摘要：

Samples of two species of widely distributed mosses (Sanionia uncinata and Hylocomium splendens) were collected in the Ariekammen-Fugleberget catchment area (Hornsund, Spitsbergen) within and outside little auk Alle alle (L.) colonies. The concentrations of Cd, Pb, Ni, Zn, Cu, Mn, Fe, N, P, and S in the moss samples were found to be 1.5-2 times higher within than outside the colonies. Significant differences were found for Cd, Pb, Zn, Cu, and Fe, but not for Ni, Mn, N, P, and S. Sanionia uncinata accumulates up to 8-mu-g g-1 d. wt Cd, 14-Pb, 8-Ni, 47-Zn, 9-Cu, 90-Mn, and 1920-mu-g g-1 d. wt Fe, while Hylocomium splendens accumulates up to 4-mu-g g-1 d. wt Cd, 12-Pb, 3-Ni, 31-Zn, 5-Cu, 60-Mn, and 840-mu-g g-1 d. wt Fe. The colonies of seabirds contribute greatly to the supply of elements in the tundra ecosystems of southern Spitsbergen. The effect seems, however, to be limited to rather small areas.
