极地冰川底部微生物多样性及其对气候变化响应的研究概况与前景
PROGRESS OF DIVERSITY OF ECOSYSTEMS BENEATH POLAR GLACIERS AND THEIR RESPONSES TO CLIMATE CHANGE
摘要
Abstract
Investigation of the characteristics and adaptive strategies of life beneath ice sheets and glaciers is at the forefront of polar research. Many studies have reported that liquid water and organic matter coexist in subglacial regions, providing a suitable microbial habitat. Furthermore, the presence of microbes beneath polar glaciers can modulate geochemical weathering processes, although this is likely to be affected by cli-mate-forced environmental changes. Considering the diversity of ecosystems beneath polar glaciers and their responses to climate change, this study elucidated the microbial characteristics, their possible origins, the mechanisms of the biogeochemical processes occurring beneath polar glaciers, and the influences of subgla-cial microbial life on the C and N cycles. The objective was to provide a reference resource for future sub-glacial research.关键词
