What do the diets of ice age mammals tell us about the biodiversity crisis?

Our new research in @ScienceMagazine asks how extinction and range loss have affected land mammal food webs globally over the last 130,000 years 🧵

#ScienceResearch science.org/doi/10.1126/sc… We show how declines in land mammals have rippled across the web of life by degrading food webs

We chart what we’ve lost, what more we’ll lose if endangered species go extinct, and what potential exists for reversing losses by restoring extant mammals to their historic ranges
