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 ...

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 ...

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

A new study reveals that habitat fragmentation can lead to sudden "tipping points" where a species' genetic health unexpectedly collapses after appearing stable for long periods. By merging network ...

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 ...

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 ...
