亚热带湖泊中一种剑水蚤──Mesocyclops notius Kiefer的形态及生态学研究

MORPHOLOGICAL AND ECOLOGICAL STUDIES ON A CYCLOPOID COPEPOD, MESOCYCLOPS NOTIUS KIEFER IN A SUBTROPICAL CHINESE LAKE

摘要: 本文报道了对一亚热带湖泊中的Mesocyclops notius的形态及生态学研究。将从扁担塘采得的标本形态学特征与Kiefer和Velde从澳大利亚的标本的形态学特征进行了比较.在扁担塘,M. notius与2种温剑水蚤──Thermocyclops taihokuensis Harada和T. brevifurcatus Harada为春季和夏季剑水蚤的优势种,而Cyclops vincinus vincinus Vljanin为冬季的优势种。

Abstract: This paper reports morphological and ecological studies on Mesocyclops notius Kiefer from a subtropical Chinese lake. Morphological characers of this species from Lake Biandantang were compared with Kiefer's and Van de Velde's studies on Aistralian specimens. In Lake Biandantang, M. notius associated with Thermocyclops taihokuensis Harada and T. brevifucatus Harada, dominated the planktonic Cyclopoida in the spring and the summer, while Cyclops vincinus vincinus Uljanin dominated in the winter.
