摘要

The length of gametophytes in the moss Sanionia uncinata and concentrations of the elements Cd, Co, Cr, Cu, Fe, Mn, Na, Ni, Pb, V and Zn in this moss and in the parent rock material were measured in West Spitsbergen (Svalbard). Samples were collected at different distances from the seashore from pure colonies in a wet moss tundra, a moderately wet moss and herb tundra, and a dry rock and terrestrial tundra. Not any statistical relation (PCCA) between concentration of elements in mosses and type of tundra habitat could be found. The principal component and classification analysis (PCCA) ordination revealed that S. uncinata from sites the most close, the most remote and on an intermediary distance from the seashore differentiated by the value of factor 1, which relates negatively to concentrations of Cd, Co, Cr, Cu, Fe, Pb and V. S. uncinata from sites situated the most close to and the most distant from the seashore was differentiated by the value of factor 2, which was negatively related to concentrations of Na, Ni and Mn in this moss. The established model points that Na, Mn, Cu, Ni and Zn were accumulated by S. uncinata mostly from sea spray.
