中文摘要:
      研究似鳊群体间形态差异及与生境的关系,为淮河流域鱼类物种多样性研究和资源保护提供基础资料。选择淮河干流望岗及支流潢河、宿鸭湖,2015年7-8月采集似鳊群体,测量16项形态学可量性状,得到16项比例性状数据;运用SPSS20.0软件对比例性状数据进行单因素方差分析、主成分分析、聚类分析和判别分析。结果显示,望岗群体与潢河群体形态差异较小,两者均与宿鸭湖群体形态差异较大;相比望岗群体和潢河群体,宿鸭湖群体的胸鳍、腹鳍明显短小,表现出一定的退化;头部更瘦削,尾柄更加粗壮;望岗与潢河生境相似,宿鸭湖与它们生境差异较大,推测3个似鳊群体间的形态差异与其生境有关。胸鳍长/体长、腹鳍长/体长可作为在形态上区分3个似鳊群体的主要依据。
英文摘要:
      Pseudobrama simony widely inhabits the Huaihe River basin and plays an important role in maintaining material cycling, energy flow and biodiversity within the basin. In this study, we analyzed the morphological differences of three P. simoni populations in the Huaihe River basin: Wanggang River, Huanghe River (a tributary of Huaihe River) and Suyahu Reservoir. The objectives were to explore the effect of habitat on fish morphology and provide basic data for conserving biodiversity and aquatic resources in the basin. In July and August of 2015, P. simoni specimens were collected from each of the three areas and 16 characteristic morphometrics were compared by One-Way ANOVA, principal component analysis, cluster analysis and discriminant analysis. The morphological characteristics of the Wanggang and Huanghe River groups were similar, while the Suyahu Reservoir group was clearly different. Morphological differences between populations were those primarily associated with swimming. The pectoral and pelvic fins of the Suyahu population were smaller and shorter, the head was thinner and the caudal peduncle was thicker compared with the Wanggang and Huanghe populations. Wanggang River and Huanghe River habitats are similar, with flowing water, while the water in Suyahu Reservoir is quiescent. The morphological differences between the three P. simoni populations were therefore attributed to a difference in habitat, i.e., adaptations to swimming in standing water vs. flowing water.
