isolation and characterization of microsatellites in chinese soft shelled turtle pelodiscus sinensis
Molecular Ecology Notes, 2007Co-Authors: Yanfu Que, Bin Zhu, H Rosenthal, J ChangAbstract:Fifteen polymorphic microsatellite loci were developed for the Chinese soft-shelled turtle (Pelodiscus sinensis) from the (GT)(n) microsatellite-enriched genomic library, using the fast isolation by amplified fragment length polymorphism of sequences containing repeats protocol. The polymorphism of all 15 loci ranged from two to seven alleles with observed heterozygosities ranging from 0.03 to 0.98 (mean 0.43) in one population of 40 individuals. These novel loci will be helpful for understanding the population structure at genetic level and marker-assisted breeding of this Vulnerable Species.

winter diet and food selection of the black necked crane grus nigricollis in dashanbao yunnan china
PeerJ, 2016Co-Authors: Hao Yan Dong, Xing Yao Zhong, Xiaojun YangAbstract:The Black-necked Crane Grus nigricollis is a globally Vulnerable Species whose food is the factor determining its long-term survival. Understanding dietary habits, food preferences, and related factors will facilitate the development of effective conservation plans for the protection of this Vulnerable Species. For this purpose, we used video recordings and sampling of food availability to examine the dietary composition and temporal variation in food selection of Black-necked Cranes wintering in the Dashanbao National Nature Reserve, China. The Black-necked Crane's diet consists primarily of domestic food crops such as grains (74%) and potatoes (8%), in addition to invertebrates (14%). A much smaller proportion of the diet was comprised of turnips and wild herbaceous plants and tubers. There was monthly variation in food selection, partially related to food availability. Grains were most available in November and decreased through the winter, whereas invertebrates were more available in November and February than in December and January. Grain consumption was lowest in November but higher from December through February. Invertebrate consumption was highest in November and February. The cranes preferred to eat grains throughout winter months, while they mainly selected invertebrates in November and February. We suggested invertebrate populations sharply declined in December and January due to the low temperature. In addition, grain consumption was negatively associated with invertebrate availability. In November, when invertebrates were most abundant, and despite a concomitant peak in grain abundance, we suggested cranes exhibited a preference for invertebrates over grains. We recommend that the protection administration provide appropriate supplemental foods for cranes during freezing weather.

satellite tracking reveals a new migration route of black necked cranes grus nigricollis in qinghai tibet plateau
PeerJ, 2020Co-Authors: Ye Wang, Yumin GuoAbstract:Background The black-necked crane (Grus nigricollis) is a Vulnerable Species and the only Species that lives in the plateau. Five migration routes of different populations have been identified, but for cranes wintering in Nyingchi Prefecture, Tibet, the migration route and breeding/summering area are still unknown. The aim of this study was to investigate the spatio-temporal migration patterns of black-necked cranes in this area and to identify important areas for conservation. Methods In 2016, we fitted seven black-necked cranes in Nyingchi with GPS-GSM satellite transmitters to record their migration routes. We used ArcGIS 10.2 to visualize important stopover sites and the 'ggplot' function in R to analyze the migration patterns. Results From March 2016 to May 2019, we recorded nine spring migration and four autumn migration tracks from five individuals. Four individuals spent the breeding/summering season in Qinghai Lake, while the other spent the breeding/summering season in the Jinzihai Wetland of Dulan County, Qinghai Province. Detailed spatio-temporal information showed that the spring migration lasted 8.7 ± 4.6 days and covered 1,182.5 ± 90.4 km, while the autumn migration lasted 30 ± 10.6 days and covered 1,455.7 ± 138 km. Basom Lake and the Shazhuyu River were the most important stopover sites during the spring and autumn migrations, respectively. The cranes spent 4.4 ± 3.7 days in Basom Lake and 26.3 ± 10.7 days in the Shazhuyu River. The black-necked cranes mainly migrated during the daytime (>85 % of the fly points), and 81 % (17/21) of all stopover and roosting sites were in the valley or at lakeside swamps. Only 17.7% (516 / 2,914) of the data points for stopover and roosting sites were in protected areas. Main conclusions Our study revealed the breeding/summering areas and migration routes of the black-necked cranes wintering in Nyingchi. These results contribute to a better understanding of the annual spatio-temporal migration patterns and the development of conservation plans for this Vulnerable Species.
