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.口試委員會審定書 …………………………………………………………… i 誌謝 …………………………………………………………………………… ii 中文摘要……………………………………………………………………iii 英文摘要………………………………………………………………………v 目錄……………………………………………………………………………vii 圖目錄………………………………………………………………………ix 表目錄…………………………………………………………………………x 第一章 前言 1.1 研究動機 ……………………………………………………………….1 1.2 研究目的 ……………………………………………………………….2 1.3 研究流程 ……………………………………………………………….3 第二章 文獻回顧 2.1物種簡介……………………………………………………………4 2.2生物的生活史與生活環境要求………………………………………..6 2.2.1山椒魚的生活史…………………………………………………….6 2.2.2山椒魚的生活環境要求…………………………………………….8 2.3生物體試驗…………………………………………………………14 2.4實驗地域之氣候環境…………………………………………………17 第三章 材料與方法 3.1區域選定………………………………………………………………..19 3.1.1 野溪對照區………………………………………………………19 3.1.2 人為施工區………………………………………………………22 3.2 地域別環境狀況 ……………………………………………………26 3.2.1空氣環境…………………………………………………………27 3.2.2 水質環境…………………………………………………………27 3.2.3 水力環境…………………………………………………………27 3.2.4 土壤環境…………………………………………………………27 3.3 實驗器材………………………………………………………………29 3.3.1環境計測儀器……………………………………………………29 3.3.2生物實驗計測儀器………………………………………………30 3.4 實驗方法………………………………………………………………32 3.4.1環境物質計測……………………………………………………32 3.4.2 生物體計測………………………………………………………35 第四章 結果與討論 4.1 山椒魚陸域及水域棲地環境因子比較………………………………39 4.2山椒魚利用不同基質及角度之季節別攀爬能力差異………………48 4.2.1山椒魚樣本之體型………………………………………………48 4.2.2山椒魚在夏季之攀爬能力差異…………………………………49 4.2.3山椒魚在冬季之攀爬能力差異…………………………………54 4.2.4各種基質之適當坡度設計………………………………………58 4.3阿里山山椒魚與其他高山地區蛙類之行為能力比較………………64 4.4剪趾標記法對於山椒魚攀爬能力之影響……………………………66 第五章 結論與建議 5.1 結論 …………………………………………………………………73 5.2 建議 …………………………………………………………………75 參考文獻 ……………………………………………………………………76 附錄一…………………………………………………………………………84 附錄二…………………………………………………………………………872583321 bytesapplication/pdfen-US阿里山山椒魚水岸邊坡基質攀爬能力剪趾標記法Hynobius arisanensiswater bankmaterialscramble abilitytoe clipping台灣阿里山山椒魚棲地狀況與生物活動力關係研究Study of the habitat and biological motility of Hynobius arisanensis.thesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/56008/1/ntu-95-R93622002-1.pdf
