Global warming is predicted to form 'sick seas' and cause widespread stunted growth of taxa and ecosystem-wide dwarfism. Exactly how this works requires substantiation of both short-term empirical and experimental research as well as evidence from the deep-time fossil record. Using the high-resolution marine fossil record from the Permian-Triassic mass extinction ~252 million years ago, the most severe in the history of animals, this project will investigate how body size of marine species and communities evolved in response to the mass extinction and rapid global warming. It is expected that the project findings will help better understand the links between global warming, anoxia, hypercapnia, euxinia, ocean acidification, and species adaptation and evolution.

据预测，全球变暖将形成“病海”，并导致生物分类群和生态系统范围内的侏儒症的广泛发育不良。这究竟是如何工作的，需要短期经验和实验研究的证实，以及来自深时间化石记录的证据。本项目将利用2.52亿年前二叠纪-三叠纪大规模灭绝的高分辨率海洋化石记录，研究海洋物种和群落的体型如何应对大规模灭绝和快速全球变暖。预计该项目的研究结果将有助于更好地了解全球变暖，缺氧，高碳酸血症，真石脂，海洋酸化和物种适应和进化之间的联系。
