Qinghai Tibet Plateau

The biodiversity of fungi, which are extremely important in maintaining the ecosystem balance in alpine lakeside wetlands, has not been fully studied. In this study, we investigated the fungal communities of three lakeside wetlands from different altitudes in the Qinghai–Tibet Plateau and its edge. The results showed that the fungi of the alpine lakeside wetland had higher species diversity. Functional annotation of fungi by FUNGild software showed that saprophytic fungi were the most abundant type in all three wetlands. Further analysis of the microbial phylogenetic molecular ecological network (pMEN) showed that saprophytic fungi are important species in the three wetland fungal networks, while symbiotic fungi and pathotrophic fungi have different roles in the fungal networks in different wetlands. Community diversity was high in all three lakeside wetlands, but there were significant differences in the composition, function and network structure of the fungal communities. Contemporary environmental conditions (soil properties) and historical contingencies (geographic sampling location) jointly determine fungi community diversity in this study. These results expand our knowledge of fungal biodiversity in the alpine lakeside wetlands.

The Upper Yangtze River

The Dingqu River Basin, a major tributary of the upper Yangtze River, is located at southeast edge of the Qinghai-Tibet Plateau of China. The fishes of this plateau constitute a major faunal component of this basin, particularly Schizothoracinae (Cypriniformes: Cyprinidae) and Triplophysa (Cypriniformes: Nemacheilidae). Hydropower development is an impact that affects natural habitats and biological resources of the upper Yangtze River and this has led to a decrease in biodiversity. This study investigated the species diversity of fishes of the Dingqu River Basin and accumulated basic data for conservation of biodiversity and assessment of ecological health of the upper Yangtze River. The upper streams of the Jinshajiang River harbours numerous endemic fish species in China. Most of them belong to the Qianghai-Tibet Plateau fish fauna. However, while the fish species of the Jinshajiang River have been well studied, there is still a gap in the research on fish species diversity of the Dingqu River Basin tributary. This study provides information for 18 native fish species belonging to two orders, four families, three subfamilies and eight genera, and is the first complete record of fishes in the Dingqu River Basin, a primary tributary of the Yangtze River. Supplemental information of species diversity in the Jinshajiang River is also provided. The study includes two datasets, which present taxonomic, distribution, habitat condition, endemism and threat information for each species collected from the Dingqu River Basin and historical literature, respectively. In particular, these fish species all have limited distribution within the south-eastern Qinghai-Tibet Plateau areas of China and could determine the importance of habitat protection for the upper Yangtze River.

Gentiana Crassicaulis

Gentiana section Cruciata (Gentianaceae) is mainly found on alpine mountains across Eurasia, with the greatest species diversity occurring on the Qinghai–Tibet Plateau. Gentiana crassicaulis Duthie ex Burk. and the closely related species Gentiana robusta King ex Hook. f. and Gentiana tibetica King ex Hook. f. in sect. Cruciata show extremely high morphological similarity, which could be one of the main reasons for their misidentification. This study targets the authentication of the three closely related species in section Cruciata using morphometric analysis of flower shape. We collected 130 individuals in 14 populations of G. crassicaulis, 38 individuals in 12 populations of G. tibetica, and 45 individuals in 13 populations of G. robusta throughout the respective geographical ranges of the species. We used the parameters for bract length (l1), bract width (w1), inflorescence circumference (c), inflorescence width (w2), calyx length (l2), and corolla length (l3) to quantify the flower shape. The analyses showed that the parameters Rb (l1/w1), Ri (w1/w2), and l3 were significantly different between two of the species: G. crassicaulis and G. tibetica could be identified through corolla length, and although very similar to G. crassicaulis and G. tibetica, G. robusta is distinguishable using the parameters Rb and Ri.
