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.

该项目旨在利用家鼠，这是一种具有重要经济意义的澳大利亚害虫，也是一个非常易于处理的系统，用于测试进化理论并产生实际结果。控制种群性别比例是增强受威胁物种生存能力或消灭害虫的有力工具。然而，尽管进行了大量科学努力来检验性别比例理论，但驱动性别分配的神秘机制仍然未知，阻碍了这些领域的进展。该项目将确定性别比例调整的机制，并确定个人层面的反应如何影响岛屿人口结构和增长。它将通过协助澳大利亚消除入侵老鼠种群的努力来带来好处。
