图6. 千岛湖研究区物种、岛屿大小和分散贮食动物相对多度对种子扩散距离的影响。A, 岛屿大小和6个物种种子扩散距离的关系(平均值+标准差)。B, 分散贮食动物相对多度和6个物种种子扩散距离的关系。不同小写字母表示同一岛屿大小物种间差异显著(p < 0.05)。

Fig. 6. Effects of species, island size and relative abundance of scatter-hoarders on seed dispersal distances in the study area of the Thousand Island Lake region. A, Relationships between island size and seed dispersal distances for six species (mean + SD). B, Relationships between relative abundance of scatter-hoarders and seed dispersal distances for six species. Different lowercase letters indicate significant difference at the 0.05 level among different species for the same island size. Cg, Cyclobalanopsis glauca; Cs, Castanopsis sclerophylla; Lg, Lithocarpus glaber; Qa, Quercus acutissima; Qf, Quercus fabri; Qs, Quercus serrata.
