This project aims to assemble comprehensive long term Australian plankton records spanning 50 to 1000 years, by applying ancient DNA technology to dated sediment depth cores. Long-term data for Australian coastal and estuarine waters are sparse, so cannot be used for management of fisheries, tourism or urban development. Long-term records are essential to understand how disruptive algal and jellyfish blooms, introduced species and increased human use of coastal resources affect dynamic plankton ecosystems. This project’s findings are expected to explore cyclical patterns, define range expansions and understand and manage how dynamic coastal ecosystems respond to multistressor anthropogenic change. Findings will improve understanding of how dynamic marine environments retain their biodiversity values and critical ecological functions.

该项目旨在通过将古代DNA技术应用于沉积物深度测年岩芯，收集跨越50到1000年的澳大利亚长期浮游生物记录。澳大利亚沿海和河口水域的长期数据很少，因此不能用于渔业、旅游业或城市发展的管理。长期记录对于了解破坏性的藻类和水母繁殖、引入的物种以及人类对沿海资源利用的增加如何影响动态浮游生物生态系统至关重要。预计该项目的发现将探索周期性模式，确定范围扩大，并了解和管理动态的沿海生态系统如何对多重应激源的人为变化做出反应。这些发现将提高对充满活力的海洋环境如何保持其生物多样性价值和关键生态功能的理解。
