Research Topic: Impacts of climate change in northern ecosystems: carbon and nitrogen cycling northern soils and streams
Description of Research
I’m interested in the effects of climate change on nutrient cycling in northern ecosystems in both boreal and arctic regions. Northern ecosystems are experiencing relatively rapid changes in climate and are important to the global carbon cycle due to the large amounts of carbon stored within the soils. Primarily, I’m focusing on differences in soil carbon and nitrogen storage across ecosystems in Alaska, and predicting how this might change in the future, especially with permafrost thaw. I’m also looking at how changing seasonality due to climate change may affect nutrient cycling in arctic streams.
