Managing habitat for flowering plants may mitigate climate effects on bee health

Warm, wet weather conditions and changing climate negatively influence the nectar intake and nutritional health of honey bees, but maintaining large tracts of grassy natural habitat with flowering plants around apiaries may help to mitigate the detrimental effects of climate, according to a new study by an international team of researchers.

The Secret Chemistry that Makes Honey a Scientific Wonder

It should come as no surprise that bees know a lot about honey. They aren’t only honey producers — they are also consumers and pretty sophisticated ones at that. Offer a sick bee different varieties of honey, for example, and it will choose the one that best fights off its infection.
