The facts to include in the research paper would include the fact that the current genetic diversity of koalas is low as populations in Australia have genetic differences that point to a limited gene flow between populations.
How the diversity affect survival
Low genetic diversity can affect the long-term survival of Koalas as inbreeding depression may affect their resilience to environmental stressors and make them more susceptible to diseases. Also, the Koals may become less adaptable to environmental changes.
As of 2022, the Australian Koala Foundation claimed that there were between 32,000 to 58,000 koalas while the Australian government claimed that there were up to 400,000 koalas still left in the wild.
