We incubated eggs of five Phrynocephalus species (P.albolineatus,P.axillaries,P.grumgrzimailoi,P.helioscopus and P.przewalskii) at three constant temperatures (24,28 and 32 °C) to examine differences
沙蜥属蜥蜴是青藏高原中较为典型且广泛分布的爬行动物,被认为是研究青藏高原爬行动物适应特征及其机制的好材料。本实验中我们选用世界上垂直分布最高的蜥蜴——红尾沙蜥以及低海拔分布的荒漠沙蜥作为研究对象,从种间角度比较分析了这两种沙蜥的形态特征、体温选择、线粒体呼吸速率,质子漏、部分代谢酶活性、氧自由基生成速率和代谢相关基因表达等多个方面,多学科交叉研究了红尾沙蜥对高原低温低氧环境的代谢适应特征,尝试发现
林蛙油是林蛙雌蛙的输卵管,其主要有效成分为蛙醇。近些年来,人们对于食品安全的重视程度越来越高,对于林蛙油内是否含有对人身体有害的物质也越来越重视。其中重金属进入人体要经过较长时间的积累才会显示出毒性,其往往不易被早期察觉,从而更加重了其危害性。
The histological structures and the morphological changes of oocytes and oviduct in the Chinese alligator were studied with light and transmission electron microscopy.
Kinship and density potentially affect important ecological processes such as competition,predation,growth and development,cannibalism,habitat selection and mate choice.
Phylogenetic relationships among 23 living species of order Crocodylia were reconstructed using DNA sequence data of nuclear and mitochondrial gene.
中国大鲵是我国特有的濒危两栖动物。由于具有较高的进化独特性,其在生物多样性保护中的地位非常重要。青海省是中国大鲵分布海拔最高的地区。由于该地区与中国大鲵其它分布地的隔离和环境差异,青海种群很可能具有独特的遗传组分,在分类学和物种保护方面具有重要的研究意义。

Sexual dimorphism in limb muscles is widespread among anurans,with males having stronger limbs than females.This phenomenon has been interpreted in the context of intrasexual selection: 1) the robust
两栖类由于其独特的生理特性,对气候环境变化,尤其是温度和水分的变化十分敏感。因此在环境变化时,其生存状况也容易受到影响。高原林蛙为分布在青藏高原东缘及周边地区,这一区域由于人类活动等原因,环境不断恶化,生物多样性保护面临巨大挑战。
