蛛网和蛛体挥发物诱导的阴暗拟隙蛛（蜘蛛目：漏斗蛛科）种内选择偏好行为

化学通讯是蜘蛛类群普遍使用的种内和种间信息交流方式,极可能是蜘蛛进化过程中最初用来进行个体之间信息交流的途径。本研究利用双向选择系统,测试了阴暗拟隙蛛(Pireneitega luctuosa)对同种其他个体的蛛网和蛛体挥发物的选择行为,采用卡方检验的统计学方法、利用SPSS 19.0和Origin Pro 8等软件对所测蜘蛛的选择数据进行了分析。结果显示:①阴暗拟隙蛛雄蛛和雌蛛对来自同种异性的蛛网(P 0.001)和蛛体挥发物(P 0.05)均具有显著的趋向性,雌、雄蛛在异性蛛网或蛛体挥发物所在的选择盒表现更长时间的停留、探索、织网等行为;②雄蛛和雌蛛对幼蛛蛛体释放出来的挥发物均表现出显著的回避行为(P 0.05),倾向于远离具有幼蛛挥发物的选择盒;③幼蛛对同种幼蛛和雄蛛的蛛网(P 0.001)以及同种幼蛛的蛛体挥发物(P 0.05)均具有选择偏好性,说明幼蛛倾向于与同种个体接近。我们的研究表明,阴暗拟隙蛛雄蛛、雌蛛及幼蛛的蛛网和蛛体挥发物能诱导种内其他个体的趋向或回避行为,阴暗拟隙蛛幼蛛对同种幼蛛的选择偏好性可能是该种个体在同一地域聚集分布的主要原因。我们的研究从行为学角度证实,阴暗拟隙蛛的蛛网及体表均携带有能够标识其性别和龄期的相关信息化学物质。     

Influence of farming system on the floristic composition of paddy landscapes: a case study in a rural hilly zone in Zhejiang province,China

The effects of two contrasting farming systems on the floristic composition and vegetation structure that make up the Yatoda landscape were investigated. The experimental field was set up at Yatoda in a hilly district in Zhejiang province, China. Vegetation surveys were done in summer 2002 and 2003. Vegetation was divided into four types based on species composition: grassland formerly used for rice cultivation (G), rice paddy (P), ridge way (R), and levee slope (S). In P, R, and S plots, each vegetation type was subdivided according to the different farming systems. Under the traditional system, there were a number of species, and the diversity index values were greater than those under the conventional system. Blyxa echinosperma and Marsilea quadrifolia, which are threatened species in Japan, were seen in the paddy field under the traditional farming system.     

7个鹅观草居群的形态学和细胞遗传学研究

鹅观草广泛分布于我国各地及日本和朝鲜等地,具有丰富的遗传变异,种内变异类型丰富,一些居群间存在明显的生殖隔离。本研究利用人工杂交、形态学、繁育学及染色体组分析方法对来自四川雅安、四川宜宾新文、四川宜宾翠屏山、青海、新疆、浙江及山东的7个鹅观草居群进行了遗传分化研究。结果显示:(1)不同居群在株高、穗长、外稃长等表型性状存在差异,各居群间杂种F1表型性状普遍优于两亲本居群,但是颖宽个别性状劣于亲本。(2)各居群间杂种F1染色体配对水平总体较高,但也存在差异;二价体数目变异范围为19.77~20.91,单价体数目变异范围为0.18~2.46,还有低频率的三价体、四价体出现。(3)杂种F1的育性为78.9%~89.67%,自然结实率43.05%~77.98%,其中浙江与四川宜宾翠屏山居群的杂种F1的自然结实率最低(43.05%)。以上结果表明,7个鹅观草居群间存在一定程度的分化,且与各居群的地理分布呈正相关;四川宜宾与浙江居群之间存在一定的生殖隔离,遗传变异较大。     

Long-term changes of aphid vectors of Barley yellow dwarf viruses in north-eastern Italy (Friuli-Venezia Giulia)

Migrations of aphid vectors of Barley yellow dwarf viruses (BYDV) were monitored using a Rothamsted Insect Survey suction trap in Friuli-Venezia Giulia (north-eastern Italy). Catches from 1983 to 2002 were studied for trends, correlations of total catches of each year with those of previous years, correlations between the autumn and the spring + summer catches of the same year and between spring + summer catches of one year with catches of the previous autumn. Infectivity of autumn alates was studied using biological tests, and infectivity indexes were calculated for all vector species and for Rhopalosiphum padi alone. Colonisation of barley and proportion of infected plants were checked in a field close to the suction trap from 1992 to 2002 and related to trap catches. Catches were also correlated to acreage dedicated to cereal and fodder crops in the region. During the 20 years, 15 BYDV vector species were caught in the trap, but only five species were found consistently colonising barley plants during autumn. R. padi was the most numerous species in catches, while Sitobion avenae was the predominant colonising species in the barley field. Relatively to R. padi , S. avenae colonies were about six times more numerous than expected from catches. The yearly abundance of catches of most species did not change significantly during the 20 years, with a few exceptions, significantly correlated to changes in the acreage dedicated to cereal and fodder crops. There was a significant decrease of the autumn catches of both R. padi and the total of BYDV vectors.

