| sequencing and phylogenetic analysis of the pyrgilauda ruficollis (aves, passeridae) complete mitochondrial genome. | in this study, both long pcr and conserved primers walking sequencing methods were used to determine the complete sequence of the of pyrgilauda ruficollis mitochondrial genome (kc836121). the results showed that the complete mitochondrial genome of p. ruficollis is 1 6909 bp in length with 55.0% a+t content, harboring the typical 37 genes. the mitogenome had the same gene order with that of podoces hendersoni. all protein coding genes started with atg codon, except nd3 with gtg. for the stop cod ... | 0 | 24668650 |
| complete mitochondrial genome of the onychostruthus taczanowskii (aves, passeridae) and its phylogenetic analysis. | the complete mitochondrial genome sequence of onychostruthus taczanowskii consisted 16 917 bp, the genome harbored the same gene order with that of other birds, contained 13 protein-coding genes, 22 trnas, 2 rrnas and 1 non-coding control region. the all trnas formed typical cloverleaf secondary structures, except trna(ser (agn)) and trna(phe). the control region was located between trna(glu) and trna(phe) with 1310 bp in length, which consist of three domains: highly variable domain i, central ... | 2016 | 26153747 |
| postglacial colonization of the tibetan plateau inferred from the matrilineal genetic structure of the endemic red-necked snow finch, pyrgilauda ruficollis. | most phylogeographical studies of postglacial colonization focus on high latitude locations in the northern hemisphere. here, we studied the phylogeographical structure of the red-necked snow finch pyrgilauda ruficollis, an endemic species of the tibetan plateau. we analysed 879 base pairs (bp) of the mitochondrial cytochrome b gene and 529 bp of the control region in 41 birds from four regional groups separated by mountain ranges. we detected 34 haplotypes, 31 of which occurred in a single indi ... | 2005 | 15836648 |
| coping with extremes: convergences of habitat use, territoriality, and diet in summer but divergences in winter between two sympatric snow finches on the qinghai-tibet plateau. | on the qinghai-tibet plateau, extreme environmental conditions have imposed intense selective pressure on the evolution of phenotypic traits of wild animals. to date, limited information is available on behavioral and ecological traits concerning niche differentiation among sympatric animals on the qinghai-tibet plateau, especially during winter when the environments are most severe. here, we studied the seasonal variations in habitat occurrence, territorial behavior, and diet in two sympatric s ... | 2020 | 32627943 |
| coping with extremes: remarkably blunt adrenocortical responses to acute stress in two sympatric snow finches on the qinghai-tibet plateau during winter relative to other seasons. | the extreme climatic conditions (eccs) of the qinghai-tibet plateau impose strong selective pressures on the evolution of phenotypic traits in free-living animals. it is not well understood how animals on the qinghai-tibet plateau modify their adrenocortical functions in response to both predictable and unpredictable events of eccs, especially when the available resources are lowest during the wintering life-history stage. to uncover potential physiological mechanisms, we studied the life histor ... | 2020 | 32057911 |
