| mitogenome of fejervarya multistriata: a novel gene arrangement and its evolutionary implications. | in this study, we determined the complete nucleotide sequence of the mitochondrial (mt) dna of the paddy frog fejervarya multistriata. mtdna is 17,750-bp long and contains 13 protein-coding regions, 2 ribosomal rna, non-coding genes, and 23 trna because of the presence of an extra copy of trna-met. the gene arrangements among two related species of fejervarya were compared, and the combined mtdna data were subjected to a phylogenetic analysis. interestingly, we observed a unique translocation of ... | 2016 | 27706580 |
| phylogeography of the rice frog, fejervarya multistriata (anura: ranidae), from china based on mtdna d-loop sequences. | the rice frog, fejervarya multistriata, is an amphibian widely distributed in china. in this study, we sampled the species across its distributional area in china and sequenced the mtdna d-loop to investigate the genetic diversity and geographical pattern of the frog population. the results revealed 38 haplotypes in the population, with k2p values varying from 0.19% to 4.22%. both a phylogenetic analysis and a nested clade analysis (nca) detected two geographically isolated lineages respectively ... | 2008 | 18795815 |
| [effects of environmental factors on the distribution of amphibians in agricultural landscape]. | we analyzed the relationship between the distribution of amphibians and the environmental variables at the habitat level and landscape level in fengqiu county of henan province, a typical region of the lower reaches of the yellow river, with the support of geographic information system (gis) and r software. at the habitat level, dissolved oxygen (do), conductivity (cond), turbidity (turb), nh3-n, pond-interior vegetation cover (veginterior), emergent vegetation cover (emer), pond-edge vegetation ... | 2019 | 30907553 |
| algicidal efficiency and genotoxic effects of phanerochaete chrysosporium against microcystis aeruginosa. | eutrophication has become a severe environmental problem. this study evaluated the algicidal efficiency and genotoxic effects of microcystis aeruginosa co-cultured with phanerochaete chrysosporium for 48 h under the optimum conditions of 250 mg/l of p. chrysosporium at 25 °c with dissolved oxygen content of 7.0 mg/l. the results showed that the activity of algal dehydrogenase, superoxide dismutase, and peroxidase were all decreased and the malondialdehyde content increased after co-culturing. fo ... | 2020 | 32517048 |
