Mate choice near and far: Genetic compatibility, sexual selection, and speciation in Australian grass finches

点击翻译按钮获取中文摘要

The pressure on individuals to choose a genetically compatible partner has the capacity to drive the evolution of mating systems and the process of speciation, and is therefore a major engine of biodiversity. Reproductive failure resulting from incompatibility between individuals is more likely when individuals from fragmented and genetically structured populations mate with one another. This work will give new insight into biological processes that drive biodiversity and effect the management of threatened populations and endangered species. The proposed research will raise the international profile of Australian science and biodiversity and improve our ability to manage our natural biological resources.
