(Phys.org, Flinders University) A new study has identified two species of Australian bee that have adapted their vision for night-time conditions. Both species have developed enlarged compound and simple eyes which allow more light to be gathered when compared to their daytime kin. “Before this study, the only way to show that a bee had adapted to low-light was by using difficult-to-obtain behavioral observations, but we have found that you should be able to figure this out by using high-quality images of a specific bee.”

(Florida Blueberry Growers Association) Blueberry growers know that to get good yields, you need bees. So researchers looked at the three main pollinators of blueberries in Florida: honey bees, managed bumble bees and southeastern blueberry bees (Habropoda laboriosa). They found that the southeastern blueberry bee had the greatest effect on both percent fruit set and yield.
(Wired) The growing interest in hobbyist beekeeping has some ecologists worried. The European honey bee, as its name might suggest, is not native to North America. While honey bees are a managed pollinator species, about 4,000 species of native bees also call the US home, including its urban areas. One group of researchers observed dozens of wild species across several Chicago neighborhoods, while another nature organization recorded more than 200 species in New York City. Now, some ecologists are concerned that with so much human help, the newcomers might outcompete their wild cousins, causing an ecological ripple effect that would threaten both the bees and the plants that depend on them.
(BBC) Buglife Cymru said it discovered a “strong population” of small scabious mining bees at a local nature reserve. It said it marked the first time the species had been found in the city of Newport or the surrounding area.
(East Oregonian) While a lack of regional data doesn’t allow for definitive conclusions on how increased temperatures will impact regional bee populations, preliminary data alludes to the dangers they face. They suggest that as temperatures rise in the region, the variance and quantity of bumble bee species may decline.
(Yale E360) As suitable sites become scarce, commercial beekeepers are increasingly moving their hives to U.S. public lands. But scientists warn that the millions of introduced honey bees pose a risk to native species, outcompeting them for pollen and altering fragile plant communities.
