What effects does urban beekeeping have on wild bee populations? This is what a new study that looked at the negative effects of urban honeybee rearing on wild bee populations and was published in Peerj intends to solve. For the study, the researchers analyzed data from 2013 and 2020 that was gathered from locales on the island of Montreal, and what they discovered was rather astounding.“We found that the sites with the largest increase in honeybee populations across sites and years also had the fewest wild bee species,” said Dr. Gail MacInnis, who is a research scientist at the GPRC-CRI National Bee Research Center but conducted the study as a postdoctoral researcher at Concordia University, and lead author of the study.
