A Study on Distribution Pattern of An Epiphytic Bryophyte, Dolichomitriopsis diversif ormis ( Lembophyllaceae) on Tree Trunks in Forest in Fanjing Mountain of Guizhou

Abstract

Abstract:

The distribution pattern of Dolichomitriopsis diversif ormis (Mitt. ) Nog. in Fanjing Mountain of Guizhou was investigated
by means of TWINSPAN and DCA. The results showed that the community-wide distribution of epiphytic D1 diversif
ormis is well correlated with forest community types. The forest communities with this species can be divided into six
groups, which are Cyclobalanop sis stewardiana-Sinarundinaria nitida community, Cyclobalanopsis stewardiana+ Quercus
engleriana+ Carpinus viminea-Sinarundinaria nitida community, Cyclobalanopsis stewardiana-Euryia brevistyla commun-i
ty, Rhododendron ririei + Cyclobalanop sis multinervis-Illicium simonsii community , Fagus lucida + Cyclobalanopsis
multinervis+ Cyclobalanopsis stewardiana-Sinarundinaria nitida community and Cyclobalanop sis stewardiana-Camellia cuspidata-
Illicium simonsii community respectively. The vertical distributive range of this species is 1 650- 2 080 m above sea
level; the vertical distribution of this species on tree trunks is that on the lower parts are significantly more than on the
middle parts and on the middle parts are significantly more than on the upper parts; the distribution of this species among
different tree species is remarkably different. The ecological factors of influencing the distribution of epiphytic D1 diversif
ormis in Fanjing Mountain were also analyzed and discussed.

Key words: Dolichomitriopsis diversif ormis , Epiphytic bryophyte, Distributive pattern, DCA, TWINSPAN
