| 中文摘要 | This study attempted to reveal the effect of solar radiation fluctuation on the dynamics of phytoplankton communities expressed as cell morphology in eutrophic water bodies where the impacts of nutrients could be considered as small. Two morphological descriptors were proposed, cellular projected area () and flattening index (f), which were able to he cellular light-harvesting potential and energy requirement, respectively. A model was established to describe the effects of natural light availability on selecting phytoplankton assemblages with underwater field and mixing process in the water column considered. Based on the data collected from the eutrophic Yanghe Reservoir, the model was derived as where V is bio-volume, lambda is a function of solar elevation angle (theta) and mixing/euphotic depth ratio (z (mix)/z (eu)) in water, and Post-analysis of the model results revealed that species with large and f in general have advantages in spring and winter when underwater light availability is low; by contrast, those with small and f have advantages in summer. Larger and f mean that the cells could harvest more light energy and consumed less, allowing them to be selected under low light availability; and vice versa. We thus concluded that the underwater light field probably the most important factor in selecting phytoplankton morphology in eutrophic water bodies. |
