This recent paper by colleagues Szymon Czyżewski and @jcsvenning.bsky.social from @econovoau.bsky.social calls for nothing less than a paradigm shift in the way we should view European forests🌲🌳🌱 w 🐗🫎🐮 as some of the main (missing) players.

Hopefully it will resonate!

So what actually happened when the dinosaurs died?🦕

Using simple ecological rules*, we explore how the interplay between ecosystem engineering, seed size and light environment can explain temporal patterns of animal and seed sizes from the fossil record🌳🐘🐀🌱
