以排遺分析探討楚南氏山椒魚的食性

Diet of the Salamander Hynobius sonani Analyzed from Its Fecal Pellets

為了解楚南氏山椒魚的食性，我們從台灣中部的合歡山區收集了14個該種山椒魚的排遺。在檢視排遺中的碎片時，依頭部、腹部、螫肢、觸肢器、步足、尾毛、鱗片與翅等的形態特徵確認楚南氏山椒魚的食物項目。結果發現其排遺中共有2綱8目的節肢動物，其中以昆蟲類的鞘翅目與蜘蛛類的蜘蛛目數量最多。有關楚南氏山椒魚以及同屬其他山椒魚的食性在文中也一併被討論。 In order to examine the diet of the salamander Hynobius sonani, a total of 14 fecal drops were collected from the Hehuan Mountain area in the central Taiwan. The prey items in the drops were identified with morphological characters of the fecal fragments, such as heads, abdomens, chelicerae, palpal organs, legs, cerci, scales and wings. The results showed that they were consisted of 2 classes and 8 orders of arthropods, of that insects of Order Coleoptera and spiders of Order Araneae were the most abundant. The diets of J0”uqpcpk and its congenetic species were also discussed.
