Correlations between the Moss Floras of Japan and New Zealand(Part Two Natural History Study)

概要

論文の詳細を見る
The moss floras of Japan and New Zealand are reviewed based on the literature. The two countries have comparatively rich and unique moss floras for their land areas, which might be due to climatic diversity, locally high precipitation, complicated topography, as well as geological history. Japan and New Zealand also have in common many tectonically active hotspots with frequent volcanic activity and earthquakes. The moss floras of these two widely-separated areas have a total of over 1,500 species. A comparison of the mosses recorded from Japan and New Zealand reveals that the Japanese moss flora is richer than that of New Zealand, but that the endemism rate at the species level in New Zealand is higher than that of Japan. Although their moss floras are different in their species composition, nearly 90 species are common to both areas. Of the species with disjunctive ranges, several might be considered more or less cosmopolitan with little geographical significance. Others are extremely interesting, and require further studies and explanations.
