| the cold hardiness of phrynocephalus erythrurus, the lizard living at highest altitude in the world. | phrynocephalus erythrurus living at qinghai-tibet plateau, is believed to be the highest lizard in the world, but we know little about how these lizards cope with very low temperatures in winter. | 2017 | 28767745 |
| functional characterization and expression analysis of myoglobin in high-altitude lizard phrynocephalus erythrurus. | myoglobin (mb) is a monomeric hemoprotein which plays an important role in oxygen storage and transport in cardiac and skeletal muscle under hypoxia. the red tail toad-headed lizard phrynocephalus erythrurus (lacertilia: agamidae), which inhabits at an elevation of 4500-5300 m on the qinghai-tibetan plateau, is known to be the highest living lizard in the world. to investigate the characters of myoglobin of this unique species, another low altitude lizard phrynocephalus przewalskii (lacertilia: ... | 2015 | 26116966 |
| comparative transcriptomic analysis revealed adaptation mechanism of phrynocephalus erythrurus, the highest altitude lizard living in the qinghai-tibet plateau. | organisms living at high altitudes must overcome three major environmental challenges: hypoxia, cold, and intense uv radiation. the molecular mechanisms that enable these challenges to be overcome have mainly been studied in endothermic organisms; relatively little attention has been paid to poikilothermic species. here, we present deep transcriptome sequencing in two closely related lizards, the high altitude-dwelling phrynocephalus erythrurus and the lowland-dwelling p. putjatia, to identify c ... | 2015 | 26031664 |
| differences in hematological traits between high- and low-altitude lizards (genus phrynocephalus). | phrynocephalus erythrurus (lacertilia: agamidae) is considered to be the highest living reptile in the world (about 4500-5000 m above sea level), whereas phrynocephalus przewalskii inhabits low altitudes (about 1000-1500 m above sea level). here, we report the differences in hematological traits between these two different phrynocephalus species. compared with p. przewalskii, the results indicated that p. erythrurus own higher oxygen carrying capacity by increasing red blood cell count (rbc), he ... | 2015 | 25955247 |
| the complete mitochondrial genome of the subspecies, phrynocephalus erythrurus parva (reptilia, squamata, agamidae), a toad-headed lizard dwell at highest elevations of any reptile in the world. | the complete mitochondrial genome was sequenced from the toad-headed viviparous lizard subspecies, phrynocephalus erythrurus parva, which occupies the highest regions of any reptile on the earth. the mitogenome sequence was 16,431 bp in size, with the overall base composition of h-strand is t: 26.06%, c: 25.14%, a: 36.45%, g: 12.35%. it consists of 13 protein coding, 22 trna, 2 rrna genes and 3 control regions, and its gene order and gene content were identical with the published congeneric mito ... | 2016 | 24810070 |
| metabolic characteristics and response to high altitude in phrynocephalus erythrurus (lacertilia: agamidae), a lizard dwell at altitudes higher than any other living lizards in the world. | metabolic response to high altitude remains poorly explored in reptiles. in the present study, the metabolic characteristics of phrynocephaluserythrurus (lacertilia: agamidae), which inhabits high altitudes (4500 m) and phrynocephalusprzewalskii (lacertilia: agamidae), which inhabits low altitudes, were analysed to explore the metabolic regulatory strategies for lizards living at high-altitude environments. the results indicated that the mitochondrial respiratory rates of p. erythrurus were sign ... | 2013 | 23951275 |
| phylogeography of phrynocephalus erythrurus from the qiangtang plateau of the tibetan plateau. | phrynocephalus erythrurus of the qiangtang plateau occupies the highest regions of any reptile on earth. here, we report mitochondrial dna haplotypes sampled throughout the distribution of p. erythrurus and analyze patterns of genetic divergence among populations. the species diverged into two major lineages/subspecies at 3.67mya corresponding to the northern and southern qiangtang plateau. the northern qiangtang lineage diverged into two subpopulations at 2.76mya separated by the beilu river re ... | 2010 | 19900565 |
| the response of nitric oxide system to high altitude in phrynocephalus erythrurus on qinghai-tibetan plateau. | nitric oxide (no), produced by nitric oxide synthases (nos) from l-arginine, plays important roles in a wide range of physiological processes. however, little is known about ectothermic species. to investigate the response of no/nos system in adaptation to different altitudes in phrynocephalus genus, the red tail toad-headed lizard phrynocephalus erythrurus that live at 4500-5300 m on the qinghai-tibet plateau and another low altitude living lizard phrynocephalus przewalskii were selected in the ... | 2019 | 30690199 |
