中国近海类鸠螺科研究及三新种记述(软体动物门,类鸠螺科)

类鸠螺科Columbariidae属软体动物门、腹足纲、前鳃亚纲、新腹足目。是软体动物门中一个较小的类群。分布于热带和亚热带,主要栖息于深海区域,较少见。我所在历年的海洋调查和全国海洋综合调查时,仅在南海和东海南部采到3个标本。1999年4月中国科学院南沙综合科学考察队,分别在南沙群岛海区6号站水深500m和14A站水深480m处共采到7个标本,其中有3个是生活标本。除台湾的赖景阳(1994)曾报道过本科的一个种外,目前在我国对本科尚未做过系统研究。作者通过对我们采集的标本进行整理研究,共鉴定出类鸠螺科2属6个种,其中有3个新种和1个新纪录。     

中国沿海蛾螺科5属10种28S rRNA基因的系统学分析

目前已报道在我国分布的蛾螺科种类有13个属,约31个种,系统学和分类地位仍存在较大的争议.本研究利用核糖体大亚基28S rRNA的部分序列对我国辽宁、山东、福建沿海蛾螺科5属10个种的系统发生进行了分析.通过PCR获得了大约1400 bp的片段,测序之后,通过遗传分析软件对序列进行了比对分析,以骨螺科的脉红螺作为外群,利用Neighbor-Joining (NJ)法和Minimum Evolution (ME)法建立了系统树.结果显示,所研究的蛾螺科5属10个种可以被分为5个亚群:第一大分支为香螺亚群,包括Neptunea属的香螺、新英格兰蛾螺、Neptunea eulimata Dall、和一个未知种以及Siphonalia属的略胀管蛾螺;第二个分支为侧平肩螺亚群;第三个分支为荻曷莺突坪6曷菅侨海坏谒母龇种止芏曷菅群;第五个分支为方斑东风螺亚群.由系统学分析可知,香螺是较为进化的种;未知种为香螺属内的种;略胀管蛾螺与Neptunea属的种类亲缘关系较近,序列相似系数为0.9%-1.4%,已经达到了属内水平,建议将略胀管蛾螺归为Neptunea属.

金宝螺营养成份的初步研究

金宝螺(Ampullaria gigas)又名福寿螺,大瓶螺,苹果螺,属软体动物门腹足纲(前鳃亚纲)腹足目瓶螺科瓶螺属,原产于南美洲亚马逊河流域,是一种大型的淡水食用螺类,其肉质鲜嫩、营养丰富,深受人们的喜爱。发展金宝螺养殖,对改善人们的食品结构以及解决鱼虾和河蟹等名特优水产类的动物性蛋白饵料,具有重要价值。然而纵观国内外文献资料1-6,迄今为止均未对金宝螺的营养成分和氨基酸组成分析作全面系统的报道。为此1998-1999年,作者对金宝螺的营养成分和氨基酸组成进行测定,为金宝螺的营养学及人工高产养殖研究提供科学依据,现将结果报道如下。

Neue sesquiterpene,triterpene, flavanone und andere aromatische verbindungen aus Flourensia heterolepis

The investigation of a further Flourensia species afforded in addition to already known compounds 12 new sesquiterpene acids isolated as their methyl esters, a new eudesmane diol, four lupane derivatives and two flavanones, two cinnamic acid derivatives, also isolated as methyl esters and a ketone. The structures are elucidated mainly by spectroscopic methods and by some chemical transformations. Several of the compounds isolated are more or less similar to those isolated from other Flourensia species; the considerable amounts of eudesmanes, however, are unusual. The overall picture of the genus is still relatively uniform. Close relationships to Helianthella are obvious, while to Helianthus, placed in the same subtribe, no clear relations are visible.

Establishment of a new amphileptid genus, Apoamphileptus nov. gen. (Ciliophora, Litostomatea, Pleurostomatida), with description of a new marine species, Apoamphileptus robertsi nov. spec. from Qingdao, China

A new pleurostomatid genus Apoamphileptus is described, which is diagnosed as: Belonging to the Amphileptidae with spica on right side; on each side of the cell, a single perioral kinety, which encircles the cytostome and does not extend to the posterior end of the cell; somatic kineties of both sides near ventral margin shortened and forming a postoral suture; two to several extra fragments with densely arranged dikinetids located in anterior portion of left side. As the type species, the morphology and infraciliature of Apoamphileptus robertsi nov. spec., isolated from a shrimp-farming pond near Qingdao (Tsingtao), China, have been investigated using living observations and the protargol silver impregnation method. The diagnosis for this new species is: Apoamphileptus 90-180 x 30-60 microm in vivo, body elongate pyriform-shaped and slightly flattened; with one cross-striated band along the cytostome; 2-6 (generally 4) large macronuclear nodules, one micronucleus; 33-43 right somatic kineties; left side 6-8 kineties; two extra anterior fragments on left side; about 13 contractile vacuoles dispersed throughout whole body; extrusomes absent or not recognizable; marine habitat. Some morphologically related morphotypes are discussed and tabulated. Regarding the pattern of infraciliature and other morphological features, the well-described fresh-water species, Amphileptus claparedii Stein, 1867 is believed to be a member of this new genus, hence a new combination is suggested: Apoamphileptus claparedii (Stein, 1867) nov. comb.

Redescription of a poorly known marine ciliate, Leptoamphisiella vermis Gruber, 1888 n. g., n. comb. (ciliophora, stichotrichia, pseudoamphisiellidae), from the Yellow Sea, China

Leptoamphisiella vermisGruber, 1888 n. g., n. comb. (basionym Epiclintes vermisGruber, 1888) is an extraordinarily large and worm-like marine stichotrichous ciliate. Based on a population isolated recently from coastal waters of Qingdao, China, the living morphology and infraciliature are redescribed and its taxonomic position is defined. Accordingly, a new diagnosis for this species is suggested: large, marine Leptoamphisiella with a conspicuous layer of pellicular alveoli; 400-1000 microm x 40-70 microm in vivo; body band-like, highly flexible; about 40 membranelles; always three frontal and two buccal cirri; 52-80 transverse cirri (TC) extending to the posterior end of the buccal field; 57-79 left midventral and 44-62 right midventral cirri; 62-102 cirri in left and 63-91 cirri in right marginal rows (MR); 9-13 dorsal kineties that extend the full body length; about 100 macronuclear nodules and 5-13 micronuclei. The diagnosis for the new genus is as follows: vermiform Pseudoamphisiellidae with strongly contractile body, differentiated frontal, buccal, and highly developed TC; two remarkably separated midventral rows; one MR on each side of the body; frontoterminal and caudal cirri absent. Leptoamphisiella vermis n. comb. is fixed as the type species of the new genus.
