High nitrate variability on an Alaskan permafrost hillslope dominated by alder shrubs
Abstract 3 - 3 -N (nitrogen from nitrate) concentration of 4.27 ± 8.02 mg L- 1 0.23 ± 0.83 mg L- 1 p < 0.05). Temporal variation in NO3 -N within and downslope of alder shrubland co-occurred with precipitation events where NO3 - that accumulated in the soil was likely flushed downslope during rainfall. These findings have important implications for nutrient availability and mobility in N-limited permafrost systems that are experiencing shrub expansion in response to a warming Arctic.
