中文摘要 | 本研究依照太魯閣國家公園砂卡礑溪流域及步道區域之不同屬性分為水域、步道及五間屋舊部落 (人為開墾地) 等三個調查樣區,調查不同樣區內的兩棲類組成及其數量消長趨勢,作為探討兩棲類棲地利用、季節性變化的分析依據。總計本區兩棲類共有3科10 種,計有盤古蟾蜍、黑眶蟾蜍、拉都希氏赤蛙、澤蛙、斯文豪氏赤蛙、梭德氏赤蛙、日本樹蛙、褐樹蛙、艾氏樹蛙、莫氏樹蛙,其中以盤古蟾蜍、斯文豪氏赤蛙、日本樹蛙、褐樹蛙最為常見。研究結果顯示溫度可能是影響兩棲類活動的重要因子,當溫度過高或過低時,兩棲類活動的能力便降低,此外夏季颱風可能是影響兩棲類活動的另一項因子。而在兩棲類空間利用上,砂卡礑步道及砂卡礑溪上下游地區的兩棲類組成具有明顯的差異,上游地區的兩棲類個體數明顯高於下游地區,物種分布亦有差異,與上下游步道環境組成呈現相同的趨勢,顯示不同環境類型可能是影響兩棲類組成差異的一項因子。 |
英文摘要 | In order to find out how do amphibians make use of habitats and how do they react to the climate, we examined the abundance and composition of amphibians in streams, trails, and the Swigi village along the Shakadang Trail, Taroko National Park. There were 10 species belonging to 3 families of amphibians in this area, including Bufo bankorensis, Bufo melanostictus, Rana latouchii, Rana limnocharis, Rana swinhoana, Rana sauteri, Buergeria japonica, Buergeria robusta, Kurixalus eiffingeri, and Rhacophorus moltrechti. Among which, Bufo bankorensis, Rana swinhoana, Buergeria japonica, Buergeria robusta were the most common in the Shakadang Creek and Trail. Results show that temperature might be a critical factor that affects the amphibian activities. When the air temperature was either too high or too low, the activities of amphibians would drop. Besides, typhoons may also be another factor that influences the amphibian activities. Considering of amphibian compositions in different habitats, both the amphibian species in the Shakadang Trail and the Shakadang Creek differed greatly between the upstream and downstream. The amount of amphibians at the upstream outnumbered the one at downstream; this shows that the distribution and composition of amphibians in the Shakadang Creek and Trail would be influenced by the environment. |
