米仓山攀蜥(Japaluramicangshanensis)是宋鸣涛(1987)依据1982年在陕西省宁强县青木川所采标本描述的种。目前仅知分布于陕西南部地区。作者1999年6~7月在甘肃省陇南地区进行野外考察,先后于6月10日~6月14日、7月9日~17日在文县刘家坪、康县阳坝和文县碧口采到鬣蜥科龙蜥属标本22号,经鉴定为米仓山攀蜥,为甘肃省新纪录。米仓山攀蜥与草绿攀蜥(JaplaluraflavicepsBarbourandDunn)相近似。区别是前者没有喉褶;上唇鳞7~8枚,下唇鳞8~9枚;尾长为头体长的两倍(个别超出两倍)。草绿攀… 相似文献

摄食对原尾蜥虎代谢率的影响 总被引:1,自引:0,他引:1
通过测定摄食后原尾蜥虎成体的耗氧量变化,研究摄食特殊热动力作用(SDA).蜥虎分为摄食黄粉虫幼虫实验组和禁食对照组,两组动物平均体重无显著差异.测定耗氧量前,将所有动物在30℃恒温室内禁食3天.用容积为300 ml的封闭式呼吸室测定两组蜥虎在30℃条件下连续3天的耗氧量,测定间隔时间为4~12 h.禁食组动物实验期间的耗氧量无显著的时间变异,实验组动物耗氧量的时间变异显著,这些结果表明摄食影响原尾蜥虎的代谢率.实验组动物摄食4 h后耗氧量已显著大于禁食组,摄食40 h后两组动物的耗氧量无显著差异.原尾蜥虎达到SDA峰值的平均时间约为20.0 h,SDA峰值耗氧量是禁食对照组动物耗氧量的1.5倍.原尾蜥虎单次摄食实验中的SDA具有进食后耗氧量迅速增加、达到峰值后下降至摄食前水平的典型模式. 相似文献

Hedruris hanleyae n. sp. (Nematoda: Hedruridae) from the stomach of Hemidactylus garnotii collected in 1989 on Atiu, Cook Islands is described and illustrated. Hedruris hanleyae n. sp. represents the 21st species to be assigned to the genus and is distinguished from other oriental species by the distribution pattern of caudal papillae of the male: 10 pairs posterior subventral papillae; 2 pairs precloacal and 8 pairs postcloacal. 相似文献

正淡灰豹鼩(Pantherina griselda)隶属于鼩形目(Soricomorpha)鼩鼱亚科(Soricinae)豹鼩属(Pantherina),其模式产地为中国甘肃省临潭县(Thomas,1912)。由于淡灰豹鼩整体形态与黑齿鼩鼱属(Blarinella)中的原甘肃川鼩(B.griselda)相似,且二者同域分布,曾被记录为黑齿鼩鼱属中的一个隐存种Blarinella sp.(Bannikova et al.,2017);He等 相似文献

We have observed the seropositive rate of Taenia solium cysticercosis in residents at Nabo Village, Tiandong County, Guangxi Zhuang Autonomous Region, China by enzyme linked immunosorbent assay. The village had been found to be a relatively high endemic area of porcine cysticercosis among roaming pigs. Of 202 persons examined four males aged 15, 25, 35 and 41 year-old exhibited absorbance (abs) at 0.18, 0.20, 0.35 and 0.55, respectively. In addition, two females whose ages were 35 and 39 years revealed specific antibody levels of abs 0.26 and 0.41 in their sera. Overall positive rate among the people was 2.97%. All of these persons agreed that they had ingested the pork infected with T. solium metacestode (TsM), while history of proglottid discharge was not noticed from all of them. Three males and one female complained of intermittent headache. Our findings reinforced not only that the prevalence of cysticercosis might be related with roaming pigs infected with TsM but also that behavioral and environmental practices in local community constituted risk factors for transmission of the infection. 相似文献

A new large species of gecko superficially resembling Hemidactylus maculatus Duméril & Bibron and its allied large Hemidactylus is described from Eastern Ghats. The new species, Hemidactylus kangerensis sp. nov. can be easily distinguished from members of the H. maculatus complex based on the number of femoral pores, i.e. 18–21 on each side, separated medially by 4 non-pored scales. A phylogenetic analysis based on partial sequence of mitochondrial gene cytochrome b shows that the gecko is a member of the “H. prashadi” clade and is sister to H. maculatus, from which it differs in an uncorrected pairwise sequence divergence of 10%. The discovery of a new large gecko from Eastern Ghats advocates the need for biodiversity assessment across the neglected Eastern Ghats. 相似文献
