Nested pattern of mosses and their conservation strategies at a large scale: based on data from nature reserves and forest parks of the eastern China

On a large spatial scale, investigation and clarification of geographical distribution pattern of moss diversity in China is of significance for overall arrangement in relation to diversity reserves. In this paper, the floristic data of 1 534 moss species from 80 reserves and national forest parks in the eastern China were collected. Based on these data, the nested level of mosses and their main categories among 80 geographical units, and the SLOSS (single large or several small) strategies were analyzed. The results indicated that significant nested distribution patterns were found in mosses (as a whole), pleurocarpous mosses, acrocarpous mosses, Buxbaumiidae-Polytrichidae mosses, Spagnaceae, Pottiaceae, Brachytheciaceae, Orthotrichaceae, Dicranaceae and Bryaceae by using either matrix temperaute or NODF metrics, with a significance value at P
