Summary

Story summary

Pumas have returned to Patagonia, Argentina, threatening Magellanic penguins that had little land-predator pressure.
A study published in Proceedings of the Royal Society B shows pumas are adapting to prey on these seabirds.
Ecologist Mitchell Serota, the study's lead author, investigates how this shift affects puma movement patterns and interactions.
The resurgence reshapes Patagonia's ecological dynamics, altering predator–prey relationships for penguins that previously thrived without significant land predators.
