Short summary
Decaying animals perturb soil biogeochemical cycles. Stable δ15N composition, which reflects the sum of all biogeochemical processes, increases during decay and persists for years. Enrichment following beaver decay persisted after at least 1 year, and was evident up to 10 cm depth and 60 cm from the decaying animals, beyond where soils were visibly impacted by decomposition. Nutrients sourced from decaying animals represent an integral and long–lived component of nitrogen cycling in soils.
