1. Title, Journal and Authors
- Title : The phytoplankton succession in the lower part of hypertrophic Nakdong River(Mulgum), South Korea
- Journal : Hydrobiologia
- Authors : Kyong Ha, Hyun-Woo Kim & Gea-Jae Joo
- The succession of phytoplankton in Nakdong River, was explained by the weather and meteorological condition.
- In 1994 summer, there was drought in lower part of Nakdon River, which results the severe bloom of cyanobacteria, microcystis.
- Each cyanobacteria has optimal temperature for growth. Aphanizomenon (15 ~ 20), Anabaena (20 ~ 25), Anabaena and Microcystis (25 ~ 35).
- Zooplankton grazing also affects the phytoplankton abundance in fall
- when, Phosporus is limited, cyanobacteria has the advantage for competition
- Usually in Korea, Nitrogen is not the limiting factors because of its abundancy
3. Application to research
- It shows the dominant species of phytoplankton and the factors affects their dominancy in Korea
- it explains the reason for cyanobacteria dominancy in summer, diatom in fall. it can be referenced, when do the researches about cyanobacteria abundancy especially in Korea.
