Without interrupting their busy sleep schedule, Australia’s cute, if cantankerous, koalas have turned a truism of genetics on its head. In short, the proliferation of certain koala populations shows ...

Around a decade ago, koalas nearly vanished from southeastern Australia due to the fur trade. In the 1920s, as few as 500 individuals remained in the state of Victoria. Conservationists kicked off a ...

A new study reveals that habitat fragmentation can lead to sudden "tipping points" where a species' genetic health ...

Koalas suffered a massive population decline that left them with dangerously low genetic diversity. However, new genomic research suggests their rapid rebound may be helping reverse some of that ...

If you follow media coverage of koalas, you could be forgiven for feeling confused. Recent stories describe a “koala paradox”: endangered in the north of Australia, abundant in the south; genetically ...

As koalas in southern Australia have grown from a few hundred to almost half a million, the marsupials show signs of regaining lost genetic variation.

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

Koalas’ population comeback may be doing more than boosting numbers—it could also be rebuilding their lost genetic diversity.

Population genetics explores the distribution and change in frequency of alleles within and between populations, while genetic diversity underpins the capacity of species to adapt to environmental ...

Songbirds who make the arduous flight from their nesting sites in northern boreal forests to warm, southern climates in the winter may be rewarded for their journey with greater genetic diversity.
