The workflow illustrates a step-by-step process for conducting causal analyses. Arrows indicate the typical flow of an analysis. Two possible pathways are shown: causal discovery approaches (blue), which aim to identify the existence of causal relationships when pre-existing knowledge is low, and causal inference approaches (yellow), which aim to quantify the direction and magnitude of causal effects when pre-existing knowledge is high. The gray feedback loop on the right highlights the iterative refinement of causal analyses based on assessments of the plausibility of causal assumptions.

So, y'all have heard me going on about #causalinference in #ecology a lot. Now our big synthetic guide "Best practices for moving from correlation to causation in ecological research" is out! Led by Hannah Correia & Paul Ferraro, it's a great walk-through for all! 🌍🧪 www.nature.com/articles/s41...

Why the Shape of Continents Mattered Across 500 Million Years of Climate Change New fossil evidence shows how geography influenced who survived Earth’s climate shifts

Extinction isn’t random.

Range size matters. Temperature tolerance matters. Climate change matters.

But there’s another piece we’ve long suspected: geography.

For 500 million years, the shape of continents helped shape survival.

New behavioral #paleontology paper out today about tyrannosaur predation! The authors (Wyenberg-Henzler & Scannella) contend that the find is "consistent with a bite inflicted during an attempt to control the struggling Edmontosaurus or deliver a killing blow followed by carcass consumption". Nice!

Antarctica isn’t one big tipping point.

New research maps 18 separate ice basins, each with its own threshold. Some in West Antarctica may tip at just ~1–2C warming (i.e close to today’s levels).

Porpoises 'buzz' less when boats and ships are nearby.

Hydrostatic pressure induces strong leakage of dissolved organic matter from “marine snow” particles Particles sinking into the deep ocean come under pressure and leak dissolved organic matter, which affects marine carbon cycling.

Not all marine snow—oceanic dandruff made of fecal flakes, dead phytoplankton, and more—makes it to the seafloor.

Researchers in #ScienceAdvances describe the deep-sea squeeze that causes carbon from these particles to leak into seawater before reaching the ocean’s bottom. https://scim.ag/3Zh1kCU

Smart people have already written about the many problems of generative AI better than I could, but I’ll tell you this about the thing I know: writing is about writing. It’s an action. A verb. It’s what we do. I write, you write, they write. Skip that and you’re not a writer.

Increasing bottom marine heatwaves pose a critical risk to Mediterranean benthic species Konsta et al. assess the exposure of Mediterranean benthic species to projected marine heatwaves occurring at the seafloor. Their analysis reveals that current and future habitats of these species will experience long-lasting, intensifying bottom marine heatwaves. This reflects a basin-wide pattern where, by the end of the century, extreme bottom marine heatwaves are expected year-round. Their findings underscore the necessity for targeted conservation strategies to mitigate heatwave impacts on Mediterranean benthic species.
