A new chapter begins! Starting this September, I’ll be working on bird macroevolution at @ebdonana.bsky.social . Excited for this new adventure and the amazing research ahead 🐦🐤🪶

🚨 I'm looking for #Postdoc opportunities starting this September! 🧑‍🔬🔍
I'm a highly motivated researcher with experience in R, network analysis, and multivariate statistics. My focus is on the evolution of ecosystems and biodiversity over deep time.

9/ This paper is the result of over 7 years of work—a true collective effort. Huge thanks to all my co-authors for making this possible! @ohsanisidro.bsky.social @singerstone.bsky.social @amniotalab.bsky.social et al.

5/ This event also led to an acceleration in functional diversity increase. For the first time, all major herbivore orders—Proboscidea, Artiodactyla, and Perissodactyla—coexisted across continents, expanding ecological roles and reshaping ecosystems at a global scale.

4/ 🌀First tipping point (~21 Ma):
Triggered by tectonics—Africa and Eurasia connected via the Gomphotherium land bridge.
This unleashed a wave of faunal migrations and global functional reorganization (Proboscideans out of Africa for the first time).

3/ Across time, we found long phases of functional stability, where ecosystems retained their structure despite species turnover.
But we also found two major, irreversible tipping points in global herbivore faunas—moments of drastic ecological reassembly.

2/ We used network analysis and trait data (like body size & tooth shape) from 3,000+ species to reconstruct the functional structure of global ungulate ecosystems over the past 60 million years.
Rather than focusing on taxonomy, we asked: What ecological roles they played?

1/ Large herbivores (like ancient elephants, rhinos, deer) aren’t just big plant-eaters—they’re ecosystem engineers. They shape landscapes, disperse seeds, and influence soil and fire dynamics.
But how did they evolve as climates and continents shifted?
