Brown Lemming Herbivory Experiment Data, Alaskan Arctic (summers 2018, 2019) Jessica Plein, Donatella Zona, Rulon Clark, Kyle Arndt, Walter Oechel, and Douglas Stow

Short summary
Tundra vegetation and the carbon balance of Arctic ecosystems can be substantially impacted by herbivory. We tested how herbivory by brown lemmings in individual enclosure plots have impacted carbon exchange of tundra ecosystems via altering carbon dioxide (CO2) and methane (CH4) fluxes. Lemmings significantly decreased net CO2 uptake while not affecting CH4 emissions. There was no significant difference in the subsequent growing season due to recovery of the vegetation.
