📄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.🦋🪲

New study on arthropod declines @natecoevo.nature.com 🪲 In two time series @jena-experiment.bsky.social & @bexplo.bsky.social we show how community (dis)assembly underpins local biomass declines. It mostly boils down to species loss, with identity losing relevance. www.nature.com/articles/s41...

„The fall of a prolific science journal exposes the billion-dollar profits of scientific publishing“ 🧪🎓 english.elpais.com/science-tech... Many of my colleagues in ecology will know the name of the journal: Science of the total environment (STOTEN)

The first study to survey insect populations on a continental scale finds no evidence of widespread decline, at least over a recent 10-year period. https://scim.ag/4pnb6hN

Interested in nocturnal #moths? ☑️ Check our new BE-Paper in @oikosjournal.bsky.social: #Land-use intensification reduced trait & phylogenetic beta #diversity - mainly in common moths. Rare #forest species responded differently. Body size ↓, wing load & darkness ↑. 🔗 doi.org/10.1002/oik.... 🌐

Thrilled to announce the publication of the trophiCH database: a multi-trophic, species-level #metaweb for #Switzerland🇨🇭 Out now in #ScientificData 📃 www.nature.com/articles/s41... Want to explore the dataset? 🔍 webapps.wsl.ch/trophiCH/ #OpenData #Ecology #FoodWebs 🌐 1/6

🚨 Hot off the press! We show that species loss from key habitats (like wetlands) accelerates secondary extinction in regional multi-habitat food webs. Also, we show the importance of common species to regional food web robustness. doi.org/10.1038/s420... #Ecology #FoodWebs #Biodiversity #Metaweb

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

Radio SRF streicht die Sendungen/Podcasts „Trend“ und das Wissenschaftsmagazin. Noch weniger Hintergrund zu Wirtschaft und Wissenschaft - doch genau das, was die Demokratie im Kampf gegen die Irrationalität der internationalen Fascho-Oligarchie braucht.

Es kam sehr überraschend: Am Donnerstag fiel der Entscheid der SRF aus Spargründen das "Wissenschaftsmagazin" zu streichen. Zusammen mit anderen Forschern (u.a. @erichfischer.bsky.social @florianaltermatt.bsky.social) habe ich meine Bedenken geäussert www.srf.ch/audio/wissen...

Insect communities in windthrows peaked at the very beginning of two study decades and then slowly declined 🪲 Salvage-logging affected species composition, thus a mosaic of logged and unlogged windthrows best promotes biodiversity 🌲🌏 🧪 🔗 https://buff.ly/40ysYwz

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

OK, here is a very rough draft of a tutorial for #Bayesian #SEM using #brms for #rstats. It needs work, polish, has a lot of questions in it, and I need to add a references section. But, I think a lot of folk will find this useful, so.... jebyrnes.github.io/bayesian_sem... (use issues for comments!)

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!“

Insect apocalypse? No! Intercropping can be a solution: besjournals.onlinelibrary.wiley.com/doi/full/10....

[new paper] You probably suspected that loss of pollinator diversity consistently reduces reproductive success for wild and cultivated plants, but here we quantify it: www.nature.com/articles/s41...
