Abstract | [Objective] To study the characteristics of bryophytes in subalpine cold zone and related transition zone. [Method] The study was divided into scale A and scale B. On the scale of A, specimens were collected from Tongmai-Pailong-Dongjiu-Lulang-Sejila Pass-Nyingchi Town-Bagi Village along the national Highway 318. A sample plot was set for each 100 m altitude increase, and samples were collected between each two sample plots as well. On the scale of B, bryophyte specimens were collected and studied in the fixed sample plot of the Tibetan Nyingchi Alpine forest Ecosystem Research Observatory. [Result] Through the sampling and collection of bryophytes in Sejila Mountain, more than 3 000 specimens were identified with the classical classification method. There were 216 species of bryophytes belonging to 82 genera and 24 families. The bryophytes in the study area differed obviously in different vegetation types and slopes. The species richness of Sabina saltuaria-Abiesgeorgei var. smithii forest was the highest. The α diversity of Abiesgeorgei var. smithii forest was the highest, followed by Sabina saltuaria-Rhododendron forest, and that of alpine shrub was the lowest. Diversity studies showed that the β diversity of Sabina saltuaria-Rhododendron forest and Rhododendron forest on the eastern slope was the largest, and those of alpine shrub and Sabina saltuaria-Abiesgeorgei var. smithii forest were the lowest. However, the β diversity of Abiesgeorgei var. smithii forest on the western slope was the highest, and those of alpine shrub and Abiesgeorgei var. smithii forest were the lowest. [Conclusion] There are obvious differences in the distribution of bryophytes on the eastern and western slopes of Sejila Mountain of Tibet. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
