This project aims to understand how sexual conflict drives the evolution of “manipulative” nuptial gifts in male arthropods and how females respond to ingesting these gifts. Nuptial food gifts comprise materials (other than sperm) that are offered by males to females to consume at mating, and are an integral feature of the mating systems of a wide variety of arthropods. The project will study the decorated cricket, a species where males produce a nuptial food gift that contains a cocktail of chemicals known to influence female reproduction when eaten. The project is expected to strengthen Australia’s international standing in evolutionary research and help train the next generation of evolutionary biologists.

这个项目的目的是了解性冲突如何驱动雄性节肢动物的“操纵性”婚姻礼物的进化，以及雌性如何回应这些礼物。婚姻食物礼物包括由雄性提供给雌性在交配时消耗的材料（精子除外），并且是各种节肢动物交配系统的一个组成部分。该项目将研究装饰蟋蟀，这是一种雄性产生的婚礼食物礼物，其中含有一种已知会影响雌性生殖的化学物质。该项目预计将加强澳大利亚在进化研究方面的国际地位，并帮助培养下一代进化生物学家。
