Temperature and soil nutrients are key factors limiting plant growth in the Swedish subarctic tundra, and rising temperatures associated with global climate change are thus predicted to have major impacts on tundra ecosystem functioning. Elevational gradients provide excellent opportunities to study how changes in temperature and associated climatic factors that shift with elevation influence community and ecosystem properties, and the processes that govern nutrient availability for plants. In collaboration with researchers here and at the Climate Impacts Research Centre (CIRC), Department of Ecology and Environmental Science, Umeå University, I study the effect of elevation on soil nutrient availability, plant and soil microbial communities, and plant-soil linkages in subarctic tundra. For this research, we use an elevational gradient situated near the town of Abisko in the northermost part of Sweden.
