Beaver engineering in the Arctic tundra induces hydrologic and geomorphic changes that are favorable to methane (CH _4 ) production. Beaver-mediated methane emissions are driven by inundation of existing vegetation, conversion from lotic to lentic systems, accumulation of organic rich sediments, ele...
