Pollinators such as wild #bees, #butterflies, and #hoverflies are in trouble worldwide. A major new study, published in Science, shows that the oft-quoted figure of 10% semi-natural habitat in farmland landscapes is far too little to safeguard pollinators

🚨 Just out in Nature Communications from my current work with fantastic collaborators @rececochange.bsky.social !

We show that moth communities are experiencing an overall “warming,” with a clear latitudinal pattern: extinction in the north and colonisation in the south.

While everyone’s attention is being zapped away by all the Chaos of Trump, this study was published today, on catastrophic losses in butterfly species abundance across the US.

“Between 2000 and 2020, total butterfly abundance fell by 22% across the 554 recorded species.” 😔

Unsurprisingly I am very much in agreement with this article. I've put a lot of effort in recently to prevent the undermining of field-based teaching, including pointing out the invisible subsidy that field-based teaching (& research) provide other teaching & research
