Freshwater ecosystems are experiencing an unprecedented combination of changes caused by climate warming. One of the greatest physical changes at mid- and high-latitudes is the shortening of seasonal ice cover and the accompanied changes in snow accumulation and watershed vegetation. Shifts in under-ice ecological processes have year-round repercussions on primary productivity, food availability for higher organisms and greenhouse gas emissions. As Canada Research Chair in Boreal and Polar Aquatic Ecology, Dr. Milla Rautio will focus on seasonally ice-covered ecosystems with the overall aim to improve our understanding of physical and biogeochemical conditions during winter and their effects on aquatic microbial and planktonic life.

淡水生态系统正在经历气候变暖引起的前所未有的变化组合。中高纬度地区最大的物理变化之一是季节性冰盖的缩短以及随之而来的积雪和流域植被的变化。冰下生态过程的变化对初级生产力、高等生物的食物供应和温室气体排放产生全年影响。作为加拿大北方和极地水生生态学研究主席，Milla Rautio博士将专注于季节性冰雪覆盖的生态系统，其总体目标是提高我们对冬季物理和生物地球化学条件及其对水生微生物和水生生物的影响的理解。
