The Role of Soil Nutrients in Arctic Greening
Are soil nutrients providing a limit to recent Arctic greening? We hypothesise that nitrogen, in certain Arctic contexts, may become progressively more limited over decades to centuries. To test this hypothesis, we are using shrub wood anatomy and dendroecology methods to extract information about nutrient availability over long time-scales. This will be combined with mechanistic modelling approaches to test our hypotheses. Current field sites are based on the Yamal Peninsula, Arctic Russia.
