近几十年来，南极半岛地区的融雪显著增加，导致在更广阔的地区有更多的液态水可用。因此，如果我们要更好地了解地球最冷大陆上的陆地碳循环，就需要考虑南极湿雪中生物活动的变化。因此，本文探讨了微生物群落和化学和物理环境的湿雪栖息地的利文斯顿岛的海洋南极之间的关系。在这样做的过程中，我们揭示了细菌多样性和自养生物量在短时间内（
Snowmelt in the Antarctic Peninsula region has increased significantly in recent decades, leading to greater liquid water availability across a more expansive area. As a consequence, changes in the biological activity within wet Antarctic snow require consideration if we are to better understand terrestrial carbon cycling on Earth's coldest continent. This paper therefore examines the relationship between microbial communities and the chemical and physical environment of wet snow habitats on Livingston Island of the maritime Antarctic. In so doing, we reveal a strong reduction in bacterial diversity and autotrophic biomass within a short (
