Using Structural Equation Modeling to study the relationship between the sea anemone Phymanthus strandesi and ecological factors in the seagrass bed of Hsiao-Liuchiu Island / 利用結構方程模式來探討小琉球海草床上柱形瘤海葵Phymanthus strandesi與生態因子之關係

碩士 / 國立中山大學 / 海洋生物研究所 / 99 / Seagrass bed is a highly productivity ecosystem, it also provides habitats for animals and plays an important role in stabilizing the substrate. The sea anemone Phymanthus strandesi is very abundant in the seagrass bed of Thalassia hemprichii on Hsiao-Liuchiu Island. Structural Equation Modeling (SEM) was used to investigate the relationship between P. strandesi and some environmental factors, which affect the distribution of this species at Tuozaiping tidal flat (N 22°20"55'' E 120°21"49''), Hsiao-Liuchiu Island. Light and temperature were also manipulated in the laboratory to test their effect on the hiding response of P. strandesi. The results of SEM show that the abundance of T. hemprichii showed very weak positive relation with P.strandesi. On the other hand, soil depth on the seagrass bed might be the main factor that affects the distribution of P. strandesi. In high a temperature situation (i.e. over 38°C), all the sea anemones in the experimental container hided into the sand.
However, only some sea anemones hid when exposed to strong light (i.e. 5030 lum/ft²) after one and half hours.
