Historical reconstruction unveils the risk of mass mortality and ecosystem collapse during pancontinental megadrought

There is growing concern that an increase in the frequency and severity of drought under climate change could drive major changes in Australian ecosystems. This collection provides data that supports recent research reported in Godfree et al. 2019 (PNAS, in press). The database contains information on the impact of the Federation Drought Period (1891-1903) on Australian biota extracted from newspaper articles and other historical literature.\nLineage: The database was constructed by extracting information on the impacts of drought on Australian biota during the period 1891-1903. The main information source consisted of newspaper articles and a small number of supplementary historical documents. Full details are provided in the main text of Godfree et al. (2019) and the SI Appendix referenced therein.

学界与公众日益担忧，气候变化背景下干旱发生频率与严重程度的提升，可能会引发澳大利亚生态系统的重大改变。本数据集为Godfree等人2019年发表于《美国国家科学院院刊》(Proceedings of the National Academy of Sciences，简称PNAS，待刊)的最新研究提供数据支撑。该数据库收录了从报纸文章及其他历史文献中提取的、关于联邦干旱期（1891年—1903年）对澳大利亚生物区系造成影响的相关信息。
数据集构建说明：本数据库通过提取1891年—1903年期间干旱对澳大利亚生物区系的影响相关信息构建而成，主要信息来源为报纸文章与少量补充历史文献。完整细节请参见Godfree等人2019年研究的正文及其中引用的补充信息附录(SI Appendix)。
