We present preliminary taxonomic information necessary for a generic key to North American Encyrtidae. Fourteen new generic synonymies, one new specific synonymy, 67 new combinations and three replacement names are proposed. Twenty one genera and 18 species are described as new. 相似文献

With the interest in studying science as practice came an interest in the material artefacts and things that form part of scientific activities in the laboratory, the field, the classroom, or the political arena. This shift in interest in connection with new modes of knowledge production raises new questions regarding the “archive” of science: what should be preserved and where to make it possible to reconstruct scientific practices in the desired detail? While digital media may be able to bridge some of the traditional divisions between the collection of scientific artefacts in museums and the written archival depositories, the move to performing science in silico produces new challenges in respect to establishing the material archives of current science. The paper will discuss these and related questions with special reference to the archives of the contemporary life sciences. 相似文献

The genus Tetradinodula Zha gen. nov. (type species: T. bambusae Zha sp. nov.) is described from the Baiqing Nature Preserve, Tongzi County, Guizhou Province, China. Ecology and habits of the new species are discussed. Genera of Cladonotinae from China are reviewed and a revised key for identifying the genera of Chinese Cladonotinae is presented.

Fossil Cyclocypris diebeli Absolon, 1973 from Europe are redescribed, utilizing material with chitinous preservation of the appendages and carapace. These are compared with living C. diebeli from Kushiro Marsh, Hokkaido, Japan, representing the first living population of this species ever found. The fossil material is associated with strongly calcareous sediments, whereas the living material is found in weakly calcareous to acidic waters. Reasons for the different ecological requirements are discussed. Detailed study of soft parts of both living and fossil material using SEM is compared with other Cyclocypris species and it is shown that C. diebeli is more closely related to the North American Cyclocypris cruciata Furtos, 1935 than to any European congeneric species. Furthermore, the comparison with other Cyclocypris species with left>right valve overlap results in the conclusion that the subgenus Laevicypris Krsti?, 1995 is not a useful division of the genus. 相似文献

江苏省竹类植物的新记录和新种 总被引:3,自引:0,他引:3
<正>江苏省自然条件优越,竹种资源比较丰富,但在林业生产上除毛竹、刚竹、淡竹外,对其他竹种了解甚少。虽然几年前南京大学,南京林学院、江苏省植物研究所先后对江苏省的竹子分类做了不少工作,但均未系统全面的调查,遗漏较多。近年来,南京林学院和江苏省林业科学研究所受江苏省农林厅的委托,对全省竹种资源进行了一次全面的调查,野外工作历时两年,调查了28个市、县的野生,栽培、山区、平原以及庭园观赏竹种(但不包括南京林学院、南京菊花台公园以及中山植物园引入栽培的竹种)。经我们研究鉴定,江苏省的竹种共有10个属和55个种及种下分类单位。其中有些竹种是江苏省过去未曾记载报道过的,个别竹种甚至在国内也是初次被研究。为了生产单位和科研机关及早了解和掌握江苏省的竹种资源,现将这次调查所发现的新记录的竹种和新种以及分类上需要订正的竹种简要报道如下,以供参考。为了节省篇幅,凡国内文献已有形态描述的竹种,本文只列参考文献,不作形态记载。 相似文献

Quantitative relationships between vegetation and several pollen taxa in surface soil from North China 总被引:7,自引:1,他引:6
According to the vegetation investigation and pollen analysis of surface samples sampled along a precipitation gradient of
the Northeast China Transect (NECT), several pollen taxa, includingPinus, Betula, Quercus, Tilia, Acer, Ulmus, Artemisia, Chenopodiaceae, Gramineae and Cyperaceae, were chosen to make the regression and correlation analyses. The results indicated
that there exists a close relationship between vegetation and pollen taxa in surface samples. The regression parameters for
ten taxa in the forests in the eastern part of NECT were different from those in the steppes in the western part.Pinus, Betula, Artemisia and Chenopodiaceae, which have large slope and y-intercept terms, were over-representative taxa.Acer, Gramineae and Cyperaceae, which have small slope andy-intercept terms, were under-representative taxa.Quercus, Tilia andUlmus whose slope terms have negative correlation withy-intercept terms were equi-representative taxa. The pollen taxa with large slope or largey-intercept terms have small variability coefficients, implying that the slope andy-intercept terms for these pollen taxa are of high accuracy in the estimation of plant abundance from pollen frequencies. 相似文献

The phylogenetic relationship of Hexapoda has been debated for a long time, which will be resolved mainly depending on the settlement of monophyly, affinities and interrelationships among Protura, Collembola and Diplura. Mitochondrial 12sRNA gene about 355 bp fragments from one proturan species, two collembolan species, two dipluran species and one oribatid species were sequenced. The Kimura 2-parameter distances were calculated and a series of molecular phylogenetic trees were reconstructed by using the N-J method, from which the following points were drawn: (ⅰ) Protura and Collembola compose a monophyletic group representing absent-cerci; (ⅱ) Diplura is not a monophyletic group, in which Campodeoid with filiform cerci belongs to a clade and Japygoid with pincer cerci and Ectognatha compose another clade, that is, Insecta s. str. stemmed from Japygoid. So it would be suggested that the phylogenetic relationship of Hexapoda is [Parainsecta (Collembola + Protura) +Campodeoid +Insecta (Japygoid + Ectognatha)]. 相似文献
