This project aims to understand the mechanisms behind climate-mediated declines in kelp. Ocean warming causes the collapse of valuable temperate kelp forests globally and on both sides of Australia, but it is unknown if this is because of direct physiological effects from temperature or the indirect effects of changes in species interactions. This project will compare the direct effects of marine heatwaves to the indirect effects of range-shifting tropical herbivores and pathogens for the kelp forests of the Great Southern Reef, one of Australia’s largest coastal ecosystems. This project will generate knowledge underpinning adaptation strategies for these critical ecosystems, and could enhance the capacity to respond to degradation of these natural assets.

该项目旨在了解海带中气候介导的下降背后的机制。海洋变暖会导致全球和澳大利亚两侧的宝贵温度海带森林的崩溃，但是尚不清楚这是否是由于温度的直接物理作用或物种相互作用变化的间接影响。该项目将将海洋热浪的直接影响与范围转变的热带草食动物和病原体的间接影响对澳大利亚最大的沿海生态系统之一的海带森林的海带森林的间接影响。该项目将为这些关键生态系统产生基础的适应策略的知识，并可以增强对这些自然资产退化的反应能力。
