Interesting new study highlights heathland land management (e.g. sheep grazing) as more important than honey bee competition for free-living pollinator communities. besjournals.onlinelibrary.wiley.com/doi/10.1111/... … 1/2

Heathland pollinator communities are more strongly influenced by land management than by honeybee competition
Apiaries had modest impacts on heathland plant–pollinator communities, likely buffered by the abundance of Calluna vulgaris which provides 91% of landscape nectar during hive introductions. We recomm...

'Insect-friendly' glyphosate — the most widely used herbicide globally — reduces honey bee foraging by 13% but, interestingly, not waggle dance metrics. Interesting, but unfortunately paywalled, but I'll discuss it in a future post on The Apiarist. doi.org/10.1242/jeb.... #beekeeping #notducks

Sublethal glyphosate exposure reduces honey bee foraging and alters the balance of biogenic amines in the brain
Summary: In honey bees, sublethal exposure to the herbicide glyphosate reduces foraging and induces positive correlations in the brain content of octopamine and its precursors tyramine and tyrosine.
