Declines in terrestrial ecosystem health as a result of a drying climate have been observed in some areas of East Antarctica. This project aims to determine if such changes are widespread. Since mosses, the dominant plants of Antarctica, preserve a record of past climate down their shoots they can be used as surrogates to study how both ecosystems and climate are changing at remote polar sites. Outcomes will include improved climate data for Antarctica, enabling more robust analysis of regional climate change, and development of ultrahigh-resolution techniques capable of non-destructively monitoring Antarctic ecosystem health. This research will advance ecosystem science and inform best practice in management of Antarctic biodiversity.

在南极洲东部的一些地区，由于气候干燥，陆地生态系统的健康状况有所下降。该项目旨在确定这种变化是否普遍存在。由于南极洲的主要植物苔藓保存了过去气候的记录，它们可以作为替代物来研究偏远极地地区的生态系统和气候如何变化。其成果将包括改进南极洲的气候数据，从而能够对区域气候变化进行更有力的分析，并开发能够非破坏性监测南极洲生态系统健康的超高分辨率技术。这项研究将促进生态系统科学，并为南极生物多样性管理的最佳做法提供信息。
