This project aims to measure the genetic health of key populations of threatened Australian mammals. With the highest rate of extinction in the world and over 30% of surviving species under immediate threat, Australian mammals require urgent focus to secure their future. This project focuses on island populations, which are increasingly used as sources to rewild mainland Australia. Using cutting-edge genomic tools, this project plans to determine the extent and nature of genetic variation, including harmful mutations, on islands and in declining mainland populations. The anticipated outcome is to understand how genetic factors contribute to extinction, to improve conservation strategies for threatened species.

该项目旨在测量受威胁的澳大利亚哺乳动物关键种群的遗传健康。澳大利亚哺乳动物的灭绝率是世界上最高的，超过30%的幸存物种受到直接威胁，因此需要紧急关注以确保它们的未来。该项目的重点是岛屿种群，这些种群越来越多地被用作恢复澳大利亚大陆的资源。该项目计划利用最先进的基因组工具，确定岛屿上和大陆人口减少中遗传变异的程度和性质，包括有害突变。预期的结果是了解遗传因素如何导致灭绝，以改善受威胁物种的保护策略。
