As the oceans simultaneously warm and acidify, prospects for marine biota are of concern. This project aims to determine the potential for phenotypic adjustment and evolutionary adaptation. To discern the roles of phenotype and genotype in marine invertebrate stress tolerance this project endeavours to use selection experiments, long-term rearing and quantitative genetics . A focus on vulnerable calcification systems could determine genetic mechanisms underlying impaired growth. Investigation of species from the east Australia latitudinal thermal gradient, a global change hot spot could generate insights into biological responses and adaptive potential in a changing ocean and on time scales relevant to resource managers to understand the challenges faced by marine biota.

随着海洋同时变暖和酸化，海洋生物群的前景令人担忧。该项目旨在确定表型调整和进化适应的潜力。本计画将利用选择实验、长期培育及数量遗传学的方法，来探讨海洋无脊椎动物逆境耐受的表现型与基因型。对脆弱的钙化系统的关注可以确定生长受损的遗传机制。对东澳大利亚纬度热梯度这一全球变化热点的物种进行调查，可以深入了解在不断变化的海洋中的生物反应和适应潜力，并了解与资源管理人员有关的时间尺度，以了解海洋生物群面临的挑战。
