Research into climate change and the development of human societies has received considerable attention[1,2].By comparing paleoclimate records with major historical events in human society,previous studies have found that the development of human societies might be closely linked to climate change[3,4].In particular,large-scale hydrological changes caused by climate change have directly affected agricultural productivity and further caused population migration and social conflict.

The sediments of crater lakes were one of the ideal archives for high-resolution paleoenvironmental reconstruction. This paper collected sedimentary records of 21 crater lakes in monsoonal China and systematically discussed the geographical distribution and formation ages of these crater lakes. Sediment provenance of crater lakes and its influencing factors were analyzed， and paleoenvironmental sequences and human activities records on different timescales reconstructed by crater lake sediments in monsoonal China were reviewed. The following points are highlighted: (1) Crater lakes in monsoonal China have been shown to preserve continuous long-time sediments that can exceed even 400 kyr， although the chronology of some sediments in southern China is debated and there were currently fewer long time records from northeastern China; (2) The sediment provenance of crater lakes in northern China (e.g. aeolian inputs) was different from that in southern China (e.g. the volcanic-lake rim)， due to the different location and deposition conditions of crater lakes; (3) Crater lake sediments have been used to reconstruct the history of climate changes on different timescales， but reconstruction studies of glacial-interglacial and decadal-annual scale records and studies of spatial comparisons of records on different timescales still need to be strengthened; (4) The anthropogenic signals， which include cultivation， logging， and industrial activity， are well documented in crater lake sediments from different areas and can therefore provide key evidence for the study of the Anthropocene. Crater lake sediments are vital paleoclimate archives for the reconstruction of high-resolution climate changes and for the understanding of the impact of anthropogenic activities. However， there are still questions that need to be solved， and a more comprehensive study of crater lake sediments is expected in the future.

金黄色葡萄球菌(Staphylococcus aureus)是引起食源性疾病爆发的重要致病菌之一,传统的金黄色葡萄球菌检测方法包括培养法、生化鉴定法、核酸分析法、免疫分析法等,其可靠性高,但操作相对繁琐、费时,且灵敏度较低。生物传感器是一种由生物学、光学、化学等多学科交叉渗透发展形成的新型微量分析技术,具有灵敏度高、分析速度快等特点,被广泛应用于食源性致病菌的检测。本文对比了金黄色葡萄球菌的传统检测方法,重点讨论了近年来基于适配体、噬菌体、纳米材料的电化学或光学等金黄色葡萄球菌生物传感器的检测新方法,并对其未来发展趋势进行了展望。
