance) can contain up to several hundred birds. Flamingos do a lot together, including mating displays. From above, everyday life for a flamingo makes for a breathtaking, candy-colored spectacle.

This footage was taken during the species' migration south. By the end of their journey, the birds will likely be settled in the Khazar nature reserve or even farther south in Iran. After checking out the video, read up on these fascinating facts about flamingos.
