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?...

"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 ?

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.

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.

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.
