WebNov 26, 2015 · AsianScientist (Nov. 26, 2015) – The koala genome has been studied across the species range for the first time, revealing revealed that koalas ( Phascolarctos cinereus) are genetically diverse. The study, published in Conservation Genetics, indicates that declining populations are the result of human-related activity rather than mating with kin.
WebGenetic diversity is important for the long-term persistence of a species as it provides populations with the capacity to cope with pressures such as disease or climate change.

Koala retrovirus (KoRV) subtype A (KoRV-A) is currently in transition from exogenous virus to endogenous viral element, providing an ideal system to elucidate retroviral-host coevolution.
