molecular characterization of cryptosporidium from animal sources in qinghai province of china.the presence of cryptosporidium oocysts in 20 zoo animals of the xining zoo, 16 farm yaks and 42 farm goats in qinghai province, china was investigated by an immunofluorescence test (ift). the species and/or genotypes were determined by nested polymerase chain reaction (pcr) and sequence analysis of a fragment of the small subunit (ssu) rrna gene. cryptosporidium oocysts were found in 16 zoo animals, 2 yaks, and 15 goats by ift. the ift positive samples were further investigated by pcr, and 16 o ...200717701218
plasmodium (bennettinia) juxtanucleare infection in a captive white eared-pheasant (crossoptilon crossoptilon) at a japanese adult male white eared-pheasant (crossoptilon crossoptilon) at a japanese zoo exhibited lethargy and emaciation. microscopic examination of a blood smear revealed a haemosporidian parasitic infection. based on the morphological characteristics and molecular analysis of the parasite, it was identified as plasmodium (bennettinia) juxtanucleare. this is the first report of p. juxtanucleare infection in bird species belonging to the genus crossoptilon. caution against avian malaria infection is r ...200818319584
assessment of genetic diversity in chinese eared pheasant using fluorescent-aflp markers.the eared pheasant consists of four species: white eared pheasant (crossoptilon crossoptilon), tibetan eared pheasant (crossoptilon harmani), blue eared pheasant (crossoptilon auritum), and brown eared pheasant (crossoptilon mantchuricum). these species are found only in china, and are also on the list of the world's threatened species. in this paper, 74 individuals from the four eared pheasant species were assessed for population genetic diversity by means of fluorescent-aflp markers. a total o ...201020595068
glaciation-based isolation contributed to speciation in a palearctic alpine biodiversity hotspot: evidence from endemic species.organisms are unevenly distributed on earth and the evolutionary drivers of that have puzzled ecologists and evolutionary biologists for over a century. even though many studies have focused on the mechanisms of unevenly distributed fauna and flora, there remains much to learn about the evolutionary drivers behind biodiversity hotspots. in the tibetan plateau and hengduan mountains, a biodiversity hotspot in the palearctic realm, alpine uplift cannot be the driver for recent speciation (<two mil ...201830218774
