Abstract

Abstract:

Herbaria can provide important information about the spatial distribution of plants, and are important data sources for estimating species richness. In this study we described elevational patterns of specimen frequencies and species richness of seed plants above timber line in the Hengduan Mountains and discussed the impact of specimen data on the estimation of species richness. Specimen data came from the online database ( http://hengduan.huh.harvard.edu) and herbaria. Elevations above timber line were divided into fourteen 100-m belts, and the frequencies of specimens in each elevational belt were recorded. There were 1,820 species and 8,316 specimens with elevational information, of which 655 species were endemic to this region. Distribution of specimens among species was extremely uneven. For example, 974 species (about 53.5% of total species) were represented by 1-2 specimens. Total and average number of specimens in elevational belts decreased linearly with the increasing elevation. Species richness also decreased with the increasing elevation, but species rarefaction curves were not useful for describing elevational patterns in species richness. We suggest that more field plot-sampling and specimen collections are needed to accurately estimate species richness.
