On the population dynamics of Eudiaptomus gracilis Sars and Heterocope borealis Fischer in the Bodensee-Obersee. Part B. Eudiaptomus gracilis Sars. [Translation from: Trudy Instituta Biologii Vnutrennykh Vodnany 12(15) 170-174, 1966.]

Experimental research was conducted to study the development of eggs of Eudiaptomus gracilis Sars. The egg production was studied as well as the population dynamics. Factors like losses in the lake and through the effluent Rhine at Konstanz were considered.

On the ecology of species belonging to the genus Mesocyclops Sars (Crustacea, Copepoda) dwelling in the water-bodies of the Urals and Pri-Ural territory. [Translation from: Zoologicheskie Zhurnal 44(1) 127-130, 1965. ]

In the waterbodies of central Russia, the Urals and western Siberia four species of Crustacea, related to the genus Mesocyclops, are widely distributed: M. (s.str.) leuckarti (Claus), M. (Thermocyclops) oithonoides Sars, [M.](Th.) crassus (Fisch.) and M. (Th.) dybowskii (Lande). Numbers and biomass of Mesocyclops oithonoides in the pelagic water of various water-bodies of the Urals are presented and observations on the above mentioned species are discussed.

Feeding of Gammarus lacustris Sars under different conditions of habitation [Translation from: [Trophic relations of freshwater invertebrates.] (ed. G. G. Vinberg) pp.94-98. Leningrad, Zool.Inst.AN SSSR, 1980]

The amphipod Gammarus lacustris, a regular representative of lacustrine communities, often plays a significant role in the transformation of matter and energy. The object of the present work was to clarify the quantitative side of the feeding of the amphipod under different conditions of habitation. Experimental works on determination of the rate of consumption of food and its dependence on body-weight were carried out in the summer periods 1975-1978 on three water-bodies of the Krasnoyarsk region, of different conditions of habitation for the amphipods.

SARS 及其它冠状病毒基因组组织结构和序列的初步比较分析

:严重急性呼吸综合症(Severe acute respiratory sydrome , SARS) 是一种全新的传染性疾病,它可能主 要是由冠状病毒的一个变种引起的. 本文比较SARS 及其它冠状病毒基因组组织结构和序列变异的情况,初步 的结果表明: ①尽管SARS 病毒与冠状病毒属的另外6 种病毒基因组序列上有较大的差异,但是它们具有较相 似的基因组组织结构; ②SARS 病毒与牛冠状病毒、鼠肝炎病毒具有较近的系统发育关系; ③虽然SARS 病毒扩 散的时间极短,但来自不同地区SARS 病毒的DNA 序列却存在一些突变,且这些突变又大多是改变氨基酸序 列的非同义突变.

冠状病毒

冠状病毒(coronavirus)是一种常见的单链、非片段化、线性、正链RNA包膜病毒，能感染脊椎动物而引起，特别 是呼吸系统疾病。此病毒可分三大类，感染不同动物，其遗传物质RNA表现出一种特殊的、有趣的、目前并不为人们 完全所知的策略完成其自身繁殖。最近，科学家发现“非典型肺炎”的病原体为一种新型的冠状病毒，表现出其特别 的基因组结构，有别于已知的典型冠状病毒，相关研究正在进行中。

角突泥介虫(Ilyocypris angulata Sars)(介形亚纲)雄体的发现

本文报道了角突泥介虫(Ilyocypris angulata Sars)雄体的发现。对此雄体进行了详细的描述,论述了泥介虫属的生活方式,并讨论了介形类有三种生殖方式。

瘦尾细额溞Oxyurella tenuicaudis(Sars,1862)的若干生物学特征

瘦尾细额溞是一种出现数量极其稀少的枝角类。关于它的生物学特征尚未见诸文献。本文测量了一次采自云南永胜一池塘的本种300个两性个体的体长和怀卵量,就其幼体与成体的数量、体长与怀卵量、雄性以及性比等问题探讨了种群的生物学状况。 详细观察比较了这个种的重要分类特征——雌体后腹部,并描述了变异范围。对卵鞍和雄体也作了描述。

SARS起源于污染对病毒进化的加速诱导

针对当前广为流传的SARS病毒“太空起源说”和“野生动物来源说”两种理论 ,本文根据污染进化生态学原理和SARS病毒发病传染特征 ,以有关实验结果为科学依据 ,阐述了SARS病毒的起源问题 ,指出 :我国当前环境日益严重的复合污染为SARS致病病毒的产生提供了适宜的外部生态条件和物质基础 ,SARS致病病毒可能起源于多个病毒的基因重组或融合 ,更可能是一种来自于感冒病毒进化而形成的超级感冒病毒 .可以预料 ,这一推断将为彻底解决SARS的病源提供有价值的理论指导
