effect of anthropogenic landscape features on population genetic differentiation of przewalski's gazelle: main role of human settlement.anthropogenic landscapes influence evolutionary processes such as population genetic differentiation, however, not every type of landscape features exert the same effect on a species, hence it is necessary to estimate their relative effect for species management and conservation. przewalski's gazelle (procapra przewalskii), which inhabits a human-altered area on qinghai-tibet plateau, is one of the most endangered antelope species in the world. here, we report a landscape genetic study on przewa ...201121625459
identification of ungulates used in a traditional chinese medicine with dna barcoding technology.horns of saiga antelope (saiga tatarica) have always been an ingredient of "lingyangjiao", a traditional chinese medicine (tcm). persistent hunting for saiga antelope has already threatened the survival of critical endangered populations in wild. to control the growing pressure, cites and chinese government have legislated for monitoring the trade of saiga horns. however, similar ungulate horns are difficult to identify by their morphological characteristics, which has impeded the law enforcemen ...201526140198
genetic diversity and population structure of a sichuan sika deer (cervus sichuanicus) population in tiebu nature reserve based on microsatellite variation.cervus sichuanicus is a species of sika deer (cervus nippon group). to date, research has mainly focused on quantity surveying and behavior studies, with genetic information on this species currently deficient. to provide scientific evidence to assist in the protection of this species, we collected sichuan sika deer fecal samples from the sichuan tiebu nature reserve (tnr) and extracted dna from those samples. microsatellite loci of bovine were used for pcr amplification. after genescan, the gen ...201425465089
detecting the potential sympatric range and niche divergence between asian endemic ungulates of procapra.species distribution modeling (sdm) is increasingly used to reveal biogeographical relationships, for example the sympatric range for species coexistence, and fundamental questions about niche evolution between related species. we explored the sympatric ranges between three procapra species (procapra przewalskii, procapra picticaudata, and procapra gutturosa) via two methods of defining the study region (method 1, in which models were developed in a larger region including the whole geographic r ...201222743804
effect of group size and reproductive status on faecal glucocorticoid concentration and vigilance in a free-ranging population of przewalski's gazelle.elevated glucocorticoid (gc) concentration and increased vigilance are two common responses to predation risk in mammals. chronic high-level gc concentration and vigilance occur at the expense of other life maintenance and reproduction activities, reflecting a trade-off between individual survival and future fecundity. przewalski's gazelle (procapra przewalskii) is a group-living ungulate endemic to the high-altitude qinghai lake region of china. group-size effect on gazelle vigilance has been e ...202032274069
responses of przewalski's gazelle (procapra przewalskii) to zinc nutrition in physical habitat.to study responses of procapra przewalskii to zinc (zn) nutrition in physical habitat, we analyzed the content of mineral elements in soil, forage, and animal tissues. physiological and biochemical indexes were also determined. the results showed that zn contents in the soil and forage from affected pasture were significantly lower (pā€‰<ā€‰0.01) than those in unaffected areas. zn concentrations in the blood, liver, and hair from affected p. przewalskii were also significantly lower (pā€‰<ā€‰0.01) than ...202032236846
effects of selenium-deprived habitat on the immune index and antioxidant capacity of przewalski's gazelle.przewalski's gazelle (procapra przewalskii) is an endangered ungulate in the qinghai-tibet plateau of china. this study aimed to determine the influence of selenium (se) deprivation in the natural habitat on the immune index and antioxidant capacity of p. przewalskii. samples of soil and forage were collected from affected and healthy areas, and animal tissues were collected from affected and healthy p. przewalskii. the samples were used for measuring mineral content and for hematological and bi ...202032040847
epidemic and evolutionary characteristics of peste des petits ruminants virus infecting procapra przewalskii in western china.due to the migration or transboundary spread of domestic and wild animals, peste des petits ruminants virus posed a high potential threat to them. in this study, we initially detected that a class of animal named procapra przewalskii was infected with peste des petits ruminants virus (pprv chinags2018) in gansu province. according to phylogenetic relationships analysis, we found that chinags2018 comprised of 15,954 nucleotides and was classified into iv genotypes. in addition, indirect immunoflu ...201931415822
effects of the qinghai-tibet railway on the landscape genetics of the endangered przewalski's gazelle (procapra przewalskii).the przewalski's gazelle (procapra przewalskii) is one of the most endangered ungulates in the world, with fewer than 2,000 individuals surviving in nine habitat fragments on the qinghai-tibet plateau and isolated by human settlements and infrastructure. in particular, the qinghai-tibet railway, which crosses the largest part of the gazelle's distribution, remains a major concern because of its potential to intensify landscape genetic differentiation. here, using mtdna sequencing and microsatell ...201729269860
intestinal parasites in the critically endangered przewalski's gazelle ( procapra przewalskii ) in china, with the description of a new species of eimeria (apicomplexa: eimeriidae).we used a flotation technique to survey fecal samples from 27 przewalski's gazelles ( procapra przewalskii büchner, 1891) for intestinal parasites. samples were collected from the qinghai lake region, qinghai-tibet plateau, china, in april 2015. we report parasites belonging to two nematode (nematodirus, marshallagia) genera and one apicomplexan (eimeria) genus; one of the latter was a new species from the critically endangered przewalski's gazelle. sporulated oocysts of the new eimerian were sp ...201627458832
a spatially explicit model of functional connectivity for the endangered przewalski's gazelle (procapra przewalskii) in a patchy landscape.habitat fragmentation, associated with human population expansion, impedes dispersal, reduces gene flow and aggravates inbreeding in species on the brink of extinction. both scientific and conservation communities increasingly realize that maintaining and restoring landscape connectivity is of vital importance in biodiversity conservation. prior to any conservation initiatives, it is helpful to present conservation practitioners with a spatially explicit model of functional connectivity for the ...201324250829
effects of reproductive status, social rank, sex and group size on vigilance patterns in przewalski's gazelle.quantifying vigilance and exploring the underlying mechanisms has been the subject of numerous studies. less attention has focused on the complex interplay between contributing factors such as reproductive status, social rank, sex and group size. reproductive status and social rank are of particular interest due to their association with mating behavior. mating activities in rutting season may interfere with typical patterns of vigilance and possibly interact with social rank. in addition, balan ...201222389714
climate change hastens the conservation urgency of an endangered ungulate.global climate change appears to be one of the main threats to biodiversity in the near future and is already affecting the distribution of many species. currently threatened species are a special concern while the extent to which they are sensitive to climate change remains uncertain. przewalski's gazelle (procapra przewalskii) is classified as endangered and a conservation focus on the qinghai-tibetan plateau. using measures of species range shift, we explored how the distribution of przewalsk ...201121826214
