Fig. 4: Effects of beaver dam on floodplain nitrate fluxes.
From: Beaver dams overshadow climate extremes in controlling riparian hydrology and water quality
a Total nitrate exported from flow paths between 5 and 30 m in length between April 7 and October 31, 2018, with and without the beaver dam. b Nitrate exported from these flow paths, expressed as a fraction of total nitrate imported over the same time period, with and without the beaver dam (blue and green lines, respectively). Flow paths shaded in gray are those that export nitrate when the dam is not present. Flow paths shaded in magenta are those that export nitrate only in the presence of the beaver dam. Flow paths shaded in beige do not export nitrate under either condition.
