This project will investigate the impact of environmental change on larval energetics of molluscs on the southeast (SE) coast of Australia. The SE coast of Australia is a climate hotspot characterised by rising ocean temperatures, fluctuations in salinity and we expect in the near future ocean acidification (OA). Mollusc larvae show extreme sensitivity to OA, but the impacts of other stressors remains unknown. It is predicted that OA will reduce the capacity of larvae to cope with temperature and salinity, particularly when food supply is low and in populations which have had no previous exposure to OA. Understanding the response of mollusc larvae to environmental change will support ecologically and economically significant mollusc populations over this century.

本项目将研究环境变化对澳大利亚东南海岸软体动物幼虫能量学的影响。澳大利亚东南海岸是一个气候热点，其特征是海洋温度上升，盐度波动，我们预计在不久的将来海洋酸化（OA）。软体动物幼虫对OA异常敏感，但其他应激源的影响尚不清楚。据预测，OA将降低幼虫应对温度和盐度的能力，特别是在食物供应不足和以前没有接触过OA的种群中。了解软体动物幼虫对环境变化的反应将在本世纪支持具有生态和经济意义的软体动物种群。
