(a) Carbon-to-nitrogen (CN) ratio, (b) ammonium content, (c) nitrate content, and (d) δ15N of soils (0–5 cm depth). Bars denote standard deviation (n = 3). A normal distribution assumption was accepted for CN ratio and ammonium content, and a log-normal distribution assumption was accepted for nitrate content and δ15N. BL, study site in Blomstrandhalvøya; ST, study site in Stuphallet; n.s., not significant. The grey bar shows the δ15N range for lipid or liver tissue of three seabird species (black-legged kittiwake, northern fulmar, and Atlantic puffin).
