Understanding how plants and animals responded to past changes in climate can help us to predict what might happen in the future, yet there are key gaps in our knowledge of past processes. Genetic evidence shows that many Antarctic species have been isolated on the continent for millions of years, but during the last Ice Age, Antarctica was blanketed in glaciers. How could species have survived such extreme conditions and how did they respond to past global warming? This project will analyse genetic diversity patterns to test whether Antarctic species survived ice ages on ice-free land near volcanoes and, capitalising on the unique setting of Antarctica, will give insights into the role of volcanoes in promoting biodiversity in cold regions.

了解植物和动物对过去气候变化的反应可以帮助我们预测未来可能发生的事情，但我们对过去过程的了解存在关键差距。遗传证据显示，许多南极物种在大陆上被隔离了数百万年，但在最后一个冰河时代，南极洲被冰川覆盖。物种如何在如此极端的条件下生存下来，以及它们如何应对过去的全球变暖？该项目将分析遗传多样性模式，以测试南极物种是否在火山附近的无冰陆地上存活下来，并将利用南极洲的独特环境，深入了解火山在促进寒冷地区生物多样性方面的作用。
