Background: Air temperature affects absorptive root traits, which are closely related to species ***, it is still unclear how air temperature regulates species distribution through changes in absorptive root traits. Seven functional traits of the absorptive roots of 240 individuals of 52 species, soil properties and air temperature were measured along an elevational gradient on Mt. Fanjingshan, Tongren City, Guizhou, and then the direct and indirect effects of these controls on species distribution were ***: Absorptive roots adapted to air temperature with two strategies. The first strategy was positively associated with the specific root area(SRA) and specific root length(SRL) and was negatively associated with the root tissue density(RTD), representing the classic root economics spectrum(RES). The second strategy was represented by the trade-off between root diameter, mycorrhizal fungi colonization(MF) and SRL, representing the collaboration gradient with “do it yourself” resource uptake ranging from “outsourcing” to mycorrhizal resource uptake. Air temperature regulated species distribution in six ways: directly reducing species importance value;indirectly increasing the species importance value by reducing soil nitrogen content or increasing soil pH by reducing soil moisture inducing absorptive roots to change from “do it yourself” resource absorption to “outsourcing” resource absorption;indirectly decreasing the species importance value by decreasing soil moisture to change from“outsourcing”resource absorption to “do it yourself” resource absorption;indirectly increasing the species importance value with increasing soil pH by reducing soil moisture resulting in absorptive root traits turning into nutrient foraging traits;and indirectly decreasing the species importance value by promoting absorptive root traits to nutrient conservation ***: Absorptive root traits play a crucial role in the regulation of species distri

我国服务贸易统计制度自2008年正式实施以来,共经历了5次修订。"历经数次修订的服务贸易统计制度有无进一步改进的空间?"这是一个值得探讨的问题。文章从服务贸易统计制度设计质量视角出发,以DQAF作为评价框架,采用ROSC-DM方法,将我国服务贸易统计制度内容与《服务贸易统计手册2010》《MSITS2010编制者指南》中的一般原则和要求进行了比较。比较结果显示:我国服务贸易统计制度设计较简单,内容不能涵盖DQAF框架中的所有质量维度和大多数评估要素。尤其在质量的前提条件、准确性和可靠性、适用性和可获得性等维度上,我国服务贸易统计制度设计与《服务贸易统计手册2010》及其编制者指南的基本要求存在较大差距。文章认为我国服务贸易统计制度设计质量水平总体不高,仍有较大的改进空间。

在室内分别测定了甜菜夜蛾的卵、雌蛾和雄蛾分别携带甜菜夜蛾核型多角体病毒(SeNPV)对其卵孵化率、幼虫存活率及单雌产卵量的影响。结果表明:甜菜夜蛾卵块携带SeNPV后,卵孵化率和幼虫存活率均显著下降。雌、雄蛾分别携带病毒再交尾后,对单雌产卵量、卵孵化率和幼虫的存活率也有显著影响,并且不同带毒量处理间存在显著差异,表现为带毒量越高,单雌产卵量越少、卵孵化率和幼虫存活率越低。同等带毒处理条件下,卵、雌蛾和雄蛾带毒3种处理方式对甜菜夜蛾种群数量的影响没有显著差异。说明SeNPV能通过甜菜夜蛾的卵、雌蛾和雄蛾3种虫态进行垂直传播,可以明显抑制甜菜夜蛾种群数量的增长,为昆虫性诱剂和病毒集成技术在田间的应用提供了理论依据。

目的探讨Survivin在涎腺良性多形性腺瘤(PA)、交界性多形性腺瘤(RPA)、恶性多形性腺瘤(MPA)中的表达及其与肿瘤增殖活性的相关性。方法应用免疫组织化学方法及原位杂交技术检测14例涎腺PA、9例RPA、11例MPA以及9例癌旁腺组织中Survivin的表达。结果Survivin mRNA在涎腺PA、RPA、MPA中的表达与其蛋白表达相比均无显著性差异,而在癌旁腺体中的表达存在显著性差异(P<0.05);在涎腺PA中Survivin mRNA及其蛋白的表达均明显低于RPA、MPA及癌旁组织(P<0.01),而RPA与MPA中的表达无显著性差异;在MPA中高分化者与中低分化者的表达均有显著性差异(P<0.05)。结论Survivin基因的转录和扩增可能参与多形性腺瘤的发生、发展及恶变进程,并且在肿瘤发生的不同阶段有不同表达,有望成为涎腺肿瘤诊断和治疗的新靶点。
