چکیده
Harmful cyanobacterial blooms in eutrophic water bodies pose a major threat to the environment and human health. The morphological functional traits of cyanobacteria play important roles maintaining their competitive advantages. To explore regulatory mechanisms different bloom-forming cyanobacteria, we performed one-year-long phytoplankton survey from November 2016 October 2017 Lake Chaohu, China. colony size cell diameter dominant were measured, relationships analyzed. results showed that Dolichospermum flos-aquae Microcystis aeruginosa lake. was species during summer; growth surpassed Microcystis, became late autumn, winter spring. From spring, decreased 222.25 μm 10.51 μm, individual increased 6.5 7.4 μm. summer enlarged sizes reduced diameters. 83.71 spring 196.71 while cells remained essentially at 3–4 March Chaohu. relationship between significantly positive, not significant. These suggest may maintain biomass through trade-off size, flexible mechanism exists. This study seeks improve our understanding how dominance by regulating traits.

Seasonal changes in icefish diel feeding patterns in Lake Chaohu, a large shallow eutrophic lake of China
Seasonal changes in the diel feeding patterns of the zooplanktivorous icefish (Neosalanx taihuensis), which is an endemic species of China, were studied in the large, shallow eutrophic Lake Chaohu of China during the autumn of 2002 and summer of 2003. The results of the diel feeding rhythm indicate that icefish is a visual particulate feeder. There were large differences in diet composition and...
