Species diversity of bryophytes on Dajinshan Island, Shanghai

doi:10.3969/j.issn.1000-5641.2024.04.008

Abstract

Abstract:

The aim of this study was to update the bryophyte list of Dajinshan Island and provide the scientific basic data for in situ conservation. Based on five field investigations on the island, 67 species belonging to 38 genera in 20 families are reported herein. Compared with historical data for Dajinshan Island, 23 species are newly recorded in the island. Of these, 13 species are newly recorded in Shanghai. One epiphyllous liverwort species, Cololejeunea raduliloba Steph., is newly reported on Dajinshan Island. Taking into account climate change and the physiological and ecological characteristics of bryophytes, the changes in bryophyte species composition on Dajinshan Island are discussed. Our results highlight the importance of timely updating of a regional checklist, when conserving bryophyte biodiversity.

Key words: species checklist, new records, epiphyllous liverworts, climate change
