The study found that climate shifts, specifically drying conditions during the last ice age, caused the koala population's first major collapse.
The Frontline Impact
How this affects you
This research redefines the historical understanding of koala decline and provides new insights for conservation efforts, including assessing remaining resilience and informing decisions against modern threats like habitat destruction and disease.