The first scorpion fossil from the Cretaceous amber of Myanmar (Burma). New implications for the phylogeny of Buthoidea

A specimen belonging to a new genus and species of fossil scorpion, Palaeoburmesebuthus grimaldii gen. n., sp. n., is described from the Upper Cretaceous amber of Myanmar (Burma). This is the first scorpion to have been found and described from Burmese amber (± 90 Myr). The new genus and species are unquestionable buthoid elements but they are assigned to an incertae familiae until further material may be available for study. To cite this article: W.R. Lourenço, C. R. Palevol 1 (2002) 97–101.

Male advertisement call characters as phylogeographical indicators in European water frogs

Anuran vocalizations are valuable in the determination of species identity and have the potential to discriminate intraspecific variation. We developed novel bioacoustic sampling techniques, based on Fast Fourier Transforms, to increase the precision and sensitivity of male advertisement call analysis and applied the method to European water frogs. This approach robustly separated the three types of north European water frogs (Rana ridibunda, R. lessonae and their viable, fertile hybrid R. esculenta) by their call subunit characteristics. The hybrid frog exhibited a high frequency call component absent from both the parental species. Furthermore, call analysis demonstrated significant intraspecific differences among populations of all three frog types. Call characters of R. ridibunda changed systematically as a function of longitude. This trend may reflect either clinal variation in selection pressures across Europe, or the consequences of drift following postglacial colonization from eastern refugia. High resolution vocalization analysis therefore provides a potentially useful method for investigating intraspecific differentiation and the phylogeographical origins of anuran distributions. © 2002 The Linnean Society of London.

TWO NEW SPECIES OF SUBGENUS CALCEORHOPALUM TSUNEKI FROM CHINA (HYMENOPTERA: SPHECIDAE)

Abstract  Two new species of the subgenus Calceorhopalum Tsuneki of the genus Rhopalum Stephens are described. The new species, Rhopalum ( Calceorhopalum) odontodorsale sp. nov. from Sichuan and Guizhou Province, is similar to R . (C.) spinicollum Tsuneki, but can be distinguished from the latter in the shape of clypeus, vertex with denser and larger punctures, anterior lateral corner of collar with a small tooth, tarsomere I of fore legs rather broad in male, and the shape of male genitalia. Holotype (♂) is deposited in the Insect Collections of Institute of Zoology, Chinese Academy of Sciences. Paratypes (9 ♂♂ 14 2 2 ) are deposited in the Insect Collections of Institute Zoology, Chinese Academy of Sciences and the Insect Collections of Zhejiang Agricultural University separately. The other new species, Rhopalum ( Calceorhopalum) rubigabdominale sp. nov. from Sichuan Province, is similar to R (C.) spinicollum Tsuneki also, but can be distinguished from the latter by the characters of the vertex concave, anterior lateral comer of collar rounded, posterior lateral corner of propleuron with a coarse and long tooth, prepectus with blunt comer medially, head and thorax with denser and larger punctures, abdomen yellowish or reddish brown, and the shape of male genitalia. Holotype (♂) and paratypes (3♀♀) are kept in the Insect Collections of Institute Zoology, Chinese Academy of Sciences.     

Host specificity of Lepeophtheirus crassus (Wilson and Bere) (Copepoda: Caligidae) parasitic on the marlin sucker Remora osteochir (Cuvier) in the Atlantic Ocean

Three species of remoras--Remora brachyptera (Lowe), Remora osteochir (Cuvier), and Remora remora (Linnaeus)--were collected from 4 species of billfishes--Istiophorus platypterus (Shaw), Makaira nigricans Lacepéde, Tetrapturus albidus Poey, and Tetrapturus pfluegeri Robins and de Sylva--on board a Japanese long-liner Shoyo Maru during her cruise in 2002 across the Atlantic. However, only the marlin sucker (R. osteochir) was found to carry a parasitic copepod, Lepeophtheirus crassus (Wilson and Bere, 1936). Although 12 species of parasitic copepods have been reported from billfishes around the world ocean, none of them is L. crassus. Thus, L. crassus is considered a parasite specific to the marlin sucker.
