The Midgut Bacterial Flora of Laboratory-Reared Hard Ticks,Haemaphysalis longicornis,Hyalomma asiaticum,and Rhipicephalus haemaphysaloides

Ixodid ticks play an important role in the transmission of a variety of zoonoses of viral, bacterial and protozoan origin, and they also harbor a wealth of microorganisms. To gain more detailed insights into the potential interactions between bacterial flora and tick-borne pathogens, we investigated the midgut bacterial flora of laboratory-reared Haemaphysalis longicornis, Hyalomma asiaticum and Rhipicephalus haemaphysaloides. Based on morphological, biochemical, and 16 S rDNA sequencing results, we identified 15 species belonging to 12 genera in the midgut of the three ticks. The bacterial communities were similar to those found in other studies of hematophagous arthropods. Kocuria sp. was the most frequently isolated species and its 16 S rDNA gene sequence was very similar to Kocuria koreensis P31 T. To our knowledge, this is the first report of the bacterial flora of tick midguts and the results show that there were many different bacterial species in each tick species. Among the most common genera, there may have been a novel species in the genus Kocuria. The results might be the first step for looking for different aspects of the pathogen and tick interaction.

The Characteristics of Plant Communities Along East Eurasian Steppe Transect

The East Eurasian Steppe Transect （EEST） is the ifrst international transect across regions of middle and high latitudes in the eastern Eurasian steppe. The EEST is an ideal platform for researching the response of Eurasian temperate steppe to global change, because of its integrated gradients of temperature and human activities on a large-scale. In this study, basic characteristics of plant communities along the EEST across a latitudinal gradient was analyzed. According to the survey of 58 sampling sites, there are 140 species belonging to 34 families and 94 genera. Of particular note was the ifnding of Astragalus dalaiensis which has disappeared in the grasslands of China. On the whole, Gramineae plants are dominant with Liliaceae plants in the communities signiifcantly decreasing along the latitudinal gradient from south to north. The Shannon-Wiener index and biomass of communities all decreased along the latitudinal gradient with signiifcant negative linear regressions. The SDR2 （summed dominance ratio based on two factors） of dominant plants in the upper layers of communities, such as Stipa and Leymus chinensis, decreased along the latitudinal gradient from south to north. Especially, the SDR2 of L. chinensis decreased signiifcantly. The SDR2 of Cleistogenes squarrosa, Agropyron cristatum in the lower layers of communities and the indicator species for degradation were not affected. Potentilla acaulis was found mainly in the southern and northern areas. Stellera chamaejasme was found just in a few sites in the southern area of the EEST. In communities of Stipa grandis and Stipa krylovii, annual and biennial species are dominant. The ratio of annual and biennial species in the community is signiifcantly related to the latitudinal gradient. Perennial herbaceous plants and shrubs were not affected. According to the principal component analysis （PCA）, with the data from 58＆#215;140 dimensions, the ifrst and second components had the lowest proportion, thus indicating that the species compositions and community structures are homogeneous along the EEST. There is a certain degree of spatial differentiation along the EEST due to degradation’s differences resulting from the different land uses.

Abstract：

The species composition and diversity of plants on the Haishi Park limestone shrubland without anthropogenic disturbance for 20 years were studied based on data from 25 5 m×5 m plots. Important value index, richness index, species diversity index and evenness index were used to analyze the species composition and diversity of plants in the region and a comparison was made between the results of the study with the Cupressus funebris forest in Yunyang and the Sarcandra glabra communities in the Jinyun Mountains. A total of 78 species of vascular plants were found in the 625 m~2 plots. Richness index was in the order of shrub layer ＞ herb layer ＞ liana layer; species diversity index in the order of shrub layer ＞herb layer ≥ liana layer and evenness index in the order of liana layer ＞ shrub layer ＞ herb layer. Species diversity index in Haishi. Park was higher than that in C. funebris forest in Yunyang and S. glabra communities in the Jinyun Mountains.     

树冠圆满度对树木生长的影响及作用研究

树冠是树木的重要组成部分,其数量指标———树冠圆满度不仅客观地反映了树木占有生长空间的状况及竞争能力,而且对树木的生长过程和树木的形状都有着非常重要的影响。研究结果表明:在树木直径、树高较小(或年龄小)时,其树干材积也较小,而树冠圆满度较大,随着直径、树高的增加,其树干材积随之增加,但树冠圆满度逐渐变小。所以,树冠圆满度与直径、树高及树干材积之间存在着紧密的相关关系,其相关指数(R)基本上在0 80以上,而形数与树冠圆满度之间呈正相关。     

猪场空气细菌数量与猪高热综合征的相关性研究

自2001年入夏以来,浙江、上海等许多地区的猪群中流行以持续高热、气喘、皮肤发红为主要特征的猪"高热综合征",给养猪业带来了巨大的损失.但到目前为止,其主要病原依然未被确定.为了研究空气中细菌含量与该病的发生和严重程度之间的关系,我们对浙江省几个不同规模、不同发病情况的猪场的空气细菌含量进行了测试.结果发现:该病的发生及严重程度与猪舍内空气的细菌含量存在着明显的正相关性.

从经济学的视野看合同法的功能

从经济学角度而言,完备的合同必须具备四方面条件:完全竞争的市场;完全的理性;无外部负效应;零交易成本。但这些条件均不具有现实性。合同法的功能就是纠正合同的非完备性,使之趋于完备。在此分析基础上,对我国《合同法》的立法目的进行了审视。     

论从犯原因力的判断

从犯的原因力是指成立从犯所必需的因行为人的行为与其他人的犯罪行为之间产生的内在的必然联系。从犯是否成立，要经过一般性判断、具体性判断和排除性判断三个环节。一般性判断主要考虑是否具有成立从犯所要求的主观要件和客观要件，具体性判断涉及事前判断与事后判断、主观判断和客观判断、应然判断与实然判断，排除性判断主要考虑刑法分则的特殊规定和刑法总则中的但书。

关于西部大开发路径抉择的探讨 ——兼论西部的人口城市化

西部地区大开发是东部地区产业梯度转移的需要:在经历了改革开放20余年的高速发展之后,东部地区的劳动力成本日渐提高,其劳动力密集型产业日渐失去比较优势,东部的这些产业急需向中西部地区转移;西部大开发还是启动内需政策的需要:中央投资于西部的基础设施所带来的牵引投资效应将是巨大的;西部大开发更是可持续发展的需要:只有使西部走出“发展中的陷阱”,才能使西部的生态环境进入良性循环,只有进行西部大开发,才能使西部地区的社会经济“软环境”得到根本改善.……
