Research on the bryoflora of Dongling Mountain, Beijing, China

  • The composition and characteristics of the bryoflora of Dongling Mountain in Beijing were studied based on field surveys and specimen collection. Results showed that 150 species of bryophytes (including two varieties) belonging to 64 genera and 27 families were recorded from Dongling Mountain, of which 32 species were newly recorded for Beijing. Brachytheciaceae, Pottiaceae, Hypnaceae, Bryaceae, and Entodontaceae were the dominant families. Brachythecium, Entodon, Grimmia, Bryum, Pylaisia, Fissidens, Eurhynchium, and Trichostomum were the dominant genera. Analysis of the geographical elements of the bryophytes showed that the North Temperate element was dominant (36.7%), followed by the East Asia element (18.0%). Based on the principal component analysis (PCA) of the main components of bryophytes in 15 regions of China, we found that the bryophytes of Dongling Mountain were most similar to those of Wuling Mountain, Xiaowutai Mountain and Helan Mountain, and closest to those of Yunmeng Mountain.
