This project aims to bridge the gap between physiology and ecology in kelp forest species by developing mechanistic models to predict change and, in an unprecedented step, test them in long-term experiments at naturally acidified sites to understand the consequences of ocean acidification (OA) and warming for kelp forests. Ecosystem change is a frequent outcome of decadal modifications of the physical and chemical environment. Whilst these changes often involve degradation from productive states, we have a poor understanding of the mechanisms which drive change. Key stressors in marine systems, OA and warming are predicted to drive loss of kelp forests but we still don't understand the reality of these predictions.

该项目旨在通过开发预测变化的机制模型，弥合海带森林物种生理学和生态学之间的差距，并以前所未有的步骤，在自然酸化地点进行长期实验，以了解海洋酸化和海带森林变暖的后果。生态系统变化是物理和化学环境十年变化的一个常见结果。虽然这些变化往往涉及生产状态的退化，但我们对推动变化的机制了解甚少。海洋系统中的关键压力因素，OA和变暖预计会导致海带森林的消失，但我们仍然不了解这些预测的现实。
