Who "pays" the extinction debt, and why? 🦎 🏝️ 🇬🇷 Thrilled to share a new paper out now in Ecology and Evolution (open access). This work from my MSc asks how sea-level rise since the last ice age has shaped reptile extinctions on Greek islands. Read the paper here: doi.org/10.1002/ece3... 🧵(1/6)

Who Is Paying the Extinction Debt? Phylogenetic and Functional Structuring on Greek Islands Is Shaped by Sea‐Level Rise Since the Last Glacial Maximum
Since the Last Glacial Maximum, sea-level rise has isolated, fragmented, and shrunk islands, supersaturating squamate communities and triggering ongoing community relaxation. Integrating a paleo-coas...

🐕🧬 Contributed to a new paper out in @consletters.bsky.social! Using a palaeogenomic baseline, we found domestic dog introgression is limited in free-living dingoes, and associated with human population centers and lethal control practices. 1/2

🚨 You have only one more hour left to check out my poster at #TIBS2026! (Or zoom in on this picture at your leisure) 🚨 Had a blast talking to people about dingo paleobiogeography, and how my PhD aims to answer some pervasive questions about the natural history of this iconic canid. 🐕 🌏
