Designing successful genetic-rescue approaches for threatened species

该项目旨在确定如何通过引入基因健康的个体来“基因拯救”受威胁的近亲繁殖的本地物种种群。这一点很重要，因为澳大利亚是全球保护和受威胁物种的热点地区，因此可以用来抵消灭绝风险的工具将有利于处于危险中的整个生态系统。我们将集中在南澳的两个近亲繁殖的考拉种群，以（1）测量和绘制遗传多样性的模式，（2）绘制密度图和跟踪个体以测量人口统计学，（3）开发先进的空间模型，结合联合收割机种群人口统计学和遗传过程来预测遗传拯救的有效性，以及（4）来源和饲养健康个体来测试我们的预测。

This project aims to determine how threatened populations of inbred native species can be 'genetically rescued' by introducing genetically healthy individuals. This is significant because Australia is a global hotspot of extinctions and threatened species, so tools that can be used to offset extinction risk will benefit entire ecosystems at risk. We will focus on two inbred populations of koalas in South Australia to (1) measure and map patterns of genetic diversity, (2) map densities and track individuals to measure demography, (3) develop advanced spatial models that combine population demography and genetic processes to predict the effectiveness of genetic rescue, and (4) source and rear healthy individuals to test our predictions.
