1/ The world's songbirds sing in just 8 basic sounds. And where a bird lives decides which ones it uses. My first PhD paper is out now in @science.org (www.science.org/doi/10.1126/science.aee6239) Here is what we found:

This is interesting — a recent study of mode share (the % share of transportation trips by car, transit, walking, biking etc) relative to city size and income levels in almost 800 cities in 61 countries. Interesting results. HT @davidzipper.bsky.social www.sciencedirect.com/science/arti...

Carnivores highly active during the day were the first to go extinct after human arrival and settlement globally. Their complex life histories made them most vulnerable to habitat alteration and very salient hunting targets. nsojournals.onlinelibrary.wiley.com/doi/epdf/10....

Unsolicited listicle: My list of the most criminally underused/underappreciated phylogenetic comparative methods. Note, I am not involved in ANY of these methods; but I see them as things people are often asking of comparative data but have been surprised at how infrequently they have been cited.

Extinct Pleistocene carnivores were diurnal and highly active - fresh off the press 🐯 Only BMR and diurnality are robust predictors of extinction and this also stands for extant species 🦨🐅🦝 With @johnalroy.bsky.social we use an exhaustive sample and account for phylogenetic and trait uncertainty.

1/ A longtime Wired editor just wrote a mush-brained essay about how he totally missed the political rot of Silicon Valley (& still doesn't get it). But in the late 1990s, a Wired journalist warned of a toxic ideology bubbling up from tech. Paulina Borsook has largely been erased. Let's change that

Despite broad uptake, metascience and the Open Science reform movement have garnered ample criticism. Such criticism is also known as critical metascience. We will reflect on central critiques by bringing together key voices from a variety of disciplines, asking what needs to change, how and why?
