| survey for the amphibian chytrid batrachochytrium dendrobatidis in hong kong in native amphibians and in the international amphibian trade. | chytridiomycosis, caused by the pathogen batrachochytrium dendrobatidis, is responsible for many amphibian declines and has been identified in wild amphibian populations on all continents where they exist, except for asia. in order to assess whether b. dendrobatidis is present on the native amphibians of hong kong, we sampled wild populations of amolops hongkongensis, paa exilispinosa, p. spinosa and rana chloronota during 2005-2006. amphibians infected with b. dendrobatidis have been found in t ... | 2007 | 18286805 |
| interspecies introgressive hybridization in spiny frogs quasipaa (family dicroglossidae) revealed by analyses on multiple mitochondrial and nuclear genes. | introgression may lead to discordant patterns of variation among loci and traits. for example, previous phylogeographic studies on the genus quasipaa detected signs of genetic introgression from genetically and morphologically divergent quasipaa shini or quasipaa spinosa. in this study, we used mitochondrial and nuclear dna sequence data to verify the widespread introgressive hybridization in the closely related species of the genus quasipaa, evaluate the level of genetic diversity, and reveal t ... | 2018 | 29375796 |
| molecular phylogeny of megalobatrachonema (nematoda: ascaridida), with description of a new species based on morphological and molecular evidence. | species of megalobatrachonemayamaguti, 1941 (ascaridida: cosmocercoidea) are important nematode parasites in amphibians and reptiles. however, the phylogenetic relationship of its included two subgenera megalobatrachonema and chabaudgolvania remains unclear. in the present study, a new species of megalobatrachonema, m. (chabaudgolvania) wangi sp. nov., was described based on the specimens collected from the lesser spiny frog quasipaa exilispinosa (liu & hu) (amphibia: anura) in china. the riboso ... | 2020 | 31911143 |
