This project aims to develop integrated approaches for understanding sexual selection at the level of the gamete. It will use a new and highly versatile model system - the blue mussel - to seek insights into how multivariate selection targets ejaculates, the dynamic nature of selection, and the putative role that chemical communication between eggs and sperm plays in mediating these processes. A range of interdisciplinary approaches will be used to uncover these patterns, and the mechanisms underlying them. By focusing on a species exhibiting the ancestral reproductive strategy of broadcast spawning, the work will contribute to an understanding of major evolutionary transitions in reproductive biology.

该项目旨在开发综合方法，以了解配子水平的性选择。它将使用一个新的和高度通用的模型系统-蓝色贻贝-寻求洞察如何多变量选择目标射精，选择的动态性质，以及假定的作用，卵子和精子之间的化学通讯在介导这些过程中发挥。一系列跨学科的方法将被用来揭示这些模式，以及它们背后的机制。通过集中在一个物种表现出祖先的广播产卵生殖策略，这项工作将有助于生殖生物学的主要进化转变的理解。
