🚨 Hot off the press! We show that species loss from key habitats (like wetlands) accelerates secondary extinction in regional multi-habitat food webs. Also, we show the importance of common species to regional food web robustness. doi.org/10.1038/s420...

Species loss in key habitats accelerates regional food web disruption - Communications Biology
Simulating extinctions across regional food webs reveals that losing species from one habitat— especially wetlands—can cascade to others, accelerating multi-habitat food web collapse, highlighting the...

Nice reporting from @meganewald.bsky.social on point if use #eDNA detections of West African Manatees

Excited for what the future holds in being able to rapidly test for endangered cryptic species - particularly the rotund ones
Africa’s manatees are highly elusive. A new DNA test promises to reveal their presence
Genetic traces in water could help survey populations under growing threat

Pre-print alert! 🚨 Excited to share my second PhD chapter: species link habitats through food webs. We show that removing species from one habitat (e.g., wetlands) can cascade across the multi-habitat regional food web, reducing its robustness. 🌿🐝🐦🦌 Check it out here: doi.org/10.21203/rs....
