查询词典 protozoan

The investigations found that there were obviously different in the species richness and individual abundance in the different sampling site. The number of species and the quantity of individual collected from the littoral zone were much higher than those from the open area. The protozoan colonizing rate on PFU in the littoral zone was also significantly higher than that in the open water.
