Abstract

ABSTRACT The distribution data of 18 categories (including 446 species) of bryophytes in 66 islands of the Zhoushan Archipelago, China were complied. By using the matrix temperature and the NODF metrics under six null models, we evaluated their nestedness levels and explored possible mechanisms to form nested distribution with partial Spearman correlation and the random placement model. The main results were as follows: 1) all the 18 categories of bryophytes exhibited a high degree of nestedness; 2) nestedness level was higher for mosses than liverworts, higher for acrocarpous mosses than pleurocarpous mosses, and also varied among families; 3) the nested distribution of bryophytes in the archipelago was not due to passive sampling, but mainly due to nested habitats and selective-extinction; 4) spore size might be a factor linked to selective-colonization accounting for nestedness of some bryophyte categories; and 5) nestedness level was higher for families with a high proportion of generalists than those with a high proportion of specialists, the conservation of the latter should cover more islands (patches).

舟山群岛苔藓植物巢性的定量分析与解释

摘要整理了舟山群岛66个岛屿18类446种苔藓植物的分布资料。利用6种零模型下的矩阵温度和NODF指标，评估了它们的嵌套程度，并探讨了部分Spearman相关和随机放置模型形成嵌套分布的可能机制。结果表明:1)18类苔藓植物均表现出高度的筑巢性;2)藓类的筑巢水平高于苔类，顶荚藓类的筑巢水平高于胸荚藓类，且科间存在差异;③群岛苔藓植物的巢状分布不是被动取样的结果，而是巢状生境和选择性灭绝的结果;4)孢子大小可能是苔藓植物选择定殖的一个因素;⑤通才比例高的家庭巢性水平高于专才比例高的家庭，专才的保护应覆盖更多的岛(斑块)。
