We reported data on thermal preference, thermal tolerance and the thermal dependence of digestive performance for two Phrynocephalus lizards （P. frontalis and P. versicolor）, and compared data among lizards so far studied worldwide. Mean values for selected body temperature （Tsel） and critical thermal maximum （CTMax） were greater in P versicolor, whereas mean values for critical thermal minimum （CTMin） did not differ between the two species. The two lizards differed in food intake, but not in food passage time, apparent digestive coefficient （ADC） and assimilation efficiency （AE）, across the experimental tem- peratures. Four general conclusions can be drawn from published data. Firstly, thermal preference and thermal tolerance differ among lizards differing in distribution, temporal activity pattern and habitat use. Lizards in thermally more variable regions are better able to tolerate low and high temperatures. Diurnal lizards generally select higher body temperatures than nocturnal lizards, and lizards using habitats with direct sun exposure generally selected higher body temperatures and are better able to tolerate high temperatures. Secondly, CTMax is positively correlated with Tsel. Lizards more likely exposed to extremely high temperatures while active select higher body temperatures than those using shaded habitats. Thirdly, the effects of body temperature on food intake, food passage time, ADC and AE differ among lizards, but it seems to be common among lizards that ADC and AE are less thermally sensitive than food intake and food passage time. Lastly, ADC is dependent on the type of food ingested, with insectivorous lizards digesting food more efficiently than herbivorous lizards

Isolation and Characterization of Nine Microsatellite Markers for Red-backed Ratsnake,Elaphe rufodorsata

引用

Asian Herpetological Research 2016年第3期7卷 227-228页

作者： Tianlong FU Shan SUN Chaonan ZHU yanfu qu Jiangsu Key Laboratory for Biodiversity and Biotechnology College of Life SciencesNanjing Normal University

The red-backed ratsnake（Elaphe rufodorsata） is widely distributed in East Asia, especially China. This species is a common snake in plain river network region. In the past several decades, E. rufodorsata has dramatically declined due to the effect of human activities and over hunting for traditional Chinese medicine. We developed nine species-specific microsatellite loci in 190 individuals collected from Huzhou, Zhejiang province in China. These markers revealed a high degree of genetic diversity（13–41 alleles per locus） and heterozygosity（H O ranged from 0.266 to 0.941, and H E ranged from 0.851 to 0.937）. No locus exhibited significant deviations from Hardy–Weinberg equilibrium. There was no evidence of linkage disequilibrium among pairs of loci. These microsatellite markers were described in our study will be valuable tools for the long term management and population-level studies（e.g. the population structure, genetic diversity and variation, individual paternity and evolutionary history） of the species.

Phylogeographic studies of Eremias lizards （Lacertidae） in East Asia have been limited, and the impact of major climatic events on their population dynamics remains poorly known. This study aimed to investigate population histories and refugia during the Last Glacial Maximum of two sympatric Eremias lizards （E. argus and E. brenchleyi） inhabiting northern China. We sequenced partial mitochondrial DNA from the ND4 gene for 128 individuals of E. argus from nine localities, and 46 individuals of E. brenchleyi from five localities. Forty-four ND4 haplotypes were determined from E. argus samples, and 33 from E. brenchleyi samples. Population expansion events began about 0.0044 Ma in E. argus, and 0.031 Ma in E. brenchleyi. The demographic history of E. brenchleyi indicates a long-lasting population decline since the most recent common ancestor, while that of E. argus indicates a continuous population growth. Among-population structure was significant in both species, and there were multiple refugia across their range. Intermittent gene flow occurred among expanded populations across multiple refugia during warmer phases of the glacial period, and this may explain why the effective population size has remained relatively stable in E. brenchleyi and grown in E. argus.

