陕西清涧县达乌尔黄鼠调查与防治研究初报

本文选用几种简便易行的灭鼠或捕鼠方法，对清涧县达乌尔黄鼠对农田危害情况进行了调查，发现不同季节危害程度不同，川道地区较梁峁、沟壑地区严重，并且对该县达乌尔黄鼠久治而效果不显的原因作了理论性探讨，并提出了应采取的防治措施。     

宁复阿拉善黄鼠酯酶同工酶的研究

运用垂直板薄层聚丙烯酰胺凝胶电泳技术对我国宁夏海原县南华山地区阿拉善黄鼠(Spermophilus dauricus alaschnicus)的11种组织进行了酯酶同工酶研究。计算了各组织间酶谱相似系数,并对11种组织根据酶谱相异性进行了极点排序(polar ordination)。结果表明:阿拉善黄鼠酯酶同工酶谱及活性在不同组织中存在着明显差异。     

脑室注射6-羟多巴胺对达乌尔黄鼠体温及体温调节能力的影响

观察了脑室注射6-OHDA对达乌尔黄鼠体温及体温调节能力的影响。结果表明:(1)脑室注射200μg 6-OHDA产生一个短暂的急性低体温效应,在室温环境中体温下降幅度为5℃左右,在5℃寒冷环境中体温下降7℃左右。脑室注射第二个剂量6-OHDA所引起的低体温效应比第一次明显减弱;中枢投入α-受体阻滞剂可以取消此低体温效应。(2)脑室注射6-OHDA对体温调节能力仅有暂时性影响,注药20小时后,体温调节能力即可恢复,动物在寒冷环境中和正常动物一样能够维持恒定的体温。这些观察结果为应用6-OHDA于冬眠实验工作提供了一个基本的参考依据。     

Carboniferous adakites and Nb-enriched arc basaltic rocks association in the Alataw Mountains, north Xinjiang： interactions between slab melt and mantle peridotite and implications for crustal growth

Adakites and Nb-enriched arc basaltic rocks (NEABs) in arc setting, which are closely correlated in petrogenesis, have recently been widely followed with interest[1—9]. In general, adakite is derived from partial melting of subducting oceanic crust[1]. When adakitic magma (slab melt) passes through the mantle wedge, the interactions between slab melt and mantle peridotite will occur: slab melt is contaminated by peridotite, meanwhile peridotite is metasomated by slab melt. The NEABs are d…     

阿拉善地区降水同位素特征与水汽来源

基于2013—2015年阿拉善高原阿右旗的降水氢氧稳定同位素组成数据,分析阿拉善高原降水δD和δ~(18)O的特征与变化规律,揭示当地的水汽来源与迁移路径。结果表明:(a)阿拉善高原降水δD和δ~(18)O的变化呈现明显的季节特征,即夏季偏高,冬季偏低。(b)主要气象参数(降水量、气温、大气湿度和风速)中,气温是控制阿拉善高原降水δD和δ~(18)O的主导因素;通过与周边区域的比较,阿拉善高原当地大气降水线的斜率和截距较低,这是由阿拉善高原降水受到非平衡蒸发作用强烈所致;(c)HYSPLIT气团轨迹模型模拟和降水同位素分析揭示了阿拉善高原阿右旗降水主要来自西风和极低气团。     

用RT-PCR方法检测达乌尔黄鼠(Spermophilus dauricus)白色脂肪组织中瘦素的基因表达

达乌尔黄鼠（Spermophilus dauricus）作为研究冬眠的优良模式动物,已经在医学、生理学以及生态学领域得到广泛的应用。但是目前尚未见使用分子生物学手段对达乌尔黄鼠（Spermophilus dauricus）进行冬眠机理方面的研究。瘦素在调节摄食、能量平衡和入眠方面都有非常重要的作用。尝试使用RT-PCR这一分子生物学技术对达乌尔黄鼠的瘦素和β-actin进行特异性扩增,并对其进行克隆测序,得到了达乌尔黄鼠的瘦素和β-actin基因片段的序列,为研究达乌尔黄鼠冬眠的分子机制提供基础数据。同时总结了用RT-PCR方法检测未知基因序列物种有关基因表达时需要注意的一些问题。

High lake levels on Alxa Plateau during the Late Quaternary

Field investigations including lake shoreline measurement and ¹⁴C chronology have been carried out on the Alxa Plateau to better understand the formation and evolution of the high lake levels in northwest China during the late Pleistocene. Comprehensive field investigations show that there are at least ten shorelines at different elevations at Juyan Lake, at least four on the northwest side of the Jilantai Salt Lake, and nine shorelines and one terrace on the northeast margin of Zhuye Lake. Stratigraphic correlations and chronological evidence indicate that the paleo-lakes have the highest lake levels in Marine Isotope Stage (MIS) 3. Though the optically stimulated luminescence (OSL) results which have been reported by some scholars do not support this view, the fact that the paleo-lakes have the highest lake levels in MIS 3 can not be denied. Differences between OSL and ¹⁴C results from this work might indicate that high lake levels existed on the Alxa Plateau during two different periods. It also suggests that the high lake levels may exist in both MIS 5 and early MIS 3. This paper also provides the basic hydrological information for further water resources research in this arid region.
