摘    要:本文分别对采自深圳盐田实验基地和厦门九龙江口水域的多刺裸腹(Moinamacocopa)染色体作了分析研究。结果表明:上述两地区的多刺裸腹染色体数目均为2n=22,染色体形态、大小无明显差异。根据外部形态的比较和遗传特性的分析,可判明两海区出现的多刺裸腹未产生地理上的生态隔离现象,均为亚热带水域同种类型的生物种群。

关 键 词:多刺裸腹■  染色体  深圳  厦门

Abstract:The chromosomes of Moina macrocopa,collected from Shenzhen (Yantian) and Xiamen waters, respectively, are studied. the resuits show that diploid numbers of both cladocera's chromosomes are 2n= 22;and that there are no obvious difference in both chromosome morphologies and sizes. Is is deduced that the two cladoceara are the same species without ecological segregation geographically, belonging to sub-tropical water inhabitants, based on the morphological comparison of the chromosomes and the analysis of their genetic characters.
Keywords:Moina macrocopa  chromosome  Shenzhen  Xiamen
