Climate change is reshaping terrestrial Arctic ecosystems. Increases in mean summer temperature and days above freezing are exacerbating permafrost thaw and altering edaphic characteristics of tundra soils. This impacts the structure and function of Arctic soil microbial, animal, and plant communities, and rates of soil nutrient cycling. Improved knowledge of climate change effects on soil ecosystems is necessary to inform predictive ecological and climate models and to understand how these changes may impact ecosystem services. This session will explore how a warming climate is driving changes in Arctic soil ecology. Contributions examining the impact of climate change on permafrost and tundra soil processes, with focus on microbial, animal, and plant community structure and function, are encouraged.
