Seaweed-based systems on rocky reefs in south east Australia support high levels of biodiversity, endemism and economic activity (fisheries). We will provide important insight into how climate change is likely to affect the key habitat-forming seaweeds in this system, and a first assessment of how other marine species will respond to any shift in abundance of the habitat-forming seaweeds. These predictions are critical if human adaptation to effects of climate change are to be proactive and not reactive. We will also test a basic assumption of most bio-climate envelope models that are the basis of many current predictions of the effect of climate change on species distributions. The project will provide the basis for training of two PhD students.

澳大利亚东南部岩礁上的海藻系统支持高水平的生物多样性、地方性和经济活动（渔业）。我们将提供有关气候变化可能如何影响该系统中关键栖息地形成海藻的重要见解，并首次评估其他海洋物种将如何应对栖息地形成海藻丰度的任何变化。如果人类要主动而非被动地适应气候变化的影响，这些预测至关重要。我们还将测试大多数生物气候包络模型的基本假设，这些模型是当前许多气候变化对物种分布影响的预测的基础。该项目将为培养两名博士生提供基础。
