金华地区虎纹蛙消化道形态解剖学观察

对金华地区虎纹蛙消化道各部进行了形态解剖学观察.结果表明:虎纹蛙消化道较为明显地分为口咽腔、食道、胃、十二指肠、空肠、回肠、直肠和泄殖腔.同时,对其主要的消化腺肝脏和胰脏进行了观察与测量.观察分析表明虎纹蛙消化道的结构与其食性是相适应的.     

Moss-inhabiting flea beetles (Coleoptera: Chrysomelidae: Galerucinae: Alticini) with description of a new genus from Cangshan,China

The world diversity of moss cushion-inhabiting and moss-feeding flea beetles is documented and discussed. A new genus (Cangshanaltica) with a single new species (Cangshanaltica nigra sp. nov.) from Yunnan Province in China is described and illustrated. It is similar to Benedictus Scherer, Ivalia Jacoby, Minota Weise, Paraminota Scherer, and Phaelota Jacoby. An identification key for all flea beetle genera known to occur in mosses in the eastern hemisphere is provided. http://www.zoobank.org/urn:lsid:zoobank.org:pub:6341724E-BA3F-4979-B226-108D0CA64B92     

中韩虎文化渊源考论

中国和韩国在虎图腾、虎崇拜方面有着共同的特征和文化渊源。在中国,虎在动物文化中的地位仅次于龙排第二,而韩国动物文化中虎占据着更重要的地位。中韩民间故事中老虎均扮演了仁义、义理、友情的形象,韩国民间传说中老虎更是孝义的化身。中国绘画艺术中,多表现老虎的威猛、英勇的一面,而韩国的绘画展示更多的是老虎仁义、报恩的一面。中韩应加强动物文化尤其是虎文化交流,加大弘扬传统虎文化的力度,发挥其在教化人心,扬善惩恶以及净化社会风气方面的作用。     

6种瓢虫的RAPD分析及在分类上应用的研究

利用随机引物分别对6种瓢虫的DNA进行了聚合酶链式反应（RAPD－PCR）的实验。结果显示，用相同引物扩增不同种瓢虫的基因组DNA，扩增产物多态性DNA片段的数目是不同的；两种不同引物的扩增产物中，各自呈现出种、属的特异性片段，其可用于种、属的鉴别；聚类图显示了种、属之间亲缘关系的远近程度，并与形态学分类结果相一致。实验分析还发现：七星瓢虫不同个体间多态性DNA特有带较多，遗传较稳定；龟纹瓢虫与之相比，不同个体间多态性DNA的特有带较少，变异程度较大。     

Temporal organization patterns of epigean beetle communities (Coleoptera: Carabidae,Tenebrionidae) in different successional stages of eastern Mediterranean maquis

This two-year study explores the community structure and temporal dynamics of carabid and tenebrionid beetles in five eastern Mediterranean juniper maquis formations in relation to successional stage. Based on vegetation cover, density and soil pH, the successional stage in two of the sites (Crete, Cyprus) was an earlier state compared with the other three (Attiki, Naxos, Samos), as a result of intense goat grazing. Diversity indices and abundance distributions were compared using morphoecological surrogates of the taxa. Temporal dynamics were regulated more by cumulative species richness than by sharp phenological patterns. The higher values of niche pre-emption parameter and species turnover imply better adaptation of endemic tenebrionids to the rapid change of environmental conditions, compared with carabids. Significantly lower abundance and biomass, and higher evenness and temporal turnover for both families in Crete and Cyprus are ascribed to the reversed course of succession caused by overgrazing.     

巴蜀兵器虎图形性质新说

对虎图形的性质,学术界长期以来存在多种观点。这些观点有其出现时代的合理性,但随着虎图形兵器材料的增加和对巴蜀文化研究的不断深入,其缺陷逐渐暴露出来。通过对学术界图腾说、族徽说、文字说、虎神说4种主要观点的分析,倾向于认为兵器上的虎图形是春秋战国时期特有的,一种巫术色彩浓郁的虎神崇拜的体现,与当时的军事集团有很大关系;虎图形的主要性质一是虎神,二是在图形符号组合中表现出来的图语性质。     

南阳汉画像石中虎的形象艺术阐释

南阳汉画像石中虎的形象寄寓了当时人们特殊的审美情趣,所表现出的飞扬的艺术精神代表着两汉石刻艺术的最高水平,是汉画像石研究不可或缺的内容.     

对虎在我国两大岛屿上分布的历史考察

通过对虎遗存与发掘出的历史文献记载分析、辨证可知,我国的海南与台湾两大岛屿不仅在史前有虎,而且分别延续到宋代与清初,这是对专家、学者迄今多认为我国台湾与海南向来无虎分布观念的突破。     

水底净对斑节对虾仔,幼虾的安全质量浓度与温度的关系

将水温分别控制在 2 0 ,2 5,30℃ ,研究水底净对斑节对虾仔、幼虾的安全质量浓度与温度的关系 .结果表明 :水底净对仔虾的安全质量浓度分别为 1.131,1.0 6 6 ,0 .86 6mg/L ,对幼虾则分别为 1.2 4 0 ,1.0 97,0 .975mg/L ,并且随着温度升高 ,水底净对斑节对虾的安全质量浓度减小 ,在相同温度下 ,水底净对仔虾的安全质量浓度小于对幼虾的安全质量浓度 .     

The clerid beetle,Thanasimus formicarius,is attracted to the pheromone of the ambrosia beetle,Trypodendron lineatum

Summary Sticky traps containing (+)-lineatin, the pheromone of the ambrosia beetle,Trypodendron lineatum, attracted the predatorThanasimus formicarius to about the same extent as traps baited with ipslure, the pheromone blend used for mass-trappingIps typographus. The results indicate thatT. lineatum is an important prey forT. formicarius early in the season before the main prey becomes active. Addition ofexo-brevicomin to ipslure and ethanol and/or -pinene to (+)-lineatin did not significantly influence the catches of the predator.
