Did you know? 🐝 Pollinators support 5-8% of global crop production. Researchers observed that managed honeybees can’t compensate for wild pollinator losses nor keep pace with the growth in pollinator-dependent crops. Read more in The Guardian: https://ow.ly/o3IH50ZAq5p

Did you know Europe is running out of taxonomists - the experts who identify pollinator species? 🐝 The Pollinator Academy is an open-source platform from 25 European institutes, offering free courses, ID tools & field guides for all experience levels. 📖 👉 Check them out: pollinatoracademy.eu

Thank you WPC. "Sheila Colla was widely admired. She was far more than a brilliant scientist and conservation leader. She was a fierce advocate for environmental and social justice and was incredibly skilled and determined at bridging the gap between science, community, and politics."

Ce que la famille Trump trame en Albanie peut tout à fait être compris comme une forme de colonialisme privé.

Sometimes you've gotta go metallic to mimic your model! This common tropical hover #fly at the top is a convincing mimic of the local orchid #bees in the genus #Euglossa (bottom). #FlySchool2026 #Syrphidae: #Ornidia obesa Soltis Center, Costa Rica

Bordeaux, France, has now recorded more days above 40°C in 2026 alone than during the entire 105-year period from 1920 (when observations began) to 2025. This is deeply shocking.

Les conséquences s’annoncent «catastrophiques», a affirmé la ministre française de la Transition écologique.

Que dit la science sur l'acétamipride et le flupyradifurone, les deux pesticides qui pourraient être réintroduits après l'adoption de la loi d'urgence agricole ? De nombreux chercheurs pointent les risques de ces insecticides pour les pollinisateurs, mais aussi pour d'autres animaux ainsi que...

I ate a lot of mangoes this summer in India, and somehow kept wondering how this fruit comes to be. My first science write-up dives deep into it, and is featured in today’s edition of The Hindu. www.thehindu.com/sci-tech/ene...

It's a red kangaroo. Always amazed by people's weird decisions. And just how does one smuggle a roo into Canada? If someone is willing to fork out 6 grands, the incentive is there. www.cbc.ca/news/canada/...

Des chercheurs de 13 universités dénoncent le projet de loi C-30 qui permettra au gouvernement Carney d’invalider la science. Il donnera le pouvoir au Conseil des ministres de réautoriser des pesticides risqués interdits par Santé Canada. ici.radio-canada.ca/nouvelle/225...

Comme nous l'expliquons dans une lettre au sujet du projet de loi C-30 "Il n’existe aucun fondement scientifique ou autre motif raisonnable pour justifier qu’une décision réglementaire soit infirmée par le Conseil des ministres après que Santé Canada a mené des examens approfondis."

Very cool version of this monthly global average surface temperature anomaly chart showing both El Niño and La Niña years

quick, look at an Andrena vs Colletes comparison before it becomes irrelevant, until like July. Colletes are big spring guys and only show up rarely later in the year.
