Briefings

A 2026 study published in Ecology analyzed 12 years of degus data from central Chile, showing the species survived nearly a decade of megadrought until the 2019 extreme drought caused local disappearance. The research highlights how extreme drought overwhelms wildlife resilience, with specific focus on endemic rodent populations in arid regions.

Key points

• Degus in central Chile survived nearly a decade of megadrought before disappearing locally after the 2019 extreme drought.
• The study analyzed 12 years of population records to track resilience against prolonged environmental stress.

Context

This research provides critical insights into how extreme drought events can overwhelm wildlife resilience, specifically in endemic rodent populations of arid regions like central Chile.

Limitations

Data covers only 12 years of records; the specific city or region of central Chile is not explicitly named in the source evidence.
