| contents | Sustainable Management of Filamentous Algae in Freshwater Ecosystems: Insights from sp. Life History, Reproductive Tactics, and Growth Ecology. Zhao, Liangjie Guo, Liangxin Tan, Chenxi Tang, Yongtao Ma, Yuanye Zhang, Zhen Cheng, Yongxu Qian, Chen Freshwater ecosystems are increasingly degraded by blooms, prompting a need to understand its reproductive characteristics for effective control. We combined continuous microscopical monitoring and single-factor and orthogonal experiments, to characterize the life history and reproductive and growth response to different nutrients, pH, temperature, and light conditions of a bloom-forming sp. A novel mode was observed, in which mature sporangia and gametangia rupture to extrude a pyknotic cytoplasmic mass, inside which zoospores and gametes complete maturation and release. The peak zoospore production occurred in Aquatic No. 6 medium at pH 5, 35 °C, and 54 µmol m s, whereas maximum gamete release was recorded in Knop medium at pH 4, 30 °C, and the same irradiance, with temperature being the principal driver for zoospores and nutrient regime for gametes. Growth trials further revealed that low-N and -P conditions sustain growth, whereas nutrient-rich conditions favor reproduction. In addition, pH 4-5, 35 °C, and 54 µmol m s conditions favored propagule formation, while pH 7-8, 25 °C, and 81 µmol m s maximized biomass. These findings provide a basis for predicting bloom dynamics and offer references for sustainable management of in freshwater ecosystems. |
