L'abeille mellifère, domestique, représente une seule espèce que nous sélectionnons selon nos besoins de production, de miel essentiellement. Comme les poules.
La biodiversité des abeilles sauvages, de la superfamille des Apoidea, est bien +vaste, 950 espèces en 🇫🇷. Ce sont elles qui sont en danger.

Honey bees nearly double their foraging distance by shifting and consolidating their preferred sites to remaining, isolated habitat patches within the larger land use changes. (A) Aerial imagery in 2022 of the study area in Blacksburg, VA, USA. Grey polygons represent all the lands converted in 2020-2021. Orange represents small patches of undisturbed microhabitat left within the developments. Black circle denotes the location of the hives. (B) Honey bees nearly double their communicated foraging distance in 2022 (sample size n=502) compared to 2018-2019 (sample size n=382) (mean±c.i, two-tailed likelihood ratio test used for analysis). Here each datapoint is a decoded waggle dance. (C) Honey bee foraging, as determined by dance decoding before (2018-2019, blue) and after (2022, red) the land use change, demonstrated that the bees shifted recruitment to the more distant, remaining orange patches within the grey, especially in the northern corner of the new housing development.
Robert Ostrom, @schuemaa.bsky.social and co show concrete consequences of changing land, as honey bees need to travel almost twice as far during foraging flights after construction. doi.org/10.1242/bio....

Ha salido el informe climático europeo de 2024:
- Es el continente que más se está calentando
- Las inundaciones provocaron 335 muertos
- Segundo año con mayor días con fuerte estrés térmico
Europa tiene que liderar la transición ecológica. Nos va la vida en ello.

Honeybees interfere with wild bees in apple pollination in China. Wild bees contribute much higher pollination efficiency than honeybees. Introducing honeybee colonies increased competition with wild bees leading to reduced pollination overall. besjournals.onlinelibrary.wiley.com/doi/abs/10.1...

1/8 Different types of social learning in ants
Tandem running is a form of learning in these insects, whereby an ant follows a guide who takes it to a place of interest. The two run close together, learning from one another. It seems that they do not all learn in the same way
Our new paper, based on data from 1,705 studies, shows that pesticides are toxic to organisms they are not intended to harm, including fungi, microbes, plants, insects, & vertebrates such as ourselves. Questions the wisdom of applying over 3 million tonnes of them every year...

A bee with black head and thorax, and red abdomen, sitting on a bluish white flower
My first male Osmia cornuta for 2025. This is one of the bees that has shrunk the most in size over the past few decades. 40 years ago it weighed on average 67 mg, now it has shrunk down to 54 mg, or a ~20%. Fore more details on Cazorla'a shrinking bees see our study here
