肠道鞭毛虫群落及在宿主白蚁分类学上的意义

于国内五个常见白蚁种肠道内共记录到十七个鞭毛虫种。鞭毛虫种群具特异性和稳定性。群落相的变异度反映了宿主白蚁亲缘关系的离散度。异域同种白蚁肠道鞭毛虫群落显示稳定的同一相,同属异种白蚁的鞭毛虫群落部分相同;异科异属或同科异属白蚁的鞭毛虫群落绝然相异。 鉴于传统的生物分类法已明显地显示出其片面性及局限性,为此,人们正试图从其它学科领域,各个不同角度去探索能更客观反映各物种在系统发生上关系的新分类法。迄今,精确定性的生化分类、免疫分类和以群体力对象的定量的数量分类等已倪露头角,从而为以形态描述为主的经典生物分类学注入了新的活力。 本文试图通过对白蚁肠道鞭毛虫群落及种群的研究而借以探讨其在宿主白蚁系统分类研究中的潜在意义。

THE COMMUNITY OF INTESTINAL FLAGELLATES AND ITS SIGNIFICANCE IN THE CLASSIFICATION OF THEIR HOST TERMITES

It is reported in this article that seventeen species of flagellates have been recorded in the intestines of five termites species which are most common in chines cities. It is proved that the flagellate community of each termite species is characteristic and stable. The constituent ratio of the community in each termite species is basically stable, wherever it is collected from different cities. The communities in different species which all belong to one termite genus are however not the same completely. The flagellate communities in different termite genura are different absolutely. According to above resultes, we believer that the research of flagellate community will be promote the classification of termites.
