Announcement of the event on 11.11.2025, 13:30-15:00 in the EU- Parliament "How can the CAP drive sustainable farming practices: Voices from farmers and science, and an evaluation of the CAP proposal"

Next week in the EU-Parliament (11.11.2025, 13:30-15), we will discuss the future of sustainable farming in Europe and the alignment or non-alignment of the CAP with sustainability criteria, based on @agtransect.bsky.social and #CAP4GI.

I cannot believe our work is finally out there and in @journal-evo.bsky.social ! This was an enormous group effort!

We provide an updated estimate of the number of buzz pollinated angiosperm species, genera, and families, look at consequences for diversification, number of transitions, and more!

The new European Butterfly Red List is published today, with worrying findings. Over 1/4 (28%) of Europe’s 442 species are threatened with extinction or are close to being so. The situation is far worse for our 148 endemic species, 40% are now threatened or nearly so www.bc-europe.eu/webpage.php?...

Les papillons et les abeilles sauvages toujours plus menacés en Europe Plusieurs dizaines de nouvelles espèces risquent la disparition, selon l’Union internationale pour la conservation de la nature, qui vient de mettre à jour sa liste rouge.

"L’état de conservation des abeilles sauvages, des papillons et autres pollinisateurs européens est désastreux, a réagi Jessika Roswall, la commissaire européenne à l’environnement".

Sans doute l'article le plus important du WE.
Quand va-t-on vraiment réagir ?

King penguins are pretty impressive divers, logging descents of over 300m in the summer, but now researchers @iphc-strasbourg.bsky.social have discovered that the penguins dive even deeper in winter, remaining submerged for up to 10mins & descending up to 424m

Out now in @globalchangebio.bsky.social: "Pesticide Risk Assessment in a Changing World"

Our climate is changing, and biodiversity is declining. In this context, accurate pesticide risk assessments to insect pollinators and crop auxiliaries -pivots of food security in a changing world- is crucial.

Thanks! Any feedback/insight is more than welcome!

Pesticide Risk Assessment in a Changing World The assessment of the risks posed by pesticides to biodiversity and ecosystems often relies on domesticated model species and measures of acute lethality, leading to an incomplete understanding of th...

Namely, we highlight how to integrate 1) the non-linear interactions between multiple environmental stressors (e.g. heat stress, malnutrition, pesticide exposure); 2) the ecological consequences of pesticide transformation products, which can have lethal and sublethal effects on many organisms.

In this opinion piece, we synthetize the ecological and evolutionary complexities of pesticide exposure in the context of global change and propose a holistic approach for environmental risk assessments.
