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.

Radar data find no decline in insect numbers—but there’s a catch Study of continental U.S. sees stable population of bugs, but it may be missing important pieces of the puzzle

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

Species loss in key habitats accelerates regional food web disruption - Communications Biology Simulating extinctions across regional food webs reveals that losing species from one habitat— especially wetlands—can cascade to others, accelerating multi-habitat food web collapse, highlighting the...

🚨 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...

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. The butterfly has pale green eyes with black speckles, legs covered in thick yellow fuzzy hair, and orange wings sprinkled with metallic light blue bands and patches. It is very cute.

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

Four graphs showing the relationship between abundance on the y axis and (i) day of the year (bimodal), (ii) temperature (positive), (iii) elevation (positive) and (iv) proportion of forests (positive). Sketches of five moths on the left side.

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.

Das Ende des Wissenschaftsmagazins Das SRF-Wissenschaftsmagazin soll auf Ende Jahr eingestellt werden. Wir fragen nach: Warum dieser Entscheid? Und wie sind die Reaktionen aus der Wissenschaft? Zudem: Wie uns künstliche Intelligenz umg...

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...

Graphical representation of the hypothesized causal flow analysed in the study. in hypothesis 1, functional community features (represented as green boxes) mediate the effect of land-use intensity on acknowledged stability drivers within trophic levels. in hypothesis 2, functional traits of the lower trophic level mediate the effects of land-use intensity by influencing stability drivers both directly and indirectly through changes in the functional composition/diversity of higher trophic levels

New paper about how effects of #land-use intensity on community stability are mediated by #functional traits in managed #grasslands and #forest. Based on lots of field data on both #plants and #arthropods 🌱🌳🦋🐞🕷️📈

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 🌲🌏 🧪

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.

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!“
