📄Out now 📄: 90-year trends in Switzerland show declines in butterfly and saproxylic beetle richness around the mid-20th century, linked to agricultural mechanisation. Some groups have recovered in recent decades, especially warm-adapted species. Specialised and cold-adapted species remained low.🦋🪲

A combined figure with figure panels from the publication. One panel (panel a) showing the trends in Switzerland-wide relative richness of butterflies and saproxylic beetles, with clear declines of butterflies until the 1980s and declines followed by increases for the saproxylic beetles. The other panel (panel b) shows trends of relative species richness for the two insect groups divided by different traits. In the upper part of the figure, groups are built based on the habitat specialisation of the species and it is evident in both groups, that habitat specialists declined strongest. In the lower part of the figure, groups are built based on temperature niche of the species and it is evident that while warm-adapted species have declined strongest until the 1980s, they have clearly reversed their trends and are now increasing strongly.A photo of Lycaena virgaureae, a species with specialised food resources that has mostly disappeared from the Swiss lowlands in the last 90 yearsA photo of Aromia moschata, a longhorn beetle that has become rare in the mid 20th century, but which has increased in recent decades

Please enjoy this ridiculously cute butterfly, which was about the size of my pinkie fingernail. It's in the butterfly family called metalmarks (Riodinidae). Males, like these, have reduced front legs and perch using only the rear 4 (females can use all 6). Sarota acantus; Costa Rica 🐙🌿 #insects

A macro photo, front three-quarter view, of a little butterfly perched on a green leaf. The butterfly has pale green eyes with black speckles, legs covered in thick yellow fuzzy hair, and orange wings sprinkled with metallic light blue patches. It is very cute.A macro photo, side view, of a little butterfly perched on a green leaf.

Our global study on the state of trust in scientists is now out in Nature Human Behaviour! 🥳 With a team of 241 researchers, we surveyed 71,922 people in 68 countries, providing the largest dataset on trust in scientists post-pandemic 👇🧵https://www.nature.com/articles/s41562-024-02090-5

More than 90% of fossil fuel emissions occurred since my parents were born. Over 80% since I was born. Over 30% since my children were born. And well over 50% since the world agreed at the Rio Earth Summit to prevent dangerous climate change. And I thought: „At last!“
