2006年5~9月,采用样带法对内蒙古白银库伦遗鸥自然保护区的两栖爬行动物进行了调查,共记录到两栖爬行动物12种,其中两栖类1目3科4种,爬行类2目4科8种.区系组成以古北界种类占明显优势.花背蟾蜍Bufo raddei和丽斑麻蜥Eremias argus分别为两栖类和爬行类的优势种.物种组成与附近的锡林郭勒自然保护区、赛罕乌拉自然保护区有较高的相似性.根据保护区的现状,提出了对两栖爬行动物的保护建议. 相似文献

由胡淑琴主编的《西藏两栖爬行动物》(1987年出版)汇总了1973年以来西藏两栖爬行动物考察的成果。全书记载了44种两栖类,54种爬行类,包括著者等先后发表的 11个两栖类新种,3个爬行类新种。过去对西藏两栖爬行类调查贫乏,如两栖类原有记录只有9种,故本书所记载的,除新种外,绝大多数是新纪录。本书以88%的篇幅分种记述形态,生活习性和分布,提供了较完整的资料,在区系方面的讨论,颇具特色。可以说,本书是半个多世纪以来,对本区两栖爬行动物分类和区系的第一次系统整理。它的出版,值得庆贺。 相似文献

为深入了解武陵山西部(贵州省、重庆境内)两栖爬行类的资源分布和物种多样性特征,于2014年8月及2015年4—5月对武陵山西部贵州省、重庆市境内的国家级自然保护区和森林公园的两栖爬行动物资源进行了实地调查。本次调查共采获两栖类2目8科24属43种,爬行类2目12科37属56种,其中我国特有种29种,列入中国濒危动物红皮书的22种。此外,经查阅资料对调查区域内两栖爬行动物名录进行了补充完善。结果表明,调查区域内物种大多为东洋界物种和广布种,仅有中国林蛙Rana chensinensis为古北界物种。G-F物种多样性指数分析发现,该区域内两栖爬行类物种多样性整体较高,且爬行类的指数均高于两栖类。与以往研究成果对比,当地两栖爬行类动物多样性形势相对稳定,但由于当地经济发展迅速,为维持生态系统稳定和经济可持续发展,应进一步加强栖息地保护。 相似文献

Madagascar has become a model region for testing hypotheses of species diversification and biogeography, and many studies have focused on its diverse and highly endemic herpetofauna. Here we combine species distribution models of a near-complete set of species of reptiles and amphibians known from the island with body size data and a tabulation of herpetofaunal communities from field surveys, compiled up to 2008. Though taxonomic revisions and novel distributional records arose since compilation, we are confident that the data are appropriate for inferring and comparing biogeographic patterns among these groups of organisms. We observed species richness of both amphibians and reptiles was highest in the humid rainforest biome of eastern Madagascar, but reptiles also show areas of high richness in the dry and subarid western biomes. In several amphibian subclades, especially within the Mantellidae, species richness peaks in the central eastern geographic regions while in reptiles different subclades differ distinctly in their richness centers. A high proportion of clades and subclades of both amphibians and reptiles have a peak of local endemism in the topographically and bioclimatically diverse northern geographic regions. This northern area is roughly delimited by a diagonal spanning from 15.5°S on the east coast to ca. 15.0°S on the west coast. Amphibian diversity is highest at altitudes between 800–1200 m above sea-level whereas reptiles have their highest richness at low elevations, probably reflecting the comparatively large number of species specialized to the extended low-elevation areas in the dry and subarid biomes. We found that the range sizes of both amphibians and reptiles strongly correlated with body size, and differences between the two groups are explained by the larger body sizes of reptiles. However, snakes have larger range sizes than lizards which cannot be readily explained by their larger body sizes alone. Range filling, i.e., the amount of suitable habitat occupied by a species, is less expressed in amphibians than in reptiles, possibly reflecting their lower dispersal capacity. Taxonomic composition of communities assessed by field surveys is largely explained by bioclimatic regions, with communities from the dry and especially subarid biomes distinctly differing from humid and subhumid biomes. 相似文献

湖北神农架国家级自然保护区两栖爬行动物物种多样性 总被引:2,自引:1,他引:1
对神农架自然保护区两栖爬行动物进行调查,整理了神农架自然保护区两栖爬行动物名录共71种,新发现湖北省新分布种6种,其中腾格里蛙Rana tenggerensis Zhao,Macey et Papenfuss、宁陕小头蛇 Oligodon ningshaanensis Yuan离原分布区较远,神农架新分布种3种,神农架两栖爬行动物的区系特征以东洋界(74.69%)为主,广布种(18.31%)、古北界(7%)种类次之,体现了南北混杂的特点.随着海拔的升高,两栖爬行动物生物多样性总体呈下降趋势,400~1600 m两栖爬行动物生物多样性最高,随海拔下降的趋势不明显,1900 m以上多样性急剧下降. 相似文献
