    Comparison of morphological defences in asexually and sexually reproduced eggs of Daphnia (D. galeata and D. similis) against fish kairomones

    In the present study, we investigated morphological changes of hatchlings from asexually and sexually produced eggs of Daphnia galeata and D. similis against fish kairomones. In both species, hatchlings from asex...

    Prediction and Elucidation of Population Dynamics of the Blue-green Algae Microcystis aeruginosa and the Diatom Stephanodiscus hantzschii in the Nakdong River-Reservoir System (South Korea) by a Recurrent Artificial Neural Network

    Artificial neural networks were applied to the prediction and elucidation of two bloom forming algal species in the Nakdong river-reservoir system. The lower Nakdong River, which has characteristics of both ri...

    Vertical distribution of Microcystis population in the regulated Nakdong River, Korea

    The vertical distribution of a bloom-forming Microcystis population was studied based on the relevant limnological parameters obtained from the lower Nakdong River (Mulgum) during the summer of 1994. Over three ...

    Enhancement of nitrogen fixation inAnabaena flos-aquae (Cyanobacteria) via low-dose ultrasonic treatment

    Low-dose (50 W), short-duration (5 min) ultrasonic treatments were delivered to log phase batch cultures of the cyanobacteriumAnabaena flos-aquae grown in nitrogen-free medium. Near the mid-point of nine-day expe...
