The preservation of Australia's biodiversity depends on understanding its origins and the mechanisms that prevent its disappearance. Interacting genes, such as those coding for the machinery of the cell, evolve together and can prevent the fusion of species during hybridisation. This occurs because the cellular machinery evolves independently in different species, leading to incompatible parts that fail in hybrids. This project will investigate novel genetic mechanisms that lead to reduced hybrid survival and reproduction, and therefore to the preservation of species. Australian students will receive advanced training at the frontier where ecology, genetics, and molecular biology intersect.

保护澳大利亚的生物多样性取决于了解其起源和防止其消失的机制。相互作用的基因，如那些编码细胞机制的基因，一起进化，可以防止物种在杂交过程中融合。这是因为细胞机制在不同物种中独立进化，导致不相容的部分在杂交中失败。该项目将研究导致杂交后代存活和繁殖减少的新的遗传机制，从而保护物种。澳大利亚学生将在生态学，遗传学和分子生物学交叉的前沿接受高级培训。
