🚨 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...
