Initial Validation of a Replicated Field-scale Denitrifying Bioreactor Facility in a Boreal Environment

Received: 29 December 2020;  Published: 15 April 2021;  doi: 10.21926/aeer.2102005


Denitrifying bioreactor technology, where a solid carbon source (wood chips) acts as a reactive medium to intercept agricultural tile drainage water, has been successfully used to convert nitrate (NO3-) to di-nitrogen (N2) gas. Four full-size field-scale (80ft long x 10 ft. wide x 4 ft. deep), repli [...]

Linking Population and Forest Dynamics over the Conterminous US for the 1990s and 2000s

Received: 24 September 2020;  Published: 09 March 2021;  doi: 10.21926/aeer.2101003


Few studies have investigated deforestation and population connections in the U.S. at large spatial extents or small scales. We examined forest cover changes over two decades, 1990-2000 and 2000-2010, in the continental U.S. at the county scale. Forest dynamics were estimated using the National Land [...]
