The more #honey #bees in an #urban #environment, the fewer #wild #bees. #Pollen availability declines as well.
New paper by MacInnes et al. (2023), with research conducted in #Montreal: https://peerj.com/articles/14699/
Quote: “To support our native bees and encourage #ecologically #responsible urban #beekeeping, introductions of honey bee colonies could be accompanied by deliberate planting of #flowers known to provide abundant #pollinator resources…”
The spatial heterogeneity of urban landscapes, relatively low agrochemical use, and species-rich floral communities often support a surprising diversity of wild pollinators in cities. However, the management of Western honey bees (Apis mellifera L.) in urban areas may represent a new threat to wild bee communities. Urban beekeeping is commonly perceived as an environmentally friendly practice or a way to combat pollinator declines, when high-density beekeeping operations may actually have a negative influence on native and wild bee populations through floral resource competition and pathogen transmission. On the Island of Montréal, Canada there has been a particularly large increase in beekeeping across the city. Over the years following a large bee diversity survey ending in 2013, there was an influx of almost three thousand honey bee colonies to the city. In this study, we examined the wild bee communities and floral resources across a gradient of honey bee abundances in urban greenspaces in 2020, and compared the bee communities at the same sites before and after the large influx of honey bees. Overall, we found a negative relationship between urban beekeeping, pollen availability, and wild bee species richness. We also found that honey bee abundance had the strongest negative effect on small (inter-tegular span <2.25 mm) wild bee species richness. Small bee species may be at higher risk in areas with abundant honey bee populations as their limited foraging range may reduce their access to floral resources in times of increased competition. Further research on the influence of urban beekeeping on native and wild pollinators, coupled with evidence-based beekeeping regulations, is essential to ensure cities contain sufficient resources to support wild bee diversity alongside managed honey bees.

On #HolocaustMemorialDay we remember Borys Romanchenko (96), who survived Buchenwald, Dora & Bergen-Belsen concentration camps during WWII, but was killed on 18.3.2022 in a bomb attack on his home in Kharkiv by the Russian army
Survived Hitler, murdered by Putin
Lest we forget!🕯️

Marianne North traveled to 6 continents & 17 countries, painting exotic plants in remote & hazardous jungles… all while traveling alone in Victorian dress in the 1800s.
North depicted over 1,000 scientifically accurate pitcher plants, orchids, ferns & more. Her oil paintings introduced botanists to multiple previously unidentified species & several are named after her.
Her art has its own gallery at Kew Royal Botanical Gardens. https://artsandculture.google.com/story/marianne-north-an-unsung-pioneer-of-botanical-art-kew-royal-botanic-gardens/OQVB7c9EslEtHQ?hl=en #HistoryRemix #history #art #science
