From: Seabird-affected taluses are denitrification hotspots and potential N2O emitters in the High Arctic
Copy numbers of denitrifier genes encoding nitrite reductase (nirS cluster I, nirK cluster I, and nirK cluster II) and nitrous oxide reductase (nosZ clade I and nosZ clade II) in soils. Bars denote standard deviation (n = 3). Different letters denote a significant difference (P < 0.05) under a log-normal distribution assumption. BL, study site in Blomstrandhalvøya; ST, study site in Stuphallet; U, talus (upper part); M, talus (middle part); L, talus (lower part); C, control area not directly affected by seabirds.
