Scientists have discovered a potential path out of devastating genetic bottlenecks that could help these Australian animals, ...

Koalas were officially declared endangered Friday in eastern Australia. This comes as the marsupials continue to fall prey to chlamydia and lose their habitats to land clearing and climate change.

A landmark finding that suggests koala genetic diversity not the only deciding factor in successful regrowth of populations.

Some koalas may recover their genes after major population crashes. Growing koala populations may rebuild genetic strength over time.

Koalas spend most of their time in trees — but are in deadly danger when they descend to the ground, new research shows. The marsupials are an endangered species in Australia and their populations are ...

The amazing ability of dogs to detect and track down specific scents could have profound effects on Australia's koala population. Perhaps surprisingly, koalas are particularly prone to chlamydia.

One was a koala. The other was a husky. Both were arguably out of place on a warm August night in subtropical Brisbane, the capital of Queensland in Australia’s northeast. Home security video captured ...
