Why
Researchers at the University of Sydney and Texas A&M mapped the koala's population history over roughly the past 100,000 years and concluded that climate shifts caused the species' first major collapse.
The Frontline Impact
How this affects you
This finding changes how conservationists understand risks to koalas, emphasizing the need for better genetic tracking to make more informed conservation decisions and manage pressures from habitat destruction, disease, and fire.
