Effect of environmental change on species diversity of bryophytes: a case study in Xujiahui (Zi ka Wei) area, Shanghai


Abstract:
Based on literature, preserved specimens and field investigation, we compared species diversity and composition of bryophytes in the Xujiahui area of Shanghai between the early of 20th and 21th centuries. A total of 24 bryophyte species were recorded in this area between 1906 and 1910. Of these, 15 were described as new species, however only 6 species and 1 variety are currently still accepted as valid species. On the other hand, 21 bryophyte species were found in the area during this investigation. During the past 100 years, there were no distinct effects of environmental change on bryophyte diversity; however, bryophyte species composition changed almost completely. Besides one, Plagiomnium acutum, we found none of the type species reported in the early of 20th century from Xujiahui. The number of small and ground bryophyte species, including Bryaceae and Funariaceae species, increased, whereas epiphytic bryophyte decreased. Some cosmopolitan species with good resistance to human disturbance became more common. We propose suggestions for bryological conservation in urban areas.
