Data set of ecological resource consumption in Tibet (2000-2019)

The ecological resource consumption data set of Tibet includes the ecological resource consumption data of 2000-2019 at the provincial, city and county levels. According to the actual situation of Tibet, ecological resource consumption mainly refers to the amount of ecological resources consumed in agricultural and animal husbandry production activities. The calculation of ecological resource consumption is based on grain production data, livestock stock data and livestock product production data, combined with the evaluation method of human appropriation the net primary productivity (HANPP), convert biomass data into carbon content data, and then calculate the ecological resource consumption. Ecological resource consumption data is the basic data for the study of ecological pressure and ecological carrying capacity, which can directly reveal the pressure of human agricultural and animal husbandry production activities on the ecosystem.

Data of lake benthos in Tibet (2019)

This data includes the benthos data of 21 lakes around Selinco and Namco in 2019. The sampling mainly uses bottom trawl in the littoral zone and Ekman collector in the deep-water area. After integrating the materials obtained by the two ways, the relative abundance of benthos data of each lake is given. The main benthos species are Gammarus, water beetles, and chironomid larvae. However, the frequency of Gastropoda and Ostracoda is low, which may be related to the sampling sites. The data further divided different types of benthos into 21 taxa, which improved the recognition accuracy and cognitive range and would provide a reference for the assessment of aquatic animal diversity and fishery resources in plateau lakes.

Tracking data of Wintering Black necked Crane population in Central Yunnan Province (2017)

We used satellite tracking technology to track some wintering populations of black necked Crane. After catching the black necked Crane with the foot buckle method, we fixed the tracker with backpack method. The total weight of the tracker is 45g, accounting for less than 1% of the weight of the black necked Crane. After flying, we get the tracking data of the black necked Crane by sampling comments of one activity point per hour, and draw these data on the map, so as to obtain the activity track of the black necked Crane during the winter. The results showed that the selection of wintering sites for black necked cranes was highly stable. Preliminary analysis showed that there was a strong link between wintering sites and breeding sites. Strong migration connectivity indicates that black necked cranes are more vulnerable to environmental changes. These results suggest that it is important to strengthen the protection of overwintering habitat. At the same time, we need to take a variety of methods to monitor the population health and dynamics of black necked Crane. This data set contains species name, location, time, longitude and latitude, altitude, speed, temperature and other information.

DNA methylation and transcriptome data of Plateau Zokor (2020)

Plateau Zokor (Eospalax) Baileyi is an animal of mole family and zokor genus. It lives in underground dark closed caves for a long time and does not hibernate. It mainly feeds on the underground roots of plants. It reproduces once a year and produces 1-6 pups per litter. It mainly inhabits in humid river terraces, mountain basins, beaches and Foothills such as alpine meadow, meadow grassland, alpine shrub, plateau farmland and barren slope Slope, only distributed in Western and Northwest China, 2800-4500m above sea level. The plateau zokor distributed in high altitude area not only faces the hypoxia stress of underground cave, but also faces the dual pressure of plateau hypoxia. Long term hypoxic life not only accumulates adaptive mutations in genome sequence, but also reflects adaptive regulation changes in genome structure and gene expression regulation. By analyzing DNA methylation and transcriptome data of Plateau Zokor at different altitudes, we can try to analyze the adaptive evolution and regulation mechanism of Plateau Zokor at the level of apparent regulation and gene expression.
