| 中文摘要 | 人為不當開發造成臺灣水岸混凝土化日益嚴重，但陸水共生之生物大部分生態系統行為多在水岸邊發生，而臺灣目前尚無相關設計規範可供參考。本研究選擇七種涵蓋臺灣各地水域，與水岸環境密切的蛙類，探討棲地與行為特性，期能改善水岸混凝土化問題。實測其體長、體重、趾表面積、四肢吸附能力、跳高與跳遠能力，以最適合的四種基質與對照組混凝土比較，配合較佳之五種邊坡坡度，量測蛙類活動能力。依臺灣季節影響溫濕度的變化對基質表面之影響，探討對於蛙類行為能力的影響。實驗結果得知，以邊坡45度為例，比較同科且相近體型之面天樹蛙與日本樹蛙之單位體重吸附能力在卵石基質與木質基質上，日本樹蛙能力分別只有面天樹蛙能力的17%與16%。至於體型與行為能力之差異性，以同為赤蛙科之斯文豪氏蛙與腹斑蛙為例，雌性第一群中，斯文豪氏赤蛙較腹斑蛙在體重方面高63%；體長高30%；四肢肉趾表面積高44%；而行為能力方面，跳高能力高15%；跳遠能力高29%，可知同科別中，體型與行為能力有明顯差異。在吸附能力方面，蛙類體型影響極大，依蛙類體型由大而小，依序為盤古蟾蜍、褐樹蛙、拉都希氏赤蛙與日本樹蛙等作比較，大部分之蛙類適應坡度能力，顯示應小於30度為佳。若將條件設定為木質邊坡30度，盤古蟾蜍幾乎無吸附能力；日本樹蛙則高出褐樹蛙59%；褐樹蛙高出拉都希氏赤蛙67%。本研究之水岸邊坡材質與坡度組合，對於日後從事改造地方本土化水岸生態工程技術之相關工程人員能提供有用資料。 |
| 英文摘要 | The concreting process on water banks caused by inappropriate human development became a serious problem in Taiwan; however, most ecosystems of amphibian animals took place on lake banks, yet there was no related design solutions offered in Taiwan. This research selected seven species of frogs in Taiwan. To discuss their habitats and behavioral characteristics in order to mange the problem of water banks. With measuring of each frog’s body length, weight, toe pad area, sticking ability, high jump ability, and long jump ability, this experiment was designed to compare concrete with four substrates which found most suitable in the experiment. Matching then with five appropriate bank angles to test frog’s motility, and furthermore, to identify the relation between frog’s abilities and surface substrates of water banks as humidity and temperature differ in four seasons. The result showed that if comparing per weight’s sticking ability of Chirixalus idiotocus and Buergeria japonicus, those two in the same family and similar size, on the 15° slope, Buergeria japonicus’ sticking ability would down to 16% of Chirixalus idiotocus’s. If we took the example of Rana swinhoana and Rana adenopleura of Rana family to discuss their body sizes and behavioral ability’s differences, in the first female group, the weight of Rana swinhoana’s was 63% heavier than Rana adenopleura, as body length 30% longer than Rana adenopleura, and toe pad area 44% larger than Rana adenopleura. In the aspect of behavioral ability, Rana swinhoana performs 15% better in the field of high jump ability and 29% better with long jump. What was found in the results was that even in the same family, each frog may differ significantly in body size and behavioral ability. In the aspect of sticking ability, the body-size variable was an crucial factor, and if frogs were ranked by size, the o rder was – Bufo bankorensis, Burgeria roubsts, Rana latouchii, and Buergeria japonicus – generally most frogs adapted better on bank slope under 30°. Bufo bankorensis almost showed no sticking ability at the 30° slope, wooden bank, while Buergeria japonicus’ sticking ability was a59% stronger than that of Burgeria roubstus, and Bureria roubstus’ sticking ability was 67% stronger than Rana latouchii’s. This research adopted multiple combinations of lake banks’ materials and angles could serve as a reference for technicians in future ecological engineering on lake banks in Taiwan. |
