Comparative Transcriptomic Analysis Revealed Adaptation Mechanism Of
Yang et al. BMC Evolutionary Biology (2015) 15:101 DOI 10.1186/s12862-015-0371-8 RESEARCH ARTICLE Open Access Comparative transcriptomic analysis revealed adaptation mechanism of Phrynocephalus erythrurus, the highest altitude Lizard living in the Qinghai-Tibet Plateau Yongzhi Yang1†, Lizhong Wang1†, Jin Han1, Xiaolong Tang2, Ming Ma2, Kun Wang1, Xiao Zhang1, Qian Ren1, Qiang Chen2 and Qiang Qiu1* Abstract Background: 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 candidate genes under positive selection and to explore the convergent evolutionary adaptation of poikilothermic animals to high altitude life. Results: More than 70 million sequence reads were generated for each species via Illumina sequencing. De novo assembly produced 56,845 and 63,140 transcripts for P. erythrurus and P. putjatia, respectively. P. erythrurus had higher Ka/ Ks ratios than P. putjatia, implying an accelerated evolutionary rate in the high altitude lizard lineage. 206 gene ontology (GO) categories with accelerated evolutionary rates and 43 candidate positively selected genes were detected along the P. erythrurus lineage. Some of these GO categories have functions associated with responses to hypoxia, energy metabolism and responses to UV damage. We also found that the high-altitude ranid frog R. kukunoris had higher Ka/Ks ratios than the closely related low-altitude frog R. -
Movement and Habitat Use by Adult and Juvenile Toad-Headed Agama Lizards (Phrynocephalus Versicolor Strauch, 1876) in the Eastern Gobi Desert, Mongolia

When a lizard was small lizard (Agamidae) found in desert and semi- sighted, we captured the animal by hand or noose. desert regions of China, Mongolia, Kazakhstan and We then measured the lizard (snout-to-vent length Kyrgyzstan (Zhao, 1999). The species inhabits areas of (SVL; mm) and mass (g) and sexed adults by probing. sparse vegetation and can be relatively common, with Juveniles were too small to sex.

We measured males and females to determine whether this species exhibits sexual size dimorphism and whether there was a correlation between feeding ecology and body size. We also examined spatiotemporal and sexual variations in dietary composition and prey diversity index. We used these data to examine whether the foraging pattern of these skinks corresponded to the pattern of a sit-and-wait predator or a widely foraging predator. The average snout-vent length (SVL) was significantly larger in adult males than in adult females. When SVL was taken into account as a covariate, head length and width and mouth width were larger in adult males than in adult females. -
Genetic Signatures of High-Altitude Adaptation and Geographic
www.nature.com/scientificreports OPEN Genetic signatures of high‑altitude adaptation and geographic distribution in Tibetan sheep Jianbin Liu1,2*, Chao Yuan1,2, Tingting Guo1,2, Fan Wang3, Yufeng Zeng1, Xuezhi Ding1, Zengkui Lu1,2, Dingkao Renqing4, Hao Zhang5, Xilan Xu6, Yaojing Yue1,2, Xiaoping Sun1,2, Chune Niu1,2, Deqing Zhuoga7* & Bohui Yang1,2* Most sheep breeding programs designed for the tropics and sub‑tropics have to take into account the impacts of environmental adaptive traits. However, the genetic mechanism regulating the multiple biological processes driving adaptive responses remains unclear. In this study, we applied a selective sweep analysis by combing 1% top values of Fst and ZHp on both altitude and geographic subpopulations (APS) in 636 indigenous Tibetan sheep breeds. Results show that 37 genes were identifed within overlapped genomic regions regarding Fst signifcantly associated with APS. Out of the 37 genes, we found that 8, 3 and 6 genes at chromosomes (chr.) 13, 23 and 27, respectively, were identifed in the genomic regions with 1% top values of ZHp. We further analyzed the INDEL variation of 6 genes at chr.27 (X chromosome) in APS together with corresponding orthologs of 6 genes in Capra, Pantholops, and Bos Taurus. We found that an INDEL was located within 5′UTR region of HAG1 gene. This INDEL of HAG1 was strongly associated with the variation of APS, which was further confrmed by qPCR. Sheep breeds carrying “C‑INDEL” of HAG1 have signifcantly greater body weight, shear amount, corpuscular hemoglobin and globulin levels, but lower body height, than those carrying “CA‑INDEL” of HAG1. -

ABSTRACT According to field observations made in 1996-2003, the Volga region populations of the Spotted Toad- headed Agama Phrynocephalus guttatus (GMELIN, 1789) prefer fixed and weakly fixed sands with sparse bush and gras vegetation. Analysis of Russian and Ukrainian museum specimens revealed that the populations on the Don sands in the Volgograd region belong to Ph. g. guttatus. However, they are specific by some metric characteristics due to their outlying position in the north of the species' range area.

The Spatio-Temporal Characteristics of the Coordinated Development Of
2019 International Conference on Power, Energy, Environment and Material Science (PEEMS 2019) ISBN: 978-1-60595-669-5 The Spatio-Temporal Characteristics of the Coordinated Development of Urbanization and Resources Environmental Carrying Capacity in Lanzhou-Xining Urban Agglomeration Wei-ping ZHANG and Pei-ji SHI* School of Geography and Environmental Sciences, Northwest Normal University, Lanzhou 730070, P.R. China *Corresponding author Keywords: Urbanization, Resource environmental carrying capacity, Coordination characteristics, Temporal and spatial patterns, Lanzhou-Xining urban agglomeration. Abstract. The coordination of urbanization and resources and environment is one of the key issues to promote regional social and economic development. This paper took Lanzhou-Xining urban agglomeration as the study area, constructed the evaluation index of urbanization and resource environmental carrying capacity first, and then used entropy method and the coordination degree model to measure the coordination of urbanization and resource environmental carrying capacity from 2005 to 2017. Results indicate that the overall index of urbanization and resource environmental carrying capacity of Lanzhou-Xining urban agglomeration shows an upward trend, and there are obvious spatial differences, especially between Lanzhou and Xining and the surrounding counties. The coordination degree of urbanization and resource environmental carrying capacity is between [0.5, 0.6), most of the counties are in a state of reluctance coordination, and the spatial distribution law of the degree is high in the east and low in the west. And the regional differences are gradually shrinking. There is a significant positive correlation between urbanization and capacity. The coordination status of Lanzhou and Xining provincial cities is relatively good, and the urbanization level is lower.
