Abstract
With the tourism developing in recent years, there are often concrete constructions by the creeks in order to protect the safety of the tourists, but the effect of concrete on the environment and the mobility of certain species are still unknown. This research is working on a probe into different water bank materials adaption that effect Hynobius arisanensis’s motility in the national park of Alishan. Comparing concrete area and other two areas where to keep primitive stream, concrete constructs lead to the velocity of flow increase; streams shallow and then effect water quality. In biological motility study, choose the existing moss; rock; wood; soil and concert as water bank materials measure the scramble ability of Hynobius arisanensis. According to the seasonal humidity changes in winter and summer of Alishan area, Hynobius arisanensis‘s scramble ability in high humidity high temperature and high humidity low temperature are discussed to find an interval of slope increasing and scramble ability drops rapidly. In the result, the scramble ability of Hynobius arisanensis is slightly decrease in low temperature, take 45°as an example, in winter the average of scramble ability decline 8% than in summer. The upper limit of design slope suitable for Hynobius arisanensis, on the moss surface, propose ≦60°is better；as the surface on rock and wood, propose ≦45°, other amphibians of alpine areas in Taiwan such as Bufo bankorensis is considered, then the slope ≦15°is suitable. Concrete as the water bank material, propose the slope ≦45°；soil as the water bank material, the slope are prefer to ≦30°. In this research also discussed Hynobius arisanensis’s scramble ability effected by toe clipping method-Martof(1953). The result shows that Hynobius arisanensis’s scramble ability is also decrease after toes were cut. Sample quantity is limited in this research and hope that sample number of Hynobius arisanensis can be increased and could be helpful for further researches in the future.
