With increasing elevation, seed mass is expected to be either larger for its advantage during seedling establishment in stressful high-elevation environments (“stress-tolerance” mechanism) or smaller due to energy constraints. Based on the combination of inter- and intra-specific analyses on 4,023 populations of 320 Tibetan plant species, we found an overall positive within species but negative among...
In this study, we built up a database of 633 species (48 families, 205 genera) from an alpine meadow on the eastern Qinghai-Tibet plateau. Our objective was to assess the effects of phylogenetic and life-history (life form, perenniality, seed size, dispersal strategy and period) background on the community-wide germination strategies. We found that the seeds of shrubs, perennials, and well-dispersed...
