Two new species of Oxycera (Diptera, Stratiomyidae) from Ningxia, China

Two new speices, Oxycera rozkosnyisp. n. and Oxycera ningxiaensissp. n., are described from Liupanshan Nature Reserve, Ningxia Hui Autonomous Region, Northwest China. All essential diagnostic characters are figured and possible relationships of both taxa are briefly discussed, and a new key to species of Oxycera from China. The type specimens are deposited in the Institute of Entomology, Guizhou University, Guiyang (GUGC).     

A comparative analysis of the <Emphasis Type="Italic">hsp70</Emphasis> gene system in two species of the family stratiomyidae (Diptera)

The structure of the hsp70 gene cluster was investigated for two species of the family Stratiomyidae (Diptera), Stratiomys singularior and Oxycera pardalina. Their larvae inhabit nearshore-aquatic biotopes with contrasting temperature regimes, composition and concentration of salts. It was shown that the S. singularior hsp70 gene cluster contains five copies and has a compact structural organization (the interval length did not exceed 5 kb). The O. pardalina hsp70 gene cluster contains four copies located at larger distances in comparison with the S. singularior and also includes the hsp68 gene. High variability in the structure of the S. singularior hsp70 gene cluster was detected.     

Larvae of related Diptera species from thermally contrasting habitats exhibit continuous up-regulation of heat shock proteins and high thermotolerance

A population of Stratiomys japonica, a species belonging to the family Stratiomyidae (Diptera), common name ‘soldier flies’, occurs in a hot volcanic spring, which is apparently among the most inhospitable environments for animals because of chemical and thermal conditions. Larvae of this species, which naturally often experience temperatures more than 40 °C, have constitutively high concentrations of the normally inducible heat-shock protein Hsp70, but very low level of corresponding mRNA. Larvae of three other species of the same family, Stratiomys singularior, Nemotelus bipunctatus and Oxycera pardalina, are confined to different type semi-aquatic habitats with contrasting thermal regime. However, all of them shared the same pattern of Hsp70 expression. Interestingly, heat-shock treatment of S. japonica larvae activates heat-shock factor and significantly induces Hsp70 synthesis, whereas larvae of O. pardalina, a species from constant cold environment, produce significantly less Hsp70 in response to heat shock. Adults of the four species also exhibit lower, but detectable levels of Hsp70 without heat shock. Larvae of all species studied have very high tolerance to temperature stress in comparison with other Diptera species investigated, probably representing an inherent adaptive feature of all Stratiomyidae enabling successful colonization of highly variable and extreme habitats.     

Spring macrobenthos communities of the Moscow province

Macrozoobenthos communities are described based on material from 70 springs and spring brooks of the Moscow province. The communities include 587 taxa of various origin: 27 rheophiles, 11 crenobionts, 10 ubiquists of small water bodies, and 3 limnophiles. Rheophile species predominate in diversity (52%) and total abundance (41.5%). Crenobionts include Beraea pullata, B. maura, Crunoecia irrorata, Apatania zonella, Parachiona picicornis, Potamophylax nigrocornis, Oxycera pseudoamoena, O. rara, O. pardalina, Pedicia rivosa, Thaumalea testacea; six of these are recorded in the region for the first time. Four types of spring communities are recognised in the region according to the Braun-Blanquet method: with predominant Rhyacophilafasciata and Baetis rhodani (macrorheocrenes), Potamophylax nigroicornis (microrheocrenes), Nemurella pictetii (limnocrenes), and Parachiona picicornis (helocrenes). Three of them are confined to water bodies of different size and flow velocity; one (N. pictetii) is linked to weakly flowing silted wated bodies. Change of spring communities is often observed also downstream due to the distance from the opening of the spring. The structure of rheocrene communities is most similar to that of brooks, that are significantly larger than the rheocrenes. Limnocrene and helocrene communities have no counterparts among communities of other types of water bodies. Some of the specific traits of spring communities fit the island theory and can be explained by it. Comparison of the studied communities with those of springs of Sweden and England reveals wide variance of the general faunistic composition of the communities with a rather stable assortmeont of troglobiot species.     

A Study on the Genus Astilbe Buch.-Ham. ex D. Don from China

The Astilbe Buch.-Ham. ex D. Don was founded in 1912. There are now 18 species throughout the world. USSR, Thailand, Indonesia, Bhutan, Nepal d Kashanmir each has only 1 species; Korea, Philippines and USA each has 2; India 3; Japan 6; and China 7 (including 3 endemics and 1 new variety). And northeast China, north China and northwest China each has 2; central China and southwest China each 4; eastern China 5. Thus the distribution centre of this genus seems to be in the region covering Japan and eastern, central, and southwest China. This genus is divided into two sections: Sect. Simplicifoliae Engl. and Sect. Astilbe. Sect. Simplicifoliae may be considered as the primitive one because it has 5 ordinary petals. This section consists of about 10 species: 5 in China (east China 4; southwest China 3; central China, north China and northeast China each 2; Northwest China 1), 5 in Japan, 2 in Korea, 1 in Philippines and India each. According to the distribution of this section, the author suggests that the centre of origin of this genus be in the forested parts from Japonthrough east China to southwest China.     

中国扁叶甲属地理分布格局研究(叶甲科,叶甲亚科)

本文运用GIS技术研究扁叶甲属Gastrolina在中国的地理分布格局。以采集地的行政单元转换地理坐标与动物地理区划图叠加后产生叶甲的地理分布图。结果显示此属主要分布在华中区、华北区、华南区、西南区、东北区。根据地理分布图及有关分析,认为华中区中部、华北区西北部是该属的丰富度中心和分布中心,华中区中部为中国扁叶甲多样性中心和分化中心。     

中国苔藓植物的地理分区及分布类型

在对中国苔藓植物相关研究资料进行总结归纳的基础上,对中国苔藓植物的分区进行了重新划分,将最初的7个分区划分为10个分区,从华中区中分出华东区,由华北区中分出华西区,并将青藏区及云贵区内的云南西北部、四川西南部和西藏东南部组成单独的横断山区。就中国苔藓植物的分布类型及可能的分布路线也作了讨论,指出中国苔藓植物的分布路线有3条,一条是从喜马拉雅地区经滇西北、川西沿长江流域到中国的东南部;一条位于喜马拉雅、横断山区和台湾之间;第三条则从喜马拉雅地区通过秦岭直至长白山区。
