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

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.
