What to know about Elephant declines could trigger wider ecosystem losses in African savannas, 15-year test shows

A study published in the journal Science describes how the removal of African elephants from savanna ecosystems leads to a significant decline in dung beetle populations and associated ecological functions. The research, conducted over 15 years at Kenya's Mpala Research Center, suggests that elephants act as a keystone species whose presence supports biodiversity and provides economic value to cattle industries.

What happened

Elephant declines could trigger wider ecosystem losses in African savannas, 15-year test shows Sadie Harley Scientific Editor Andrew Zinin Lead Editor For decades, ecologists have theorized that the extinction of one important species could set off a chain…

Why it matters

Now, new research offers some of the clearest real-world evidence that this idea of coextinction is not just theoretical.

Common ground

The study, led by Princeton University doctoral student Finote Gijsman and co-authored by University of Florida Professor Todd Palmer Ph.D., found that African elephants function as a keystone species for dung beetles across Kenya's savannas.
