Africa-Press – Angola. <\/strong><\/span>Researchers in Australia say freezing koala sperm could help protect the endangered marsupials from extinction.<\/b><\/p>\n

Scientists at the University of Newcastle in New South Wales have suggested setting up a biolab of collected sperm.<\/p>\n

This could then be used as part of a breeding programme to future-proof the species and improve its genetic diversity, they say.<\/p>\n

Bushfires in recent years have killed tens of thousands of koalas.<\/p>\n

Cuddly koala’s genes could halt sex disease<\/p>\n

Koalas face extinction in New South Wales by 2050<\/p>\n

Koala listed as endangered species in much of eastern Australia<\/p>\n

Conservation scientist Dr Ryan Witt said the proposals were a cost-effective way to prevent inbreeding, and therefore help preserve the genetic diversity of koalas beyond small colonies of captive animals:<\/p>\n

“Currently… we have no insurance policy against natural disasters like the 2019-2020 bushfires that threaten to wipe out large numbers of animals at the one time,” he said.<\/p>\n

“If the koala population dies in these kind of fire events, there is no way to bring them back or preserve their genetics.”<\/p>\n

Live koala young have been born following assisted reproduction using fresh or chilled sperm, the researchers say.<\/p>\n

“By using frozen sperm, we can reintroduce genetic variation into wild koala populations without having to relocate koalas,” said Dr Lachlan Howell, also of the University of Newcastle.<\/p>\n

“We’ve identified 16 wildlife hospitals and zoos across Australia that could act as nodes to collect koala sperm,” he added.<\/p>\n
