The differences of seed rain between typical and swamp meadows on the eastern Tibetan Plateau

Abstract

Abstract: Seed rain, as a potential community, plays important roles in maintenance of biodiversity. In both typical and swamped meadow of eastern Tibetan Plateau, we studied the relationship between seed rain and vegetation on their species composition and seasonal dynamics. The results showed that, 1) There were no significant differences in species richness, Shannon index and individual density for vegetations between typical and swamp meadows, but NMDS (nonmetric multidimensional scaling)revealed that there was a clear separation of species composition between them; 2) Seed rain density in typical meadow was significantly higher than that of swamp meadow; 3) The seasonal dynamics of seed rain density both in typical and meadow exhibited bimodal patterns; 4) The similarity of seed rain between typical and swamp meadows were higher than that of vegetations, which was confirmed by the NMDS ordination analysis.
