Manipulating population sex ratio to eradicate invasive mouse populations

该项目旨在使用家鼠，这是一种澳大利亚重要的经济害虫，也是一个高度易处理的系统，用于测试进化理论并产生实际结果。控制种群性别比是提高受威胁物种生存能力或消灭害虫的有力工具。然而，尽管对性别比理论进行了大量的科学测试，但驱动性别分配的神秘机制仍未确定，阻碍了这些领域的进展。该项目将确定进行性别比调整的机制，并确定个人层面的反应如何影响岛屿人口的结构和增长。它将通过帮助澳大利亚根除入侵老鼠种群的努力而带来好处。

This project aims to use house mice, an Australian pest of economic importance which is also a highly tractable system for testing evolutionary theory and generating practical outcomes. Manipulating population sex ratio is a powerful tool for either enhancing the viability of threatened species or decimating pests. However, despite much scientific effort testing sex ratio theory, the cryptic mechanisms driving sex allocation remain unidentified, hindering progress in these fields. The project will identify the mechanisms by which sex ratio adjustments are made and establish how individual-level responses influence insular population structure and growth. It will provide benefits by assisting Australia's efforts in eradicating invasive mouse populations.