Identifying Intraspecific Variation in Venom Yield of Chinese Cobra(Naja atra) from Ten Populations in China's Mainland

引用

Asian Herpetological Research 2019年第1期10卷 32-40页

Detailed information on venom yield is helpful in preparing antivenoms and treating snakebites, but such information is lacking for many species of venomous snakes. The Chinese cobra(Naja atra) is a large sized, venomous snake commonly found in southeastern China, where it causes a heavy burden of snakebites. To examine the effects of various factors(morphology, sex, age, season, and geographical origin) on the venom yield in this snake, we collected venom samples of 446 individuals(426 adults and 20 neonates) from 10 populations of N. atra over an eightyear period. We used two variables, lyophilized venom mass(venom yield) and solid content of venom(% solids), to quantify the venom yield. We used linear regression analysis to check if venom yield was related to morphological factors, one-way ANOVA and one-way ANCOVA to detect the sexual, ontogenetic, and geographic variation in venom yield, and repeated-measures ANOVA to examine seasonal shifts in venom yield. Our results indicate that venom yield of N. atra is positively related to the morphological traits examined, with male snakes expelling more venom than females. Venom yield in N. atra was age-related, with elder snakes always expelling more venom than younger ones. Geographic variation in venom yield was also observed, while seasonal variation was not. The solid content of venom was lower in males than in females, but this was not related to morphology, season, age, or geography. Our findings suggest that venom yield in N. atra is influenced by multiple factors, as well as by the interactions among these factors.

Next-generation Sequencing of MHC Class Ⅰ Genes Reveals Trans-species Polymorphism in Eutropis multifasciata and Other Species of Scincidae

The genes of the major histocompatibility complex(MHC) encode cell surface proteins that are essential for adaptive immunity. MHC genes show the most prominent genetic diversity in vertebrates,reflecting the adaptation of populations to their evolving environment, population survival and reproduction. In the present study, we used nextgeneration sequencing(NGS) to study the loci polymorphism of exon 3 of the MHC class Ⅰ genes in an ovoviviparous skink, the many-lined sun skink,Eutropis multifasciata and five other species of Scincidae, to quantify genetic variation. In addition,we genotyped the same MHC class Ⅰ genes of *** using clone sequencing, to directly compare the effectiveness of both analytical techniques for MHC genotyping. NGS detected 20MHC class Ⅰ alleles in E. multifasciata, and 2 to 15 alleles in the other five Scincidae species. However,clone sequencing detected only 15 of those MHC class Ⅰ alleles in E. multifasciata. In addition, transspecies polymorphism of MHC class Ⅰ genes was studied by constructing a phylogenetic tree using the gene sequences obtained by NGS. Phylogenetic analysis revealed that MHC class I alleles were shared among different species of Scincidae with trans-species polymorphism, and did not exhibit specific genealogical inheritance. These results have important implications for understanding polymorphism interspecies diversity in the MHC genes of Scincidae, and the evolution of the MHC more broadly.

截至2023年1月,中国共记录312种蛇类,是世界上蛇类多样性最丰富的国家之一。物种特征决定其在环境中的生存能力,在进化生物学、生态学和保护生物学研究中具有重要作用。但是,目前还没有关于我国蛇类形态学、生活史和生态学等特征的完整数据库。本文通过系统查阅已出版的蛇类专业书籍、已发表的文献和爬行动物数据库,共收集整理了中国现有312种蛇类的41个特征数据。这些特征包括以下3个方面:形态特征(包括鳞片、牙齿等25个特征)、生活史特征(包括体长、食性、捕食方式、繁殖方式、活动时间、有无毒性等11个特征)和生态学特征(包括是否中国/岛屿特有种、成体生境、地理分布范围和海拔分布等5个特征)。在收集的41个特征中,除颏鳞、吻鳞和地理分布范围数据完整外(100%),其余特征数据都有不同程度的缺失(完整度为7.72%–99.70%)。本数据集是目前中国最新和最完整的蛇类特征数据集,可为我国蛇类的生态学、生物地理学和保护生物学等方面的研究提供基础数据支持。

通过采用科学本质（NOS）问卷对某地方高校生物、化学、物理专业1~4年级的507位本科师范生进行调查,以了解理科师范生在科学世界观、科学探究活动和科学事业等NOS的3个维度上的表现,以及科学本质观（UNOS）的现状,并分析专业、年级和性别等因素的影响。结果显示：理科师范生UNOS的总体水平略偏向于现代UNOS,但仍处于较低层次;生物专业的UNOS水平高于物理和化学专业;女生的UNOS水平好于男生;理科师范生的UNOS水平随着年级的升高而降低。据此,拟定出一系列可改善理科师范生UNOS的可行性建议。
