BioEnv-seminarium: ”Warming and watering the Arctic: divergent impacts on the methane cycle in dry and wet tundra ecosystems”

Kort abstract

Increases in both air temperature and precipitation in the Arctic are two consequences of climate change; they alter ecosystem functions including vegetation composition, soil temperature, as well as soil moisture, ultimately influencing the carbon cycle. These changes alter the soil-atmosphere exchange of carbon dioxide, as well as the production and consumption of methane. To understand how an increase in air temperature and precipitation might alter the soil biogeochemistry and the ecosystem fluxes of carbon in dry and wet Arctic ecosystems we conducted an increased temperature and precipitation experiment.
