When a plant or animal population is in serious decline, it can enter what's called a genetic bottleneck. Fewer individuals means less genetic diversity, which in turn makes it harder for the species ...

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 ...

“Just keep looking up,” our guide instructs us as we start walking through a small tree-dotted park near the ferry terminal on Raymond Island. “Koalas are everywhere.” It sounds too good to be true, ...

Andrew Weeks is an Adjunct Research Fellow at the University of Melbourne and a Director of Cesar Australia, a small research based company that works in the fields of sustainable agriculture and ...

A rapid koala rebound in southeastern Australia is also boosting their genetic variation, showing one way out of an extinction death spiral. After nearly disappearing from the region over a century ...
