Koala refuge is becoming a genetic dead end - Earth.com
A prominent koala refuge in Australia is showing signs of becoming a genetic dead end, threatening the long-term survival of its resident population. Isolated from other wild populations, the koalas here have limited opportunities for genetic diversity, which can lead to inbreeding and increased vulnerability to diseases and environmental changes. Researchers warn that without intervention, the population could face declining health and reduced reproduction rates, making conservation efforts less effective. Experts suggest introducing new koalas from different regions to restore genetic variation and strengthen the population’s resilience. The situation highlights broader challenges in wildlife conservation, where isolated refuges may unintentionally compromise species’ genetic health despite providing safe habitats. This case underscores the importance of balancing protection with strategies that maintain natural genetic diversity to ensure species survival.
